Abstract
The invention discloses a manufacturing method of resin pouring type dry transformer tapping leads. The method includes the steps of firstly, stripping the insulating paper outside the tapping leads of a high-voltage coil; secondly, cutting off the extra parts of the tapping leads according to the length required by a drawing to obtain the required tapping leads; erecting a transformer coil and moving the same to the side of a welding tool; fourthly, adjusting the up-down position of each terminal support (3); fifthly, respectively placing lead terminals on the corresponding terminal supports (3), and adjusting the positions of the terminals to allow the terminals to be in one-to-one contact with the corresponding tapping leads; sixthly, welding the tapping terminals with the corresponding tapping leads one by one; seventhly, wrapping for insulating; eighthly, performing spiral bending on each tapping lead according to the positions of the tapping terminals on a pouring die panel; ninthly, mounting a lead panel and an outer die, and pouring. By the method, short circuit faults or inconvenient die filling caused by the fact that the leads are excessively long or short are avoided.
Description
Technical field:
The present invention relates to a kind of resin filled type dry-type transformer tap lead manufacture method.
Background technology:
Resin casting dry-type transformer device body is made up of parts such as high-tension coil, low-voltage coil, iron core, core clamping, tap leads, high-tension coil needed welding lead terminal, clinched lead, installation external mold before use poured with epoxy resin, wherein terminal soldering is first cut off by certain length by lead-in wire, then solder terminal.
If 1, because wire length during lead-in wire bending is shorter, lead terminal is not in place, then cannot install external mold and pour into a mould; If wire length is longer, there is juxtaposition between lead-in wire during lead-in wire bending, very easily cause short trouble if deal with improperly.
2, because different capabilities coil height, outside dimension and wire length are different, terminal soldering special tooling versatility is not strong, causes terminal soldering inconvenient, very easily can cause short trouble if deal with improperly yet.
Summary of the invention
The technical problem to be solved in the present invention is, there is provided a kind of and avoid the go between long or too short short trouble that causes or die-filling inconvenience, adopt adjustable for height welding tooling, solve different capabilities coil height, outside dimension and wire length different and the welding inconvenience problem caused, the resin filled type dry-type transformer tap lead manufacture method that ensure that the quality of transformer.
Technical scheme of the present invention is, provides a kind of resin filled type dry-type transformer tap lead manufacture method with following steps, comprises the following steps:
(1) insulating paper outside the tap lead of high-tension coil is divested;
(2) length reserves tap lead by drawing, and is sheared by unnecessary tap lead;
(3) transformer coil is erected, and move to welding tooling side, this welding tooling it comprise chassis (1), support (2), several are for placing terminal supports (3) of lead terminals and the quantity sleeve pipe (4) corresponding with terminal support (3), the bottom of described support (2) is fixed on chassis (1), described sleeve pipe (4) successively movable noose on support (2), each sleeve pipe (4) and support (2) are provided with the bolt (5) of limit casing (4), one end of described terminal support (3) is fixed with corresponding sleeve pipe (4),
(4) upper-lower position of each terminal support (3) is adjusted, the top of corresponding terminal support (3) all can be in after making each tap lead bending, and locked bolt (5), make terminal support (3) spacing up and down;
(5) be placed in respectively by lead terminal on corresponding terminal support (3), adjustment terminal position, makes it contact one by one with corresponding tap lead;
(6) tap terminals is welded one by one with corresponding tap lead; And welding slag, wedge angle are polished flat;
(7) wrapping insulation: be first wound around wrapping ground floor with pliable and tough flame retardant fiber insulating paper successively forward, again with this flame retardant fiber insulating paper reverse-winding wrapping second layer, then be wound around wrapping third layer with 0.15*20 alkali-free glass silk ribbon, third layer wrapping direction is contrary with second layer direction;
(8) carry out spiral type according to tap terminals position on casting moulds panel to every root tap lead to bend;
(9) lead-in wire panel and external mold are installed, finally pour into a mould.
After adopting above-mentioned steps, the present invention compared with prior art, has the following advantages:
1, first will to go between bending by adopting, determining wire length, then the method for solder terminal, and avoid the long or too short short trouble that causes of lead-in wire or die-filling inconvenience, ensure that the quality of transformer.
2, by adopting adjustable for height welding tooling, solving the different and welding inconvenience problem that causes of different capabilities coil height, outside dimension and wire length, ensure that the quality of transformer.
