中间继电器在生活中的具体角色是什么?

来源:http://www.jntongyu.com/ 日期:2021-09-16 发布人:tongjid

从本质上讲,这是一种接力。目前主要用于继电保护和自动控制系统,增加了许多触点,容量和在控制电路中传输中间信号的装置。在安装中,有四种固定,嵌入,轨道和突出的方式。

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.
中间继电器的结构并不复杂,主要由固定铁芯,动铁芯,线圈,弹簧,动触头,静触头,端子和壳体组成。线圈通电后,电磁力将驱动动铁芯拉入,然后驱动从触头,常闭触头分离,常开触头闭合。一旦线圈断电,移动的铁芯将在弹簧的作用下将移动触点带回其原始位置。
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.中间继电器具有一定的负载能力。当负载较小时,可以代替小型接触器,可以控制和节省空间,使电气控制更加精细。
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,继电器的触点容量不大,但不能忽略其负载能力。在控制系统中使用,可以控制其他负载,达到扩大控制能力的目的。
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.
4,一些电气元件经常用于继电器,主要是用其触点的开合来控制。例如,彩色电视中的自动消磁电路,三极管控制中间继电器的开关,已经达到控制消磁线圈开关的作用。
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.考虑到海拔高度,环境湿度和电磁波等干扰因素,关键部件必须完全密封,绝缘性高,电阻强。这种设备具有长期耐受恶劣环境的能力,以及良好的电接触稳定性和开关负载能力而不会过早失效。
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.考虑到振动,冲击,碰撞等因素以及控制系统对地震应力和机械应力的影响,我们建议购买采用平衡电枢机构的小型中间继电器。
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.
本文从概念,结构,功能和采购方法四个方面对中间继电器进行了详细的介绍。我相信每个人在阅读之后都会获得一些东西。
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.
