Description

Technical Field

[0001] This utility model relates to the field of porcelain insulator testing technology, and in particular to a device for testing finished porcelain insulators. Background Technology

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding component, capable of withstanding voltage and mechanical stress. Insulators come in many types and shapes. As a special type of insulating control, insulators play an important role in overhead transmission lines. After production, insulators usually need to have their outer surface inspected before they can be put into use.

[0003] Visual inspection is one of the core standards for insulator inspection. Surface defects can reduce insulation performance, accelerate aging, and even cause problems such as flashover or mechanical fracture. However, the most common visual inspection methods for insulators are observation and testing with common tools, which have low inspection efficiency. Utility Model Content
