你好。
Hello.

在这个故事中，我们将学习。
In this story, we will learn.

断路器和按钮。
Circuit breakers and buttons.

首先我们来看看我们的两个断路器，断路器的符号是这样的。
First of all, let's take a look for us two circuit breaker and the symbol of the circuit breaker is like that.

好的？
OK?

这把它扔在这里。
And this throw it in here.

就这样。
And like that.

在这里我们有这样的接触和转身。
And in here we have a touch and turn like that.

然后第二个，我们将看一下紧急按钮。
And then the second one, we will take a look to the emergency button.

好的？
OK?

让我们就在这里。
And let's right here.

紧急按钮和紧急按钮。
Emergency button and for emergency button.

这与断路器类似。
This is similar like circuit breaker.

但我们拥有的，我们有这个，好吗？
But what we have, we have this one, OK?

这里有两个，还有这个。
And that's two here and this one.

第三个，我们有一个停止按钮。
And the third one, we have a stop button.

好吧，没错。
OK, that's right.

这里，停止按钮和停止按钮是常闭的。
Here, a stop button and stop button is normally closed.

像这样，现在聚焦两个符号。
And like that and focus two symbol now.

好的。
OK.

这一个和开始按钮是一样的。
This one and the start button is.

常开。
Normally open.

在这里，让我们放置我们的线。
And in here, let's put our line.

不，这是不正确的。
No, this is not correct.

有点直。
A little bit straight.

好的。
OK.

就这样。
And like that.

在听到我们所听到的内容时，我们听到了这个。
And in hear what we hear, we hear this one.

这是我们的库存启动按钮，现在我们在这里听到的，你可以看到这是打开的触点，好的，所以我可以在这里写，这是常开，这是常闭，紧急按钮也是常闭。
And this is our stock start button and now what we hear in here, you can see this is open contact, OK, so I can write here, this is normal open and this is normally closed and also emergency button is normally closed.

而且，这是我们的断路器。
And also, this is our circuit breaker.

这是常开常闭。
And this is normally open on normally closed.

那么这意味着什么呢？
So what does that means?

在这里，我们将启动电源，OK，功率流将其启动。
In here, we will activate the power, OK, and the power flow will activate it.

我们如何看待断路器？
How can we think the circuit breaker?

想象一下，在您的电气系统中，您有一个线路。
Imagine in your electrical system, you have lined one.

好吧，这是你的脸，你没有好的中性，然后你就在这里了。
OK, this is your face and you have no OK neutral and then you have in here.

这有点遗憾。
This is a little bit sorry.

也许我需要像这样直接扔一点。
Maybe I need to throw it a little bit straight like this.

在这里你可以看到它的断路器，你将把断路器放在这里。
And in here you can see it circuit breaker and you will put circuit breaker to here.

让我们把它变成这样吧。
Let's make it like that.

这是第一件事。
This is the first thing.

好的？
OK?

就这样。
And like that.

然后当你在你的手机中看到这个的时候。
And then when you see this one in your.

这条线路将连接至或加上 - 从断路器然后连接至线路的电气系统。
Electrical systems this line is going to go to or plus -- from the circuit breaker and then to the line.

好吧，不是那样的。
Okay, not like that.

对此表示抱歉并继续。
Sorry for this and continue.

在这里，我将向您展示一个。
In here, I will show you one.

重要的事情，好吧。
Important thing, okay.

这是你的第一行。
This is your line one.

从第一行开始，我们会得到什么？
And from this line one, what will we have?

我们将切断电源。
We will cut our power.

想象一下，这是我们的自然路线，就像从这里开始的那样。
Imagine this is our natural line like that and like that from here.

您可以在电接缝中做什么？
What can you do in the electrical seams?

你往返于城镇之间，想象这里有电源，好吗？
You go to town and from town and imagine in here you have power supply, OK?

一号线和培育从这+ 20 向前。
And Line one and nurture from this plus 20 forward.

从这里开始，零将变为 DC。
And from here, the zero will DC.

当您激活断路器时，断路器会做什么，好吗？
And what circuit breakers do when you activate the circuit breakers, OK?

当您打开电源时，这条线从这里延伸到这里，并且适合我们的设备。
When you turned on, this line goes from here to here and it is fitting to our devices.

这是第一件事。
This is the first thing.

在 TLC 程序内部，我们看一下紧急按钮、停止按钮和启动按钮。
And inside of the TLC programs, if we take a look to the emergency button and stop button and also start button.

然后我们把它放在这里，这也是你在政策计划中的投资组合。
And then let's throw it here, also then this is your portfolio in policy program.

就这样？
And like that?

这是第一次，这是第二次，也是第三次，好吗？
This is the first thing, and this is the second one, and also this is the third time, OK?

您可以听到您所听到的内容。
And you can hear what you hear.

你有一只这样的鹌鹑。
You have a quail like that.

