Leakage detecting device for centralized meter box

Abstract

The invention discloses a leakage detecting device for a centralized meter box, which comprises a data collector, a data concentrator, a background main station, a mobile device and at least one leakage detecting clamp. The data collector detects the leakage data of a total incoming line of the centralized meter box, and summarizes the data according to the first preset format of a system and sends the leakage data to the data concentrator. Each leakage detecting clamp detects the leakage data of an outgoing line of a corresponding meter and sends the leakage data to the data concentrator, sothat the data concentrator summarizes the leakage data sent by each leakage detecting clamp according to the second preset format of the system, and uploads the leakage data and the leakage data sentby the data collector to the background main station and the mobile device. The data concentrator is further configured to compare, according to a leakage scheme preset by the system, the leakage datasent by the leakage detecting clamp and the data collector to obtain the leakage condition, and upload the leakage condition to the background main station and the mobile device. The leakage detecting device can flexibly detect the leakage condition of the centralized meter box.

Description

technical field [0001] The invention relates to the technical field of electric leakage detection, in particular to an electric leakage detection device for a centralized meter box. Background technique [0002] At present, in the low-voltage 380 / 220V three-phase four-system power supply system, each branch line and residential households are generally equipped with leakage protection switches. However, due to the aging of the circuit or the private pulling of the circuit, leakage phenomenon often occurs, the leakage protection switch often trips, and the fault point of leakage current cannot be eliminated in time and accurately, which directly affects their own household appliances; The switch is removed and replaced with a knife switch or an air switch, but in this way, the leakage protection measures are lost, which can easily cause electric shock casualties and fire accidents. At the same time, when the leakage current reaches a certain value, it will cause the upper lev...
