Description

A reactor housing protection device

Technical Field

The utility model belongs to the technical field of reactors, and in particular relates to a reactor housing protection device.

Background Art

Reactors, also called inductors, are widely used in circuits. Because of the electromagnetic induction effect in circuits, there is a certain inductance, which can prevent current changes. When a conductor is energized, it will generate a magnetic field in a certain space it occupies, so all conductors that can carry current have inductance in a general sense.

According to patent No. CN202320330261.4, an intelligent capacitor reactor group protection device includes an outer shell, an inner shell is arranged inside the outer shell, the inner bottom wall of the outer shell and the lower surface of the inner shell are connected by multiple groups of shock-absorbing components, each group of shock-absorbing components includes a sleeve fixed to the inner bottom wall of the outer shell, a sleeve slidingly connected to the inner wall of the sleeve, and a spring arranged between the outer shell and the inner shell, one end of the spring is fixed to the inner bottom wall of the outer shell, and the other end of the spring is fixed to the lower surface of the inner shell, and the inner wall of the outer shell and the side wall of the inner shell are connected by multiple groups of support components.

The above scheme still has certain technical defects in actual use. Since only a spring is used as a buffer and shock absorber between the outer shell and the inner shell, and the sleeve and the casing only play a guiding role, the vibration caused by the collision or the operation of the internal components will cause the spring to repeatedly reset up and down, and the buffer and shock absorption effect is not ideal. Moreover, the heat dissipation port is connected to the gap between the outer shell and the inner shell, which makes it easy for external dust to enter the gap. When a lot of dust accumulates inside the slide groove, it will seriously affect the smoothness of the slider, resulting in jamming when vibration occurs, reducing the protective effect of shock absorption and buffering. For this reason, we propose a reactor housing protection device.

1.

Since the air cannot be discharged or inhaled quickly, a damping effect is generated. In conjunction with the buffer spring, the purpose of reducing the amplitude is achieved, thereby achieving a better buffering and shock absorption effect and improving protection.

2. By setting a corrugated sleeve on the periphery of the heat dissipation port and the cooling fin, and cooperating with a dustproof net, the inside of the buffer tank can be dust-proof. In combination with a heat conduction plate, cooling fin and heat dissipation fins, heat is transferred to the corrugated sleeve by heat transfer, and then a cooling fan is used for ventilation and heat dissipation. While ensuring the heat dissipation efficiency, external dust is prevented from entering the inside of the buffer tank.

Specifically, the inner wall surfaces of both sides of the buffer groove 3 are provided with slide grooves 4, and sliders 5 are fixedly provided on the inner wall of the outer shell 1 of the slide groove 4 and on both sides of the outer side of the inner shell 2.
