Technical Field
The invention relates to the field of switch cabinets, in particular to a switch cabinet with relatively moving isolation.
Background
As is well known, a load switch or a suspension type disconnecting switch is installed in a conventional medium voltage switchgear, and in order to isolate a static contact and a live part of the load switch or the suspension type disconnecting switch during an overhaul process of the switchgear, so as to reliably isolate a part requiring power failure from the live part, measures generally taken in the prior art are as follows: after the switchgear is opened, the insulation barrier is then inserted manually by the service personnel directly into the switch isolation interruption. However, since this insertion is performed by the equipment maintenance personnel manually touching the insulating partition after the equipment is opened, it is necessary to bring a certain safety hazard to the equipment maintenance personnel.
Therefore, how to ensure the personal safety of the equipment maintenance personnel in the operation process is a problem which needs to be solved urgently in the field.
