Problems solved by technology

[0002] High voltage is an important feature of the power system. With the rapid development of high-voltage transmission technology, it brings huge safety hazards to the safety of operation and maintenance personnel.
According to incomplete statistics, as many as 90% of the high-voltage live faults are caused by the misoperation of maintenance personnel.
Maintenance personnel rashly carry out maintenance and other operations when they mistakenly think that the power is off, causing the circuit to burn out, causing casualties in severe cases, and bringing huge safety hazards to the normal high-voltage power system
[0003] Usually, when the switch cabinet partition valve is closed, it can block the live parts in the switch cabinet, but the currently used switch cabinet partition valve lacks a fixing device when the switch cabinet partition valve is closed, and the valve may be opened with a little external force, losing the protective effect
