从技术与安全角度来看，在一些故障中，低压配电有一个与高压配电非常为不同的地方，那就是造成低压配电故障的原因很大一部分是人为因素，由于人为操作所引起的设备故障成为主要诱发原因，加大了低压MNS低压抽屉柜故障的发生几率。因此，要正视低压 MNS低压抽屉柜故障的人为故障，从源头上改善这一问题，可以更好地提高设备的使用寿命。

From the perspective of technology and safety, among some faults, low-voltage power distribution is very different from high-voltage power distribution. That is, a large part of the causes of low-voltage power distribution faults are human factors. Equipment faults caused by human operation become the main cause, increasing the probability of low-voltage MNS low-voltage drawer cabinet faults. Therefore, we should face up to the artificial failure of low-voltage MNS low-voltage drawer cabinet failure, and improve this problem from the source, which can better improve the service life of the equipment.

①判断失误造成的开关故障。在低压MNS低压抽屉柜运行过程中，如果由于操作人员经验不足导致的误操作非常为常见。比如，一般负荷开关在失灵的情况下，工作人员如果没有检查开关的额定电流就更换开关，这样就会很容易造成判断开关故障错误，因此在更换了开关之后，很有可能还会引起其他的低压MNS低压抽屉柜的故障。

① Switch failure caused by misjudgment. During the operation of low-voltage MNS low-voltage drawer cabinet, misoperation caused by inexperienced operators is very common. For example, in the case of failure of general load switch, if the staff does not check the rated current of the switch, they will replace the switch, which will easily cause errors in judging the switch failure. Therefore, after the switch is replaced, it is likely to cause failures of other low-voltage MNS low-voltage drawer cabinets.

②低压配电联络开关跳闸。开关跳闸也是一种不容忽视的故障，造成开关跳闸的原因众多，但一般发生这种情况，很多都是由于工作人员没有进行正确的操作，例如是工作人员未对低压进线的电源进行正确操作，从而导致低压配电的联络开关发生跳闸故障。

② Low voltage distribution interconnection switch trips. The switch tripping is also a fault that cannot be ignored. There are many reasons for the switch tripping, but in general, many of these situations occur because the staff did not operate correctly. For example, the staff did not operate correctly on the power supply of the low-voltage incoming line, which led to the tripping fault of the low-voltage distribution interconnection switch.

③负荷开关出现故障。通常所指的负荷开关发生故障，其实就是当电流通过负荷开关时，一旦达到其负荷的非常大值，就会引发负荷开关出现跳闸的现象，然而负荷开关在跳闸后没有及时恢复，就会导致故障的发生。另外如果负荷开关发生故障，就很容易引起操作面板出现问题，那样将会造成低压配电的线路发生大面积停电。

③ The load switch is faulty. The fault of the load switch usually refers to that when the current passes through the load switch, once the load reaches a very large value, the load switch will trip. However, if the load switch is not recovered in time after tripping, the fault will occur. In addition, if the load switch fails, it is easy to cause problems in the operation panel, which will cause a large area power outage in low-voltage distribution lines.

正因为低压MNS低压抽屉柜人为因素出现的故障，很多都是由于工作人员在工作过程中操作方面出现了问题，因为一旦工作人员操作判断失误，这样就很可能出现错误的操作，而错误操作的直接结果就很有可能会造成低压MNS低压抽屉柜的故障。以上就是问题的相关解答了，有需求就来我们网站 //www.aqfitlab.com留言咨询吧！

Many failures of low-voltage MNS low-voltage drawer cabinets caused by human factors are due to problems in the operation of the staff during the working process, because once the staff misjudges the operation, it is very likely that wrong operations will occur, and the direct results of the wrong operations are likely to cause failures of low-voltage MNS low-voltage drawer cabinets.
