H级干式变压器的特点及运行使用

Features and operation of class H dry-type transformer

我国目前常用的干式配电变压器主要是F级绝缘的环氧树脂浇注型或缠绕型的产品 ,最近 ,国内推出一种采用Nomex绝缘纸作绝缘的H级绝缘干式变压器。通过F1级耐火能力、E2级环境适应能力和承受C2级热冲击能力试验 ,证明它具有良好的电气性能、机械性能和较高的耐热等级 ,并且是一种安全性好的环保产品 ,能在多种恶劣的环境下运行 ,值得推广使用。

The dry type transformer most in use in China is class F insulated encapsulated winding type. Recently,the class H Nomex paper insulated dry type transformer appears on Chinas market,whose outstanding electromechanical performance,heat resistance,safety,environment protecting capability and compatibility are validated through class F1 fire resistant test,class E2 environment compatibility test and class C2 thermal impulse test. As a result,it is worth spreading.
