What to do if the voltage supply for combustible gases is insufficient
Thread Content
What to do if the voltage supplied to the combustible gas devices is insufficient? The voltage at the farthest device is only 13V, while the required voltage is 24V. What are some solutions?
How far is the farthest distance? What is the cross-sectional area of the power cable in square millimeters?
The power supply distance at the site needs to be clearly specified
Redraw the line. Asking such a simple question.
If the distance is too great, and there is a 220V power supply on site, then a switching power supply that converts the voltage to 24V should be used for power supply.
If the distance is really too great, add an explosion-proof box on site; inside this box, place a transmitter that converts the AC220V voltage to DC24V via a cable, so as to ensure that the voltage is sufficient
100 meters, 1.5 cable; the starting voltage is still sufficient, but after the workshop was modified and more probes were added, it became insufficient
If it were that simple as just laying out wires, would anyone come to ask? ? ? It’s an old workshop with a bus system; after modifications, many more sensors were added, and as a result the voltage became insufficient. The difficulty of laying cables isn’t too great; before, it was a bit tricky to navigate around the cable trays.
