從技術與角度來看，在一些故障中，低壓配電有一個與高壓配電非常為不同的地方，那就是造成低壓配電故障的原因很大一部分是人為因素，由于人為操作所引起的設備故障成為主要誘發原因，加大了低壓MNS低壓抽屜柜故障的發生幾率。因此，要正視低壓MNS低壓抽屜柜故障的人為故障，從源頭上改善這一問題，可以更好地提高設備的使用壽命。

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判斷失誤造成的開關故障。在低壓MNS低壓抽屜柜運行過程中，如果由于操作人員經驗不足導致的誤操作非常為常見。比如，一般負荷開關在失靈的情況下，工作人員如果沒有檢查開關的額定電流就更換開關，這樣就會很容易造成判斷開關故障錯誤，因此在更換了開關之后，很有可能還會引起其他的低壓MNS低壓抽屜柜的故障。

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低壓配電聯絡開關跳閘。開關跳閘也是一種不容忽視的故障，造成開關跳閘的原因眾多，但一般發生這種情況，很多都是由于工作人員沒有進行正確的操作，例如是工作人員未對低壓進線的電源進行正確操作，從而導致低壓配電的聯絡開關發生跳閘故障。

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負荷開關出現故障。通常所指的負荷開關發生故障，其實就是當電流通過負荷開關時，一旦達到其負荷的非常大值，就會引發負荷開關出現跳閘的現象，然而負荷開關在跳閘后沒有及時恢復，就會導致故障的發生。另外如果負荷開關發生故障，就很容易引起操作面板出現問題，那樣將會造成低壓配電的線路發生大面積停電。

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.

正因為低壓MNS低壓抽屜柜人為因素出現的故障，很多都是由于工作人員在工作過程中操作方面出現了問題，因為一旦工作人員操作判斷失誤，這樣就很可能出現錯誤的操作，而錯誤操作的直接結果就很有可能會造成低壓MNS低壓抽屜柜的故障。以上就是問題的相關解答了，有需求就來我們網站http://www.143318.com留言咨詢吧！

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.
