ABB safer HV substation by Mira Gorma

  1. 1. David Olofsson, Territory Marketing Manager, HV Breakers and Modules Safer HV Substation Switchgear Modules developed for mining applications © ABB Group November 4, 2013 | Slide 1
  2. 2. Challenges with HV substations on mine sites Operating costs too high Impact of electricity shortages on operations Workplace safety – electricity major mining hazard Solution: Use low maintenance switchgear with extended equipment life cycles Solution: Apply high level of integration to ensure significant level of reliability Solution: Apply foolproof operation and maintenance procedures © ABB Group November 4, 2013 | Slide 2
  3. 3. Hybrid PASS Substation Plug and Play – Foolproof Operation  66 kV PASS M00      A substation bay in one module © ABB Group November 4, 2013 | Slide 3  Each PASS module is equivalent to a complete switchgear bay with all functions: CB, DS, ES, CT, VT - in one module Flexible configuration: single busbar, double busbar, double breaker Operating and breaking functions integrated in an SF6 encapsulated enclosure Slip on CTs Maintenance free composite bushings Pre-assembled and pretested in factory Wide range of application (Ice and Sand: -50°C; +50°C)
  4. 4. Hybrid PASS Substation Plug and Play – Foolproof Operation A substation bay in one module © ABB Group November 4, 2013 | Slide 4 BENEFITS TO YOU  Great performance in harsh mining environment  High reliability due to the reduced number of components  Less probability of unplanned outages  Easy transportation to an don the site  Fast installation and commissioning, no need to repeat HV testing at site  Low maintenance cost due to high reliability and sealed HV parts  Life cycle cost significantly lower than traditional technologies  Modular approach – easy to extend / retrofit
  5. 5. PASS – All switching from control room Plug and Play – Foolproof Operation 66 kV PASS M00 with VT 1. Closed Position 2. Disconnected 3. Earthed Complete isolation/earthing from the safety of the control room © ABB Group November 4, 2013 | Slide 6
  6. 6. PASS – Mechanical interlocking Plug and Play – Foolproof Operation Foolproof mechanical interlocking to ensure safe earthing © ABB Group November 4, 2013 | Slide 7
  7. 7. PASS – Key 1, Cut all control circuits Plug and Play – Foolproof Operation Cut CB control circuit 1 Cut CB control circuit 2 Cut DS/ES control circuit Electrical interlock, mechanical cut of control circuits © ABB Group November 4, 2013 | Slide 8
  8. 8. PASS – Key 2, Disconnector interlock Plug and Play – Foolproof Operation Mechanical Interlock © ABB Group November 4, 2013 | Slide 9
  9. 9. PASS – Key 3, Circuit breaker interlock Plug and Play – Foolproof Operation Mechanical Interlock © ABB Group November 4, 2013 | Slide 10
