Design of the Intelligent Joint Debugging and Testing System for Ring Main Unit

An intelligent joint debugging and testing system for ring main unit has been designed according to the detecting requirement so as to improve the detecting efficiency.The basic function of the testing system has been introduced and the the overall system hardware design ideas and core hardware design process have been described in detail.Moreover,a brief description of the software architecture has been given out.Combining the hardware and software,a testing system model,which can be used for intelligent test of phase-to-phase protection,zero-sequence protection,communication and other functions,is set up for ring main unit.Testing results prove that the system has advantages of less failure rate and higher detection veracity rate.
