5. ac vs dc
你好。
Hello.
在本教程中,我们将了解一次交流和直流。
In this tutorial, we will take a look once AC and DC.
那么什么是AC,这又是什么?
So what is AC and what is this?
基本上交流电是交替的。
And basically AC is alternating.
目前,还可以。
Current, OK.
然后这是直流电,然后我们可以从名称来理解。
And then this is direct current and then we can understand from the names.
这是直接的和交替的,它是如何工作的,好吗?
This is direct and alternating and how it is working, OK?
那么你可以想一下,交流电在一个周期内OK,OK,电流向前向后向前向后向前向后。
Then you can think for the alternating current OK in one cycle, OK, the current goes forward and backward and forward and backward and forward and backward.
好的?
OK?
这就是你可以认为交流电,好吧,改变直流电的方向。
This is that you can think alternating, OK, changing the direction for the direct current.
好吧,你有一个直流电从一侧流向另一侧。
You have one direct current flow, OK, from one side to another side.
所以从正极端子到负极端子。
So from positive to negative terminals.
那么工业自动化上,按照你的逻辑,你就会看到这个。
So on the industrial automation, in your logic, you will see this one.
就像这是第一件事,你会看到这个。
Like that this is the first thing and you will see this one.
那么这是什么?
So what is this?
而且,你会看到这将继续这样下去。
And also, you will see this is this will continue like that.
第二个我会在这里画两个。
And the second one and I will draw two here.
第三个是,例如,三个快速电机。
And the third one in the, for example, three fast motors.
好的,我们的电机有三相,它们是 A。
OK, we have three phases to the motor that these are an A.
之间是一个 s。
Between are an s.
我们有 120 度,是 A。
We have 120 degree and it's A.
120度。
120 degrees.
一个。
A.N.
301 为 120 度 60 度。
are 120 degrees for 301 60 degree.
所以这有助于转动电机。
So this is helps to turn motor.
好的,就这样吧。
OK, so one and like that.
好的,就像那样,这样活跃,这些活跃,像那样活跃。
OK, like that and this active and these active and these like active like that.
电机正在向一侧转动。
The motor is turning one side.
或者,例如,如果您更改为快速位置,或者更改了电缆并且电机正在转向另一侧。
Or if you change to fast positions, for example, or an is change to cabling and that the motor is turning another side.
那一刻我们想告诉你什么。
So that moment what we are trying to tell you.
交流电。
Alternating current.
好的。
OK.
正弦方式。
Sinusoidal Way.
好的,所以它是正负的。
OK, so it goes plus and minus.
所以在这里我们有一个 DC 直流电,所以我们打了一个源电池,例如,加和减 OK,或者,例如电源或电池或。
So in here we have a DC direct current, so we hit a source battery like, for example, plus and minus OK, or, for example, power supplies or batteries or.
那么这些都是直接给出一个当前的OK。
Then these are gives a current OK directly.
没有正弦波。
There is no sinusoidal wave.
这是。
This is.
例如,假设这是 12 伏,这将给出 12 12 伏,然后根据您的电路,注册您的电路,您可以看到电流的样子,然后带有交流,嗯,波。
For example, imagine this is 12 volt and that this will give 12 12 volt and then according to your circuit, to register of your circuit, you can see the current look then with the AC, um, waves.
我们所拥有的,然后我们正在生产直流电。
What we have and then we are producing direct current.
然后你也许想知道它是如何工作的或者它是如何发生的。
And then maybe you wonder how it is working or how it is happening.
好的。
OK.
首先,想象这是您的交流信号。
First of all, imagine this is your AC signal.
好的?
OK?
然后你就可以在这里拨打电话了。
And then you have a dialed in here.
然后这里有一个电阻就OK了。
And then in here you have a resistor and OK.
这是工作的最后部分了,我们已经完成了,好吗?
And this is at the end of the working OK, we have at this one, OK?
这就是积极的替代品和消极的替代品的积极。
This one so positive alternatives and negative alternatives at the positive.
好的。
OK.
该二极管将处于活动状态,并且我们在此具有电压电位。
This diode will be active and that we have in here voltage potential.
好的,我们将从这里开始。
OK, that we will get from here.
信号就是这样。
The signal like that.
然后在消极的替代方案中,好的,这种饮食将被激活并且没有输出。
And then in the negative alternatives, OK, this diet will be this activated and there is no output.
然后在一段时间之后呢?
And then after one period?
好的,再来一张。
OK, one more.
呃,还有一个又一个。
Uh, one more and one more.
所以我们从这里得到了一个积极的信号。
So we have a positive this signal from here.
想象一下你正在利用这种突破口,好吧,像这样的饮食突破口?
And imagine you are using the breach, OK, diet breach like that?
好的。
Okay.
