1.3.2 Driving mechanism compartment
This is the compartment in which the switch-disconnector
or the circuit-breaker is actuated, depending on the type
of function.
The mimic diagram for the main medium voltage circuit
is displayed on the cover of this compartment. The
mimic diagram includes all the position indicators for the
actuators.
The cgmcosmos system has, depending on the cubicle
model, the following types of driving mechanism:
B Tilting
l, 2lv
BM Motorised tilting
l, 2lv
AV3
Three-position circuit-breaker: in a
single operation it acts on the circuit
breaker and the disconnector.
v, 2lv
AMV3 Motorised three-position circuit-breaker
v, 2lv
These elements are operated independently, i.e., their
actuation speed does not depend on the speed of the
manual operation.
Driving mechanisms B and BM can be replaced (due to
improved characteristics) in any of their three positions
(connected - disconnected - earthed). While the driving
mechanism is removed, these switch positions can be
blocked by a coupling device whether the function is in
service or not.
1.3.3 Base
Made up of the cable test compartment, the cable
compartment and the gas relief compartment:
Cable test compartment
This is located in the top front section of the base and
has a cover interlocked with the earthing switch, thus
allowing front access to the three medium voltage cable
test connection pistons.
