[0001] The invention relates to electric power equipment for distribution network, in particular to electric power equipment suitable for conducting drainage and grounding in emergency repair work without power outage. Background Art

[0002] When inspecting and repairing power distribution rooms, ring network cabinets and other power places, State Grid Corporation of China has put forward the goal of "no power outage and zero perception". To achieve the goal of no power outage and zero perception, it is necessary to bypass the peripheral distribution network in a live state. At present, to achieve live bypass operations, it is necessary to manually climb up to perform specific work such as cable stripping and hanging drainage lines. There are major safety hazards for operators to come into close contact with live cables.

[0003] When encountering some parts where grounding rings are installed, the inventors have tried to use grounding rings to achieve drainage. A certain effect was achieved, but there are the following disadvantages in using existing grounding rings for "drainage": First, the number of grounding rings installed is small, which does not meet the requirements of this solution's search and fault repair work, that is, there may not be a grounding ring at the required position; second, the body of the grounding ring in the prior art is a circle of rigid conductors with equal cross-section.
