概述
Overview

ETK550 铠装式金属封闭开关设备是翼腾智能小型化成套配电设备。具有防止带负荷推拉断路器手
车、防止误分、误合断路器、防止接地开关处在闭合位置时关合断路器、防止误入带电隔室，防止
在带电时误合接地开关的”五防“ 联锁功能，可以配装 ABB Vmax、Schneider HVX、SIEMENS
3AE、EATON COOPER VN3、GE VB2plus 及翼腾智能 VDK-12 系列手车式中压固封真空断路器，
是一种性能卓越的配电设备。
ETK550 armored metal-enclosed switchgear is a benchmark electrical miniaturization
complete set of power distribution equipment. "Five" to prevent push-pull circuit breaker
handcart with load, prevent mis-pointing, mis-connection of circuit breaker, prevent closing
of circuit breaker when grounding switch is in the closed position, preventing accidental
access to live compartment, and preventing misconnection of grounding switch when live
The anti-interlocking function can be equipped with ABB Vmax, Schneider HVX, SIEMENS
3AE, EATON COOPER VN3, GE VB2plus, and Benchmark Electric VDK-12 series hand-held
medium-voltage solid-sealed vacuum circuit breakers. It is an excellent performance power
distribution equipment.
ETK550-12 的尺寸设计，为客户节省了大量的占地空间，主要用于商业及工业建筑地产、数据中心
及其他工业电网等变电场所。
The size design of ETK550-12 saves a lot of space for customers, mainly used in commercial
and industrial buildings, real estate, data centers and other industrial power grid substation
sites.
