Prepaid energy meters share basic knowledge of electricians
Shandong University of Science and Technology Zhongtian Electronics Co., Ltd. specializes in single-phase electronic energy meters, prepaid energy meters, DF multi-user smart meters, multi-user energy meters, electronic meters, apartment ** energy meters, high-current centralized meters, and Production and sales of multi-user smart meters.
Electricity is indispensable in people's daily life. At the same time that electricity fights bring convenience, there are hidden dangers in use. Therefore, we must master the basic knowledge of electricity in order to make better use of it, especially electricians. I will share with you the basic knowledge of electricians.
There are three easy ways to learn electricity. One is the combination of theory and practice, which is easy to learn; the second is a solid foundation, which is easy to learn; the second is to be proficient in one specialty and easy to learn other majors.
1. Basic knowledge of electrical engineering and basic knowledge of electronic technology is the foundation of the electrical industry and the source of continuous improvement.
2. Power system knowledge and common sense of electricity use are the basic knowledge of the power industry and the guarantee of life and safety.
3. Electrical engineering, substations, transformers, etc., primary part, secondary part, theory, principle, application, etc., it is good to learn well and learn well.
4. The most important thing in the electrical industry is to quickly integrate theory with practice. It is important to remember the four easiest things. One is the combination of theory and practice, which is easy to learn; the second is a solid foundation, which is easy to learn; the second is to be proficient in one specialty, and easy to learn other majors;
A power source is a device that continuously converts other forms of energy into electrical energy. It does not create energy or charge. For example, a dry cell is a device that converts chemical energy into electrical energy, and a generator is a device that converts mechanical energy, nuclear energy, etc. into electrical energy.
The voltage or current whose size and direction change periodically with time is called alternating current.
