Abstract
The invention discloses a radiating structure of a buried distribution transformer, which comprises the buried distribution transformer and a pit used for accommodating the distribution transformer. The pit is a space dug downwards from the surface plane serving as the benchmark and is correspondingly covered by a cover plate. The distribution transformer is accommodated in the space; a pluralityof radiating devices are arranged between the distribution transformer and the inner wall of the pit; and the devices are sealed bag type objects filled with liquid. The invention provides the radiating structure used for radiating the buried distribution transformer. The radiating structure does not need other radiating facilities and ventilation devices under the condition of not influencing theworking of the transformer, thereby reducing the capital construction cost of the buried distribution transformer and improving the radiating efficiency of the transformer.
Description
Technical field
The present invention relates to a kind of radiator structure of distribution transformer, relate in particular to a kind of radiator structure of buried distribution transformer.
Background technology
Buried distribution transformer has more and more important position in the urban distribution network development, especially in metropolitan view street, controller switching equipment is just becoming a trend of urban development with going into.
The buried distribution transformer of domestic production at present generally all is installed in the melt pit of building in advance, guarantees that by corresponding ventilation and heat radiation facility the temperature rise of buried distribution transformer can be not too high.Therefore the safe operation of buried distribution transformer all depends on the quality of melt pit and heat radiation facility quality to a great extent, and domestic construction team is very different, and more or less always there are some big and small hidden danger in melt pit.Such hidden danger has influenced the safe operation of transformer to a great extent, so a key issue of buried distribution transformer is the temperature rise design, if it is during design that the design of temperature rise grade is higher, can suitably alleviate the hidden danger of ventilation, heat radiation aspect, but the temperature rise grade of used insulating material also must be higher, and the cost of buried distribution transformer product itself will improve greatly like this.
In melt pit, increase the facility that ventilates and dispel the heat in addition and not only expend construction period, and force melt pit to occupy suitable floor space, set air pipe must elevate above the soil, also relevant apparatus must be set on the ground, surrounding environment is caused certain influence, and in case the relevant destroyed potential safety hazard that also can cause transformer of ventilation heat abstractor.
Summary of the invention
Purpose of the present invention provides a kind of radiator structure of buried distribution transformer exactly in order to address the above problem.
The object of the present invention is achieved like this:
The invention discloses a kind of radiator structure of buried distribution transformer, comprise buried distribution transformer and the melt pit that holds distribution transformer, described distribution transformer is mainly by iron core, the low pressure winding, high pressure winding and fuel tank constitute, described iron core is arranged in the described fuel tank, the low pressure winding is arranged on the outside unshakable in one's determination, the high pressure winding is arranged on the outside of low pressure winding, described melt pit is for from the surface water plane being the space that benchmark excavates downwards, and there is corresponding cover plate to cover, described distribution transformer places in this space, it is characterized in that, be placed with several heat abstractors between described distribution transformer and the melt pit inwall, this device is an inner sealing satchel of filling full liquid.
Described satchel adopts the material with the good characteristic of insulation, waterproof, plasticity and heat conductivity.
The liquid of filling in the described satchel is water.
The invention provides a kind of radiator structure of buried distribution transformer, be used in the buried distribution transformer field, after adopting this structure, buried distribution transformer need not to ventilate on the ground, heat dissipation equipment, need not miscellaneous equipment the heat abstractor in the melt pit in buried distribution transformer and the present invention.
Adopt the present invention, low for the melt pit construction requirement, make the buried distribution transformer body carry out heat transferred in the face of land towards periphery by heat abstractor of the present invention, satisfied the temperature rise requirement when buried distribution transformer normally moves fully, there are not any heat radiation, ventilation unit simultaneously, do not influence surrounding environment fully, shortened the construction period of melt pit greatly.
Description of drawings
Fig. 1 is a plan structure schematic diagram of the present invention;
Fig. 2 be Fig. 1 along A-A ' to structural representation.
Embodiment
The present invention is described in further detail below in conjunction with drawings and embodiments.
Referring to Fig. 1, Fig. 2, the invention discloses a kind of radiator structure of buried distribution transformer, comprise buried distribution transformer 1 and the melt pit 2 that holds distribution transformer, described distribution transformer 2 is mainly by iron core, the low pressure winding, high pressure winding and fuel tank constitute, described iron core is arranged in the described fuel tank, the low pressure winding is arranged on the outside unshakable in one's determination, the high pressure winding is arranged on the outside of low pressure winding, described melt pit 1 together with described distribution transformer 2 landfills in underground, be provided with several satchels 3 between described distribution transformer 2 and the melt pit 1, these satchel 3 inner filling water and sealings, because it is very big that specific heat of water holds, the heat that transformer distributes can be absorbed by water bag rapidly, this will improve the radiating efficiency of transformer greatly, this satchel 3 is by having insulation, waterproof, the material of characteristics such as plasticity and heat conductivity are good is made, as insulating heat-conductive silicon.
If when the size of described satchel 3 is consistent, be respectively equipped with at least one satchel 3 around the distribution transformer, in order to fill up the gap between distribution transformer 2 and the melt pit 1.
If during not of uniform size the causing of described satchel 3, be respectively equipped with at least one satchel 3 around the distribution transformer, in order to fill up the gap between distribution transformer 2 and the melt pit 1.
The present invention proposes a kind of radiator structure, be used for the heat radiation of buried transformer, this radiator structure need not other heat radiation facility and ventilation equipment under the situation that does not influence transformer work, reduce buried transformer capital construction construction cost, improved the transformer radiating efficiency.
Above embodiment is only for the usefulness that the present invention is described, but not limitation of the present invention, person skilled in the relevant technique, under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
