              ABB接觸器代理的異常及維護咋樣

              來源:http://www.cekidots.com/ 日期:2022-03-25 發布人:tongjid

                ABB接觸器代理的線圈的主要故障是由于通過它的電流過多而過熱而燒壞。電流過大的原因通常是線圈的絕緣損壞,或因機械損壞導致匝間短路或對地短路,或電源電壓過低,動、靜鐵芯接觸不良。關閉,線圈電流過大,線圈過熱燒毀。

                The main fault of the ABB contactor agent's coil is that it overheats and burns out due to excessive current passing through it. The cause of excessive current is usually the insulation damage of the coil, or the short circuit between turns or to the ground caused by mechanical damage, or the voltage of the power supply is too low, and the contact between the moving and static iron core is poor. Shut down. Coil current is too high. Coil overheats and burns.
                由于相觸點接觸不良或連接螺釘松動,電機無相運行。這時,電機雖然可以轉動,但發出“嗡嗡”的聲音。如果發生這種情況,應立即停止維修。
                Due to poor contact or loose connection screw, the motor has no phase operation. At this time, although the motor can turn, but issued a "buzz" sound. If this happens, repair should be stopped immediately.
                按下“停止”按鈕,電機不能停止,有的還會發出“嗡嗡”的聲音。這類故障是由于接觸器工作頻率高、過載使用、負載側短路等,使兩相或三相觸點因過載電流大而熔接。
                Press the "stop" button, the motor can not stop, and some will send out a "buzzing" sound. This kind of fault is due to the contactor working frequency is high, overload use, load side short circuit, so that the two phase or three phase contact due to overload current and fusion.
                ABB接觸器代理正反向聯鎖失效,或兩個接觸器因誤動作同時投入工作,造成相間短路;或者由于接觸器動作過快,在轉換過程中發生電弧短路。
                ABB contactor agent positive and negative interlock failure, or two contactors due to misaction at the same time into work, resulting in phase short circuit; Or because the contactor action is too fast, in the process of conversion arc short circuit.
                定期檢查ABB接觸器代理各部分的工作情況;接觸器活動部分不卡死,動作靈活,實體部分不松動;觸點和鐵芯表面部分應保持清潔,如有油脂應及時清洗。當觸點磨損嚴重時,應及時更換。
                Check the working condition of each part of ABB contactor agent regularly; The active part of the contactor is not stuck, the action is flexible, and the entity part is not loose; Contact and core surface should be kept clean, if there is grease should be cleaned in time. When the contact wear is serious, it should be replaced in time.
