Electric leakage detection system with trip capture function

Abstract

The invention discloses an electric leakage detection system with a trip capture function. The electric leakage detection system comprises a signal detection terminal, a background management platformand a handheld terminal, wherein the signal detection terminal is used for detecting electric leakage current signals of mounting nodes and uploading the detected current signals to the background management platform; the background management platform is used for recording and processing the electric leakage current signals uploaded by the signal detection terminal, generating common electric leakage events, important electric leakage events and trip events, and sending the generated trip events to the handheld terminal so as to immediately remind workers to carry out processing. The electric leakage detection system is capable of detecting the electric leakage conditions of lines and recognizing trip reasons of electric leakage protectors, so as to improve the electricity utilization quality and improve the electricity utilization safety; and through a 4G network, real-time communication is carried out, real-time data can be checked conveniently, and site conditions can be respondedin time, so that the efficiency of the workers can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of testing a power grid leakage detection system, in particular to a leakage detection system with a tripping capture function. Background technique [0002] At present, the penetration rate of residual current action protectors in rural power grids (referred to as leakage protection, which is divided into general protection, branch protection and home protection, forming three levels of protection) exceeds 95%. Fault refusal, overcurrent tripping, leakage tripping, and misoperation tripping occur frequently, seriously affecting the daily electricity consumption of residents. Therefore, the general insurance in general areas has not actually been put into operation, and the method of general insurance outage and forced delivery is adopted to ensure daily power supply. , Obviously, this measure has great security risks. In addition, the general protection and branch protection do not allow trial trips, so it...
