Abstract

The invention discloses a transformer self-generating wind cooling system. The system comprises a transformer or a transformer heat-dissipating device, wherein a coaming is arranged at the periphery of the transformer or the transformer heat-dissipating device; an inlet is formed below the coaming; the upper end of the coaming is connected with a conical top cover; and the upper end of the top cover is hermetically connected with a ventilating duct. The system is simple in structure and convenient to set. Self-generating wind formed by air pressure difference can replace fans or reduce the running quantity of the fans within a certain range, so that operating and maintenance cost of the transformer can be reduced, and vibrating influence and noise pollution are reduced. Or the work capacity of the transformer is increased under the condition of not changing the main body device of the transformer. Therefore, the system has a good application prospect.

Description

The spontaneous air cooling system of transformer
Technical field
The present invention relates to a kind of heat abstractor of strengthening the transformer heat radiation, relate to specifically the spontaneous air cooling system of a kind of transformer.
Background technology
Transformer is the visual plant of electric power system, the transformer that moves in the at present electric power system is most of to be gilled radiator, because radiating efficiency is excessively low, during greater than 50MVA, all adopt the mode that increases blower fan to improve cross-ventilation to increase heat-sinking capability in transformer capacity.But operation and maintenance cost improves behind the increase blower fan, and the on-stream vibration of blower fan easily causes weld impaired, and it also is the important noise source in the gilled radiator.
Summary of the invention
The problem to be solved in the present invention is the defective for above-mentioned prior art, provides a kind of in the situation that do not use blower fan to strengthen the spontaneous air cooling system of transformer of heat dissipating device of transformer heat-sinking capability.
In order to address the above problem, the present invention adopts following technical scheme:
The spontaneous air cooling system of a kind of transformer, comprise transformer or heat dissipating device of transformer, the periphery of described transformer or heat dissipating device of transformer is provided with coaming plate, and the below of coaming plate is provided with import, described coaming plate upper end is connected with tapered top cover, and the upper end of top cover is sealedly connected with ventilating duct.
For solar radiation in summer in winter and larger area such as the north of China of temperature difference, and transformer places outdoor situation, and described coaming plate is Demountable.
When strong and ambient temperature is higher when solar radiation such as summer, coaming plate is installed, this moment except the guiding air with the radiator of flowing through than reasonable manner, also reduced the heat that radiator obtains because of solar radiation.When weak and ambient temperature is low when solar radiation such as winter, can lay down coaming plate, strengthen radiator to the heat radiation of surrounding environment.All very strong to annual solar radiation, annual temperature is very high region such as tropical area all, perhaps places indoor transformer, and described coaming plate is non-Demountable.
The present invention is simple in structure, is convenient to arrange.The spontaneous wind that forms by draught head can replace within the specific limits blower fan or reduce fan operation quantity, thereby reduces the operation and maintenance expense of transformer, and reduces vibration effect and noise pollution.Or in the situation that do not change transformer body device raising transformer working capacity.Therefore, this system has preferably application prospect.
The invention will be further described below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Among the figure: 1-transformer or heat dissipating device of transformer; The 2-import; The 3-coaming plate; The 4-top cover; The 5-ventilating duct.
Embodiment
Embodiment, as shown in Figure 1, the spontaneous air cooling system of a kind of transformer, comprise transformer or heat dissipating device of transformer 1, the periphery of described transformer or heat dissipating device of transformer 1 is provided with coaming plate 3, the below of coaming plate 3 is provided with import 2, and described coaming plate 3 upper ends are connected with tapered top cover 4, and the upper end of top cover 4 is sealedly connected with ventilating duct 5.Tightly leak out with minimizing being connected will try one's best between ventilating duct 5 and the top cover 4, and guarantee certain ventilating duct height, the hot-air that the guiding fin rises enters ventilating duct smoothly.
Increase draught head by ventilating duct, strengthen the ventilation heat exchange effect, and air enters by the coaming plate lower inlet, discharged by ventilating duct.
The height of described ventilating duct and shape will require according to shape, size and the heat radiation of heat dissipating device of transformer concrete definite.The effect of ventilating duct is to utilize its height, increases the upwards power of the radiator air of flowing through, and improves the air stream speed of the transformer heat-delivery surface of flowing through, thereby improves air to the cooling capacity of radiator.
The coaming plate that arranges around described transformer or the heat dissipating device of transformer can design according to conditions such as local climates.
For solar radiation in summer in winter and larger area such as the north of China of temperature difference, and transformer places outdoor situation, and coaming plate can be designed to easy-to-dismount mode.
When strong and ambient temperature is higher when solar radiation such as summer, coaming plate is installed, this moment except the guiding air with the radiator of flowing through than reasonable manner, also reduced the heat that radiator obtains because of solar radiation.When weak and ambient temperature is low when solar radiation such as winter, can lay down coaming plate, strengthen radiator to the heat radiation of surrounding environment.All very strong to annual solar radiation, annual temperature is very high region such as tropical area all, perhaps places indoor transformer, and then coaming plate is non-dismountable formula.
