在现代科学技术飞速发展的新时期，矿山企业的原始用电设备已远不能满足目前形势发展的需要。对矿山企业而言，所使用的用电设备绝大多数都是基于电磁感应原理工作的，因此，除消耗必要的有功功率外，还必然消耗相当大的无功功率。如变压器、电机的励磁及绕组的漏抗等。矿山企 In the rapid development of modern science and technology in the new era, the original mining equipment business has been far unable to meet the needs of the current situation. For mining enterprises, the vast majority of electrical equipment used are based on the principle of electromagnetic induction work, therefore, in addition to consuming the necessary active power, but also inevitably consume considerable reactive power. Such as transformers, motor excitation and winding leakage reactance. Mining enterprises
