Abstract
A device, system, and method for temporarily disconnecting electrical power in an elevator, the device, system, and method including an elevator controller electrically coupled to a power grid via at least one electrical power line, a transformer electrically coupled to the at least one incoming electrical power line, the transformer reducing a voltage to a second electrical line from the incoming electrical power line, and a remote disconnect switch electrically coupled to the transformer via the second electrical line and moveable between a closed position and a disconnect position, with the remote disconnect switch disabling electrical power to the elevator controller when in the disconnect position.
Claims20
A device for temporarily disconnecting electrical power in an elevator, the device comprising:
- at least one remote disconnect switch electrically coupled to a transformer via a first electrical line and moveable between a closed position and a disconnect position;
- wherein the transformer is electrically coupled to at least one incoming electrical power line, the transformer configured to reduce a voltage to the first electrical line from the at least one incoming electrical power line;
- and
- wherein the at least one remote disconnect switch is configured to disable electrical power to an elevator controller that is electrically coupled to the at least one incoming electrical power line when the at least one remote disconnect switch is in the disconnect position.
A system for temporarily disconnecting electrical power in an elevator, the system comprising:
- an elevator controller electrically coupled to a power grid via at least one electrical power line;
- a transformer electrically coupled to the at least one incoming electrical power line, the transformer configured to reduce a voltage to a second electrical line from the incoming electrical power line;
- and
- at least one remote disconnect switch electrically coupled to the transformer via the second electrical line and moveable between a closed position and a disconnect position;
- wherein the at least one remote disconnect switch is configured to disable electrical power to the elevator controller when in the disconnect position.
