[0026] The coil 3 is provided with an explosion-proof enclosure 6. The inner cavity of the explosion-proof enclosure 6 is bolted to the top of the L-shaped piece 4. The front cover 7 of the enclosure is slidably connected to one side of the explosion-proof enclosure 6. The wiring terminal 5 passes through the front cover 7 and extends to the outside of the front cover 7.

[0027] In a specific embodiment, as shown in the appendix Figure 3 As shown, the terminal block 5 is bolted to a connecting plate 8. A dust cover 9 is fixedly connected to one side of the connecting plate 8. An insulating cloth 10 is provided on one side of the dust cover 9. The insulating cloth 10 and the dust cover 9 are fixedly connected by a corner bracket 11. The outer wall of the insulating cloth 10 is provided with an electrical port 12 to prevent dust from contacting the electrical contact surface.

[0028] Specifically, in this structure, the operator inserts the wire from the power port 12 into the dust cover 9 and fixes the wire to the wiring segment 5 inside the dust cover 9.

[0029] In a specific embodiment, as shown in the appendix Figure 2 As shown, multiple fans 13 are installed on one side of the explosion-proof enclosure 6. Gaskets 14 are fixedly connected to the outer wall of the fans 13 and bolted to the explosion-proof enclosure 6. An air outlet 15 is opened on the other side of the explosion-proof enclosure 6. A filter screen 16 is fixedly connected to the inner wall of the air outlet 15 to facilitate cooling of the reactor.

[0030] Specifically, in this structure, the operator starts the fan 13, which carries away the heat generated by the current passing through the coil 3 from the air outlet 15.

[0031] In a specific embodiment, as shown in the appendix Figure 2As shown, a temperature display screen 17 is installed between the two terminals 5.

[0032] Specifically, in this structure, the operator decides whether to turn on the fan 13 to cool down by observing the temperature displayed on the temperature display screen 17.

[0033] In a specific embodiment, as shown in the appendix Figure 4 As shown, a groove 18 is fixedly connected to one side of the front cover 7 of the enclosure, and a groove 19 is provided on the outer wall of the groove.

[0038] Specifically, in this structure, the explosion-proof enclosure 6 and the front cover 7 are connected by bolts.

[0039] The working principle of this utility model is as follows: When the explosion-proof reactor is in operation, the operator first slides the front cover 7 into the explosion-proof enclosure 6, using the sealing ring 20 to prevent dust from entering the interior of the enclosure 6. Then, the front cover 7 and the enclosure 6 are fixed together with bolts. The connecting wire is pulled to the front of the front cover 7 and inserted through the power port 12 into the dust cover 9, connecting it to the terminal 5. The fan 13 is then turned on to cool the coil 3. When dust accumulates inside the fan 13, it is removed from the gasket 14 using bolts for replacement or cleaning. This device solves the problem of dust, dirt, and other impurities accumulating on the electrical contact surfaces of the explosion-proof reactor during long-term operation, which may lead to poor heat dissipation and poor electrical contact. Furthermore, the explosion-proof enclosure 6 of this reactor is made of engineering plastic, which has high strength and rigidity, as well as heat resistance, corrosion resistance, and electrical insulation.
