KYN1-12 Drawable Type AC Metal-clad Switchgear
General for KYN1-12 Drawable Type AC Metal-clad Switchgear:
KYN1-12 truck type 10KV HV Switchgear is complied with
International Standards as well as Nation Standards.
It is a draw out truck trolley cubicle. Both of the enclosure and
isolating plate of each functional units is made of 2.5mm cold
rolled steel sheet, the surface is treated with phosphatization,
anticorrosion, static plastic-pouring; Each part is connected by
bolt of high intensity. It is featured by beautiful looking, easy
installation and maintenance.
Structure of KYN1-12 Drawable Type AC Metal-clad Switchgear:
The enclosure of KYN1-12 indoor AC metal-clad draw-out switchgear is welded by bent steel plates. It consists of four parts: instrument compartment, front compartment, rear compartment and truck compartment. A kind of bolt connection is used in between the front compartment and the rear compartment. And a kind of shock absorber is used in between the instrument compartment and the enclosure. Steel plates separate each compartment. Several schemes could be available, such as overhead incoming and outgoing, cable incoming and out-going, contact to left or contact to right, etc.
Product Features of KYN1-12 Drawable Type AC Metal-clad Switchgear:
The frame of the trolley is made of cold rolled steel sheets in the
process of punching and welding. The trolley has separate exhaust
passage to the ceiling. Varieties of trolley have the same height
and depth, so truck with the same specification can be
interchanged. There are isolating position, testing position and
working position inside the trolley, each of them has orientation
device and position indicator. The trolley can be seen on each
position as well as seen on the position indicator. When the
trolley goes into the switchgear, the enclosure can be connected
with earthing system of the switchgear. There are controlling
indicator and off and on indicator of the spring mechanism of the
circuit breaker on the panel of the truck.
The guide rails of the circuit breaker room are firm and flat. The truck can run smoothly on the working position and testing position. The valve is made up of nonmetallic insulating epoxy plates. When the truck is on the isolating position/ testing position, the static contact and the moving contact of the major loop are isolated by valve; When the truck enters into the working position, the valve opens automatically. The off and on condition of the circuit breaker, off and on mechanical position indicators and stored energy/ released energy indicator can be seen on the panel of the trolley. Only when the isolating plates between the truck room and cable compartment are pulled out, can the worker get into the switchgear to install or maintain the cable.
On the upper part of the trolley room, busbar room and cable room, there is compression release device. When the internal fault arc occurs in the circuit breaker or busbar room and cable room, the compression release metal plates at the ceiling opens automatically.
