Description

Tool for measuring distance between iron core columns

Technical Field

The invention belongs to the technical field of transformer production, and particularly relates to a tool for measuring the distance between iron core columns.

Background

The distance between the iron core columns refers to the distance between the iron core columns and the iron core columns or the distance between the iron core columns and the side yoke at the same step, and for the iron core without the upper yoke, the value of the distance directly influences the quality of iron insertion of the upper yoke iron. Therefore, the overall measurement of the sizes of all the iron core frames is carried out before the iron cores are sleeved. One important point of this measurement is that the measuring tool should be kept in a horizontal position during the measurement. Currently, the commonly used measuring tools such as the inside box ruler need to be held by an operator to be horizontal, so that the requirement on the operator is high, and the level of the measuring tool is still difficult to ensure.
