A Secondary Wiring Method of Switchgear Based on Contour Outward Expansion

Abstract

The invention discloses a switch cabinet secondary connection method based on external expansion of contour lines, and belongs to the field of computer assisted design. The switch cabinet secondary connection method based on external expansion of the contour lines comprises the following steps: (1) generating convex contour lines according to components and a cabinet structure, and extending and cutting out the contour lines to generate a secondary connection main path; (2) taking the secondary connection main path as a basis, and constructing a local wiring network which is connected to the secondary connection main path so as to form a secondary complete connection grid; and (3) searching the shortest secondary connection path in the generated complete connection grid according to a secondary connection heuristic evaluation rule. A secondary connection component is used as a main body, an available connection path is rapidly constructed through external expansion of the contour lines, meanwhile, the cabinet body structure is considered, on the premise of solving the shortest connection path, bending of connection and crowding of a line are reduced as much as possible, and thus, the service life of a switch cabinet is ensured.

Description

technical field [0001] The invention belongs to the field of computer-aided design, and in particular relates to a secondary wiring method of a switch cabinet based on outline expansion. Background technique [0002] Secondary wiring is an important work in switchgear manufacturing. Common secondary components in switch cabinets include control switches, fuses and relays. Secondary wiring can be simply described as using cables to connect various components. Specifically, the work content of the secondary wiring mainly includes: First, according to the components and wiring information provided in the electrical schematic diagram, the measurement line is carried out on the physical cabinet with the components installed. Secondly, count and input the wire automatic processing equipment to manufacture and cut the wire. Subsequently, the manufactured wires are completed on the physical cabinet body for wiring. Finally, after repeated checks and checks, to ensure that the wi...

Problems solved by technology

However, this three-dimensional wiring method can only consider the overall space of the switchgear as a wiring space, and cannot make full use of the layout of secondary wiring related components and the structure of the cabinet for intelligent wiring. The number of bending times of wiring and the density of wiring cannot effectively deal with the actual secondary wiring problem
