Lightning impulse voltage generator

Descripción del producto

KDLJ-100KV impulse voltage test device is one of the common items of high voltage test of power equipment. JP cabinet and low voltage switch cabinet of power equipment are required to carry out electric shock protection, dielectric property, electrical gap test and impact test to verify or test after design, manufacture and repair. Por lo tanto, the impact voltage test equipment is widely used, and different specifications of impact test equipment can be seen in high-voltage laboratories in factories, research institutions and colleges and universities. KDLJ-100KV impulse voltage test device is made according to the high voltage switch standard requirements: GB7251-10013 “Low-voltage Switchgear and control equipment”, GB3906-10006 “3.6KV-40.5KV AC metal enclosed switchgear and control equipment”, GB/T 11022-10011 “Common technical requirements for High voltage switchgear and control equipment standards”, GB/T 1984-10014 “High voltage AC breaker”, GB/T 7674-10008 “Rated voltage 72.5kV and above gas insulated metal closed switchgear”, etc.. The production of high-voltage impulse generator intelligent control and detection system, which uses programmable controller and computer technology in technology, all control and measurement functions are automatically realized, thus simplifying the system composition, improve the reliability of the system, which enhances the safety of the system in the high-voltage, high-current test, to avoid the equipment may suffer from the harm of high-voltage discharge transient process. The operation interface has the function of man-machine dialogue, the operation process is convenient and simple, and has the characteristics of intelligence.
