Abstract
The invention discloses a transformer. The transformer comprises a box body, a coil, an iron core, an evaporator, a condenser, a first pipeline and a second pipeline, wherein the coil and the iron core are located inside the box body, insulating oil is filled into the box body, the evaporator is immersed in the insulating oil in the box body, an upper port and a lower port are arranged on the evaporator, the condenser is provided with an upper port and a lower port, the upper port of the condenser is communicated with the upper port of the evaporator through the first pipeline, and the lower port of the condenser is communicated with the lower port of the evaporator through the second pipeline. The transformer is simple in structure, high in heat dissipation efficiency, and capable of saving space greatly due to the fact that a transformer body can be placed underground.
Description
Technical field
The present invention relates to a kind of transformer.
Background technology
Power transformer has obtained extensive use as a kind of visual plant in the electric power system in the power engineering field.In the transformer running, the heat part of generation has been used for promoting winding and itself temperature unshakable in one's determination, and another part passes to the casing wall by transformer oil with convection current and heat conducting mode, thereby part temperatures such as the pasta of transformer and winding are raise.Can make too high aging quickening of insulating part that causes its transformer inside of winding temperature of transformer if do not take measures, insulation life shortens, and transformer can't normally move.In addition, along with the continuous increase of transformer single-machine capacity, the weight and volume of transformer also will increase thereupon, but is subjected to the restriction of floor space and transport capacity, and the weight and volume of transformer can not increase always, the underground substation, city more and more occurred.Because the sealing of its space, the natural draft condition is relatively poor, generally transformer body is installed on undergroundly, and cooling device is installed on the face of land, and therefore, traditional type of cooling has been subjected to very big restriction.Therefore, design suitable structure, manufacturing is dispelled the heat strong, safe and reliable and can be placed underground transformer is the direction that the applicant is devoted to make great efforts.
Summary of the invention
The objective of the invention is to overcome provides a kind of transformer, simple in structure, the radiating efficiency height, and main body can be placed in undergroundly, saved the space greatly.
The technical scheme that realizes above-mentioned purpose is:
A kind of transformer comprises casing, and the coil and the iron core that place box house, and described transformer also comprises evaporator, condenser, first pipeline and second pipeline, wherein:
Be full of insulating oil in the described casing;
Described evaporator is immersed in the insulating oil of described box house, and it is provided with upper and lower two ports;
Described condenser is provided with upper and lower two ports, and the upper port of condenser is connected described upper end of evaporator mouth by described first pipeline; The lower port of condenser is connected the lower port of described evaporator by described second pipeline.
Above-mentioned transformer wherein, is full of cooling fluid in described second pipeline and the evaporator.
Above-mentioned transformer, wherein, described cooling fluid is freon R-113.
Above-mentioned transformer, wherein, the upper port of the logical described condenser of a termination of described first pipeline, the sidewall of the described casing of other end hermetically passing is also connected described upper end of evaporator mouth; The lower port of the logical described condenser of one termination of described second pipeline, the sidewall of the described casing of other end hermetically passing is also connected the lower port of described evaporator.
Above-mentioned transformer, wherein, the residing height of described condenser is higher than the residing height of described casing.
The invention has the beneficial effects as follows: the present invention is by utilizing the difference in height between condenser and the evaporator, and realization is placed in transformer body underground, and condenser is placed mounting means on the ground, has saved the space greatly.Simultaneously, the present invention is simple in structure, is easy to realize the radiating efficiency height.
Description of drawings
Fig. 1 is the structural representation of transformer of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
See also Fig. 1, transformer of the present invention comprises casing 1, places coil 2, iron core 3 and evaporator 4, condenser 5, first pipeline 6 and second pipeline 7 of casing 1 inside, wherein:
Be full of insulating oil in the casing 1, coil 2, iron core 3 and evaporator 4 all are immersed in the insulating oil of casing 1 inside;
Evaporator 4 is provided with upper and lower two ports, and condenser 5 is provided with upper and lower two ports;
The upper port of the logical condenser 5 of one termination of first pipeline 6, the sidewall of the other end hermetically passing casing 1 of first pipeline 6 is also connected the upper port of evaporator 4;
The lower port of the logical condenser 5 of one termination of second pipeline 7, the sidewall of the other end hermetically passing casing 1 of second pipeline 7 is also connected the lower port of evaporator 4;
Be full of cooling fluid in second pipeline 7 and the evaporator 4, in the present embodiment, cooling fluid is freon R-113.
Principle of the present invention: for evaporator 4, therefore outside ambient temperature absorbs heat than temperature inside height; For condenser 5, ambient temperature on every side is lower than temperature inside, so release heat.Cooling fluid in the evaporator 4 absorbs the heat vaporization, and the steam after the vaporization arrives in the condensers 5 along first pipeline 6, because the ambient temperature of condenser 5 is lower than internal temperature, so steam is emitted heat and is condensed into liquid.Again because condenser 5 than evaporator 4 position height, then cooling fluid circulates automatically, need cooling fluid be moved by external impetus (as pump).
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.
