中频炉专用变压器与普通变压器的区别

中频炉专用的变压器是整流变压器，原因是整流变压器的阻抗相比于普通变压器高，谐波小。变压器 s9 S11主要以民用居多。电压的区别.中频炉用的是工业电，380V普通变压器是民用电，220V 一般来说，这两种变压器原理和结构都没有多大的区别，只是阻抗要求有些不同，另外中频炉变压器高低压线圈间加接地屏蔽。

对于中频炉使用的专用变压器，其在制造用料上，需要进行准确计算参数，选用优质高导磁、低损耗的优质硅钢片制造铁心和导线，还需要以科学方法确定铜铁比例，从制造材料上保证变压器具备较低的空载损耗以及低噪声性能。通过“开源节流”的方法加大变压器的散热量和电流的有效控制，这样就能够确保变压器稳定高效运作。

The difference between special transformer for induction melting furnace and ordinary transformer

The transformer dedicated to the induction melting furnace is a rectifier transformer. The reason is that the impedance of the rectifier transformer is higher than that of ordinary transformers and the harmonics are small. Transformers s9 and S11 are mainly for civilian use. The difference in voltage. The induction melting furnace uses industrial electricity, the 380V ordinary transformer is civil electricity, and 220V. Generally speaking, the principle and structure of the two transformers are not much different, but the impedance requirements are somewhat different. In addition, the induction melting furnace transformer is high. Add grounding shield between low voltage coils.

For the special transformer used in the induction melting furnace, it is necessary to accurately calculate the parameters in the manufacturing materials, select high-quality, high-permeability, low-loss, high-quality silicon steel sheets to manufacture cores and wires, and scientifically determine the copper-to-iron ratio. The manufacturing materials ensure that the transformer has low no-load loss and low noise performance. Through the "open source and throttling" method, the heat dissipation of the transformer and the effective control of the current are increased, so that the stable and efficient operation of the transformer can be ensured.
