There are 3 common faults of distribution network distribution lines, namely transformer fault, ground fault and short circuit fault. These faults can have a serious impact on the proper operation of the distribution line, thereby preventing the proper delivery of power resources. Common reasons for causing the distribution network distribution line fault include three aspects of natural factors, human factors and equipment factors, and the natural factors are that the distribution network distribution line is exposed outdoors, and inevitably suffers from extreme natural climate influences, such as thunder and lightning, rainstorm and the like, so that the line is short-circuited, and a ground fault is caused. The human factors are that the environment cannot be checked, the operation cannot be strictly carried out according to the standard, and the elimination of the hidden trouble of the fault is not comprehensive enough. The equipment factor is mainly that the equipment quality is unqualified and the operation requirement of the system cannot be met.

In order to solve the ground fault and the short-circuit fault of the distribution network distribution line, the safety and the stability of the distribution network line are improved, and the distribution line is subjected to insulation protection by a power grid company. The insulation protection is divided into full insulation protection and partial insulation protection. Full insulation protection means that insulation protection measures are adopted for the whole line, and the insulation protection measures comprise large-scale use of insulated wires in an urban power distribution network system. The local insulation protection means that insulation protection measures are adopted at certain parts or certain parts of the circuit, and an insulation sheath can be adopted to perform local protection pertinently or an overhead insulated conductor is adopted partially.
