摘　　要：变压器分列运行时,进线断路器与联络断路器间须加装可靠的联锁装置,避免运维人员转供电时误合断路器,导致发生电气事故和人身安全事故。以2~3台变压器分列运行的的低压配电系统为例,分析有人值守和无人值守时断路器的联锁方案;根据5台变压器分列运行系统的9台断路器电气联锁方案规律,提出多断路器电气联锁控制式模型。When the transformers are operated separately,a reliable interlock device should be installed between the incoming line circuit breaker and the tie circuit breaker to avoid electrical accidents and personal safety accidents caused by the operation and maintenance personnel mistakenly closing the circuit breaker when switching power supply.The low-voltage distribution system with 2~3 transformers operating in sequence is taken as an example,the interlocking scheme of circuit breaker in case of manned and unattended is analyzed.According to the rules of electrical interlocking scheme of 9 circuit breakers of 5 transformers operating system,the electrical interlocking control model of multiple circuit breakers is proposed.
