发布时间:2021-05-31 来源:http://www.tongyuhengcheng.com/ 浏览量:

掌握一些故障的基本处理方法,既可确保用电安全,同时也可为用电单位减少不必要的损失,创造效益。下面就给大家分享几种常见的跳闸故障,希望可以帮到大家。
Mastering some basic fault handling methods can not only ensure the safety of power consumption, but also reduce unnecessary losses and create benefits for power users. Let's share several common tripping faults, hoping to help you.
1轻瓦斯报警
1 light gas alarm
迅速来到该柜前按复位开关,如果报警消除不了,应立即和相关人员去查看该变丈夫器气体继电器轻瓦斯是否动作,如果动作,说明变压器内部有气体产生。
Quickly come to the cabinet and press the reset switch. If the alarm can not be eliminated, you should immediately check with relevant personnel whether the light gas of the gas relay of the transformer acts. If it acts, it indicates that there is gas in the transformer.
原因:一般有三种可能,一是内部有故障,二是缺油,三是加油后没有放净气体。
Cause: generally, there are three possibilities: one is internal failure, the other is lack of oil, and the third is that the gas is not discharged after refueling.
处理方法:把放气阀门打开,待气体放净后,拧紧阀门,回到柜前按复位开关,消除故障信号。
Treatment method: open the vent valve, after the gas is completely discharged, tighten the valve, and press the reset switch before returning to the cabinet to eliminate the fault signal.
2重瓦斯跳闸
2 heavy gas trip
查看是否跳闸,重点查看运行指示灯和综合显示屏。
Check whether it trips or not, and focus on the operation indicator and integrated display.
如果跳闸,说明该柜所带的变压器内部有较大故障,如线圈匝间短路或严重缺油等。
If it trips, it means that there is a big internal fault in the transformer of the cabinet, such as coil turn to turn short circuit or serious oil shortage.
处理方法:应立即通知调度和相关领导,查找真正的原因,待故障处理完毕后通知调度和生产单位,送电试车。
Treatment method: the dispatcher and relevant leaders shall be informed immediately to find out the real cause, and the dispatcher and production unit shall be informed after the fault treatment, and the power supply and test run shall be conducted.
3单相接地跳闸
3 single phase earth trip
通知调度和生产单位,该柜所带的设备有一相接地,找出接地部位,做出有效的处理,报知接地部位,做出有效的处理,报知调度,请示送电试车。
Inform the dispatching and production units that the equipment of the cabinet has one phase grounding, find out the grounding part, make effective treatment, report the grounding part, make effective treatment, report the dispatching, and ask for power transmission and test run.

4电压互感器二次回路断线
4. Secondary circuit disconnection of voltage transformer
一种情况是控制断路器没有在合位,二是控制回路线头松动。
One is that the control circuit breaker is not in the closed position, and the other is that the control circuit head is loose.
处理方法:把开关合上,紧固端子,按复位开关,消除故障信号。5失压(欠压)跳闸
Processing method: close the switch, fasten the terminal, press the reset switch to eliminate the fault signal. 5. Under voltage trip
接到报警,迅速来到柜前查看是否跳闸。
After receiving the alarm, quickly come to the cabinet to check whether it trips.
处理方法:如果跳闸,应立即通知调度,说明网络电压过低,让其与上级电站联系,查找原因,处理故障后请示调度,送电试车。
Treatment method: in case of tripping, the dispatcher shall be informed immediately to explain that the network voltage is too low, and the superior power station shall be contacted to find out the cause. After handling the fault, the dispatcher shall be asked to send power for test run.
6速断跳闸
6 quick break trip
如果监视屏上显示的是速断跳闸。
If the monitoring screen shows quick break trip.
处理方法:应迅速来到该柜前,查看是否跳动闸(看指示灯和断路器的分合指示牌)。
Treatment method: you should quickly come to the cabinet to check whether the switch is jumping (see the indicator light and the opening and closing indicator board of the circuit breaker).
如果跳闸,应迅速报告调度,说明线路或设备有重大故障,然后检查是哪里的线路(可能相间短路或接地)和设备(可能是变压器内部有重大故障)出现了故障,找出并处理完故障后,通知调度,请示送电试车。
In case of tripping, it is necessary to report to the dispatcher immediately to explain that there is a major fault in the line or equipment, and then check where there is a fault in the line (which may be short circuit between phases or grounding) and equipment (which may be a major fault in the transformer). After finding out and handling the fault, the dispatcher shall be informed to ask for power transmission and commissioning.
7过流跳闸
7 over current trip
原因主要有两个,一是线路和设备有故障,二是过负荷。
There are two main reasons, one is the line and equipment failure, the other is overload.
处理方法:如果是首原因,按解决速断跳闸故障的方法处理,如果是另一个原因,应立即通知调度和相关人员。查找过负荷的原因看是否是真的超负荷,还是电机、变压器有故障,待检查处理后,通知调度,请示送电试车。
Treatment method: if it is the first cause, it shall be treated according to the method of solving the quick break trip fault. If it is another cause, it shall immediately notify the dispatcher and relevant personnel. Find out the cause of overload to see if it is really overload, or the motor and transformer are faulty. After checking and handling, inform the dispatcher and ask for power transmission and test run.
以上几种情况,如果没有跳闸,属于信号回路误报,检查信号二次回路,紧固相关二次线,按复位开关,即可消除故障信号。感谢您的阅读,希望以上内容对您有所帮助,如想了解更多精彩内容请点击我们的官网:MNS低压抽屉柜http://www.tongyuhengcheng.com
In the above cases, if there is no trip, it belongs to the signal circuit false alarm. Check the signal secondary circuit, fasten the relevant secondary line, and press the reset switch to eliminate the fault signal.
