The basic idea of electrical control cabinet design is a kind of logical thinking. As long as it conforms to the logic control law, it can ensure electrical safety and meet the requirements of the production process, which can be said to be a good design.

The general assembly drawing and wiring diagram of the electrical control cabinet (which can be separated or combined as required) are the basis for subdivision design and coordination of various parts into a complete system. The overall design shall make the whole electrical control system centralized and compact. At the same time, if space permits, place heating parts and electrical parts in places with high noise and vibration to keep them as far away or isolated from other parts as possible; For large multi station equipment, the convenience of operation in two places shall also be considered; The main power switch and emergency stop control switch of the control cabinet shall be placed in a convenient and obvious position.

However, in order to meet the manufacturing and use requirements of electrical control equipment, reasonable electrical control process design is needed. These designs include the structural design of the electrical control cabinet, the overall configuration drawing of the electrical control cabinet, the overall wiring diagram design, and the electrical assembly drawing and wiring diagram design of each part. At the same time, there is a part of the component catalog, the number of inlet and outlet conductors, 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 divide each component into several components according to the electrical complexity of the control cabinet, Then classify the incoming and outgoing line 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 expressed in the form of general assembly drawing and general wiring diagram of electrical system. It shall reflect the position of the main components of each part, the wiring relationship of each part, the wiring method and the trunking, pipeline, etc.
