Abstract

The utility model relates to a low-voltage wire-out structure for a transformer of an electric furnace, which comprises wire-out copper bars outside a transformer tank and wire leading copper bars in the transformer tank, wherein the wire leading copper bars are twice as many as the wire-out copper bars, such as 12 wire-out copper bars for 24 wire leading copper bars; each wire-out copper bar is connected with two wire leading copper bars via wire leading pieces. The utility model with simple structure effectively decreases the external dimension of the transformer, reduces the additional loss of the transformer and simultaneously provides convenience for users' external connecting lines for short networks.

Description

Furnace transformer low pressure outlet structure

Technical field

The utility model belongs to the transformer technology field, is specifically related to a kind of furnace transformer low pressure outlet structure.

Background technology

In the prior art, the inside and outside quantity of furnace transformer low-voltage copper bar is identical, be that lead-in wire copper bar quantity in the oil tank of transformer is identical with outlet copper bar quantity on the case lid, be generally 12 or 24, but no matter be to adopt 12 or 24, the defective that all has himself: when adopting 24 outlet copper bars (outer copper line), because this outlet copper bar all adopts two rows to be arranged in juxtaposition, at regular intervals between two copper bars, the width of its width sum when adopting 12 outlet copper bars, so the relative broad of transformer oil upper box part, copper bar is heavier relatively, and outside short net (being the copper bar that transformer outlet copper bar links to each other with consumer networks) line complexity; When adopting 12 outlet copper bars, lead-in wire copper bar (inner copper line) in the oil tank of transformer also is 12 simultaneously, sectional area when the sectional area ratio of this lead-in wire copper bar adopts 24 lead-in wire copper bars has at this moment increased one times, the relative broad of lead-in wire copper bar is thicker, therefore the width of oil tank of transformer is corresponding also will strengthen, required transformer oil and steel weight all can increase, and the transformer supplementary load loss increase simultaneously.

The utility model content

Technical problem to be solved in the utility model is the above-mentioned defective that exists at prior art, provide a kind of simple in structure, can effectively reduce transformer overall dimension, outside short net (copper bar that the transformer outer copper line links to each other with consumer networks) line furnace transformer low pressure outlet structure easily.

The technical scheme that solution the utility model technical problem is adopted is that this furnace transformer low pressure outlet structure comprises the outer outlet copper bar of oil tank of transformer, the lead-in wire copper bar in the oil tank of transformer, the lead-in wire copper bar is 2 times of outlet copper bar, as the outlet copper bar is 12, the lead-in wire copper bar is 24, and every outlet copper bar links to each other with two lead-in wire copper bars by lead wire.

In the utility model, lead-in wire copper bar in the oil tank of transformer adopts 24, both reduced the width of fuel tank bottom, reduce the use of transformer oil, can reduce the supplementary load loss of transformer again, and the outlet copper bar on the case lid adopts 12, both reduced the width on fuel tank top, reduce the use of transformer oil again, provide convenience for outside short net (copper bar that the transformer outer copper line links to each other with the consumer networks) line of user simultaneously.

Embodiment

As depicted in figs. 1 and 2, comprise the outlet copper bar 1 outside the oil tank of transformer 2, the lead-in wire copper bar 4 in the oil tank of transformer 2 in the present embodiment, wherein outlet copper bar 1 is 12, and lead-in wire copper bar 4 is that 2 times of outlet copper bar 1 are 24, and every outlet copper bar 1 links to each other with two lead-in wire copper bars 4 by lead wire 3.Fig. 1 is the left view of Fig. 2.

Claims

1, a kind of furnace transformer low pressure outlet structure, comprise the outer outlet copper bar (1) of oil tank of transformer (2), the lead-in wire copper bar (4) in the oil tank of transformer, the copper bar that it is characterized in that going between is 2 times of outlet copper bar, and every outlet copper bar links to each other with two lead-in wire copper bars by lead wire (3).

2, furnace transformer low pressure outlet structure according to claim 1 is characterized in that outlet copper bar (1) is 12, and lead-in wire copper bar (4) is 24.
