Problems solved by technology

[0004] However, after the stator and rotor are installed in the motor casing, they are inspected. After detecting that there is a problem with the stator winding, the stator and rotor need to be removed. After troubleshooting, they are reinstalled into the motor casing for inspection. Production efficiency, not suitable for mass production requirements

Abstract

The invention discloses a synchronous generator stator winding detection rack. The synchronous generator stator winding detection rack comprises a test board machine frame, a supporting plate, a tool rotor, a motor and an air pump, wherein an opening which allows the tool rotor to penetrate through is formed in the center of the supporting plate, the supporting plate is arranged on the top face of the test board machine frame in a mode that the supporting plate can be driven by the air pump to rise and fall, and the tool rotor is vertically arranged on the top face of the test board machine frame in a penetrating mode. In the detection process, a stator which is fixed to the supporting plate and to be detected falls, and the tool rotor is matched with and sleeved with the stator to be detected, and is driven by the motor to rotate in the stator to be detected. The synchronous generator stator winding detection rack is simple and reasonable in structure and high in detection efficiency, the motor stator and the rotor do not need to be installed into a motor shell and then to be detected, and the problem that the assembling efficiency is affected due to the fact that faults are detected to happen to a stator winding and the motor shell needs to be disassembled is solved.

Description

technical field [0001] The invention relates to the field of synchronous generators, in particular to a test bench for stator windings of a synchronous generator. Background technique [0002] The working principle of the synchronous generator is based on the basic principle of the electromotive force induced by the conductor cutting the magnetic force line. Therefore, synchronous generators have magnetic poles that generate magnetic flux lines and conductors that cut magnetic flux lines. There is an excitation winding on the rotor, and when the excitation current is passed through, since the rotor rotates under the action of the original force, an alternating magnetic field will be generated. The three-phase winding of the stator cuts the magnetic force line in turn. It will induce AC electromotive force of equal magnitude and 120° electrical angle difference. [0003] Whether the winding of the three-phase winding inside the stator is qualified is directly related to whe...
