K-8000T Coating thickness analyzer

Quality control in industrial production processes, high-voltage disconnector contact silver plating layer detector, rapid testing of copper silver plating, tin plating thickness, etc., while meeting the elemental analysis of metal composition. The K-8000T coating thickness analyzer is a professional non-destructive testing instrument used for quality control and management in the production process to ensure material quality. The identification of alloy composition in high-tech industries such as shipbuilding and aerospace to ensure product quality and safety; In industries related to the national economy and people's livelihood such as power stations, it is necessary to identify whether the components of equipment meet the standards to ensure the safety of the equipment.

As an important electronic power component in high-voltage distribution equipment, the contacts of disconnectors have a silver-plated layer that is wear-resistant and corrosion-resistant, which can reduce contact resistance. However, if copper contacts without silver plating are used, their resistance will increase significantly after oxidation, which may lead to the possibility of arc erosion of the contacts. The use of copper-silver-plated contacts can significantly reduce the possibility of arc ablation of the contacts. Therefore, in accordance with the requirements of the "Regulations on the Ordering of High-Voltage Disconnectors" issued by State Grid Corporation of China, for the main contacts of high-voltage disconnectors, the thickness of the silver plating layer should be no less than 20um, and for general contacts, the thickness of the silver plating layer should be no less than 8um, with a hardness of no less than 120 Vickers. The silver plating layer on the main contacts of the high-voltage disconnector is also one of the important indicators for equipment acceptance.

High and low voltage distribution cabinets

For electroplating manufacturers, the cost of silver plating in electroplating mainly involves the use of the precious metal silver. Therefore, the thicker the coating, the higher the cost for the electroplating manufacturer. As a result, some unscrupulous electroplating manufacturers use inferior products to pass off as good ones or thin ones as thick ones for silver plating, which seriously affects the acceptance of high-voltage distribution equipment and even leads to some high-voltage distribution equipment manufacturers being repeatedly criticized by the State Grid. If they are repeatedly reported as substandard products, they will be barred from participating in State Grid system bidding for at least half a year to two years, and at worst, they will be directly blacklisted by State Grid Bidding.

At present, the measurement methods for the silver coating thickness of disconnector contacts mainly include on-site testing with a handheld X-ray coating thickness analyzer and testing with an X-ray desktop coating thickness gauge.

The isolation switch contact silver plating layer thickness gauge is an X-ray spectrometer. It can analyze and detect the thickness of the silver plating layer on the switch contact by the X-ray fluorescence obtained after irradiating the silver layer with X-rays. The instrument is divided into handheld and desktop types. Both can quickly and non-destructively measure the thickness of the silver plating layer after irradiating for tens of seconds. Convenience and speed are important instruments for power equipment manufacturers and electroplating and surface treatment enterprises to detect the thickness of product coatings.
