Description
Technical field
The present invention relates to field of power, specifically is a kind of preassembled transformer station.
Background technology
Preassembled transformer station is widely used in the open air in the places such as residential quarters, industrial and mining enterprises, hotel, hospital, airport, railway as the change power distribution equipment of looped network type or terminal type.Preassembled transformer station comprises housing and earthing device, be provided with high voltage switchgear, distribution transformer and low-voltage distribution equipment in the housing, suspention is fixed with air-breathing ventilating fan in the housing above distribution transformer, base plate at housing is provided with air inlet, air-breathing ventilating fan so that air enter from air entry, then discharged by air-breathing ventilating fan, and the heat that distribution transformer work produces dissipates in the process of gas circulation convection current.Earthing device comprises common ground body and the ground path that is embedded in ground, distribution transformer and the first copper bar are fixed, the first copper bar is connected with metal base plate through double-screw bolt, metal base plate is positioned at housing, metal base plate is electrically connected with housing the second copper bar outward by the screw that runs through housing sidewall, the second copper bar is connected with housing common ground body outward, the first above-mentioned copper bar, double-screw bolt, metal base plate, screw, the second copper bar connect successively, consisted of ground path, the electric charge on distribution transformer surface finally is transmitted to the common ground body through ground path and is grounded.
There is following defective in the preassembled transformer station of prior art: at first, some ultrahigh-temperatures area such as the desert in, the radiating effect of the preassembled transformer station of prior art is still undesirable, the heat that distribution transformer produces in the housing still can't in time shed, temperature is still higher in the housing, and distribution transformer continues under hot environment that its useful life is shortened in the operation meeting, failure rate is high; Secondly, the door of this preassembled transformer station is made by the thick sheet metal of general 2mm, the steel-sheet heat-proof quality is poor, under the high temperature outdoor environment, can cause equally the electric elements excess Temperature in the housing, affect job stability, even there is a potential safety hazard, and the steel-sheet door-plate is the externally lower distortion of bump easily, to the electric elements protection underbraced of box house; Moreover, ground path is formed by connecting by a plurality of parts, connected node is more, if any one node loose contact such as double-screw bolt get loose, will cause not conducting of ground path, so that ground connection is malfunctioning even cause security incident, so require occasion high, that the serious forgiveness requirement is low at safety and stability, the preassembled transformer station of prior art can't satisfy safety requirements.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of and can strengthen the preassembled transformer station that radiating effect can be strengthened again effect of heat insulation.
Technical solution of the present invention is, a kind of preassembled transformer station is provided, it comprises housing, be hinged with the door that steel plate is made on the housing, distribution transformer is installed in the housing, and the case top suspention is equipped with the first air-breathing ventilating fan, and the first air-breathing ventilating fan is positioned at the top of distribution transformer, the sidewall of housing is penetrated with installing hole, is provided with the second air-breathing ventilating fan in each installing hole; The outer surface of door is fixed with imitative plank.
Adopt the preassembled transformer station of above structure compared with prior art, have the following advantages:
Because the sidewall of housing is penetrated with installing hole, be provided with the second air-breathing ventilating fan in each installing hole, like this, this preassembled transformer station namely enters from the air inlet of base plate except the circulative convection path that possesses prior art, outside the first air-breathing ventilating fan of case top is discharged, also increased new circulative convection path, after namely entering from the air inlet of base plate, discharge from the second air-breathing ventilating fan of sidewall, so strengthened radiating effect, so that the heat that distribution transformer produces in the housing can in time be discharged, temperature in the decrease housing, be particularly useful for the ultrahigh-temperature area as in the desert, prolonged useful life, reduced failure rate; Also because the outer surface of door is fixed with imitative plank, the imitative plank of increase can strengthen the integral heat-insulation property of door, so that the good heat-insulation effect of housing is particularly useful for the high temperature outdoor environment, avoids electric elements excess Temperature in the housing, has guaranteed job stability; Secondly, owing to increased the protection of imitative plank, so that door is not yielding after being impacted, crashproof effect is better, and is good to the electric elements protection support effect of box house; Moreover imitative plank can not consume real timber, meets the theory of energy-conserving and environment-protective.
As improvement, installing hole is two, two installing holes are set on the sidewall, confirm in actual use, can effectively strengthen convection effects, reduce temperature in the housing, and cost control is reasonable, do not increase considerably cost, moreover, find in actual the use, increase by two installing holes that constantly outwards dispel the heat, can not reduce the thermal insulation of housing integral body.
As improving, imitative plank is polylith again, and polylith is imitated plank head and the tail and neat and vertical, has the slit between per two adjacent imitative planks; Also be provided with the imitative plank of level on the door, the vertical imitative plank of the imitative plank of level and the polylith on this is fixed, and like this, uses confirmation through reality, imitates being intervally arranged of plank, and its effect of heat insulation is still very desirable, and can save again the material of imitative plank, reduces cost; And level and vertical imitative plank have formed the overall structure of paliform, and its crashproof effect is better.
As also improving, it comprises common ground body and the copper bar that also is positioned at outside the housing, be fixed with the base plate that is above the ground level in the housing, distribution transformer is fixed on the base plate, copper bar passes base plate and sidewall, copper bar one end is connected with distribution transformer, the other end of copper bar is connected with the common ground body, like this, this preassembled transformer station directly adopts one whole copper bar that passes base plate and sidewall as ground path, compared to existing technology, connected node obviously reduces, so reduced the hidden danger of loose contact, decrease the malfunctioning probability of ground connection, greatly degree is avoided the generation of security incident, and electric conductivity obviously strengthens, and it is high to be particularly useful for the safety and stability requirement, serious forgiveness requires low occasion.
