Presentation Quality assurance 0

Quality certified to ISO 9001

A major advantageSchneider Electric has integrated a functional organisation into each of its units. The main mission of this organisation is to check the quality and the compliance with standards.This procedure is:b uniform throughout all departments;b recognised by many customers and approved organisations.But it is above all its strict application that has enabled recognition to be obtained by an independent organisation: The French Quality Assurance Association (FQAA).The quality system for the design and manufacture of SM6 units has been certified in conformity with the requirements of the ISO 9001 quality and ISO 9002 quality assurance model.

Meticulous and systematic controlsDuring manufacture, each SM6 is subject to systematic routine testing which aims to check the quality and conformity:b sealing testing;b filling pressure testing;b opening and closing rate testing;b switching torque measurement;b dielectric testing;b conformity with drawings and plans.The results obtained are written and reported on the test certificate for each device by the quality control department.

The environmental management system adopted by Schneider Electric production sites that produce the SM6 have been assessed and judged to be in conformity with requirements in the ISO 14001 standard.

Vacuum type circuit breaker: Evolisb Gas tightnessThe Evolis circuit breaker comprises three separate pole units fixed on a structure supporting the control mechanism. Each pole encloses all of the active parts in an insulating enclosure, under vacuum, and its gas tightness is systematically checked in the factory.

b Operating safety v the magnetic field is applied along the contact axis of the vacuum type circuit breaker.This process diffuses the arc in a regular manner with high currents. It ensures optimum distribution of the energy along the compact surface so as to avoid local hot spots.The advantages of this technique:v a simplified vacuum type circuit breaker which is consequently very reliable,v low dissipation of arcing energy in the circuit breaker,v highly efficient contacts which do not distort during repeated breaking,v significant reduction in control energy.

By operating mechanism safety

Reliable operating mechanismb Switchgear status indicator: Fitted directly to the mobile equipment’s shaft, these give a definite indication of the switchgear’s position. (appendix A of standard IEC 62271-102.).b Operating lever: This is designed with an anti-reflex device that stops any attempt to re-open the device immediately after closing the switch or the earthing disconnector.b Locking device: Between one and three padlocks enable the following to be locked:v access to the switching shaft of the switch or the circuit breaker,v access to the switching shaft of the earthing disconnector,v operating of the opening release push-button.

Simple and effortless switchingMechanical and electrical controls are side by side on the front fascia, on a panel including the schematic diagram indicating the device’s status (closed, open, earthed):b Closed: the mobile equipment is operated via a quick acting mechanism, independent of the operator. No energy is stored in the switch, apart from when switching operations are taking place.For combined switch fuses, the opening mechanism is armed at the same time as the contacts are closed.b Opening: the switch is opened using the same quick acting mechanism, operated in the opposite direction.For circuit breakers and the combined switch fuses, opening is controlled by: v a push-button,v a fault.b Earthing: a specific control shaft enables the opening or closing of the earthing contacts. Access to this shaft is blocked by a cover that can be slid back if the switch is open but which remains locked in place if it is closed.

Voltage presence indicatorThis device has integrated VPIS (Voltage Presence Indicating System) type lights, in conformity with IEC standard 61958, enabling the presence (or absence) of voltage to be checked on the cables.

Insensitivity to the environmentb An internal sealed enclosure, contains the active parts of the switchgear (switch, earthing disconnector). It is filled with SF6 in accordance with the definitions in IEC recommendation 60298 for “sealed pressure systems”. Sealing is systematically checked in the factory. b Parts are designed in order to obtain optimum electrical field distribution.b The metallic structure of cubicles is designed to withstand and aggressive environment and to make it impossible to access any energised part when in operation.

By internal arc protection

Standard IEC 60298 appendix AA indicates a method for testing switchgear in metal enclosures under internal arcing conditions. The aim of this test is to show that an operator present in front of a switchboard would be protected against the effects of an internal fault.

To enhance the safety of people, it is desirable to provide as high a degree of protection as possible by evacuating the effects of internal arcing using:b evacuation systems which direct gases towards the top or the bottom of the switchboard enabling over pressure to be limited in the case of an internal fault in the compartments; b channelling and evacuating hot gases towards an external area, which is not hazardous for the operator;b materials which are non-inflammable for the cubicle;b reinforced panels.

Consequently:

The SM6 is designed to offer a good level of safetyb Control of the architecture:v compartment type enclosure.b Technological control:v electrotechnical: modelling of electrical fields,v mechanical: parts produced using CAD systems.b Use of reliable components: v choice of materials, v earthing switch with closing capacity.b Devices for total operating safety:v voltage presence indicator on the front face,v natural reliable interlocking,v locking using keys or padlocks.

