Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

For conveniently understanding the utility model provides a relay protection device, the application scene of the relay protection device that this application embodiment provided is explained at first, and the relay protection device that this application embodiment provided is used for protecting the relay, the effectual protection device of relay disappearance among the prior art, therefore this application provides a relay protection device for solve above-mentioned problem. The following detailed description is made with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic structural diagram of a relay protection device according to an embodiment of the present invention, fig. 2 is a cross-sectional view of a protection box according to an embodiment of the present invention, and fig. 3 is a partial enlarged view of a position a in fig. 2 according to an embodiment of the present invention.

As shown in fig. 1, 2 and 3, the relay protection device includes a protection box 1, two horizontal partition plates 2 are disposed in the protection box 1, through holes are disposed on each partition plate 2, and the number of the through holes is multiple and is uniformly distributed on the partition plates 2. Any inner wall of the through hole is provided with a hemispherical damping body 3, a heat conductor 4 is arranged in a space enclosed between the damping bodies 3, and two ends of the heat conductor 4 are respectively exposed outside the through hole. Shock attenuation body 3 and heat conductor 4 are the heat conduction colloidal silica body, and heat conductor 4 is the little dysmorphism body in the middle of the big of both ends, and the space looks adaptation that encloses between heat conductor 4 and the shock attenuation body 3 simultaneously, and is concrete, in close contact with between the two, so not only has good shock attenuation effect, has good heat conductivility moreover, can also play the purpose of hindering dirt simultaneously.

With continued reference to fig. 1, 2 and 3, a heat absorbing plate 5 is connected to an end of the heat conductor 4 facing between the two partition plates 2, a heat dissipating plate 6 is connected to an end of the heat conductor 4 facing outside the two partition plates 2, and heat dissipating fins 7 are disposed on the heat dissipating plate 6. The heat absorbing plate 5 and the heat radiating plate 6 are both copper plates or aluminum plates, and the heat radiating fins 7 are copper plates or aluminum plates. In addition, the part of the side part of the protection box 1, which is positioned outside the two clapboards 2, is provided with a heat dissipation slot hole 8, the heat dissipation slot hole 8 is communicated with the inside and the outside of the protection box 1, and the heat dissipation slot hole 8 and the heat dissipation fins 7 are arranged in a staggered manner.
