Problems solved by technology

[0004] 1) The particle drift method has high measurement accuracy but narrow measurement range, so it cannot be used for strong electric field measurement
[0005] 2) The small ball method has poor stability and low precision due to many factors affected
[0006] 3) The potential balance method is complicated to operate and has poor precision
[0007] 4) Capacitive charging method and charge capture method are not suitable for ultra-high electric field strength (above 10^6kV / m) measurement due to the large-volume metal probe that has a great influence on the original electric field distortion
[0008] 5) The strained optical material method is easily affected by environmental factors such as temperature and humidity

Embodiment Construction

[0078] As shown in the figure, the electric field is indirectly measured by measuring the force (electric field force) of the electric field on the charged body, which is characterized by.

[0079] First, the electric field force acting on the charged body is converted into an angular quantity through elastic thin wires.

[0080] Then, through the optical lever, this angular isolation high-voltage electric field is transmitted to the laser backplane and amplified into displacement.

[0081] Next, the camera 6 converts this amount of displacement into an image digital signal.

[0082] Finally, the parameters of the electric field are obtained through microcomputer image processing, and the measurement is completed.

[0083] The digital measurement system suitable for high-intensity electric field measurement provided by the present invention is characterized in that it is composed of an electric field sensor, a data processing system, a communication system, a positioning syst...

Abstract

The invention discloses an electric field measuring method and a measuring system of the electric field measuring method, and relates to a method suitable for measuring a high-intensity electric field and a digital measuring system of the method, wherein a miniature probe is adopted in the method. The electric field measuring method and the measuring system are suitable for measurement from DC to AC and measurement from a space electric field on the surface of an electric appliance to an environmental space electric field. The measuring system is composed of an electric field sensor, a data processing system, a communication system, a positioning system, a correcting system and a power source. A communication system port is respectively connected with a positioning system port, a correcting system port, a data processing system port and an electric field sensor port; the data processing system obtains digital information from the electric field sensor, the correcting system and the positioning system through the communication system or sends instructions to the electric field sensor, the correcting system and the positioning system; the positioning system obtains position and shape geometrical information of an object to be detected and the electric field sensor by detecting the object to be detected and the electric field sensor in a positioned mode.

Description

technical field [0001] The present invention relates to a method for electric field measurement and its measurement system, in particular to a method with a miniature probe suitable for high-intensity electric field measurement and its digital measurement system, which is suitable for DC to AC, electric field from electrical surface space to environmental space Measurement of the electric field. Background technique [0002] Under the existing technology, there are many environmental space electric field measurement systems, but there is no electric field measurement system that can be used to measure the space electric field on the surface of charged appliances (the electric field sensor probe of the existing electric field measurement system contains many metal parts, which is easy to distort the original electric field , making the measured electric field a distorted electric field of the actual electric field). Therefore, in the prior art, most electrical products are o...
