Abstract

The invention discloses thunder and lightning generation device trigger protection equipment, a thunder and lightning generation device and a protection method. In the thunder and lightning generationdevice trigger protection equipment, a trigger pulse generator is configured to generate a trigger pulse voltage. One end of the trigger cable is connected with the trigger pulse generator; the otherend is connected with a plurality of matching resistors; the plurality of matching resistors are respectively connected with the ignition sphere gap of a thunder and lightning generation device body;trigger pulse voltage output by the trigger pulse generator reaches the ignition sphere gap through the trigger cable, the protection sphere gap is connected between the matching resistors and the trigger cable in parallel, one end of the protection sphere gap is grounded, and when counterattack occurs, the protection sphere gap acts to limit voltage at the two ends of the trigger cable and the trigger pulse generator.

Description

technical field [0001] The invention relates to the technical field of high voltage measurement, in particular to a lightning generator trigger protection device, a lightning generator and a protection method. Background technique [0002] Lightning generating devices are widely used in the field of insulation assessment and testing of power equipment. Taking gas-insulated switchgear (GIS) and gas-insulated transmission lines (GIL) in power systems as examples, the lightning impulse test is the key to the assessment of their insulation performance. links. Lightning generating device is the key equipment for lightning impulse test. [0003] When the load capacity of GIS, GIL, transformer, etc. is large and the voltage level is high, the lightning generating device must have a high load capacity and output efficiency. At this time, a compact and large-capacity lightning generating device is required. Under this technical condition, the reliable triggering of the lightning ge...
