FVW28-12(FFK)

户外分界真空负荷开关

Outdoor demarcation vacuum
load switch

概述 / Overview

适应于额定电压为 12kV、额定频率 50Hz 的户外三相交流配电系统中，作为开、合负荷电流和关合电流之用。
适用于变电站、工矿企业及城、农网作保护和控制和城、农网自动化配电网络以及频繁操作的场所。
用于架空线路配电系统用的操作控制开关，有多种型式，FVW28-12 型柱上真空负荷开关具有无油、机构简单、性能可靠无需维护等突出优点，至今已被
广泛使用。该产品与 FDR 型故障检测器或 RTU 遥控终端装置等设备相结合，构成结构十分简单的配电自动化系统，它可以实现架空线路故障的自动定位
和故障段的自动隔离。为了更新我国现有的配电开关设备，使之实现无油化和自动化为特征的配电设备改造的需要。
Adapted to the rated voltage of 12kV, rated frequency 50Hz outdoor three-phase AC power distribution system is, as the opening and closing
load current and close current use.
For substation, industrial and mining enterprises and urban and rural power and control for the protection and urban and rural power distribution
network automation and frequent operation place.
The operation control switch for the overhead lines and distribution systems, there are a variety of types, FVW28-12 type column vacuum
load switch with outstanding merit no oil, institutional simple, reliable performance and maintenance, etc., has been widely used. The product
with the FDR-type fault detector or RTU remote terminal devices and other equipment combine to form a very simple construction of
distribution automation system, which can automatically isolate the automatic positioning of overhead line faults and fault segments. In order to
update our existing distribution switchgear, so as to achieve oil-free and automated distribution equipment needs to be characterized by the
transformation.
