Abstract
The invention discloses an intelligent transformer load management system which comprises a processor. The processor is connected with one side of optoelectronic isolator through an SPI bus, the other side of the optoelectronic isolator is respectively connected with A/D converters, a relay and a switch value input, the A/D converters are connected with an analog signal and a TC signal respectively, the relay is connected with an external electric appliance, the processor is provided with an SD card port, a USB port and an indicator light, and the processor is connected with a communication port through the other optoelectronic isolator. The TC signal comprises a temperature measurement cable, an air temperature sensor, an air wind speed sensor, a detection signal of the air wind speed sensor and a detection signal of a cooler temperature sensor. The system measures the oil temperature of the top layer of a transformer in real time and predicts temperature changes of the transformer according to external environment factors and current operation conditions, pre-warns for an exceedingly hot condition which may occur to the transformer on the condition that the transformer operates in an overload state, provides corresponding predicted overload operation time so as to improve the utilization rate of the electricity transformer in the greatest degree, and enables the transformer to operate in an energy-saving and efficient mode.
