Technical field
The utility model belongs to electrical equipment technical field, and in particular to a kind of dry-type transformer low-pressure line-outgoing row.
Background technique
Low-voltage coil of dry type transformer of the capacity greater than 315kva or more is mostly using copper foil coiling, and foil is around the low of coiling
What the outlet row of crimping circle generally used is all whole copper bar, occupies sky in the part chamfering that copper bar and foil weld to reduce copper bar
Between.The advantages of this outlet row is that structure is relatively reliable, and blanking is relatively easy, but chamfering needs special milling machine and substantial increase
Working hour, whole copper bar cannot reach maximum by the utilization rate of outlet row, waste material.
And due between the upper clamping piece of transformer and interior outlet row, between inside and outside outlet row, and outer outlet row and wiring
It needing to connect between row, existing outlet row mostly uses to be connected for three layers one by one up and down, so, the lead division length of outlet row
Also it further increases, not only occupied space is big, also more wastes material.
Utility model content
For above-mentioned problems of the prior art, the utility model provides a kind of dry-type transformer low-pressure line-outgoing
Row, structure is simple, easy to process, and copper bar material, save the cost are utilized to greatest extent.
To achieve the goals above, the technical scheme adopted by the utility model is that:
A kind of dry-type transformer low-pressure line-outgoing row, including transformer "] " type upper clamping piece and out of low-voltage coil extraction,
It is logical to offer first there are three mounting plate for outer outlet row, the lower cross plate outside upright connection of the upper clamping piece on the mounting plate
Hole, the outer outlet row and interior outlet row are vertically arranged on the outside of the mounting plate, and the inside and outside outlet row includes drawing
Portion, transition part and weld part, wherein the lead division is arranged in parallel with weld part, and the angle α of the transition part and lead division is
135 ° -150 °, the weld part is right-angled trapezium, and the waist of the right-angled trapezium is connect with the transition part, the outer outlet row
Lead division be equipped with first through hole and the second through-hole above first through hole, the lead division of the interior outlet row is equipped with
First through hole.
Further, the length of the lead division of the outer outlet row is greater than the length of the lead division of the interior outlet row.
Further, the first through hole position on the outer outlet row, interior outlet row and mounting plate corresponds.
Further, it is all provided between the outer outlet row and interior outlet row, between the interior outlet row and mounting plate useful
Make the insulator supported.
Further, the acute angles beta of the right-angled trapezium is 10 ° -15 °.
Further, the upper bottom length of the right-angled trapezium is 1-1.5cm.
Further, the position height of second through-hole is higher than the overhead height of the interior outlet row.
Further, the weld part is provided with welding groove along the bottom of the right-angled trapezium.
Further, the length of the weld part of the outer outlet row is the 2/3- of the length of the weld part of the interior outlet row
1 times.
Compared with the prior art, the utility model has the following beneficial effects: one-to-one first through hole is arranged, make in,
Coaxial line connects between outer outlet row and upper clamping piece, so as to shorten the lead division length of outer outlet row；Weld part is repacked into
Right-angled trapezium, when transformer load is run, electric current is aggregated into top by lower section smaller part position, the three of part under right-angled trapezium
Angular structure has given full play to the afflux characteristic of copper bar, and the structure of triangle mentions but also copper bar usage amount reduces 25% or so
High stock utilization, and since two right-angled trapeziums can be combined into a complete rectangle, i.e. every two outlet row can
It is obtained by cutting a whole copper bar, and leftover pieces will not be generated, the availability of material is made to have reached maximum；Simultaneously as
The electric current of the weld part end carrying of outer outlet row is almost 0, and the utility model is not under the premise of influencing outlet row current-carrying capacity
Further decrease outer outlet row weld part length, save the cost.
