Each stay and cushion block constitute the support frame of transformer body, and low-voltage coil 13, high-tension coil 15 all are fixed at vertical and horizontal.Each stay makes and forms heat dissipation channel longitudinally in the transformer body, and the heat that distributes in the transformer running dispels the heat by heat dissipation channel.Each stay is the key factor of decision transformer body heat dispersion, mechanical strength, also is one of key factor of improving the quality of products.
The main effect of second insulating paper cylinder 14 be since high-tension coil 15, low-voltage coil 13 according to technology and equipment must be separately around, carry out integral assembling then: earlier respectively with on first stay 16 of low-voltage coil 13 outside first insulating paper cylinder 12,19 of adjacent low pressure cushion blocks, on the 3rd stay 18 of high-tension coil 15 outside second insulating paper cylinder 14, between the adjacent high pressure cushion block 20, again second insulating paper cylinder 14 is enclosed within outside the good low-voltage coil of coiling 13.
15 of low-voltage coil 13 and high-tension coils are master control road 21, master control road 21 mechanical distance are minimum to be 19mm (7mm second stay 17+1mm suit gap+4mm second insulating paper cylinder 14+7mm the 3rd stay 18), and low-voltage transformer electrical distance only needs 8.5~13mm, this makes winding volume bigger, and because low-voltage coil 13 and 15 of high-tension coils are provided with second insulating paper cylinder 14, vertically heat dissipation channel is divided into two halves, influences radiating effect.
Summary of the invention
The purpose of this utility model provide the mechanical distance in a kind of master control road and electrical distance quite, little from heavy and light, volume, save the transformer body that cost, good heat dissipation effect, production process are simplified.
To achieve these goals, transformer body of the present utility model is by the following technical solutions: a kind of low-voltage transformer body, comprise iron core, insulating cylinder, low-voltage coil, high-tension coil, their concentrics, and from the internal layer to the skin, be arranged in order, be interval with first stay longitudinally between low-voltage coil and the insulating cylinder, be interval with second stay longitudinally between low-voltage coil and the high-tension coil, first stay outside is interval with the low pressure cushion block, low-voltage coil is on first stay, and between adjacent low pressure cushion block, second stay outside is interval with the high pressure cushion block, high-tension coil is on second stay, and on same second stay between the adjacent high pressure cushion block, second stay is inboard to be connected with the low pressure cushion block.
There is projection both sides, the described first stay outer end, low pressure cushion block the inner, the outer end is fluted respectively, second stay the inner, the both sides, outer end have projection respectively, high pressure cushion block the inner is fluted, and the projection of described first stay embeds in the groove of low pressure cushion block the inner, and the projection of described second stay the inner, both sides, outer end embeds respectively in the groove of low pressure cushion block outer end, high pressure cushion block the inner.
Compare with prior art, the utility model has the advantages that:
1, by change the stay structure and save paper web reduce the master control track pitch from, thereby the mechanical distance and the electrical distance that reach the master control road are suitable; Under equal voltage, can dwindle insulation distance, thereby make structure of transformer body compacter, alleviate the deadweight and the volume of transformer body, prolong the useful life of transformer.
2, when making transformer body of the present utility model, can be earlier with after between the low pressure cushion block of first stay of low-voltage coil outside insulating cylinder, second stay is installed again, then high-tension coil along the circumferential direction is wound on the high-voltage cushion interblock of second stay.Must be separately than original high and low pressure coil around, the step of carrying out integral assembling then is more convenient, has simplified operation.
3, save paper web, saved cost.
4, save paper web, originally the heat dissipation channel on paper web both sides merges, and it is big that heat dissipation channel becomes, and accelerates to take away the heat that transformer produces, and has strengthened radiating effect.
