Problems solved by technology

The AC withstand voltage test is the most direct method to identify the insulation strength of electrical equipment. It is of decisive significance for judging whether the electrical equipment can be put into operation. However, in the AC withstand voltage test, the role of the series resonant voltage stabilizing system is very important. The resonant voltage stabilizing system works in a manual way, which is not precise enough, prone to human error, causing more losses to the test, and greatly affecting the accuracy of the test data. The test data is obtained, which reduces the efficiency of the AC withstand voltage test

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the drawings.

[0015] A series resonance automatic voltage stabilizing system, divided into manual working mode and automatic working mode,

[0016] The working steps of manual working mode are:

[0017] 1) Turn on the power supply of the test product, and check whether the buck-boost action is normal as the power is turned on. If the buck-boost can't work, perform equipment maintenance, and then re-open the test product wiring power supply. If the buck-boost can work, Perform V3 voltage and various overcurrent settings, time and voltage settings;

[0018] 2) With the end of current setting, time and voltage setting, then select manual mode of work and switch cabinet closing, and then perform manual step-up and down-voltage, and then calculate whether it is equal to the test voltage, if it is not equal to the test voltage, switch again Switch on the cabinet and manually boost the voltage. If it is equal...

Abstract

The invention relates to a series-resonance automatic voltage stabilization system working a manual working mode or an automatic working mode. In the manual working mode, the working steps are as follows: a test product is connected and a power supply is turned on; whether a boost or step-down motion is normal is checked with turning on of the power supply; if the boost or step-down motion can not be carried out, equipment maintenance is carried out and then the test product is connected with the power supply and the power supply is turned on; if the boost or step-down motion can be carried out, setting of the V3 voltage and all over currents as well time and voltage setting can be carried out. During the voltage-withstanding test process, a working mode of the series-resonance voltage stabilization system can be selected; and selection of the working way is increased, so that the working efficiency is improved. With working of the automatic working way in the system, the obtaining rate of the testing result can be enhanced, deviation of the artificial test data is reduced, and accuracy of the test data and result is guaranteed.

Description

Technical field [0001] The invention relates to a stabilizing system, in particular to a series resonance automatic voltage stabilizing system. Background technique [0002] The AC withstand voltage test refers to the withstand voltage test in which the specified AC voltage is applied to the test product and maintained for a certain period of time, and the test product does not have flashover and insulation breakdown. The AC withstand voltage test is the most direct method to identify the insulation strength of electrical equipment. It is of decisive significance for judging whether the electrical equipment can be put into operation. However, the role of the series resonance voltage stabilizer system is very important in the AC withstand voltage test. The resonant voltage stabilizing system is operated manually. Such a working method is not accurate enough, and it is prone to artificial deviations, which causes more losses to the test, and makes the accuracy of the test data have...
