It is composed of overhead lines, cables, towers, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities, and plays an important role in distributing electric energy in the power grid.

[0003] According to an auxiliary device for distribution network fault inspection and maintenance disclosed in Chinese patent CN217956545U, the wires are positioned by four wheels, and blades are pressed into the inner skin of the wires to push the pressing block. The wheels and blades roll on the wires, and the blades cut the outer skin of the wires, dividing the outer skin at the end of the wires into two halves, making it easy to remove the outer skin, thereby solving the problem of inconvenience in stripping the wires during the existing distribution network fault inspection and maintenance.

[0004] Before using the above device, the wire is controlled to pass through the casing and then the surface is cut. However, when the cutting length of the surface to be cut is too long, the casing needs to be moved to a certain position before it can be used, and the cutting position cannot be directly located. For this reason, we provide an auxiliary device for distribution network fault inspection and maintenance. Utility Model Content
