Two Panel Switchboard –300A 415V AC 3ph 4 Wire – Network Rail No PA05/02022

 

The 2 panel changeover switchboard to Railtrack PLC specification RT/E/S/21026, and is intended to maximise the reliability of the 415 V AC domestic supply by using automatic selection to choose between a REC and a Railway supply

 

Three Panel Switchboard – 200A 650V AC 1ph 50Hz - Network Rail No PA05/02022

 

The 3 panel changeover switchboard to Railtrack PLC specification RT/E/S/21026, and is intended to maximise the reliability of the 650 V AC signalling supply by using automatic selection to choose between two Railtrack supplies and a separate REC supply

Two Panel Switchboard –100A 400/440V AC 3ph 4 Wire – Network Rail No PA05/02022

The modular 2 panel changeover switchboard to Network Rail specification NR/SP/ELP/21026, and is intended to maximise the reliability of the 415 V AC supply by using automatic selection to choose between two supplies. The equipment comprises two incoming 400V-440V 100A AC supply circuits. Each consists of an incoming 4 pole 600V 100A Switch Disconnector followed by a 3 pole 660V 100A contactor and then an isolating 4 pole 600V 100A Switch Disconnector. The outputs from the isolating Switch Disconnectors feed a bus and this is sectioned with a pole 600V 100A bus isolating Switch Disconnector. The bus feeds the four outgoing supply circuits, two via 4 pole 500V 100A Switch Fuses and two via 3 pole 500V 100A Switch Fuses.

Associated equipment includes a kWh meter, an analogue voltage transducer, phase loss relays and a synchronisation relay.

 

Three Panel Switchboard – 100A 400/440V AC 3ph 4 Wire - Network Rail No PA05/02022

 

The modular 3 panel changeover switchboard to Network Rail specification NR/SP/ELP/21026, and is intended to maximise the reliability of the 415 V AC supply by using automatic selection to choose between three supplies.

 

The equipment comprises three incoming 400V-440V 100A AC supply circuits. Each consists of an incoming 4 pole 600V 100A Switch Disconnector followed by a 3 pole 660V 100A contactor and then an isolating 4 pole 600V 100A Switch Disconnector.

The outputs from the isolating Switch Disconnectors feed a bus and this is sectioned with two 4 pole 600V 100A bus isolating Switch Disconnectors.

The bus feeds the four outgoing supply circuits, two via 4 pole 500V 100A Switch Fuses and two via 3 pole 500V 100A Switch Fuses.

Associated equipment includes a kWh meter, an analogue voltage transducer, phase loss relays and a synchronisation relay.

AC Switchboard 250A

 

Three phase AC Switchboard with a single four pole isolator and four Switch Fuse supplies.

Multi-circuit Distribution Boards

 

The Multi-Circuit Distribution Switchboard to Railtrack Plc specification, and is designed to provide distribution of a number of incoming supplies to their various load circuits.

A system is provided for recognising and identifying a blown fuse in the switchboard to facilitate rapid restoration of a supply in the event of a fuse failure.

The switchboard, pictured above, provides a power supply for signalling, where the continuity of the supply is critical.

D.N.O. Distribution Panel 200A AC

 

The D.N.O. (Distribution Network Operator) Distribution Panel for various applications including Points Heating supplies, consisting of a 200A Isolator, a 200A Fuse Switch and two 100A Fuse Switches.

The panel is also fitted with an Internal Light, Anti-Condensation heaters and a 30mA RCD protected 230V 13A Switched Socket.

TI - Trackside Route Indicators

 

The Buffer Zone Exit Indicator provides a visual indication to train drivers and shunters preparing to exit the Buffer Zone controlled by the Buffer Zone Changeover Panels.

The Indicator displays one of a number of messages depending on the state of the Buffer Zone Changeover Panels:

· Stop – No route set

· Await shunter’s instructions – Route set North sidings

· Await shunter’s instructions – Route set South sidings

TI - Trackside Indicators

 

Trackside Indication for conductor rail:

Power On

Power Off

Indication is by low maintenance LED’s and can be mono-colour or dual-colour.

Used on the Dockland Light Railway System
