The invention relates to a vibration test method for an ultra-high-voltage (UHV) all-fiber-optical current transformer. The vibration test method comprises the steps of: installing a primary sensor of the UHV all-fiber-optical current transformer on one side of a UHV circuit breaker; and in order to simulate actual conditions of field operation, performing multiple switching on-off operation on the circuit breaker to cause vibration, so as to assess the vibration resistance of the UHV all-fiber-optical current transformer. On one hand, vibration signals are acquired in the switching operation process, on the other hand, output data of the all-fiber-optical current transformer is transmitted to an expert diagnosis system for recording and analysis by means of an electrical unit and is transmitted to a PC remotely, thereby bringing convenience for people to learn about states of the all-fiber-optical current transformer and analyze causes of possible failures in time.
