摘要
矿用动力中心用多电压干式变压器是近几年适应煤矿需要而发展起来的一种新型产品。简述动力中心用多电压干式变压器的负载试验方法,分析研究了动力中心用多电压干式变压器短路阻抗的计算方法和实例,对矿井的安全生产和节能减排具有技术指导意义。
Multi-voltage dry transformer used in mining power center is a new product developed in recent years to meet the needs of coal mine. Load test method for power center with multi-voltage dry type transformer, the calculation method and example of the short-circuit impedance of the muhi-vohage dry transformer for power center is studied. It has technical guidance to the safety production, energy saving and emission reduction in the coal mine.
