Abstract

The invention relates to a lightning protection method of a 10kv power distribution circuit. Through applying a thunder and lightning positioning system and a counter on the power distribution circuit, under the condition that the normal safety operation of the normal power distribution circuit is not influenced, the action situation of a discharge counter is observed after the thunderstorm each time, and parameters and atlas displayed by the lightning position system are observed again, so that the thunder and lightning overvoltage properties can be judged, thus corresponding preventive measures are worked out purposefully, and the accident that the power distribution circuit and electrical equipment are frequently damaged because of overvoltage is eradicated; and the system is simple to mount, low in cost and reliable in operation.

Description

technical field

[0001] The invention relates to a lightning protection method, in particular to a lightning protection method for a 10kv power distribution line, and belongs to the field of electric power applications. Background technique

[0002] With economic development, the number and length of 10kV lines are increasing, and the types and applications of arresters are also increasing. However, accidents caused by overvoltage of distribution lines and electrical equipment are more frequent. Summarize the main problems in the following three aspects: 1. How to verify whether the distribution line has suffered lightning overvoltage. 2. How to determine the form of lightning overvoltage (direct lightning strike, induction lightning, counterattack lightning). 3. How to verify whether the protection performance of the arrester is excellent. Contents of the invention

[0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a lightnin...
