Description

Technical Field

[0001] The utility model relates to the technical field of withstand voltage testing, in particular to a withstand voltage testing device for insulating paper. Background Technique

[0002] Insulating paper is the general term for electrical insulating paper, which is used as the insulating material for various electrical equipment such as cables and coils, and it needs to have good insulating performance and mechanical strength. The existing withstand voltage test for insulating paper is to apply a specified AC or DC high voltage between the energized part and the non-energized part of the electrical appliance to check the withstand voltage ability test that the insulating paper can bear. During long-term operation, the insulating paper not only has to bear the action of the rated working voltage, but also has to bear the action of overvoltage that is higher than the rated working voltage for a short time during the operation process (the overvoltage value may be several times higher than the rated working voltage value). Under the action of these voltages, the internal structure of the insulating paper will change. When the voltage intensity reaches a certain value, the insulating paper will be broken down, the electrical appliance will not operate normally, and the operator may get an electric shock.

[0003] When the existing withstand voltage tester conducts a withstand voltage test on insulating paper, it is necessary to conduct a withstand voltage test on each point of the insulating paper one by one. However, due to the need for a certain voltage boost time for the withstand voltage test, the cycle required to test a piece of insulating paper is relatively long, and there may be a situation of electric shock when the test personnel connect the insulating paper to the test device. Therefore, the utility model proposes a withstand voltage testing device for insulating paper to solve the above problems. Content of the Utility Model
