However, in order to meet the manufacturing and use requirements of electrical control equipment, a reasonable electrical control process design is required. These designs include the structural design of the electrical control cabinet, the overall configuration diagram of the electrical control cabinet, the overall wiring diagram design and the design of the electrical assembly diagram and wiring diagram of each part. At the same time, there is a part of the component catalog, the number of inlet and outlet wires, and the list of main materials.


The overall configuration design task of the electrical control cabinet is to first divide the control system into several components (these components are called components) according to the working principle and control requirements of the electrical schematic diagram, and then according to the complexity of the electrical control cabinet, the electrical control cabinet manufacturer Divide each component into several components, and then classify the incoming and outgoing numbers of each part according to the wiring relationship of the electrical schematic diagram, and adjust the connection between them. The overall configuration design is represented in the form of the general assembly diagram and the general wiring diagram of the electrical system. The diagram shall reflect the location of the main components of each part and the wiring relationship, wiring method, trunking, pipeline, etc. of each part in the form of schematic diagram.

The assembly diagram and wiring diagram of the electrical control cabinet (which can be separated or combined as required) are the basis for the design and coordination of the various parts into a complete system. The overall design shall be such that the entire electrical control system is centralized and compact. At the same time, when space permits, place the heating components and electrical components in places with large noise and vibration, so that they are as far away from or isolated from other components as possible; for large multi-station equipment, consideration should also be given to the convenience of operation in two places; the main power switch and emergency stop control switch of the control cabinet should be placed in a convenient and obvious position.


Whether the overall configuration design is reasonable is related to the manufacturing and assembly quality of the electrical control system, and will also affect the performance of the electrical control system and its reliability, convenience, and the quality of operation, debugging and maintenance.
