Abstract: In order to solve the electromagnetic compatibility (EMC) issues in the current 1E valve position signal processing cabinet of nuclear power plants and ensure the operational reliability of in-service nuclear power units, this research conducts EMC design work from the aspects of power supply, input, output, internal reference ground, and structural shielding of 1E valve position signal processing cabinet. EMC qualification tests are conducted to verify whether the developed Class 1E valve position signal processing cabinet meets the technical requirements. The test results show that the EMC design of the 1E valve position signal processing cabinet achieves the expected goals. The anti-electromagnetic interference ability of key technical equipment is effectively improved, laying the technical foundation for the domestic substitution of 1E valve position signal processing cabinets in nuclear power plants. -
