Description

Quick connection device for power distribution non-stop operation

technical field

The invention relates to the technical field of electric power auxiliary equipment, in particular to a quick connection device for power distribution and non-stop operation.

Background technique

During the operation of the conventional power system, when the power distribution network is cut off due to failure or maintenance, when the staff arrives at the scene, they need to pull the switch of the low-voltage incoming line and high-voltage incoming line, and the grounding wire must be hung up, so that the bypass cable can be connected. busbar. During the whole access process, the bypass cable should be put into the user power distribution room first, the access point should be searched, and then the cable should be connected, which takes a long time and reduces work efficiency. In addition, the bypass cable is thick and heavy. When the access to the busbar is blocked with bolts, due to the small space for fixing the position, the lock is not firm, resulting in increased contact resistance and reduced access reliability. At the same time, the connection process is fixed with a large wrench, which is easy to accidentally touch and misoperate other electrical equipment, which brings potential safety hazards.

When the power supply is guaranteed, in order to quickly restore the power supply, it is necessary to cut off the power of the busbar in advance and then connect it with bolts; after the power supply is completed, cut off the power to the busbar again and remove the bypass cable. A longer time impact will cause greater economic losses.
