METHOD FOR CONTROL OF FALSE DISCONNECTION AND FAILURE OF AUTOMATIC RECLOSURE OF HEAD SWITCH OF POWER TRANSMISSION LINE

摘要

FIELD: electrical equipment.;SUBSTANCE: invention relates to the electrical equipment. According to the method of control of false disconnection and failure of AR of the HS of the power transmission line from the moment of disappearance of voltage, operating current and absence of short-circuit current surge the time count is started, which is equal to the delay time of the HS automatic reclosure, at that, occurrence of voltage and surge of working current is controlled, and if they do not appear at the moment of the counted up time, then conclusion is made on false disconnection and failure of automatic transmission AR of the power transmission line. Proposed method allows obtaining information on false disconnection and failure of HS AR of power transmission line.;EFFECT: technical result is broader functional capabilities of the method by obtaining information on false disconnection and failure of automatic reclosure (AR) of head switch (HS) of power transmission line.;1 cl, 2 dwg
