Auxiliary equipment for detecting compactness of transformer iron core

Abstract

The invention belongs to the field of transformers, and particularly relates to an auxiliary equipment for detecting the compactness of a transformer iron core, which comprises a base, the outer surface of the right side of the base is rotationally connected with a detection mechanism, and a display mechanism is arranged on the left side of the detection mechanism. According to the auxiliary equipment for detecting the compactness of the transformer iron core, by arranging the bottom plate and the top plate, when the equipment is used, the iron core of the transformer is placed in a gap between the top plate and the bottom plate, and the iron core of the transformer is mostly an EI iron core and can be exactly clamped in the EI-shaped clamping grooves in the bottom plate and the top plate, so that in the process of gradually stacking the iron core upwards, the base plate moves along with the iron cores, it is guaranteed that the iron cores cannot incline or deviate in the vertical direction, a set of iron cores are perpendicular to the upper surface of the base all the time, errors during detection are reduced, and the problems that when traditional clamping equipment fixes the iron cores, loose iron cores are prone to skew and deviate, and measurement errors are increased are solved.

Description

technical field [0001] The invention belongs to the field of transformers, in particular to an auxiliary device for detecting the tightness of 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. [0003] In order to increase the power transmission efficiency and cross-sectional area, the iron cores are usually stacked in sheets. Since the sheet iron cores lack external fixing parts, after long-term use, the material will be deformed by heat, and the tightness between the iron cores will decrease, resulting in gaps. The gaps are small, and it is generally difficult to...
