2019 Good Quality Zjh-12 Series High-Voltage AC Floor Type Metering Box Circuit Breaker
Overview
ZW20-12F/T□-□ series outdoor high-voltage vacuum circuit breakers(hereinafter referred to as circuit breakers) are outdoor distribution equipment with rated voltage of 12kV and three-phase AC of 50Hz.It adopts vacuum arc extinguishing and SF6 gas as insulation medium,and is an improved product of ZW20-12F post vacuum circuit breaker.The gas sealing,explosion-proof and insulation structure technology imported from Japan Toshiba VSP5 is adopted in tje box body,and the sealing performance of the inlet and outlet conduits in also improved,so that the overall sealing performance is excellent,and SF6 gas filled inside does not leak and is not affected by the individual environment;its spring operating mechanism has been miniaturized and optimized in reliability and stability.It adopts direct chain main drive and multi-stage tripping system,and its action reliability and stability are several times higher than those of domestic traditional spring operating machanism.The contact between the shaft and sleeve of the main circuit adopts the structure of adduction and extension bracelet,which has small contact resistance and low temperature rise.Therefore,ZW20-12F outdoor column vacuum circuit breaker is a maintenance-free product and a good product among column circuit breakers.
ZW20-12F also adds overcurrent protection and mechanism spring energy storage indication,and is equipped with aviation socket for secondary electrical connection,which is convenient to combine with intelligent controller.With excellent electrical and mechanical properties,ZW20-12F outdoor post vacuum circuit breaker has been widelyused.It is mainly used to switch on and off the load current and short-circuit current of 10kV power system,and is suitable for protection and control in substations and distribution svstems of industrial andmining enterprises, and is more suitable for places where power grids are frequently operated.This product is matched with the controller and has excellent recloser function,which can meet the requirements of distribution automation system.
