Title: Method for operating changeover logic for a reversible converter (two-way rectifier)
Inventor: WEGENER KLAUS DIPL ING
IPC: H02M7/757
Filed: 1993-09-22
Granted: 1994-12-22
Abstract: A method for operating changeover logic (9) for a reversible converter comprising the antiparallel connection, which is free of circulating current, of two converter groups (1, 2) is to be specified. In this method, the changeover logic (9) inhibits the trigger signals for the converter valves of the current-carrying converter group (1, 2) in the event of a change in the polarity of a desired value selection (+/- wI) for the current flowing through the reversible coverter, and enables the trigger signals for the other converter group (1, 2) after observing a recovery time for the converter valves which were hitherto carrying current. In this case, it must be ensured that a minimum trigger pulse duration for the converter valves is complied with prior to the changing over of the current-carrying converter group (1 or 2). The latter provision is achieved according to the invention by the fact that the inhibiting of the trigger signals by the changeover logic (9) is initially prevented for a minimum trigger time of the current-carryign converter valves. <IMAGE>

Abstract: FIELD: chemical industry. SUBSTANCE: hydrocarbon gas stream is divided for first and second streams. First stream is cooled with following condensation, practically, of the whole stream and expansion up to pressure, that is lower, than pressure of distillation column. After expansion and cooling first stream is going to heat-exchanger, in which it is getting in heat-exchanging engagement with much warmer distillation stream, rising from fractionation sections of distillation column. Then division of heated first stream takes place to form cold vapor and stream of liquid. Liquid is fed in column in first position of feeding along center of column, and cooled vapor is fed in column in second position of feeding along center of column. Second stream is expanded up to pressure of column and then is fed in column in third position of feeding along center of column. Distillation stream is cooled by first stream in sufficient degree to make its partial condensation. Then partially condensed distillation stream is divided to ensure feeding of residual flying gas stream and stream of phlegm. Stream of phlegm is fed in column from above. In the cases, in which second stream is being expanded in corresponding expanding device any formed before instant of expansion condensation is combined fully or partially with first stream. The action takes place before instant of cooling and / or expansion or it is fed partially or fully in column in the form of condensed stream along center of column.
