Title: Statical source for tramway auxiliary services
Inventor: RADULESCU VASILE
IPC: B60L1/00
Filed: 2002-04-29
Abstract: The nominal input voltage to the statical source is 750 DC or 600 DC, usually with a voltage variation of +25%...-30%, to which there are also added the atmospheric overvoltages. The direct in-source voltage first passes through a power-line filter and a surge arrester and then it is converted inside an alternative mono-phase voltage inverter of higher frequency than 15 kHz, which discharges on the primary windings of a mono-phase transformer. The mono-phase voltage discharged by the secondary winding of the transformer is applied to a diode rectifier bridge and to a LCR filter, which, at the output, supplies a constant voltage for the direct current consummers. This voltage may be chosen depending on the tramway storage battery and it is adjusted, usually, in the range of 26 to 29 DC. The source limits the maximum current discharged to the consummers of auxiliary services and battery, thereby reducing the output voltage appropriately.
