[0002] Slip ring is an electrical component responsible for connecting rotating bodies, transmitting energy and signals. It is usually installed at the rotating center of the equipment and mainly consists of two parts: rotating and stationary. Among them, wind power signal slip ring is an important electrical contact part used to transmit electrical signals and electrical energy of wind turbines. The rotating part mainly includes the rotor, and the stationary part mainly includes the stator. The connection of power and signal is established between the rotor and the stator through sliding contacts.
[0003] Usually, the working environment of wind power signal slip ring is generally open-air. Although there will be certain protective shells, it is still relatively easy to be affected by natural climatic conditions, which makes the wind power signal slip ring prone to failure. For example, the brushes are prone to wear and tear and need to be replaced frequently, otherwise it will affect the normal operation of the equipment; the brushes are prone to oxidation and fall off when running at high temperatures, affecting the performance of the equipment; the friction between the brushes and the contact surface is too large or too small, which can easily cause problems such as poor contact or signal interruption. Usually, when a wind power signal slip ring fails, the entire slip ring can only be replaced, which is difficult to repair and increases the cost of use. In order to facilitate the repair of the slip ring, a wind power signal slip ring that is easy to repair is needed to solve the problem of inconvenient repair. Utility Model Content
