There are many types of contactors, but at present, we still know too little, so we need to know more types. Therefore, Xiaobian takes the opportunity of updating the article on the website to introduce one of the contactors, AC contactors, so that we can understand more types of contactors and expand our knowledge.

交流接觸器運行中的檢查項目有哪些？我們應怎樣來進行它的維護工作呢？下面小編來具體分析講解一下。

What are the inspection items of AC contactor during operation? How should we maintain it? Let's analyze and explain it in detail.

1.運行中的檢查項目

1. Inspection items in operation

(1)其通過的負荷電流，是否在接觸器的額定數值之內。

(1) Whether the load current it passes is within the rated value of the contactor.

(2)接觸器的分合信號指示，是否與電路狀態相符合。

(2) Whether the opening and closing signal indication of the contactor is consistent with the circuit state.

(3)接觸器的運行聲音是否正常，接觸是否良好。

(3) Whether the operation sound of the contactor is normal and whether the contact is good.

(4)電磁線圈有無過熱等現象，電磁鐵的短路環是否有異常等。

(4) Whether the electromagnetic coil is overheated, and whether the short-circuit ring of the electromagnet is abnormal.

(5)滅弧罩有無松動、損傷等，輔助觸點有無燒損現象，以及傳動部分有無損傷等。

(5) Whether the arc extinguishing cover is loose or damaged, whether the auxiliary contact is burned, and whether the transmission part is damaged.

(6)周圍環境中有無不利因素，或者是影響到接觸器正常運行的因素，比如振動、通風不好、灰塵等。

(6) Whether there are adverse factors in the surrounding environment or factors affecting the normal operation of the contactor, such as vibration, poor ventilation, dust, etc.

2.維護

2. Maintenance

(1)接觸器應保持干凈整潔，如有灰塵等應及時進行清除。

(1) The contactor shall be kept clean and tidy, and any dust shall be removed in time.

(2)觸點的磨損情況如何，是否需要進行修復，或者是更換。

(2) What is the wear condition of the contact and whether it needs to be repaired or replaced.

(3)相間絕緣電阻的阻值，應不小于10MΩ。

(3) The resistance value of phase to phase insulation resistance shall not be less than 10m Ω.

(4)觸點動作是否靈活，觸點行程是否符合規定要求。

(4) Whether the contact action is flexible and whether the contact stroke meets the specified requirements.

(5)鐵芯是否緊固，有無松動。

(5) Whether the iron core is fastened and loose.
