High voltage isolating switch touch finger pressure wireless detection device

Abstract

The present invention provides a wireless detection device for contact finger pressure of a high-voltage isolating switch. The touch finger pressure test module obtains the test data for transmission; the data processing display module is used to receive the test data transmitted by the wireless transmission module, and convert the test data into a touch finger pressure value, and then the touch finger pressure value for processing, calculation and display. The beneficial technical effect of the high-voltage isolating switch contact finger pressure wireless detection device provided by the present invention is that the contact finger pressure of the high-voltage isolating switch is tested online by the contact finger pressure test module to obtain test data, and the test data is transmitted to the Data processing display module.

Description

technical field [0001] The invention relates to the technical field of optoelectronic measurement, in particular to a wireless detection device for contact finger pressure of a high-voltage isolating switch. Background technique [0002] Due to the advantages of foreign isolating switch equipment in terms of quality and operating environment, the maintenance rate of isolating switches is not very high, and the maintenance strategies of foreign developed countries are different from those in China. There are few studies on finger pressure measurement. domestic. [0003] At present, there are three methods for measuring contact finger pressure in China: one is to rely on the experience of the maintenance personnel. The maintenance personnel pull the two arms of the shear force switch with both hands or hold the contact finger to estimate the size of the contact pressure. It is inconvenient and inaccurate; the other is to judge the contact condition of the contact part by test...

Problems solved by technology

[0003] At present, there are three methods for measuring contact finger pressure in China: one is to rely on the experience of the maintenance personnel. The maintenance personnel pull the two arms of the shear force switch with both hands or hold the contact finger to estimate the size of the contact pressure. It is inconvenient and inaccurate; the other is to judge the contact condition of the contact part by testing the contact resistance of the isolating switch circuit, which can only be repaired afterwards and lacks preventive monitoring methods; the other is more advanced is the analog isolation Switching moving contact device, the sensing element is installed on the moving contact of the analog isolating switch, and the moving contact of the analog isolating switch is inserted into the actual closing position of the moving and static contacts of the isolating switch without power on, and then the isolating switch Switch finger pressure for measurement

This measurement method must be measured when the power is off, and it can only be measured once for a short time, and the measurement is not the real contact finger pressure generated when the moving contact is closed, and the contact finger pressure of the isolation switch cannot be implemented. The real-time online monitoring cannot timely reflect the change of contact finger pressure of the isolating switch, and cannot accurately judge the safe closing position when the moving contact is closed.

[0004] In addition, the existing test equipment cannot accurately analyze and process the information collected on site, so it is impossible to formulate an accurate maintenance strategy

[0005] Based on the above description, there is an urgent need for a high-voltage isolating switch contact finger pressure wireless detection device to solve the problems existing in the prior art that cannot accurately analyze and process the information collected on site, and cannot formulate accurate maintenance strategies
