A Static Decay Time Tester for Detecting Static Eliminating Devices

Abstract

The invention discloses an electrostatic attenuation time tester for detecting an electrostatic eliminating device. The electrostatic attenuation time tester comprises an electrostatic field tester, a charging electrode plate, a grounding electrode plate, a high voltage generator and a conductive base. The electrostatic attenuation time tester also comprises a charging connecting device which comprises a base and two point contact switches which are installed on the base. The adjacent side of the two point contact switches is provided with a common connecting post, and the other side of the two point contact switches is provided with a positive connecting post and a negative connecting post respectively. The common connecting post and the charging electrode plate, the positive connecting post and the positive discharge electrode of the high voltage generator and the negative connecting post and the negative discharge electrode of the high voltage generator are respectively connected through a lead clamp. The positive discharge electrode or the negative discharge electrode of the high voltage generator is enabled to be contacted with the charging electrode plate through the conductive connecting device so that the charging electrode plate is enabled to be electrified by stable high voltage, and the test accuracy can be enhanced and the labor intensity of test personnel can also be reduced.

Description

technical field [0001] The invention relates to the field of static electricity testing, in particular to a testing instrument for detecting static electricity removing devices. Background technique [0002] Electrostatic field is ubiquitous in people's production and life, and it is a controllable physical field with its unique properties. In recent years, with the rapid development of the economy, people have higher and higher requirements for material life, and various electrical products such as televisions, refrigerators, air conditioners, and computers have become popular in millions of households. However, scientific research has found that various electronic products or electronic equipment will produce a substance that is potentially harmful to the human body during the use of people --- electromagnetic waves, and these electromagnetic waves have a radiation effect on the human body. Common ones, for example, why do people's skin get worse after sitting in front of...

AI Technical Summary

Problems solved by technology

During the test, the tester holds the high-voltage generator in his hand, and makes the positive discharge electrode or the negative discharge electrode of the high-voltage generator contact with the charging plate to charge the charging plate; this kind of operation has the following disadvantages: 1) The operator is grounded through the human body. 2) In the process of the tester holding the high-voltage generator and the charging plate, the difference in contact position, contact force and contact time will affect the charge of the tested sample, and then affect the static electricity. Decay time test accuracy; 3) Hand-held high-voltage generator operation has a certain impact on the health of testers
