Abstract

The invention discloses an adjustable winding die for a long circular coil of a distribution transformer. The adjustable winding die comprises a square shaft sleeve, a plurality of long shaft adjusting devices are symmetrically arranged on the upper surface and the lower surface of the square shaft sleeve, the top ends of the long shaft adjusting devices are provided with a support plate, the support plate is provided with a hydraulic cylinder, and a plurality of hydraulic supporting rods are arranged in the axial direction of the hydraulic cylinder in a semicircular mode. Through cooperativeconnection of adjusting nuts and the two reverse screws, the adjustment of the long circular coil in the long shaft direction is achieved; the hydraulic cylinder is changed to the semicircular hydraulic cylinder by adopting the hydraulic lifting principle, and the plurality of telescopic hydraulic support rods are axially arranged on the semicircular hydraulic cylinder, so that the size of the circular arc of the long circular coil is adjusted. The novel adjustable winding die is ingenious in structural design, simple and practical and easy to operate, saves raw materials for manufacturing, saves storage space, reduces the production cost, and improves the working efficiency.

Description

technical field [0001] The invention relates to the technical field of winding molds, in particular to an adjustable winding mold for an oblong coil of a distribution transformer. Background technique [0002] The coil is the heart of the transformer. When the transformer is running, when the line fails or the lightning strikes the atmospheric overvoltage and the action of the circuit breaker on the line generates an operating shock wave, the coil will withstand an instantaneous overvoltage much higher than the rated working voltage. The long circular coil is also known as the track-shaped coil. As the name suggests, the circular coil is divided into two halves, and a straight line is added in the middle, which is similar to the shape of the track in the sports field, hence the name. Compared with the traditional circular coil transformer, the center distance of the transformer will be reduced correspondingly after the long circular coil is adopted, and the window width of t...
