中文

我有两个问题,希望有人比我更有经验。

背景:我正在进行车库中的粘土,需要建立一个需要(a。)瓦特的照明系统,并且(b。)恒定电压,所以照明保持极其一致[不会变暗或闪烁尽管其他人使用outlets]。

车库在公寓大楼内连接到约20个其他车库,因此它不是典型的房子持有车库。

问题1:(A。)车库天花板上有一个出口。您认为有多少放大器与此出口相连(20?50?100?)可能是不可能知道的,但也许有一个标准的AMPS,公寓车库需要拥有。我认为它必须超过20个,因为如果同时开放4个车库,则断路器会绊倒。

(b。)我可以从这个出口绘制多少瓦?

(c。)如何了解车库中有多少安培?断路器在哪里找到它?

问题2:我已经设置的灯定期下调(也许当其他人打开他们的车库)。如何保持恒定的光线? (电压稳定器,在线UPS?)我不确定这些是什么,但我最好的选择是确保这些灯始终是一致的亮度?

英文原文

I have two questions that hopefully someone more experienced than me can answer.

Background: I am doing a claymation in a garage and need to set up a lighting system that requires (a.) lots of wattage and (b.) constant voltage so lighting stays extremely consistent [doesn't get dim or flicker despite other people using outlets].

The garage is connected to about 20 other garages in an apartment complex, so it is not a typical house hold garage.

Question 1: (A.) There is one outlet on the garage ceiling. How many amps would you assume is connected to this outlet (20? 50? 100?) It may be impossible to know but perhaps there is a standard amount of amps that apartment garages need to have. I figure it would have to be more than 20 because if 4 garages are opened at the same time, the breaker would trip.

(B.) How many watts could I draw from this one outlet?

(C.) How can I find out how many amps are in the garage? Where would the circuit breaker be to find it?

Question 2: The lights I have set up go dim periodically (perhaps when others open their garage). How do I maintain constant light? (Voltage stabilizer, online ups?) I'm not sure what those are, but what is my best option to make sure those lights are always a consistent brightness?

更多电流!你用什么用于照明 - 弧灯?

作为一个动画和摄影师,我自己想要尽可能酷的照明。那里有一些伟大的LED灯(或者你可以建立自己)。对于小阶段,我甚至使用LED火炬用于亮点。

LED还具有从受调节的直流电源运行的优势(绕过下垂问题)。您可以控制强度(PWM)和色温控制(LED以各种颜色)。

现代数码相机(视频和静止)在较低的光线条件下令人愉快地运行饱和的颜色良好。

只是在健康和安全点

(1)绘制比布线更高的电流,设计成大大提高火灾的风险。你真的不想引起火灾。你的灯光暗淡的事实意味着系统正在紧张地应对正常需求。

(2)热灯也可能导致火灾。特别是使用各种艺术家的材料(纸张,油漆等)

 

More current! What are you using for lighting - arc lamps?

As an animator and photographer myself I'd want to run the lighting as cool as possible. There are some great LED lights out there (or you could build your own). For small stages I've even used LED torches for highlights.

LEDs also have the advantage of running from a regulated DC supply (which gets around your droop problem). You can control intensity (PWM) and color temperature control (LEDs come in all sorts of colors).

Modern digital cameras (video and still) operate quite happily in lower light conditions giving well saturated color.

Just on a Health and Safety point

(1) Drawing a higher current than the wiring was designed to take greatly increases the risk of fire. You really do not want to cause a fire. The fact that your lights dim means that the system is straining to cope with normal demand.

(2) Hot lights can also cause fires. Especially with various artist's materials being used (bits of paper, paint etc.)

在我看来中,您的最佳选择也是最有效的:使用基于LED的集合照明。 LED基灯使用功率调节器来产生每个LED"灯" 所需的3V,并且这些稳压器(通常切换降压控制器)通常非常容易受到电力波动的波动。 LED也具有出色的寿命,通常不会随时间改变颜色(或电压!),并且不会像氙/卤素/无论旧式灯泡一样加热您的空间。甚至不会有任何可观的等待时间,如旧学校照片灯。

,你会节省电力。

LED系统可以通过200瓦的电源轻松亮起整个场景,因此从单个出口中抽出2A。

 

In my opinion, the best option for you is also the most efficient: Use LED based set lighting. The LED based lights use power regulators to generate the 3V needed for each individual LED "lamp," and those regulators (typically switching buck controllers) are usually very tolerant to fluctuations in power. LEDs also have excellent life spans, don't typically change color over time (or with voltage!) and won't heat up your space like Xenon/Halogen/whatever old-style lamps will. There won't even be any appreciable waiting time for warm-up like there is with old-school photo lamps.

