Problems solved by technology

The advantage of this method is intuitive, but the disadvantage is that the algae on the surface of the insulator has a strong adhesion, and it is difficult to wash the algae on the surface of the silicone rubber with wate

Example Embodiment

[0055] The preferred embodiments of the invention are described in further detail below.

[0056] Such as figure 1 As shown, a method for measuring the degree of algae growth on the surface of silicone rubber based on image processing includes the following steps:

[0057] S1. Measure the average value of the G component corresponding to the photos of the algae at different densities, and establish the functional relationship between the algae density and the average value of the G component. This step can be performed in a laboratory.

[0058] S2. Take a picture of the silicone rubber growing the algae to obtain the average G component of the algae area in the photo, and calculate the density of the algae according to the functional relationship, thereby obtaining the density of the algae on the surface of the on-site silicone rubber insulator.

[0059] In an embodiment, step S1 may include the following steps:

[0060] Such as figure 2 As shown, the upper surface of the silicone r...

Abstract

The invention discloses a measuring method and a measuring apparatus of growth degree of algae on a silicone rubber surface on the basis of image processing. The method includes the following steps: S1) measuring the average value of a G component corresponding to photographs in different algae density, and establishing a function relationship between the algae density and the average value of the G component; and S2) photographing silicone rubber on which the algae grow to obtain the average value of the G component of an algae region in the photographs, and calculating the algae density according to the function relationship. The method avoids a step of taking the algae from a surface of an insulator, thereby avoiding a huge error during the algae taking process. The method only needs photographing during on-site operations, is simple and is free of safety hidden risk, adapts different environments, and satisfies demands on safety and power supply reliability in power generation. Through white balance treatment, difference on color of the photographs due to factors, such as weather, illumination and the like, is reduced as more as possible, thereby avoiding error in the growth degree of algae.

Description

【Technical field】 [0001] The invention relates to high voltage and insulation technology, in particular to a method and device for measuring the growth degree of algae on the surface of silicon rubber based on image processing. 【Background technique】 [0002] Composite insulating materials play a very important role in the field of high voltage external insulation because of their outstanding hydrophobic properties. In high-voltage transmission lines, composite insulators made of composite insulating materials are very common. Its function is to suspend wires to ensure reliable insulation between high-potential wires and ground potential towers; in substations, the surface of post insulators is also widely sprayed with room temperature Vulcanized silicone rubber compound. [0003] The surface of the composite insulating material is a hydrophobic surface, which significantly increases the pollution flashover voltage and improves the reliability of the insulator. However, in...
