Abstract
The utility model discloses a transformer coil structure equipped with an air passage. The transformer coil structure mainly comprises an internal high-voltage coil and an external low-voltage coil which are coaxially arranged, wherein a plurality of air passage support strips for radiation are further arranged in the low-voltage coil, and can form an air passage in the low-voltage coil. The transformer coil structure is simple in structure and convenient for use, and the radiation area of the low-voltage pancake type coil is increased nearly by one time after the air passage for radiation is arranged in the low-voltage pancake type coil, thereby effectively solving the problem of difficult radiation of the transformer coil.
Description
Technical field
The utility model relates to a kind of and the supporting rectifier transformer field of high voltage converter, particularly be a kind of rectifier transformer loop construction that in the low pressure disc coil, is provided with air flue.
Background technology
Frequency converter is to utilize the on-off action of power semiconductor device power frequency supply to be transformed to the electric energy control device of another frequency.Along with the fast development of modern power electronics technology and microelectric technique, the high-power RHVC is constantly grown up, and the field of its application and scope also more and more are extensively, and this makes efficiently, utilizing the energy reasonablely becomes possibility.
And rectifier transformer plays the effect of insulating power supply as a most important part in the high voltage converter, has solved the pollution to electrical network of harmonic wave that high voltage converter produces in rectification, process such as contrary.At present, its inner loop construction (as shown in Figure 1) of rectifier transformer, adopt comparatively traditional structural design, the high-tension coil 1, low pressure disc coil 2, main insulating layer 3 and the insulating stay 4 that comprise coaxial placement, though in high-tension coil 1, be provided with the air flue stay that is used to dispel the heat, but outside low pressure disc coil 2 can only rely on inside and outside two radiating surfaces of coil to dispel the heat, and this has just caused the low situation of coil rate of heat dissipation, thereby reduces the operating efficiency of whole rectifier transformer.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of transformer coil structure that is provided with air flue, the lower problem of rate of heat dissipation when having the existing work of using in transformer of loop construction now to solve.
To achieve these goals, the utility model is to realize by the following technical solutions:
A kind of transformer coil structure that is provided with air flue, described transformer coil structure mainly comprises high-tension coil and the outer field low-voltage coil of coaxial arrangement at internal layer, in described low-voltage coil, also be provided with the air flue stay of a plurality of heat transmissions, and in low-voltage coil, form an air flue by described air flue stay.
When described air flue stay is assembled in low-voltage coil, carry out neat arrangement round the transformer coil axle center with the structure of annular and place.
The utility model has almost increased about one times the area of dissipation of low pressure disc coil by set up a plurality of air flues that are used to dispel the heat in the low pressure disc coil after, has effectively solved the difficult problem of frequency converter coil heat radiation.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is a kind of structural representation of traditional transformer coil.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 partly cuts open schematic diagram for the utility model low pressure disc coil
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
The purpose of this utility model is simply to improve by the structure to traditional rectifier transformer coil, solves puzzlement continues use in frequency converter the difficult problem of rectifier transformer heat radiation.
As shown in Figure 2, the utility model is a kind of transformer coil structure that is provided with air flue, in the drawings as can be seen, identical with traditional transformer coil structure, include the high-tension coil 1 that is arranged on internal layer, be arranged on the main insulating layer 3 between outer field low pressure disc coil 2, high-tension coil 1 and the low pressure disc coil 2 and axially be distributed on some insulating stays 4 on the main insulating layer periphery wall, and high-tension coil 1, low pressure disc coil 2, main insulating layer 3 and insulating stay 4 are round the axis arranged of transformer coil together.Though the coil of traditional structure is also considered the difficult problem of heat radiation when transformer uses when designing, partly be provided with the air flue of a heat transmission at high-tension coil.But be adjacent to be embedded formed low pressure disc coil 2 in the broach groove 41 of insulating stay 4 with the form of double-cake coils by main winding and phase shift winding, when work, but only can only dispel the heat the demand in the time of just can not satisfying the coil heat radiation to a great extent by its surfaces externally and internally.For this reason, an air flue just can be set separately and solve this problem in low pressure disc coil 2.As shown in Figure 3, be embedded the inside of the low pressure disc coil 2 in broach groove 41 at that, a plurality of air flue stays 6 also and outward are set, and form an air flue 5 that is used for low pressure disc coil 2 is carried out cross-ventilation heat radiation by these air flue stays 6, and these air flue stays 6 are neat being placed in the low pressure disc coil 2 of circular ring round the transformer coil axle center when assembling.
The utility model is simple in structure, by in low pressure disc coil 2, increasing the method for air flue, enlarged the area of dissipation of coil greatly, further improve the efficient of transformer heat radiation, and only need just can realize this effect by simple improvement, and after having simplified the manufacture craft that adds man-hour, the industrialized large-scale production of easier realization makes things convenient for user's use.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
