Description
technical field [0001] The invention belongs to the technical field of power equipment detection, and relates to a power equipment monitoring system, in particular to a power transformer intelligent control and monitoring system. Background technique [0002] As the link between the high-voltage transmission line and the low-voltage transmission line in the power supply system, the transformer plays a very important role in the entire distribution network; the normal operation of the transformer is the guarantee for the normal power supply of the transmission network. [0003] Therefore, the running state of the transformer needs to be monitored regularly or in real time to ensure that it is in a normal running state. The utility model patent with the application number CN201220701354.5 in the prior art provides an intelligent control and monitoring system for power transformers. Cables, air temperature sensors, air wind speed sensors, air wind speed sensors and cooler temp...
