  • Page 4: Foreword

    This booklet provides information for the Medium Voltage (5kV to 27kV) AMVAC indoor circuit breakers as described below. Note: not all sections of this bulletin appllies to all the types of AMVAC circuit breakers. For example, the racking and interlock sections only apply to the draw-out (removable) versions and do not apply to the fixed-mount breaker styles.

  • Page 5: Introduction & Safe Practices

    NTRODUCTION The purpose of this manual is to provide instructions for unpacking, storage, installation, operation, and maintenance for AMVAC™ vacuum circuit breakers. This manual should be carefully read and used as a guide during installation, initial operation, and maintenance. The specific ratings of each model circuit breaker are listed on the individual nameplates. The AMVAC™ circuit breakers are protective devices.

  • Page 6: Receiving, Handling, And Storage

    ABB representative. ABB is not responsible for damage of goods after delivery to the carrier. However, ABB will lend assistance if notified of claims. Use care in unpacking to avoid damaging any circuit breaker parts.

  • Page 7: Accessories

    ACCESSORIES IFTING The lifting hook is specifically designed for general lifting and lowering of the vacuum circuit breaker, from shipping pallets or for lifting onto and off of work tables. The lifting hook is not designed to be used for insertion or removal of the circuit breaker from the switchgear compartment, instead, the use of an appropriate lift truck is required or serious damage to the breaker may occur.

  • Page 8: Racking Handle

    Racking Handle CAUTION Use of any other racking device not approved by ABB will void the warranty!! ABB will not be responsible for damage caused by the use of racking tools other than ABB’s. ANUAL ANDLE The manual opening handle (1) is designed to open the AMVAC circuit breaker manually.

  • Page 9: Insertion And Removal

    The following rules should always be observed when inserting a circuit breaker into the switchgear compartment.  NOTE: ABB has specific accessories to be used with ABB breakers.  ALWAYS compare the breaker ratings nameplate with the switchgear ratings nameplate. Verify breaker secondary control voltage ratings are in agreement with the switchgear control voltage ratings.

  • Page 11: Racking

    INSERTION AND REMOVAL ACKING AMVAC™ circuit breakers are provided with three positive stop racking positions. “Disconnect” position allows for (door open) manual opening only through the use of the manual opening handle (spring loaded) or operation through the use of the electrical close / open pushbuttons located on the breaker front escutch- eon, provided this operation is performed within 200 seconds from the time control power was last applied.

    STRUCTURE AND FUNCTION IRCUIT REAKER TRUCTURE (Refer to Figure 2) TRUCTURE OF THE CIRCUIT BREAKER POLES The encapsulated poles are mounted on the rear flat section of the circuit breaker enclosure. The live parts of the circuit breaker poles are enclosed in cast resin and protected from impacts and other external influences. With the circuit breaker closed the current path for each pole leads from the upper circuit breaker terminal (25) to the fixed contact (24.2) in the vacuum interrupter (24), then via the moving contact (24.1) and the flexible connector (21) to the lower circuit breaker terminal (22).
  • Page 14 STRUCTURE AND FUNCTION TORAGE CAPACITORS (Figure 2c) The energy for the operation of the circuit breaker is stored electrically in two storage capacitors. The breaker is de- signed in such a way that when the capacitors are fully charged, there is enough energy for an O-C-O (Open-Close- Open)* operating sequence without the recharging of the capacitors.
  • Page 15 STRUCTURE AND FUNCTION IRCUIT REAKER ONTROL All the conditions for control of the magnetic actuator mechanism are defined in a permanently programmed logic module. These conditions are:  Auxiliary voltage must be applied to the AC/DC converter.  The storage capacitors must have sufficient charge for the next switching operation. ...

    OPERATION, INSTALLATION, AND MAINTENANCE NTERLOCKS The AMVAC™ circuit breaker contains a number of interlocks. A description of each interlock follows as encountered during racking of the circuit breaker into the compartment. NTERFERENCE LOCKING A interference blocking plate (Fig. 1) in the circuit breaker compartment prevents under rated circuit breakers from being inserted into higher rated compartments.

  • Page 19: Maintenance

    Maintenance Schedule Establishing a periodic maintenance and inspection schedule are critical to ensure a safe, reliable operating AMVAC circuit breaker. Although the magnetically actuated operating mechanism of the AMVAC circuit breaker is maintenance free, visual inspection and maintenance on other components is required.

  • Page 20: Truck

    MAINTENANCE RUCK The truck requires visual inspection of hardware, lubrication and operations during routine maintenance. With the breaker outside the cell, verify all visible hardware tightness, including handles (9) and wheels (7). Wheels should rotate freely by hand movement. Replace or tighten any missing or loose hardware. With the breaker outside the cell, rotate the racking screw as though racking the breaker to the connect position.
  • Page 21 OPERATION, INSTALLATION, AND MAINTENANCE RIMARY IRCUIT SSEMBLY (Pole) The primary circuit requires visual inspection of hardware, low-frequency withstand voltage testing to insure vacuum, and lubrication during routine maintenance. All insulation material should be clean and free of structural cracks. Some minor cracks are inherent in the insulation material.

  • Page 22: Control Wiring

    RIMARY IRCUIT SSEMBLY (Pole) To verify the integrity of the vacuum interrupters, perform the following low-frequency withstand voltage test: 1. Open the breaker (no control power supplied to breaker). a. Connect the high potential lead to one terminal. b. Ground the remaining 5 terminals and breaker frame. 2.
