Segments- 3-PHASE TO 2-PHASE/1-PHASE GANG OPERATED VCB SELECTOR - Vans ElectroEngineerings
3-PHASE TO 2-PHASE/1-PHASE GANG OPERATED VCB SELECTOR
• The VCB Selector Switch consists of 2 Nos. of gang-operated, 3 pole Auto Recloser type VCBs
• One gang operated VCB will switch ON for extending 3-phase supply and the other gang operated VCB will Switch ON for extending 2 phase/1-Phase supply.
• The two outgoing lines which are to be extended the same phase supply during 2 phase/1-Phase feed shall be mechanically linked at the incoming side of the 2-phase/1 Phase feed VCB.
• Mechanical and electrical interlocks are provided between the two VCBs, to prevent simultaneous closing of both the VCBs.
• However, it is possible to keep both the VCBS OFF at the same time.
• The VCB Selector Switch will be operated On-load
• The operating mechanism is magnetic actuator
• Compact and light-weight
• Robust construction
• Suitable for Outdoor Duty, protected to Degree of Protection IP55.
• It is possible to install the VCB Selector Switch in an existing Pole/Structure
3-Phase to 2-Phase Gang Opearted VCB Selector
3-Phase to 1-Phase Gang Operated VCB Selector
•The VCB Selector Switch will be electrically operated, with a provision for manual tripping
•The insulation medium is solid dielectric & the interruption medium is vacuum
• SCADA/DMS compatible
• Mechanical and electrical ON/OFF indications
• The control cabinet suitable for outdoor duty, with IP55 degree of protection, and of light weight and is suitable for Pole/Structure mounting
• The Incoming as well as Outgoing Bushings of the VCB Selector Switch are of universal type, suitable for terminating ACSR OH Conductor or Aluminium/Copper Cable
•The VCB Selector Switch has an in-built comprehensive Protection Unit, with a set of suitably rated integral Current Transformers, embedded in the VCB bushings.
•Flexible Protection Options – from basic Overcurrent & Earthfault Relay to comprehensive Feeder Manager
•Optional Metering – from basic ammeter to comprehensive communicable multi-function meter
