750kw的中频炉需要配多大的变压器

额定功率 750 KW 的中频炉，可以选择 额定功率（标称值 800 KVA ）的变压器。

电加热设备的功率因数为 1 ，加上其他附属控制设备，选择 800 KVA 的变压器是合理的。

,正确选择变压器容量是电网降损节能的重要措施之一,在实际应用中,我们可以根据以下的简便方法来选择变压器容量。

我们应该坚持着“小容量，密布点”的原则，配电变压器应尽量位于负荷中心，供电半径不超过0.5千米。配电变压器的负载率在0.5～0.6之间效率最高，而在此时变压器的容量称为经济容量。但是负载如果比较稳定，那么连续生产的情况可按经济容量选择变压器容量。

What size transformer does a 750kw induction melting furnace need to be equipped with?

For an induction melting furnace with a rated power of 750 KW, a transformer with a rated power (nominal value of 800 KVA) can be selected.

The power factor of the electric heating equipment is 1, plus other auxiliary control equipment, it is reasonable to choose an 800 KVA transformer.

The correct choice of transformer capacity is one of the important measures for power grid loss reduction and energy saving. In practical applications, we can choose the transformer capacity according to the following simple methods.

We should adhere to the principle of "small capacity, densely distributed", and the distribution transformer should be located in the load center as far as possible, and the power supply radius should not exceed 0.5 kilometers. The load factor of the distribution transformer has the highest efficiency between 0.5 and 0.6, and the capacity of the transformer at this time is called the economic capacity. However, if the load is relatively stable, the transformer capacity can be selected according to the economic capacity in the case of continuous production.
