    , ADVANCE , or abbreviated versions of ABB and OEM switchgear. It also contains plug-in primary and secondary disconnects with three physical ANSI operating positions within the cell: Disconnect, Test, and Connected. In the disconnected position there are no electrical connections. In the test position only, the secondary control wiring is connected via a patented disconnect mechanism which allows for remote testing of the breaker operations.

  • Page 5: Introduction & Safe Practices

    NTRODUCTION The purpose of this manual is to provide instructions for unpacking, storage, installation, operation and maintenance for the ADVAC™ vacuum circuit breakers. This manual should be carefully read and used as a guide during installation, initial operation, and maintenance.

  • Page 6: Receiving, Handling, & Storage

    If damage or indication of rough handling is evident, file a damage claim at once with the carrier and promptly notify the nearest District Office. ABB is not responsible for damage of goods after delivery to the carrier.

  • 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 dam- age to the breaker may occur.

  • Page 8: Insertion And Removal

     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 9 INSERTION AND REMOVAL CAUTION Use of any other racking device not approved by ABB will void the warranty!! Approved device shown NSERTION (Refer to [Figure 1] for compartment detail, [Appendix A] for breaker detail) 1. Open switchgear breaker compartment door [H] to its fully opened position.

  • Page 10: Racking

    INSERTION AND REMOVAL ACKING ADVAC™ circuit breakers are designed with three positive racking positions. The Disconnect position allows only manual operation of the breaker without control power and with the shutters closed. The Test Position allows manual and electrical operation of the breaker with control power supplied through the secondary contacts with the shutters closed.
  • Page 11 INSERTION AND REMOVAL → D ISCONNECT 1. Perform visual inspection of the circuit breaker. a. Verify breaker is OPEN (push open button or initiate external electric trip if CLOSED). b. Verify switchgear breaker door is closed and secured. 2. Begin racking procedure using approved racking crank. a.

  • Page 12: Mechanism And Operation

    MECHANISM AND OPERATION The EL operating mechanism of the Advac circuit breakers (in all versions) is fitted with a mechanical anti-pumping device which prevents re-closing due to either electrical or mechanical commands. Should both the closing command and any one of the opening commands (local or re- mote) be active at the same time, there would be a continuous succession of opening and closing operations.

  • Page 14: Description Of El Operation

    MECHANISM AND OPERATION Description of EL Operation The EL mechanism can be charged manually using the spring charging lever or electrically by the spring charging gear motor. While activat- ing one of the above mentioned methods, the cams (2) on the rotating operating shaft (1) move the closing lever assembly (3) to charge the closing spring.
  • Page 15 MECHANISM AND OPERATION Description of EL Operation Activating the closing push button rotates the closing shaft and releases the closing hook (1). The stored energy of the closing spring is transferred to the closing lever assembly (2) which pushes the long levers of the cam/ toggle assembly connected by a pin (3).
  • Page 16 MECHANISM AND OPERATION Description of EL Operation The charging motor (if present) automati- cally rotates the operating mechanism. The closing spring is now charged again and ready for the next closing operation. Activating the opening push button rotates the opening shaft and releases the opening hook (1).

  • Page 17: Interlocks

    MECHANISM AND OPERATION NTER OCKS The ADVAC™ breaker contains a number of interlocks. A description of each interlock follows as encountered during racking of the breaker into the breaker compartment. DANGER MODIFICATION TO INTERLOCKS CAN RESULT IN HAZARDOUS CONDITIONS TO PERSONNEL AND EQUIPMENT.

  • Page 18: Manual Operation

    MECHANISM AND OPERATION ANUAL PERATION The breaker can be operated manually or electrically. Refer to Basic Breaker Layout [Appendix A] for locations of indicators. Inspect initial state of the breaker to determine the operations available from Table 2. a. Closing Spring Charged/Discharged Indicator (6) b.

  • Page 19: Electrical Operation

    Optional test jumpers and test cabinets to connect control power to a withdrawn circuit breaker are available (contact the local ABB sales office for details). 1. Inspect initial state of the breaker to determine the operations available from Table 2 on previous page.

  • Page 20: Control Scheme

    ONTROL CHEME ADVAC™ circuit breakers are available with two control packages. The standard package (see Appendix D) includes charge (MS), close (MC), and open (MO) functions, and 4a and 4b auxiliary contacts for customer use. The optional package (see Appendix D) adds to the standard package 5a and 4b auxiliary contacts for customer use as well as an optional second open/trip coil (MO2) and/or under voltage (MU) open/trip device if required.

  • Page 22: Maintenance

    MAINTENANCE AINTENANCE ADVAC™ circuit breakers are designed for a minimum amount of maintenance. Circuit breakers in a clean, non- corrosive environment require only annual inspection. Dusty or corrosive environments require inspection more often at the discretion of the user. Inspection is required following each interrupted fault.
  • Page 23 The maintenance operations must only be carried out by trained personnel and who follow all the safety regulations. Furthermore, it is advisable to call on ABB personnel, at least in cases for checking the performances in service and for repairs. Cut the power supply off and put the apparatus under safe conditions during the maintenance operations.
  • Page 24 MAINTENANCE Stored energy operating mechanism Carry out the functional test of the operating mechanism after 5,000operations (2,000 operations for 3000 A circuit- breakers) or during ordinary maintenance operations Before doing the test, open the circuit-breaker and carry out the following operations In the case of with-drawable circuit-breakers, take the circuit breaker to the isolated area for test In the case of fixed circuit-breakers: cut off the power supply to the medium voltage circuit and follow proper lock-out tag out procedures as specified by the facility.

  • Page 27: 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 28: Control Wiring

    Lubrication on the primary contacts should be inspected during routine maintenance. Use NO-OX-ID special grade-A grease for the lubrication of primary contacts (ABB No. 713222A, 1 Pt. can). 1VAL050503-MB Rev B Replaces (1VAL057485-MB Rev. C) Oct 2013...
  • Page 29 MAINTENANCE CAUTION Applying abnormally high voltage across a pair of open contacts in vacuum may produce X-radiation. The radiation may increase with the increase in voltage and/or decrease in contact spacing. It is recommended that all operating personnel stand at least one meter away and in front of the circuit breaker during testing.
