Description

Technical field [0001] The present invention relates to the technical field of power equipment, in particular to a voltage stabilizing energy-saving device. Background technique [0002] For most factory power grids, the voltage of the 6KV power grid is generally between 6.2KV and 6.5KV, especially during the low time period of the power grid at night, which may be above 6.7KV, while the 10KV power grid is mostly between 10.3 and 10.6KV. The situation, for those large-scale power installations with light load and underload, the waste of electric energy and the harm caused to the electric equipment itself cannot be ignored. To solve this common operation problem of electric equipment, it is necessary Research is necessary to provide a reliable, efficient and economical solution. Summary of the invention [0003] The problem to be solved by the present invention is to provide a voltage stabilizing energy-saving device with simple structure, reasonable design, stable and fast action...
