Research and Application of Intelligent Detection Device of Voltage Potential at Both Ends of Platen

In the substation, combined with the maintenance of protection, safety, measurement and control device, defect treatment or the adjustment of the power grid operation mode, sometimes it is necessary to throw back some protection, safety, measurement and control device pressure plates, and the voltage at both ends of the pressure plate must be measured before being put into the pressure plate. In addition, measuring the voltage potential at both ends of the pressure plate can correctly determine whether the function of the protection, self-safety and measurement and control device is normal and whether it can be put into. This paper analyzes the wrong switch tripping event caused by the wrong gear selection of multimeter when the operator is measuring the voltage at both ends of the platen. The development of a new intelligent voltage potential detection device at both ends of the platen can effectively solve the above problems.
