Rectifier unit type PD 1700/3,3 EB
Purpose
Diode rectifier PD-1700/3,3 EB is dedicated to provide power supply to the railroad traction system 3,3 kV DC.
General characteristics
Diode rectifier is an element of rectifier unit including three- or four-winding transformer and shunt reactor. Main features:
- elements are assembled on a steel frame so can be fixed firm to the ground (slots Ø14 - for anchors),
- the rectifier is built with 2 diode sets connected in series including diode bridge built with diodes and RLC circuits,
- 12 pulses,
- indoor, free-standing,
- degree of protection IP 20,
- operating with trafo 15/20 kV or 110 kV,
- easy modernization and extension due to construction frames connected by screws.
Features
- highest quality product of European producer,
- compact design,
- equipped with high-tech devices,
- safe and easy maintenance,
- decreased level of diode module heating up due to unique design,
- minimal needs of maintenance and inspections frequency,
- decreased level of vibrations due to innovative design,
- short time of delivery,
- environmental-friendly production and operation,
- professional manufacturer's service.
