Abstract
The utility model provides a carbon brush device for a power generator. The device comprises the power generator which is provided with a rotor and a stator, wherein the rotor is fixedly arranged on a rotating shaft; and a rotor winding is arranged on the rotor. The device is characterized in that carbon brush chambers are respectively arranged on the rotating shaft on the two sides of the power generator; conducting liquid chambers with conducting liquid are arranged at the bottoms of the carbon brush chambers; slide rings which are fixedly arranged on the rotating shaft are also arranged in the carbon brush chambers; the bottoms of the slide rings are immersed in the conducting liquid; and the slide rings of the two carbon brush chambers are respectively connected with a positive lead and a negative lead of the rotor winding. The defects of a solid carbon brush are well overcome by the device, the phenomena of poor contact between the slide rings of the power generator and the carbon brush and relatively high contact resistance are improved, the loss of excitation current is reduced, and the failure of the power generator is reduced.
Description
Technical field
The utility model relates to a kind of carbon brush configuration that is used for generator.
Background technology
In the prior art, technique known is at power field, the carbon brush of generator is generally by solid-state electric conductor manufacturing, need in time to change the carbon brush of serious wear in the use, this solid-state carbon brush can not closely contact with the generator conducting slip ring, be easy to enter dust at carbon brush and slip ring contact-making surface, increased contact resistance, a lot of exciting voltages have been shared on this contact resistance, cause current loss very big, and very easily produce spark and cause fire, this is the existing in prior technology weak point.
Summary of the invention
The purpose of this utility model, be exactly at the existing in prior technology deficiency, and a kind of generator technical scheme with carbon brush configuration is provided, the device of this scheme has well solved the shortcoming of solid-state carbon brush, generator slip ring and carbon brush loose contact, phenomenon that contact resistance is bigger have been improved, reduce the exciting current loss, reduced the generator rate of failure.
This programme is realized by following technical measures: a kind of generator carbon brush configuration, comprise the generator that has rotor and stator, described rotor is fixed in the rotating shaft, rotor is provided with the rotor winding, the characteristics of this programme are: be respectively arranged with the carbon brush chamber in the both sides rotating shaft of described generator, the bottom of described carbon brush chamber is provided with the conduction liquid chamber that fills conductive liquid, the indoor slip ring that is fixed in the rotating shaft that also is provided with of carbon brush, the bottom of described slip ring is immersed in the conductive liquid, and the slip ring of described two carbon brush chambers is connected with negative wire with the positive wire of rotor winding respectively.Described carbon brush chamber is fixed on the generator by fixed support.The both sides of described conduction liquid chamber are provided with splash-guard ring, and described splash-guard ring is fixed in the described rotating shaft.Described slip ring top is provided with the splashproof guide housing, and described splashproof guide housing is fixed on the carbon brush locular wall.Described slip ring is provided with incremental bulge loop and incremental scrobicular ring.Described slip ring is fixed in the rotating shaft by the insulation collar.The indoor overflow pipe that is provided with of described conductive liquid, the outlet of described overflow pipe is arranged on the outside of carbon brush chamber, and the carbon brush chamber is for what seal, and described carbon brush chamber is provided with inspection hole, and the inwall of bottom, described carbon brush chamber is provided with the insulation interlayer.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing in this scheme, slip ring is arranged, the slip ring of two carbon brush chambers is connected with negative wire with the positive wire of rotor winding respectively with respectively, and the part of slip ring is to immerse in the conductive liquid, like this in the rotating shaft rotating process, slip ring just can conduct electricity, and then carry out excitation, the carbon brush that does not need solid, and slip ring immerses in the conductive liquid, also be provided with incremental bulge loop and incremental scrobicular ring on the slip ring, further increased conductive area, reduced contact resistance; The both sides of described conduction liquid chamber are provided with splash-guard ring, described splash-guard ring is fixed in the described rotating shaft, and described slip ring top is provided with the splashproof guide housing, and described splashproof guide housing is fixed on the carbon brush locular wall, when slip ring rotates along with rotating shaft, can avoid conductive liquid to splash everywhere like this; The indoor overflow pipe that is provided with of described conductive liquid, the outlet of described overflow pipe is arranged on the outside of carbon brush chamber, like this when conductive liquid is too much, whom conductive liquid flow out along overflow pipe with regard to, described carbon brush chamber is provided with inspection hole, is convenient to observe the indoor situation of carbon brush, and the inwall of bottom, described carbon brush chamber is provided with the insulation interlayer, be spread across carbon brush when indoor as conductive liquid, the insulation interlayer can effective isolation conductive liquid and carbon brush chamber enclosure.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
