110伏电压和220伏电压,哪个更科学?

只要出过国的朋友想必都知道,某些国家的电器额定电压是110V,而并非我们中国的220V。这时我们禁不住要问:难道电压也分国界?不同的国家都不一样?220V只是中国特色,别的国家都用110V?

110伏电压和220伏电压,哪个更科学?

让我们先来看一组各国民用电的电压情况:

【100V】

两个国家——日本、 朝鲜

【110~130V】

约30个国家(地区)——美国、加拿大、墨西哥、古巴、黎巴嫩、巴拿马等国和中国台湾等地区

【200~230V】

约120个国家(地区)——中国、英国、法国、德国、意大利、印度、中国香港(200V)、西班牙、荷兰、奥地利、菲律宾、挪威、泰国、新加坡、纽西兰、澳洲各国等(部分采用220~230V电压的国家,也有因地区不同并用110~130V电压的情况,比如俄罗斯和瑞典)

由上可以看出,目前全球各国的电压各不相同,主要以110V和220V为主。那么110V电压和220V电压,到底哪种电压更科学呢?让我们从以下几个方面来解读:

一、历史性

稍微了解电力历史的应该都知道这两个人:一个叫爱迪生,一个叫特斯拉。在电力使用早期,爱迪生的通用电力公司在美国普及110V供给直流电。随后特斯拉发明了三相交流电,三相的意思是有三个不同相位的电力合并在一起以减弱供电中的电压波动。交流电压一开始是3相的240V的,出于安全考虑,才把电压降到了110V。

110伏电压和220伏电压,哪个更科学?

在两大天才爱迪生、特斯拉就“直流强还是交流强”的问题争论一番后
