Safety for use
All switching take place with high-voltage compart-
IP4X ment doors closed.
Metal-clad and partition competely, standard de-
gree of protection is IP4X. Ensure personal safety.
Primary circuit insulation provide a platform for a
compact air insulated panel, save area the panel
occupies.
Suitable for all applications. Can realize various
schemes, meet requirement of different customs.
The trucks are interchangeable. It is force-saving
and smoothly to move truck in panel.
Space is provided for multiple cables connections.
Installation and maintenance is convenient.
Simple and effective interlocking prevents
maloperation.
Interlock
A series of interlocks are provided to prevent
KYN61-40.5 maloperation, thus protecting both personnel and the
switchgear itself.
The following operations can take place as the stated
interlock conditions are fulfilled, otherwise operations
must be blocked.
Move the withdrawable part from the test position
to the service position:
CB in to OPEN position
Earthing switch in the OPEN position
Move the withdrawable part from the service posi-
tion to the test position:
CB in to OPEN position
Operate the CB:
Withdrawable part have been locked in the test po-
sition or the service position.
Operate the earthing switch:
Withdrawable part have been locked in the test
position.
