Abstract
The invention relates to an intelligent test device for a frame circuit breaker mechanism. A PLC programmable control system is adopted as a control center in the whole process of verification and testing of a spring operating mechanism, the spring operating mechanism is positioned and pressed through a pneumatic mechanical pressing device, and the number of tests and the types of the tests are selected by the programmable control system; an energy storage system has control over a pneumatic element by means of an electromagnetic valve to fix the mechanism and controls a manipulator to simulate manual energy storage and manual switch-on and switch-off, and the programmable control system performs operations in sequence according to a preset procedure. The energy storage system can perform energy storage operation on the spring operating mechanism, a manual switch-on and switch-off simulating system is started to perform switch-on and switch-off operation after the energy storage operation is completed, and the number of tests and test data are acquired and recorded by an optoelectronic device in a test system. An alarm system will work to give a sound-light alarm instruction in the operation process if a fault occurs. A crank arm structure is adopted for the human-simulating manipulator, and thus the electric energy storage mode and the mode of simulating manual energy storage by means of the manipulator can be switched.
