Description

Изобретение относитс к электроизмерительной технике и может быть использовано дл определени электропередачи в электрических сет х с изолированной и компенсированной нейтралью .The invention relates to electrical measuring equipment and can be used to determine electrical transmission in electrical networks with an insulated and compensated neutral.
Известны способы определени опоры с поврежденной изол цией на воздушных лини х электропередачи путем контрол тока повреждени по металлическим детал м опоры в момент поврезвдени D1.Methods are known for determining support with damaged insulation on overhead transmission lines by monitoring the fault current through the metal parts of the support at the time of cutting D1.
Однако известные способы обеспечивают надежное определение опоры с поврежденной изол цией только в сет х напр жением I10 кВ и вьше, но мало эффективны в сет х 6-35 кВ с изолированной и компенсированной нейтралью .However, the known methods provide reliable detection of a support with damaged insulation only in networks with a voltage of I10 kV and higher, but little effective in networks of 6-35 kV with an insulated and compensated neutral.
Наиболее близким к предлагаемому вл етс способ определени опоры с поврежденной изол цией на воздушных лини х э лектропередачи в электрических сет х с изолированной и компенсированной нейтралью, который основан на дистанционном измерении и сравнении параметров аварийного режима на различных участках сети 2 .Closest to the present invention is a method for determining a support with damaged insulation on overhead electrical transmission lines in electric networks with an insulated and compensated neutral, which is based on remote measurement and comparison of emergency mode parameters in different parts of the network 2.
Недостаток этого способа заключаетс в низкой надежности определени опоры с поврежденной изол цией при больших значени х/переходного сопротивлени между опорой и землей.The disadvantage of this method lies in the low reliability of determining the support with damaged insulation at high x / transient resistance between the support and the ground.
Цель изобретени -. повьш1ение надежности определени опоры с поврежденной изол цией при больших значени х переходного сопротивлени между опорой и землей.The purpose of the invention is. Improving the reliability of determining the support with damaged insulation at large values of the transition resistance between the support and the ground.
