Manual-spring charging check
1.
Insert the manual-spring charging hand crank into the manual-charging
socket (refer to Figure 2B- page 18).Turn the crank clockwise (about 50 turns)
until the spring- charge / discharge condition indicator shows the
closing spring is -
CHARGED
2.
Repeat the above Spring- Discharge procedure.
3.
Verify the springs are
DISCHARGED
and the circuit-breaker primary contacts are
noted as –
OPEN
on the front panel indicator.
As-found and vacuum-integrity check tests
Perform and record the results of an as-found insulation test.
Perform and record the results of a vacuum integrity check (dielectric) test.
Procedures for these tests are described in the Maintenance section
of this instruction manual.
Save results for future comparisons.
Automatic spring-charging check
The automatic spring-charging features of the circuit breaker must be checked. Control
power is required to automatically charge the closing spring.
Note:
Do not perform the spring-discharge check if the circuit breaker is in the CONNECT
position of a draw out cubicle.
Open the circuit breaker and rack breaker to the DISCONNECT position then perform
the spring discharge check.
For fixed-mounted circuit breaker applications, open any isolator switches on the line side and on
the load side of the circuit breaker before performing the spring-discharge check.
If no isolators exist – verify primary and control circuits are de-energized prior to spring discharge.
Performing a Spring discharge will close the breaker – this is not to
be allowed with breaker connected to live primary circuits.
High-speed moving parts and hazardous voltage will cause death, se-
rious injury and property damage.
Only trained, qualified personnel shall perform any of these functions.
Read instruction manuals and observe safety practices.
