Electric leakage real-time monitoring system

Abstract

An electric leakage real-time monitoring system comprises a mobile detection terminal, a concentrator and a remote server which are in wireless communication connection. The mobile detection terminal is arranged at a power supply branch switch and comprises a transverse cylindrical shell, and the control unit is in signal connection with the current detection unit and the wireless communication unit; the system has the beneficial effects that the structural design is reasonable, after the upper shell and the lower shell are buckled, a cable can be clamped, and threading openings in the two ends can be plugged through wire clamping plugs, so that the whole device is fixed to the cable, the device is prevented from sliding on the cable, and safety and reliability are improved; solar power supply is adopted, power supply efficiency is improved, heat dissipation effect is good, and detection accuracy and efficiency are high.

Description

technical field [0001] The invention relates to a leakage real-time monitoring system. Background technique [0002] At present, in the low-voltage 380 / 220V three-phase four-wire power supply system, all branch lines and residential households are generally equipped with leakage protectors. Due to the aging of the lines, leakage protectors may be triggered by leakage, and the fault point cannot be timely and accurate. Excluded, directly affecting their own household electricity, many households removed the leakage protector and replaced it with a knife switch or an air switch. In this way, when the leakage current reaches a certain value, the leakage protector at the upper level will trip, and even the secondary main switch of the transformer will trip. Contents of the invention [0003] In order to solve the above technical deficiencies, the present invention provides a real-time leakage monitoring system, which can detect the leakage current scheme online in real time, ...
