【Abstract】 Dual-Pulse high voltage generator consists of 3 parts: high voltage generation, controlling and spark gap switch. It can produce 60 kV high voltage pulse and the width of pulse can be adjusted with changing capacitance of capacitors. 200 pF capacitor and 4000 r/min speed motor are chosen. It produces pulse with 400 ns width, 50 ns front and frequency varying from 0 to 200. Compared with simple pulse generator, the dual pulse generator has advantage of stable output, breakdown-poof for reactor. This device is a fundamental component of equipment for desulfurization and desaltpetre.更多还原
