Three-phase electromagnetic balancing energy-saving electric reactor

Abstract

The invention discloses a three-phase electromagnetic balancing energy-saving electric reactor. The three-phase electromagnetic balancing energy-saving electric reactor mainly consists of coils (1), core limbs (2), an upper iron yoke (3), a lower iron yoke (6) and a tightening bolt (4), wherein the coils (1) are arranged on the core limbs (2) in a sleeving mode, clamped between the upper iron yoke (3) and the lower iron yoke (6), and fixed by tightening the upper iron yoke (3) and the lower iron yoke (6) through a tightening bolt (4). During usage, the three-phase electromagnetic balancing energy-saving electric reactor is in series connected in a to-be-governed power grid of an electric power system without special operation needs and quick-wear parts, so that the application is convenient and the operation maintenance cost is low. The three-phase electromagnetic balancing energy-saving electric reactor can be manufactured into a dry-type structure and also can be manufactured into an oil-immersion structure, is simple in structure, high in practical performance, easy for large-scale production, convenient to dismount, and easy to maintain; an arrangement structure of the core limbs is in the shape of an equilateral triangle, three magnetic paths are consistent in length, shortest, and are equal in three-phase magnetic resistance; a three-phase coil is arranged on each magnetic pillar, and therefore, the magnetic resistance is relatively balanced and the loss is low. The three-phase electromagnetic balancing energy-saving electric reactor can be widely applied to balancing a three-phase power supply phase angle in electric systems of factories, authorities, residential areas and the like, increasing a system utilization rate, and lowering harms of impact and waveform distortion of large-power equipment operation to the power grid, so that purposes of saving energy and operating safely are achieved.

Description

technical field [0001] The invention belongs to the category of electric power energy saving and relates to a reactor, in particular to a three-phase electromagnetic balance energy saving reactor. Background technique [0002] With the rapid development of social industry, high-power impact loads and the widespread use of rectifier and frequency modulation equipment have caused hazards such as fluctuations, flicker, and waveform distortions in the grid voltage of the system, seriously affecting the safety of power equipment and electrical equipment, as well as three-phase imbalance, Therefore, the reactive power balance in the power grid is very important to improve the quality of power supply, improve the economic benefits of the whole network and the reliability of power supply. Because the wire wraps of traditional reactors are arranged in a planar structure, single-phase wire wraps are arranged on each magnetic column, which has the disadvantages of unbalanced three-phas...
