供配电技术学习心得体会（Learning experience of power supply and distribution technology） Learning experience of power supply and distribution technology With the development of economic construction, Chinas current urban construction is developing rapidly, and its scale and scope are unprecedented. For the distribution of this class is mainly about the introduction to power system, load calculation, short-circuit current calculation, power and a mating system, power equipment selection, power line relay protection, power supply system, substation secondary circuit two and automatic device, electrical safety, lightning protection and grounding, electrical lighting. The operation and management of power supply and distribution system. As is known to all, electric energy is the main energy and motive force of modern industrial production. Power is easy to convert from other forms of energy, but also easy to convert to other forms of energy supply; the distribution of power transmission is simple and economic, and easy to control, regulation and measurement, is conducive to the realization of the production process automation. Therefore, electric energy is widely used in modern industrial production and the whole national economic life. In the factory, electric energy is the main energy and power of industrial production, but its proportion in the product cost is very small (except for the electrochemical industry). The importance of electrical energy in industrial production does not lie in its cost or total investment The amount in the proportion of the number, but in industrial production after electrification can greatly increase production, improve product quality, improve labor productivity, reduce production costs, reduce labor intensity, improve the working conditions of workers, conducive to the realization of the production process automation. On the other hand, if the power supply of the factory is suddenly cut off, it may have serious consequences for industrial product
