Description
личйи переменного напр жени на корпусе защищаемого оборудовани , выше допустилюго (например , р Uj 12 В), ток в реле 4 мен ет .евое направление на противоположное. Контакты реле размыкают цепь управлени и отключают электро установку, Таким образом, данна схема защитного отключени , в которой использовано одно пол ризованное реле, обеспеч1юает откл№1ение зиектроустановки при по влении напр жени на корпусе OTHoafienbHo земли и при возникнове1ши нексправкости в самом устройстве защитного отключе1сш.AC voltage on the case of the protected equipment is higher than acceptable (for example, p Uj 12 V), the current in relay 4 changes the opposite direction. The relay contacts open the control circuit and disconnect the electrical installation. Thus, this protective cutout circuit, in which one polarized relay is used, ensures the disconnection of the electrical installation when the voltage on the OTHoafienbHo ground appears and in case of non-fault in the protective disconnect device itself.
