2. latching & unlatching circuit basics

你好。
Hello.

在本教程中,我们将学习讲座电路。
In this tutorial, we will learn the lecture circuit.

好,首先,接下来试讲的意义是什么?
OK, first of all, what is the meaning of the lecture in the next trial?

我们知道,当我们按下按钮时,电机就会转动,当我们按下按钮时,呃,当我们松开手时,电机就会停止。
We learn when we press the push button the motor is turning, when we press, uh, and when we released our hand, the motor was stopping.

现在我只想按一次开始按钮,好吗?
And now I just want to press start button once, OK?

然后我想一直转动电机。
And then I want to turn motor always.

我们怎样才能尽职尽责?
How can we duties?

该承包商有一个线圈和常开、常闭触点,然后常开触点就在这里。
This contractor has a coils and normally open, normally close contacts and then normally open contact is here.

确定并左键单击治疗。
OK and left click treat.

想象一下,这是我们的承包商在承包商处于活动状态时常开的触点。
Imagine this is our contractor normally open contacts when the contractor is active.

该打开的触点将常闭,此时该触点将被允许将功率传递到右侧。
This open contact will be normally closed and that moment this contact will be allowed to pass powerful off to the right side.

所以当我把它放在这里时,好吧,当这个接触器活动常闭时会发生什么,然后通过这个常闭接触,电力将从这里开始,将供应给这些承包商以达到、培育。
So when I put it to here, OK, what will happen when this contactors activities will be normally closed, then via this normally close contact, the power will go from here, will ft to supply to these contractor to reach, to nurture.

然后这个承包商就会一直活跃。
And then this contractor will be active always.

因此,让我们测试一次,然后激活模拟器按钮,只需按一次,我们现在就可以看到了。
So let's test once and then activated simulator push button just pressed one times and we are this you can see now.

这通常是通过这些承包商始终激活而关闭的。
This is normally closed via these contractor is activating always.

然后电机转动并按下。
Then the motor is turning and pressing.

但现在你可以看到它了。
But now you can see it.

这是合法的。
This is legit.

那么我们怎样才能打破这个壁架呢?
So how can we broke this ledge?

所以你说,好吧,用一个按钮,我想转动我的电机。
So you said, OK, with the one button, I want to turn my motor.

这正在转变。
This is turning.

这真的很好而且正在发挥作用。
It is really good and it is working.

但突然你意识到有危险。
But suddenly you realize there's a danger.

有一个危险的地方正在发生,你想停止这个马达。
There's a dangerous location is happening and you want to stop this motor.

你怎么能这样做呢?
How can you do this?

想象一下电源离你太远。
Imagine the power supply is too far away from you.

因此,您需要一个停止按钮。
Because of this, you need a stop button.

好的,那么我们就到这里了。
OK, then we are here.

左边的停止按钮,点击它。
Stop button left, click to it.

然后是这个电费单。
And then here, then this power bill.

去。
Go to.

这个承包商。
This contractor.

好的,请稍等。
And OK, just a second.

好的。
OK.

然后,好的,该电源将通过“停止”按钮接触“停止”按钮是常闭按钮,“始终停止”按钮是常闭按钮,通过这些,您可以通过此停止按钮运行电机上的触点,然后有人按下“停止”按钮。
And then, OK, this power will go to contact via Stop Button Stop button is normally closed, always stop buttons are normally closed buttons and via these, you can run the contact on motor via this stop button and then somebody pressed Stop button.

这将断开线路,中断流向培育器的动力,并且该电机动力将被取消。
This will break the line, broke the power flow to the nurture and that this motor power will be cancelled.

好的,我们测试一次。
OK, let's test once.

现在。
Now.

好的。
OK.

所以我按下启动按钮一次,那么现在承包商是合法的。
So I pressed the push button once start button, then now the contractor is legit.

我们现在是常开接触,常闭接触,然后我们就有了。
We are normally open contact now, normally close contact and then we have a.

承包商上的两个电源,然后通过这个接触器清除了九岁的驾车者,我按下了停止按钮。
Power two on the contractor and then via this contactors clears the motorist turning nine, I pressed stop button down.

字样被取消了。
The lettering is cancelled.

传说现在已经被打破,所以没有你所看到的力量。
The legend is broken now, so there is no power than you can see.

它正在开放,强大的法律现在再次被打破,所以你可以看到它是好的、合法的、无承诺的、合法的。
It is opening and the powerful law is broken now again, so you can see it is OK and legit and unpledged and legit.

与字母确认这是字母和确认圆圈的含义不同,这确实是基本的。
And unlike the lettering acknowledging this is the meaning of the lettering and acknowledging circles, this is really basic.

所以你声称电路然后只需一个脉冲,一个按钮,好吧,它开始转动,然后停止按钮并释放那首歌。
So you are alleging the circuit and then with just one pulse, one push button, OK, it's turning and then stop button and unleash that song.

这样我就完成了本教程。
So I'm finished for this tutorial.

在下一个教程中再见?
See you in the next tutorial?
