Abstract

The invention discloses a complex electrical field measuring system which comprises a complex electrical field sensing and measuring unit, a handset unit and a measured place grounding reference plate-type electrode. According to the system, devices of a complex electrical field can be tested simultaneously at a same measuring position, or a power frequency electric field, a direct-current electric field and an AC / DC combined complex electric field can be respectively measured in a controlled way. Thus, the function of measuring three different electric fields by a same measuring instrument is realized without a computer used as a part for achieving the measuring function, and measured date adopts wireless transmission. the method is direct and can be adopted to conveniently, effectively and accurately measure magnitude of an electric field of an electric transmission line and a convertor station in AC, DC and AC / DC parallel areas at a same measuring point, thus providing scientific data monitoring basis for transmission and transformation project environmental evaluation and research on electromagnetic environment level of AC / DC electric transmission line parallel and cross and span areas. In addition, measurements are convenient and simplified.

Description

technical field

[0001] The invention relates to a mixed electric field measurement system, in particular to a mixed electric field device which can be used to measure AC and DC transmission lines, and belongs to the technical field of power system measurement and detection. Background technique

[0002] With the rapid development of the national grid construction, the transmission lines are getting closer and closer to the areas where residents are active, and the electromagnetic environment problems caused by power frequency electric fields and DC synthetic electric fields have attracted more and more attention. Power frequency electric field is the main electromagnetic environment parameter of AC transmission lines and substations, and DC synthetic electric field is the main electromagnetic environment parameter of DC transmission lines. At the same time, due to the difficulty in selecting transmission line corridors in the economically developed areas of East China, there...
