如果家里停电了，你会如何应对? Do you have a stockpile of flashlights and candles, just in case? How will you prepare meals or run water when the electricity has gone out?

Although the typical power outage in Maryland does not last for very long, 这是有可能的权力 连续出去好几天. 如果发生这种情况，做好准备是值得的. One way to protect your home and family is to install a 备用发电机 on your property. 了解更多关于备用发电机的好处，以及如何为您的家选择发电机. 

什么是备用发电机?

A 备用发电机 是否连接到你的电气系统, 它的设计原理是，一旦家里的主要电源被切断，它就会启动并为你的家提供电力. 备用发电机不同于其他类型的发电机，它是永久安装的，通常连接到天然气管道或丙烷罐. 如果你有备用发电机，它会在家里断电时自动启动. You will not have to go out and fill it up with fuel or switch on the motor yourself.

Standby generators are just one type of generator or backup power source. 其他电源选择包括便携式发电机和逆变器. Inverters and portable generators typically provide less power than home 备用发电机s. 一台大型的便携式发电机也许可以提供电力 高达7500瓦, which would keep many, but not all, of the appliances in a typical home going. 一台备用发电机通常可以供应大约20台,000瓦的电力——足够让现代家庭中的所有电器运转. 

如果停电很少，或者在户外活动中需要电力，便携式发电机是一个很好的选择. 然而, 备用发电机是理想的，如果你正在寻找一个随时准备的备用电源为你的整个家. 例如, if someone in your home uses medical equipment that always needs to be on, a generator ensures the power to that equipment will not be cut. 另外, 如果你家里有小孩或老人, they tend to be more sensitive to excessively hot and cold temperatures. 发电机可以帮助他们保持舒适的加热器或空调机组运行. If you live in an area that has been affected by extreme weather events in the past, 比如飓风或暴风雪, 发电机可以给你带来更多的平静.

家用备用发电机有多种尺寸可供选择. 适合你家的尺寸取决于在停电的情况下你需要多少家电设备来维持运行, 而不是你家的面积. 备用发电机以千瓦(kW)计量。. The size of the generator refers to how many kilowatts of power it produces. A 6kW generator can provide 6 kilowatts (or 6,000 watts) of power. A massive, 150kW generator will provide 150 kilowatts of power (or 150,000 watts).

备用发电机如何工作

如其名, 一旦安装在您的财产, 一台备用发电机正在待命, 等待它闪耀的时刻. 发电机连接到家里现有的电线和一个自动转换开关. 在正常情况下, 自动转换开关保持电力从主电源流经家庭.

如果主电源停止供电，自动转换开关就自动启动. It switches the power supply from the utility company to the 备用发电机. The generator powers on and starts delivering electricity to your home. 整个过程只需要几秒钟, 这意味着你可能在黑暗中待不到10秒, 然后一切都会恢复并快速运行. 一旦电力再次从公用事业公司流出, the automatic transfer switch senses it and once again changes the source of power, this time away from the generator and back to the utility lines.

一旦备用发电机不再需要, 它关闭电源并回到待机模式, 等待下一次需要它的时候.

For the most part, you do not need to worry about refueling your home’s 备用发电机. If you use natural gas to heat your home or power your water heater or stove, 你可以把备用发电机接到煤气管道上. 发电机随时都有燃料，只要燃气管道保持连接.

Another option is to connect your generator to a supply of propane. If you use propane to heat your home and water and to power other appliances, 让它为备用发电机供电是有意义的, 也. 注册 自动丙烷交付 将有助于确保你的发电机和其他家用电器始终有足够的燃料供应.

购买备用发电机的五个理由

需要发电机吗?? 如果您曾经经历过持续几个小时以上的断电，那么答案是肯定的. A 备用发电机 offers many benefits, which can help to offset its upfront cost.

1. 在停电期间提供舒适和保护

For the first little while, a power outage at home can seem like a fun adventure. You and your family might race around the house looking for flashlights, candles and lanterns. 如果一两个小时后还没有恢复供电, 然而, 这种冒险很快就会变成一种不便:

• 这取决于你用的炉子和烤箱的类型, you will not be able to cook or even boil water when the power is out. 
• 你不想打开冰箱或冰箱门, 因为你想让尽可能多的冷空气进入它们. 
• 在一些家庭, you may not be able to flush the toilet or have access to hot water during a power outage. 
• You cannot watch TV or use a desktop computer without a source of electricity. 
• You will eventually need to charge devices such as a laptop and smartphone. 

