Embodiment Construction

[0035] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0036] The specific embodiment of the coil wrapping tool of the present invention, as Figure 1 to Figure 18 As shown, in this embodiment, the coil wrapping tooling includes a base and a bracket arranged on the base, and the bracket is detachably connected with three support shafts 1 arranged in a horizontal star shape for supporting the coil. The horizontal star shape arrangement is The peripheral upper ends of the three support shafts are all located on the same horizontal plane. Through the support of each support shaft 1, the coil can be supported to a certain extent during the actual winding process, so that it is convenient for workers to wrap the coil, and the coil can rotate on the support shaft 1, effectively improving the winding efficiency. It is convenient for the welding of the secondary lead wire and the wrapping of the polyester film and ...

Abstract

The invention relates to a coil wrapping tool. The coil wrapping tool comprises a base and a support arranged on the base; the support is detachably connected with at least three supporting shafts which are arranged to form a structure in a horizontal star shape and are used for a supporting coil. In an actual wrapping process, the coil can be supported to a certain extent, so that a worker can wind the coil conveniently; the coil can rotate on the supporting shafts, so that the wrapping efficiency of the coil is effectively improved; manual processes such as the welding of a secondary outgoing line and the wrapping of a polyester film are facilitated, and labor intensity is low; and the supporting shafts are detachably connected with the support. With the above structure adopted, the coilwrapping tool has good overall structural stability and high strength in an actual operation process; and if the supporting shafts are bent and abraded, are break down or are subjected to other problems due to long-term pressing, the supporting shafts can be replaced at any time, and therefore, the maintenance cost of the tool is saved; and the structure of the tool is simple.

Description

technical field [0001] The invention relates to a coil wrapping tool. Background technique [0002] The coil is the most important and complex component in the transformer. It is formed by winding copper wire, iron core, polyester film, etc. The performance of the coil level voltage determines the capacity of the transformer itself, and the accuracy level determines the coil. The excitation performance and the inner and outer diameter dimensions and height dimensions of the coil. Coils with a voltage level of 300kV and above have large inner and outer diameters and are heavy in weight. The weight of the protective coil and TPY coil is particularly prominent, which can reach about one ton. After passing the test, the coil needs to be wrapped with outer insulation. When the outer insulation is wrapped, it can only be placed on the ring winding machine. There are many difficulties in manual processes such as the alignment of the coil, the wrapping of the polyester film, and t...
