Example Embodiment
[0026] The present invention will be further described in detail below in conjunction with the drawings, but the protection scope of the present invention is not limited to this.
[0027] Such as figure 1 As shown, the present invention provides a device for evaluating the arc extinguishing effect of an arc extinguisher. The calibration equipment of this embodiment includes a power module 1 for providing electrical energy to the evaluation device; a voltage waveform acquisition and storage device 2 for acquiring and storing the surge voltage waveform at the contact end of the arc extinguisher 5 to be evaluated; a switch module 3, It is used to provide a sudden current for the inductive load 4, so that the inductive load 4 generates a surge voltage to act on the contact terminal of the switch module 4; the inductive load 4 is used to generate a surge voltage.
[0028] Further, one end of the power supply module 1 is connected to one end of the switch module 3, the other end of the ...
