※ purpose
Impulse current generator is mainly used to test the ability of electrical equipment to withstand impulse current stability. It is widely used in impulse current test of zinc oxide arrester valve plate, and meteorological lightning protection can also be used in other research tests.
※ performance
The impulse current generator can produce 4 / 10 μ s、8/20 μ s、10/350 μ s、18/40 μ S standard impulse current waveform. The technical indexes of the waveform comply with the provisions of national standards and IEC standards. The products have passed the ministerial appraisal, and their main technical performance is in the leading position in China, reaching the advanced technology of similar international products.
※ performance
1. Small size, mechanical structure and convenient wave adjustment;
2. High output current (4 / 10) μ S waveform reaches 120ka);
3. The device adopts the push trigger mode of lower ball cylinder, with good synchronization performance and reliable action;
