Abstract
A shutoff protection device contains an insulation control unit of protected network, which is connected to phases of said network and a grounding device, a control relay. The winding of control relay is connected to the output of insulation control unit which contact is connected to a disconnection circuit of a switch. An input of an optical coupler is in series connected to the winding of control relay, the output of optical coupler is connected to a capacitor charging circuit connected through its discharge circuit in parallel to an amplifier input, to a load circuit of which a reserve relay is connected, which contact is in series connected to the auxiliary contact HYPERLINK "http://www.multitran.ru/c/m.exe?a=110&t=378320_2_1&sc=28" \o "Техника" of switch in the disconnection circuit of a factory-assembled switchgear installed before.
