Lightning arrester action information recording system and implementation method

Abstract

The invention relates to the technical field of electronics, in particular to a lightning arrester action information recording system and an implementation method. The lightning arrester action information recording system comprises a current sensor, a signal amplification integral module, a signal trigger recording module, a processor, a clock module and a solar power supply circuit; the lightning arrester action information recording system records the action information of the lightning arrester in a manner of driving the bistable relay to act by adopting an electric signal; when the bistable relay is set, the processor is awakened, quits the dormant standby state, records and stores the action information of the lightning arrester, resets the bistable relay, waits for the next actiontriggering of the lightning arrester, and switches to the standby dormant state again, and in the whole recording process, the awakening working time of the processor each time is about one second.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an arrester action information recording system and an implementation method. Background technique [0002] Surge arresters are widely used in power systems. Surge arresters are the most common overvoltage protection devices in power systems. They discharge overvoltage energy through their own actions to protect power facilities from overvoltage. [0003] The arrester action counter is a key accessory facility of the arrester. Its function is to record the number of actions of the arrester, and it is a file to record whether the arrester is "on duty". At present, when investigating overvoltage accidents in power systems, it is necessary to clarify the action of the arrester. Since the arrester action counter widely used at present cannot record the action time of the arrester, whether the arrester operates when the accident occurs becomes a "non-conclusive case". .

At present, when investigating overvoltage accidents in power systems, it is necessary to clarify the action of the arrester. Since the arrester action counter widely used at present cannot record the action time of the arrester, whether the arrester operates when the accident occurs becomes a "non-conclusive case".
