Regarding the issue of professional division of labor
Thread Content
Are both AC220V and AV380V supplied by electricity? Or is the electrical only responsible for the AV380V power supply of the instrument? For projects that I have been exposed to before (at that time in other units), the electrical major AC220V was also provided. I don’t know how the instrument power supply is done in the design institute where you are or where you are in contact with.
Here we supply AC380V power from the electrical supply to the instrument electronics room (cabinet room), and the AC220V power supply for the instrument is distributed and powered by the AC380V power supply.
Generally, the total power supply (380 or 220) is electrically supplied to the instrument cabinet, and the rest is provided by the instrument itself.
Maybe our division of labor is different. Anything above 220 volts is done electrically, and anything below 220 volts is done electrically~!
Here, everything with AC220V and above is made electrically, and only the instruments with DC24V are made by ourselves.
From the electrical to the instrument cabinet, how to distribute it afterwards is a matter for the instrument professional.
Life is still comfortable in 4L and 5L: loveliness:
HG-T 20636.4-1998 There are clear regulations on the design division of labor between automatic control majors and electrical majors, but many companies have their own divisions. The specific division depends on which major is stronger, electrical or instrumentation!
