产品简介
Brief introduction to the products

KYN28A-24铠装移 开式交流金属封闭开关设备(以下简称开关设备),适用于户内三相50/60Hz、额定电压24kV的单母 线及单母线分段电力系统的成套配电装置。
主要应用于电厂、中小型发电机送电、工矿企 业配电以及电业系统的二次变电所,作为接 受和分配电能并对电路实行控制、保护和监测。
本开关 设备具有防止带负荷推拉断路器手车、防止误分合断路器、防止接 地开关处在闭合位置时关合断路器、防止误入带电间隔、防止在 带电时误合接地开关的“五防”联锁功能。KYN28A-24开关设 备配置性能优良的VS1系列中 置式高压交流真空断路器或固封式真空断路器。开关设 备二次回路配置先进可靠的控制保护元件,母线采 用热缩绝缘材料或环氧涂覆手段,优化电极形状,柜体结构紧凑,方案组合灵活方便。

The KYN28A-24kV Sheathed Move-Off Style AC Metal-Enclosed Switchgear (hereinafter referred to as Switchgear) is a complete set of power distribution devices for single bus and single sub-bus power system, indoor three-phase 50/60Hz, rated voltage 24kV, which is mainly used for small and medium-sized generators as well as the secondary substation of the mining enterprises for the control protection and testing of the electric circuits. The switchgear has the interlock functions of the “five prevention”, ie to prevent the pushing and pulling of circuit breaker hand cart, to prevent the circuit breaker from error operation, to prevent the operating grounding switch from disconnection, to prevent the operator from error entering the live cabin, to prevent the grounding switch from error connection when it is in live condition. The KYN28A-24kV switching equipment is configged with excellent VS1series infix high-voltage AC vacuum circuit breaker or solid closed-type circuit breaker. The secondary circuit of the switchgear is configged with reliable protection components. The heat-shrinkable insulating material or epoxy coating is adopted for the bus. The electrode shape is optimized. The cabinets are compact.The combination of layout plans is flexible and convenient.
