Description

Technical Field

[0002] During long-term operation, electrical equipment must not only withstand the specified working voltage, but also the overvoltage that exceeds the rated working voltage for a short period of time during operation. Under the influence of these voltages, the internal structure of the electrical insulation material will change. When the overvoltage intensity reaches a certain value, the insulation of the material will break down, the electrical appliance will not be able to operate normally, and the operator may be electrocuted, endangering personal safety.

[0003] An insulation strength testing device is used to test the insulation performance of electrical equipment, cables, insulating materials, etc. Its main function is to test the voltage that the insulating material can withstand in order to determine whether its insulation strength meets the standard requirements. During the test, a high-voltage generator generates a certain voltage and applies it to the object under test. Then, the voltage and current values ​​are measured by a voltmeter and an ammeter. If the object under test can withstand the applied voltage without breakdown or leakage, it is considered that its insulation strength is qualified.

To overcome these disadvantages, this utility model provides an electrical insulation safety performance testing device. Utility Model Content
