Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to an explosion-proof reactor. Background Art

[0002] Reactors are also called inductors. When a conductor is energized, it will generate a magnetic field in a certain space it occupies, so all current-carrying conductors have inductance in a general sense. However, the inductance of a long straight conductor with electricity is small, and the magnetic field generated is not strong. Therefore, the actual reactor is a wire wound into a solenoid, called an air-core reactor; sometimes, in order to make this solenoid have a larger inductance, an iron core is inserted into the solenoid, which is called an iron-core reactor.

[0003] The existing patent (application number 202321722993.4) ​​discloses an explosion-proof reactor, including a mounting plate, an aluminum alloy bracket, a protective column, an iron core, a winding coil, a locking bolt and a hanging ring. Aluminum alloy brackets are fixedly installed on both sides of the top of the mounting plate, an iron core is fixedly installed on the top of the two aluminum alloy brackets, a winding coil is arranged between the two iron cores, and a top plate is arranged on the top of the iron core.

[0004] The above patent provides better heat conduction for the iron core by setting an aluminum alloy bracket, but it can only dissipate heat passively. Especially in underground reactors, it is more likely to accumulate heat and rise in temperature, which results in a general heat dissipation effect of the reactor. In addition, the environment underground is also relatively harsh, and the reactor is easily scratched by external sharp objects, which affects its service life. Utility Model Content

[0009] Preferably, the heat conduction device includes a No. 1 aluminum alloy bracket and a No. 2 aluminum alloy bracket, and the No. 1 aluminum alloy bracket and the No. 2 aluminum alloy bracket are both installed with two No. 1 screws on their upper ends, and the No. 1 aluminum alloy bracket and the No. 2 aluminum alloy bracket are respectively installed on the right part and the left part of the lower inner wall of the protective box body by the No. 1 screws. Since the aluminum alloy block has better thermal conductivity than iron, and the aluminum alloy bracket wraps the iron core, the heat of the iron core can be easily, directly and over a larger area.

[0010] Preferably, the heat dissipation device includes a fixing seat, two No. 2 screws are installed on the right end of the fixing seat, a heat dissipation fan is fixedly installed on the left end of the fixing seat, and the fixing seat is installed on the right inner wall of the mounting frame by the No. 2 screws. The heat dissipation fan rotates to blow air, and the wind blows into the protective box body, thereby accelerating the air circulation speed at the outer surface of the reactor, thereby actively dissipating the heat of the reactor.

[0011] Preferably, the No. 1 screws have the same size as the No. 1 screw holes and are positioned correspondingly up and down.

[0012] Preferably, there is a gap between the heat dissipation fan and the mounting frame.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1.

The protective box body is used to protect the reactor, reduce the scratches it receives underground, and improve its use effect.

[0015] 2. Through the design of No. 1 aluminum alloy bracket and No. 2 aluminum alloy bracket, since the thermal conductivity of aluminum alloy block is better than that of iron, and the aluminum alloy bracket wraps the iron core, the heat of the iron core can be discharged more easily, more directly and over a larger area. In addition, the cooling fan on the heat dissipation device rotates to blow air, and the wind blows into the protective box, thereby accelerating the air circulation speed at the outer surface of the reactor, and actively dissipating the heat of the reactor. The dual heat dissipation of the aluminum alloy bracket and the cooling fan can quickly cool the iron core. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The left and right parts of the lower inner wall of the protection box body 1 are provided with two No. 1 screw holes 10, the lower front end and the lower rear end of the protection box body 1 are fixedly mounted with support plates 11, and the right ends of the two mounting frames 6 are provided with two No. 2 screw holes 12. The No. 1 aluminum alloy bracket 20 and the No. 2 aluminum alloy bracket 21 are installed in the protection box body 1 by means of No. 1 screws 22, so that the winding coil 4 is also fixed in the protection box body 1, and the protection box body 1 is used to protect the reactor, reduce the scratches it receives underground, and improve its use effect.

[0026] The heat conducting device 2 includes a No. 1 aluminum alloy bracket 20 and a No. 2 aluminum alloy bracket 21.
