對于斷路器、接觸器、繼電器三個機器，很多人實際上并不是很能分開，不過沒關系，今天我們就從三者的“毛病”講起，讓大家對其更多的了解。

　　For circuit breaker, contactor, relay three machines, a lot of people are actually not very can separate, but it doesn't matter, today we will start from the three "fault", let you know more about it.

　　斷路器有什么毛病？

　　觸點過熱，能聞到配電控制柜的味道。經檢查，動觸頭未完全插入靜觸頭，接觸壓力不夠，導致切換能力下降，觸頭過熱。此時應調整操作機構，使動觸頭完全插入靜觸頭。檢修該故障時，一定要注意安全，嚴防電弧對人和設備的危害。對負載和觸點進行檢修后，與負載一起檢查運行情況，直至正常。此故障須注意設備的日常維護，以免造成不必要的傷害。

　　What's wrong with the circuit breaker?

　　Contact's overheated. I can smell the power distribution control cabinet. After inspection, the moving contact is not fully inserted into the static contact, the contact pressure is not enough, resulting in the decrease of switching ability, contact overheating. At this point, the operating mechanism should be adjusted so that the moving contact is fully inserted into the static contact. When repairing the fault, we must pay attention to safety and prevent the harm of electric arc to people and equipment. After inspecting the load and contact, check the operation with the load until normal. This fault must pay attention to the daily maintenance of equipment, so as not to cause unnecessary damage.

　　接觸器有什么毛病？

　　接觸斷相，由于某相的接觸接觸不良或端子上的螺絲松動，使電機無相運行。這時，電機雖然可以轉動，但會發出嗡嗡聲。應立即停止維修。觸點焊接，“停止”按鈕連接，電機不轉，可能有嗡嗡聲。這種故障是由于大的過載電流造成兩相或三相觸點的熔接現象。應立即切斷電源，檢查負載后更換接觸器。如果檢查通電后沒有振動和噪音，說明銜鐵的運動部分被卡住了，只是線圈斷路的故障。

　　What's wrong with the contactor?

　　Contact disconnection, due to the bad contact of a phase or loose screw on the terminal, so that the motor does not run phase. At this time, although the motor can turn, but will emit a buzz. Maintenance should be stopped immediately. Contact welding, "stop" button connection, motor does not turn, there may be a buzzing sound. This failure is due to a large overload current resulting in two - phase or three - phase contact fusion phenomenon. Cut off the power supply immediately, check the load and replace the contactor. If there is no vibration and noise after checking the power, it means that the moving part of the armature is stuck, just the fault of the coil break.

　　繼電器有什么毛病？

　　熱功率當量元件燒毀。如果電機無法啟動或啟動時有嗡嗡聲，則可能是熱繼電器熱敏元件中的保險絲熔斷。出現此類故障的原因是熱繼電器動作過于頻繁，或負側過載。排除故障后，更換相應的熱繼電器，注意重新調整整定值。熱繼電器“誤”動作。這種故障的原因一般有以下幾種：設定值太小，使其動作不過載；工作頻率太高，經常影響熱敏元件。等等。ABB中間繼電器價格也要多關注關注！

　　What's wrong with the relay?

　　Thermal power equivalent element burns out. If the motor fails to start or there is a buzzing sound when it starts, the fuse in the thermal-sensitive element of the thermal relay may blow. The reason for this kind of failure is that the action of thermal relay is too frequent, or the negative side overload. After troubleshooting, replace the corresponding thermal relay and pay attention to readjust the setting value. Thermal relay "wrong" action. The reasons for this kind of failure are generally as follows: The set value is too small to make the action but load; Working frequency is too high, often affecting the thermal element. And so on.
