Description

technical field

[0001] The invention relates to a protection device for an isolation baffle of a switch cabinet, in particular to an anti-mis-opening locking device and method for an isolation baffle of a switch cabinet. Background technique

[0002] For the 10~35kV handcart switchgear (including the central cabinet) in operation, when the travel switch, transmission connecting rod, sensor, dehumidifier and other components in the handcart space in the cabinet need to be overhauled, the isolation baffle is required to be reliably closed to ensure Prevent personnel from accidentally opening the isolation baffle and touching live parts, but the current situation is not optimistic, as follows:

[0003] 1. There are safety regulations but the devices that implement the regulations are not comprehensive. In recent years, several cases of personal injury accidents have involved the provisions of 4.5.4 of the "Electricity Safety Work Regulations": "After the handcart switch in the ...
