Metering device online detection and status evaluation system

Abstract

The invention discloses an online detection and status evaluation system of a metering device, comprising: a gate meter, a gate meter evaluation device, a data concentrator and a master server; The main station server; the gateway meter evaluation device collects the power data of the power gateway node in real time and reads the internally collected power data of the gateway meter, performs data statistics and comparative analysis, and conducts online detection and status evaluation of the gateway meter. Alarm; the master station server performs remote monitoring and status evaluation on the gateway table. The system of the present invention has low cost, convenient installation, simple operation and maintenance, and can detect the voltage, current, power, electricity and other data of the metering device online, and realizes real-time online error detection and alarm for the gateway meter, voltage secondary drop test, The current and voltage secondary load test replaces the existing manual inspection mode.

Description

technical field [0001] The invention relates to a metering device monitoring system, in particular to an online detection and state evaluation system of the metering device. Background technique [0002] The gateway metering device is used for billing or assessment of electric energy metering equipment between countries, between regional power grids, between provincial power grids, between regional power grids, power generation companies connecting to the Internet, and large enterprise users, including gateway power meters, voltage Transformer PT, current transformer CT and secondary circuit, etc. In order to ensure the accuracy of measurement, the above-mentioned equipment needs to be tested and verified regularly. Now the commonly used method is to carry special testing equipment to the site for inspection in a manual cycle. The cycle is long, and it is impossible to grasp the operating status of the equipment in real time, and it is impossible to effectively monitor and ...

In order to ensure the accuracy of measurement, the above-mentioned equipment needs to be tested and verified regularly. Now the commonly used method is to carry special testing equipment to the site for inspection in a manual cycle. The cycle is long, it is impossible to grasp the operating status of the equipment in real time, and it is impossible to effectively monitor and manage many electric energy metering equipment. When the equipment fails, the alarm information is difficult to get timely feedback.
