System for remotely monitoring leakage current of lightning arrester on line

Abstract

The invention discloses a system for remotely monitoring the leakage current of a lightning arrester on line, and relates to an improvement on the system for remotely monitoring the leakage current of the lightning arrester on line. The system comprises a data acquisition control device arranged on an acquisition device, and a leakage current signal processing circuit arranged on a near-end integrated automation system, wherein the data acquisition control device comprises a processor, a storage, a clock circuit, an analog-to-digital converter, a signal transceiving circuit and a far-end antenna which are connected; a preset safe current value, a comparison program for comparing the value of the acquired leakage current with the safe current value to control the work of the signal transceiving circuit, a control program for timely sending far-end leakage current data according to a near-end instruction, and a program for timely sending the leakage current data according to time set by the clock circuit are stored in the storage; the leakage current signal processing circuit comprises a signal centralized control transceiving circuit and a near-end antenna; and the signal centralized control transceiving circuit is connected with the integrated automation system. By the system, manual transcription is not needed, and the labor intensity of personnel is reduced.

Description

Technical field [0001] The invention relates to the improvement of a remote online monitoring system for the leakage current of a lightning arrester. Background technique [0002] According to the current unattended situation in the substation, the zinc oxide arrester recorder needs to be manually copied regularly, which causes inconvenience in use and management, and the labor intensity of personnel is extremely high. The safety of the arrester cannot be accurately grasped in time. According to the survey, there is no system on the market that can collect, communicate, store, manage, and share information such as the leakage current of zinc oxide arresters. Summary of the invention [0003] In view of the above problems, the present invention provides a lightning arrester leakage current remote online monitoring system that does not require manual periodic copying, thereby greatly reducing labor intensity, and can ensure that the integrated automation system grasps on-site condit...
