INTERRUPTER REPLACEMENT ON MODELS 2010, 2015, AND 2040 — Continued
Step 31
Replace the access cover retained from Step 20 and
securely tighten the associated
⁵⁄₁₆
—18
³⁄₄
hex-head
stainless-steel cap screws.
Step 32
Remove the shield for the pressure-relief device and low-
gas-pressure indicator from the replacement interrupter.
Discard the shield and its hardware. Reconnect the high-
voltage conductor to the interrupter-end terminal pad
and, on Model 2040, to the transition-box-end terminal
pad.
Step 33
Remove the container from the replacement interrupter
as follows:
(a) Remove and discard the
³⁄₈
—16 zinc-plated serrated
hex nuts which run the length of the container.
(b) Remove and discard the
³⁄₈
—16
⁷⁄₈
and two
³⁄₈
—16
1
zinc-plated hex-head cap screws and flat
washers which attach the
upper
container-half to the
coupling end casting of the interrupter. Also remove
and discard the
³⁄₈
—16
⁷⁄₈
and two
³⁄₈
—16
1
zinc-
plated hex-head cap screws and flat washers which
attach the upper container-half to the indicator end
casting of the interrupter.
(c) Pry the container-halves apart with a screwdriver. The
upper container-half can now be removed and dis-
carded—slotted holes are provided so that a rope or
lifting sling can be attached and the container-half
more conveniently lowered to the ground.
(d) Now remove and discard the
³⁄₈
—16
⁷⁄₈
hex-head
cap screw and flat washer which attach the
lower
con-
tainer-half to the coupling end casting of the inter-
rupter, and the
³⁄₈
—16
⁷⁄₈
hex-head cap screw and
flat washer which attach the lower container-half to
the indicator end casting of the interrupter. Then dis-
card this container-half.
(e) Finally, remove and discard the foam-core inner liner
wrapped around the interrupter.
Step 34
Replace the trip-circuit and control-circuit fuseholders in
the operator or—on newer operators—close the control-
source disconnect switch and replace the motor-and-
closing circuit fuseholder.
Step 35
Attach lifting slings to the four lifting rings on the
replaced interrupter container.
Do not
loop slings from
one end of the container to the other. Carefully lift the
interrupter into the replacement interrupter shipping
crate. Secure the interrupter and close the lid.
Step 36
Ship the replaced interrupter, transportation charges
prepaid, to S&C Electric Company, Repair Center, 1800
Devon Avenue, Chicago, Illinois 60660-1010. To ensure
proper handling, purchasers are asked to obtain from the
nearest S&C Sales Office a special serially numbered
label to place on the shipping crate. Please enclose a
packing slip showing purchase order or requisition
number covering the exchange.
