從技術(shù)與角度來(lái)看，在一些故障中，低壓配電有一個(gè)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(shè)備故障成為主要誘發(fā)原因，加大了低壓MNS低壓抽屜柜故障的發(fā)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(wèn)題，可以更好地提高設(shè)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(kāi)關(guān)故障。在低壓MNS低壓抽屜柜運(yùn)行過(guò)程中，如果由于操作人員經(jīng)驗(yàn)不足導(dǎo)致的誤操作非常為常見(jiàn)。比如，一般負(fù)荷開(kāi)關(guān)在失靈的情況下，工作人員如果沒(méi)有檢查開(kāi)關(guān)的額定電流就更換開(kāi)關(guān)，這樣就會(huì)很容易造成判斷開(kāi)關(guān)故障錯(cuò)誤，因此在更換了開(kāi)關(guān)之后，很有可能還會(huì)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(lián)絡(luò)開(kāi)關(guān)跳閘。開(kāi)關(guān)跳閘也是一種不容忽視的故障，造成開(kāi)關(guān)跳閘的原因眾多，但一般發(fā)生這種情況，很多都是由于工作人員沒(méi)有進(jìn)行正確的操作，例如是工作人員未對(duì)低壓進(jìn)線的電源進(jìn)行正確操作，從而導(dǎo)致低壓配電的聯(lián)絡(luò)開(kāi)關(guān)發(fā)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(fù)荷開(kāi)關(guān)出現(xiàn)故障。通常所指的負(fù)荷開(kāi)關(guān)發(fā)生故障，其實(shí)就是當(dāng)電流通過(guò)負(fù)荷開(kāi)關(guān)時(shí)，一旦達(dá)到其負(fù)荷的非常大值，就會(huì)引發(fā)負(fù)荷開(kāi)關(guān)出現(xiàn)跳閘的現(xiàn)象，然而負(fù)荷開(kāi)關(guān)在跳閘后沒(méi)有及時(shí)恢復(fù)，就會(huì)導(dǎo)致故障的發(fā)生。另外如果負(fù)荷開(kāi)關(guān)發(fā)生故障，就很容易引起操作面板出現(xiàn)問(wèn)題，那樣將會(huì)造成低壓配電的線路發(fā)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.

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.
