Design of Dynamic Testing Device for Watertight Opto-electrical Rotary Joint

A new design scheme of photo-electrical rotary joint dynamic detection device is proposed, which can simulate the actual working state of photo-electrical rotary joint and dynamically detect its photo-electrical performance at its actual working speed. According to the scheme, a kind of watertight photo-electrical rotary joint detection device is designed. The optical signal insertion loss, contact resistance, life of the watertight opto-electrical rotary joint and other parameters can be tested under variable rotation speed and high voltage.
