Description

technical field [0001] The invention belongs to the field of detection devices, and in particular relates to a high-voltage electromagnetic valve state detection device and method. Background technique [0002] Power plant high-voltage solenoid valves may have faults such as out-of-tolerance action time, leakage, refusal to operate, and malfunctions during use, which may cause normal operation of related systems in nuclear power plants and even cause certain accidents. For example, leakage of the solenoid valve on the main steam isolation valve of a pressurized water reactor nuclear power plant will cause pressure fluctuations that cannot be maintained, frequent start-up of the oil pump, and even cause the main steam isolation valve to close, seriously affecting the safe operation of the unit. At present, most nuclear power plants use routine inspection, component replacement or overall replacement to carry out preventive maintenance. Corrective maintenance is carried out af...

AI Technical Summary

Problems solved by technology

[0002] When the high-voltage solenoid valve in the power plant is used, faults such as action time out-of-tolerance, leakage, refusal to operate, and malfunction may occur, which may cause the normal operation of related systems in the nuclear power plant and even cause certain accidents.

For example, the leakage of the solenoid valve on the main steam isolation valve of the pressurized water reactor nuclear power plant will cause pressure fluctuations that cannot be maintained, frequent start-up of the oil pump, and even lead to the closure of the main steam isolation valve, seriously affecting the safe operation of the unit

At present, most nuclear power plants use routine inspection, component replacement or overall replacement to carry out preventive maintenance. Corrective maintenance is carried out after obvious faults are found. Little is known about the status and performance of solenoid valves, and there are mis-repairs, missed repairs, and over-repairs. Phenomena such as these have caused major safety hazards to nuclear power plants
