电气设备跳闸是什么原因呢?

发布时间:2021-03-02 来源:http://www.tongyuhengcheng.com/ 浏览量:

家里安装了几个小型断路器,其中有几个是衔接UPS,服务器设备的,为什么一到晚上12点到2点左右,电流会忽然变的很大,导致衔接服务器设备的几个断路器跳闸,白天不会,并且也不是每天晚上都这样,是为什么呢?电气成套设备厂家给大家做一个分析解答!
There are several miniature circuit breakers installed at home, some of which are connected to ups and server equipment. Why does the current suddenly change a lot from 12:00 to 2:00 in the evening, causing several circuit breakers connected to server equipment to trip, not in the daytime, and not every night? Why? Electrical complete sets of equipment manufacturers to do an analysis!
检查内容有以下几点,正常状况下,假如设计没问题是不会出现以上的那种状况的,出现这种状况的话有线路虚接的可能性大,建议尽量去查查线路。
Check the content of the following points, under normal conditions, if there is no problem with the design, it will not appear the above kind of situation, if there is such a situation, there is a possibility of virtual line connection, it is recommended to check the line as far as possible.
1、去检查配电柜(配电柜、箱式变电站、配电箱)下面的用电设备,检查是否有在事端时间段有大功率输出。
1. Check the electrical equipment under the distribution cabinet (distribution cabinet, box type substation, distribution box), and check whether there is high power output during the incident period.
2、检查配电柜(配电柜、箱式变电站、配电箱)内部及到各用电设备的线路衔接,检查是否有虚接现象。
2. Check the line connection inside the distribution cabinet (distribution cabinet, box type substation, distribution box) and to the electrical equipment, and check whether there is virtual connection.
3、调查在事端期间是否有人为因素(误操作等)引起短路等。
3. Investigate whether human factors (misoperation, etc.) caused short circuit during the incident.
4、检查用电设备(配电柜、箱式变电站、配电箱)是否有损坏(在晚上12点到2点这段时间正是用电低峰,线电压比较高,假如设备本身在损坏边际,如二极管等,在电压到达一定程度的状况下或许出现瞬间击穿现象,然后引起短路)
4. Check whether the electrical equipment (distribution cabinet, box type substation and distribution box) is damaged (during the period from 12:00 to 2:00 p.m., the power consumption peak is low, and the line voltage is relatively high. If the equipment itself is at the edge of damage, such as diode, it may break down instantaneously when the voltage reaches a certain level, and then cause short circuit)

至于配电箱跳闸的原因或许有以下原因:
As for the causes of distribution box tripping, there may be the following reasons:
1、检查空气开关是否损坏。
1. Check the air switch for damage.
2、检查空气开关接线是否正确。不正确并从头接线。
2. Check whether the air switch wiring is correct. Incorrect and rewired from the beginning.
3、检查空气开关负荷侧的线路绝缘,假如短路接地,需求排除故障后才能正常合闸。
3. Check the line insulation at the load side of the air switch. If the short circuit is grounded, the switch can be normally closed only after the fault is eliminated.
电气成套设备公司提示:假如一送电就跳闸,阐明是线路接地短路了。
Electrical equipment company tips: if a power on the trip, clarify that the line is short circuit to ground.
