Abstract: At present, power grid companies regard programmatic operations as an important aspect of digital transformation, and encourage the promotion and popularization of on-site implementation of programmatic operations. However, only the auxiliary switch in operation can reflect its position status, which does not meet the requirement of "double confirmation" of position in programmed operation. In recent years, various units have successively organized research on dual confirmation methods, mainly based on image recognition and micro switch methods. The implementation method is complex and the investment is large, but a universal and convenient implementation method has not yet been found. By conducting research on the programmable operation position double confirmation method of isolation switches, a universal double confirmation device is designed and manufactured, including connecting rod travel switch fixing bracket, micro attitude sensor that can be set, position confirmation judgment controller, and other components, which can adapt to the on-site installation requirements of different manufacturers and models of isolation switch mechanisms。
