KYN61-40.5使用说明书讲义.docVIP

1 概述 KYN61-40.5铠装式金属封闭开关设备（简称开关柜）系我厂在原产品的基础上设计改进的开关设备。它适应于三相交流50HZ电力系统，用于接受和分配电能并对电路进行控制、保护及监测。 本开关柜具有各种防止误操作的功能，包括防止带负荷移动手车，防止带电合接地开关和防止误入带电间隔等功能。 本开关柜内配置性能优良的ZN85、VN1真空断路器或ABB公司VD4、HD4系列真空断路器。开关柜是技术先进、性能稳定结构合理、使用方便、安全可靠的配电设备。KYN61-40.5 Metal-clad type removable metal-enclosed switchgear( abbreviation as cubicle) is a kind of improved switchgear which is based on the former products. It’s applicable for 3-phase 50HZ power system for receiving or distributing power and controlling, protection and inspection of circuit. The cubicle has all kinds of fault-prevent function including preventing of moving of trolley with load, fault closing of earth switch, fault entering of loading chamber. 1.1 主要特点 a) 柜体采用敷铝锌板经数控设备加工成型后,用螺栓拼接或铆接而成,结构为全拼装式。 b) 可同时配装ZN85-40.5真空断路器手车、VN1、VD4或HD4真空断路器手车，开关柜主母线贯通无需过渡柜转接。 c) 电缆室空间充裕，相间可保证空气净距大于300mm，相间无需加装绝缘隔板。characteristics a) The structure of the cubicle body is full-assemble type, that means aluminum-zin plate of the cubicle body machined-shaped by digital-control device and joined together with screw or with riveting methods. b) It can be assembled with ZN85-40.5 vacuum circuit breaker trolley, VN1, VD4 or HD4 vacuum circuit breaker together, the getting through of the main bus-bar of the cubicle can be realized without switching of another cubicle. c) With enough space of the cable chamber, the net air clearance between phase can be ensured more than 300mm, no needs for extra isolation separator. 1.2 引用标准 本开关柜依据下列标准进行设计与制造： GB11022 高压开关设备和控制设备标准的共用技术要求GB3906 3-40.5kV 交流金属封闭开关设备和控制设备 GB1984 交流高压断路器 DL/T404 户内交流高压开关设备订货技术条件 IEC60694 2002高压开关设备和控制设备标准的共用技术要求 IEC62271-100 2003高压开关设备和控制设备——第100部分：高压交流断路器 IEC62271-200 额定电压1kV以上52kV及以下交流金属封闭开关设备和控制设备The cubicle manufactured according with standards as follows GB11022 General technical requirements for HV switchgear and control device standard GB 3906 3-40.5Kv AC metal enclosed switchgear and control device GB 1894 AC HV circuit breaker DL/T404
