现阶段,在煤矿的供电系统当中,变压器是较为核心的电器设备,变压器的使用过程当中,由于投用的时间长短差异、所经历的过电压、过电流的损坏程度不同、使用和维护的情况电决不是一样,因此造成变压器出现的故障品种多种多样,要想及时发现故障,分析排除故障,提高检测和诊断故障的能力和准确性,就必须充分运用各种诊断技术对运行中产生的故障进行诊断分析。
At this stage, in the coal mine power supply system, the transformer is the core of the electrical equipment, the transformer during use, due to investment in the length of time difference, the experience of over-voltage, over-current damage to different levels, use and maintenance of the situation Electricity is not the same, resulting in a variety of transformer failure occurred in order to find the fault in time, analyze troubleshooting, improve the ability and accuracy of detection and fault diagnosis, we must make full use of a variety of diagnostic techniques arising from the operation Fault diagnosis and analysis.
