Power distribution network fault detection voltage transformation testing device

Abstract

The invention provides a power distribution network fault detection voltage transformation testing device. The power distribution network fault detection transformation testing device comprises a data monitoring module and a GPRS communication module; the data monitoring module is connected to a monitoring computer through the GPRS communication module; the data monitoring module comprises a voltage transformer, a current transformer, a data collection device and a power supply management module; the data collection device is connected to a primary side of a power distribution transformer through the voltage transformer and the current transformer and is connected to a secondary side of the power distribution transformer through the current transformer and a cable; the power supply management module is connected to the power supply terminals of GPRS communication module and the data collection device; the RS-485 is connected between GPRS communication module and the data collection device; the GPRS module is connected to the Internet and is connected to the monitoring computer through a server of the Internet; the voltage transformer and the current transformer of the data monitoring module are a metering type voltage transformer and a metering type current transformer; an automatic circuit-recloser is connected to a core control unit through a corresponding driving unit; one end of the pulse signal driving module is connected to the core control unit; and a reinforcement rib is arranged on the lower part of an electric member of an upper door.

Description

technical field [0001] The invention belongs to power distribution, in particular to a transformer testing device for fault detection of a distribution network. Background technique [0002] At present, the boxes in which electrical appliances and their circuits are placed are used to distribute power energy. They are centrally installed in the substation of the enterprise to distribute power to the lower-level power distribution equipment in different locations; in daily life, the power distribution cabinets used include cabinets , the incoming line room and power distribution room set side by side in the cabinet, the front door hinged with the incoming line room, the rear door hinged with the power distribution room, the electrical components installed in the incoming line room and power distribution room, opened at the bottom of the cabinet and Through holes for cables entering and exiting the cabinet. [0003] Because the cabinet body of the traditional power distributi...

AI Technical Summary

Problems solved by technology

[0003] Because the cabinet body of the traditional power distribution cabinet is made of metal materials, such as the traditional metal cabinet, and most of the places where the power distribution cabinet is used are outdoors or in the open air, it is often eroded by rain, snow or sand, resulting in a decrease in the strength of the entire cabinet and Cracks appear on the cabinet body, causing the electrical components in the cabinet to come into contact with rainwater, which in turn affects the service life of the electrical components

And when the electrical components are lost, it can only be found during manual regular maintenance. Usually, the period of regular maintenance is long, which will cause the lost electrical components to spontaneously ignite or leak electricity, affecting the power supply of the entire region. It will lead to power outages, and in severe cases, the power distribution cabinet and its connected circuits will spontaneously ignite, threatening the safety of surrounding users
