Equipment for automatically manufacturing special pancake winding for power distribution network transformer

Abstract

The invention relates to equipment for automatically manufacturing a special pancake winding for a power distribution network transformer. The equipment comprises an installation ring and an insulating cylinder, wherein a wire bar is wound at the lower end of the insulating cylinder; a plurality of winding manufacturing devices are uniformly arranged at the lower end face of the installation ring, each winding manufacturing device comprises a fixed plate welded to the lower end face of the installation ring, three lifting driving mechanisms are arranged at the lower end face of each fixed plate respectively, an installation rack is arranged at the lower ends of two lifting mechanisms positioned on the left side of each fixed plate, a positive pancake guiding mechanism is arranged at the left end of each installation rack, the positive pancake guiding mechanisms can play a role of automatically placing an oil passage cushion block, a negative pancake block discharging mechanism is arranged at the middle part of each installation rack, the negative pancake block discharging mechanisms can play the roles of automatically taking negative pancake layers and quickly taking out negative pancake cushion blocks, a negative pancake guiding mechanism is arranged on the lower side of the right end of each installation rack, and the negative pancake guiding mechanisms play a role of automatically telescoping and placing the negative pancake cushion blocks. According to the equipment, full-automatic processing performance of the pancake winding can be realized, and manual operation is not needed.

Description

technical field [0001] The invention relates to the technical field of transformer winding processing, in particular to an automatic manufacturing equipment for pie-shaped windings dedicated to distribution network transformers. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. It has functions such as voltage conversion, current conversion, impedance conversion, isolation, and voltage stabilization. Therefore, it is widely used in distribution network substations. The transformer is composed of windings and iron cores. The core is mainly composed of the lower clamp, the lower iron, the core column, the upper iron and the upper clamp. The winding can be a layer winding or a cake winding. Among them, the cake winding should be the most widely used in substations and distribution networks. Transformers, so the demand for pie-shaped windings is very large. The existing manufacturing process o...
