当电力在大型风暴或公用事业公司中断期间熄灭时,我们中的许多人都意识到我们对电力的依赖程度。毕竟,电力几乎为我们家中的每个设备和技术设备提供了光和功率。结果,如果没有电力,我们的房屋就不仅仅是庇护所。我们坐在黑暗中,想象我们的冷冻食物解冻,并为更长的手机和笔记本电脑电池寿命祈祷。

这就是为什么应急发电机变得有意义的原因。发电机可以提供足够的电力,以保持我们的家庭运转,直到电力回报为止。在大规模停电的情况下,手头有便携式电气发电机可以帮助您的家庭度过风暴。拥有一定的电力可能会使您有几个灯光,制冷,燃气热水器的热水和一个工作的燃气炉。

Buying the Best Portable Emergency Generator

如果您居住在停电很少但有时会发生的区域,那么便携式应急发电机可能是您需要的全部投资。它可以使冰箱和冰箱运行,或者使您能够打开一些灯并运行微波炉和计算机,以便您可以生存几天而不会造成任何严重损失。

Choose a generator made specifically for household use rather than a worksite or camping generator. Consider how much power and what sorts of plugs you will need. Also consider the quality of the machine and how easy it will be to start and maintain.

发电机的注意事项

Here are the features you should consider when making a choice:

电力发电机将交付

Generators are sized according to the number of watts of electrical power they deliver. In addition to the power a generator supplies while in constant running mode, a generator also should supply short bursts of “surge” power, which is needed for a few seconds to start up a large appliance such as a refrigerator or a clothes dryer.

A small generator delivers 3,000 to 4,000 watts—enough to supply a medium-sized refrigerator, a few appliances, a TV, and some lights. If you want a more civilized life, up the wattage to 5,000 to 6,000 watts and you’ll be able to add a window air conditioner or two, a freezer, and more appliances. Large generators that deliver 7,000 to 10,000 watts enable you to run just about everything in a medium-sized house, minus a central air conditioning system.

Type & Number of Electrical Plugs a Generator Has

小型便携式发电机可能只有12伏插头,适用于标准延伸线,并且能够运行灯光和小型到中型电器。如果您需要为240伏设备供电,请确保发电机具有合适的插头。如果您通过转移开关将生成器插入房屋(请参阅Standby Generators & UPS Backup Batteries), there must be a special four-slotted plug that supplies both 120 and 240 volts.

将为发电机供电的燃料类型

大多数廉价的发电机仅在汽油或柴油燃料上运行,并且可能只能容纳几个小时的燃油箱。选择一个足够大的储罐的型号,以便整个晚上都可以奔跑。还考虑可以转换为丙烷罐或房屋的天然气管线的发电机。

Generator’s Motor & Starting Method

一些低端发电机开始使用拉动绳,就像老式的割草机一样。高端型号具有电池供电的电动启动器。显然,按下启动按钮要比拉起绳索容易得多。还要考虑需要什么才能使它们保持运行。必须启动一些电动机并每月或两分钟跑步,而另一些电动机可以持续一两年而无需跑步。

Generator’s Grounding Method

Nearly all modern generators do not need to be grounded (connected to a grounding rod driven into the earth or to a metal water pipe). For safety, check the owner’s manual to ensure the model you choose does not need to be grounded.

设置便携式发电机

大多数便携式应急发电机需要适度的组件,包括安装轮子。您还需要添加制造商推荐的类型的油。通常,如果您希望在寒冷的天气下使用发电机,请加入5W-30油;要在中度到炎热的天气中跑步,请使用10W-30。另外,请确保使用推荐的燃料类型 - 例如,许多型号要求无铅汽油,其辛烷值等级为85或更高,不超过10%的乙醇。

未雨绸缪

Remember that It will be much easier to do all the gathering of equipment and set-up when you have power—especially if an outage should occur after dark. Before you need to run the generator, plan where you will place it in the event of an outage, and determine where you will run the extension cords. Make a list of the appliances and lights you want to power in case of a power outage, and add up their wattages to make sure you will not overload the generator.

