Abstract
A control unit forms a control center serving as one type of a control panel in an electric power system control system. The control unit accommodates equipments such as a circuit breaker, an electromagnetic switch, a zero-phase current transformer, and an operating transformer, and includes a substantially Z-shaped equipment mounting plate mounted between side plates of the unit to have an intermediate bent portion. The circuit breaker is disposed on a front face of a front mounting portion of the equipment mounting plate, and the current transformer is disposed on a back face thereof. The electromagnetic switch is disposed on a front face of a back mounting portion of the equipment mounting plate, and the thin operating transformer is isolated from other equipments and disposed on a back face thereof. Mounting the thin operating transformer on the back face of the back mounting portion of the equipment mounting plate causes the control unit to contain a bulk electromagnetic switch and other equipments without increasing a control unit size. Further, since the operating transformer is isolated from other equipments, other equipments are never affected in the event of burning accident.
