Description

A kind of aeration structure of buried preassembled transformer station

Technical field

The utility model belongs to preassembled transformer station technical field, and in particular to a kind of ventilation of buried preassembled transformer station Structure.

Background technique

Preassembled transformer station realizes electrical connection by cable or bus, and all high-low voltage power distribution devices and transformer are equal For conventional approved product.Preassembled transformer station is called " box change " or " prepackage type electric substation ", often can be in park, house Area, industrial area are seen.Preassembled transformer station volume is larger, needs to occupy certain space place.In land used anxiety or environment Preassembled transformer station is bought in underground by severe area, forms buried preassembled transformer station, can effectively save ground sky Between, also need not to substation casing carry out design for aesthetic, substation by destroy a possibility that it is small, can be improved Electrical Safety. But after substation is embedded to underground, the ventilation effect of box house will influence whether temperature, the humidity even oxygen of box house Gas concentration etc..The above problem is able to solve using exhaust blower etc., but needs additional buying installation cost and maintenance cost.

Summary of the invention

In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of buried preassembled transformer station Aeration structure, the substation include the transformer station box and dew maintenance cabinet on the ground for being embedded in subsurface, maintenance Cabinet has the chamber door passed in and out for service personnel, and maintenance cabinet is connected to transformer station box by entrance, and inlet, which is fixed with, to be protruded into Ladder inside to transformer station box, ventilation duct is further fixed on the transformer station box, and ventilation duct and maintenance cabinet distinguish position In transformer station box it is diagonal on, one end of ventilation duct is basseted, and the other end overhauls cabinet close to transformer station box bottom There is ventilating blind on side wall.

One end that ventilation duct bassets is equipped with the lid that keeps off the rain, and the lid that keeps off the rain is fixed by the bracket the nozzle in ventilation duct.

Ventilation duct, which goes out, is equipped with filter screen at the nozzle of ground one end, filter screen includes ring set and is fixed in ring set Screen cloth, ring set are threadedly coupled with ventilation duct.

Transformer station box bottom is equipped with around the one week escape pipe in transformer station box bottom, and escape pipe is connected to ventilation duct, outlet Several stomatas are evenly distributed on pipe, stomata is upward.

The bottom of escape pipe is equipped with drainpipe, and drainpipe is connected with water receiving tank, and water receiving tank is threadedly coupled with drainpipe.

Several sponges are placed on filter screen.

The lid that keeps off the rain is made of transparent plastic.

The working principle of the utility model is: substation is at work, the heat that electronic component distributes is by the intracorporal sky of case Gas heating, hot-air rise from inlet through maintenance cabinet discharge, and the bottom of box forms negative pressure, so that ozone is from ventilation Cabinet, transformer station box and extraneous realization cross-ventilation circulation are constantly supplemented at pipe.

The beneficial effects of the utility model are: the aeration structure of the buried preassembled transformer station of the utility model, utilizes change The heat that power station itself generates is realized that the convection current with outside air is taken a breath, can effectively be adjusted in buried preassembled transformer station Temperature, humidity and the air quality in portion, while having saved cost.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the utility model schematic cross-section；

Fig. 3 is the enlarged diagram to keep off the rain at lid.

Specific embodiment

Now in conjunction with attached drawing, the utility model is described in further detail.

As shown in Figure 1-3, a kind of aeration structure of buried preassembled transformer station, the substation includes to be embedded in subsurface Transformer station box 1 and dew maintenance cabinet 2 on the ground, maintenance cabinet 2 has chamber door pass in and out for service personnel, overhauls Cabinet 2 is connected to transformer station box 1 by entrance, and inlet is fixed with the ladder extending into inside transformer station box 2, the power transformation Stand and be further fixed on ventilation duct 3 on cabinet 2, ventilation duct 3 and maintenance cabinet 2 be located at transformer station box 1 it is diagonal on, ventilation duct 3 one end is basseted, and for the other end close to 1 bottom of transformer station box, overhauling has ventilating blind 4 on the side wall of cabinet 2.Power transformation Stand work when the heat that itself generates the air inside substation is heated, the principle risen using hot-air, hot-air is from entering The shutter that mouth is overhauled cabinet is discharged, and hot-air takes away the heat and steam of box house.Air pressure inside and outside substation generates Pressure difference, fresh air enter substation bottom through ventilation duct, realize cooling, dehumidifying inside substation.

One end that ventilation duct 3 bassets is equipped with the lid 5 that keeps off the rain, and the lid 5 that keeps off the rain is hemispherical, and the lid 5 that keeps off the rain is fixed by bracket 8 In the nozzle of ventilation duct 3.

Ventilation duct 3, which goes out, is equipped with filter screen at the nozzle of ground one end, filter screen includes ring set 6 and is fixed in ring set Screen cloth 7, ring set 6 is threadedly coupled with ventilation duct 3.Filter screen prevents solid matter from entering blocking ventilation duct 3.

1 bottom of transformer station box is equipped with around the 1 one week escape pipe in bottom 9 of transformer station box, and escape pipe 9 is connected to ventilation duct 3, Several stomatas 10 are evenly distributed on escape pipe 9, stomata 10 is upward.Air is from 1 bottom surrounding of transformer station box even into guarantor There is air-flow process in card transformer station box 1, prevents the phenomenon of dead space, part humidity.

The bottom of escape pipe 9 is equipped with drainpipe 11, and drainpipe 11 is connected with water receiving tank 12, water receiving tank 12 and 11 spiral shell of drainpipe Line connection.The enough discharges from drainpipe 11 of water energy when ventilation duct 3 is surprisingly intake in ventilation duct 3.Service personnel's periodic cleaning connects Sink 12.

Several sponges 13 are placed on filter screen, the lid 5 that keeps off the rain is made of transparent plastic.Sponge 13 is used to absorb the water of air Vapour prevents steam from entering inside transformer station box 1 as far as possible in misty rain day.When becoming a fine day, sunlight keeps off the rain through transparent Lid 5 can be with rapid airing sponge 13.

The preferred embodiments of the present invention have been described in detail above, it should be understood that the ordinary skill people of this field Member according to the present utility model can conceive without creative work makes many modifications and variations, therefore, all this technology necks Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain Available technical solution is tested, it all should be within the scope of protection determined by the claims.
