KYN28A-12型中置式开关柜标准化设计研究

摘要

为满足不同厂家设备在一定范围和一定时期的通用互换使用,提升开关柜设备的运维便利性,选择目前市场上应用较多且运行相对成熟可靠的KYN28A-12型中置式开关柜开展标准化设计研究,介绍了标准化设计的目的、设计思路、输入条件和主要设计内容.重点分析了KYN28A-12型中置式开关柜的典型方案确定.对一次接口及土建接口、二次接口以及关键元件的标准化设计原则及结果进行了详细说明,在满足配网设备需求的基础上兼顾变电站中配电设备的要求,提出了统一的标准化设计方案,为后续标准化建设工作提供重要支撑.%In order to realize the compatibility and interchange in a certain scope and period between equipment manufactured by different manufacturers,and to improve the operation and maintenance convenience of switchgear equipment,a standardization design study is made on the equipment KYN28A-12,a relatively mature and reliable type of middle mounted switchgear that has been mostly applied in power grid.The paper introduces the purpose,procedure,input conditions and the main contents of the design.The focus of the design is put on the determination of several typical solutions of KYN28A-12 middle mounted switchgear,and a detailed description is made of the standardization design principles and results for primary interface,civil work interface,secondary interface and key components.A standardized design scheme is proposed to meet both the needs of the distribution network equipment and the distribution equipment in the substation,which can provide an important support for the follow-up standardization works.
