2.3.1 Compartments
Provide high- and low-voltage compartments separated by steel isolating barriers extending the full height and depth of the compartments.
SECTION 26 12 19.10 Page 7
Compartment doors: hinged lift-off type with stop in open position and three-point latching.
2.3.1.1 High Voltage, Dead-Front
High-voltage compartment contains: the incoming line, insulated high-voltage load-break connectors, bushing well inserts, six high-voltage bushing wells configured for loop feed application, load-break switch handle(s), dead-front surge arresters, tap changer handle, connector parking stands with insulated standoff bushings, protective caps, and ground pad.
Minimum high-voltage compartment dimensions: IEEE C57.12.34 , Figures 16 and 17.
a. Insulated high-voltage load-break connectors: IEEE 386 , rated 15 kV, 95 kV BIL. Current rating: 200 amperes rms continuous. Short time rating: 10,000 amperes rms symmetrical for a time duration of 0.17 seconds. Connector shall have a steel reinforced hook-stick eye, grounding eye, test point, and arc-quenching contact material.
b. Loop-feed construction with universal bushing wells. Install primary cable feed on one side with surge arrestor on the loop feed bushing.
c. Bushing well inserts: IEEE 386 , 200 amperes, 15 kV Class. Provide a bushing well insert for each bushing well unless indicated otherwise.
d. One-piece bushings: IEEE 386 , 200 amperes, 15 kV Class.
e. Load-break selector switch: Radial-feed oil-immersed type rated at 15 kV, 95 kV BIL, with a continuous current rating and load-break rating of 200amperes, and a make-and-latch rating of 12,000 rms amperes symmetrical. Locate the 4 position 3 pole load break switch (off A, AB, B) handle in the high-voltage compartment.
f. Provide bayonet oil-immersed, expulsion fuses in series with oil-immersed, partial-range, current-limiting fuses. The bayonet fuses are to be externally replaceable with a hot stick without opening the transformer tank.
