Intelligent electric leakage detection device based on low-voltage power distribution network

Abstract

The invention discloses an intelligent electric leakage detection device based on a low-voltage power distribution network, and the device comprises a voltage collection module which is used for collecting the live wire voltage of a leakage protector behind a meter; the current acquisition module is used for acquiring current of a live wire and a zero wire of the meter rear leakage protector; the host is connected with the voltage acquisition module and the current acquisition module and is used for processing and sending the acquired voltage and current information; and the antenna is connected with the host and is used for connecting the Internet. Whether the load side of each meter rear leakage protector has voltage or not can be detected in real time, and whether power failure occurs or not is judged; whether the live line and the zero line of the load side of each meter rear leakage protector have leakage current is detected, so that first-aid repair personnel can judge fault positions and power failure reasons conveniently, loss caused by power failure is avoided, and the efficiency of operation and maintenance is improved.

Description

Technical field [0001] The present invention relates to the field of leakage detection, and more particularly to a smart leakage detecting device based on a low voltage distribution network. Background technique [0002] When short-circuit or leakage occurs in the home, the leakage protector will generally trip, but the list of leakage protector after the individual cases, the total switch of the box, which causes the entire table box without electricity, power supply company repair personnel After that, it cannot be determined which the fault in the family of the residents has a total switch cross-level trip, there is only to temporarily switch the total switch of the table box. After a while, the household appliance or broken leakage of the residents' homes can be caused again. The total switch of the table box is closed, but frequently unable to find the reason, it will cause resident complaints. Inventive content [0003] In the case of the prior art, the problem of stopping...

Problems solved by technology

[0003] In view of the problem in the prior art that the cause of the power outage cannot be determined after the main switch of the meter box is tripped, the present invention provides an intelligent leakage detection device based on the low-voltage distribution network, which detects in real time whether there is voltage on the load side of the leakage protector behind each meter. Determine whether there is a power failure; detect whether there is leakage current on the live wire and neutral wire on the load side of the leakage protector behind each meter, so that the emergency repair personnel can judge the fault location and the cause of the power failure
