The failure analysis of ZD6 electric switcher system is fully discussed with methods of Failure Mode, Effect and Criticality Analysis (FMECA) and Fault Tree Analysis (FTA). The failure cause is studied, the reliability of the system is analyzed and evaluated, the methods to improve the reliability and security of the system are found out.
analysis of the problems existing in ZD6 electric switcher and its disparity compared with world advanced level,develops a set of reliability-test equipment of electric switcher and its automatic monitor system;
Installation and debugging method of 38-sized switch are described in the paper in detail and the action process and malfunction disposal of S700K electric switch machine are explained with illustrations.
This paper deals with the hardware composition of the microcomputerized testing system for a power driven switch. It also describes the design idea of the software for sampling and A/D converting the data of pressure, voltage and current.
