Abstract: A switch board with a casing thereof supported on right and left vertical supports includes a conduction chamber and an upper and lower electricity chambers with a partition wall therebetween. A drawer-type electric device is adapted to operate into and out of the electricity chambers, so that a secondary movable plug of the drawer-type electric device is connected and disconnected to a secondary control stationary plug in each of the electricity chambers. Control lines are connected between the secondary control stationary plug and the control terminal in the upper electricity chamber. Wiring ducts for containing the control lines include control ducts arranged along the ceiling of the casing from the control terminal, vertical ducts communicating with the right and left sides of the control duct, and horizontal ducts for connecting an end of the vertical ducts to the secondary control stationary plug of the upper electricity chamber and the other end thereof to the secondary control stationary plug of the lower electricity chamber.

Abstract: In a power receiving system, a network transformer, a protector breaker and a current detector are connected between the load side of each of a plurality of network lines and a network bus, a breaker is connected to the primary side of the network transformer, the current detector being operative to detect an accident current on the secondary side of the network transformer, and relays or an operation controller is provided which is responsive to the detection signal to open the breaker and protector breaker to switch off accident currents on the primary and secondary sides of the network transformer, whereby the protective range is so expanded as to cover a line section between the network transformer and the protector breaker and the scale of the overall power receiving system is reduced.
