Zn85 вътрешно напрежение VCB

● Structural characteristics

ZN85 Indoor high voltage vcb and operating mechanism are arranged up and down, which effectively reduces the circuit breaker's Depth. The three-phase arc extinguish chamber and that connecte charged body are separated by three independent epoxy resin insulating cylinder, To form a composite insulation structure, ZN85 Indoor high voltage vcb meets the requirements of air distance and climbing distance under normal operating conditions. And effectively reduce its own volume. Vacuum interrupter and dynamic and static of main electric circuit The conductive connection is installed in the insulating cylinder, so that the phase spacing is only 300 mm. Electrical connection of main circuit All adopt fixed connection, which has high reliability. The insulating cylinder is installed in the circuit breaker frame. Above the shelf. ZN85 Indoor high voltage vcb mechanism has simple design, better output curve and performance. The characteristics and requirements of 40.5kV vacuum circuit breakers are applicable. The overall layout is reasonable, beautiful and concise. Small size, flexible operation, long service life, convenient maintenance and maintenance-free mechanism. The circuit breaker is suitable for frequent operation, various occasions and places with harsh operating conditions.
