Composite insulator pollution risk grade evaluation method and system based on temperature detection

Abstract

The invention discloses a composite insulator pollution risk grade evaluation method based on temperature detection. The method comprises the steps of obtaining temperature rise distribution of a to-be-evaluated composite insulator, relative humidity of an environment where the to-be-evaluated composite insulator is located and an air speed; and inputting the temperature rise distribution of the composite insulator to be evaluated, the relative humidity of the environment and the air speed into the trained neural network to obtain the pollution risk level of the composite insulator. The invention further discloses a corresponding system. According to the method, the neural network is sampled, the pollution risk grade can be obtained only by taking the temperature rise distribution which iseasy to obtain, the relative humidity of the environment and the air speed as input, operation is easy, no specific technical requirement exists for workers, the cost is low, and large-area popularization is facilitated.

Description

technical field [0001] The invention relates to a method and system for evaluating the pollution risk level of composite insulators based on temperature detection, and belongs to the field of finite element calculation of multi-physics fields. Background technique [0002] Silicone rubber composite insulators have been widely used in power systems due to their good anti-pollution flashover performance, light weight, and easy maintenance. Composite insulators have played a vital role in the development of the power industry, but most of them are installed outdoors and are easily affected by severe weather. Factors such as rainwater and atmospheric dust will accumulate a large amount of pollution on the surface of the insulator in a short period of time. After the pollution is damp, the surface conductivity of the composite insulator will decrease, which will greatly reduce the insulation performance of the composite insulator and cause the abnormal temperature rise of the com...