有了备用发电机，你不需要在停电期间暂停你的生活. 因为自动转换开关立即将电力从公用线路转移到你的发电机, 你将能够继续你的日常活动, 基本上没有中断. 

在家里安装一个备用发电机也可以帮助你和你的家人在停电时保持舒适. 如果你在夏季风暴中失去电力, 发电机将使你的空调继续运转. 在寒冷的月份应该停电吗, 发电机将提供电力，使你的热泵或其他类型的加热系统运行.

最后, 发电机可以帮助保护你的家，使必要的设备在暴风雨中运行. 如果你有一个污水泵, 例如, 发电机可以继续为它供电, 这样你的地下室就不会被淹了. The generator will also keep your well pump going so that you have a source of clean water.

2. 在飓风和风暴期间提供心灵的平静

Gearing up for hurricanes, tropical storms and other extreme weather events can be stressful. You not only want to make sure you have an adequate supply of food, 水和其他必需品, but you also want to make sure your home will be able to withstand any damage from the storm. 

拥有一台可以在紧急情况或断电时使用的发电机可以让你心平气和. You no longer need to worry about preparing for a potential loss of power, 如你所知，你的发电机将在那里填补电力公司的供应被切断的缺口. 你的房子里有一台备用发电机, 在飓风季节，你就少了一件需要担心的事情. 

3. 随时准备出发

If you are wondering whether you should buy a portable generator or a 备用发电机, 这有助于考虑它们是如何获得动力的. 而便携式发电机可以为特殊活动或户外活动提供方便的电源, 如果您正在寻找在停电事件中可靠的备份，那么它可能不是最好的选择. While you can connect a portable generator to an automatic transfer switch, 这样做通常是非常昂贵的. You also need to manually flip the switch yourself when you use a portable generator. Portable generators typically run on gasoline 也, so they will need regular refueling.

备用发电机连接到你家，一旦电力供应被切断，它就会立即启动. 你不需要扳动开关，因为它感觉到能量的损失，并为你进行转换. 当你的家恢复供电时, the transfer switch changes back to the primary power source automatically. 

备用发电机的另一个好处是，你通常不需要关注燃料水平. 如果它连接到天然气管道, the source of fuel will be provided automatically by your local gas company. 如果你的发电机是由丙烷驱动的, keeping your home’s propane tank full will ensure the generator always has enough fuel.

4. 帮助您避免断电造成的经济损失

美国的普通家庭.S. 经历 1.每年停电3次, and the average duration of a power outage is around four hours. 即使停电只持续几个小时，最终也会让房主损失一大笔钱. 如果你停电了，冰箱里装满了食物, 例如, 如果停电持续几个小时或几天，食物很可能会变质. You will need to replace the spoiled food, increasing your grocery bill for the month. 

持续的断电也会带来额外的成本. 当你没有电，你的家可能不适合居住，直到电力恢复. Unless you have friends or family members nearby who can open their homes to you, you will most likely need to pay for a hotel or other accommodations until power returns. 这取决于你住的酒店类型, 一年中的时间和停留的时间, 你可能要花几百美元甚至更多. 

A power outage can also increase the risk of damage to your home, from pipes that burst to flooding that occurs when the sump pump stops working. 不需要太多的水就会发生重大的破坏. 只要一寸水就能造成 损失高达两万五千美元. 

Having a 备用发电机 on your property will ensure your sump pump keeps pumping, the heat keeps flowing and your refrigerator remains operational, reducing the cost and risk of financial loss after a power outage.

5. 可以减少你的房屋所有者的保险费用

备用发电机可以提供另一个经济效益:安装一个可以意味着你的保险公司愿意降低你的房主的保险费. 你的房屋所有者的保险可能需要支付一些金额，以覆盖与风暴和电力损失相关的损失. 有一个发电机永久安装在您的财产减少昂贵的损害风险, 这可能会降低保险公司的成本. Many insurance companies are happy to pass on some of that cost savings to you, 以降低保费的形式. 

联系你的房屋所有者的保险公司，看看它是否提供折扣或保费减少的人谁有备用发电机. 在你购买和安装发电机之前, it is a good idea to verify your insurance company’s requirements. 保险公司很可能会要求你出示证明，证明发电机是永久性的，而且是由专业人员安装的. 如果有折扣，可能会减少您的保费 高达10%.