And you'll save on electricity.

LED systems can easily light an entire scene with perhaps 200 Watts of power, so 2A of draw out of a single outlet.

不幸的是...

由于欧姆的法律,电压降。在您的情况下:

电压下垂电源线= 电源的平方根时间 电力线中的电阻

如果偶尔看到灯光昏暗,在那些时刻,线路上的负载太多了。

唯一的解决方案,概念上,是为系统添加更多能量。

添加能量...

UPS

UPS代表"不间断电源" 。有两种基本类型:

  1. a true UPS,其中来自墙壁的电源被转换并应用于存储设备,如电池,然后存储设备用于电源连接到它的插座的任何内容。

  2. SPS("备用电源" )直接将其插座连接到电源线,并在检测到电源线后,只需切换到电池即可不再提供足够的电源。

真正的UPS的工作,因为电源始终来自内部储备,带有或没有外部电源。 SPS的检测和交换机,这导致您的场景中的一系列问题:

  1. 存在一个不同的切换瞬态,导致亮度变化
  2. 它不会在电源线瞬态切换(通过设计)
  3. 输出(AC)功率通常具有差的质量,这将在不同的有效光强度
  4. 中表现出
不幸的是,真正的UPS非常昂贵,并且鉴于您对最大出口电力额定值的兴趣,我怀疑您需要大量的UPS来跟上您的电力需求。 你在消费电子空间中发现的每一个"UPS" 实际上是一个SPS。

发电机

我会建议您只需完全离开网格,如果您对光线水平非常敏感,则会使自己的电源。 a 2.2 KW能力发电机持续600美元(美国)。

逆变器

您也可以考虑使用DC-AC逆变器来为此目的使用汽车电池组。

祝你好运!

声音像一个有趣的项目!

 

Can't create energy unfortunately...

The voltage drops because of Ohm's Law. In your case:

Voltage droop in power line = square-root of power used times the resistance in the power line

If you see the lights dim occasionally, at those moments, there is too much load on the line.

Your only solution, conceptually, is to add more energy to the system.

Adding energy...

UPS

A UPS stands for "Uninterruptible Power Supply". There are two basic types:

  1. A true UPS in which power from the wall is converted and applied to a storage device, like a battery, and then the storage device is used to power anything connected to it's outlets.

  2. An SPS ("Standby Power Supply") connects it's outlets to the power line directly and simply switches to a battery after it detects the power line is no longer providing sufficient power.

True UPS's work because the power always comes from their internal reserve with or without external power. SPS's detect-and-switch, which causes a bunch of problems in your scenario:

  1. There is a distinct switching transient that will result in brightness change
  2. It does not switch (by design) on power line transients
  3. Output (AC) power is typically of poor quality, which will manifest in a different effective light intensity

Unfortunately, true UPS's are very expensive and, given your interest in maximum outlet power ratings, I suspect that you will need a massive UPS to keep up with your power needs.

Virtually every "UPS" you find in the consumer electronics space is actually an SPS.

Generator

I would recommend that you just go completely off-grid and make your own power if you are so sensitive to light level. A 2.2kW capable generator runs around $600 (US).

Inverter

You might also consider using a DC-to-AC inverter to use a bank of car batteries for this purpose.

Good luck!

Sounds like an interesting project!

1(a)

在美国,大多数一般的照明电路被评定为15安培,但通用容器出口通常为15或20安培。

1(b)

计算瓦数使用简单的公式来安全地提供电路。

Voltage * Current * Safety Factor = Wattage

80%是用于确保电路的公共安全系数不断地加载到100%

120V * 15A * 80% = 1440W
120V * 20A * 80% = 1920W

1(c)

几乎没有办法通过互联网回答这个问题。在房子中,您可能会遵循服务导体,并最终找到服务面板。在公寓大楼,面板可能更难以找到。在美国(或许只有一些国家),必须对租户访问专家组。因此,面板通常位于每个公寓或公共区域。

2

一个不间断电源(UPS)可能能提供更稳定的流量,虽然您仍然可能取决于单位的大量调光或闪烁。

 

1(A)

In the US most general lighting circuits are rated for 15 amperes, though general receptacle outlets are typically either 15 or 20 amperes.

1(B)

Calculating the wattage a circuit can safely supply is done using a simple formula.

