A switchgear of unilateral maintenance comprises connected to one another: collector bus bars, a bus isolating switch with grounding, a vacuum switch, current transformers, a line insulator with grounding and a zero-current transformer. In addition, the switchgear comprises an auxiliary transformer OLSP type and two voltage transformers of NOLP type. Collector bus bars are connected with the bus isolating switch, the bus isolating switch is connected to the auxiliary transformer of OLSP type and voltage transformers of NOLP type and vacuum switch which is in series connected to current transformers and to the line insulator. In turn, the line insulator is connected to the zero-current transformer. |
