Device for positioning and clamping leading-out wire of transformer foil coil

Abstract

The invention discloses a device for positioning and clamping a leading-out wire of a transformer foil coil. The device comprises a fixing plate, a positioning sliding plate and a bolt, wherein the positioning sliding plate is vertically fixed on the fixing plate by the bolt; a sliding slot is formed on the fixing plate; and the bolt passes through the sliding groove. The device has the advantages that: the height of the positioning sliding plate is adjusted in the sliding slot of the fixing plate so that the positioning sliding plate is concavely and convexly occluded with the leading-out wire; and the bolt is fastened so as to position and clamp the leading-out wire. The axial positioning of the leading-out wire is accurate and is not influenced by styles of a mold; a dry transformer or an oil immersed transformer can be applicable no matter the dry transformer or the oil immersed transformer is poured or not; and the operation is simple.

Description

technical field [0001] The invention relates to a positioning and clamping device, in particular to a device for positioning and clamping the lead-out wires of foil winding transformer coils. Background technique [0002] The fixing of the lead-out wires of the copper or aluminum bars of the transformer on the foil-wound coil is mostly determined by welding the concave baffle on the inner mold of the coil or installing other tooling components. This positioning device is only suitable for non-casting coils, and its application range is small; the positioning of the lead wires of copper bars or aluminum bars is not complete, and the axial direction of the inner mold is easy to move; the concave baffle plate welded on the inner mold is different due to the thickness of the lead wires. It is different, poor workmanship, which must be considered when designing product drawings, which affects the scalability of product drawings. At the same time, the welding concave table will al...

Problems solved by technology

This positioning device is only suitable for non-casting coils, and its application range is small; the positioning of the lead wires of copper or aluminum bars is not complete, and the axial direction of the inner mold is easy to move; the concave baffle plate welded on the inner mold is different due to the thickness of the lead wires. But different, the workmanship is poor, which must be considered when designing the product drawing, which affects the expansion of the product drawing. At the same time, the welding concave table will scratch the foil material, which will affect the safety and quality of the coil; the lead-out line is easy to deviate, and the product cannot meet the design requirements.
