KYGC28-10(G)



  • 1. Function
    KYGC28 handcart high-voltage vacuum switchgear is used as the switch device for the
    power distribution, starting. control. commutation, double-current switching and so on of
    such equipment as high-voltage fan and water pump, applicable for the 3-phase AC highvoltage power supply system with 12KV or 17.2kV rated voltage and 50Hz rated frequency.
    Multiple solutions of fan switching
    The switching can be realized by 3-position high-voltage iso-lated switch with corotation.
    isolation and reverse; or by two sets fo 5-pole vacuum contactors; or by changing the plug
    of the handcart. The structure can also be used as the switch cabinet of double-power
    supply switching, like double-power supply high-voltage switch cabinet for winch.
    Multiple modes for starting motor
    Such starting modes as direct starting. reactor voltage reduction starting, frequency
    sensitive rheostat starting and one driving X soft starting can be adopted in accordance
    with the max. allowable stating current of the system, load nature and engine type.
    Advanced and complete protective functions
    KYGC28 switch cabinet can be provided with protection of short circuit. over-current,
    leakage undervoltage and over-voltage in accordance with different applications. The
    protector adopts the traditional electro-mechanical relay, static multi-functional electronic
    relay or microcomputer integrated automatic protector with remote control, measurement
    and communication for no-guard substation.
