No fuse in the alternator. If there were, then there would be a procedure for replacing it.
There are diodes in the alternator, as Fimum says. Lose a diode, and you'll get low output voltage and an ALT dash light.
Can PS fluid hurt an alternator? Could. I can see it contaminating the brushes and causing a carbon build-up. It's basically oil, and from my reading it doesn't attack insulation, and it isn't a conductor.
I'd want to know why the alternators are being rebuilt. Usually it's the VR that dies. The alternator itself is just a coil of wire on a shaft (armature) spinning inside another coil of wire. Coil of wire, bearings, coil of wire. The only electronics other than the VR is the diode block, and if you really push it, the commutator where the brushes ride. I suspect a lot of alternators get replaced because it gets the shop fewer call-backs than replacing the cheaper VR.
When I find a shop that demonstrates incompentence, I leave before they have a chance to demonstrate Serial incompentence.
