Through the use of energy-saving equipment and power-saving technology, enterprises can save more than 20% of electricity. Relevant research shows that 50% to 70% of the world's total energy is wasted due to existing energy-consuming equipment and methods. High technology turns power saving into a possible and effective means, and technological advancement turns potential demand into real demand. In the field of power saving, a series of new technologies such as capacitor compensation and variable class have been introduced to improve energy utilization. To this end, governments and enterprises have carried out a lot of useful explorations, made painstaking efforts, and took out extremely valuable experience. The power-saving industry is still a strange industry for most people. However, in foreign countries, the development of the power-saving industry has been for decades. As early as 1972, the United States began to appear motor power-saving technology, system power-saving technology has been available in 1975, and lighting power-saving technology was developed in the western developed countries in the early 1980s. Its first generation of power-saving technology is capacitor compensation. It was produced in the 1950s. The power-saving effect is not obvious but it is harmless. It is a mandatory promotion by the government. After years of development, the power-saving space for various types of power system technology is very small. The technology that was eliminated; the second-generation power-saving technology is the thyristor chopper technology, which was produced in the 1970s. The power-saving effect is obvious but it is very harmful. After the promotion of general enterprises, the power-saving rate has been improved, but it cannot be guaranteed. It can effectively save electricity and has no harm to the power grid and equipment. Therefore, lack of government support is facing the fate of being eliminated. The third generation of power-saving technology is frequency conversion technology, which was produced in the 1980s and 1980s. But the damage is very big, the internal is the reliability of electronic components; the fourth generation of power-saving technology to suppress surge technology, produced in the 1980s, the power saving effect is not obvious, it is difficult to test, but the circuit can be cleaned; the fifth generation festival The electric technology is electromagnetic conversion and compensation. It was produced in the 1990s, and the power saving effect is obvious, harmless and the circuit can be cleaned. The perfect combination of power saving effect and grid quality has been achieved.
