導電滑環越來越多的應用到設備上,因此對導電滑環的質量要求也比較嚴格,這就得看你選擇的廠家技術如何?下麵AG亞遊登陸地址動力給大家總結導電滑環在應用過程中有哪些常見問題?

More and more conductive sliding rings are applied to equipment, so the quality requirements of conductive sliding rings are stricter, which depends on the technology of the manufacturer you choose. Below, Baixuan Power summarizes the common problems of conductive sliding rings in the application process.

導電滑環在使用中的常見問題:

Common problems of conductive sliding ring in use:

1、信號導電滑環幹擾太大

  1. Signal Conductive Sliding Ring Interferes Too Much

  2. 2-1F603153145-lp.jpg

導電滑環可以用於傳輸電源跟信號,而電源與信號之間會產生幹擾,此幹擾分為內部幹擾、外部幹擾。對於設計者必須明確知道信號的類型,對於特殊信號必須采用專用的導線進行內外屏蔽處理。而對於已經成型的導電滑環,發現導電滑環信號收到幹擾,可自行對外部導線進行屏蔽,如果還是無法解決隻能重新設計導電滑環內部結構了。

Conductive sliding ring can be used to transmit power and signal, and there will be interference between power and signal, which can be divided into internal interference and external interference. For the designer, the type of signal must be known clearly. For the special signal, special wires must be used for internal and external shielding. For the formed conductive slip ring, it is found that the signal of the conductive slip ring is disturbed, and the external conductor can be shielded by itself. If it is still unable to solve, the internal structure of the conductive slip ring can only be redesigned.

2、防護等級與使用環境不符

2. The protection level is not in conformity with the use environment.

通常未特別說明的導電滑環,防護級別為IP54。部分客戶未另外增加防護的情況下,將其置於有防水要求的場合,使得導電滑環內部進水,引起內部短路,造成導電滑環失效。

Usually not specifically specified conductive slip ring, the protection level is IP54. If some customers do not add additional protection, they will be placed on the occasion with waterproof requirements, which will cause the internal water intake of the conductive sliding ring, resulting in internal short circuit and the failure of the conductive sliding ring.

3、電路設計無保護電路導致

3. Circuit design leads to unprotected circuit

通常的導電滑環出廠時,均會以5倍工作電壓以上的高電壓來測試產品的絕緣性能,即使如此,有些工況下,也不能滿足需求造成導電滑環被擊穿而短路燒毀。

Usually when the conductive slip rings leave the factory, the insulation performance of the products will be tested by high voltage above 5 times the working voltage. Even so, under some conditions, the conductive slip rings can not meet the demand, resulting in the breakdown and short-circuit burning down of the conductive slip rings.

4、導電滑環短路

4. Short Circuit of Conductive Sliding Ring

當導電滑環使用一段時間後出現短路現象有可能是導電滑環壽命到了,或者是導電滑環使用過載導致導電滑環燒掉。一般新的導電滑環如果出現短路顯示那就是導電滑環內部絕緣材料出現問題或者刷絲與刷絲直接短路、導線破皮等原因引起的。這個必須采用排除法進行檢測。

When the conductive sliding ring is used for a period of time, the short circuit phenomenon may be that the service life of the conductive sliding ring has reached, or that the overload of the conductive sliding ring causes the burning of the conductive sliding ring. Generally, if a short circuit appears in a new conductive sliding ring, it is caused by the problem of insulation material inside the conductive sliding ring, or the direct short circuit between brush wire and brush wire, and the breakage of conductor skin. This must be detected by exclusion method.

5、導電滑環過載燒毀

5. Overload Burning of Conductive Sliding Ring

導電滑環允許的最大電流是根據導電環的截麵積、電刷接觸麵積,電刷與接觸麵的壓力,轉速等綜合因素決定的可安全運行的電流值。超出該值,導電滑環就有可能輕則會有發熱,重則接觸麵打火,甚至電刷與導電環之間形成焊接點。雖然導電滑環的設計階段會考慮一定的安全係數,但是建議客戶按實際使用的最大電流提供給導電滑環生產廠家。

The maximum allowable current of the conductive slip ring is determined by the cross-sectional area of the conductive ring, the contact area of the brush, the pressure between the brush and the contact surface, and the rotational speed. Beyond this value, the conductive slip ring may heat slightly, lightly, lightly, lightly on the contact surface, and even form a welding point between the brush and the conductive ring. Although a certain safety factor will be considered in the design stage of the conductive sliding ring, it is recommended that customers provide the manufacturer of the conductive sliding ring with the maximum current actually used.

6、導電滑環轉動不順

6. Unsmooth rotation of conductive sliding ring

排除導電滑環裝配的問題及軸承選用的問題,造成此類問題的原因,通常是客戶選擇導電滑環時未提出抗震要求,而使用的環境又有較強的震動。造成導電滑環內的薄壁軸承損壞、塑料主軸破裂等。

Eliminating the problem of assembling conductive slip rings and selecting bearings, the reason for this kind of problem is that customers usually choose conductive slip rings without putting forward aseismic requirements, and the environment used has strong vibration. It causes damage to thin-walled bearings in conductive sliding rings and rupture of plastic spindles.
