Since the power came back after about half a minute, I would say no fuse
blew on the line. Instead there may have been a major drain of power such as
mentioned below with a branch hanging onto the line but not creating a dead
short that would have blown the line fuse. With a major draining of power,
that left you enough to make the lamps glow, possibly the wind blew the
branch back off the lines allowing full power to be restored. Possibly, if
the branch stayed on the line much longer the fuse would have popped, and
you would be in the dark until a power line worker replaced the fuse.

Not a replaceable fuse, no, but a breaker may well have opened (and
probably did) to give the line a chance to clear of whatever was the
problem.

When it reset, sounds like a temporary sag which isn't too uncommon on
long lines, particularly if there might be a fairly sizable load
somewhere off the particular affected line. High inrush currents of all
those A/C's, fridges, etc., plus any other large single-point loads if
any all add up to quite a chunk...add that to a possibility of a partial
drain not quite cleared yet and not at all uncommon for it to take 30
seconds or so to recover...happens to us on the rural lines quite often.
