發(fā)電機(jī)組冒火花是什么原因，下面小編就來(lái)給大家說(shuō)個(gè)一二：
What is the cause of the sparks in the generator set? Let's talk about it:
1、軸承振蕩大。一二期大軸都帶勵(lì)磁機(jī)，因?yàn)檩S承長(zhǎng)、帶的附加設(shè)備多了，振蕩天然就很難控制到較低。天然氣發(fā)電機(jī)發(fā)電機(jī)組長(zhǎng)期運(yùn)轉(zhuǎn)，疲憊、老化等等雜亂要素引起軸承振蕩加大，電刷跟著震動(dòng)，將使刷柱摩擦不均、引線及繃簧松動(dòng)，發(fā)作局部冒火花漸漸進(jìn)一步影響大局。
1. Large bearing oscillation. Phase I and phase II main shafts are equipped with exciters. Since the bearings are long and there are many additional equipment, it is naturally difficult to control the oscillation to a low level. The long-term operation of the natural gas generator set causes the bearing vibration to increase due to fatigue, aging and other disordered factors, and the brush vibrates with it, which will cause uneven friction of the brush column, looseness of the lead wire and tension spring, local sparks and gradually further affect the overall situation.
2、電刷外表不潔。這一點(diǎn)讓人忽略的，正常運(yùn)轉(zhuǎn)的發(fā)電機(jī)電刷密封在密閉的柜子內(nèi)，南北電刷中有套在軸上齒輪狀軸流電扇，靠轉(zhuǎn)子轉(zhuǎn)動(dòng)把磨下的石墨碳粉、電刷的發(fā)熱及時(shí)抽走，到達(dá)清潔冷卻的效果。
2. The brush surface is not clean. It is neglected that the generator brushes in normal operation are sealed in a closed cabinet. There is a gear shaped axial flow fan on the shaft in the North-South brushes. The heat of the ground graphite powder and brushes is removed in time by the rotation of the rotor, so as to achieve the effect of cleaning and cooling.
假如柜門關(guān)不嚴(yán)，或巡檢時(shí)忘掉關(guān)門，外面的粉塵伴跟著熱空氣吸進(jìn)電刷，附著在刷柱上，一方面影響電刷散熱。另一方面電刷發(fā)作火花時(shí)因刷柱外表不潔，刷柱之間絕緣強(qiáng)度不行很簡(jiǎn)單環(huán)火。
If the cabinet door is not closed tightly, or you forget to close the door during inspection, the dust outside is sucked into the brush with hot air and attached to the brush column, which affects the heat dissipation of the brush on the one hand. On the other hand, when the electric brush sparks, the insulation strength between the brush posts is poor due to the unclean appearance of the brush posts. It is very simple to ring fire.
滑環(huán)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(jìn)同電刷觸摸，使電刷更充沛冷卻，一起更簡(jiǎn)單讓碳粉抽走。
There are spiral grooves on the slip ring to add the heat dissipation area of the brush, improve the touch with the brush, make the brush more fully cooled, and make it easier to remove the carbon powder together.
柜門若關(guān)不嚴(yán)，電扇抽力缺乏外面粉塵也很容易附著在螺旋狀溝里，結(jié)果是可想而知的。勵(lì)磁機(jī)電刷考慮其電壓等級(jí)比較低暴露在外面，在此也建議一下檢修定期清潔。
If the door of the cabinet is not closed tightly, the power of the electric fan is insufficient, and the dust outside is easy to adhere to the spiral groove. The result is conceivable. Considering that the exciter brush is exposed to the outside due to its low voltage level, it is also recommended that the exciter brush be regularly cleaned for maintenance.
