| Summary: | The introduction of twelve-pulse rectifiers instead of
six-pulse ones at traction substations of urban electric
transport leads to an increase in technical and economic
indicators, energy savings, a decrease in leakage current.
These result in electrical safety of passengers, a trolleybus
driver and depot maintenance personnel. Twelve-pulse
rectifiers can have a serial or parallel connection of sixpulse bridges. With a parallel circuit, it is necessary to have
an equalizing reactor. The implementation of a twelvepulse serial type rectification scheme can be carried out
by industrial development by manufacturers of new dry
converter transformers with different typical power and
new rectifiers (blocks). As part of the new rectifiers, it
is necessary to have tablet avalanche valves with coolers
based on heat pipes due to their advantages over nonavalanche valves. |
