Zw20-12 Pole-Mounted Sf6 (LBS) Air Electric Vacuum Auto Recloser Circuit Breakers Interrupter Load Break Switch
General


Zw20-12F series outdoor high-voltage AC boundary vacuum circuit breaker (hereinafter referred to as "boundary circuit breaker") is an outdoor high-voltage switch with three-phase AC 50Hz and a rated voltage of 12kV. It is mainly composed of a vacuum circuit breaker body, distribution automation feeder terminal, voltage transformer, control cable, etc. The circuit breaker body is equipped with a vacuum arc extinguishing chamber, a current transformer, a zero-sequence current transformer, and other components.

The boundary breaker has a remote management mode, and the protection control function and communication function can be reliably judged. The detection boundary is used for control and protection in substations, industrial and mining enterprises, and urban and rural power grids. It is especially suitable for places requiring frequent operation and urban milliampere zero sequence current and interphase fault short circuit current, so as to automatically remove single-phase ground fault and interphase short circuit fault.

The boundary breaker adopts a vacuum arc extinguishing and SF6 gas-insulated box, which adopts foreign advanced gas sealing and is explosion-proof. The overall sealing performance of insulation structure technology is excellent. Its spring operating mechanism adopts a miniaturized design, which has excellent performance and is far more reliable than the domestic traditional spring operating mechanism.

The boundary breaker shall comply with the technical standards such as High Voltage AC Circuit Breaker (GB/T1984214), High Voltage Clearing Circuit Breaker (DL/T402-2016), Technical Conditions for Ordering 12kV 40.5kV High Voltage Vacuum Circuit Breaker (DL/T403-2000) and Remote Terminal of Distribution Automation System (DL/T721-2013).
