导电滑环越来越多的应用到设备上,因此对导电滑环的质量要求也比较严格,这就得看你选择的厂家技术如何?下面百旋动力给大家总结导电滑环在应用过程中有哪些常见问题?

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.

导电滑环在使用中的常见问题:

Common problems of conductive sliding ring in use:

1、信号导电滑环干扰太大

  1. Signal Conductive Sliding Ring Interferes Too Much

  2. 2-1F603153145-lp.jpg

导电滑环可以用于传输电源跟信号,而电源与信号之间会产生干扰,此干扰分为内部干扰、外部干扰。对于设计者必须明确知道信号的类型,对于特殊信号必须采用专用的导线进行内外屏蔽处理。而对于已经成型的导电滑环,发现导电滑环信号收到干扰,可自行对外部导线进行屏蔽,如果还是无法解决只能重新设计导电滑环内部结构了。

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、防护等级与使用环境不符

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

通常未特别说明的导电滑环,防护级别为IP54。部分客户未另外增加防护的情况下,将其置于有防水要求的场合,使得导电滑环内部进水,引起内部短路,造成导电滑环失效。

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、电路设计无保护电路导致

3. Circuit design leads to unprotected circuit

通常的导电滑环出厂时,均会以5倍工作电压以上的高电压来测试产品的绝缘性能,即使如此,有些工况下,也不能满足需求造成导电滑环被击穿而短路烧毁。

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、导电滑环短路

4. Short Circuit of Conductive Sliding Ring

当导电滑环使用一段时间后出现短路现象有可能是导电滑环寿命到了,或者是导电滑环使用过载导致导电滑环烧掉。一般新的导电滑环如果出现短路显示那就是导电滑环内部绝缘材料出现问题或者刷丝与刷丝直接短路、导线破皮等原因引起的。这个必须采用排除法进行检测。

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、导电滑环过载烧毁

5. Overload Burning of Conductive Sliding Ring

导电滑环允许的最大电流是根据导电环的截面积、电刷接触面积,电刷与接触面的压力,转速等综合因素决定的可安全运行的电流值。超出该值,导电滑环就有可能轻则会有发热,重则接触面打火,甚至电刷与导电环之间形成焊接点。虽然导电滑环的设计阶段会考虑一定的安全系数,但是建议客户按实际使用的最大电流提供给导电滑环生产厂家。

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、导电滑环转动不顺

6. Unsmooth rotation of conductive sliding ring

排除导电滑环装配的问题及轴承选用的问题,造成此类问题的原因,通常是客户选择导电滑环时未提出抗震要求,而使用的环境又有较强的震动。造成导电滑环内的薄壁轴承损坏、塑料主轴破裂等。

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.
