在修理过程中使用诊断技术手段在许多情况下有助于预先发现机车的故障。电力设备的工作是有其代表性的,对电力设备来说,在故障发生之前,缺陷的发展要经历相当长的时间。这就使得想用肉眼及时发现故障非常困难。这里要谈的是最普遍也是最危险的一种缺陷,即各种电气接头接触状态不良。因此,重要的是尽可能早地及时发现缺陷并防止它的不良后果的发生。但是,在实践中却宁可花很多的精力去作事故的原因调查和处 The use of diagnostic techniques in the repair process can, in many cases, help to detect locomotive faults in advance. The work of electrical equipment is representative of the power equipment, the failure occurred before the development of defects to go through quite a long time. This makes it very difficult to find the fault in time with the naked eye. Here to talk about the most common and most dangerous one flaw, that a variety of electrical contact poor state. Therefore, it is important to detect defects as soon as possible and to prevent their adverse consequences. However, in practice, it would rather spend a lot of energy to investigate and investigate the cause of the accident
