An emergency lighting self-service power supply system in a transformer station belongs to the field of emergency lighting devices. The emergency lighting system adopts an LED luminescent device as a light source, a piezoelectric energy collector group is arranged on a transformer body or the attachment structure of a transformer, and energy produced by the vibration of the transformer can be collected under a resonance state, and converted to be electrical energy; electrical energy collected by the piezoelectric energy collector group is converted to be DC electric energy by adopting a rectifying circuit, and the DC electric energy is sent to a storage battery for energy storage through a charging circuit; the power source output end of the storage battery is connected into the emergency lighting system; in case of power loss of the power supply in the AC station of the transformer station, the emergency lighting system can be connected with the power source output end of the storage battery automatically, so as to provide a power supply for the LED luminescent device, and the emergency lighting function of the emergency lighting system in the transformer station is achieved. Not only can the energy-saving and cost-reducing effect be played, but also a damping and noise reducing effect on the transformer is achieved. The emergency lighting self-service power supply system can be widely used in the field of emergency lighting in the transformer station or the designing and the manufacturing of switch emergency operation power supplies.
