电表仪器的种类和用途我们是生活在电气时代中,电在我们的日常生活中,起着重大的作用。在工业中电是主要的原动力,在国民经济的其他部门使用电作为原动力和用来控制机器,也日益普遍。在日常生活中,照明用电灯、加热用电炉,以及无线电广播、电报、电话、电影等等,也都需要电。总之,电已经和我们生活的各方面发生了密切的联系。但是,由于电是一种很强的动力,如果我们对它不能够控制或者控制不好,就会带来很大的祸患。比如,由于夏季天空中的雷电、高压的电源及电力线路的损坏,往往会发生人畜触电死亡、失火及设备烧毁等事故。电是用眼睛看不见的,又不能用手摸,人们完全要依靠电表仪器一类的器械来控制它。电表仪器是一
The types and uses of electric meters We are living in the age of electricity. Electricity plays an important role in our daily life. In the industry, electricity is the main driving force. The use of electricity as a motive force and control of machinery in other parts of the national economy is also becoming increasingly common.

For example, due to the damage of thunder and lightning, high-voltage power and power lines in the summer sky, accidents such as electrocution of humans and animals, misfires, and equipment burn-out occur. Electricity is invisible to the eyes, and it cannot be touched by hand. People completely rely on instruments such as electric meters to control it. Electric meter instrument is a