我会把它扔到这里。
I will throw it to here.
和。
And.
好的。
OK.
还有凯特,就像那样。
And Kate, like that.
在喧嚣结束时,卡坦宁这里可能有一个执行者,但当积极的替代品,好吧,这种饮食和这种饮食,以及当消极的替代品,好吧,这种饮食和这种饮食时,我们听到什么并不重要。运行一下,就可以进行切入输出了。
At the end of the hullabaloo, Katanning here there may be an executor, but it doesn't matter what we hear when the positive alternatives, OK, this diet and this diet and when the negative alternatives, OK, this diet and this diet will be run, OK will be conducting to cut into output.
在这一期结束时,好吧,加上和减去,我们将拥有这一期。
And at the end of the this one period, OK, plus and minus, we will have this one.
例如,这是一个输出加上五个故障,为电源加盐。
So this is, for example, as an output plus five fault that salt for power supplies.
你有什么,你就有什么。
What you have, you have.
好的,第一行培育并在这里调整电压并作为输出正负,就像电源所做的那样。
OK, line one and nurture and in here adjusting to voltage and as an output plus and minus like what power supplies do.
这是我们的第一个信号。
This is our first signal.
好的,例如 220 伏交流电,输出两个和四个。
OK, 220 volt AC, for example, and output two and four of these.
怎么会出现这样的情况呢?
How it's happening like this?
好的,是用突破饮食还是用饮食和电阻器?
OK, with the breach diets or with the diet and the resistor?
我们收到的信号是盐。
We are getting this signal that salt.
因此,我们将此信号传递给我们的继电器等。
So we are giving this this signal to our, for example, relays, for example.
例如,人们看到接触器线圈占据了我们正在使用的很多区域。
People see, for example, the contactor coils a lot of area we are using.
这是另一个AC OK品牌逆变器或VFD是变频驱动器,好吗?
This is another AC OK for the brand inverter or VFD is variable frequency drives, OK?
例如,到目前为止我们有 L1、L2、L3。
For example, we have L1, L2, L3 so far.
必须有人为你做这件事。
One has to do this for you.
我们将您的锯加倍,这是 280 伏交流电。
We double your saw this is 280 volt AC.
那么此时,您需要了解什么?
So at this point, what you need to understand?
你需要明白这一点,好吗?
You need to understand this one, OK?
所以三四和交流电来回、前进、后退、前进、后退。
So three fours and alternating current goes and back and forward and backward and forward and backward.
这就是 DC 的全部内容。
That's all for the DC.
没有呃。
There is no uh.
方向改变一个方向。
The direction changing one direction.
我们有电流。
We have the current flow.
好吧,这是稳定的,好吧,没有积极或消极的选择。
OK, this is stable, OK, there is no positive or negative alternatives.
就这样。
That's all.
所以最后,你需要知道什么,例如,你也可以使用220伏交流继电器,或者PRC可以工作工作电压220伏公民,一个特殊的单位来看看,两个特点LC,或者您可以用于原位和这是什么。
So at the end of the day, what you need to know, for example, you can use 220 volt AC relays also, or the PRC can work operating voltage 220 volt a citizen, a special unit to take a look, two features of the LC, or you can use for the in situ and for what this is.
但很多时候我们在继电器、脉冲、接触线圈中使用直流电,并且直流电和交流电在电气箱中一起工作。
But a lot of times we are using direct current for the relays, for the pulses, for the contact coils, and DC and AC is working altogether at the electrical box.
它是如何运作的。
How it is working.
也许我想尝试向你解释一下。
Maybe I want to try to explain it to you.
就像这就是你的政策。
Like that this is your policy.
薄层色谱输出。
TLC output.
为什么是三个?
Why three?
好的,这是二和四。
Okay, this is two and four.
好吧,然后这是一和二。
Well, and then this is going to a one and a two.
这是我们的承包商。
This is our contractor.
好的,承包商正在向迫击炮传导 L1、L2、L3。
OK, so the contractor is conducting L1, L2, L3 to the mortar.
因此,对于电机的运行,您需要我们的信号。
So for the run, the motor, you need our signal.
这不是我们的天才、发起人和参展商,例如,这就是我们,罗恩想。
This is not the like, our genius, the promoters and exhibitor, for example, this is us, think Ron.
异步电机,好吧,所以你需要让这个电机运行得非常快,所以 380 或 220 伏交流电。
Asynchronous motor, OK, so you need to run this motor pretty fast, so 380 or 220 volt AC.
但对于接触器,想象一下简单的输出以及您需要提出的内容。
But for the contactor, imagine straightforward for the output of the and for what you need to put forward.
所以你需要这个信号。
So you need this signal.
这就是给你的全部。
That's all for you.
我到这里就结束了。
I'm finished here.
