The complete set of test equipment for KDCJ-1800kV/180kJ impulse voltage generator is suitable for the following specific test scenarios:
1. High voltage insulator impact withstand voltage test
Conduct lightning impulse full wave (1.2/50 μ s) and operational impulse (250/2500 μ s) withstand tests on ceramic insulators, composite insulators, etc. to verify their insulation performance under overvoltage, in compliance with JB/T 7616 and DL/T 557 standards.
2. Impact test for bushings (such as transformer bushings and wall bushings)
Simulate the impact of lightning or overvoltage on the external insulation and internal structure of the casing, and evaluate whether flashover or breakdown will occur.
3. Impulse test of current/voltage transformers
According to the requirements of GB/T 7449, conduct lightning impulse test on the transformer to verify the reliability of its main insulation and inter turn insulation.
4. Type testing of power transformers and reactors
During the research and development or manufacturing stage, conduct lightning impulse tests on large transformers to verify the insulation strength of windings to ground and between phases.
5. Verification of GIS (gas insulated switchgear) and high-voltage switch components
Perform impulse voltage tests on insulation supports, isolation fractures, and other components in GIS to ensure safe operation under extreme overvoltage conditions.
6. Standard tests of scientific research and certification testing institutions
Used for conducting authoritative testing in high-voltage laboratories that comply with national standards such as GB/T 16927 and GB/T 311, supporting product type testing, sampling, or international certification (such as IEC benchmarking).
✅ This equipment is particularly suitable for use in indoor high-voltage testing halls, and can operate continuously to meet the full chain high-voltage testing needs from product development, factory quality inspection to third-party certification.
