  • Main technical Parameter (refer to sheet 1 )





    Loop power supply principle
    The loop power supply is composed of three basic unit to separate any one of the failure line and ensure the continuous power supply through the other unit. The branch line for the user could separated and protect the transformer which could facilitate the maintenance. The loop power supply could be expanded as per the user's requirements to form various protection plans. Picture 1



  • Feature

    1.8MF material adopted for the switchgear ,modular holes available with E=200.
    2.Switch disconnector ,vacuum load breaker switch, earthing switch and the switchgear door reliably interlocked ,which could avoid miss operation.
    3.Both manual and automatic operation are available.
    4.There is leas sealed pin at the door of measurement chamber and meter chamber .
    5.Prompt tripping could be realized to protect the equipments.
    6.The design facilitate the operation at the front panel and the switchgear could be installed alongside the wall.
    7.The switchgear is featured for its complete interlocking function: the load break switch could be operated to the making status when the switchgear door is closed and locked and the earthing switch to the making position. When the earthing switch is at making status, input the insulation clapboard to its position, the switchgear door then, could be operated.
    8.The Vacuum arc-extinguishing chamber and fuse are reliably connected. So as the fuse & switchgear door and insulation clapboard & the switchgear door .
