Medium Voltage Switchgear KYN28A Metal - Clad Mid - Mounted AC
Switchgear
Overview
KYN28A-12 Indoor Metal–clad Mid–mounted Switchgear (hereinafter
called as “switchgear”), is a 3~10kV three phase AC 50 Hz complete distribution device of
single busbar and its sectional system. It is mainly used to
control, protect, and supervise circuits for the power supply of
plant, medium or small generator, distribution of factory and
mining, as well as power acceptance and transmission from the
secondary substation in the power system, starting of large HV
electromotor and so on. The product can meet IEC298,GB3906
standards. It has the functions to prevent from moving the handcart
of circuit breaker alive, opening and closing circuit breaker by
mistakes, or doing it while the earthing switch is at closing
position, entering the alive chamber, as well as the closing
interlock of earthing switch by mistakes while it is alive .The
product can be used together with VS1, VD4, VB2, 3AH5, 10-VPR
vacuum circuit breaker, it is a superior power distribution unit
for performance.
