Description
technical field [0001] The invention relates to the technical field of electric safety tools, in particular to a fully enclosed isolation operation switch cabinet. Background technique [0002] At present, when the high-voltage switchgear fails, the power is usually cut off first and then operated for safety. Since the door of the switchgear is opened during operation, the live mechanism and the operator cannot be well isolated, so it cannot be charged Operation, large-scale power outages cause relatively large negative impacts. Contents of the invention [0003] The purpose of the present invention is to provide a fully enclosed switchgear for isolated operation in order to solve the problem that the current switchgear cannot be operated with electricity and large-scale power outages cause relatively large negative effects. [0004] The specific solution of the present invention is: a fully enclosed isolation operation switch cabinet, including a cabinet body, an actuato...
