Embodiment Construction

[0015] A 10kV distribution network line fault prevention method, which is mainly realized through the following steps;

[0016] The first step is to determine the expected cause of the failure; the cause of the failure is: external force damage; tree damage, bird damage; user equipment reasons; equipment defects; cable failure; lightning strikes, pollution;

[0017] The second step is to take preventive measures for different causes of failure; to prevent external damage, tree pests, user equipment reasons, and equipment defects, it is necessary to strengthen the inspection function of user equipment, conduct regular training and communication, implement the equipment management responsibility system, and strictly follow the operation The regulations require equipment inspection and maintenance tests, and strengthen the inspection and inspection of cable lines; for the lines in the polluted area, consider reasonably changing the route to avoid the polluted area, and when a faul...

Abstract

The invention belongs to the electric technology field and particularly relates to a 10kV distribution network line fault prevention method. The method mainly comprises steps that a first step, estimated fault reasons are determined; the fault reasons contain external force damage, tree damage, bird damage, user equipment reasons, equipment defects, cable faults, lightning stroke and pollution; and a second step, prevention measures for different fault reasons are carried out, for the reasons of external force damage, tree damage, bird damage, user equipment reasons and equipment defects, function inspection on the user equipment should be reinforced, regular training and communication are carried out, equipment management responsibility systems are performed, equipment inspection and unkeep test are strictly carried out according to operation rules, inspection and check on a cable line are reinforced, wiring path change can be taken into consideration for a line in a pollution region, the pollution region can be avoided, fault types can be classified after the faults occur, and reasonable and effective measures are adopted for processing.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to a method for preventing faults of 10kV distribution network lines. Background technique [0002] In recent years, on the one hand, due to the rapid economic development in various regions, the living standards of residents have been significantly improved, the scale of power grid construction has also increased correspondingly, and the power grid equipment has increased a lot to meet the demand for electricity; , put forward higher requirements for power reliability, but during the summer peak period, due to lightning damage and lack of management, the tripping of line faults also increased. This patent mainly analyzes tripping faults and puts forward preventive measures to ensure the normal power consumption of residents and the safe and stable operation of the power grid. 10kV distribution lines are an important component of my country's power system and pla...
