摘要:
A switching system for switching between phases in a multi-phase power distribution system includes a switch for selectively connecting a lateral line to feeder conductors of different phases in a multi-phase power distribution system. Feeder terminals of the switch are configured to connect to feeder conductors of the multi-phase power distribution system. At least one output terminal of the switch is configured to connect to the lateral line. The feeder terminals are spaced about the body of the switch. A shaft and a rotatable contact member extending radially from the shaft are configured for rotating within the switch body to selectively connect the at least one output terminal to any one or more of the feeder terminals. At least one controller operates the switch to selectively change connection of the lateral line between the feeder conductors.

In an electrical cord reel, a rotatable member can rotate about a winding axis to spool and unspool a linear material. An input power connector can couple to an electrical power source. An output power connector on the rotatable member can couple to an electrical cord at least partially wound about the rotatable member. A switch is adjustable to allow or prevent electrical current flow from the input power connector to the output power connector. In an aspect, the electrical cord reel includes an electric cord comprising a first power wire, a second power wire, and a signal wire. A method of controlling the electric cord spool system includes energizing the first power wire and the signal wire. The method further includes determining a continuity of the signal wire. The method further includes de-energizing the first power wire when determining discontinuity of the signal wire.

Apparatuses and methods for providing a capability to prevent an automatic transfer switch from automatically switching from a primary to a secondary power source are illustrated. The automatic transfer switch includes a transfer inhibitor that is configured to receive a transfer inhibit signal. In response to receiving the transfer inhibit signal, a switching logic is configured to prevent a contactor of the automatic transfer switch from automatically connecting the secondary source to a load.

A power adaptor (18) for converting AC/DC current to DC current and providing the converted DC current to a portable device (26) is provided. The power adaptor (18) includes a converter (30) and switching means (34a, 34b). The converter (30) includes input ports (31a, 31b) for receiving the input current therethrough and output ports (33a, 33b) for providing the output current therethrough. The switching means (34a, 34b) are coupled to one of the input ports (31b) and operative to control the flow of the input current. The switching means (34a, 34b) are adapted to be detachably connected to the device (26) so that the input current flows only when the device (26) is coupled to the power adaptor (18).
