To achieve accurate measurement of the safety valve position of the voltage regulator,nuclear power plants usually use safety-grade valve position measurement systems for real-time signal monitoring.The valve displacement measurement technology for nuclear power plants is in-depth studied.A differential inductance principle-based safety valve position measurement system of voltage regulator is designed.The accident resistance of the measurement equipment is improved by adopting a split design scheme,and a qualification test is conducted on the developed test prototype.The test results show that the differential inductance principle-based safety valve position measurement system of voltage regulator has a high measurement accuracy and can achieve accurate measurement of the safety valve position under normal and accident conditions.The system can be subsequently applied to other displacement measurement fields under harsh environmental conditions.
