Abstract
The invention relates to a method for improving heat dissipation rate of a main transformer room in an old substation. The substation comprises the main transformer room formed by a plurality of walls and a main transformer observation room sharing a side wall with the main transformer room. The method includes the steps: S1, arranging a partition hole on the wall between the main transformer room and the main transformer observation room; S2, mounting an exhaust fan in the partition hole; and S3, mounting an exhaust pipeline, wherein one end of the exhaust pipeline is connected with the exhaust fan while the other end of the exhaust pipeline penetrates through the main transformer observation room to extend out of the substation. In order to solve the problem of poor heat dissipation of main transformer rooms of old substations, the exhaust fan and the exhaust pipeline are mounted on the side wall of the main transformer room to form an air circulation system to draught the main transformer room, air inside and outside the main transformer room is forcedly exchanged to dissipate heat accumulated in the main transformer room, and thereby air circulation in the main transformer room is quickened, and heat dissipation effect of the main transformer room can be greatly improved.
Description
Technical field
The present invention relates to a kind of method that improves transformer chamber's rate of heat dissipation in the old transformer station.
Background technology
Be accompanied by rapid development of economy, electricity need load totally presents the trend that increases substantially, especially 1.2 times of the load annual load especially during meeting the kurtosis summer.But, corresponding substation equipment can't catch up with so swift and violent step fully because upgrading; Therefore; Some date main transformers (hereinafter to be referred as main transformer) early that put into operation often are in the oepration at full load state, thereby produce great amount of heat, and main transformer oil temperature is sharply risen; Add that to meet ambient temperature outdoor during the kurtosis summer too high, cause the ambient temperature of transformer chamber in most of old transformer station too high.
Because the job requirement of main transformer stipulates its upper strata oil temperature and must not surpass 85 ℃, otherwise, can quicken the ageing of insulation of main transformer, influence the stability of equipment if continue under hot conditions, to move.In the prior art, mainly adopt aerofoil fan to the processing of lowering the temperature of main transformer body, but owing to consider that transformer station builds along road; And the transformer chamber gate is towards being again towards road, so aerofoil fan can only be placed in the big reveal of transformer chamber; The ecto-entad blowing; Like this, can only alleviate the problem of main transformer body, great amount of heat still accumulates in the transformer chamber and can't discharge; And the heat radiation rate variance of transformer chamber, a large amount of hot gas accumulates in can't discharge in the transformer chamber, also becomes one of major reason that the main transformer body temperature can't effectively descend.This shows that the problem of transformer chamber heat radiation rate variance that solves old transformer station is extremely urgent.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists; The present invention aims to provide a kind of method that improves transformer chamber's rate of heat dissipation in the old transformer station, to improve the circulation of air performance of transformer chamber, great amount of heat can be discharged; Thereby the temperature of transformer chamber is descended, improve its rate of heat dissipation.
A kind of method that improves transformer chamber's rate of heat dissipation in the old transformer station of the present invention comprises the transformer chamber that is made up of some bodies of wall and one and the main transformer observation ward of the shared side wall body of said transformer chamber in the said transformer station, said method comprising the steps of,
Step S1 offers a partition wall hole on the body of wall between said transformer chamber and the main transformer observation ward;
Step S2 installs a ventilating fan in said partition wall hole;
Step S3 installs an exhaust duct, and an end of this exhaust duct is connected with said ventilating fan, and the other end passes said main transformer observation ward, and stretches out said transformer station.
In the method for transformer chamber's rate of heat dissipation, said partition wall hole is positioned at the position near said transformer chamber top in the old transformer station of above-mentioned raising.
In the method for transformer chamber's rate of heat dissipation, said ventilating fan is the axial-flow type ventilating fan in the old transformer station of above-mentioned raising.
Owing to adopted above-mentioned technical solution, the present invention is directed to the problem of old transforming plant main transformer chamber poor radiation, through installing ventilating fan and discharge duct on a side wall body of transformer chamber; To form an air circulation system, transformer chamber is carried out exhausting, force in the transformer chamber to exchange with outdoor air; The heat that overstocks in the transformer chamber is discharged; Thereby accelerate the circulation of air speed of transformer chamber, promote the radiating effect of transformer chamber significantly, also improved operations staff's operational environment at ordinary times simultaneously.
Description of drawings
Fig. 1 is the structural representation of transformer station among the present invention.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the present invention is elaborated.
As shown in Figure 1, comprise the transformer chamber 2 that forms by some bodies of wall 4 and one and the main transformer observation ward 3 of transformer chamber's 2 shared side wall bodies 4 in the transformer station 1.
The present invention, promptly a kind of method that improves transformer chamber's rate of heat dissipation in the old transformer station may further comprise the steps,
Step S1 on the body of wall 4 between transformer chamber 2 and the main transformer observation ward 3, offer a partition wall hole (not shown), and this partition wall hole is positioned at the position near transformer chamber 2 tops;
Step S2 one ventilating fan 5 is installed, and this ventilating fan 5 is the axial-flow type ventilating fan in the partition wall hole;
Step S3 installs an exhaust duct 6, and an end of this exhaust duct 6 is connected with ventilating fan 3, and the other end passes main transformer observation ward 3, and stretches out transformer station 1, thereby ventilating fan 5 is extracted out the heat in the transformer chamber 2, arranges to outdoor through exhaust duct 6.
After after the embodiment of the present invention, open ventilating fan 5 and test, wind direction correct position during its running after opening 1 hour, can feel obviously that the temperature in the transformer chamber 2 descends to some extent.
In sum, the present invention has advantage:
1, energy-conservation: through opening ventilating fan 5; Can accelerate the circulation of air in transformer chamber 1 space, reduce the temperature in the transformer chamber 1, thereby improve the heat radiation situation of main transformer 2; With this running time that reduces original aerofoil fan in the transformer chamber 1, reach energy-conservation effect;
2, noise reduction: ventilating fan 5 is installed in the inside of transformer station 1, and the noise that produces during its operation can not bothered the resident, simultaneously, owing to reduced the running time of original aerofoil fan in the transformer chamber 1, also can reduce the pollution that noise produces to a certain extent;
3, protection equipment: under the warm too high situation of main transformer oil; Through being used of ventilating fan 5 and original aerofoil fan; When can make the temperature decline of transformer chamber 2; Also directly cause the decline naturally of main transformer body temperature in the transformer chamber 2, thereby play the effect of effective protection equipment.
More than combine accompanying drawing embodiment that the present invention is specified, those skilled in the art can make the many variations example to the present invention according to above-mentioned explanation.Thereby some details among the embodiment should not constitute qualification of the present invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