Internal arc withstand of the cubiclesb 2 versions are available:v basic version: 12.5 kA. 0.7 s,v enhanced internal arcing withstand: 16 kA. 1 s.

SM6 internal arc (in conformity with IEC 60298 appendix AA)In its internal arc version, the SM6 range has successfully passed all of the type testing relative to standard IEC 60298 (6 acceptance criteria).The materials used meet the constraints for which the SM6 is designed. The thermal and mechanical forces that an internal arc can produce are perfectly absorbed by the enclosure.An operator present in the front of the SM6 switchboard during an internal fault will not be exposed to the effects of arcing.

SM6 proposes several options to install an internal arc enhanced switchboard b 3-sides internal arc protection: Case of an SM6 switchboard positioned against the wall, access to the rear of the cubicles is impossible, internal arc protection on three sides is sufficient. b 4-sides internal arc protection:For SM6 switchboards installed in the middle of a room, 4-sides internal arc protection is necessary in order to protect an operator moving around the switchboard.

Choice of exhaustThe choice depends on the civil engineering:b Upwards exhaust: A ceiling height greater than 2200 mm is necessary.b Downwards exhaust:Civil engineering with an adequate volume is necessary.

VIP 35 protection relayIntegrated in the DM1-S and DMV-S cubiclesThe VIP 35 is an independent relay without an auxiliary power supply, powered by the current sensors, and actuating a Mitop release unit. VIP 35 provides protection against phase-to-phase faults and against earthing faults.Phase protectionb phase protection is achieved by a definite time threshold which functions from 1.2 times the operating current (Is). Earthing protectionb earthing fault protection functions with the residual current measurement taken from the sum of the secondary currents in the sensors. This is taken via a CRc, 8 A to 80 A gauge. b earthing protection is inverse definite time: its threshold and time delay can be set.

VIP 300 LL protection relayIntegrated in the DM1-S and DMV-S cubiclesVIP 300 provides protection against phase-to-phase and phase-to-earth faults. A choice of trip curves and the large number of possible settings mean that it can be used in a large variety of selectivity layouts.VIP 300 is an independent relay powered by the current sensors; it does not require an auxiliary power supply. It actuates a release unit.Phase protectionb phase protection is via two independently adjustable thresholds:v the lower threshold can be chosen to be inverse definite time or definite time. The definite time curves are in conformity with IEC standard 60255-3. They are either of inverse, very inverse or extremely inverse type.v the upper threshold is inverse definite time.Earthing protectionb protection against phase-to-earth faults uses the residual current measurement, taken from the sum of the secondary currents in the sensors. This is taken via a CRa X1 gauge: 10 to 50 A and X4: 40 to 200 A or via a CRb X1 gauge: 63 to 312 A and X4: 250 A to 1250 A.b as for phase protection, phase-to-earth protection had two thresholds that can be independently set. Signallingb two indicators show the origin of the trip operation (phase or earth). They remain in position after the relay power supply has been cut.b two led indicators (phase and earth) show that the lower threshold has been exceeded and that its time delay is currently in progress.

VIP 200 and VIP 201 protection relayIndependent definite time protection device integrated with the SFset circuit breaker Protection relay without an auxiliary power supply. Dedicated to the protection of transformers, this relay also enables very accurate selectivity to be obtained.VIP 200 and VIP 201 protection units in the Fluarc SFset circuit breaker, without an auxiliary power supply, protect against phase-to-phase and earth faults. All these protection devices have wide settings ranges for their trip currents.

Motor option and releases for Evolis circuit breakers 0

Charging motor and associated mechanism (MCH)The MCH unit arms and rearms the energy storage springs as soon as the circuit breaker is closed. This enables instant reclosing of the device after opening. The arming lever is only used as back up control in the absence of an auxiliary voltage.The MCH is equipped as standard with a CH limit switch. This contact indicates the “armed” position of the mechanism (spring armed).

Low energy release (MITOP)This specific coil actuates the opening mechanism of the poles to trip the circuit breaker. It comprises a low energy consumption electromagnet.

Any tripping caused by the Mitop release is indicated momentarily by an SDE type changeover contact. This release unit also includes a coil enabling the remote rearming of the SDE contact.Comment: to use the MITOP release requires the adjustment of a time delay to be set by the protection relay in order to ensure a circuit breaker operating time of 45-50 ms.

Shunt trip release (MX)This causes instant opening of the circuit breaker when energised. Permanent energising of the MX locks the circuit breaker in the “open” position.

