PROBER FOR TESTING GENERATOR STATOR WEDGE TIGHTNESS WITH ROTOR IN PLACE |
摘要 |
Apparatus for measuring ripple spring deflection to determine stator wedge tightness in an electric generator without removing the rotor includes a low profile carriage insertable in the gap between the rotor and stator. A probe is aligned longitudinally and laterally with holes in the stator wedges with the aid of a miniature television camera on the carriage and extended through an aligned hole to contact the ripple spring. The probe is connected through a cable to the core of a linear variable differential transformer mounted on the carriage which provides an accurate measurement of probe extension. The probe is extended and retracted by an arrangement of cables and springs providing a lost motion coupling which accommodates for seating of the probe against a ripple spring at less than full extension.