Never run a gas motor inside the home- 它产生有害的一氧化碳烟雾,可能是致命的。它可以在露台,开放式门廊或车道上或其他无人空间的通风附属建筑物上运行。

Also be aware that the generator’s noise can be irritating so, if possible, place the appliance out of earshot. Don’t plan to put the generator where it might be vulnerable to rain. Though generators can run for a short while in light mist, a downpour may render them inoperable.

Test Your Gear

Test the lengths of extension cords to be sure they will reach where you need them to and store them near the generator. Store plenty of gasoline or other fuels in safe containers that are easy to access.

Be sure to use heavy-duty extension cords, not lightweight household cords. Cords should, at a minimum, have 12-gauge wire; 10 gauge or thicker is preferable. Check the cords for condition, with no nicks in the insulation or exposed bare wire.

电气服务面板

Do not attempt to hook up a portable generator to your home’s electrical service panel. This type of generator is designed to supply a limited amount of power via extension cords. If you want a system that automatically supplies power during an outage, hire a professional to install a standby generator (see便携式应急发电机的替代方案).

如果您希望发电机在房屋中的某些容器和设备中供电,而无需多个扩展线,请让电工在房屋的主服务面板中安装传输开关。安装此传输开关后,您只需将发电机插入其中即可为指定的电路提供电源。仅插入您要使用的设备和灯。

How to Run an Emergency Generator

Before running an emergency generator, read the article设置便携式发电机(above). If you take the steps suggested in that article, you’ll be much better prepared to get the generator up and running quickly and easily.

When setting up the generator, check the oil and fuel levels and top them off as needed. Roll the generator to the dry, well-ventilated place that you’ve chosen, and gather together the various extension cords you’ll need.

Start the generator before you attach the extension cords. Plug in the cords and then run them into the house. Though the cords can get wet, keep any connections—for example, where you plug together two cords—dry. Adjust the motor’s speed as needed to sustain the appliances or lighting you want to power.

Consult your owner’s manual to determine how long the motor will run before you need to refuel so you can anticipate the need to refuel. When you do refuel, first turn off the motor and unplug the cords. Wait a few minutes for the motor to cool down before adding the fuel.

If the power outage might last days rather than hours, plan your energy usage so you can give the motor a rest. Run the refrigerator or freezer only sporadically, and keep its door closed as much as possible.

If possible, run a generator only one- quarter to one-half of the time. You might, for example, turn it off when everyone has gone to bed. Exceptions include a sump pump that needs to run continuously to clear out water in the basement or a furnace or gas boiler needed to heat the house on very cold nights.

维护便携式发电机

在停电期间,没有什么比将便携式应急发电机赶出来更令人沮丧的,只是发现它不会运行。

在您不需要的几周或几个月中,保持发电机可操作至关重要。如果您通常只在蓝色月亮中使用一次发电机,请强烈考虑为其购买盖子以保护其免受天气和碎屑的侵害。

First, consult the owner’s manual for proper maintenance directions so you can be confident the motor will start up when you need it. Manuals typically advise:

• Periodically cleaning and/or changing the spark plugs

• Cleaning the screen on the spark arrestor

• Maintaining a sufficient amount of oil

• Changing the oil after a specified number of running hours

• Periodically cleaning and/or changing the air filter

If you will not be starting a portable generator for more than a month, add fuel stabilizer to the tank to keep the carburetor from getting gummed up. Many manufacturers recommend that you run the motor for about 10 minutes every two to three months.燃油稳定剂can be found on Amazon.

If your generator has an electric starter, be sure to keep the battery charged so the generator will start when you need it. (If the battery does run down, most models allow you to start the generator with a hand pull.)

保持发电机清洁。盖上它以保持干燥。如果需要清洁,请避免使用软管;使用软刷,或用几乎湿布擦拭。
