Abstract
PURPOSE: To enable a rotor wedge with superior yield strength and impact value to be ecomonically manufactured by using a Cu alloy contg. a specified amount of Ni and Si as a material for the wedge for pressing the field coil of the rotor of a turbine generator.
CONSTITUTION: Rotor wedge 4 for pressing field coil 3 inserted in slot 2 of rotor 1 of a turbine generator is manufactured by using a Cu alloy contg. 1W5% Ni and 0.2W 1.3% Si. This alloy has 40W60kg/mm2 yield strength, 6kg.m/cm2 impact value and superior rupture toughness. Since expensive elements such as Be and Co are not used, wedge 4 of proper quality can be manufactured at smaller material expenses.
