Mechatronics counter for line arrester

Abstract

The present invention provides a mechatronics counter for a line arrester. The mechatronics counter for the line arrester comprises a mechanical counter; a counting circuit connected with the line arrester is installed in the mechanical counter and includes a rectifier, and the rectifier is connected with a relay; the counting circuit is also connected with an electronic counter, and the electronic counter arranged in the mechanical counter includes a lightning stroke signal acquisition module, a data storage module, a data transmission module, a counting power supply module, a clock module and a counting single chip microcomputer system; the lightning stroke signal acquisition module is configured to record the action times of the relay after being connected with the rectifier; and the data transmission module is configured to send data and is in wireless connection with a data receiving device. According to the mechatronics counter for a line arrester, the action times of lightning stroke may be accurately recorded through a mechanical counter, and corresponding action times and actuation time may be accurately recorded through an electronic counter and may be transferred for a long distance to a receiving device.

Description

technical field [0001] The invention relates to the technical field of lightning arresters, in particular to a counter for electromechanical integrated line lightning arresters which records the number and time of lightning strikes. Background technique [0002] Lightning strike is a major natural disaster in the power system. The accidents caused by lightning strike account for half of the total accidents. It has a great impact on the power system and seriously affects the safety and reliability of the transmission line operation. Operation experience shows that the line arrester can effectively improve the power transmission line. The lightning resistance level of the line is one of the most effective means of lightning protection for the current line. At present, a large number of line arresters are used for AC transmission lines from 10kV to 500kV, and most of the arresters are located in wild mountainous areas or uninhabited areas, and the distance between them is very s...

[0002] Lightning strike is a major natural disaster in the power system. The accidents caused by lightning strike account for half of the total accidents. It has a great impact on the power system and seriously affects the safety and reliability of the transmission line operation. Operation experience shows that the line arrester can effectively improve the power transmission line. The lightning resistance level of the line is one of the most effective means of lightning protection for the current line. At present, a large number of line arresters are used for AC transmission lines from 10kV to 500kV, and most of the arresters are located in wild mountainous areas or uninhabited areas, and the distance between them is very small. Far away, it is very inconvenient to realize the operation times of mechanical counters manually through telescopes or climbing towers. Doing a data statistics not only consumes huge manpower and material resources, but also considers the weather conditions and other natural environmental factors at that time. It is impossible to accurately monitor and analyze the