Motors protection with CRM units 0

The current rating of fuses installed in CRM units depends on:b motor current rating In;b starting current Id;b frequency of starts.The fuses rating is calculated such that a current equal to twice the starting current does not blow the fuse within period equal to the starting time.The adjacent table indicated the ratings which should be used, based on the following assumptions:b direct on-line startup;b Id/In ð 6;b pf = 0.8 (P ð 500 kW) or 0.9 (P > 500 kW);b � = 0.9 (P ð 500 kW) or 0.94 (P > 500 kW).The indicated values are for Fusarc fuses(to DIN standard 43-625).

Example:Consider a 950 kW motor at 5 kV.

Id = 6 x In = 780 A

Then select the next higher value, i.e. 790 A.For six 5-second starts per hour, select fusesrated 200 A.

Selection of fusesThe color code is linked to the rated voltage of the fuse.

Maximum switchable power (kW)(direct on-line startup, six 5 sec. starts per hour)

Note: the same motor could not be protected for 12 starts per hour since the maximum service voltage for the required 250 A rated fuses is 3.3 kV.

Access to fusesAccess is via the front with the front panel removed.Fuses may be removed without tools by simply pulling them forward. The field deflector pivots and automatically returns to its position.Replacement of fusesWhen fault clearance results in one or two blown fuses, it is still common practiceto replace only the blown fuses.However, though the remaining fuse(s) may apparently be in good condition, their operating characteristics are generally reduced due to the short-circuit.If non-blown fuses remain in service, they may blow even at very low over-current values. In systems where continuity of service is of importance, it is recommended to replace all three fuses, in compliance with IEC recommendation 60282.1.Please note: all three fuses must come from the same range: Fusarc or Fusarc CF (they have different fusion curves).

Connections Connections selection table 0

The ageing resistance of the equipment in an MV/LV substation depends on three key factors:b the need to make connections correctlyNew cold fitted connection technologies offer ease of installation that favours resistance over time. Their design enables operation in polluted environments under severe conditions.b the impact of the relative humidity factor The inclusion of a heating element is essential in climates with high humidity levelsand with high temperature differentials.b ventilation control The dimension of the grills must be appropriate for the power dissipatedin the substation. They must only traverse the transformer area.

Network cables are connected:b on the switch terminals; b on the lower fuse holders; b on the circuit breaker’s connectors.The bimetallic lugs are:b round connection and shank for cables ð 300 mm2; b square connection round shank for cables > 300 mm2 only. Crimping of lugs to cables must be carried out by stamping.The end connectors are of cold fitted typeSchneider Electric’s experience has led it to favour this technology wherever possible for better resistance over time.The maximum admissible cable cross section: b 630 mm2 for 1250 A incomer and feeder cables; b 300 mm2 for 400 - 630 A incomer and feeder cables ;b 95 mm2 for transformer protection cubicles with fuses.Access to the compartment is interlocked with the closing of the earthing disconnector.The reduced cubicle depth makes it easier to connect all phases.A 12 mm Ø pin integrated with the field distributor enables the cable end lug to be positioned and attached with one hand. Use a torque wrench set to 50 mN.

Floor preparationUnits may be installed on ordinary concrete floors, with or without trenches depending on the type and cross-section of cables.Required civil works are identical for all 400 - 630 A units.To reduce the depth of trenches by 400 mm (for the 400 - 630 A units), which in many cases is sufficient to eliminate trenches altogether, units may be installed on a concrete footing prepared when pouring the floor.Installation of 400 - 630 A units on a footing:b enables installation in rooms where trenches are not possible;b in no way affects substation switching operation;b for the 1250 A units DM1-A and DM1-W, a floor void must be foreseen.

Fixing of unitsWith each otherThe units are simply bolted together to form the MV switchboard (bolts supplied). Busbar connections are made using a torque wrench set to 28 mN.On the floorb for switchboards comprising up to three units, the four corners of the switchboard must be secured to the floor using:v M8 bolts (not supplied) screwed into nuts set into the floor using a sealing pistol,v screw rods grouted into the floor.b for switchboards comprising more than three units, the number and position of fixing points depends on local criteria (earthquake withstand capacities, etc.), each unit may be fixed as necessary.b position of fixing holes b depends on the width a of units:

Add to height:(1) 450 mm for low-voltage enclosures for control/monitoring and protection functions. To ensure uniform presentation, all units (except GIM and GEM) may be equipped with low-voltage enclosures. (2) depending on the busbar configuration in the VM6 unit, two types of extension units may be used:b to extend a VM6 DM12 or DM23 unit, use an extension unit with a depth of 1060 mm;b for all other VM6 units, a depth of 920 mm is required.(3) for the 1250 A unit.
