Description
technical field [0001] The invention relates to the field of pressure regulating devices, in particular to a low-energy and energy-saving bypass stepless pressure regulating device. Background technique [0002] The voltage qualification rate is one of the important assessment indicators of voltage quality, and it is also the most intuitive indicator of user voltage quality. The voltage qualification rate has a direct impact on the stability of the power system, the safe operation of power equipment, the safe production of industry and agriculture, and the electricity consumption of people's lives. Today, as our country has undergone reform and opening up, the economy has taken off rapidly, people's living standards have continued to improve, and household appliances have entered people's lives. The original power distribution network has been unable to meet the demand for electricity. Influenced by factors such as long radius and uneven load distribution, the line voltage f...
