Abstract
The utility model provides a stereo-triangular wound core dry type transformer, which mainly comprises a stereo-triangular wound core, a high voltage coil, a low voltage coil, a support rack, a clamping element and a thread outgoing end. The stereo-triangular wound core dry type transformer is characterized in that each turn of the coils of the high and the low voltage coils is wrapped-around with an insulating layer which can bear the temperature of 180DEG C and above that, and has flame resistance and high electric mechanical strength, and one layer of insulating varnish, which is soaked by vacuum pressure and can bear the temperature of 180DEG C and above that and has moisture resistance and high electric mechanical strength, is attached to the stereo-triangular wound core, the high voltage coil and the low voltage coil. The stereo-triangular wound core dry type transformer has the advantages of maintenance free, running cost saving, and wide application range.
Description
Technical field: the utility model relates to a kind of improved power transformer, particularly a kind of 3-D triangle coil iron core dry-type transformer.
Background technology: for a long time, electrical transformer cores mostly is the planar alignment laminated structure, the deficiency of this kind structure is that magnetic circuit is asymmetric, magnetic resistance is big, no-load current is big, noise is big when no-load loss height and operation, deficiency at this kind structure, patented technology: 99114376.0 and 00220995.0 has proposed a kind of cubic three phase transformer iron core with round section and triangle iron core transformer respectively, this kind iron core and transformer magnetic circuit symmetry, magnetic resistance is little, no-load current is little, no-load loss is low, the operation noise is low, and it has played a strong progradation to the development of transformer.But triangle core iron core transformer only is a kind of oil-immersed power transformer, it mainly by triangle iron core, be wound on low, high-tension coil, support, the fuel tank on the triangle iron core post and be poured in insulating oil constitute.Wet type transformer deficiency in use has: 1, use face is narrower, and this fire fail safe that is it is lower, in high buildings and large mansions, residential quarter and the need fire prevention general bad use in place.2, need periodic maintenance, increased workload and operating cost.
Summary of the invention: the purpose of this utility model be at wet type triangle iron core transformer in use deficiency and a kind of dry type triangle iron core transformer is proposed, thereby better solve the deficiency that oil immersed type triangle iron core transformer in use exists, it has structurally removed the former fuel tank and the insulating oil of Qi Nei, and has carried out corresponding improvement.
Can realize the purpose of this utility model by following technical proposals, a kind of 3-D triangle coil iron core dry-type transformer, comprise by three identical, the assembled tridimensional triangle iron core of single-phase iron core of reeling and forming with continuous silicon strip, be wound on the height on the triangle iron core post, low-voltage coil, cylindrical stent, it is characterized in that at height, hold on every circle coil in the low-voltage coil heat-resisting 180 ℃ and more than, fire protection flame retarding, the insulating barrier that electricapparatus intensity is high, tridimensional triangle iron core reaches the height around thereon, low coil integral body is adhered to one deck by vacuum pressure impregnation, heat-resisting 180 ℃ and more than, moisture resistance, the insulating varnish of high electricapparatus intensity.
Effect of the present utility model is, 1, fire line is good, can anti-higher temperature, and thereby being had, it uses wide advantage, no matter residential quarter, the high buildings and large mansions place that has higher requirements that still prevents fires is all applicable.2, non-maintaining, saved operating cost, reduced workload, this is that mainly transformer integral body passed through vacuum pressure impregnation, makes that it adheres to that one deck is heat-resisting, due to the insulating varnish of moisture resistance and high electricapparatus intensity.
Below in conjunction with accompanying drawing and the utility model is described in further detail.
Description of drawings:
Accompanying drawing 1 is the utility model embodiment partial sectional view;
Accompanying drawing 2 is the vertical view of accompanying drawing 1.
Embodiment: referring to accompanying drawing 1,2, outside the iron core column of 3-D triangle volume iron core 1 (hereinafter to be referred as iron core), be surrounded by one and involute the coil brace 6 of tubular, be wound with high-tension coil 4 and low-voltage coil 5 on it by two insulating trips.Be wound with heat-resisting 180 ℃ and above, fire protection flame retarding, insulating barrier that electricapparatus intensity is high on every circle in high-tension coil 4 and the low-voltage coil 5.The material of this insulating barrier can be the NOMEX paper tape, also can be with it to have identical or close materials with function.Iron core 1 with adhere to heat-resisting 180 ℃ and above, the moisture resistance of one deck by vacuum pressure impregnation, the insulating varnish of high electricapparatus intensity around high and low pressure coil 4,5 integral body thereon.Clamping element 3 clamps iron core 1, is provided with lead-in wire and lifts one's head 2 on clamping element 3.
Claims (1)
