Transformer is also known as h著還igh-voltage module, s中也tep-up transformer and high-voltage coi舊影l. The main functions of high-voltage 校工coil are voltage conversion, i畫舞mpedance conversion, isolati房少on and voltage stabilizat著少ion, etc., which are widely 畫子used, of various types.

The common materials for hi做坐gh-voltage coil include: enamele亮火d wire, gauze wrapped雪火 wire, silk wrapped wire, and t生房he more commonly used is en術學ameled wire. The requirements for th音子e wire are that the wi時好re can be good, the insulating paint 慢懂layer has sufficient 友化heat resistance and certain corro黃些sion resistance. Insul書黑ation materials shall be used for the來業 insulation between the layers of the c鐘輛oil frame and between th銀可e windings. The moisture-proof metho業弟d adopts the potting method, wh年志ich can enhance the me務為chanical strength of the hig了匠h-voltage coil, improve the i理能nsulation performance 美拍and extend the service life.
