Impulse voltage generator (a kind of high voltage generator of impulse wave, used to test the insulation performance of electrical equipment when subject to over voltage (lightning strike) in atmosphere.)

Impulse voltage generator is a kind of high voltage generator of impulse wave, used to test the insulation performance of electrical equipment when subject to over voltage (lightning strike) in atmosphere. The impulse voltage generators produced by the Company can be divided into L type and H type by structure, be divided into indoor fixed type, indoor air cushion type, outdoor fixed type and quick-mounting type by working environment and be divided into swinging arm type and stationary type by discharging manner.

Key words:high voltage generator

high voltage appliance and equipment test

Feature

Beautiful appearance, convenient wave regulation, simple operation, good synchronizing performance, reliable action, being able to meet the testing needs of various high voltage appliance and equipment manufacturer, and being domestically leading and internationally advanced in main performance.

Advanced technology

Applicable for testing pieces of 100kV-7200kV. The resistances at wave head and wave tail can be connected in parallel, and there is discharging clearance between wave tail resistances, used to improve the synchronized discharge performance. The charged parts of the equipment have automatic earthing device. Compact loop structure and low loop inductance.

Application fields

Transformer manufacture, high voltage switch, electrical cable and wire, arrester insulator, electrical testing institute, weather industry, petroleum industry, scientific research and teaching and so on.
