Methods, systems, and apparatus for automated maintenance mode switching

摘要

Methods, devices, and systems for automated maintenance mode switching are described. An example method of controlling a protection assembly mode of operation is described for use in a system having a protection assembly configured to receive power from an upstream power source and provide power and protection to a downstream protection device moveable between a fully engaged position and a fully disengaged position. The method includes determining, by the protection assembly, when a maintenance action is being performed on the downstream protection device, and switching the protection assembly from a normal protection mode to a maintenance mode of operation in response to determining the maintenance action is being performed on the downstream protection device.

1. A protection assembly comprising:
a chassis; a protection device mounted to said chassis, said chassis configured to permit movement of said protection device attached to said chassis between a plurality of positions relative to said chassis, the plurality of positions including a fully engaged position and a fully disengaged position; and a first sensor assembly coupled to said chassis, said first sensor assembly configured to detect when said protection device is in an intermediate position between the fully engaged position and the fully disengaged position and generate a signal indicative of said protection device in the intermediate position.
