I'm looking at a schematics of a power system, and encountered some schematics I find quite strange.
As you can see, the schematic contains a lot of bent lines. I have two hypothesis:
- It indicates jumpers, see this question.
- It indicates fuses
As you can see, the horizontal line in the bottom is labeled "30m Cross Over Jumper Spectron 10". This of course, strengthens hypothesis 1. I think it also makes sense, seeing there are connectors you can connect/disconnect. However, I don't see why you would need three of them for just one single branch. Also, the system is subsea, I don't know if you can use jumpers the same way you do in "normal" systems.
I think it looks similar to common symbols for fuses, but again, I don't see why there should be so many. (And fuses on the bottom of the ocean doesn't seem like a particularly good idea).
- The distances are small (from the red arrow and down, the schematic has been updated. Above the red arrow, the cables may be long). The transformer is very close to the load (compressors).
- The horizontal cable at the bottom goes to an identical parallel setup (100kVA transformer, 36.5 kW load etc.).
- The entire system is subsea.
- The power umbilical is several km
Here's a more complete schematic.
Does anyone know what the symbol means?
