Embodiment Construction

[0045] see figure 1 , an embodiment of the present invention provides a method for detecting the uniformity of a post insulator composite sheath, the method comprising:

[0046] In step S1, the original infrared thermal image sequence of the composite sheath of the post insulator to be tested is acquired, and the original infrared thermal image sequence includes continuous multi-frame original infrared thermal images.

[0047] Specifically, a thermal excitation source can be used in conjunction with a thermal imager to collect the original infrared thermal image sequence of the composite sheath of the post insulator to be tested.

[0048] The thermal imager is used to detect and identify infrared information, and can convert invisible infrared radiation into measurable signals, so the thermal image sequence of the composite sheath of the post insulator to be tested can be collected. The thermal excitation source is used to actively heat the composite sheath of the post insulato...

Description

technical field [0001] The present application relates to the field of electric power technology, in particular to a method, device and system for detecting the uniformity of a post insulator composite sheath. Background technique [0002] Post insulators belong to high-voltage power station electrical insulators, which are used to support busbars or disconnectors in power stations. The insulator sheath is an insulating part that wraps the mandrel, and is used to protect the mandrel from various factors in the outdoor environment, so that the mandrel maintains high mechanical and electrical properties. The main component of the insulator sheath is silicone rubber. The production process is to use an extrusion device to continuously and evenly wrap the kneaded sheath rubber along the length of the product mandrel with a circular insulating sheath with a thickness of 3-5mm. It is vulcanized under high temperature and pressure. The sheath needs to have a dense and uniform str...
