High-voltage switch cabinet with protection function and using method thereof

Abstract

The invention discloses a high-voltage switch cabinet with a protection function and a using method of the high-voltage switch cabinet. The switch cabinet comprises a switch cabinet main body, a rotating handle, a connecting rod driving piece, a bolt, a bolt seat, a first guide rod, a roller, a second guide rod, a compression spring, a switch control piece and a roller limiting piece. A first cabinet door and a second cabinet door are installed on one side of the switch cabinet body through hinges. Cabinet door handles are fixed to the side face of the first cabinet door and the side face of the second cabinet door correspondingly. By rotating the rotating handle on the first cabinet door, the connecting rod driving piece is driven to rotate, the bolt is controlled to enter and exit from the bolt seat; the locking and unlocking of the switch cabinet door are realized; meanwhile, the unlocking is realized; the circuit switch is switched off through the cooperation of the first guide rod, the second guide rod and the roller, and the switch control part is driven by the compression spring and the second guide rod to switch on the circuit switch during locking, so that the risk of personnel electric shock caused by neglecting the closing operation of a circuit when a maintainer overhauls the interior of the switch cabinet is avoided, and the equipment safety and personnel safety are protected.

Description

technical field [0001] The invention relates to a switchgear structure, in particular to a high-voltage switchgear with protection function and its use method. Background technique [0002] The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switchgear mainly include circuit breakers, isolating switches, load switches, It is composed of operating mechanism, transformer and various protection devices. [0003] In the prior art, the maintenance personnel need to open the cabinet door and then disconnect the circuit switch before performing maintenance. The maintenance personnel sometimes forget to disconnect the circuit or make a wrong operation, which may cause electric shock hazards and major safety accidents. It is urgent to solve this situation. Protect. Therefore, we propose a high-voltage switc...
