Description
Technical field
the present invention relates to the band blower fan oil-filled transformer in a kind of box-type substation.
Background technology
box-type substation is the complete power distribution equipment of compact combined by high-tension apparatus, power transformer, low voltage equipment and auxiliary equipment, because it has compact conformation, the advantage such as reliable, easy to maintenance and be widely used in the use that the places such as urban public distribution, skyscraper, residential quarters, industrial and mining enterprises and construction site receive and distribute electric energy.
conventional box-type substation, shown in accompanying drawing 1, oil-filled transformer normally carries out nature cooling in casing, and the heat on transformer generally needs to be dispersed in casing to be distributed by casing again.In order to ensure the useful life of transformer in box type transformer station, when transformer runs, its temperature needs to control below certain temperature, therefore requires in casing to control at lower temperatures, under such casing entirety is in a lower temperature, its natural heat dissipation amount is less, dispels the heat slower.Casing is generally provided with temperature control ventilation unit; when the temperature of transformer reaches certain value; temperature control ventilation unit is started working; the inside and outside wall of casing communicates and realizes ventilation and heat, and because heat radiation is comparatively slow, temperature control ventilation unit keeps operating state substantially; the inside and outside wall of casing keeps communicating; like this under the operational environments such as some humidity, salt fogs, box house equipment usually can be subject to the impact of external environment condition and be damaged, and have impact on the overall serviceability of transformer station.
Summary of the invention
the object of this invention is to provide the band blower fan oil-filled transformer of a kind of natural heat dissipation faster in box-type substation.
for achieving the above object, the technical solution used in the present invention is:
band blower fan oil-filled transformer in a kind of box-type substation, described box-type substation comprises casing, the oil-filled transformer be fixedly installed in described casing, described oil-filled transformer has multiple fin, described casing is also fixedly installed temperature control ventilation unit, during described temperature control ventilation unit work, the inside and outside of described casing is connected, described oil-filled transformer also comprises the multiple cooling blowers being fixedly installed on and described casing being positioned at bottom described multiple fin, and the air outlet of described multiple cooling blower aims at described multiple fin.
preferably, described cooling blower adopts Temperature Control Type cooling blower.
due to the utilization of technique scheme, the present invention compared with prior art has following advantages: be fixedly installed multiple cooling blower by the bottom being positioned at multiple fin on casing, and make the multiple fin on the air outlet of multiple cooling blower aligning oil-filled transformer, under the effect of cooling blower, heat on oil-filled transformer is distributed in casing rapidly by fin, bulk temperature in casing rises, temperature difference between casing inside and outside wall reduces fast, the natural heat dissipation of casing is accelerated, the radiating rate of oil-filled transformer is also accelerated, like this, temperature control ventilation unit does not work substantially, casing can keep a state sealed for a long time and not communicate with the external world, moist at some like this, under the operational environments such as salt fog, the equipment of box house would not be subject to the impact of external environment condition and be damaged, improve the overall serviceability of this box-type substation.
Accompanying drawing explanation
accompanying drawing 1 is conventional box-type transformer station and the structural representation of oil-filled transformer;
accompanying drawing 2 is the structural representation of box-type transformer station of the present invention and band blower fan oil-filled transformer.
Embodiment
below in conjunction with accompanying drawing, technical scheme of the present invention is further elaborated.
shown in Figure 2, band blower fan oil-filled transformer in a kind of box-type substation, this box-type substation comprises casing 1, the oil-filled transformer 2 be fixedly installed in casing 1, oil-filled transformer 2 has multiple fin, dispel the heat to prevent oil-filled transformer 2 and cause temperature to rise too high not in time and affect the useful life of transformer, casing 1 is also fixedly installed temperature control ventilation unit (not shown), temperature control ventilation unit is started working when the temperature of oil-filled transformer 2 reaches set point, and during its work, the inside and outside of casing 1 is connected.Oil-filled transformer 2 also comprises the multiple cooling blowers 3 being fixedly installed on and casing 1 being positioned at bottom multiple fin, the air outlet of multiple cooling blower 3 aims at multiple fin, during the work of this box-type substation, multiple cooling blower 3 works simultaneously like this, multiple cooling blower 3 work makes the heat on multiple fin be distributed in casing 1 rapidly, temperature in casing 1 is raised, casing 1 reduces fast with the temperature difference of oil-filled transformer 2, bulk temperature in casing 1 rises, temperature difference between such casing 1 inside and outside wall increases, the natural heat dissipation of casing 1 is accelerated, the radiating rate of oil-filled transformer 2 is accelerated.Like this, temperature on oil-filled transformer 2 does not generally reach the set point of temperature control ventilation unit, temperature control ventilation unit does not work substantially, casing 1 can keep a state sealed for a long time and not communicate with the external world, like this under the operational environments such as some humidity, salt fogs, the equipment of casing 1 inside would not be subject to the impact of external environment condition and be damaged, and improves the overall serviceability of this box-type substation.
when implementing, cooling blower 3 can adopt Temperature Control Type cooling blower, starts working, certainly when the temperature of oil-filled transformer 2 reaches certain value, this set point lower than the set point of temperature control ventilation unit, thus should prevent from the startup of temperature control ventilation unit and causes inside and outside casing 1 being connected.When some environments for use are comparatively severe, in order to the impact preventing the equipment of casing 1 inside to be subject to environment, the positive closing of temperature control ventilation unit can be made or this temperature control ventilation unit is not installed to ensure the integrally closed of casing 1.
Claims (2)
1. the band blower fan oil-filled transformer in a box-type substation, described box-type substation comprises casing, be fixedly installed on the oil-filled transformer in described casing, described oil-filled transformer has multiple fin, described casing is also fixedly installed temperature control ventilation unit, during described temperature control ventilation unit work, the inside and outside of described casing is connected, it is characterized in that: described oil-filled transformer also comprises the multiple cooling blowers being fixedly installed on and described casing being positioned at bottom described multiple fin, the air outlet of described multiple cooling blower aims at described multiple fin.
2. the band blower fan oil-filled transformer in a kind of box-type substation according to claim 1, is characterized in that: described cooling blower adopts Temperature Control Type cooling blower.
