摘　　要：在输配电系统中,为了提高电力系统的供电可靠性,电网供电普遍采用一主一备模式,即:当主工作电源出现故障不能正常供电时,由备自投装置将负荷自动切换到备用电源供电,从而保证不间断对用户供电。对一主一备进线系统的工程典型配置方案、充放电逻辑、动作逻辑进行分析、优化,提出了进线保护、备自投、自复位功能一体化装置的方案,主要针对一主一备进线系统,且需要主进线电源正常既自动投入运行的系统。可以简化系统设计、降低工程造价成本、方便运行值班人员的操作,等等。In power transmission and distribution system, Power supply commonly used in a master-standby mode in order to improve power system reliability, That is When the main power failure does not to supply electricity the automatic stand-by power switching device will automatically switch to standby power, To ensure uninterrupted power supply to users. This paper has analyzed and optimized typical configuration scheme, charge and discharge logic and action logic of lead-in line system based on master-standby mode, then provide integrated Device Solutions to lead-in line protection, reserved automatic switching and Self-resetting Multi-functional, The device is primarily for lead-in line system . The device can be used to simplify project design, reduce project cost, easy to run the operation on duty, and so on.