好的，现在这是常闭触点，它使其常闭，这是常闭，这是常开。
OK, now this is normally close contact, it's make it normally closed and this is normally closed and this is normally open.

这是紧急按钮。
So this is for emergency button.

如果紧急按钮没有放置好，常闭对于在电路中使用非常重要。
If emergency button is not placed OK, normally closed is really important to use in your circuits.

如果没有按下紧急按钮，并且如果停止按钮正常但没有按下，则将其放在这里。
And if emergency button is not pressed and also if stop button OK, not press, this is put it to here.

让我们把它变成这样。
Let's make it like this.

如果启动此按钮，请按“确定”，然后这是要点击的 SKU 和名称，例如，电机一号。
And if start this press OK, then this is the SKU and name to hit, for example, motor one.

会发生什么？
What will happen?

紧急停止一是我们的紧急按钮是可以的。
One emergency stop is our emergency button is OK.

有。
There is.

没有人按下停止按钮，好吧。
Somebody is not pressing to stop button, OK.

如果有人按下这个启动按钮，好吧，电机将会转动，因为逻辑是从左到右，好吧，在政策程序或政策中从上到下。
And if somebody pressed to start button this one, OK, what will happen to the motor will turn for the logic is goes from left to right, OK, from up to down in the policy programs or in the policies.

那么，当有人催促开始时，现在会发生什么呢？
So what will happen now while somebody is pressing to start?

好的，当按一下常开听到常开会像这样转回常闭时会发生什么？
OK, what will happen when the press to hear normally open will turn normally closed back like that?

然后，如果有人按下启动按钮，这个常闭触点，当有人按下时，这个触点就会常开。
And then if somebody pressed the start button this normally close contact, this one will be now normally open when somebody pressed.

好的。
OK.

听说是对的，因为。
That's right to hear because of the.

好的。
Good.

好的，现在会发生什么，这个逻辑将被破坏，电机将停止，停止按钮正在工作，或者如果有人按下紧急停止。
OK, so now what will happen, this logic will be broken and that motor will stop, that stop button is working or if somebody pressed emergency stop.

OK，这一切就在急停中完成了。
OK, this will be finished in the emergency stop.

例如，我们也可以把它放在这里，作为防线，我们可以切掉前锋。
We can put it to here also, for example, for the line and we can cut the forward.

好的？
Okay?

该电路中的电压为 24 伏。
We are 24 volt in this circuit.

想象一下这会转到另一个设备的内部或外部设备。
Imagine this goes to another device's internal or external devices.

然后我们可以在这里建造一扇这样的门。
And then in here we can put out a gate like that.

我们可以设置紧急停止或紧急按钮，为什么我们按下紧急按钮并继续前进，好吧，被取消，那一刻发生的事情是，例如，驱动我们的传感器或我们的其他政策。
We can put our emergency stop or emergency button, why we are pressing the emergency button and went forward goes off, OK, becomes cancelled and that moment what happens are, for example, drives our sensors or our other policy.

例如，我们提供的电源几乎总是 24 伏，然后当放置紧急按钮时，电源将被取消。
For example, we are giving a power supply almost always 24 volt, and then this will be cancelled when the emergency button is placed.

那么现在我们需要关注什么。
So now what we need to focus.

我们需要集中注意力。
We need to focus.

紧急按钮是常闭和停止按钮，而启动按钮通常只是在策略逻辑中很重要。
The emergency button is normally closed and stop button, and the start button usually just are important in the policy logic.

这些都是非常重要的事情。
And these are really important things.

好吧，会发生什么？
OK, what happens?

最后总结一下，OK，什么时候断路器比什么时候切换触点？
The last thing the summary, OK, when the circuit breakers than when it switched the contacts?

OK，常开触点变为常闭，常闭触点变为常开。
OK, normally open contacts becomes normally closed and normally close contacts becomes normally open.

例如，这是一次或三次呼叫。
This is, for example, one call or three.

好的。
OK.

并且常开触点变得正常。
And normally open contacts becomes normal.

接近且正常。
Close and normal.

闭合触点变为常开并用于紧急停止。
Close contacts becomes normally open and for the emergency stop.

这通常是关闭的。
This is normally closed.

当您按下时，这些触点将变为常开状态以用于停止按钮。
And when you press, these contacts becomes normally open for the stop button.

自然常闭触点，按下时为常开，启动按钮为自然常开，按下时为常闭。
It is normally close contact natural and when pressed it, it becomes normally open and for the start button, it is naturally normal open and when pressed it, it becomes normally closed.

好啦，就是这个了。
OK, this is the.

宫殿中的断路器和按钮，也在工业自动化或工业中的电气箱中。
Circuit breakers and the buttons in the palaces, also in the in the industrial automation or in the industrial, in the electrical boxes.

这些是非常非常常见的按钮和断路器。
These are really, really common buttons and circuit breakers.
