Fig. 2 is a schematic structural diagram of a cover plate in a waterproof mechanism of a dry-type transformer according to the present invention.
As shown in the figure: 1. the box body 2, a heat dissipation port 3, a cover plate 4, a heat dissipation channel 5, a water absorption net box 6, a box cover 7 and a flow guide rod.
Detailed Description
The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.
Examples, see fig. 1-2:
the utility model provides a waterproof mechanism of dry-type transformer, includes box 1 and two cover plates 3, and a plurality of thermovent 2 has been seted up to the side of box 1, should have the fan in the box 1, and the fan blows off the hot-air in the box 1 in by thermovent 2.
Two 3 fixed connection of cover plate form heat dissipation channel 4, cover plate 3 is U type structure, the flange has on the U type opening of a cover plate 3, the recess has on the U type opening of another cover plate 3, two U type openings of cover plate 3 are relative during the installation, the flange laminating is and through bolt fixed connection in the recess, thereby realize two connection of cover plate 3, and wherein lie in and should place the rubber seal strip between flange and the recess, in order to avoid the infiltration of rainwater, the integrated configuration of two cover plates 3 can be convenient for heat dissipation channel 4's the maintenance and the change of granule that absorbs water.
The heat dissipation channel 4 is fixedly arranged on the box body 1, the cover plates 3 are welded with U-shaped plates, after the two cover plates 3 are mutually connected, the two U-shaped plates form an annular plate which is fixed on the side surface of the box body 1 through bolts so as to communicate the upper port of the heat dissipation channel 4 with the heat dissipation port 2, wherein should place rubber seal between annular plate and the box 1, in order to avoid the infiltration of rainwater, heat dissipation channel 4 via the 2 slope downwardly extending of thermovent, the hot air that blows off in by thermovent 2 is by heat dissipation channel 4 downwardly directed and discharge from heat dissipation channel 4's lower port department, outside rainwater receives heat dissipation channel 4's separation then can't enter into in the box 1 by in thermovent 2, the one end fixed mounting who keeps away from box 1 on the cover plate 3 has guide rod 7, guide rod 7 is used for the water conservancy diversion of rainwater, the rainwater can be smooth and easy flow down on heat dissipation channel 4 when guaranteeing to rain.
A plurality of water absorption net boxes 5 are fixedly arranged in the cover plate 3, the water absorption net boxes 5 are provided with grid holes which are uniformly distributed so as to enable air to pass through, water absorption particles are filled in the water absorption net boxes 5, the diameters of the water absorption particles are larger than those of the grid holes in the water absorption net boxes 5, the water absorption particles are silica gel dry particles, when the air passes through the water absorption net boxes 5, moisture in the air can be absorbed into the silica gel dry particles, therefore, the external moisture is greatly reduced to enter the box body 1 along with the air from the heat dissipation port 2, when the hot air in the box body 1 passes through the water absorption net boxes 5, the silica gel dry particles can be dried, the silica gel dry particles can be reused, one end of the water absorption net boxes 5, which is far away from the cover plate 3, is provided with an opening, a box cover 6 is fixedly covered on the opening of the water absorption net boxes 5 through screws, and after the water absorption capacity of the silica gel dry particles, then the silica gel dry particles can be replaced by disassembling and assembling the box cover 6.
