We know that the Inductive Reactance (XL) is zero on dc. Since frequency is zero.
In case of connecting transformer's coil to a dc supply a short-circuit will take place immediately and a heavy current will pass capable to burn and damage the coil (in this case the coil resistance is negligible or almost zero).
