Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of transformer with elastic layer, it can effectively solve coil in the transformer of prior art and dielectric expanded by heating and extruding will produce crack and affect the job stability of transformer and the problem of insulating properties under long-term work mutually, reach the job stability and the insulating properties that improve transformer, and the object increasing the service life.
For achieving the above object, the utility model provides following technical scheme: a kind of transformer with elastic layer, comprise housing and skeleton, in described housing, be perfused with dielectric, described skeleton is provided with primary coil wound portion and secondary coil wound portion, in described primary coil wound portion, be wound with primary coil, described primary coil outsourcing is provided with the first elastomeric isolation circle; In described secondary coil wound portion, be wound with secondary coil, described secondary coil outsourcing is provided with the second elastomeric isolation circle, described the first elastomeric isolation circle and the second elastomeric isolation circle are heat proof material, described the first elastomeric isolation circle is packaged in outside primary coil, and described the second elastomeric isolation circle is packaged in outside secondary coil.
By adopting technique scheme, after transformer long-term work, coil will produce a large amount of heat, these heat also will pass in dielectric, owing to being provided with, make their elastic layers in coil and dielectric, coil and dielectric can mutually not push because of expanded by heating and form crack, can play by the elastic layer between them effect of a buffering, when primary coil and dielectric are during at expanded by heating, fully by elastomeric isolation circle, cushioned, when secondary coil and dielectric are during at expanded by heating, fully by elastomeric isolation circle, cushioned, thereby improve job stability and the insulating properties of transformer, and increase the service life.
The utility model is further set to: described dielectric is epoxy resin.
By adopting technique scheme, select epoxy resin to be that dielectric not only has closely knit, water resistant, anti-leakage are good, intensity high, have the good manufacturabilities such as strong adhesion, normal-temperature operation, easy construction simultaneously, and also moderate.
The utility model is further set to: between described primary coil wound portion and secondary coil wound portion, be provided with division board.
By adopting technique scheme, the process that is wound into corresponding primary coil wound portion and secondary coil wound portion at primary coil and secondary coil is done, by the method for division board is set, make primary coil and secondary coil be isolated insulation completely and open, job stability is improved.
The utility model is further set to: described skeleton is connected with fin, and described fin is provided with jointing holes, and described skeleton is arranged in jointing holes.
By adopting technique scheme, pass through fin, the large calorimetric that can effectively transformer be produced at work fast conduction distributes, because heat is distributed rapidly, also greatly reduced coil and dielectric due to the degrees of expansion of being heated, improved significantly job stability and increased the service life.
The utility model is further set to: described skeleton is provided with the spacing preiection for spacing fin.
By adopting technique scheme, when fin is set on skeleton, by the spacing preiection arranging on skeleton, can fin accurately be facilitated to such an extent that be limited on skeleton, when transformer is received vibrations at work, still can stably be set on skeleton, improved job stability.
The utility model is further set to: described skeleton is removably connected with contact pin.
By adopting technique scheme, do not regulating or the constant moving winding number of turn in the situation that, can, by regulating contact pin position, realize easily the object that changes the input coil number of turn and the output winding number of turn; By adjusting contact pin quantity, realize easily and increase or reduce the objects such as output voltage number.
Compared with prior art, the utility model has the advantage of: after transformer long-term work, coil and dielectric can mutually not push because of expanded by heating and form crack, can play by the elastic layer between them effect of a buffering, thereby improve job stability and the insulating properties of transformer, and increase the service life.
