Testing of the 1200 kV/120 kJ Impulse Lightning Generator: Key Features, Operating Precautions, and Introduction to Goldhome
The 1200kV/120kJ impulse lightning generator testing equipment is developed and manufactured by Wuhan Goldhome Hipot Electrical Co., Ltd. (Goldhome). As a high-tech enterprise with nearly two decades of experience in the high-voltage testing equipment sector, Goldhome possesses an in-house R&D center and a comprehensive production and testing system. Certified under the ISO 9001 quality management system, the company is dedicated to achieving technological breakthroughs in ultra-high-voltage equipment. This equipment, with its robust performance, is designed for insulation testing of high-end power transmission and transformation equipment. Its core features and operational precautions are as follows.
Core Features: Centered on a rated impulse voltage of 1200 kV and an energy storage capacity of 120 kJ, the unit employs Goldhome's proprietary Marx multi-stage series circuit. Each stage operates at ±200 kV, with a charging stability of ≤±0.8% and a voltage utilization coefficient exceeding 90%. It can precisely replicate standard lightning and operational waveforms, with deviations strictly controlled within ±2%, meeting both international and domestic standards. Featuring an epoxy-insulated modular design, the system has a compact footprint and is suitable for both outdoor and laboratory environments. Equipped with an intelligent programmable control terminal, it offers one-touch start/stop functionality and automatic data logging for convenient operation. Integrated with multiple interlock safety mechanisms to handle complex operating conditions, and built with high-quality components, it boasts a service life exceeding 20 years and low maintenance costs.
Operational Precautions: Operators must be certified and wear insulated protective gear; Before startup, inspect the wiring, grounding, and insulation components to ensure there are no potential hazards. Set parameters precisely before testing; arbitrary changes are strictly prohibited. Stay away from high-voltage areas during operation; touching the equipment or test specimens is strictly prohibited. After testing, disconnect the power supply and wait for complete discharge before disassembly or maintenance. The equipment requires regular calibration and cleaning; store it in a dry, well-ventilated environment. If left idle for extended periods, power it on periodically for maintenance. In case of abnormalities, shut down immediately for troubleshooting; operation with faults is strictly prohibited.
