Abstract

The invention discloses an automatic lightning impulse voltage test system. The system comprises an impulse voltage divider, a chopping device, an impulse voltage generator, a charging power supply, an impulse voltage controller and an impulse measurement and analysis system. The chopping device and the impulse voltage generator are electrically connected to the charging power supply through a control cable, the charging power supply and the impulse voltage controller are connected through an optical fiber, the impulse voltage controller and the impulse measurement and analysis system are connected through an RS232 communication cable, and the impulse measurement and analysis system and the impulse voltage divider are connected through a measuring cable. The impulse voltage controller is used to control charging, triggering and grounding of the impulse voltage generator. The impulse measurement and analysis system is used to obtain an impulse signal generated by a tested product duringa lightning impulse test process, and analyze and process the impulse signal so as to form an analysis report. In the invention, fully-automatic control, measurement and analysis of the lightning impulse voltage test can be realized, and the test efficiency and the accuracy of a test result are increased.

Description

technical field [0001] The invention relates to the technical field of impulse voltage testing, in particular to an automatic lightning impulse voltage testing system. Background technique [0002] In order to assess whether the impact strength of the insulation of power equipment meets the requirements of the national standard and to study and improve the insulation structure of power equipment, an impulse voltage test is required. Impulse voltage test is one of the basic items of high-voltage test for electrical equipment. Impulse tests are required for verification or inspection after electrical equipment is designed, manufactured and repaired. Common electrical equipment, including power transformers, power transformers, high-voltage switches, combined electrical appliances, lightning arresters, power cables and accessories, bushings and insulators, etc., must undergo impact tests, and conduct insulation coordination research, electromagnetic compatibility research and d...
