because there was a power outage and half the city was out.

因为停电了，全温哥华市都停电了

I finally thought of a solution, though, but...

我终于想到一个解决方案，但是....

2016 was already gone!

2016已经过去了 T^T XD

See, I have this power inverter for use in a car.

看，我有这个车用电源逆变器

You connect it to your cigarette lighter

你把它连接到你的点烟器

or directly to the 12 V battery and it generates AC output.

或直接连接到12 V电池，它就会输出交流电。

So you can use it to power your stuff at home.

所以，你可以用它来替你的东西在家里供电。

You can't drive your car into your home,

你总不能把车子直接开进房子里吧，

but you might have a battery-operated drill

但你可能有一个靠电池操作的钻头

that runs on a 12 V or 14 V battery. Then, you're set!

应该是使用12 V或14 V电池供电,那就开始吧!

Let's connect it up.

将它连接起来

I probably connected it backwards.

我可能弄反了

My luck is sh*t. I never connect it right the first time.

我这真的是狗屎运，每次都能插错电极

F***! Now it doesn't work?!

我艹!这就完了？

Are you kidding me?! Not only it's completely broken,

你在跟我开玩笑吗？！ 不但直接就报废了

its 50A fuse is blown. Who designed this s***?

连50A的保险丝都烧断了.谁设计这狗屁玩儿的？

Reverse-polarity protection reliant on a 50A fuse to blow?!

反极性保护就靠这50A保险丝来断路？

Seriously?! It's like cutting your d*** to prevent pregnancy.

真的吗？ 这就像把你的丁丁切下来防止怀孕。

I replaced the fuse, and now, if I connect my Mooshim multimeter

我换了保险丝,现在如果我连接我的Mooshim万用表

to the input terminals of the inverter in reverse,

到逆变器的输入端，

I can clearly see that there is a diode drop voltage across the terminals.

可以清楚地看到，在端子两端有一个二极管压降。

This is the circuit they have. If you connect the battery here,

这是他们的电路。 如果您在这里连接电池，

the current goes through the fuse here

电流在这里通过保险丝

and powers the circuit here.

并在这里为电路供电。

But if you connect the battery backwards, like this,

但是，如果你连接电池反向，像这样，

then the diode forward-bias and there is a huge current

那么二极管的正向偏置和有巨大的电流

through the fuse that blows the fuse.

将通过保险丝，然后熔断它

And it can't even protect the circuit here!

它甚至不能保护这里的电路！

Even their datasheet says “reverse polarity connection will result

即使他们的数据表说“反极性连接将导致

in a blown fuse and may cause permanent damage to the inverter.”

保险丝断路，可能会对逆变器造成永久性损坏。

Absolute garbage.

绝对烂透了

Well, this is bulls***. Now I have to buy a new inverter.

这真是在放屁.现在我又要买一台新的逆变器。

This wasn't even the focus.

这还不是重点

Okay, let's see. Is there anything on sale?

好吧，让我们来看看。 这有没有大减价的？

Let me test a couple of these and see if it has the same crap circuit.

让我测试一下这些，看看它是否有相同的垃圾电路。

Huh. This has a diode drop, too.

哼.这具有二极管压降了。

Wow, even the Cat has the same crappy protection.

哇，甚至卡特皮勒的逆变器也是同一款垃圾保护。

Seems like the same person designed all of them.

看来是同一个人设计的

Let's just get the cheapest one.

买最便宜的一个就好了

Dear inverter designers, this is the circuit you need.

亲爱的逆变器设计师，这是你需要的电路。

Keep your fuse, change your diode to a TVS diode

保留保险丝，将二极管更换为TVS二极管

and use a MOSFET in this configuration for reverse-polarity protection.

并在此电路中使用MOSFET进行反向极性保护。

Anyway, I have my drill battery

无论如何，我有插座电池

and I've hooked up my Mooshim meter,

我已经扣上我的Mooshim万用表，

so we can measure the current and voltage on my phone.

现在我们可以在手机上看见电流跟电压了。

Now, we connect the battery...

现在，我们连接电池...

and turn on the inverter.

然后开启逆变器。

Here we go. You have around 5 A from the battery at 12 V,

来了. 电池的电压大约为5 A，电压为12 V，

which draws 60W from the battery.

从该电池汲取60W。

This is good, but it drains my puny drill battery quickly.

看上去还过得去，但是这玩儿不用多久就能用干这小电池的电了

So, instead...

所以，我决定...

I can use an LED light.

换成LED灯泡

And you see, it only draws 1 A, or 12 W, from the battery.

你看，它只从电池抽取1A/12 W的电力。

So this is going to last much longer and provides the same brightness.

所以现在就可以撑的更久了，同时提供一样的亮度

Now, I'd like to plug my inverter into the outlet of my house

现在，我想把我的逆变器插入我家的插座

so I can power more things.

然后我就可以用更多的东西了。

And for that I made this harness that you can plug to both sides.

就因为这一点我做了这个工具，该工具可以插向两侧。

First, you plug it to the inverter...

首先，将其插入变压器...

[Pain and profanity]

【疼痛，咒骂】

Any time you connect the power harness, connect it to your load side first,

每次，你想用这插头的话，先插负荷端

so you wouldn't short your power supply or shock yourself.

