Type PSV Automatic Dead-Front Pad-Mounted Switchgear

Type PSV Automatic Dead-Front Pad-Mounted Switchgear

Highly Configurable & SCADA Ready

Type PSV vacuum interrupter switchgear is SCADA ready and configurable with a variety of power handling and protection components. The Federal Pacific PSV dead-front design provides increased security of protection and switch components from environmental concerns and enhanced isolation of medium-voltage circuits to limit exposure of operating personnel.

Protection Assurance

Circuit Breaker protected way feature a “Protection Assurance” Feature. In the event of power loss, all vacuum circuit breakers (VCBs) can be made to open and VCBs do not reclose until protection is restored. The protective relays are voltage transformer powered.

Federal Pacific’s Dependable Construction

Federal Pacific Automatic Dead-Front Type PSV Pad-Mounted Switchgear is constructed using the same methods and details of the Type PSE gear. The Federal Pacific PSV enclosure design provides increased security of protection and switch components from environmental concerns and enhanced isolation of medium-voltage circuits to limit exposure of operating personnel. Federal Pacific PSV pad-mounts feature a low-profile, heavy-gauge enclosure with a cross-kinked roof to eliminate the potential for standing water. Stainless-steel hinges and hinge pins combined with the padlockable, self-resetting, three-point, auto-latch door security system assures durability while controlling access to the interior.

Typical Features of PSV Vacuum Circuit Breaker Protected Ways

\
Powder epoxy primer and powder polyester topcoat finish coatings are electrostatically deposited and baked on to provide a tough, durable, high-gloss finish with characteristics proven by ANSI/IEEE C57.12.28 standard and UL® testing to protect the metal throughout the service life of the padmounted switchgear.
\
One-piece cross-kinked roof lets water flow off enclosure.
\
Set of three stainless-steel hinges and hinge pins on each door.
\
Low-profile, eleven-gauge steel enclosure, roof and doors.
\
Bottom flange of enclosure is gasketed to protect finish.
\
Padlockable eleven-gauge isolated and heated low voltage control compartment on applicable models.
\
Auto-latch self-latching door security system features stainless-steel hinged, padlockable cover with overhang to shield padlock shackle. Penta-head (optional hexhead) bolt is not exposed when cover is padlocked.Door security system controls access to interior.

Typical Features of PSV Vacuum Circuit Breaker Protected Ways

  • 15kV Dead-Front Pad-Mounted Switchgear
  • Proven Auto-jet® load-break air switching.
  • Auto-Jet® Manual Load-Break Air Switches meet IEEE C37.74 requirements including 3-time fault-closing on switches and fuse mountings.
  • Eleven-gauge pickled-and-oiled steel, all welded enclosure construction. Stainless steel is available.
  • Meets IEEE C57.12.28 cabinet security and enclosure finish requirements.
  • Ventilation louvers are not required in the cable compartments but may be specified.
  • With power fuses, NEMA Class GPO-3 non-hygroscopic fiberglass reinforced polyester barriers block access to the internal bus when the fuse panels are opened.

Typical Features of PSV Vacuum Circuit Breaker Protected Ways

  • 600 amp bushings or 200 amp bushing wells with studs accommodate elbows for load ways.
  • Mar-resistant viewing window of voltage transformers and fuses can be removed for service.
  • Mar-resistant viewing window over Auto-jet® load break air switch for positive open closed indication.
  • Parking stands for IEEE 386 elbows assemblies adjacent to each bushing (or bushing well).
  • Rail mounted relay class current transformers for easy removal and adjustment for pulling cable.
  • Slam latch stainless steel assembly on each door.
  • Separate low voltage lockable control compartment is completely isolated from medium voltage compartment
