Abstract

The invention discloses an online sampling inspection device for an electric energy meter and an application method thereof, belonging to the technical field of electric energy metering, comprising: an online sampling inspection device for an electric energy meter, and comparing and comparing the collected pulse frequency with the pulse frequency collected by the online sampling inspection device for the electric energy meter. The tested detection device for remote calibration; also discloses the application method of the online sampling inspection device of the electric energy meter. Through the cooperation of the communication module and the PC electric energy meter verification management system, the remote control of the online sampling inspection device for the electric energy meter can be realized. Calibration, a group The inspectors can inspect the verification devices in multiple locations at one time, and the arrangement of the verification date is controllable, which greatly reduces the possibility of overdue standard calibration of the verification equipment; and the inspectors do not need to travel to and from various units, eliminating the risk of carrying the virus to spread the infection range; At the same time, there is no need to consider portability. An online sampling device for electric energy meters can be installed in each location. The standard equipment can be larger equipment, which can take into account the accuracy of each test meter and leave no calibration blind spots.

Description

Technical field [0001] The present invention belongs to the field of electricity metering, and specific relates to electrical energy meter online sampling devices and its application methods. Background technique [0002] Electricity is one of my country's pillar industry. There are many population bases in my country. The demand for electricity is also large; and with the progress of the development and society, people's ability to use electricity have put forward higher requirements. Electrical energy metering equipment is an indispensable part in the power system. It is directly related to the safety and stability of the power system; so the quality of the electric energy metering has a very important role, so it needs Calibrate the power meter; [0003] At present, my country has undertakes the verification and distribution of energy metering appliances by all provincial marketing service centers. In the face of large-scale demand, the efficient operation of automation verifi...
