Took a while to actually trip and extinguish the arc. But that's not an explosion, just a bigarse electric arc. That's doing more or less what it's supposed to do in the event of a failure.
If that's at a power station, that's a lot of energy going through that, vapourising and melting the metal conductors. (Busbar or transformer possibly).
