Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 3.

The utility model discloses a preassembled transformer substation, which comprises a box body 1, wherein one side of the box body 1 is provided with a switch door 10, the upper part of the box body 1 is provided with a box top 2, the other three sides of the box body 1 are provided with shells 3 which are arranged in a clearance way with the box body 1, a water storage cavity 30 is formed between the shells 3 and the box body 1, one end of each shell 3 close to the box top 2 is bent outwards and extends out of the box top 2 area to form a guide plate 31, a vent groove 11 is arranged in a box plate above the box body 1, an air outlet pipe 12 communicated with the vent groove 11 is arranged above the box body 1, one side of the air outlet pipe 12 is provided with an air pump 13 matched with the air outlet pipe 12, the inner wall of the box body 1 is provided with air inlet holes 14 communicated with the vent groove 11 in an arrangement way, the two air inlet holes 14 close to the two ends of the vent groove 11 are both, one end of the iron wire 40 is fixed on the inner wall of the box body 1, and the end part of the air inlet pipe 4 is provided with a horn-shaped air inlet cover 41. A semicircular dust cover 5 arranged in a clearance manner is arranged at the opening of the air outlet pipe 12, and a fixing rod 50 fixedly connected with the box top 2 is arranged on the dust cover 5. One side of the box top 2 close to the opening and closing door 10 of the box body 1 is provided with a water guide plate 20, and two ends of the water guide plate 20 respectively extend towards two sides of the box top 2. And a plurality of overflow holes 32 are formed in one end of the outer shell 3 close to the top 2 of the tank. The number of the overflow holes 32 is at least six, and the overflow holes 32 are obliquely arranged from one end close to the tank top 2 to the direction of the tank bottom. And waterproof layers 15 are arranged on the outer walls of the box body 1 corresponding to the shell 3. When radiating, the two different radiating modes are combined.

The inner wall of the water storage cavity 30 is provided with an anti-corrosion layer, and preferably, the anti-corrosion layer is modified asphalt. In order to prolong the service life of the water storage cavity 30, after the pre-installed transformer substation is installed, partial alkaline liquid can be injected into the water storage cavity 30 manually, so that the rainwater can be neutralized when falling, the corrosion of the acidic rainwater to the inner wall of the water storage cavity 30 is avoided, and after a certain time, such as half a year or a year, the water storage cavity 30 is cleaned by clean water. A drain valve 6 is arranged at a position, close to the lower part, of the water storage cavity 30, and the drain valve 6 is opened and closed during cleaning.

As shown in fig. 1, three sides of the box body 1 are covered by the casing 3, and the casing 3 is not provided on the side provided with the opening and closing door 10, so that the extracted gas is supplied from the door gap of the opening and closing door 10. The water guide plate 20 is arranged right above the switch door 10, and the water guide plate 20 plays a role of an eave, so that rainwater is difficult to enter a door gap of the switch door 10.

In actual operation, this transformer substation has extremely strong heat-sinking capability, in rainy, can be by the effectual water storage chamber 30 of collecting formation between shell 3 and the box 1 through the rainwater that the water conservancy diversion got off on roof 2 in, the water in the water storage chamber 30 alright carry out effectual heat dissipation for box 1 this moment, utilize the change of weather to make and to carry out retaining throughout in the water storage chamber 30, do not worry that the evaporation of moisture leads to the heat-sinking capability inefficacy, unusual practicality. Then people alright open air extractor 13 and dispel the heat to box 1 inside, because outlet duct 12 is being linked together the setting with air channel 11, so when air extractor 13 bleeds, the inlet port 14 of arranging the setting on the box 1 inner wall can bring a large amount of steam into air channel 11, and the steam that reachs in the air channel 11 just can give off to box 1 outside from outlet duct 12 to reach quick radiating effect. Simultaneously, people can also independently radiate the components with larger heat productivity through the air inlet pipe 4, and the air inlet pipe 4 is grabbed when the heat dissipation device is used, so that the air inlet cover 41 of the air inlet pipe 4 can be aligned to the heating components, at the moment, the air inlet pipe 4 can be fixed and kept still through the iron wire 40, the air inlet cover 41 can be used for rapidly radiating the heating components independently, the heat dissipation capacity of the transformer substation is greatly improved, and the components are effectively protected. Be equipped with a semicircular dust cover 5 that is the clearance setting through the opening part at outlet duct 12, be equipped with on dust cover 5 with roof 2 fixed connection's dead lever 50 for the opening part of outlet duct 12 is difficult to fall into the dust, prevents that the dust can get into in the box 1, leads to components and parts impaired. Through be equipped with water guide plate 20 at roof 2 near one side of box 1 switch door 10, the both ends of water guide plate 20 extend towards the both sides of roof 2 respectively for in rainy, the rainwater can be all by the water conservancy diversion to the retaining chamber 30 through water guide plate 20, increased the ability of retaining. Through being equipped with a plurality of spillway hole 32 at the shell 3 one end that is close to roof 2 for water can flow out through spillway hole 32 when continuing full, unusual practicality. The number of the overflow holes 32 is at least six, and the overflow holes 32 are obliquely arranged from one end close to the tank top 2 to the bottom of the tank, so that the overflow holes 32 can rapidly pour away redundant water, and the overflow holes 32 are obliquely arranged so that water flowing down from the guide plate 31 cannot flow out along the overflow holes 32 when passing through the overflow holes 32. All be equipped with waterproof layer 15 on the outer wall through corresponding shell 3 at box 1 for box 1's waterproof ability can great promotion, also guaranteed box 1's leakproofness in the refrigerated, improved holistic security performance. The utility model discloses a transformer substation heat-sinking capability is strong, the effectual inside temperature of transformer substation that has reduced, great promotion the life of components and parts.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
