Abstract

The present invention relates to a method and device for testing the tracking resistance performance of an insulating material. The method for testing the tracking resistance performance of an insulating material includes: using an infrared laser with a first preset power to ablate the insulating material to be tested for a first preset time ; Obtain the first ablation amount of the insulating material to be tested; obtain the tracking resistance performance level of the insulating material to be tested according to the first ablation amount and the preset tracking resistance performance level table. Thus, simple and rapid measurement of the tracking resistance performance of the insulating material can be realized.

Description

technical field [0001] The invention relates to the technical field of insulation performance testing, in particular to a method and device for testing the tracking resistance performance of insulating materials. Background technique [0002] Insulation materials used outdoors, such as composite insulators, glass insulators coated with RTV (Room Temperature Vulcanized, room temperature vulcanized) coatings, etc., will accumulate a certain amount of dirt on the surface after long-term operation. Under the action, the leakage current in the dirty area is much larger than that in the clean area, and the dirty area with large leakage current will gradually form a dry area. The appearance of the dry area will lead to serious distortion of the electric field on the surface of the insulating material, and the dry area will bear most of the voltage due to the relatively large equivalent resistance, thereby generating a dry area arc, and the dry area arc will cause the surface of the...
