摘　　要：简述了就地化保护的设计理念和设计特点,剖析了将高压就地化保护下放到一次设备开关场后在保护系统的部署和安装方面需要考虑的问题。对高压线路保护提出了直接将保护装置部署在本间隔断路器附近的方案,对变压器保护提出了将主机部署在变压器本体附近、子机部署在变压器各侧断路器附近的方案,对跨间隔的母线保护提出了将主机部署在母线PT间隔、各子机在变压器间隔的方案。This paper briefly described the design concept and design features of on-site protection and analyzed the problems that need to be considered in the deployment and installation of the protection system after the high voltage local protection put into the switching field of the primary equipment. For high voltage line protection,a scheme was put forward to deploy the protection device directly near the circuit breaker and for transformer protection,the scheme was put forward that the host was deployed near the transformer body and the sub unit was deployed near the breaker of each side of the transformer. For inter-span busbar protection,a scheme was proposed to deploy the host at the bus PT interval and each subsystem at the transformer interval.
