導(dǎo)電滑環(huán)的材質(zhì)要求機械強度大,不但是電的良導(dǎo)體,還要具有耐腐蝕性,在與電刷滑動接觸時,必須具備耐磨性和穩(wěn)定的滑動接觸特性。一般,鋼質(zhì)集電環(huán)的耐磨性好,機械強度大,因此大多用于因極性引起集電環(huán)磨損差較大的同步電機上。
The material of the conductive slip ring requires a large mechanical strength, not only a good conductor of electricity, but also a corrosion resistance. In contact with the brush sliding, it must have the wear resistance and stable sliding contact characteristics. Generally, the steel collector ring has good wear resistance and large mechanical strength, so it is mostly used for synchronous motor with large wear loss due to polarity.
滑環(huán)要求耐腐蝕性時,可使用不銹鋼,但不銹鋼的滑動特性不穩(wěn)定,與電刷組合不合適往往使電刷產(chǎn)生跳動,容易造成電刷溫升過高或異常磨損,所以使用時必須倍加注意。
When the slip ring requires corrosion resistance, stainless steel can be used, but the sliding characteristic of the stainless steel is unstable, and the brush combination is not suitable for the brush to produce beating. It is easy to cause the high temperature rise or abnormal wear of the brush, so it is necessary to pay more attention to the use of the brush.
徑向集電環(huán)是一種非常常見的電器配件,正常運行時,三相繞組通過徑向集電環(huán)引出的電阻短接.上繞有對稱的三相繞組.啟動時,在轉(zhuǎn)子繞組中串入一個啟動電阻,達到了減小啟動電流的目的.徑向集電環(huán)輕度振動時應(yīng)及時處理,以免事態(tài)擴大.如果不及時處理,會致使壓簧和電刷頻繁損壞,徑向集電環(huán)報廢,電機軸徑向磨細.
Radial collector ring is a very common electrical appliance. In normal operation, the three-phase winding is connected by a radial collector ring. There is a symmetrical three phase winding. When starting, a starting resistor is set in the rotor winding to reduce the starting current. If it is not processed in time, the pressure spring and the brush will be damaged frequently. The radial collector ring will be scrapped and the motor shaft will be grinded in radial direction.
