Description
(5) УСТРОЙСТВО КОНТРОЛЯ СОПРОТИВЛЕНИЯ(5) RESISTANCE CONTROL DEVICE
изол ции РАЗВЕТВЛЕННОЙ ЭЛЕКТРИЧЕСКОЙ ISOLATION BRANCHED ELECTRIC
1one
Изобретение относитс к электроизмерительной технике и может быть использовано дл контрол сопротивлени изол ции разветвленной электрической сети, содержащей несколько источников электроэнергииThis invention relates to electrical measuring technology and can be used to control the insulation resistance of an extensive electrical network containing several sources of electrical energy.
Известно устройство дл контрол .сопротивлени изол ции электроэнергетической системы, содержащее два генератора, два главных распределительных щита и блок контрол сопротивлени изол ции, подключаемый через переключатель либо к первому, либо ко второму распределительному щиту 1,A device is known for monitoring the insulation resistance of an electrical power system, comprising two generators, two main switchboards and an insulation resistance control unit connected through a switch to either the first or second switchboard 1,
Недостатком устройства вл етс невозможность непрерывного контрол сопротивлени изол ции при работе каждого генератора на свой распределительный щит,The drawback of the device is the impossibility of continuously monitoring the insulation resistance during the operation of each generator on its switchboard,
Наиболее близким потехнической сущности к изобретению вл етс устройство контрол сопротивлений изоСЕТИThe closest to the technical essence of the invention is a device for controlling the resistance of iso-NET
л ции, содержащее два генератора, два главных распределительных щита и два блока контрол сопротивлений изол ции, подключенные каждое к,своему распределительному цигу 2,This module contains two generators, two main switchboards and two insulation resistance monitoring units each connected to its own distribution Tsigu 2,
Недостатком известного устройства вл етс низка точность измерени сопротивлени изол ции при одновременной работе обоих блоков контрол сопротивлени изол ции, обусловленна тем, что распределение токов в измеренных цеп х обратно пропорцио ,нально внутренним сопротивлени м вспомогательных источников напр же ,5 НИИ блоков контрол .A disadvantage of the known device is the low measurement accuracy of the insulation resistance with simultaneous operation of both insulation resistance monitoring units, due to the fact that the distribution of currents in the measured circuits is inversely proportional to the internal resistances of the auxiliary sources, namely, the 5 research institutes of the monitoring units.
Целью изобретени вл етс повышение точности измерени оThe aim of the invention is to improve the accuracy of measuring
