Abstract

The invention provides a simulated frequency modulation series resonance test device, which consist of a computer 14, equipment 25 to be detected, a local discharge detector 22 and a coupling capacitor 24, wherein the computer 14 is used for transmitting control signals to the equipment 25 to be detected and the local discharge detector 22 through a wireless channel, and displaying a voltage digital signal; the equipment 25 to be detected is used for generating a corresponding electrical signal for simulating local discharge; the coupling capacitor 24 is used for applying a coupling discharge signal to a detection impedor 23 to generate a voltage digital signal which corresponds to a discharge signal; the coupling capacitor, the detection impedor, the local discharge detector and the computer are connected in series in sequence. By adopting the simulated frequency modulation series resonance test device provided by the invention, a simulated local discharge test which has the same function as practical equipment can be performed safely and intuitively.

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...
