Abstract

The present disclosure relates to the technical field of switch control. Disclosed are a transmission system and method for a mechanical part and a power electronic assembly. The system comprises: a mechanical transmission shaft, a starting signal generator and a control unit, wherein the starting signal generator comprises a turntable and at least one optical fiber collimator, one end of the mechanical transmission shaft is connected to the mechanical part of a power electronic on-load tap-changer, and the other end of the mechanical transmission shaft is connected to the turntable, the mechanical transmission shaft being configured, when the mechanical part is in action, to drive the turntable to rotate; and the control unit controls, on the basis of the state of a received optical signal, whether to trigger the power electronic assembly of the power electronic on-load tap-changer. The present disclosure utilizes the advantages of stable transmission and strong anti-interference capability of an optical signal, and achieves, by means of identifying changes in the optical signal, real-time monitoring of the mechanical state, thus providing an action starting reference point for coordinated control of action timing, improving the accuracy and reliability of controlling the triggering of the power electronic assembly.
