Abstract

The invention discloses a rapidly-starting switch cabinet. The switch cabinet comprises a cabinet body. The cabinet body is connected with a vacuumizing pump and an air charging pump. The cabinet body is provided with a detection hole and is externally connected with a detection protection device via the detection hole. The detection protection device comprises a detection unit and a control unit. The detection unit detects gas concentration in the switch cabinet and outputs sensing signals. The control unit is coupled to the detection unit and controls the work timing sequence of the vacuumizing pump and the air charging pump according the sensing signals. The objective of the invention is to detect air concentration of protection atmosphere in the switch cabinet via the detection protection device and automatically perform vacuumization and nitrogen charging operation in the switch cabinet according to the gas concentration, and automation efficiency of production is increased.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a quick start switch cabinet. Background technique [0002] Indoor AC high-voltage gas-insulated metal-enclosed switchgear (hereinafter referred to as "inflatable cabinet") is a new generation of switchgear. The main switch can use either a permanent magnet mechanism vacuum circuit breaker or a spring mechanism vacuum circuit breaker. The whole cabinet adopts air insulation. Combined with a SF6 gas compartment, it is both compact and expandable for distribution automation. The inflatable cabinet has the characteristics of compact structure, flexible operation, and reliable interlocking. It can provide satisfactory technical solutions for various applications (especially places with harsh environments) and different user requirements. The adoption of sensor technology and the latest protective relay, coupled with advanced technical performance and light and flexible assem...
