Electric field measuring device

Abstract

The invention discloses an electric field measuring device. The electric field measuring device comprises a bubble generator, an insulation reservoir, an electrostatic generator, a hydrogen cylinder, a pressure regulating valve, a camera and an image processing computer, wherein the bubble generator is composed of a film forming device, a motor driving the film forming device to rotate and a gas nozzle, and the gas sprayed by the gas nozzle is sprayed to the film forming device to form bubbles; the insulation reservoir provides bubble liquid for the film forming device, and the bubble liquid is insulated from metal pieces in the bubble generator and the ground; the electrostatic generator is connected with the insulation reservoir through a wire, voltage of the bubble liquid in the insulated reservoir produces voltage for the electrostatic generator, and the electrostatic generator has charges; the hydrogen cylinder and pressure regulating valve are connected with the bubble generator through a gas pipe, the flow of hydrogen can be controlled by regulating the pressure regulating valve, the sizes of the bubbles are further controlled, bubble density and air density are equalized, and the bubble gravity is equal to buoyancy; the camera is used for shooting movement of the bubbles in an external electric field; the image processing computer receives videos shot by the camera, processes the videos into movement trails of the bubbles, and calculates the field intensity distribution of the external electric field.

Description

technical field [0001] The invention relates to an electric field measurement device, in particular to a three-dimensional space electric field detection device. Background technique [0002] In order to reduce energy loss in the process of power transmission, UHV DC transmission is adopted. Due to the increase in voltage level of UHV lines, the problem of wire corona is more prominent. If the electric field strength around the wire is too high, it will cause the wire to corona, increase the corona loss of the circuit, and cause environmental problems, including the ground electric field effect, ion flow, radio interference, TV interference, and audible noise. The splitting number and splitting structure of the wire are determined by the line corona characteristic parameters and the mechanical characteristics of the wire. The minimum distance of the line wire to the ground, the width of the line corridor and the crossing distance are mainly determined by the environmental in...
