发电机在运行过程中，如果出现叁相负荷不平衡会给机组带来运行上的障碍，会导致发电机组不能正常进行工作。据小编了解，导致发电机组叁相负荷不平衡的原因，燃气发电机组小编认为主要分为以下几点：

During the operation of the generator, if there is three-phase load imbalance, it will bring operational obstacles to the unit and cause the generator unit to not work normally. According to Xiaobian's understanding, the reasons for the three-phase load imbalance of the generator set are mainly divided into the following points:

（1）影响设备的运行出力，发电机设备容量设计是按叁相负荷条件来确定的，如果叁相负荷不平衡，设备容量只能以叁相负荷中大一相为限，因此设备出力降低。

(1) Affecting the operating output of the equipment, the capacity design of the generator equipment is determined according to the three-phase load conditions. If the three-phase load is unbalanced, the equipment capacity can only be limited to the larger one of the three-phase loads, so the output of the equipment will be reduced.

（2）中性线就有电流通过，低压供电线路损耗增大。

(2) There is current passing through the neutral line, and the loss of the low-voltage power supply line increases.

（3）造成叁相电压不对称，使中性点电位产生位移。

(3) Resulting in three-phase voltage asymmetry and displacement of neutral point potential.

（4）中性电流过大，使配电变压器运行温度升高，严重时会将变压器烧坏。

(4) If the neutral current is too large, the operating temperature of the distribution transformer will rise, and the transformer will be burnt out in serious cases.

（5）影响发电机组的输出功率，并使绕阻温度升高。

(5) It will affect the output power of the generator set and increase the winding resistance temperature.

（6）使有的相电压高，另外的相电压降低。

(6) So that some phase voltages are high and others are low.

（7）中性线电流过大，异线可能会烧断。

(7) If the neutral line current is too large, the different lines may be burnt out.

用户们在使用发电机组时一定要注意，不能叁相不平衡，如果没有办法改变它的输出功率，只有经常掉换接线方式，以防造成发电机组的损坏。更多注意事项就来我们网站咨询了解吧。
