Selecting Switchgear

The switchgear shown in the circuit diagrams below is rated 8.3/14.4 kV Grounded Wye Maximum Design.

Dimension drawings showing each design can be found on pages 4 through 11 of this bulletin. The continuous-current rating of the Thru-bushings is 200 amperes with an eight-hour overload rating of 300 amperes. Bus bar terminals are copper, rated 300 amperes continuous-current. Thru-bushings and insulators are cycloaliphatic epoxy with square edge skirts and extra creep for superior contamination resistance. Four ground terminals, which accept #6 through #2/0 cable, are included and are installed as shown by the drawings.

Arc-Strangler

Arc-Strangler ®

® Switchblades are interchangeable with

Positive pressure shall be assured by use of stainless steel fasteners and lock washers or compression washers at all connection points. All connections shall provide direct contact of current-carrying parts and shall not depend on current transfer through fastener thread-to-thread contact. Fuses and their blown-fuse indicators shall be visible (when the fuse compartment door(s) are open) without removal of the clearpolycarbonate door safety barrier to allow easy identification of blown fuses without de-energizing or removing the fuse from service. Electrical components shall be “air-insulated” and positioned to allow visual inspection of all internal connections and components without removing the clear-polycarbonate door safety barrier , de-energizing or removing the equipment from service.

The bushings shall be pressure-molded cycloaliphatic epoxy with a 0.75-inch diameter copper conductor that is drilled and tapped 0.375-inch – 16UNC x 1-inch deep on both ends to provide for connection of the bus and/or live parts. Integral shielding shall be provided to eliminate partial discharge caused by off-center mounting and mounting holes that may have sharp edges or burrs. Bushings shall mount in a 3.125-inch diameter opening and bolt in place to allow field replacement with standard tools. The bushing mounting bolts shall be self-locking stainless steel serrated-flange hex-head bolts that “cut” through the enclosure protective finish to ground the integral shielding of each bushing. To assure adequate strength for apparatus support, the bushing shall withstand a minimum cantilever loading of 250 pounds for five minutes without damage. Each bushing shall be tested in free air, mounted in a grounded steel plate not less than 10 inches x

10 inches and shall meet the requirements for 15 kV devices in accordance with the test values of IEEE Standard 386 (latest revision), including 100 percent production testing.

®

® loadbreaking device offer:

Safe loadbreaking . The Arc-Strangler ® loadbreak quickly extinguishes load-current arcs drawn between the mounting contacts and the fuse conductor during loadbreaking operation.

Prevention from accidental closing .

The Arc-Strangler ® loadbreaking device must be cocked before the fuse can be closed into the mounting.

NEMA standard hookstick operation .

Both the pullring and the hinge accept the standard distribution-class hookstick.

The hinge is made with a slot for the hookstick, making fuse removal from— and replacement in—the mounting easy.

Blown-fuse indication . A red button is clearly visible after the fuse has operated.

High-voltage warning . The big warning label (readable when the fuse is hanging open) warns personnel of possible danger.

Optional latch . A plastic latch that gives a positive indication that the device is armed is available as an accessory (See

Page 15).

Operating Principles

The Arc-Strangler ® loadbreaking device is a springloaded sliding sleeve that cuts off the arc drawn between the mounting contacts and the fuse conductor when the fuse is opened while load current is flowing. A pullring at the top of the fuse

(for hookstick operation) and a hinge at the bottom complete the loadbreak device.

The Arc-Strangler ® loadbreak is complete in itself—no auxiliary loadbreaking tool is required and no additional loadbreaking switch in series is necessary. All current magnitudes through the continuous-current rating of the fuse can be interrupted positively and safely under proper conditions.

The loadbreaking assembly includes a stationary core and a sliding molded sleeve that covers the contacts on opening the hinged assembly. The sleeve is made of high-quality material that gives off small quantities of arc-quenching gases under the heat of the arc.
