继电器的继电特性

继电器的输入信号 x 从零连续增加达到衔铁开始吸合时的动作值 xx，继电器的输出信号立刻从 y=0 跳跃y=ym，即常开触点从断到通。一旦触点闭合，输入量 x 继续增大，输出信号 y 将不再起变化。当输入量 x 从某一大于 xx 值下降到xf，继电器开始释放，常开触点断开。我们把继电器的这种特性叫做继电特性，也叫继电器的输入-输出特性。

1、电磁继电器的工作原理和特性

电磁式继电器一般由铁芯、线圈、衔铁、触点簧片等组成的。只要在线圈两端加上一定的电压，线圈中就会流过一定的电流，从而产生电磁效应，衔铁就会在电磁力吸引的作用下克服返回弹簧的拉力吸向铁芯，从而带动衔铁的动触点与静触点（常开触点）吸合。当线圈断电后，电磁的吸力也随之消失，衔铁就会在弹簧的反作用力返回原来的位置，使动触点与原来的静触点（常闭触点）释放。这样吸合、释放，从而达到了在电路中的导通、切断的目的。对于继电器的“常开、常闭”触点，可以这样来区分：继电器线圈未通电时处于断开状态的静触点，称为“常开触点”；处于接通状态的静触点称为“常闭触点”。

Relay characteristics of relays

The input signal x of the relay continuously increases from zero to the action value xx when the armature begins to draw, and the output signal of the relay immediately jumps from y=0 to y=ym, that is, the normally open contact from off to on. Once the contact is closed, the input x continues to increase, and the output signal y will no longer change. When the input quantity x drops from a value greater than xx to xf, the relay begins to release and the normally open contact is disconnected. We call this characteristic of the relay the relay characteristic, also called the input-output characteristic of the relay.

1. Working principle and characteristics of electromagnetic relay

Electromagnetic relays are generally composed of iron core, coil, armature, contact reed and so on. As long as a certain voltage is added to both ends of the coil, a certain current will flow through the coil, resulting in an electromagnetic effect, and the armature will overcome the pull of the return spring under the action of electromagnetic force attraction to attract the iron core, thereby driving the moving contact of the armature and the static contact (normally open contact). When the coil is powered off, the electromagnetic suction also disappears, and the armature will return to the original position in the spring's reaction force, so that the moving contact and the original static contact (normally closed contact) are released. This suction, release, so as to achieve the purpose of conduction in the circuit, cut off. For the "normally open, normally closed" contact of the relay, it can be distinguished in this way: the static contact in the disconnected state when the relay coil is not powered on is called "normally open contact"; The static contact in the connected state is called "normally closed contact".
