ABB IB 6.2.15.7-1C FORWARD This booklet provides information for the ADVAC breakers as described below. Not all sections of the bulletin apply to all types of ADVAC circuit breakers. For example, the racking and interlock sections do not apply to the fixed mount breaker styles. -
Page 4: Introduction & Safe Practices
ABB IB 6.2.15.7-1C 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 5: 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 6: Insertion And Removal
ABB IB 6.2.15.7-1C INSERTION AND REMOVAL NSERTION AND EMOVAL This section describes the process for inserting the breaker into the disconnect position of the switchgear and the removal of the circuit breaker from the disconnect position. Racking of the circuit breaker to and from the test and disconnect position is covered in the following section. -
Page 7: Racking
ABB IB 6.2.15.7-1C 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 8 ABB IB 6.2.15.7-1C INSERTION AND REMOVAL HROUGH ISCONNECT 1. Perform visual inspection: a. Verify Close/Open Indicator shows OPEN b. Verify switchgear Door is CLOSED. 2. Actuate (push down) Position Release Lever (9) to begin racking from Test position a. Begin racking in the COUNTER-CLOCKWISE direction b.

Page 9: Mechanism And Operation
ABB IB 6.2.15.7-1C MECHANISM AND OPERATION ECHANISM AND PERATION (Refer to Fig. 2A And 2B) The ADVAC™ medium voltage circuit breaker uses a spring for stored energy. The Closing Spring (11) is a toroidal spring. This spring supplies the energy necessary to close the breaker and assists with the opening. During the closing operation, Opening Springs (6) (compression type) are charged along with Contact Springs (4) (also compression type) in the pole assembly. - Page 10 ABB IB 6.2.15.7-1C MECHANISM AND ASSEMBLED POLE 1a Upper contact terminal Kabelabgangsfeld 1b Lower contact terminal 2 Vacuum interrupter 2a Fixed contact 3 Moving contact 4 Contact force spring 5 Push Rod (Insulated coupling rod) 6 Opening spring 7 Rocker Arm (Transmission Lever)

Page 11: Interlocks
ABB IB 6.2.15.7-1C 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 16: Maintenance
Charging Motor (D) in the mechanism (See Fig 4b). Remove any grease on the breaker frame. Use ISOFLEX TOPAS NB52 grease for lubrication (ABB No. ????????, 4 oz. tube). If the grease becomes caked and dirty, remove with a clean cloth and reapply lubrication. Use of incorrect lubricant may cause breaker to malfunction. - Page 17 ABB IB 6.2.15.7-1C MAINTENANCE See Fig 4B below DESCRIPTION DESCRIPTION ROCKER ARM AUXILIARY SWITCHES MOTOR LIMIT SWITCH MAIN SHAFT CLOSE COIL CHARGING MOTOR CLOSE PUSH BUTTON CLOSING SPRING OPEN PUSH BUTTON SECONDARY WIRING OPEN/CLOSE INDICATOR SHAFT SUPPORT BUSHING ANTI-PUMP CIRCUIT BOARD...

Page 18: Truck
ABB IB 6.2.15.7-1C MAINTENANCE RUCK (Refer to Fig. 5) 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 (1) and wheels (2). Wheels should rotate freely by hand movement. Replace or tighten any missing or loose hardware. -
Page 19: Control Wiring
Apply distilled water to the cloth to remove any difficult dirt. DO NOT return the breaker into service until the insulation surfaces are completely dry. 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). - Page 20 ABB IB 6.2.15.7-1C MAINTENANCE A. Current energizes 52TC 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.
