Abstract

The invention discloses a low-voltage magnetic ring reactor and a production process thereof, and belongs to the technical field of reactors. The low-voltage magnetic ring reactor comprises an aluminum-coated zinc board shell, wherein connecting parts are arranged on the lower parts of the front and back side surfaces of the aluminum-coated zinc board shell, and the surface of the side edge of the aluminum-coated zinc board shell is provided with a right-angle covered edge; the inner surface of the aluminum-coated zinc board shell is provided with an insulation plate, and an interstitial effect among particles of a sendust magnetic ring leads to the characteristics of low magnetic permeability and constant magnetic permeability; besides, since the particle size of the material of the reactor is small, the chance of the occurrence of a skin-effect phenomenon is reduced, the magnetic permeability becomes more stable with the change of frequency, and the loss of of the reactor is lower than an ordinary iron powder core by 80% so that the reactor can be used at frequency above 8 kHz; the saturated magnetic induction is about 1.05 T, the magnetic permeability is 26-125, and the magnetostrictive coefficient is close to 0; the working noise which is generated at different frequency is small, and the output inductance is more stable than that of a traditional silicon steel sheet material.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a low-voltage magnetic ring reactor and a production process thereof. Background technique [0002] With the development of the national economy, the loads of various industries and civilians have increased significantly, and the reactive load current in the newly added loads has increased the loss of the power supply system, affecting the power quality, voltage quality and operation safety of the power system. Usually in the power supply system Capacitor compensation cabinets are used for reactive capacity compensation to improve the stability of the power supply system. In the capacitance compensation circuit, reactors are usually connected in series to reduce the inrush current when the capacitor is put into operation, and can also block high-order harmonics from entering the capacitor, thereby prolonging the service life of the equipment and protecting the safe operation of ...
