Outdoor vacuum circuit breaker SZRZ7-40.5 Product details: SZRZ7-40.5 outdoor high voltage vacuum circuit breaker for AC 50Hz, voltage 40.5KV three-phase power system, as breaking, closing load current, overload current and short circuit current purposes. Using the latest estimate flux and speed arithmetic processing technology to achieve high-performance speed sensorless vector control; self-learning function parameters, static parameters of self-learning, easy to operate; built-in Modbus protocol, convenient automation systems integration; indoor vacuum circuit breaker SZRN85-40.5 Product Details: inside SZRN85-40.5 / T2000-31.5 type indoor high voltage vacuum circuit breakers for three-phase AC 50Hz, rated voltage 40.5KV dpac industrial power system, for industrial and mining enterprises, power plants and substations as division and load current, overload current, fault current purposes. The circuit breaker operating mechanism up and down with the arrangement, effectively reducing the depth of the circuit breaker. Three-phase arc chamber and linked by the three independent body charged epoxy insulating cylinder relative isolation RE industrial, constitute a composite structure of industrial products manufacturers, circuit breakers meet the air under normal operating conditions, distance and creepage distance requirements, and effective reduces the volume of the circuit breaker. Leading electrical circuit vacuum interrupter and movement conductive coupling mounted in the insulating cylinder Industrial, the phase pitch of only 300mm. All main circuit electrical connections fixed connections, with high reliability. Insulating cylinder mounted above the circuit breaker frame. 3AV3 spring operating mechanism for such a new circuit breaker designed, installed in the circuit breaker frame, the upper and lower its structural features more suitable layout of the circuit breaker, breaker and become an integral part of the overall structure. Mechanical design is simple, the output curve and performance more suited to the characteristics and requirements 40.5KV vacuum circuit breaker. The overall layout is reasonable, beautiful, simple. Compact, flexible operation, with electrical performance, reliable, long life, easy maintenance, body maintenance-free features. The circuit breakers for frequent operation and a variety of occasions and operating conditions are harsh places. auo industrial, industrial, electromechanical provided by the Henan Xi Xi promise Connaught Electrical and Mechanical Equipment Co., Henan Xi Connaught Electrical Equipment Co.
