Description
?
Technical field
The present invention relates to a kind of dry-type transformer, specifically a kind of novel solid coil iron core dry-type transformer low-voltage lead syndeton.
Background technology
Three-dimensional coil iron core dry-type transformer is as the new-type transformer that occurs on the recent market, because its pair energy-saving advantages becomes a kind of trend of distribution transformer development.But, connect difficulty because its particular structure causes the low-voltage coil lead-out wire not on same plane.The low-voltage lead connected mode that present three-dimensional coil iron core dry-type transformer adopts; Like Fig. 1-1 to shown in Fig. 1-3; With the low-voltage coil c phase z end row of drawing 11, a phase x end row of drawing 13 and b mutually y hold the row of drawing 16 to draw to be connected on the excessive row 15, tie point is on the central point M of transformer upper surface.The b phase b end row of drawing 12 strides across the low-pressure side that the transformer upper surface is connected to transformer, and distance is longer, for satisfying the requirement of low-voltage direct resistance unbalance factor, must reduce the resistance that this section connects row, has so just strengthened this section connection row's sectional area.
The shortcoming of the present this connected mode of this kind is:
1, used copper bar lead-in wire kind is more, complex connection, and some copper bar lead-in wires are held the row of drawing 12 like the b phase y end row of drawing 16, b phase b, need carry out welding operation, and production efficiency is low.
2, strengthened low-voltage coil b phase b and held the sectional area of the row of drawing 12, the b phase y end row of drawing 16, and two terminal leads layouts of each phase of low pressure complications institute is longer through distance, has so just increased the copper bar use amount, production cost is higher.
3, the low-voltage lead connection is comparatively in disorder, and outward appearance is not good.
Summary of the invention
In order to overcome the problem that prior art exists; The purpose of this invention is to provide a kind of three-dimensional coil iron core dry-type transformer low-voltage lead syndeton; This structure has shortened to connect drains linear distance; Need not to increase the copper bar cross-sectional area and just reach the requirement of GB, reduced the copper bar use amount, reduced production cost about low resistance balancedunbalanced rate; It all is that bolt connects that each lead-in wire connects, and need not welding, has improved efficiency; It is rationally distributed to go between, compact conformation, good looking appearance.
The objective of the invention is to realize through following technical scheme:
A kind of three-dimensional coil iron core dry-type transformer low-voltage lead syndeton is characterized in that: in this structure, a phase x in low-voltage coil end and b y end mutually connect row's connection by ab; C phase z in low-voltage coil end and b y end mutually connect row's connection by cb; B in the low-voltage coil two outlet terminal b ends mutually is arranged in the step down side right opposite with the y end, and low pressure b phase b holds the row of drawing to stride across the transformer upper surface to be drawn out to step down side; 0 terminal board, one end of lifting one's head is drawn out to low-pressure side as transformer low voltage 0 terminal, and the other end connects row with ab and connects at y end place mutually near b.
Among the present invention, low pressure b phase y end is drawn out to the folder top with the row of drawing, and is connected row again with ab and is connected row's connection with cb; Ab connects row and is connected all employing setting cabling modes of row with cb, and left-right symmetric is separately positioned on the b phase b end row of drawing both sides.0 terminal board of lifting one's head also adopts the mode of erectting cabling.
Advantage of the present invention is following:
1, a phase x end row of drawing, c phase z end row of drawing and the b connection row setting straight line cabling connection between the y end row of drawing mutually, the shortening distance of passing through has reduced the copper bar use amount than the connection of original complications, has reduced production cost.
2, connected mode of the present invention makes that the wire length of low-voltage coil a phase, b phase, c phase is close, need not to increase the copper bar cross-sectional area and just can satisfy the requirement of GB about low-voltage direct resistance unbalance factor.The b end of b phase, two more original connected modes of terminal lead copper bar weight of y end have saved 1/3, have reduced production cost.
3, low-voltage lead kind and tie point reduce, and it all is that bolt connects that each lead-in wire connects, and need not welding, has improved efficiency.
4, lead-in wire is rationally distributed, the low-voltage lead left-right symmetric of a phase, c phase, and compact conformation has solved the not good problem of presentation quality.
