The Development Of Calibration Device For Mechanical Properties Tester Of High-voltage Switch

With the development of technology, intelligent type of Mechanical Properties tester for high-voltage switch constantly replacing old ones, but the corresponding calibration device is relatively backward. Most of them are simple functions, low degree of automation, complex check wiring, uncertain additional error, low efficiency, which affecting its development and application. In order to ensure its validity and accuracy of test performance, developing an intelligent calibration device with high reliability, operability that satisfied with the calibration requirements of mechanical properties tester of high-voltage switch is imminent.In this paper, the measuring principle and the overall program of the calibration device are introduced, software and hardware design ideas of the device and specific implementation programs are described in detail, and each interface of the calibration device is designed, and instructions for this device are given.The topic aims at the main performance of mechanical properties tester of high-voltage switch, a calibration device for measuring, displaying and adjusting the power parameters and time parameters is developed. Single chip system is the core of calibration device of mechanical properties tester of high-voltage switch, power parameter measurement circuit and the status signal output circuit are combined into an organic whole to complete the validation work. The main unit circuits are input circuit, AC/DC conversion circuit, A/D conversion circuit, switching circuit, the status signal output circuit and display circuit, etc. The main software modules include the data processing module, the status signal output control module and man-machine interface display module.Finally, the device is proved that measuring accuracy, easy to handle, working properly according to experiments, is reaching to achieve the desired design goals. This device applied for a utility model patents, its market application prospects are broad, and it has great practical value.
