The existing transmission of electrical energy and/or signals between two rotating parts generally uses contact slip rings.
由于两个相对旋转部件之间有泥浆等流体通过，所以需要设计旋转动密封的结构。在高温、高压、振动及冲击等恶劣条件下，这种旋转动密封非常容易泄漏，从而在滑环之间形成短路等故障，造成仪器电路的损坏。此外，这种接触式滑环工作时容易产生电火花现象，磨损非常快，工作寿命受到限制，而且接触式滑环结构复杂，可靠性低。Since mud and other fluids pass between the two relatively rotating parts, it is necessary to design a rotating dynamic seal structure. Under severe conditions such as high temperature, high pressure, vibration, and shock, this kind of rotary dynamic seal is very easy to leak, resulting in a short circuit between the slip rings and other faults, causing damage to the instrument circuit. In addition, this kind of contact slip ring is prone to sparking when it works, wears very fast, and its working life is limited. In addition, the contact slip ring has a complex structure and low reliability.
