简介交流接触器的运行检查项目与维护

来源:http://www.jntongyu.com/ 日期:2021-08-10 发布人:tongjid

接触器的种类是有很多的,不过目前来看,我们还是了解得太少,因此还需要了解更多种类才行。所以,小编趁网站更新文章这一机会,来介绍接触器中的一种,为交流接触器,以便让大家能够了解接触器更多种类,从而拓展我们的知识面。

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.
交流接触器运行中的检查项目有哪些?我们应怎样来进行它的维护工作呢?下面小编来具体分析讲解一下。
What are the inspection items of AC contactor during operation? How should we maintain it? Let's analyze and explain it in detail.
1.运行中的检查项目
1. Inspection items in operation
(1)其通过的负荷电流,是否在接触器的额定数值之内。
(1) Whether the load current it passes is within the rated value of the contactor.
(2)接触器的分合信号指示,是否与电路状态相符合。
(2) Whether the opening and closing signal indication of the contactor is consistent with the circuit state.

(3)接触器的运行声音是否正常,接触是否良好。
(3) Whether the operation sound of the contactor is normal and whether the contact is good.
(4)电磁线圈有无过热等现象,电磁铁的短路环是否有异常等。
(4) Whether the electromagnetic coil is overheated, and whether the short-circuit ring of the electromagnet is abnormal.
(5)灭弧罩有无松动、损伤等,辅助触点有无烧损现象,以及传动部分有无损伤等。
(5) Whether the arc extinguishing cover is loose or damaged, whether the auxiliary contact is burned, and whether the transmission part is damaged.
(6)周围环境中有无不利因素,或者是影响到接触器正常运行的因素,比如振动、通风不好、灰尘等。
(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.维护
2. Maintenance
(1)接触器应保持干净整洁,如有灰尘等应及时进行清除。
(1) The contactor shall be kept clean and tidy, and any dust shall be removed in time.
(2)触点的磨损情况如何,是否需要进行修复,或者是更换。
(2) What is the wear condition of the contact and whether it needs to be repaired or replaced.
(3)相间绝缘电阻的阻值,应不小于10MΩ。
(3) The resistance value of phase to phase insulation resistance shall not be less than 10m Ω.
(4)触点动作是否灵活,触点行程是否符合规定要求。
(4) Whether the contact action is flexible and whether the contact stroke meets the specified requirements.
(5)铁芯是否紧固,有无松动。
(5) Whether the iron core is fastened and loose.
