Vertical winding die of stereoscopic reeled iron core with voltage of 110kV and more

Abstract

The invention discloses a vertical winding die of a stereoscopic reeled iron core with voltage of 110kV and more. The vertical winding die comprises an upper die, a lower die and a winding die body, wherein the upper die comprises an upper die inner ring and an upper die outer ring, and the upper die outer ring rotationally sleeves the periphery of the upper die inner ring; the lower die comprises a gear die turn plate, a gear ring and a gear die tray, and the gear ring rotationally sleeves the periphery of the gear die tray; the winding die body is of a cylindrical structure, divided into at least three parts along the axial direction, and provided with clamping pins at the bottom; the upper die inner ring sleeves the upper end of the winding die for locking and fixing the shape of the same; the gear die turn plate is provided with a clamping groove, the winding die body is inserted into the clamping groove through the clamping pins to be locked and connected to the lower die; the upper die, the lower die and the winding die are respectively of a detachable structure, thus being convenient to be combined with the closed stereoscopic reeled iron core to wind a coil after disassembly; the vertical winding die is simple in structure, convenient to operate and wide in applicability, can ensure quality and rapid winding of the coil, solves the problem of cumbersome process steps in the winding of stereoscopic reeled iron core, and is greatly reduced in production cost.

Description

technical field [0001] The invention relates to a transformer coil winding die, in particular to a vertical winding die for a three-dimensional wound iron core with a voltage of 110kV and above. Background technique [0002] The traditional transformer vertical winding machine mainly uses the faceplate rotating system to directly wind the coil, and the faceplate and the winding die are fixed together for rotation. Due to the three-dimensional wound core power transformer, the iron core is a closed design, which needs to be integrated with the coil, so it cannot be wound by a traditional three-dimensional winding machine. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a vertical winding die for a three-dimensional wound core with a voltage of 110kV and above, which solves the problem of coil winding for a three-dimensional wound core with a voltage level of 110kV and above, and can perform closed-end three-...
