Abstract
The method includes steps: removing insulation on header of 10KV cable; using hydraulic tongs to fix copper connection nose on bare copper wire through cold pressing; insulator is fixed on clamping piece of transform through full screw; tapping plate and insulator is locked fixedly through screw and screw hole on insulator. Tapping leads in high voltage is prepared through following operations: fixing connector in high voltage by bolt; connecting connection straps to rated voltages; fixing lead out wire between XB phases as well as between YC phases to wiring board; passing through inside insulating rod, the lead out wire between AZ phases is fixed on the wiring board by using hexagonal copper bar. Advantages are: constant distance between lead out wires and no burr without need of packaging so as to reach purpose of safe.
Description
Technical field
What the present invention relates to is the manufacture method that a kind of SGR10 (a kind of national standard model of transformer) partly seals 10KV level transformer high-voltage pin configuration.Belong to transformer high-voltage lead-in wire manufacture technology field.
Background technology
At present, be in the dry-type transformer of magnetic conductor with the silicon steel sheet, the concrete pin configuration of epoxy SC transformer, the manufacture method of this structure is through repeatedly bending back perforate after afterbody beats out with copper tube, make the alternate lead-in wire of AZ: copper tube is beaten out the back perforate at afterbody, make the alternate lead-in wire of XB, YC: insulator is fixed in fixed insulation on the folder of transformer with full line screw rod: high-voltage connection terminal and alternate lead-in wire are fixed alternate fixing with bolt.The defective of this pin configuration is: one, copper pipe is difficult to control through reaching the distance that easily produces between burr and each lead-in wire after knocking, this phenomenon will directly have influence on transformer the office put, two, partly to seal 10KV level transformer high-voltage coil structure different fully with epoxy SC high-tension coil structure for SGR10, and epoxy SC high-voltage connection structure is not suitable for SGR10 and partly seals 10KV level transformer high-voltage pin configuration.The concrete pin configuration method of another kind of open type SG10 transformer.
The concrete pin configuration method of open type SG10 transformer, the manufacture method of this structure are through repeatedly being welded on the high-voltage tap lead after the bending with red copper bar; Make alternate lead-in wire AZ, red copper bar is welded on the high-voltage tap lead; Make the alternate lead-in wire of XB, YC, insulator is fixed in fixed insulation on the folder of transformer with full line screw rod; Live alternate lead-in wire with the edge insulator integrated circuit board, and, go between between immobile phase with insulating tape locking.Defective is one during this pin configuration, copper rod is difficult to control through reaching the distance that easily produces between burr and each lead-in wire after knocking, and the office that this phenomenon will directly have influence on transformer puts.Two copper rods need be wrapped up, and copper rod insulation Wrapping technical is cumbersome, wrap up the lead-in wire that easily causes not in place and burn.
Summary of the invention
The objective of the invention is to defective at above-mentioned existence, propose a kind of making and partly seal the method for 10KV level transformer high-voltage pin configuration, partly seal 10KV level transformer high-voltage pin configuration with what this method was made, make the fixed distance between the lead-in wire, and when making lead-in wire, do not have burr, need not wrap up the safety that may command office puts and guarantees to go between.
Technical solution of the present invention: its method step is divided into,
One, make alternate lead-in wire: the insulation of 10KV cable head is removed, expose 28-32mm, with hydraulic tongs the copper Wiring nose being colded pressing then is fixed on the exposed copper cash, makes its one-tenth as a whole, and alternate lead-in wire is promptly made;
Two, insulator is fixed: insulator is fixed on the folder of transformer with full line screw rod, insulator and transformer folder are connected and fixed;
Three, tapping plate is fixed: with bolt by the screwed hole on the insulator with tapping plate and insulator fixing and locking together;
Four, high-voltage tap lead is made:, and with brace the rated voltage retaining is connected the high tension terminal fixing and locking with bolt;
Five, alternate lead-in wire connects: with bolt lead-in wire YC between the second alternate lead-in wire XB, third phase is fixed on the terminal block, be the lead-in wire puncture that prevents that lead-in wire YC contacts and produces between the first alternate lead-in wire AZ and the second alternate lead-in wire XB, third phase, be fixed on the terminal block with insulating rod, the first alternate lead-in wire AZ is through in the insulating rod, with the hexagonal copper rod the first alternate lead-in wire AZ is fixed on the terminal block then, fixed the first alternate lead-in wire AZ and promptly guaranteed the safe insulation distance, SGR10 partly seals 10KV level transformer high-voltage lead-in wire and completes.
Advantage of the present invention: this method is made partly seals 10KV level transformer high-voltage pin configuration, the fixed distance between the alternate lead-in wire, and the no burr of lead-in wire, need not wrap up, reach the purpose that control office puts and guarantees to go between and use safely fully.

Embodiment
Embodiment partly seals the manufacture method of 10KV level transformer high-voltage pin configuration, its step branch
One, make alternate lead-in wire: the insulation of 10KV cable head is removed, expose 30mm, with hydraulic tongs the copper Wiring nose being colded pressing then is fixed on the exposed copper cash, makes its one-tenth as a whole, and alternate lead-in wire is promptly made;
Two, insulator is fixed: the full line screw rod 4 of insulator 3 usefulness is fixed on the folder of transformer, because the transformer folder is a fixed object, so insulator is promptly fixing;
Three, tapping plate is fixed: because of insulator has screwed hole, promptly available bolt 5 with tapping plate 6 and insulator 3 fixing and lockings together;
Four, high-voltage tap lead is made: use bolt 7 with high tension terminal 8 fixing and lockings, and with brace 9 the rated voltage retaining is connected;
Five, alternate lead-in wire connects: with bolt 7 the alternate lead-in wire 1 of XB, YC is fixed on the terminal block 10, be the lead-in wire puncture that prevents that the alternate lead-in wire 1 with XB, YC of the alternate lead-in wire 2 of AZ from contacting and producing, be fixed on the terminal block 10 with insulating rod 11, the alternate lead-in wire 2 of AZ is through in the insulating rod, with hexagonal copper rod 12 the alternate lead-in wire 2 of AZ is fixed on the terminal block 10 then.The alternate lead-in wire 2 of AZ is promptly fixing like this, and assurance safe insulation distance, and SGR10 partly seals 10KV level transformer high-voltage lead-in wire and completes.
