III 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 PLC control) system.

IV Construction

Main components of impulse voltage test systems consists two impulse capacitors for each stage, ranging from 800kV to 7200kV cumulative charging voltage.

Test system mainly consists of impulse voltage generator, charging device, damped capacitive divider, automatic control and measure system, chopping sphere gap, and other optional components (supporting resistors, glaninger circuit, etc).

V Principle

The circuit of impulse generator is the Marx multiplier circuit. Impulse capacitors arranged in the stages of the generator are charged in parallel with DC voltage up to 100kV against earth potential and, in order to generate impulses, connected in series by spark gaps. For adjustment of front time and time to half value of the test impulse, the generator stages comprise front wave resistors and tail wave resistors. A short discharge loop guarantees low internal inductances and smooth voltage shape.
