Abstract
The utility model provides a pressing plate of a body of a transformer with channels. Grooves are arranged on one face of a traditional pressing plate, or insulation paper plate bars (or other insulation material bars) are pasted on the face of the traditional pressing plate to form longitudinal channels or horizontal channels. The channels and oil channels of coils form a circulation path for oil of the transformer, and therefore, the oil of the transformer can flow smoothly, and the purpose of quick heat dissipation of the coils is achieved.
Description
Technical field
The utility model is a kind of transformer body pressing plate, is placed between transformer coil and the iron yoke, belongs to the power distribution equipment technical field.
Background technology
At present, in transformer was made, the pressing plate that generally uses was to be formed by the electrical laminated wood cutting, and surfacing is placed between transformer coil and the upper and lower iron yoke, played support coils, strengthened insulating between coil and iron yoke.But, in oil immersed amorphous alloy iron core distribution transformer, pressing plate directly is placed on the radial both ends of the surface of coil, the blocking coil oil duct, transformer oil can't be circulated, and then the heat of coil generation can't be conducted by transformer oil, cause easily the transformer coil temperature rise value to surpass design load and national Specification value, the acceleration insulating material is aging, shortens transformer useful life.
Summary of the invention
Cause the shortcoming of blocking oil duct in order to overcome above-mentioned pressing plate, the utility model provides a kind of pressing plate, and this pressing plate can not only play support coils, strengthen insulating between coil and iron yoke, and the guide path of transformer oil circulation can also be provided for the coil oil duct.
The technical scheme that its technical problem that solves the utility model adopts is: according to the arrangement of coil oil duct, with milling machine common pressing plate is slotted, or paste insulating paper lath (or other insulating material bars) in the one side of common pressing plate, form vertical and horizontal raceway groove (lateral channel is to guarantee that pressing plate rises coil under the prerequisite that insulate between excellent support and reinforcement coil and iron yoke, arranges the number that needs).These raceway grooves should slightly be wider than oil duct, and it is smooth and easy to be convenient to the transformer oil circulation.When transformer moved, coil produced heat and conducts to transformer oil, the transformer oil expanded by heating, and the guiding raceway groove on oil duct and pressing plate can circulate.
The beneficial effects of the utility model are, support coils and strengthen coil to core insulation in, the cold oil of also being convenient to the transformer-cabinet bottom passes through pressing plate raceway groove concentrated supply in the coil oil duct, reach the purpose of the heat of the coil generation that leaves fast, make coil temperature rise reach design load and national Specification value, and then guarantee the useful life of transformer.

Fig. 1 is that the pressing plate master looks schematic diagram;
Fig. 2 is the pressing plate schematic top plan view;
Fig. 3 is the pressing plate schematic side view;
Note among the figure: 1, insulating paper lath (when pressing plate adopted the electrical laminated wood fluting to make, this place and 4 was all monoblock lamination wood);
2, the longitudinal channel of pressing plate;
3, the lateral channel of pressing plate;
4, electrical laminated wood.
Embodiment
Manufacturing has dual mode with the pressing plate of raceway groove.A kind of is shown in accompanying drawing 1,2,3, presses the oil duct arrangement position on the coil, pastes the insulating paper lath at electrical laminated wood (4), forms the vertical and horizontal raceway groove; Another kind is shown in accompanying drawing 1,2,3, and insulating paper lath (1) and electrical laminated wood (4) are the monoblock electrical laminated wood, also are by the oil duct arrangement position, to the processing of slotting of monoblock lamination wood, obtains the vertical and horizontal raceway groove.Wherein lateral channel is to guarantee that pressing plate rises coil under the prerequisite of insulating effect between excellent support and reinforcement coil and iron yoke, arranges the number that needs.These vertical and horizontal raceway grooves all slightly are wider than the oil duct width.
Claims (1)
1. the transformer body pressing plate with raceway groove is characterized in that having on the surface vertical and horizontal raceway groove.
