Overview of the HMCJ-600kV/60kJ Lightning Impulse Voltage Generator
The HMCJ-600kV/60kJ Lightning Impulse Voltage Generator is a high-end, specialized high-voltage testing device developed and manufactured by Wuhan Goldhome Hipot Electrical Co., Ltd. (Goldhome). It is primarily used to simulate natural lightning overvoltages and test the insulation withstand capability of medium- and high-voltage power transmission and transformation equipment, serving as a core piece of equipment for power equipment quality control and scientific research testing. As a leading enterprise with nearly two decades of expertise in the high-voltage testing field, Goldhome focuses on the independent R&D of core technologies for impulse testing equipment. The company operates a nationally accredited testing laboratory and a large-scale production base, and has played a leading role in the formulation of numerous industry standards. Through customized technical solutions and a rigorous quality control system, Goldhome has become the preferred supplier of high-voltage testing equipment in the power and new energy sectors.
With "600 kV rated impulse voltage and 60 kJ standard energy storage" as its core parameters, this equipment employs a Marx multi-stage series circuit design to achieve closed-loop operation for energy storage, charging, triggering, and discharge. It can precisely replicate standard lightning full-wave, truncated-wave, and operational impulse waveforms of ±1.2/50 μs, perfectly simulating the instantaneous impact of natural lightning on power equipment. It is used to evaluate the insulation performance of insulators, transformers, and current transformers. With a voltage utilization factor of no less than 0.88 and waveform deviation strictly controlled within ±2%, it fully complies with international and domestic standards such as GB/T 16927 and IEC 60060, ensuring accurate and traceable test data.
Unlike conventional testing equipment, this unit is equipped with Goldhome's proprietary constant-current charging automatic control system, which ensures high charging stability. It can operate continuously and stably without voltage drop or deviation, making it suitable for type testing and quality spot checks of equipment in the 110kV–220kV voltage range. Featuring an epoxy-insulated modular design, the equipment has a compact footprint and allows for flexible installation. Paired with an intelligent programmable control system, it simplifies operational procedures while enhancing operational reliability. Leveraging Goldhome's mature component selection and packaging processes, the equipment boasts a low failure rate, convenient maintenance, and a service life exceeding 20 years. It is widely used in power testing centers, equipment manufacturing plants, and research institutes, providing core testing support for the safe and stable operation of power systems.
