| Abstract: | A set of the experimental equipment of the contact system in low voltage electrical switch was developed. The step motor is used as the source drive of this equipment and the MCU system as its controller circuits. The contact system is directly driven by the step motor to accomplish the desired movement. With the design and optimization of the control strategy and control program, the parameters and dynamic property of this device are adjustable and controllable. The transmission characteristics of the planar linkage in contact system of the breakers were analyzed and the structural parameters were redesigned and optimized. The mechanical property of this equipment was tested with the results which show that the requirement is basically satisfied. |
