The utility model relates to an intelligent voltage transformer which is an indispensable part in electrical equipment, and belongs to the technical field of the electrical equipment. The intelligent voltage transformer is provided with a signal detecting unit, a signal processing unit and an execution unit. When the signal detecting unit detects short circuit signals, the execution unit cuts off a short circuit source immediately to guarantee the transformer to be not damaged, when short circuit faults are removed, the signal detecting unit determines that a short circuit state does not exist, the execution unit unlocks immediately, and the transformer can be restored to work normally. The intelligent voltage transformer breaks the statement that a voltage transformer explodes or is burnt necessarily in a second short circuit said in an existing textbook, when a short circuit happens to the secondary voltage of the voltage transformer, damage can be effectively avoided, great significance is achieved to the
