Strut type electronic current transformer one-time vibration detecting device and method

The invention provides a strut type electronic current transformer one-time vibration detecting device which comprises a strut type electronic current transformer and a contact monitoring circuit. The strut type electronic current transformer and the contact monitoring circuit are respectively connected with a breaker. The contact monitoring circuit is connected with an industrial personal computer through a collecting card. The strut type electronic current transformer is connected with the industrial personal computer through a merging unit and a photoelectric converter in sequence. The invention further provides a method based on the detecting device. Opening operation, closing operation and opening-closing-opening operation are carried out on the breaker in sequence, and vibration output verification is carried out on the current transformer according to the industrial personal computer. Compared with the prior art, according to the strut type electronic current transformer one-time vibration detecting device and method, vibration encountered by the electronic current transformed in an intelligent substation can be simulated, therefore, the current transformed is verified, relay protection malfunctions are prevented from being caused by error output of the electronic current transformer, and safe operating of a power grid is guaranteed.
