摘要(Abstract)：
介绍带电气控制的弹簧安全阀在神华国华宁海电厂B厂1000MW超超临界机组中的应用。该安全阀可以实现再热器超压等异常工况的快开功能,试验模式下可进行安全电磁阀动作回路试验,为百万机组安全运行提供了保障,可供同类机组参考。
This paper introduces the application of the electrically-controlled spring safety valve to 1 000 MW ultra-supercritical unit in Shenhua Guohua Ninghai B power plant.It's easy to realize the quick open function under the abnormal conditions such as reheater overpressure,and the loop test of any safety solenoid valve action can also be done in test mode.These provide guarantee for the 1 000 MW unit safety running and offer a reference for other units of the same type.
