Product Overview
|
The Goldhome HMCJ-1200kV/90kJ impulse voltage generator is a high-voltage testing system designed to generate impulse voltages for evaluating the insulation performance of electrical equipment. The system is intended for lightning impulse full-wave and chopped-wave testing. It can be used in high-voltage test laboratories and electrical equipment testing facilities where impulse voltage tests are required. The system configuration includes an impulse voltage generator, a DC charging unit, a capacitive voltage divider, a chopping device, and a control and measurement system. These components work together to generate the required impulse voltage, measure the test waveform, and support the testing process. For users selecting impulse voltage test equipment, the rated impulse voltage, nominal energy, test object, waveform requirements, and laboratory installation conditions should all be considered. |

Main System Components
1. Impulse Voltage Generator
The impulse voltage generator produces the high-voltage impulse required for insulation testing. Its rated voltage and energy determine the range of test requirements that the system is designed to address.
2. DC Charging Unit
The DC charging unit charges the generator stages before an impulse test. The charging configuration and operating parameters should be matched to the generator design and approved test procedure.
3. Capacitive Voltage Divider
The capacitive voltage divider measures the generated impulse voltage and provides a scaled signal for waveform measurement. The measurement range and performance should be suitable for the intended test voltage and waveform.
4. Chopping Device
The chopping device is used to produce a chopped impulse waveform when required by the test procedure. The technical proposal specifies a DB-1200 multi-sphere chopping device.
5. Control and Measurement System
The control and measurement system supports equipment operation, test control, and waveform observation. The proposed configuration includes a PLC-based control and measurement system and a digital oscilloscope.
Applications
The 1200kV/90kJ impulse voltage generator can be considered for high-voltage impulse testing applications involving electrical insulation.
