概述
Overview
P/V-12-L550 铠装式金属封闭开关设备是法腾电力公司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，配装 GE 公司 VB2Plus 或 VGV
户内手车式中压固封极柱真空断路器，是一种性能优越的配电设备。
P/V-L-550 armoured metal enclosed switchgear is a small power distribution
equipment for Fateng Electrical Power company. The has the functions of
preventing the vacuum circuit breaker from moving the handcart under the closing
conditionpreventing the handcart with load push-pull circuit breaker, preventing mis-
splitting, mis-closing circuit breaker, closing circuit breaker when grounding switch is
in closed position, preventing mis-entering into live compartment, and preventing mis-
closing grounding switch in live condition. It is equipped with GE VB2Plus or VGV indoor
handcart type medium-pressure sealed pole vacuum circuit breaker, is a superior
performance distribution equipment.
P/V-12-L550 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 P/V-12-L550 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.
