Embodiment Construction

[0033] See figure 1 , This application is a flowchart of a 10kV portable high-voltage broadband electric energy field verification method;

[0034] by figure 1 It can be seen that the embodiment of the present application provides a 10kV portable high-voltage broadband electric energy field verification method, and the method includes:

[0035] S10: Use high-voltage broadband standard meter to perform real-load verification of the high-voltage meter to be verified;

[0036] S20: Use a standard power source to perform dummy load verification on the high-voltage meter to be verified.

[0037] In the embodiment of this application, the on-site verification of the high-voltage meter to be verified mainly includes two aspects: real load verification and dummy load verification. The two verification processes can be considered to exist separately, that is, a single one The verification process can also achieve the purpose of online measurement, and the verification can also be completed by ...

Abstract

The invention discloses a 10kV portable high-voltage broadband power field verification method and device. The method comprises steps: a high-voltage broadband standard meter is adopted to perform real load verification on a to-be-verified high-voltage meter; and a standard power source is adopted to perform virtual load verification on the to-be-verified high-voltage meter. The device comprises the high-voltage broadband standard meter, the standard power source and an error meter. The method has high stability, functions are easy to implement, the applicability is high, and the problems of weak anti-interference ability and low portability in field calibration in the prior art can be solved.

Description

Technical field [0001] This application relates to the technical field of power system electric energy detection, in particular to a 10kV portable high-voltage broadband electric energy field verification method and device. Background technique [0002] With the development of the national economy, the power supply load of the power system is becoming more and more complicated, and the demand for the power supply of the power system is getting higher and higher. Such loads include electric locomotive traction, steel smelting, wind power generation, photovoltaic power generation, car charging stations, etc., and are mostly supporting industries for national development. With the development and utilization of new energy, electric vehicles have also begun to take the stage of history. According to the 2015 national new energy vehicle production and sales situation announced by the China Association of Automobile Manufacturers, a total of 340,400 new energy vehicles were produced in...
