Description
Technical field
The utility model relates to a kind of main transformer sheet that reduces and to fall apart the technical scheme of ventilation of room temperature, is specially a kind of indoor main transformer sheet and falls apart the textural association that room bottom air inlet arranges.
Background technology
In current transformer station, main transformer room and the sheet main draft type in room of faling apart is with natural air inlet, the mode of mechanical exhaust is carried out, but the limited area of air inlet on the one hand due to main transformer gate in indoor station leaving, on the other hand owing to needing to add screen pack on air feed shutter, effective incoming air area of main transformer room is reduced further, makes the air current composition in room unreasonable.
Existing problems 1, because the air current composition of transformer chamber is unreasonable, make the Temperature Distribution in room unreasonable, thus the temperature that result in room is too high, when being unfavorable for that main transformer runs, the heat of generation is delivered to indoor, and then outside discharge chamber.
Existing problems 2, transformer chamber's temperature are too high, make the over proof limit value of main transformer operating temperature.Transformer temperature has a great impact its operation, most importantly affects the dielectric strength of TRANSFORMER INSULATING MATERIAL.The insulating material used in transformer, for a long time under the effect of temperature, can reduce original insulation property gradually, shortens service life.In addition, do not damage even if transformer insulated, but temperature is higher, the dielectric strength of insulating material is poorer, is easy to be broken down by high-voltage cause fault.
Existing problems 3, because main transformer temperature is higher, makes blower fan long-play at relatively high temperatures, slow down the service life of blower fan, thus add workload and the expense of later maintenance.
Utility model content
Of the present utility model
goal of the inventionjust be to provide a kind of indoor main transformer sheet to fall apart textural association that room bottom air inlet arranges, avoids that main transformer room temperature is too high to be impacted operation, and it has economy, safety, easy implementation, can be widely used in indoor substation.
Of the present utility model
technical schemefor fall apart textural association that room bottom air inlet arranges of: a kind of indoor main transformer sheet of the utility model comprises and is arranged on sheet and falls apart the air inlet of the band air feed shutter arranged below gate, room, be arranged on sheet to fall apart the exhaust blower of indoor top, it is characterized in that: an air-intake shaft is set out of doors, air-intake shaft be positioned at the cable interlayer that sheet falls apart below room and be connected, air-intake shaft is provided with the blower fan of air intake, and faling apart at sheet offers the air inlet of band fire resisting damper between room and cable interlayer;
Described air-intake shaft air inlet to be arranged on above air inlet fan and to be equipped with air feed shutter.
Of the present utility model
beneficial effectfor:
This patent is by building an air-intake shaft out of doors, be connected with cable interlayer, and on air-intake shaft, install a Fans additional as air inlet fan, outdoor air enters into cable interlayer by air-intake shaft, and air themperature is reduced, cold air falls apart via sheet, and to enter into sheet loose indoor for the air inlet opened below room, and the air inlet driveed in ground will have fire resisting damper, to reach fireproof requirement.Portion of air enters into indoor by the air feed shutter offered below gate on the other hand, and two strands of air-flows form comparatively reasonably air current composition scheme and reach good aeration-cooling effect.
The ventilating system that the utility model adopts a set of natural air inlet, mechanical air intake+mechanical dust removal falls apart room as main transformer sheet, effectively can not only improve the irrational problem of air current composition in original ventilating system, the cold air that in underground cable interlayer, temperature is lower can be utilized simultaneously, under the condition meeting air-conditioning requirement, reduce blower ventilation amount to reach energy efficient, ensure the object that main transformer normally runs.
Technological progress of the present utility model is: (1) has taken into full account that main transformer sheet falls apart indoor air current composition situation; (2) make use of the air that in underground cable interlayer, temperature is lower, suitably reduce ventilation quantity, energy-conservation energy consumption; (3) easy construction, safe and reliable, and meet fire prevention related request; (4) natural air inlet+mechanical air intake, the energy efficient when meeting ventilation quantity; (5)
The indoor main transformer sheet of the utility model room air supply at the bottom placement technique that falls apart mainly make use of underground cable interlayer and is positioned at underground constant zone of subsurface temperature, the feature that temperature is lower, air temperature after cable interlayer is reduced, thus reduces the object that inlet temperature reaches raising drafting efficiency.This technology has taken into full account the impact of air current composition on ventilation effect on the other hand, improves ventilation effect, make indoor temperature control in a rational scope when ventilation quantity is certain, ensure that the normal safe of equipment runs, remarkable in economical benefits.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model one embodiment.
Embodiment
A kind of indoor main transformer sheet of the utility model falls apart the textural association that room bottom air inlet is arranged as shown in Figure 1, it comprises and is arranged on sheet and falls apart the air inlet 1 of the band air feed shutter 3 arranged below gate, room 4, be arranged on sheet to fall apart the exhaust blower 6 of indoor top, an air-intake shaft 2 is set out of doors, air-intake shaft 2 be positioned at the cable interlayer 5 that sheet falls apart below room 4 and be connected, air-intake shaft 2 is provided with the air inlet fan 7 of air intake, and faling apart at sheet offers the air inlet 28 of band fire resisting damper between room 4 and cable interlayer 5; The air inlet 39 of described air-intake shaft 2 to be arranged on above air inlet fan 7 and to be equipped with air feed shutter 3.
The utility model is by building an air-intake shaft out of doors, be connected with cable interlayer, and on air-intake shaft, install a Fans additional as air inlet fan, outdoor air enters into cable interlayer by air-intake shaft, and air themperature is reduced, cold air falls apart via sheet, and to enter into sheet loose indoor for the air inlet opened below room, and the air inlet driveed in ground will have fire resisting damper, to reach fireproof requirement.Portion of air enters into indoor by the air feed shutter offered below gate on the other hand, and two strands of air-flows form comparatively reasonably air current composition scheme and reach good aeration-cooling effect.
Specific implementation process is: first air intake enters into air-intake shaft by air feed shutter, then be blown in cable interlayer via the air inlet fan installed in air-intake shaft, air intake is lowered the temperature in cable interlayer, then enters into sheet via the sheet air feed shutter (band fire resisting damper) fallen apart bottom room and to fall apart room; On the other hand a part of air intake be by gate bottom air feed shutter directly to enter into sheet loose indoor, then air intake after carrying out heat exchange with heat dissipation equipment within doors through by being installed in outside the roof extract unit discharge chamber on roof.
