High-voltage switchgear vacuum circuit breaker trolley closed in the test position, the car circuit breaker can not enter the working position, the switchgear is an electrical equipment, outside the first into the main control switch cabinet, and then enter the sub-control switch, the shunt Set according to their needs. Such as instruments, automatic control, motor magnetic switches, all kinds of AC contactor, and some also set high voltage room and low voltage room switchgear, with high voltage bus, such as power plants, and some also have to protect the main equipment of the low week Loaded.
Low Voltage Distribution Cabinet is a new type of low voltage distribution cabinet designed according to the requirements of the Ministry of Energy, the majority of power users and design departments, and designed according to the principle of safety, economy, reasonableness and reliability. The products have the advantages of high breaking capacity and good dynamic and thermal stability , The electric scheme is flexible, the combination is convenient, the series is sexual, the practicality is strong, the structure is novel, the protection grade is higher etc. It can be used as the replacement product of the low-voltage switchgear.
High voltage switchgear grounding knife in the position, the car circuit breaker can not be closing, high voltage switchgear vacuum circuit breakers in the closing work, the cabinet door with ground knife on the mechanical and cabinet door lock, high voltage switch Vacuum circuit breakers inside the cabinet closed at work, combined ground knife can not be put into the high voltage switchgear vacuum circuit breakers in the work closing operation, can not exit the working position of the car circuit breaker.
