What knowledge do you need to draw an electrical secondary diagram? First of all, the high and low voltage electrical principles must be clear, which is necessary, not to mention.

Others are as follows:

1. Drawing standards, mainly including national standards, IEC standards, German DIN standards and Russian GHOST standards. German DIN standard is recommended, which is very scientific, reasonable and rigorous. He is used by major international companies to paint. However, the gap between the habit and the national standard is too big, and domestic elderly engineers are not welcome.

2. The drawing standard is mainly the drawing of electrical components. Marking method of electrical component name, cross-page reference method of components, terminal number, cable statistics, etc.

3. Understand the calculation of current carrying capacity of cables, copper bars and conductors, and mark the diameters and models of cables and copper bars on the primary diagram or power supply system diagram. But these are all on the table.

4. If you make a cabinet, you can think clearly about the size of components and cabinet space, and arrange components and wiring reasonably.

That's basically it. Drawing is easy, and everyone has a way to draw. But if you want to draw well, you must follow certain standards. I think it's best to refer to DIN standard. And DIN standards have professional drawing software. Wish you success! PM me if something happens!
