Abstract

The invention discloses a movable large current impact generator, which comprises a power supply, an integrated charging device, an impact generator body, a measurement and acquisition unit, a to-be-tested product and a control unit; the impact generator body comprises an H type distributed main capacitors which are not less than 8 grade, the lowest layer of the impact generator body is set as a first grade; the impact generator body comprises eight main capacitors, four discharge sphere gaps, a charging resistor, a head wave resistance and a tail wave resistance. According to the movable large current impact generator, insulation requirement is ensured, meanwhile, device volume and weight are reduced, transportation and movement are convenient, economy and reliability of field tests areimproved; operation is simple, automatic control of charging, discharging, data acquisition and storage is realized through a computer; safety and reliability are achieved, and safety isolation between different electric potentials is carried out through measures such as isolation transformers and optical fiber transmission.

Description

technical field [0001] The invention relates to the technical field of high-voltage testing of power systems, in particular to a mobile high-current impact generator. Background technique [0002] Grounding is an important measure to maintain the safe and reliable operation of the power system and to ensure the safety of electrical equipment and operating personnel, and is an important link in the power system. In some areas, there are a large number of special soil zones such as permafrost and wind-blown sand, and the soil resistivity is high, and it is greatly affected by seasons, climate, and environment. When the grounding devices of substations and transmission lines are in harsh soil conditions, the dispersion effect of the grounding body is greatly affected, resulting in high grounding impedance, which greatly reduces the grounding reliability of the power system and seriously threatens the safe and stable operation of the power grid. On the other hand, with the cont...
