Structure introduction
:
The switch cabinet body is welded with high-quality angle steel. The circuit breaker room is located in the middle (lower) part of the cabinet body. Installation, Easy to debug and maintain. It is equipped with a standard circuit breaker and is equipped with a pressure release channel to ensure personal safety. An advanced and reliable rotary isolation switch is used to safely enter the circuit breaker room for inspection and maintenance of the whole cabinet when the main busbar is powered. The protection level equipment is equipped with a reliable and fully functional The mandatory mechanical locking device is simple and effective to meet the "five preventions" requirements. It has a reliable grounding system. There is an observation window on the door, which can clearly observe the working status of the components in the cabinet. The operating mechanism locking adopts the locking mechanism used in the same cabinet, which is simple, reliable, convenient and practical. The incoming and outgoing cables are lower than the front of the cabinet bottom, making it convenient for users to connect.
