  • Hi! I spent the new year's countdown in the dark

    嗨! 我在新的一年的倒计时在黑暗中度过

  • 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 saysreverse 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 phoneall 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!
