Road Contactor Panels (Shed Distribution Switchboard)

 

On load contactor/fuse panels for depot roads or sidings 2000A, 1500V DC

 

On load contactor/fuse panels with inbuilt off load isolator for depot roads or sidings 1000A or 2000A, 750V DC

 

On load contactor/fuse panels with inbuilt off load isolator/bonding switch for depot roads or sidings 500A or 630A, 630V DC

Overhead Trolley’s & Power Pedestals

 

The Road 630V DC is then fed directly from the Contactor to the 630V DC Traction Power supply overhead supply bars. The Trolley Brush collectors pick up the supply from the supply bars. The Shore Supply Plug is fitted with a Plug Engaged sensor which inhibits the application of Traction Power to the train unless a magnet in the train receptacle to detected.

The Trolley supplies Traction Power to trains in the depot area via a Shore Supply Plug. A high level frangible link disconnects the trolley should the train be moved out of the depot with the plug remaining in the train receptacle.

The pedestal offers a static version of the trolley in lifting sheds.

Bonding Devices and Isolator & Bonding Devices

 

Motorised Bonding Device - 4400A 750V DC – Network Rail No PA05/03165

Off Load/ Fault Make, Single pole bonding of high power circuits. The device shorts the Track Feeder Output circuit to  the running rail (Rectifier Negative) when the DC Track Feeder Breaker and opens.

 

Track Isolator & Negative Bonding Device - 1600A 750V DC – Network Rail Product Acceptance No PA05/02034

Off Load / Fault Make Depot road isolation and automatic negative bonding of conductor rails.

Track Isolator & Negative Bonding Device - 2500A 750V DC Network Rail No PA05/02034

On Load & Off Load / Fault Make Depot road isolation and interlocked negative bonding of conductor rails.

Stabling Panels

 

Manual Off load isolator panels for depot roads or sidings 2000A 1500V DC up to 7 roads in one suite.

Typical 2 Pole Depot Supply System

Below is an example of a Two Pole Depot Shore Supply System, Single Pole systems can also be provided.

 

The complete system is isolated OR alternatively supplied via On Load DC Disconnectors.

The depot is then protected by Depot Distribution Circuit Breakers.

The Breakers feed suites of Depot Road Contactors, typically for a particular shed or section of a shed. Each Suite has its own Incoming Off Load Isolator for contactor suite maintenance.

The make up of this Contactor Suite can contain Examination or Lifting Road Contactors OR Cleaning Road Contactors.

Examination Road Contactors feed Overhead bus bars which in turn feed Overhead Switchable Trolleys.

Lifting Shed Contactors feed Switchable Pedestals.

Cleaning Road Contactors contain more monitoring equipment because they feed the Conductor Rails of the Cleaning Road. This panel is interfaced with the Water supplies and controls Overhead Status Indicators for the Conductor Rail Status.

A Mimic Panel in the DDM office monitors the status of each piece of equipment in the depot power system.
