Description

Technical Field

[0001] The utility model relates to the technical field of overhead line insulated wire drainage, in particular to an overhead line insulated wire drainage device. Background Art

[0002] The drainage line technology is mainly used during equipment maintenance and replacement. Its technical principle is to use the drainage line bypass live working technology, and the drainage line will temporarily short-circuit the two-phase side of the equipment to be repaired, forming a current loop outside the equipment to be replaced through the equipment power side - drainage line - equipment load side. This forms a stable current loop in parallel with the equipment, so that the charge of the replaced equipment is completely transferred to the drainage line parallel loop. During this live working process, there is no need to cut off the load carried by the equipment, which can ensure the continuous and stable power supply of the power grid system.

[0003] In view of this, Chinese Patent No. CN205070360U proposes an overhead line insulated conductor drainage device.
