By replacing coils with different turns ratios, different flexibility requirements for voltage and current adjustment and harmonic suppression can be met.

[0022] A plurality of heat dissipating fins 4 distributed at equal intervals are installed at the opposite ends of the two heat conducting plates 2. The heat dissipating fins 4 are made of metal copper and are installed and fixed to the heat conducting plates 2 by welding. When the reactor unit 1 is working, a large amount of heat is generated. The heat enters the heat dissipating fins 4 through the heat conducting plates 2, so that the heat is fully dissipated by contacting with the outside air, thereby achieving heat dissipation.

A first mounting through hole is penetrated on the mounting frame 5. The first screw penetrates the first mounting through hole. The first screw is threadedly connected to the first nut. A fixing plate 8 is fixedly connected to the side wall of each mounting frame 5. Two second fasteners 9 are installed on the two fixing plates 8 on the same side. The second fasteners 9 include a second screw and a second nut. A second mounting through hole is penetrated on the fixing plate 8. The second screw penetrates the second mounting through hole. The second screw is threadedly connected to the second nut. The two mounting frames 5 on the upper and lower sides are reinforced by the first fasteners 6. The two fixing plates 8 are installed and fixed by the second fasteners 9 to complete the installation and disassembly of the reactor unit 1 and replace different turns ratios.

[0025] In the utility model, the staff can rotate and remove the second nut by using a tool such as a wrench, separate the second screw rod from the second nut, and then separate the upper and lower heat conduction plates 2, and then remove the reactor unit 1, and replace the turn ratio of different coil numbers to meet different usage needs.

[0026] The utility model solves the problem that a large amount of heat is generated by the reactor in the prior art when it is working, and if the heat cannot be discharged in time, the electrical components thereon will be damaged, and the existing reactor cannot meet the flexibility requirements of modern power systems for voltage and current adjustment and harmonic suppression.
