OPERATION ENVIRONMENTATbS automatic changing-over isolation switch can work

reliably under the following conditions:

- Height above sea level does not exceed 2,000m;

- Ambient temperature is not higher than 40OC and not lower than -5OC.

- Relative humidity is not larger than 95%;

- No expiosive dangerous medium environment;

- No rain and snow attack environment;

Note: if the load isolation switch is expected to be used in the condition that the ambient temperature is higher than +40OC or is lower than -5OC ~ -45OC, customers should inform to the manufactory

MODEL & MEANING

PRODUCT OUTLINEATbS automatic changing-over switch integrates switch and logic control. Thus it is not necessary to provide external cont roller.

This truly electrome mechanical intergrated automatic change-over switch has the following functions such as voltage detection, frequency detection, communication interface, electrical and mechanical inter interlocking etc., So, automatic control, electrical remote control and emergency manual control can be performed.

The operation is carried out through the logic control board, which gives various commands to control the motor and gearbox. The motor drives the accelerator which can take swich spring power accumulating and instantaneous release, swiftly turns making and breaking the circuit or makes circuit switching. The visible operation status can help you to perform safe separation, increasing extremely the various electrical and mechanical performance.

The shell of switch ATbS is made of metal. Being small and compack, while the shell of switch ATbS is made of different materials: it is control section made of metal, but the switching section is made of glassfibre unsaturated polyester resin, having stronger dielectric property and protective capa-bility as well as safe operation performance.

This kind of switch is suitable for the automatic change-over of the main power source and the secondary power source of the power supply system or the automatic change-over and safe separation of the 2 sets of load-equipment.

This kind of switch has a beautiful, novel and simple structure, a small volume but complete functions, being the best choice among congeneric of products.

CONFORM STANDARDATbS series Automatic change-over switch complies With The Following Standards:

International Standard:

IEC60947-1(1998) ( Low-voltage switchgear and controlgear,part one: General Rules)

IEC 6094-3(1999)( Low-voltage switchgear and controlgear, switches, disconnectors, switch-disconnectors and fuse-con-bination units)

IEC60947-6(1999) (Low-voltage switch equipment and control equipment multi-function-switch automatic change-over switch electrical device)

PRODUCT USAGEATbS series Automatic change-over switch mainly suitable for distribution or electromotor network, which under AC 50Hz, rated voltage 380V, rated voltage DC220V, rated current 125-3200A, main power and standby power or mutual standby power change over system or city power and generator group overload switch-over. At the same time, it can operated under un-frequency On and Off circuit act as disconnector.

TECHNICAL PARAMETER

ATS CONTROLLER ATbS C53

The powerful Microprocessor contained within the ATbS C53 controller allows for precision voltage (2-way 3-phase/single phase) measuring and make accurate judgment on abnormal voltage (power lost, over/under voltage, over/under frequency, loss of phase, phase sequence wrong) and control ATS to transfer after the delay has expired. This controller is suitable for NO Breaking ATS and ONE Breaking ATS. When #1 power is abnormal, the controller will send signal to start genset after the “#1 abnormal delay” has expired. “Three remote” (remote control, remote measurement and remote communication) Function can be implemented with the help of LINK communi-cation port.
