A nuclear reactor coolant pump motor rotor reset measurement device and method

Abstract

The present application belongs to the field of nuclear power plant reactor coolant pump motor unit installation and test, and particularly relates to a nuclear reactor coolant pump motor rotor reset measuring device and method, which comprises: a detection assembly and a data processing assembly; the detection assembly is multiple sets, and is arranged on the upper slip rotor and the lower flywheel of the motor, respectively; the data processing assembly comprises a control box and a remote control PC end; the detection assembly, the control box and the remote control PC end are connected in sequence, the detection assembly measures and collects the rotor position, generates measurement and collection data, and transmits the data to the control box; the control box receives the measurement and collection data transmitted by the detection assembly, processes the data, generates measurement result data, and transmits the data to the remote control PC end; and the remote control PC end receives the measurement result data transmitted by the control box, and displays the data. The device has simple structure and convenient operation, and can realize the rotor reset after the no-load test of the reactor coolant pump motor.