Voltage * Current * Safety Factor = Wattage

80% is a common safety factor used to insure circuits are not constantly loaded to 100%

120V * 15A * 80% = 1440W
120V * 20A * 80% = 1920W

1(C)

There is almost no way to answer this through the internet. In a house you could likely follow the service conductors, and eventually locate the service panel. In an apartment building, the panel can be more difficult to find. In the US (or maybe only some states), the panel has to be accessible to the tenants. Because of this, the panel is commonly located either in each apartment or a common area.

2

An Uninterrupted Power Supply (UPS) might be able to supply a more steady flow, though you may still get a big of dimming or flicker depending on the unit.

完全取决于建筑物和该地区。没有具体的答案。也就是说,标准布线将在10到20个放大器之间。

所知的最佳方式是找到适用于您的车库的电气盒。如果电路仅适用于您的车库,那么保险丝或断路器会告诉您您可以拉动多少放大器。如果它涵盖了多个车库,那么它将至少是该熔断器的最大限度,与其他任何其他人在使用的情况下共享。瓦数是电压和电流的函数,所以再次取决于电路的内置。

对于灯光暗淡,来自车库电机的重电流绘制将导致电压下降。没有发电机或独立电路,你不能做。

 

Completely depends on the building, and the area. There wouldn't be a specific answer. That said, standard wiring will be for between 10 and 20 amps.

The best way to know is finding the electrical box that applies to your garage. If the circuit is only for your garage, then the fuse or breaker will tell you how many amps you can pull. If it covers more than one garage, then it will be atleast the maximum of that fuse, shared with whatever anyone else is using at the time. Wattage is a function of Voltage and Amperage, so again, it depends on what the circuit is built for.

As for the lights going dim, heavy current draw from garage motors will cause the voltage to sag down. Not much you can do without a generator or independent circuit.

很难说没有塞子的图片,可以告诉我们很多(你在世界上的世界,安培,等等)我会认为你在美国并猜测你的出口是120V在15a。虽然给予车库设置,但您可能有一个20a电路。再次,我们需要更多信息。最好的事情是要检查插头的评级并检查它连接到其评级的断路器。如果假设是正确的(120V @ 15a),则可以从此出口中拉1800W。我猜测公寓大楼不打算让你使用这个插座,它只是为了车库门开启者(因此在上面的单个出口)。为此,您可能不会找到断路框盒。

您的电路显然是与其他车库相关联,因此在绊倒断路器之前,您可以挤压多少电流并不像我上面所概述的那样微不足道。例如,乔隔壁可能会在他的车库里给他的全新电动汽车充电。他的车和你的照明可以单独绊倒破碎机......这将留下一些邻近的邻居,他们不能把他们的车停在车库里。 :)

不幸的是,我想不出一种在便宜的方式保持一致亮度的方法。其他人可以在这里聊天。本质上是发生的事情是你的邻居发射他们的车库门开启器,这导致过量的电流在分支上流动,导致电压降。此电压降为您的闪烁。
 

It's difficult to say without a picture of the plug which could tell us a lot (what part of the world you are in, amperage, etc.) I will assume that you are in the US and guess that your outlet is 120V at 15A. It's possible you have a 20A circuit though given the garage setting. Again, we would need more information. Best thing to do would be to check the plug for its rating and examine the breaker it is connected to for its rating. If the assumption is correct (120V @ 15A) you could pull 1800W from this outlet. I am guessing that the apartment complex does not intend for you to use this outlet and it's solely there for the garage door opener (hence a single outlet above). You probably won't find the breaker box for this reason.

Your circuit is obviously tied to others garages and so how much current you can squeeze before tripping the breaker is not as trivial as what I outlined above. For example, Joe next door might be charging his brand new electric car in his garage. His car along with your lighting could be enough to trip the breaker alone... which will leave a few of your neighbors upset that they can't park their car in their garage. :)

Unfortunately I can't think of a way to maintain a consistent brightness on the cheap. Others may chime in here. Essentially what's happening is your neighbor fires up their garage door opener which causes excess current to flow on the branch resulting in a voltage drop. This voltage drop is visible to you as flicker.

在那里有一些非常漂亮的功率调节器,实际上可能为您的需求做出足够的电压调节。 Furman Products春天思考。好的是昂贵的。我将在

 

There are some pretty nifty power conditioners out there that might actually do sufficient voltage regulation for your needs. Furman products spring to mind. The good ones are pricey. I'll refer you to their educational video page at http://www.furmansound.com/page.php?div=01&id=TECH
