High-frequency transformer using vacuum impregnation machine dipping process

Insulating varnish is the most important insulating material in electronic transformer products. The quality of insulating varnish is directly related to the quality of electronic transformer products. The damage of electronic transformer products is often caused by the destruction of insulation. Therefore, the improvement and improvement of insulating varnish Level and quality are key to improving the quality and quality of electronic transformer products. So how does the high-frequency transformer use the vacuum impregnation machine dip paint process?

1. There are two aspects to the preparation of Automatic Vacuum Impregnation Machine the process: 壹 is the purification of unimpregnated products, to remove dust and oil; second, to paint, first check whether the quality of the immersion paint is qualified, and then use the special dilution according to the viscosity specified by the immersion paint process. The agent is well prepared.壹 壹 壹 要求 要求 要求 要求 要求 要求 要求 要求 要求 要求 要求 -4 -4 -4 -4 -4 -4 -4 -4 -4 -4 -4 -4 -4 -4 -4 -4 -4 According to different temperatures, most manufacturers have temperature-viscosity curves or data comparison tables for the paints used in the factory for reference.

2, the product pre-baking is to remove the moisture in the core and the coil to facilitate the penetration of the paint. The pre-baking temperature should be between 100 and 130 ° C. The pre-bake time should take into account the heat absorption of the product and the amount of pre-baked product.

3, dipping paint to wait for the temperature of the product to naturally cool to 50-70 ° C is appropriate. The workpiece has a set temperature, which can reduce the viscosity of the paint and facilitate the penetration of the paint. If the temperature of the product is below 45 ° C, the product will absorb moisture. If the temperature of the product is too high, it will affect the stability of the paint. The time of dipping the paint is 10-20 minutes, so that the product does not take bubbles.
