For further strengthening insulation, U-shaped insulation layers are arranged on both outer side edges of the framework. Obviously, the utility model with the structure can sufficiently ensure the insulation required by a safety requirement and raise the rate of finished products. The enhanced insulation power transformer has the advantages of low raw material cost, energy saving and simple and practical process.
Description
Technical field:
The utility model relates to a kind of power transformer that generally uses, and more specifically says so about strengthening and the power transformer that the heavy insulation of required electric leakage of power transformer and safety requirements is provided.
Background technology:
At present, known power transformer as a kind of to the very strict soft magnetism electromagnetic component of security requirement, its function is that power transmission, voltage transformation and insulation are isolated, worker's type of widespread usage, the blade inserting transformer of king's type structure, this class transformer coil processing is simple, and coiling is convenient, but dielectric strength and insulation distance that product often occurs do not reach the safety index requirement, and can not provide required electric leakage and safety requirements, product fraction defective height, in use failure rate height.
Summary of the invention:
The utility model purpose is for guaranteeing required electric leakage and the safety requirements of transformer, improve reliability of products and rate of finished products, lower raw-material material consumption simultaneously, energy savings and a kind of power transformer of heavy insulation is provided has overcome the problem that prior art exists.
The technical solution of the utility model is the basic insulation except between transformer and secondary coil and iron core, again specially between transformer primary and secondary coil and and iron core between stick on the U-shaped insulating barrier, to guarantee between the primary and secondary coil of transformer and to leave enough surface creepage distance and insulation distance between coil and iron core, provide product required safety requirements.Sticking on width, length and the thickness of insulating barrier can regulate by the product safety structure is required.
Therefore, the utility model comprises primary coil and the external insulation layer of primary coil and the external insulation layer of secondary coil and secondary coil thereof on the skeleton that is wound on iron core, it is characterized in that it also is included in along skeleton two inner side edges will be provided with the insulating barrier of U-shaped on primary coil or the secondary coil.
Consider further heavy insulation, be provided with the insulating barrier of U-shaped in two outer side edges of skeleton again.
Above-mentioned insulating barrier is selected the insulating tape of commercially available high-quality for use.
The beneficial effects of the utility model are that the transformer technological operation is simple, and is economical and practical, the cost performance height.Be mainly reflected in: 1) between the primary and secondary coil of transformer and the dielectric strength between iron core and surface creepage distance reach requirement and strengthened; 2) the transformer characteristic fraction defective lowers, and reduces loss, thereby has saved the energy.Therefore, the utility model can guarantee electric leakage and the safety requirements that transformer is required, has strengthened product market competitiveness.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is worker's type structure embodiment partial structurtes profile of the present utility model.
Fig. 2 is king's type structure embodiment partial structurtes profile of the present utility model.
Wherein 1 iron core, 2 skeletons, 3 primary coils, 4 secondary coils, 5 insulating barriers, 6 primary coil external insulation layers, 7 secondary coil external insulation layers, 8 skeleton external insulation layers.
Embodiment
The utility model comprises the external insulation layer 7 of external insulation layer 6, secondary coil 4 and the secondary coil thereof of primary coil 3 on the skeleton 2 that is wound on iron core 1 and primary coil thereof, it is characterized in that it also is included in along skeleton two inner side edges primary coil 3, or secondary coil 4 is provided with one or more layers U-shaped insulating barrier 5.Be that U-shaped insulating barrier 5 is arranged on the high-tension coil of transformer, as corresponding worker's type structure transformer, U-shaped insulating barrier 5 is arranged on the primary coil 3, and as Fig. 1, and as corresponding king's type structure transformer, U-shaped insulating barrier 5 is arranged on the secondary coil 4.
Also can be provided with one deck or two layers of U-shaped skeleton external insulation layer 8 again in two outer side edges of skeleton 2.
Above-mentioned U-shaped insulating barrier 5 and 8 is insulating tapes.
Among Fig. 1, as embodiment 1, primary coil external insulation layer 6 is the basic insulations between primary coil 3 and the secondary coil 4 around the width of full whole skeleton 2 with worker's type structure transformer.On primary coil external insulation layer 6,2 liang of inner side edges of skeleton are sticked on the three-layer insulated layer 5 of well cutting, secondary coil 4 is clipped between the U-shaped insulating barrier, between primary and secondary coil, just can guarantee enough surface creepage distances and insulation fully like this, secondary coil external insulation layer 7 is placed on the outside of secondary coil, coil is finished before the dowel core 1, and sticking on two-layer skeleton external insulation layer 8 again in 2 liang of outsides of skeleton is that transformer is handled through dual heavy insulation.The insulating tape width just can guarantee enough surface creepage distances and insulation fully like this by required cutting between coil and iron core.
Among Fig. 2, with king's type transformer as embodiment 2, primary coil 3 and secondary coil 4 be not at same winding slot, there is a dividing plate centre, before the primary coil coiling, corresponding winding slot two inboards at skeleton 2 add one or more layers insulating barrier 5, insulating tape width, length, thickness are by required cutting, and primary coil 3 is clipped between the U-shaped insulating barrier.Secondary coil 4 coiling according to a conventional method, between primary and secondary coil, just can guarantee enough surface creepage distances and insulation fully like this, coil is finished before the dowel core 1, add obedient skeleton external insulation layer 8 in 2 liang of outsides of skeleton, the insulating tape width just can guarantee enough surface creepage distances and insulation fully like this by required cutting between coil and iron core.
Obviously, the utility model of constructing thus can fully guarantee the insulation that safety requirements is required, improves rate of finished products, and cost of raw material attenuating, has saved the energy, features simple and practical process.
