天然气发电机组中的碳刷材料的特性

来源:http://www.huannengpower.com   发布于:2018-01-26

天然气发电机组碳刷架中的碳刷的资料大多由石墨制成,为了增加导电性,还有用含铜石墨制成,石墨有良好的导电性,质地软而且耐磨。

The data of carbon brushes in the carbon brush holder of natural gas generating units are mostly made of graphite. In order to increase electrical conductivity, graphite brushes are also made of copper and graphite. Graphite has good conductivity, soft texture and wear resistance.

天然气发电机组碳刷架中碳刷能够用于直流电机或交流换向器电机,比方通用电开工具上,象手电钻和角磨机上,皆用到它。他是用来和换向器配合来完成电机电流换向的。

The carbon brush in the carbon brush holder of natural gas generator can be used for DC motor or commutator motor, such as general electric tool, hand drill and angle grinder. He is used to match the commutator to complete the commutation of the electric current.

天然气发电机组碳刷架中碳刷是电机配件(除鼠笼式电动机外)传导电流的滑动接触体。在直流电机中,它还担负着对电枢绕组中感应的交变电动势,停止换向(整流)的任务。理论证明:电机运转的牢靠性,在很大水平上决议于电刷的性能。

The carbon brush in the carbon brush frame of the natural gas generator set is the sliding contact of the electric current of the motor parts (except the squirrel cage motor). In a DC motor, it is also responsible for the task of changing the alternating electromotive force of the armature winding and stopping the commutation (rectifying). The theory has proved that the reliability of the motor's operation depends on the performance of the brush on a large level.

我们可依据碳刷的消费办法,分为两类。一类是有色碳刷,即金属石墨电刷。一类是黑色碳刷。有色碳刷中,含有色金属,主要是铜粉、银粉、其次是铅粉、锡粉、氧化铅粉等,余量为鳞片石墨粉。各种金属粉末含量几随碳刷的技术请求而定。

We can divide into two types according to the consumption of carbon brush. One kind is colored carbon brush, that is, metal graphite brush. One type is black carbon brush. Colored brush, including non-ferrous metals, mainly copper, silver, lead, followed by tin powder, lead oxide powder, flake graphite powder for allowance. The content of all kinds of metal powder depends on the technical request of carbon brush.

当金属含量到达以上时,可不加粘结剂,将粉末混匀后直接压制成型。否则要参加粘结剂(煤沥青、煤焦油或树脂等)。黑色碳刷选用石油焦、沥青焦、炭黑、木炭以及自然石墨粉等,参加局部粘结剂(如煤沥青、煤焦油和人造树脂等)制造的。

When the metal content reaches above, the binder is not added, and the powder is mixed and then formed directly. Otherwise, join the binder (coal tar, coal tar or resin, etc.). Black carbon brushes are made from petroleum coke, pitch coke, carbon black, charcoal and natural graphite powder, etc., and take part in local binder, such as coal tar pitch, coal tar and artificial resin, etc.

高电阻碳刷是采用树脂粘结剂经固化制造的碳刷,而焙烧后的产品称炭刷和石墨刷(以自然石墨为主要原料)经石墨化后的产品称电化石墨刷。

High resistance carbon brush is the resin binder by curing brush manufacturing, and the calcined products called carbon brush and graphite brush (natural graphite as the main raw material) graphitised after product called electrographite brush.
