Drawing method of main busbar connection diagram between dry-type distribution transformer and low-voltage switchgear

Abstract

The method for drawing the main busbar connection diagram between the dry-type distribution transformer and the low-voltage switchgear of the present invention relates to the conductive connection of the transformer. The drawing method determines the coordinate values ​​of the relevant parameters in the established XY coordinate system; the drawing method is written in the Visual C++ language. In the human-computer interaction interface, the data required for drawing is input into the computer. Determine the position and shape of each connected copper bar according to the input outlet method, the phase sequence of the input copper bar of the low-voltage switchgear and the coordinate value of each phase of the input copper bar of the low-voltage switchgear, and draw each connected copper bar. According to the coordinate values ​​of the low-voltage side copper bars of each phase of the dry-type distribution transformer, determine the position and shape of each phase outgoing copper bar of the dry-type distribution transformer, and draw the outgoing copper bars of each phase of the dry-type distribution transformer. The drawing method of the invention can significantly shorten the design cycle of the main busbar connection diagram between the dry-type distribution transformer and the low-voltage switchgear, improve the quality of the drawings, and meet the design requirements.

Description

technical field [0001] The technical solution of the present invention relates to the conductive connection of transformers, in particular to a method for drawing a main busbar connection diagram between a dry-type distribution transformer and a low-voltage switchgear. Background technique [0002] The dry-type distribution transformer is placed in the cabinet during application, and its high-voltage side is connected to the high-voltage switch through cables, and its low-voltage side copper bar is connected to the input copper bar of the low-voltage switch cabinet. Since the relative positions of the dry-type distribution transformer and the low-voltage switchgear vary greatly, the positions of the copper bars on the low-voltage side of the dry-type distribution transformer and the input copper bars of the low-voltage switchgear have many situations. Almost every dry-type distribution transformer A set of main bus connection diagrams must be redrawn. At present, the main b...
