Embodiment 1

[0016] A microscopic surface analysis system for room temperature vulcanized silicone rubber antifouling flashover paint, including a CCD camera 1, a continuous zoom video lens 2, a bracket 3, a pillar 4, a focusing wheel 5, a fastening wheel 6, a limit ring 7, and a connecting frame 8. Micro surface analysis software9. The observed object is imaged on the photosensitive surface of the sensor in the CCD through the optical system. The image sensor converts the optical signal into an electrical signal (video signal), and the signal displays the image of the object on the software connected to the computer through the Bluetooth system.

[0017] The CCD camera 1 has a magnification of 50 times and uses a photosensitive chip produced by Sony inside. The image of the subject is focused on the CCD chip through the lens, and the CCD accumulates a corresponding proportion of charges according to the intensity of the light. Image signal output. When the image signal is connected to t...

Embodiment 2

[0027] The present invention is a microscopic surface analysis method of room temperature vulcanized silicone rubber antifouling flashover coating, and the specific steps are as follows:

[0028] Step 1. System installation and layout;

[0029] Step 2. Adjust the multiple and focal length of the microscopic observation device; adjust the multiple and focal length of the object to be observed so that the imaging of the object can be maximized.

[0030] Step 3: Capture and upload the image of the microscopic surface of the coating; the image of the subject of the CCD camera 1 is focused on the CCD chip through the lens, and the CCD accumulates a corresponding proportion of charges according to the intensity of the light to form an image signal output. When the image signal is connected to the micro surface analysis software end via Bluetooth, the same image as the original image can be seen.

[0031] Step 4, image processing;

[0032] Step 4.1, image brightness adjustment. Th...

Description

technical field [0001] The invention relates to the field of insulating materials, in particular to a microscopic surface analysis system and method for room temperature vulcanized silicone rubber antifouling flashover coatings. Background technique [0002] As the main component of the power system, power transmission and transformation equipment can be operated safely and stably, which is directly related to the reliability and security of the power grid. Since the power transmission and transformation equipment mainly operates in the outdoor environment, first of all, it is seriously affected by atmospheric conditions and air. Complex external environment and atmospheric conditions such as air pressure, temperature, humidity, icing, pollution, smog, etc. can easily lead to partial discharge of power transmission and transformation equipment, endangering the safe operation of power transmission and transformation equipment; secondly, in addition to the influence of the ext...
