Problems solved by technology

At this time, the live contacts in the high-voltage switchgear are exposed. Although the high-voltage switchgear is maintained with an anti-shock isolation baffle, the operators have been protected, but several accident cases show that artificially opening the high-voltage switchgear to prevent electric shock Isolation baffles, accidentally touching exposed live contacts, often lead to personal accidents, the industry urgently needs an anti-shock fixing device for isolation baffles of high-voltage switchgear

Abstract

The invention discloses an electric shock prevention fixing device for isolation baffles of a high-voltage switch cabinet. The electric shock prevention fixing device comprises an upper clamping part, a lower clamping part and a locking pin. The lower portion of the upper clamping part is provided with a first through hole, the lower portion of the lower clamping part is provided with a second through hole, and the locking pin penetrates through the first through hole and the second through hole to fix the upper clamping part to the lower clamping part. The electric shock prevention fixing device has the advantages that the upper electric shock prevention isolation baffle and the lower electric shock prevention isolation baffle are fixed by the electric shock prevention fixing device for the isolation baffles so as to be locked and fixed in the working process and prevented from being manually opened under general conditions, so that personal electric shocks are effectively prevented, and urgent requirements of the technical field are met. In addition, the electric shock prevention fixing device is easy to manufacture, high in operability and suitable for being applied and popularized as an effective safety facility in the technical field.

Description

technical field [0001] The invention relates to the technical field of electric power equipment; in particular, it relates to an electric shock-proof fixing device for an isolation baffle of a high-voltage switch cabinet. Background technique [0002] During the operation and maintenance of high-voltage switchgear, it is often necessary to open the high-voltage switchgear to maintain the equipment in the high-voltage switchgear. At this time, the live contacts in the high-voltage switchgear are exposed. Although the high-voltage switchgear is maintained with an anti-shock isolation baffle, the operators have been protected, but several accident cases show that artificially opening the high-voltage switchgear to prevent electric shock If the isolation baffle accidentally touches the exposed live contact, it will often lead to personal accidents. The industry urgently needs an anti-shock fixing device for the isolation baffle of the high-voltage switchgear. Contents of t...
