ZN85-40.5KV circuit breaker is a high-voltage switchgear introduced by Shaanxi Huadian Electric Co., Ltd. and is widely used in power distribution systems with voltage levels from 35kV to 40.5kV. Its unique vacuum arc extinguishing technology makes this equipment play a vital role in the power system. The following is the working principle of ZN85-40.5KV circuit breaker and its role in power system.
Working Principle:
ZN85-40.5KV circuit breaker adopts vacuum arc extinguishing technology, by which a high-voltage arc is formed rapidly when current passes through the circuit breaker and extinguished in the vacuum environment. As the vacuum environment has very low dielectric loss, the arc extinguishing speed is very fast, which greatly improves the switching capacity of the circuit breaker.
When there is a fault or overload condition in the power system, ZN85 circuit breaker can cut off the fault current in time to prevent the damage of system equipment and ensure the safe and stable operation of the system.
Advantages of ZN85-40.5KV circuit breaker:
Vacuum arc extinguishing: Compared with the traditional gas arc extinguishing circuit breaker, vacuum arc extinguishing technology has higher arc extinguishing efficiency and longer service life.
Long life and low maintenance: ZN85-40.5KV circuit breaker design focuses on low maintenance frequency, adapt to a variety of working conditions, high reliability.
Environmental performance: vacuum arc extinguishing does not produce pollution, in line with modern green environmental protection requirements.
Shaanxi Huadian Electric Co., Ltd. as a leading manufacturer of ZN85-40.5KV circuit breakers, is committed to providing high-performance, low-maintenance, environmentally friendly solutions for the electric power industry, and promoting the stability and security of power systems at home and abroad.If you have any ideas please contact at:
