Automatic Transfer Relay Logic Suitable for Multiple Voltage Connection Modes
The automatic transfer relay is an important means for the power sector to ensure continuous and reliable power supply for users.At present,the conventional automatic transfer relay logic is mainly designed for the bus configuration with voltage transformer wiring mode,which cannot meet the requirements that the bus voltage is taken from the line voltage and there is no bus voltage acquisition application,resulting in limited engineering application of automatic transfer relay.Therefore,this paper proposes an automatic transfer relay logic that adapts to various voltage connection modes.By comprehensively analyzing the automatic transfer relay switching charging logic,voltage/no voltage logic,and automatic transfer relay switching action logic,a comprehensive solution for switching logic of automatic transfer relay is proposed.Practical engineering applications show that the fully functional and automatic transfer relay logic switching device fully meets the requirements of practical engineering applications and has a wide range of engineering applicability.
