Abstract:
Abstract:In the preventative test of No.4 turbo generator for Guangdong Zhuhai Jinwan Power Generation Company Limited, the direct current resistance of rotor is measured out of limit. This paper takes advantage of the direct current resistance differences among different rotation angles of rotor to determine the fault location, and result shows that main reason of the overlarge direct current resistance is the looseness of connection parts of conductive lever.
Key words: Keywords:generator, rotor, direct current resistance, conductive lever, poor contact
