A lightning strike counting device

Abstract

The invention provides a lightning strike counting device. An open current transformer is used for detecting the current on a grounding wire of a lightning arrester. When lightning strikes, the open current transformer can sense the current flowing, generates a sensing current, and transmits the current to a first controller. The first controller controls that the number of times of lightning displayed on a first display screen to be added by one, thereby realizing the lightning strike counting function. Because of the open current transformer, mounting or dismounting becomes convenient; and with a testing line, the lightning striking situation is simulated by leading the power to the test line, thereby determining whether the lightning strike counting device works normally. Therefore, thenormal operation of the power system is ensured; and the basis is provided for fault analysis of the power system.

Description

technical field [0001] The invention relates to the technical field of lightning protection for power distribution lines, in particular to a lightning strike counting device. Background technique [0002] Lightning arrester is an important device to protect power equipment. When a lightning strike occurs, the lightning current can be introduced into the ground to prevent the power system from being damaged. In order to grasp the lightning strike to ensure the normal operation of the power system, a lightning strike counter is designed. Used to count the number of lightning strikes. [0003] The existing lightning strike counters are generally fixed on the grounding wire of the lightning arrester, and are used to collect whether there is current passing through the grounding wire to judge whether a lightning strike occurs. When the lightning strike counter fails, it needs to be disassembled for maintenance. The disassembly is difficult and reduces Maintenance efficiency is r...

[0003] The existing lightning strike counters are generally fixed on the grounding wire of the lightning arrester, and are used to collect whether there is current passing through the grounding wire to judge whether a lightning strike occurs. When the lightning strike counter fails, it needs to be disassembled for maintenance. The disassembly is difficult and reduces Maintenance efficiency is reduced, and it is often difficult for staff to judge whether the lightning strike counter can work normally, and it is impossible to guarantee the normal operation of the power system
