Abstract

The invention discloses an online detecting and state assessing system of a metering device. The online detecting and state assessing system comprises a master meter, a master meter assessing device, a data concentrator and a master station server. The data concentrator obtains internal collected electric quantity data of the master meter in a centralized mode and uploads the internal collected electric quantity data to the master station server; the master meter assessing device collects electric quantity data of a power grid master node in real time, reads the internal collected electric quantity data of the master meter, carries out the data statistics and comparison analysis, conducts online detection and state assessment on the master meter, and gives an alarm for the system abnormal situation; the master station server carries out remote monitoring and state assessing on the master meter. The system is low in cost, convenient to install, easy to operate and maintain, and capable of online detecting the voltage, the current, the power, the electric quantity and other data of the metering device, the real-time online error detecting and alarming, the secondary voltage drop testing, the secondary current and voltage load testing on the master meter are achieved, and an existing manual patrolling mode is replaced.

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 ...
