摘要
PURPOSE: A temporary transformer and a method for replacing a transformer using the same are provided to uninterruptedly replace the transformer by using a hot line when a sing phase transformer or three phase pole transformer is damaged. CONSTITUTION: A high voltage connector(110) is connected to a high voltage line from a high voltage distribution line. A high voltage circuit breaker(120) breaks a high voltage current inputted from the high voltage distribution line. A transformer(130) transforms a high voltage current to a low voltage current. A forward and backward connection box(140) connects a neutral line and the low voltage line according to the connection state of the low voltage distribution line. A low voltage switch(150) switches a low voltage line. A low voltage connector(160) is connected to the low voltage line. An N line connector(170) is connected to a neutral line. The high voltage circuit breaker and the low voltage circuit breaker are positioned on the outside of the transformer and diagnoses and breaks an over load or fault current.
