Problems solved by technology

[0002] The power distribution device is an important part of the substation. It is generally composed of switchgear, protective measuring device, busbar device and other equipment. The electrical and mechanical properties of the isolating switch in the electrical equipment will decline after a certain period of time. The safe and reliable operation of the switch requires overhaul and maintenance according to the maintenance cycle of the equipment. During the maintenance process, especially the upper part of the high-rise power distribution device, due to the electrified operation of the adjacent interval equipment, it will cause a lot of inconvenience to the maintenance personnel. At the same time, it has caused great hidden dangers to the safety of maintenance personnel.
