DC Power Distribution Box (HV BOX)

The set of interfaces between the collector shoes and the pantographs connected to the third rail or upstream grid and the propulsion system are known as high voltage DC power distribution box. In addition to monitoring equipment and voltage and current sensors; they also have the necessary protective equipment for fault conditions. In the design of the JDEVS, the necessary equipment for the protection and prestart of equipment is located in these boxes. It is also possible to integrate, design and manufacture these boxes with the converters required by the propulsion system in a common box.
