BGZ6-40.5 (ZW32-40.5 F (40.5 C) ZW32 -) type outdoor column on AC high voltage vacuum circuit breaker (hereinafter referred to as 35 KV column on the circuit breaker) is my company independent research and development of a new product, the circuit breaker is a set of vacuum circuit breaker, controller, separating section, four big functions of intelligent multifunctional intelligent protection device products, main configuration by the boundary between vacuum circuit breaker ontology, MGK16 controller, the external voltage transformer (note: Optional in the distribution network automation ring line of bilateral PT) products are mainly applied in 35 KV city of ring network, rural power distribution network overhead line segment isolating switch, contact switch, or the transition of city network site to overhead lines and cable joint boundary control and protection, may apply ring line load allocation automatic switching device, in the big user power supply branch circuit can be used as separating switch (commonly known as watchdog), feeder overhead distribution network and used as the boundary between the breaker section, boundary between vacuum circuit breaker with remote management mode, protection control function and communication function. It can reliably judge and detect the zero-sequence current and phase-to-phase short-circuit fault current within the boundary of milliamps, and realize the automatic removal of single-phase ground fault and phase-to-phase short-circuit fault.


BGZ6-40.5 35KV intelligent outdoor column high voltage vacuum circuit breaker

☆ The use of vacuum arc extinguishing, breaking ability, mechanical life up to 10,000 times

☆ Simple structure, maintenance - free, long maintenance cycle

☆ Good insulation performance, anti-pollution ability, no fire and explosion risk

☆ With CT32 (BGZ6) type electric spring operating mechanism, mechanical performance reliable

☆ Equipped with a two-phase or three-phase current transformer, the precise level of 0.2s can achieve protection and measurement

☆ Switch integral seal moistureproof anticorrosion performance is good

☆ Product structure lightweight and 35KV ZW7 type outdoor high voltage vacuum circuit breaker compared with the volume reduced by 2/3;Weight loss of more than 65%; And the intelligent protection function can be automatically protected without connecting the backup microcomputer

☆ Reduced floor area, there is no need to enclosure the construction of a special small switch substation, directly put the switch on the overhead wire tower installation, ☆ Reduce the construction workload small volume light weight without additional installation foundation only need to lift fixed on the overhead wire tower can be apply to the environment

◆ Use environmental conditions

☆ Ambient temperature: upper limit +40℃, lower limit -40℃;

☆ Air relative humidity: daily average is no more than 95%, monthly average is no more than 90%;

☆ Altitude ≤500m(For the high altitude area, please increase the corresponding power pulling distance;

☆ the wind pressure is not more than 700Pa (the wind speed is 34m/s for a certain day);

☆ Pollution level: Level IV (pulling power specific distance ≥31mm/KV)

☆ Ice thickness ≤10 mm

☆ Earthquake intensity ≤8 degrees

☆ Installation site: there should be no fire, explosion danger, serious pollution, chemical corrosion and violent vibration, etc
