      MNS低壓配電柜的跳閘故障有哪些?

      發布時間:2021-05-31 來源:http://www.8477k.com/ 瀏覽量:

      掌握一些故障的基本處理方法,既可確保用電安全,同時也可為用電單位減少不必要的損失,創造效益。下面就給大家分享幾種常見的跳閘故障,希望可以幫到大家。
      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輕瓦斯報警
      1 light gas alarm
      迅速來到該柜前按復位開關,如果報警消除不了,應立即和相關人員去查看該變丈夫器氣體繼電器輕瓦斯是否動作,如果動作,說明變壓器內部有氣體產生。
      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:一般有三種可能,一是內部有故障,二是缺油,三是加油后沒有放凈氣體。
      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.
      處理方法:把放氣閥門打開,待氣體放凈后,擰緊閥門,回到柜前按復位開關,消除故障信號。
      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重瓦斯跳閘
      2 heavy gas trip
      查看是否跳閘,重點查看運行指示燈和綜合顯示屏。
      Check whether it trips or not, and focus on the operation indicator and integrated display.
      如果跳閘,說明該柜所帶的變壓器內部有較大故障,如線圈匝間短路或嚴重缺油等。
      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.
      處理方法:應立即通知調度和相關領導,查找真正的原因,待故障處理完畢后通知調度和生產單位,送電試車。
      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單相接地跳閘
      3 single phase earth trip
      通知調度和生產單位,該柜所帶的設備有一相接地,找出接地部位,做出有效的處理,報知接地部位,做出有效的處理,報知調度,請示送電試車。
      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電壓互感器二次回路斷線
      4. Secondary circuit disconnection of voltage transformer
      一種情況是控制斷路器沒有在合位,二是控制回路線頭松動。
      One is that the control circuit breaker is not in the closed position, and the other is that the control circuit head is loose.
      處理方法:把開關合上,緊固端子,按復位開關,消除故障信號。5失壓(欠壓)跳閘
      Processing method: close the switch, fasten the terminal, press the reset switch to eliminate the fault signal. 5. Under voltage trip
      接到報警,迅速來到柜前查看是否跳閘。
      After receiving the alarm, quickly come to the cabinet to check whether it trips.
      處理方法:如果跳閘,應立即通知調度,說明網絡電壓過低,讓其與上級電站聯系,查找原因,處理故障后請示調度,送電試車。
      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速斷跳閘
      6 quick break trip
      如果監視屏上顯示的是速斷跳閘。
      If the monitoring screen shows quick break trip.
      處理方法:應迅速來到該柜前,查看是否跳動閘(看指示燈和斷路器的分合指示牌)。
      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).
      如果跳閘,應迅速報告調度,說明線路或設備有重大故障,然后檢查是哪里的線路(可能相間短路或接地)和設備(可能是變壓器內部有重大故障)出現了故障,找出并處理完故障后,通知調度,請示送電試車。
      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過流跳閘
      7 over current trip
      原因主要有兩個,一是線路和設備有故障,二是過負荷。
      There are two main reasons, one is the line and equipment failure, the other is overload.
      處理方法:如果是首原因,按解決速斷跳閘故障的方法處理,如果是另一個原因,應立即通知調度和相關人員。查找過負荷的原因看是否是真的超負荷,還是電機、變壓器有故障,待檢查處理后,通知調度,請示送電試車。
      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.
      以上幾種情況,如果沒有跳閘,屬于信號回路誤報,檢查信號二次回路,緊固相關二次線,按復位開關,即可消除故障信號。感謝您的閱讀,希望以上內容對您有所幫助,如想了解更多精彩內容請點擊我們的官網:MNS低壓抽屜柜http://www.8477k.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.
