Product introduction

NACJ 4800 Automatic Lightning Impulse Voltage Generator，is mainly used in electric power e such as power transformers, transformers, combined electrical composite insulators, surge arrester and other tested objects to carry out the impulse voltage test for full wave lightning impulse voltage, chopped wave lightning impulse voltage, operating shock wave and steep wave, testing insulation performance.

1200kV / 2400kV and 4800kV series impulse voltage generator can produce three kinds of impulse voltage waveform: standard lightning full-wave, operating wave and lighting chopped wave. 1200kV series impulse voltage generator can produce eight kinds of impulse voltage waveform: standard lighting wave, operating wave, lighting chopped wave, oscillating lighting wave, oscillating operating wave, steep wave of line insulator, steep wave of composite insulators and transformer inductive operation wave. The technical indicators is in line with national standards and IEC standards, has passed the ministerial appraisal, the main technical performance is in the domestic leading position, has reached the advanced level of international similar products.

The Characteristics of the products

(1) Complete configuration with wide voltage levels in the whole set of device.

(2) Small circuit inductance of the impulse voltage generator, a band-stop filtering measures is adopted so that a standard impulse wave is still generated even under a large capacity load and large load capacity, it is applied to scientific research and business units.

(3) Large voltage utilization factor, lightning wave and operating wave are not less than 90% and 80%;

(4) Compact structure, beautiful appearance, convenient modulated wave, simple operation, good synchronizing performance and reliable operation;

(5) Adopting SCR or LC constant-current charging automatic control technology, which is high automation and strong anti-interference ability.

(6) Chopped wave delay is adopt the delay mode of electronic delay adjustable circuit L-C.

(7) Computer controlled to measure (fiber) system.
