Description

technical field [0001] The invention relates to the field of equipment detection, in particular to a simulated frequency modulation series resonance test device. Background technique [0002] Before the electrical equipment is officially put into production or operation, it must undergo a large number of tests to ensure its safety and reliability. In various tests, in order to test the reliability of equipment under overvoltage impulse, power frequency voltage, lightning impulse voltage and operation impulse voltage tests are essential. [0003] However, in the power frequency voltage, lightning impulse voltage and operating impulse voltage tests, the test voltage value applied to the test equipment is only to assess whether the equipment can withstand various overvoltages. However, the overvoltage value test experienced by the equipment is different from the effect of the long-term working voltage in the actual operation of the equipment. Whether the equipment that has wit...
