Graphical complete electrical distribution cabinet principle

There is a principle about the package that is shared with everyone:
Realize the first function, reliable and durable second place, help to maintain the third place, easy to process the fourth place, beautiful and neat fifth place
The first three points are the most important, and the last two points sometimes need to make some compromises. After all, everything is subject to cost factors.
Based on this principle, I am here to say that I feel that I have done a significant lack of it. I don’t necessarily say that there is no problem, it may be missing, or it may not be important, of course Ok, no problem.

Figure 1

Figure 1 The problem of the complete set of cabinets is unreasonable, unsightly and unsafe. The space in the upper and lower spaces of the incoming switch is too cramped. There is no spacer between the air inlet and outlet phases and the cable. There is a large stress between the terminals. It is recommended to use the copper row structure to enter the line and open the door handle to operate.

The layout of 131313 is not very reasonable. The strong electricity surrounds the weak current. The grounding measures are not good, and the interference is more difficult to solve.

Figure 2: Problems with the complete set of electrical cabinets
1. The problem with Figure 10, 11, 12 is that the wiring is messy.
2. It feels that the overall wire diameter is small, especially the ground wire diameter.
3. The main incoming line is not open and no auxiliary contact is input to the CU, nor is the main power supply controlled by the CU controlling the main contactor.
4. The shield of the motor and encoder wires is not grounded repeatedly.

Summary: 1, the good cabinet is designed, there are specifications, there are designs, to be clearly and correctly implemented on the drawings, in order to allow the complete set of processing to make, the design engineer should not complain that the following sets of processing are not done, and It is first to examine whether you have designed the drawings.
2. The design engineer should do a good job of communication with the complete set of processing, especially the new drawings. It is best to visit the site in the first place to see if the actual layout and design are consistent, listen to the suggestions of the on-site workers, and avoid closed doors. Sometimes the drawings look pleasing to the eye, but the layout is unreasonable, and even the difficulty of processing the wiring. At this time, the suggestions of the experienced workers' masters are very valuable. It is necessary to promptly listen to suggestions and make changes as soon as possible. Remember Don't be tempted to let go and let go, don't be willing to die and not repent.
3. It is necessary to form a set of processing technology and specifications suitable for oneself, to develop a good habit of complete processing according to the drawings, to distinguish the authority and responsibility, the design engineer is responsible for the drawings, and the complete processing party is not responsible for the drawings.
4. Strictly adopt the factory acceptance system, strictly check and accept according to the drawings, and rework with the figure.
5, each time summed up the experience and lessons in the design and complete processing, leaving a summary of the minutes for the next similar design for reference and improvement.
6. Even in the process of processing complete sets, the design engineer should have more conditions in the workshop and care about the design of his own.
The complete set of electrical cabinets is communicated with the on-site complete processing party:
1 Master the progress of production and processing;
2 timely discover and solve the problems encountered in the actual production or some of the details of the processing (especially when the trunking cover has not been covered);
3 It is necessary to take some photos of some electrical cabinets in different processing stages, leaving pictures and materials for reference analysis and improvement on subsequent designs.
