Abstract

The invention provides an electric field detection device which at least comprises a bearing body, a reference electrode layer arranged on the bearing body and at least three induction electrode layers arranged on the bearing body and located above the reference electrode layer. Each induction electrode layer comprises at least four induction electrodes evenly distributed. An independent electric field measurement circuit is formed by each induction electrode and the reference electrode layer. According to the electric field detection device, the induction electrodes distributed on multiple layers are adopted, the induction electrodes and the reference electrodes are all of a strip shape, and the strip-shaped electrodes are small in size, thin, capable of being integrated inside a cap easily and good in concealment performance. Meanwhile, due to the adoption of the induction electrodes distributed on multiple layers, the intensity of an electric field can be detected, the electric field can further be detected at multiple angles in multiple directions, and the direction of the electric field can be judged.

Description

technical field [0001] The invention belongs to the field of electric power and relates to an electric field detection device. 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. It is necessary to detect the electric field to evaluate the impact of power transmission and transformation projects on the electromagnetic environment. [0003] At the same time, in order to ensure the safety of personnel working in a high electric field environment for a long time...
