Abstract
The utility model discloses an oil duct of a transformer, which is provided with at least two pieces of core laminations, cold rolling lining plates are arranged on the core laminations, an oil duct buckle is riveted on each cold rolling lining plate for separating each core lamination, the oil duct buckles are made from phenolic resin material, and are distributed on the cold rolling lining plates with a certain pitch and row space in a point shape and in a physical riveting mode. The utility model greatly improves the reliability, the heat dissipation efficiency and the compression strengthof an iron core oil duct, reduces the noise, saves the manufacturing time and labor, has high efficiency and low cost simultaneously.
Description
Technical field
The utility model relates to a kind of transformer oil duct.
Background technology
Oil-filled transformer can produce a large amount of heat under actual working state, this just need cool off voltage transformer system with cold oil, traditional oil duct unshakable in one's determination is provided with forms such as adopting insulating paper lath, ceramics or glass bar stickup and makes, though its shared proportion is little, but in long-term use, the variations in temperature of transformer can influence the viscosity of super glue, causes the hidden danger that comes off, and especially has outstanding performance during the yoke part on unshakable in one's determination inserting; The shrinkage of insulating paper lath can influence colligation tightness unshakable in one's determination, thereby causes the increase of noise; Ceramics and glass bar belong to fragile article, are subjected to very big thrust unshakable in one's determination, the probability height that it is broken; And traditional oil duct making time and effort consuming unshakable in one's determination, efficiency is low, the cost height.
The utility model content
The technical problems to be solved in the utility model is: transformer noise is big in order to solve, the low and caducous phenomenon of oil duct button that sticks with glue of heat radiation, and the spy provides the transformer that a kind of noise is low, radiating efficiency is high, reliability is high oil duct.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of transformer oil duct, have at least two core laminations, core lamination is provided with cold rolling liner plate, riveted joint is useful on the oil duct button that each core lamination is separated out the gap on each cold rolling liner plate, between core lamination, form oil duct unshakable in one's determination like this, be convenient to internal heat dissipating unshakable in one's determination.
Described oil duct button adopts phenolic resin material to make, and to improve its anti-high pressure ability, shrinkage reduces simultaneously, has guaranteed the colligation tightness to iron core, reduces operating noise, also can adopt other insulating material.
In order to be separated out the gap between each core lamination, described oil duct button is that disk is buckled shape.
In order to make in the oil duct unshakable in one's determination the oil circulation smooth, omnidirectional, oil stream zone is big, and radiating efficiency height, described oil duct are buckled in and adopt physics riveted joint mode to be spot distribution by certain array pitch, line-spacing on the cold rolling liner plate.
The beneficial effects of the utility model are: improved the reliability of oil duct unshakable in one's determination greatly, radiating efficiency and compression strength; Reduced noise, and make time saving and energy saving, efficient is high, cost is low.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Wherein: 1. core lamination 2. cold rolling liner plate 3. oil duct buttons.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of transformer oil duct as shown in Figure 1, has three core laminations 1, and core lamination 1 is provided with cold rolling liner plate 2, and riveted joint is useful on the oil duct button 3 that each core lamination 1 is separated out the gap on each cold rolling liner plate 2; Oil duct button 3 adopts insulating material making such as high-strength phenolic resin; Oil duct button 3 is that disk is buckled shape, adopts physics riveted joint mode to be spot distribution by certain array pitch, line-spacing on cold rolling liner plate 2.
This transformer oil duct is when work, and the thickness by the oil duct button 3 of riveting on cold rolling liner plate 2 isolates a lot of gap with oil-immersed type transformer, cold oil circulates between the slit, and deep fat flows out, and cold oil flows to again, constantly back and forth, guarantee the cooling-down effect of transformer core.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.
