What is the outdoor vacuum circuit breaker ?
Outdoor vacuum circuit breaker is a key equipment used in outdoor power systems. It is mainly used to quickly cut off the faulty part when a fault occurs in the power system, thereby protecting the safe operation of the entire power system. It consists of an insulating cover, a vacuum interrupter, a contact system and an operating mechanism.
Features and advantages
Good maintenance-free: Since the vacuum interrupter adopts a closed structure, it can maintain a high vacuum degree for a long time and does not require regular inflation and maintenance.
Long life: The service life of vacuum circuit breakers is usually longer than that of air circuit breakers, and they can maintain reliable operating performance for a longer time.
Safe and reliable: The vacuum circuit breaker has a strong arc extinguishing ability and can quickly cut off the faulty circuit to protect the safe operation of the power system.
Application field
Outdoor vacuum circuit breakers are widely used in outdoor power systems such as distribution networks and substations, especially in urban and rural power grid transformation and upgrading projects. It can be used not only for switches at both ends, but also for short-circuit protection, overload protection and other protection devices. ZW32-12 Outdoor Vacuum Circuit Breaker produced by Shaanxi West power Tongzhong Electric Co., Ltd.It has several structural features:
1. The integrally formed casing can ensure good air tightness. The isolating knife switch can be configured with an obvious disconnection point, which is convenient and safe to maintain.
2. The outdoor isolating switch and circuit breaker can be installed to form an integrated system.
3. An external electronic PT can be installed to make the circuit breaker have an operating power supply and anti-surge current, overcurrent protection, and local remote control functions.
4. A lightning arrester can be installed. The lightning arrester can be installed on the power supply side or load side according to user needs.
