High-voltage electric energy metering cabinet and method based on real-time monitoring

Abstract

The invention discloses a high-voltage electric energy metering cabinet and a method based on real-time monitoring. A primary device voltage transformer and a current transformer are arranged at a high-voltage switch load side, and power of an electric energy meter and power of an acquisition terminal are provided by a secondary side of the voltage transformer; two voltage transformers are arranged at a high-voltage switch power side; the voltage transformers are connected with a voltage detection circuit; the current transformer is connected with a current detection circuit; a circuit where the high-voltage switch is is connected with a temperature detection circuit; the voltage detection circuit, the current detection circuit and the temperature detection circuit are all connected with a controller; and the controller uploads acquired data to an information acquisition main station. Through monitoring current, voltage and temperature when the high-voltage electric energy metering cabinet works in real time, real-time monitoring on the working state of the intelligent electric meter is realized; and when the intelligent electric meter fails, warning is timely carried out, and corresponding handling and adjustment are carried out.

Description

technical field [0001] The invention relates to the technical field of real-time monitoring, in particular to a high-voltage electric energy metering cabinet and method based on real-time monitoring. Background technique [0002] The high-voltage electric energy metering cabinet includes electric energy meters, collection terminals, voltage transformers, and current transformers. [0003] At present, the voltage and current transformers of the primary equipment in the high-voltage metering cabinet are installed on the load side of the high-voltage switch, and the power supply of the electric energy meter and the collection terminal is supplied by the secondary side of the voltage transformer. [0004] The prepayment function is realized through the collection terminal. After the customer purchases electricity, the collection system will automatically send the purchased electricity to the terminal remotely, and the collection terminal will automatically deduct the electricity...

Problems solved by technology

[0005] In addition, the current high-voltage electric energy metering cabinet does not monitor the temperature, current or voltage in real time during its operation. When the high-voltage electric energy metering cabinet fails, it cannot perform timely fault handling or alarm, which brings great harm to the safe operation of the power grid. security risks
