-insulated circuit-breaker panel:
Type
gae
.630 -1LSV(G)-/5/
in modular extensible design up to 24 kV, 20 kA
6.3. Undervoltage release (optional)
When the auxiliary voltage is applied, the trip’s solenoid
energises. The circuit- breaker can be switched ON. If the
auxiliary voltage fall below a specified value, the solenoid is
de-energised and the circuit-breaker switches OFF.
The undervoltage release is set up in the factory and sealed
on the installation board.
6.4. Switching using motor drive (option)
When the supply voltage is applied, the motor drive
runs up immediately and tensions the circuit-breaker’s
spring accumulator!
To test switching using the motor drive, switch on the
supply voltage. The motor drive starts immediately and
tensions the spring accumulator.
The indication states of the spring accumulator are to be
checked mechanically and with the supply voltage. To do
this, switch the drive, as described in Chapter 6.2 and check
the mechanical and electrical switch position indication.
SWITCHING ON
Prerequisite for switching the circuit- breaker ON is that the
mechanical interlocks and the solenoid-operated locks are
not activated.
Press the “ON” pushbutton or activate the remote release’s
control device (switch ON via the making trip) until such
time as the circuit-breaker is switched ON and the switch
position indicator indicates and reports “ON”.
During the switching process, the “spring accumulator
tensioned” indication is no longer visible.
After switching on, the spring accumulator is
immediately automatically tensioned by the
motor drive for an automatic reclosure. The “spring
accumulator tensioned” indication becomes visible
again.
SWITCHING OFF
Check that the switch panel is electrically isolated using
capacitive voltage detecting system (see Chapter 6.5).
To switch the circuit-breaker OFF, press the “OFF” pushbutton
or activate the corresponding remote release’s control
device (switch OFF via the breaking trip) until the circuit-
breaker is switched OFF and the switch position indicator
indicates and reports “OFF”.
