Description
Technical field
The present invention relates to a kind of transformer lead structure, relate in particular to a kind of low-voltage y connecting lead structure of dry-type transformer with three-dimensional rolled iron core.
Background technology
The low-voltage y connecting lead structure of tradition three-phase transformer is: with the end leads of three-phase low-voltage coil with busbar be linked together; Head end lead-in wire is fixed on the upper clamping piece by the low voltage terminal daughter board through transition busbar (or transition lead-in wire), thisly connects the transformer that method is suitable for the three-phase coil floor plan.Because energy-efficient three-dimensional rolled iron core transformer layout is different with traditional transformer; The three-phase low-voltage coil can't whole outlets in the same side; And transformer low voltage terminals and low-tension switch cabinet require the transformer low voltage terminals in the same side usually, and therefore traditional low-voltage y connecting lead structure is not suitable for the particularly energy-efficient dry-type transformer with three-dimensional rolled iron core of energy-efficient three-dimensional rolled iron core transformer.
Summary of the invention
The objective of the invention is to: overcome conventional y and connect the method pin configuration and be used for the particularly deficiency on the dry-type transformer with three-dimensional rolled iron core of the tangible three-dimensional rolled iron core transformer of materials saving, a kind of low-voltage y connecting lead structure of simple in structure, safe and practical, elegant in appearance, three-dimensional rolled iron core transformer that the high and low pressure side Wiring area separates, is convenient to terminal block fully is provided.
The present invention realizes through following scheme: b phase low-voltage coil head end lead-in wire links to the transition busbar; Again with connect Volleyball Association and connect; Final and b phase connection terminal board connects; B phase connection terminal board and c phase connection terminal board, a phase connection terminal board exist together and are fixed on the transformer upper clamping piece behind the same side, and the terminal busbar of low-voltage coil directly connects with transition 0 busbar, connects with 0 terminal board again.
Transition busbar according to the invention with connect the connecting all through contact row of row, transition 0 busbar and 0 terminal board with fastening standard component connection.
Transition busbar according to the invention, connection row, transition 0 busbar, 0 terminal board all parallel layout with transformer volume iron yoke unshakable in one's determination.
The mode of b phase low-voltage coil head end according to the invention lead-in wire through fastening standard component or welding and b rebound mutually are attached to the transition busbar, and low-voltage coil end busbar directly welds or connects with transition 0 busbar through fastening standard component.
The present invention is simple in structure, safe and practical, elegant in appearance, the high and low pressure side Wiring area separates, is convenient to terminal block fully, is suitable for the particularly energy-efficient dry-type transformer with three-dimensional rolled iron core of energy-efficient three-dimensional rolled iron core transformer.

Embodiment
Below in conjunction with embodiment and contrast accompanying drawing the present invention is elaborated.
Present embodiment is not for will causing a, c phase the same side in the b of the same side phase low voltage terminal.Referring to Fig. 2-4; The b phase low-voltage coil head end of present embodiment lead-in wire through fastening standard component mode and b mutually rebound 1 be attached to transition busbar 2; Arrange 4 connections by contact row 3 with connecting again; Final and 5 connections of b phase connection terminal board, existing together with c phase connection terminal board 6, a phase connection terminal board 7 is fixed on the transformer upper clamping piece behind the same side.The terminal busbar of b phase low-voltage coil connects with transition 0 busbar 8 through fastening standard component 10, is connected with 0 terminal board 9 by the row of contact 3 again.Transition busbar 2, connection row 4, transition 0 busbar 8,0 terminal board 9 all parallel layout with transformer volume iron yoke unshakable in one's determination.For making things convenient for the first end leads of low-voltage coil firm with the welding of transition busbar, transition busbar 2 with connects row 4, transition 0 busbar 8 connects all through fastening standard component 10 connections of the row's of contact 3 usefulness with 0 terminal board 9.
The principle of the invention also comprises the situation that a or c phase low voltage terminal is caused other two phase the same sides.
