An on-site operation detection system for metering equipment

Abstract

The invention discloses a detection system for the field operation of metering equipment, and the system comprises a power distribution cabinet, a mutual inductor detection system, a disconnecting switch, an I-shaped special transformer collection terminal, a digitalized energy meter, and a special transformer collection terminal meter box, wherein the power distribution cabinet, the mutual inductor detection system, the disconnecting switch, the I-shaped special transformer collection terminal, the digitalized energy meter and the special transformer collection terminal meter box are connected sequentially. The special transformer collection terminal meter box is connected with at least one low-voltage metering box through a line. The low-voltage metering box is connected with a load, and the line is connected with an I-shaped concentrator and a mutual inductor type three-phase intelligent electric meter branch unit. The interior of the special transformer collection terminal meter box is mainly provided with a III-type special transformer collection terminal and a three-phase intelligent electric energy meter main unit. The system can achieve the field operation detection of metering indexes, analyzes the variation tendency of the error data of metering equipment with a single variable, and can be used for the research of the failure mechanism of the metering equipment and forming a stability evaluation system of the metering equipment.

Description

technical field [0001] The invention relates to the technical field of electric power detection, in particular to an on-site operation detection system for metering equipment. Background technique [0002] The electric energy metering device is the only tool for measuring electric energy, and it is the main basis for the three parties of power generation, supply and consumption to settle electricity trade. The accuracy of the electric energy metering device is directly related to the three parties Therefore, it is necessary to study the failure mechanism of metering equipment to improve the operation stability and measurement reliability of metering equipment. How the on-site operation of the electric energy metering device will affect the occurrence of metering errors and metering equipment failures is a very important part of the study of the failure mechanism of metering equipment. [0003] However, the current research on the measurement error of measurement equipment i...

Problems solved by technology

[0003] However, the current research on the measurement error of measurement equipment is mainly carried out in the laboratory, which cannot fully simulate the actual operation of the measurement equipment on site. In the prior art, there is little reference to a detection system for detecting the measurement equipment in different environments. On-site operation conditions to study the relationship between the measurement errors and failures of metering equipment such as smart energy meters, power consumption information collection equipment, low-voltage metering boxes, and transformers, and the on-site operating environment
