              中間繼電器在生活中的具體角色是什么?

              來源:http://www.cekidots.com/ 日期:2021-09-16 發布人:tongjid

              從本質上講,這是一種接力。目前主要用于繼電保護和自動控制系統,增加了許多觸點,容量和在控制電路中傳輸中間信號的裝置。在安裝中,有四種固定,嵌入,軌道和突出的方式。

              In essence, this is a relay. At present, it is mainly used in relay protection and automatic control system, adding many contacts, capacity and devices for transmitting intermediate signals in control circuit. In installation, there are four ways of fixing, embedding, track and protruding.
              中間繼電器的結構并不復雜,主要由固定鐵芯,動鐵芯,線圈,彈簧,動觸頭,靜觸頭,端子和殼體組成。線圈通電后,電磁力將驅動動鐵芯拉入,然后驅動從觸頭,常閉觸頭分離,常開觸頭閉合。一旦線圈斷電,移動的鐵芯將在彈簧的作用下將移動觸點帶回其原始位置。
              The structure of the intermediate relay is not complex. It is mainly composed of fixed iron core, moving iron core, coil, spring, moving contact, static contact, terminal and shell. After the coil is energized, the electromagnetic force pulls the driving moving iron core in, and then the driving contact is separated from the normally closed contact, and the normally open contact is closed. Once the coil is de energized, the moving iron core will return the moving contact to its original position under the action of the spring.
              1.中間繼電器具有一定的負載能力。當負載較小時,可以代替小型接觸器,可以控制和節省空間,使電氣控制更加精細。
              1. The intermediate relay has certain load capacity. When the load is small, it can replace the small contactor, control and save space, and make the electrical control more fine.
              3,繼電器的觸點容量不大,但不能忽略其負載能力。在控制系統中使用,可以控制其他負載,達到擴大控制能力的目的。
              3. The contact capacity of the relay is not large, but its load capacity cannot be ignored. When used in the control system, other loads can be controlled to expand the control capacity.
              4,一些電氣元件經常用于繼電器,主要是用其觸點的開合來控制。例如,彩色電視中的自動消磁電路,三極管控制中間繼電器的開關,已經達到控制消磁線圈開關的作用。
              4. Some electrical components are often used in relays, mainly controlled by the opening and closing of their contacts. For example, the automatic degaussing circuit in color TV and the triode controlling the switch of the intermediate relay have achieved the function of controlling the degaussing coil switch.
              1.考慮到海拔高度,環境濕度和電磁波等干擾因素,關鍵部件必須完全密封,絕緣性高,電阻強。這種設備具有長期耐受惡劣環境的能力,以及良好的電接觸穩定性和開關負載能力而不會過早失效。
              1. Considering the interference factors such as altitude, environmental humidity and electromagnetic wave, the key components must be completely sealed, with high insulation and strong resistance. This equipment has the ability to withstand harsh environment for a long time, good electrical contact stability and switching load capacity without premature failure.
              2.考慮到振動,沖擊,碰撞等因素以及控制系統對地震應力和機械應力的影響,我們建議購買采用平衡電樞機構的小型中間繼電器。
              2. Considering vibration, impact, collision and other factors as well as the influence of the control system on seismic stress and mechanical stress, we suggest to buy a small intermediate relay with balanced armature mechanism.
              本文從概念,結構,功能和采購方法四個方面對中間繼電器進行了詳細的介紹。我相信每個人在閱讀之后都會獲得一些東西。
              This paper introduces the intermediate relay in detail from four aspects: concept, structure, function and procurement method. I believe everyone will get something after reading.