那样就不会短路或是电到自己了

♪ I'm only human, after all ♪

“Rag'n'Bone Man - Human歌词：我不过只是一个人类”

This is probably the most stupid harness one can make,

这可能是人类有史以来最弱智的双向插头了

because it exposes high voltage on both sides.

因为两边都承受很高的电压

So, don't make it.

所以，不要做。

Let's very carefully plug it in.

小心翼翼的接上去

Yes, we have to make sure our load is not powered from a different source,

是的，我们必须确保我们的负载不是从不同的来源

like the BLEEPING city power!

就像在鸣叫的市电！

The issue is that although both these sources are 120 VAC,

问题是，虽然这两个源是120 VAC，

they are different in many ways.

他们有很多方面的不同。

The yellow sine wave is the city voltage

黄色正弦波是城市电压

and the green wave is the output of the inverter.

而绿波是逆变器的输出.

You can see they don't have the same shape,

你可以看到,它们形状都不一样的

they are not in-phase, or even have the same frequency.

它们不同步，甚至都不是同频的。

So connecting them together shorts their voltages badly.

因此将它们连接在一起会使用会使得电压严重降低

So, in order for me to power a room from a plug,

所以，为了让我从一个插座给一个房间供电，

I have to disconnect the main power and some heavy loads,

我不得不断开主电源和一些负载，

like the washer and the fridge,

像洗衣机和冰箱，

because my inverter cannot take that much power.

因为我的逆变器不能承受这么多的电源。

Actually, that's pretty dumb.

其实，这是非常愚蠢的。

It's better and easier if I just disconnect that specific room,

我把要用的房间的电源断掉了不就行了，

which I believe is breaker #3.

我想应该是三号断路器

Now we can safely plug them in.

现在我们可以安全地插上去了

[Super girlish scream, bleeping]

【娘们的尖叫声，蜂鸣声】

Apparently, it was breaker #2.

显然，这是2号断路器。

Always make sure you open the correct breaker

请确保打开正确的断路器

by connecting the light or something into the plug.

方法是将灯或某物连接到插头中。

But here's a redneck way of knowing which one is the correct breaker.

但这是乡巴佬才会用的方法

Just short the plug in question and the correct breaker opens.

把插头短路不就能打开正确的断路器了

Hahaha! Don't do it!

哈哈哈哈.. 请勿模仿！

One last try.

最后一次尝试。

There! It's working.

看，有了

Two lights, my phone—all working.

两个灯，我的手机——都可以了

One thing you should realize is that your phone line, or internet,

你要知道。电话线或是网线不会

doesn't disconnect when there's a power outage.

在停电时断线的

So this way you can bring them back.

所以这种方式你可以等到来电

[BEEEEEEEP!]

【哔——————】

Oh, now my inverter is complaining.

哦，现在我的逆变器正在抱怨

The problem is that my puny drill battery can't last for long.

问题是，我的小电池不能撑太久

But if you have one of these larger batteries, like this one for example,

但如果你有这些较大的电池，例如

that has 7.2 amp-hours, it can last for much longer.

能供电7.2安培/每小时，它可以撑得更久

Let's turn on the TV by my inverter and measure the current.

让我们通过变压器打开电视，测量一下电流。

It is drawing 16 A from 12 V, so it is around 200 W.

从16A 汲取 12V，因此约为200W。

My battery is 7.2 amp-hours and drawing 16 A from it will shorten its life quicker.

我的电池是7.2安培小时，抽16A的电会让电池更快被抽干

We need a car battery.

我们需要一个汽车电池。

With this, I plug the entire setup into my inverter.

用这个，我把套配置都插进我的逆变器。

The TV, digital box, my phone, the radio and even the light.

电视，数码盒，我的手机，无线电，甚至灯光.

This setup is drawing around 22 A from the battery,

这组设置是从电池汲取约22 A，

and my battery is around 75 amp-hours, which means it'll last for more than 3 hours.

我的电池大约是75安培/每小时，也就是说它能称三小时

So I'm set.

那...好了

Okay, let's return the battery.

好吧，让我们把电池放回去。

Let's try it.

让我们试试看。

[Engine trying to start]

【尝试点火】

[Profanity]

【咒骂】

[Engine still trying to start]

【继续尝试点火】

You know, there are these things called UPS, or uninterruptible power supply,

你知道，有这些东西叫做UPS，或不间断电源，

that output AC, have their own battery and charge it, too.

那玩儿能输出交流电，有它们自己的电池和能充电。

Maybe they are worth the investment.

也许它们是值得砸钱下去的。

You know, this Mooshim meter has become increasingly handy.

你知道，这Mooshim电表已变得越来越方便了。

It would be ashame if I had to give it away.

如果我送人的话我会很惭愧。

Yes, I'm giving away 10 Mooshim meters to my Patreons at Patreon.com.

是的，我会在Patreon.com给我的赞助者们10个Mooshim万用表！

No matter what Mooshim means in German.

不管Mooshim在德语意味着什么。

You can also buy it from these sources.

您还可以从这些渠道购买。

And, you know, I want to make some secret videos that I don't want

而且，你知道不，我想弄一些不太想

everyone to see, available to my Paterons.

给各位看的视频，只提供给我的赞助者们。

Hopefully that's a good idea.

希望这是一个好主意。
