Ultra high voltage tank cage insertion mould

Abstract

The invention discloses an ultra high voltage tank cage insertion mould, and mainly relates to the technical field of power transformer equipment. The mould comprises a central shaft, central guidingis arranged in the middle of the central shaft, sliding assemblies are respectively arranged on both sides of the central guiding and the central shaft, umbrella-shaped supports are arranged at four-corner positions of the sliding assemblies, the umbrella-shaped supports are rotatably connected to the sliding assemblies, the other ends of the umbrella-shaped supports are disposed on tank cage supports, the umbrella-shaped supports and the tank cage supports are connected through hinges, the two ends of the tank cage supports are connected with end guiding, a driving mechanism is disposed on one side of one end guiding, one side of the driving mechanism and one side of the other end guiding are respectively provided support assemblies, the support assembles are connected by cage supports, the outer surfaces of the cage supports are fixedly provided with tank cage rod members, grooves are formed in the upper surfaces of the tank cage members for installing outer round supporting strip blocks and outer round supporting strips, and the problem of waste of materials and working hours during winding and the problem of support of neutral internal supporting strips are effectively solved.

Description

technical field [0001] The invention mainly relates to the technical field of power transformer equipment, in particular to an UHV slot cage plug-in die. Background technique [0002] There has been no good solution to the winding problem of the high-voltage coil of the UHV power transformer without the inner paper tube structure. Generally, the size of the winding mold is reduced theoretically, and a false paper tube and insulating stays are attached during winding. way to solve it. Such a solution not only leads to the material waste of expensive inner paper tubes and insulating stays, but also brings extra work to the operator for false paper tube outer circle grading and sticking stays (one complete grading, sticking stays It takes about 8-10 hours), resulting in low efficiency of the coil winding process. Moreover, the number of inner stays of the high-voltage coil of the UHV power transformer is relatively large, and in most cases it cannot correspond to the number o...
