Product Desciption

impluse voltage test system
I.Profile
Impulse current generator is mainly used to test stability of electrical equipment to withstand impulse current. It is widely used in impulse current test of Zinc Oxide arrester valve, and weather protection can also be applied to other research experiments.
The impulse current generator can generate 4/10us, 8 / 20us, 10 / 350us, 18 / 40us current waveform, provides the technical indicators in line with national standards and IEC standards, the product passed the main technical performance in the domestic leading position, reached the international advanced technology of similar products.
II.Advantage
1. Small demension, compact structure and convenient wave adjustment.
2. Strong output current (4/10us waveform reache up to 120kA).
3.Ball air cylinder to push trigger mode, which has good synchronous performance and reliable action.
4. Each main capacitor bushing has a large energy free energy absorption resistance on the sleeve to ensure the safety of the main capacitor.
5. Integrated system of constant current charging computer measurement and control is adopted, with high degree of automation and strong anti-interference ability.
