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.

Technical field：
The present invention relates to a kind of resin filled type dry-type transformer tap lead preparation method.
Background technology：
Resin casting dry-type transformer device body is by portions such as high-tension coil, low-voltage coil, iron core, core clamping, tap leads
Part is constituted, and high-tension coil was needed welding lead terminal, clinched lead before using poured with epoxy resin, installs external mold, its middle-end
Son welding is first to cut off lead by certain length, then solder terminal.
If the 1st, due to during lead bending wire length it is shorter, lead terminal is not in place, then cannot install external mold and be poured into a mould；
If wire length is longer, there is juxtaposition between lead during lead bending, if dealing with improperly easily cause short trouble.
2nd, because different capabilities coil height, outside dimension and wire length are different, terminal welding special tooling versatility
It is not strong, cause terminal welding inconvenient, if dealing with improperly also can easily cause short trouble.
The content of the invention
The technical problem to be solved in the present invention be to provide it is a kind of come avoid lead long or the too short short trouble for causing or
Die-filling inconvenience, using adjustable for height welding tooling, solve different capabilities coil height, outside dimension and wire length it is different and
The resin filled type dry-type transformer tap lead preparation method of the inconvenient problem of welding for causing, the quality that ensure that transformer.
The technical scheme is that, there is provided a kind of resin filled type dry-type transformer tap lead having steps of
Preparation method, comprises the following steps：
(1) insulating paper outside the tap lead of high-tension coil is divested；
(2) by drawing length reserves tap lead, and unnecessary tap lead is sheared；
(3) transformer coil is erected, and be moved to welding tooling side, the welding tooling it include chassis (1),
Frame (2), several terminal support (3) and quantity sleeve pipes (4) corresponding with terminal support (3) for placing lead terminal are described
The bottom of support (2) is fixed on chassis (1), described sleeve pipe (4) successively movable noose on support (2), each sleeve pipe (4) with
Support (2) is provided with the bolt (5) of limit casing (4), and one end of the terminal support (3) is fixed with corresponding sleeve pipe (4)；
(4) upper-lower position of each terminal support (3) is adjusted, makes each tap lead can be in corresponding terminal after bending
The top of support (3), and locked bolt (5), make terminal support (3) spacing up and down；
(5) lead terminal is respectively placed on corresponding terminal support (3), adjusts terminal position so as to corresponding point
Connect lead to contact one by one；
(6) tap terminals are welded one by one with corresponding tap lead；And welding slag, wedge angle are polished flat；
(7) wrapping insulation：First with flexible flame retardant fiber insulating paper successively positive winding wrapping ground floor, then use this
Kind of the flame retardant fiber insulating paper reverse-winding wrapping second layer, then with 0.15mm*20mm alkali-free glass wools band winding wrapping the
Three layers, third layer wrapping direction is in opposite direction with the second layer；
(8) screw type bending is carried out to every tap lead according to tap terminals position on casting moulds panel；
(9) lead panel and external mold are installed, are finally poured into a mould.
After above-mentioned steps, the present invention compared with prior art, with advantages below：
1st, by using first by lead bending, determining wire length, then the method for solder terminal is avoiding lead long
Or the too short short trouble for causing or die-filling inconvenience, it is ensured that the quality of transformer.
2nd, by using adjustable for height welding tooling, solving different capabilities coil height, outside dimension and wire length
The different and welding inconvenience problem that causes, it is ensured that the quality of transformer.
