Description

technical field [0001] The invention relates to the technical field of energy saving, in particular to a general-purpose intelligent power-saving device. Background technique [0002] With the rapid growth of my country's power energy consumption, energy saving has become a long-term strategic issue related to my country's national economic security, international market competitiveness of enterprises, resource and environmental protection and other economic and social sustainable development. For many years, all parts of the country have been in a state of unprecedented tension in electricity consumption. Due to the rapid economic development directly leading to a sharp increase in electricity consumption, the power supply has been tightened in an all-round way. Serious, at the same time, the electricity bill is usually the third largest cost of the enterprise unit, but it is a very staggering cost for the enterprise. Now the enterprise has generally realized that the use o...

Problems solved by technology

At present, there is a common situation of poor power quality in the power supply grid. The rapid development of the social economy and the use of various new electrical equipment make this situation more serious, which has a great impact on the user's electrical equipment. The most direct performance Because the equipment is not working properly, the life is short, the electricity bill is high, the efficiency of the transformer is low, etc.

In the power consumption systems of general administrative institutions and industrial and commercial enterprises, there are mostly small loads, the working conditions are different, the power factor is generally not high, there are many kinds of power consumption equipment, and the use of a large number of electronic devices and switches reduces the power quality. ;In the power system, problems such as equipment configuration, line laying irregularities, and line aging have increased line losses; when enterprises develop new equipment, they are limited by the capacity of transformers with low output, and the pressure for capacity increase is high. Large, large power loss
