Strong electric field survey meter

Abstract

The invention discloses a strong electric field survey meter, which is capable of surveying strength and direction of an electric field, and belongs to the field of electric field survey. The device comprises a direction surveying part, a strength surveying part and a rotary ring rotating speed surveying part, wherein the direction surveying part consists of metal electrodes, a strong magnet, a small iron ball communicated with an external power supply, a double-sided reflector and a metal rod; when in the electric field, the electrified metal electrodes at two ends freely rotate, and the direction surveying part indicates the direction of the electric field; the strength surveying part comprises a fixed ring and a rotary ring which are made of an insulating material, a rotary metal electrode and a fixed metal electrode which are made of a conductive material and two reflectors; and the rotating speed of the rotary ring is surveyed by a counter after an extraction electrode extracts current. The electric field surveying device is not affected by external conditions, can survey both a uniform electric field and a non-uniform electric field, has wider range of electric field strength surveying, and in particular has higher surveying accuracy when the strength of the electric field is higher. The materials are common, have low cost, and are easy for batch production.

Description

technical field [0001] The invention relates to a strong electric field measuring device, which belongs to the field of electric field measurement. Background technique [0002] The measurement of electric field is of great significance in many places, such as electrospinning, the residence of residents near high-voltage lines, the monitoring of urban environmental pollution, the monitoring of electrostatic fields inside ultra-clean laboratories and factories, and the control of electric fields around high-voltage electrical appliances. [0003] At present, sensors with the principle of charge induction or electromagnetic induction are generally used for electric field measurement in these high-voltage occasions. Because these inductive sensors use the induction principle, the entire sensor needs to be made into a metal structure, so it has a relatively large influence on the distribution of the electric field and power supply problems. Difficult to solve and difficult to co...

Problems solved by technology

[0003] At present, sensors with the principle of charge induction or electromagnetic induction are generally used for electric field measurement in these high-voltage occasions. Because these inductive sensors use the induction principle, the entire sensor needs to be made into a metal structure, so it has a relatively large influence on the distribution of the electric field and power supply problems. Disadvantages such as difficult to solve and difficult to collect signals

In addition, the environment of the general high-voltage electric field is relatively harsh, such as high temperature, strong radiation, etc., where it is inconvenient for people to reach, it is necessary to collect signals from a long distance, which limits the application of this inductive measuring device
