Turbine shearpin occurs frequently sheared faut as the protection of turbine distributor, leading to hostdefects and faults, reduc?ing unit using the number of hours, affecting the normal operation of unit. In this paper,through theoretical analysis, combined with the oper?ation and maintenance practice for many years, it studys various reasons of shearpin cutting off, and take effective measures to reduce the fault, avoid false positives as far as possible. It will take reference to design, operation and maintenance of hydraulic turbine.
