Description

Technical Field

[0001] The utility model relates to the technical field of transformer substation shells, in particular to an anti-condensation preassembled transformer substation shell. Background Art

[0002] Prefabricated substation, also known as box-type substation or prefabricated substation, is a kind of factory-prefabricated indoor and outdoor compact distribution equipment that is arranged in a certain wiring scheme with high-voltage switchgear, distribution transformer and low-voltage distribution device. With the rapid development of the power industry, there are more and more types of equipment, and the size of various metal box-type electrical equipment is also developing towards compactness. Prefabricated substation is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It replaces the original civil power distribution room and distribution station and becomes a new type of complete set of power distribution equipment. However, due to the different environments of substations, the requirements for their reliability are also increased. Metal box-type equipment will cause condensation and dirt in the box due to temperature difference, sealing and other reasons. Long-term condensation in the box will cause rust and damage to the cabinet; condensation on the equipment or condensation dripping on the equipment may cause creepage flashover; condensation and dust on the equipment form a conductive channel that will destroy the electrical insulation, which will cause varying degrees of damage to the equipment in the box, affecting the reliable transmission of electricity. Utility Model Content

[0003] Aiming at the problem that condensation is easily generated due to the influence of environment on the internal rate of return of prefabricated substation in the prior art, the utility model provides a condensation-proof prefabricated substation casing to solve the above problem.

[0004] The technical solution of the utility model is as follows:

[0005] A condensation-proof prefabricated substation shell, comprising a wall and a top cover; a lower deck is provided under the top cover; the lower deck contains at least one inclined surface; the edge of the lower deck extends out of the wall; the surface of the lower deck is in a folded shape, and a water guide groove is formed at the fold; the water guide groove is in the same direction as the inclined surface of the lower deck; a heat dissipation window is provided at one end of the water guide groove outside the wall; a humidity regulating sheet is provided on the inner surface of the wall for absorbing or releasing moisture to regulate the humidity inside the substation; a plurality of humidity regulating sheets are provided.

[0006] Furthermore, the lower deck board has two inclined surfaces, presenting an arrangement of being higher in the middle and lower on both sides.

[0007] Furthermore, the top cover has four symmetrically arranged hooks for hoisting the top cover from above the wall when installing the prefabricated substation.

[0008] Furthermore, the opening of the heat dissipation window faces downwards, which can ensure that the generated condensation is removed and prevent moisture from entering the substation when it rains or the air is humid.

[0009] Furthermore, the heat dissipation window is provided with a wire mesh to prevent birds and flying insects from entering the substation.

[0010] Furthermore, the humidity-regulating sheet is arranged near the lower part of the wall. Humid air mainly comes from the civil foundation below the substation, and the dehumidification effect will be better if the humidity-regulating sheet is arranged near the lower part.

[0011] The beneficial effects of the utility model are:

[0012] 1. The utility model sets the lower deck under the substation top cover into an inclined plane, and forms a water guide groove in the inclined direction of the lower deck, which can ensure that the water droplets condensed on the top cover are discharged from the heat dissipation window along the M-shaped groove water guide groove from high to low under the action of gravity and surface tension, avoiding direct dripping on the electrical equipment below.

[0013] 2. The utility model installs a humidity control sheet on the wall to adjust the humidity inside the substation. The humidity control sheet is made of a high-performance macromolecular polymer, and its component is acrylic rubber resin, a type of polymer with high water absorption. Due to the action of the hydrophilic groups in the polymer, water molecules in the air are easily absorbed into the body. After the water molecules enter the body, the ionized groups on the chain are ionized in the water, and the electrostatic repulsion between the same ions causes the polymer chain to stretch and swell, further absorbing water into the rubber resin (the surface phenomenon is the expansion of the humidity control sheet). On the contrary, when the humidity in the environment decreases, the water molecules in the molecular chain will be discharged back into the air because the osmotic pressure in the molecular chain is weakened. Under the combined action of these two, the effect of anti-condensation is achieved. BRIEF DESCRIPTION OF THE DRAWINGS
