Conclusion of Survey
§ FACTS§ Operating mechanisms are responsible for almost all
major and minor failure§ SF6 gas leakage is the second problem after
operating mechanism.§ Major or minor failure because of interrupter is
negligible.§ Direction of CB development
§ Interrupter chamber should be very energy efficient§ Use of simpler and less mechanically stressed
operating mechanism§ SF6 gas leakage should be minimized by inherent
strong design.

Current TransformersDesign Advantages
Quartz FillingüEmbedding active parts in quartz gives advantageto CT for withstanding strong vibrations duringtransportation and earthquake and provide excellentdynamic strength during short circuit faultüBeing a bad conductor of heat, rapid heating andcooling is avoided , hence eliminates possibility ofgas bubble formation.üQuartz being hygroscopic in nature absorbs theremenant moisture from oil thus improves the qualityof oil.
üDry N2 gas without movingparts, No maintenanceüMinimum 15% gas comparedto oilüAll O rings and gaskets underoil which ensures better gasketlife and leak detectionüSS Bellows with top sealing forhigher currents
Reliable Expansion system
Optimized primary designüPrimary conductor is hollow Aluminium tubeand facilitates heat dissipation by oilcirculation through tube by thermocyphiceffect.üAbove design avoids thermal ageing ofmain insulation and thus CT has very goodthermal stability.üGraded and automised insulation improvesquality and minimises variations
Seismic AspectsüLow Centre of gravityüHeavy cores in bottom tank and will notstress insulatorsüQuartz embedded active partüBottom tank acts as a part of support

• Pressurized air system has been established that leads to a dust free environment in the shopfloor.
• The insulation is dried in ovens at high temperature and vacuum to remove moisture. ASCADA system has been set up for precise control and monitoring of the oven.Efficient drying ensures reduced tan delta and enhances life of product
• After drying CTs are connected to Oil Filling system, where the CTs go through evacuation byapplying vacuum to ensure that there is no moisture or trapped gases in CT. The vacuum levelof 0.15 pascal is checked on individual CTs.
• After oil filling (at 65oC and vacuum ) the CTs are subjected pressurized impregnation at 1.6-1.8 kg/cm2 . Thus ABB CTs experience high vacuum and positive pressure during processwhich proves leak free CTs and suitability of components and robust sealing design.

nThe above assumptionsare no longer validnModern circuit breakers
require less maintenancethan disconnectors withopen contacts
§ Historically, bays were designed to make it possible to isolate thecircuit breaker for maintenance§ The basis was that circuit breakers demanded more
maintenance than disconnectors§ Typical maintenance intervals for old circuit breakers 1-2
years and for disconnectors 4-5 years§ To avoid total outage of the busbar during disconnector
maintenance a second busbar was used
Why are disconnectors required?
DS – User’s Expectation : Reliability with Min.Maintenance
§ Operates smoothly & consistently whencommand is given
§ Consistent Main Circuit Resistance (mVdrop) over life. Less losses.
§ Short time current withstand capacity withsome min. current carrying capability
§ Minimum maintenance during Lifetime§ Good lubricating system§ Synthetic and dry lubrication
§ Retains isolating properties§ Links do not get disturbed§ Permanent adjustments
§ Good seismic withstand capability§ Constructional flexibility to suit various
layouts & spaces in the s/s
Reality & Consequences§ Unable to carry rated
current due to deteriorationof current carrying path
§ Unable to close or open(correctly) due todeterioration of linkagesetc.
§ Failure of interlocks due toauxiliary switch malfunction
§ Failure of electrical circuitsdue to poor enclosure.
§ Failure to withstandseismic forces.
§ Mechanical failures wheninstalled in special layouts

WHY DOES IT HAPPEN ?
§ Jamming of rotary pedestal/linkages
§ Change/shift in the setting of disconnector.
§ Mechanical breakage/damage of contacts and mating parts
§ Hot spots are formed on contact and terminal pads
§ Rusting of cabinets. Jamming of door hinges.
§ Malfunctioning of Aux. Switches
§ All linkages/ bearing assembly require frequent/periodic greasing
§ Setting of limit switches change after some operation and require re-adjustment to have proper operation of disconnector.

Special FeaturesTerminal Head – Weather proof & Robust
TulipContacts
§ Tulip contacts protected from outdoorconditions
§ Graphite and synthetic materialbearings used for life longperformance
§ Synthetic contact grease used forenduring lubrication
Special FeaturesTurn Tables – Maintenance Free Design
§ Turn table bearings protectedfrom environment
§ Two stainless steel bearingsfor reliable rotary movementand reduced friction
§ High temperature stablegrease used for lubrication.Lifetime lubrication. Virtuallyno maintenance
Special FeaturesLinks & End Fittings
§ Several Conventional designs use bushes or no bushes atall. This leads to metal to metal contacts that need regularmaintenance
§ During the operation, three dimensional freedom notachieved and could lead to additional friction anddeformation of parts.
§ This could also lead to galvanic corrosion
Special Features - SolutionLinks – Frictionless joints , Maintenance free
§ Use of insulated rod endspherical stainless steelbearings give§ Protection to galvanic
corrosion§ Three dimensional flexibility
in movement§ Giving reduced friction
through the life
Bearing after 10 years in field
Special FeaturesDrive Type MD80 – Common to SDF & eDB
Ø All mounting nuts & bolts are of noncorrosive material
Ø Aux. Switches are suitable for SCADAapplications and can be changed from NOto NC and vice-versa even at site.
Ø AL. cabinet and powder coated withPolyurethane paints -gives lastingprotection to corrosion.
Ø Stainless steel door hinges does not allowdoor jamming even after many years.
Ø In built safety mech. safety release asstandard feature – main arms cannot rotatemore than 90 degrees in manual ormotorized mode
