.630 -1LSV(G)-/5/
in modular extensible design up to 24 kV, 20 kA
4.8. Three-position switch drive
The spring drive switches the disconnector and the earthing
switch.
The drive is borne on a U-shaped drive carrier. The robust
spring drive is equipped with both disconnector and
earthing actuating shafts.
Both actuating shafts are hollow shafts with integrated
blade inhibitor. These inhibitors prevent the blades from
swinging through to the opposing contact of the three-
position switch when switching the disconnector or
earthing switch OFF. They are unlocked when the switching
lever is inserted into the actuating shafts.
Function and layout of the actuating shafts can be seen in
the mimic diagram.
The rotary movement of the actuating shafts is transferred
to the switching shaft via toggle links and the operating
lever.
The switch position indicator is controlled by the operating
lever.
All parts of the drive susceptible to corrosion are galvanised.
4.9. Switch panel interlocks
The circuit-breaker panel
gae
.630 -1LSV are provided with
the following interlocks as standard fittings.
• Earthing switch to front cover (front cover interlock)
• Circuit-breaker to disconnector or earthing switch
respectively
• Disconnector to earthing switch
