Provided is a secondary safety measure visualization system of an intelligent transformer station, which can resolve the problem that the isolation of a conventional GOOSE pressure plate and a maintenance pressure plate is not visualized and is easy to leak and fall in, and a safety device will be mis-operated. The secondary safety measure visualization system comprises a hardware structure and asystem module. The system module is stored in the hardware structure. The system module comprises a SCD visualized module, a safety measure visualized module, a communication module, a database moduleand a work ticket module. The invention is advantageous in that a plurality of information sources including network message analyzer in the intelligent transformer station, recorded information, protection logic tree information, monitoring system information are combined; the internal information of the device, the control loop of the device and the safety measure loop can be visualized; the safety measure work of the intelligent safety device and the secondary loop can be simple and visualized, clear and safe and rapid; the difficulty of understanding and grasping the intelligent power grid for operation persons can be reduced, and the reliability and security of operation and maintenance of the transformer power station can be improved.
