The invention discloses an intelligent component cabinet and a monitoring method for an intelligent transformer. Intelligent electronic equipment is installed in the intelligent component cabinet and comprises a measuring IED, a cooler controlling IED, a load voltage adjusting IED, an in-oil dissolved gas and micro water monitoring IED, a partial discharging monitoring IED, a light winding temperature detecting IED, a reactor magnetic leakage and partial overheating monitoring IED, a reactor iron core cake vibration monitoring IED, a combining unit, a non electricity protecting IED and a main IED. Sensors adopted by the IED acquire transformer operation, control and reliable state information and combines unit current signals, and an intelligent component processes the acquired data, forms integral intelligent result information and transmits to a station control layer network by a communication protocol DL / T860; information support is provided to transformer monitoring and intelligent control, power grid operation optimization and transformer maintenance strategy optimization, and the electromagnetic interference resistance and high voltage resistance of electronic products in intelligent component cabinet and transformer combined tests are improved.
