Abstract
The utility model relates to a self-cooling type electric power transformer, comprising an oil box, an iron core and a winding, wherein the iron core and the winding are immersed in the oil box full of transformer oil together; an oil tank shell is a square box made of a steel board; sheet-shaped heat radiators are arranged on the front wall and the back wall of the oil tank shell; oil collection pipes are arranged on the sheet-shaped heat radiators; oil collection pipes are arranged on the sheet-shaped heat radiators; the oil collection pipes are communicated with the inner cavity of the oil tank; each sheet-shaped heat radiator consists of more than two sheet-shaped heat radiation sheets; an upper cover is arranged at the upper part of the oil tank shell; the upper cover is connected with the oil tank shell by using a bolt; a tower-shaped wiring post and a conservator are arranged on the upper cover; and a mounting bracket is arranged at the bottom of the oil tank shell. An oil temperature display cabinet is arranged on one lateral face of the oil tank shell; an oil path with a pipe diameter which is the same as a pipe diameter of oil collection pipes on the sheet-shaped heat radiators or greater than the pipe diameter of the oil collection pipes; and the oil pipe is communicated with the oil collection pipe. The self-cooling type electric power transformer provided by the utility model is novel in design, so that the heat radiation effect of the self-cooling type electric power transformer provided by the utility model is good; and furthermore, the temperature of transformer oil can be measured and displayed, and the self-cooling type electric power transformer is safer and reliable to use.
Description
Technical field
The utility model relates to a kind of power transformer, particularly a kind of self cool power transformer.
Background technology
The power transformer major part of moving on the electrical network at present is oil-filled transformer.Oil-immersed power transformer has good heat dissipation, loss is little, capacity is large, price is low advantage, and it adopts complete oil-filled closed type.Fuel tank shell is the fuel tank of sealed-for-life with the expansion of self elasticity adaptation oil, and oil-filled transformer has been widely used in each controller switching equipment.For reinforced insulation and cooling condition, the iron core of transformer and winding all immerse together have been filled in the fuel tank of transformer oil.Fuel tank is the shell of oil-filled transformer, and device body (transformer core and winding) just is placed in the fuel tank of having filled transformer oil.Fuel tank generally becomes with Plate Welding, and its structural requirement has certain mechanical strength, except should satisfying the ask for something of transformer when moving, also should satisfy the ask for something of transformer when maintenance and transportation.Transformer oil has two kinds of effects, on the one hand as dielectric; As the medium of heat radiation, namely by the circulation of transformer oil, with the heat that comes out in winding and the iron core, carry out cooling on the other hand.Now oil-immersed power transformer generally is to utilize on the oil tank wall or the radiating tube that arranges or the corrugated plate that arranges the heat that comes out in cooling winding and the iron core, perhaps utilizes the gilled radiator of installing on the oil tank wall to come the heat that comes out in cooling winding and the iron core.And for the control of the heat that comes out in winding and the iron core, or be interpreted as the control of temperature of oil in transformer and show and all do not relate to.
The utility model content
The purpose of this utility model provides a kind of novel oil-filled transformer, i.e. self cool power transformer.Its structural design so that the utility model good heat dissipation effect can be measured the temperature that shows transformer oil simultaneously, makes the utility model use safety and reliability.
The utility model is achieved in that a kind of self cool power transformer, it contains fuel tank, iron core and winding, iron core and winding immerse in the fuel tank of having filled transformer oil together, tank envelope is the square chest of going to the bottom and sealing with the top opening that steel plate is made, be provided with gilled radiator on former and later two walls of tank envelope, oil collecting pipe is arranged on the gilled radiator, oil collecting pipe communicates with the fuel tank inner chamber, gilled radiator is comprised of plural chip fin, tank envelope top is provided with loam cake, loam cake is connected with bolt with tank envelope, on cover and be provided with turriform binding post and conservator, the tank envelope bottom is provided with mounting bracket, be characterized in, be provided with the oil temperature display case in tank envelope one side, have identical with oil collecting pipe caliber on the gilled radiator at chip fin middle part or greater than the oil duct of oil collecting pipe caliber, oil duct communicates with oil collecting pipe.
Useful effect
The design of the utility model novelty, so that so that the utility model good heat dissipation effect, and temperature that can measuring transformer oil, use safety and reliability.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, it contains fuel tank, iron core and winding the self cool power transformer, and iron core and winding immerse in the fuel tank of having filled transformer oil together; In the drawings, the 1st, the tank envelope of Air-cooled Power Transformer, being made by steel plate (generally is to become with Plate Welding, weld seam requires manufacturing process to accomplish non-leakage oil), tank envelope 1 is the square chest that a top opening is gone to the bottom and sealed, be equipped with two above gilled radiators 3 on two walls of tank envelope 1 front and back, respectively be provided with three gilled radiators 3 among the figure on former and later two walls; The top of tank envelope 1 is provided with loam cake 9, and loam cake 9 is connected with tank envelope 1 usefulness bolt, is provided with turriform binding post 6 and conservator 5 on the loam cake 9, and the bottom of tank envelope 1 is provided with mounting bracket 8; Oil collecting pipe 7 is arranged on the gilled radiator 3, oil collecting pipe 7 communicates with the fuel tank inner chamber, gilled radiator 3 is comprised of plural chip fin, have identical with oil collecting pipe 7 calibers on the gilled radiator at each chip fin middle part or greater than the oil duct 4 of oil collecting pipe 7 calibers, oil duct 4 communicates with oil collecting pipe 7, oil duct 4, oil collecting pipe 7 and fuel tank form the loop of an oil, and thermolysis is fabulous; Side at tank envelope 1 is provided with oil temperature display case 2, and oil temperature display case 2 is interior can to arrange oil temperature side amount, display unit, and the oil temperature warning device, at the too high alarm of oil temperature, so that the utility model uses special safety.
Version shown in the drawings also can be used as the structure of an embodiment of the present utility model.
