Abstract: Introduction was made to main functions and characteristics of the synchronizing device, whose connection system consisted of mainframe, display panel and route selection device. This paper described the inspection conditions of the synchronizing device in detail and analyzed the failure cause of synchronizing switching in of Guangxi water conservancy hinge with the synchronizing device. The result shows that during the early period of design for secondary equipment in power station or substation, designers ought to consider “to prevent power major accidents in the twenty-five countermeasures (relay protection)” and “countermeasure points of electric power system relay protection and automatic safety device against accidents”, to ensure the correctness of design papers and the related wiring connection of secondary circuits.
Key words: synchronism; countermeasure; voltage; grounding; design
