D88尊龙發電機機組出現冒火花的出現的原因有哪些?

D88尊龙1、軸承振蕩大。一二期大軸都帶勵磁機,因為軸承長、帶的附加設備多了,振蕩天然就很難控制到低。天然氣發電機發電機組長期運轉,疲憊、老化等等雜亂要素引起軸承振蕩加大,電刷跟著震動,將使刷柱摩擦不均、引線及繃簧松動,發作局部冒火花漸漸進一步影響大局。

1, the bearing oscillation is large. The one or two big axis with the exciter, because the bearing long, with more additional equipment, oscillation is very difficult to control the natural minimum. Natural gas generator long-term operation, fatigue, aging and so on random factors caused the bearing oscillation increase, brush vibrated, the brush is uneven, and the lead column friction spring loose, attack the local sparks gradually further affect the overall situation.

D88尊龙2、電刷外表不潔。這一點讓人忽略的,正常運轉的發電機電刷密封在密閉的柜子內,南北極電刷中心有套在軸上齒輪狀軸流電扇,靠轉子轉動把磨下的石墨碳粉、電刷的發熱及時抽走,到達清潔冷卻的效果。

D88尊龙2, the brush is unclean. Most people ignore this point, the normal operation of the generator brush in sealed cabinet, polar brush center is sheathed on the shaft gear shaped axial fan, by rotation of the rotor to ground heating under the graphite powder, brush the time off, to clean the cooling effect.

D88尊龙假如柜門關不嚴,或巡檢時忘掉關門,外面的粉塵伴跟著熱空氣吸進電刷,附著在刷柱上,一方面影響電刷散熱。另一方面電刷發作火花時因刷柱外表不潔,刷柱之間絕緣強度不行很簡單環火。

If the door is not closed, or forget to close when inspecting, the dust outside is accompanied by hot air to suck into the brush, and it is attached to the brush post, on the one hand, it will affect the heat dissipation of the brush. On the other hand, when the brush stroke is unclean, the insulation strength between the brush columns is not very simple.

D88尊龙滑環上車有螺旋狀一道道溝槽,這是為了添加電刷散熱面積,改進同電刷觸摸,使電刷更充沛冷卻,一起更簡單讓碳粉抽走。

There are spiral grooves on the slip ring, which is to add the heat dissipation area of the brush, improve the touch with the brush, make the brush more cool, and make the carbon powder easier to pump away.

柜門若關不嚴,電扇抽力缺乏外面粉塵也很容易附著在螺旋狀溝里,結果是可想而知的。勵磁機電刷考慮其電壓等級比較低暴露在外面,在此也建議一下檢修定期清潔。前幾天我廠發作過勵磁電刷冒火花被逼停機事情,原因多方面的,往往小事變成大禍。

If the door of the cabinet is not strictly closed, the power of the electric fan is lack of dust and it is easily attached to the spiral groove. The result is imaginable. The excitation electromechanical brush is exposed to the outside in consideration of its low voltage level, and it is also suggested that the maintenance and repair be regularly cleaned. In the last few days, my factory had a magnetic brush sparking and was forced to stop. Many reasons, often small things turned into a catastrophe.
