Description

technical field [0001] The present disclosure relates to a steep-front pulse generator, in particular, to a small-scale integrated steep-front pulse generator. Background technique [0002] In the prior art, an impulse voltage generator is generally used to generate a steep leading edge pulse. Specifically, an ordinary open type impulse voltage generator can be used to output an impulse voltage, pass through an overhead bus, and then steepen the impulse voltage through a steepening gap. to obtain the desired steep leading edge pulse. [0003] figure 1 It is a schematic diagram of an existing tower-type impulse voltage generator. [0004] Such as figure 1 As shown, the traditional open-type steep-front pulse generating device is bulky, not easy to transport, and it is not easy to conduct GIS (Gas Insulated Switchgear, gas-insulated combined electrical equipment) insulation characteristic test on site; at the same time, because the device is a traditional The open design, ...

Problems solved by technology

[0004] like figure 1 As shown, the traditional open-type steep-front pulse generating device is bulky, not easy to transport, and it is not easy to carry out GIS (Gas Insulated Switchgear, gas-insulated combined electrical equipment) insulation characteristic test on site; at the same time, because the device is a traditional Open design, due to consideration of insulation requirements, its structural size is large, and it is a nonlinear structure, which makes the loop inductance large, the resulting pulse steepening effect is poor and is greatly affected by environmental factors

When testing a large-capacity sample, it is easy to cause the waveform to fail to meet the standard
