What is the cause of the sparks in the generator set? Let's talk about it:

1、轴承振荡大。一二期大轴都带励磁机，因为轴承长、带的附加设备多了，振荡天然就很难控制到较低。天然气发电机发电机组长期运转，疲惫、老化等等杂乱要素引起轴承振荡加大，电刷跟着震动，将使刷柱摩擦不均、引线及绷簧松动，发作局部冒火花渐渐进一步影响大局。

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、电刷外表不洁。这一点让人忽略的，正常运转的发电机电刷密封在密闭的柜子内，南北电刷中有套在轴上齿轮状轴流电扇，靠转子转动把磨下的石墨碳粉、电刷的发热及时抽走，到达清洁冷却的效果。

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.

假如柜门关不严，或巡检时忘掉关门，外面的粉尘伴跟着热空气吸进电刷，附着在刷柱上，一方面影响电刷散热。另一方面电刷发作火花时因刷柱外表不洁，刷柱之间绝缘强度不行很简单环火。

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.

滑环上车有螺旋状一道道沟槽，这是为了添加电刷散热面积，改进同电刷触摸，使电刷更充沛冷却，一起更简单让碳粉抽走。

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.

柜门若关不严，电扇抽力缺乏外面粉尘也很容易附着在螺旋状沟里，结果是可想而知的。励磁机电刷考虑其电压等级比较低暴露在外面，在此也建议一下检修定期清洁。

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.
