METHOD TO CONTROL SWITCHING OF DISCONNECT SWITCH ON AND SWITCHING BUSBAR SECTIONALISING SWITCH OFF AT DOUBLE-TRANSFORMER SUBSTATION DURING RECOVERY OF NORMAL POWER SUPPLY CIRCUIT OF RING NETWORK

摘要

FIELD: electricity.;SUBSTANCE: according to the method since the moment of voltage appearance at transformer of the primary power source countdown is started of total time equal to delay time for switching of busbar disconnect switch on of the primary power source and delay time switching busbar sectionalising switch off at the substation, and when by the end of the total time countdown operating current consumed from the reserve power source is reduced per a value defined by the reserved load in the line of the primary power source, then the conclusion is made on switching of disconnect switch on and switching busbar sectionalising switch off at the double-transformer substation during recovery of normal power supply circuit of the ring network.;EFFECT: expanded operating performances.;2 dwg
