Winding device for transformer core

Abstract

The invention discloses a winding device for a transformer core, which comprises a shell, wherein heat dissipation holes are formed in the upper end of the shell, the upper end of the shell is sleevedwith a threaded rod through a thread, the outer side of the threaded rod is sleeved with a pressing plate in a sliding mode, a square hole is formed in the threaded rod, a square rod is connected into the square hole in a sliding manner, a cross rod is welded at the upper end of the square rod, a supporting sleeve is welded to the upper end of the pressing plate, a plurality of clamping grooves are formed in the upper end of the supporting sleeve, a transverse rod is slidably connected into the clamping grooves, the plurality of clamping grooves are evenly distributed in the upper end of thesupporting sleeve, four pressing rods are welded to the lower end of the pressing plate, the four pressing rods are evenly distributed at the lower end of the pressing plate, and the outer sides of the pressing rods are slidably connected with first springs in a sleeving mode. The invention relates to a winding device for a transformer core. The winding device has the advantages that the core isstably installed and not prone to loosening, the winding insulation effect is good, and noise generated by device vibration is low.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a winding device for transformer iron cores. Background technique [0002] The iron core is the main magnetic circuit part of the transformer. It is usually made of stacked hot-rolled or cold-rolled silicon steel sheets with high silicon content and coated with insulating paint. The iron core and the coil wound on it form a complete electromagnetic induction system. The transmission power of the power transformer depends on the material and cross-sectional area of ​​the iron core. The winding refers to a group of turns that constitute an electrical circuit corresponding to a certain voltage value marked on the transformer. The number of turns of each secondary winding is different, and its terminal voltage is also different, so the multi-winding transformer can supply power to several electrical equipment with different voltages. The most commonly used in power systems is...

AI Technical Summary

Problems solved by technology

However, there are some problems in the winding device currently used for transformer cores: 1. The iron core is not stable enough during installation, and the vibration during operation causes the installation of the iron core to loosen; 2. When the winding is working, the winding insulation is poor, and the current of the winding wire is too large. Breakdown; 3. When working, the device vibrates and generates noise, resulting in noise pollution
