Description

TECHNICAL FIELD

[0001] The present application relates to the field of transformer impregnating varnish, in particular to a transformer production impregnating varnish device. BACKGROUND

[0002] The transformer impregnating varnish has four aspects of functions. First, it can enhance the electrical insulation performance of high-frequency transformers. After the high-frequency transformer impregnating varnish process, the electrical strength and insulation resistance of the transformer insulation system can be improved, thereby improving the electrical insulation performance. Second, it can enhance the environmental adaptability of high-frequency transformers. After the high-frequency transformer impregnating varnish process, the moisture resistance, heat resistance, smoke resistance, and resistance to invasion of ultraviolet and other harmful substances can be significantly enhanced, so that the high-frequency transformer can adapt to most harsh environments. Third, it can enhance the mechanical strength of high-frequency transformers. After the high-frequency transformer impregnating varnish process, the mechanical strength of the high-frequency transformer can be effectively enhanced to meet the requirements of shock and impact generated during transportation and use, and also to reduce the noise generated by electromagnetic force during use. Fourth, it can improve the heat conductivity of high-frequency transformers. After the high-frequency transformer impregnating varnish process, the gap between the core and the winding will be filled, which can effectively enhance the overall heat dissipation capacity of the high-frequency transformer, thereby significantly reducing the temperature rise of the high-frequency transformer.

[0003] Through retrieval, a Chinese patent with publication number CN118213187B discloses a transformer production impregnating liquid processing device, which includes an impregnating liquid tank, a discharge tank, and a displacement device. The lower part of the impregnating liquid tank is provided with an impregnating liquid cavity for containing paint liquid, and the upper part of the impregnating liquid tank is provided with a vertical sliding cavity. The discharge tank is sealingly and slidingly installed in the sliding cavity, and one of the vertical sides is provided with a discharge cavity for placing a transformer coil. The displacement device drives the discharge tank to move vertically to drive the transformer coil into the impregnating liquid cavity to complete the impregnating varnish. During the movement of the discharge tank, the bottom and / or top of the discharge tank always maintains sealing with the sliding cavity. The technical advantages of this technology are as follows: by maintaining the sealing state of the sliding cavity during movement, the degree of change in air pressure in the impregnating liquid cavity during each impregnating process can be effectively reduced, thereby reducing the vacuum time during each impregnating process to increase the production efficiency of the transformer coil.

[0004] Through retrieval, the Chinese patent with publication number CN110252580B discloses a vacuum paint dipping device for transformer production and a paint dipping method thereof, which comprises a sealing frame, a paint dipping bin, a front feeding table, a rear feeding table, a vacuum pump and an air exhaust pipe.

The transformer is placed in the paint dipping bin for paint dipping work, which is more convenient. The first motor drives the end seal plate to adjust up and down through the gear belt, which can quickly switch the end seal plate to close or open the paint dipping bin. On the one hand, the device is more convenient for inserting the transformer for paint dipping or passing out the transformer after paint dipping. On the other hand, the rubber strip is connected with the clamping groove below the end of the sealing frame, which greatly improves the sealing performance of the sealing frame to the paint dipping bin.
