340.下列对超转保护组件( )的描述哪个是错误的?( )Which following description is wrong about OPU.

　通过超转保护组件(OPU)可实现N1和N2超转保护. Through the OPU to provide N1 and N2 overspeed protection.

　超转保护组件(OPU)独立于EEC Super protection components (OPU) independent of the EEC

　低压涡轮超转(LPTOS)保护功能是通过超转保护组件(OPU)实现的. Ultra low pressure turbine (LPTOS) protection function is through the super protection components (OPU)

正确答案：C

解析：

题目解析题目中描述了超转保护组件（OPU）的不同特点，要求选择描述错误的选项。答案是C，因为超转保护组件（OPU）并不用来实现低压涡轮超转（LPTOS）保护功能，而是用来提供N1和N2的超转保护。
