Slip ring and slip ring electrical system

摘要

A slip ring includes an exterior, a plurality of brushes, a plurality of rings, a brush fixing member that causes the plurality of brushes to contact the plurality of rings and supports the plurality of brushes, and a rotating shaft inserted into the plurality of rings and supports the plurality of rings. The slip ring also includes a reference signal generation unit configured to generate a reference signal, and a detection unit configured to detect a signal, wherein a circuit is formed by the reference signal generation unit, a first brush, which is at least one of the plurality of brushes, a first ring that contacts the first brush, and the detection unit, and wherein a state of contact of the first brush and the first ring is detected based on the signal detected by the detection unit.

1. A slip ring system including an exterior, a plurality of brushes, a plurality of rings, a brush fixing member that causes the plurality of brushes to contact the plurality of rings and supports the plurality of brushes, and a rotating shaft that is inserted into the plurality of rings and supports the plurality of rings, the slip ring system comprising:
a constant voltage circuit configured to stabilize a voltage from an external power supply; a detection unit configured to detect a state of contact of the first brush and the first ring by using a voltage; and an interface configured to issue an alert to a user when the detection unit detects a voltage lower than a predetermined threshold voltage, wherein a circuit is formed by the constant voltage circuit, a first brush, which is at least one of the plurality of brushes, a first ring that contacts the first brush, and the detection unit.
