發電機在運行過程中，如果出現三相負荷不平衡會給機組帶來運行上的障礙，會導致發電機組不能正常進行工作。據小編了解，導致發電機組三相負荷不平衡的原因，燃氣發電機組小編認為主要分為以下幾點：

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）影響設備的運行出力，發電機設備容量設計是按三相負荷條件來確定的，如果三相負荷不平衡，設備容量只能以三相負荷中大一相為限，因此設備出力降低。

(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）中性線就有電流通過，低壓供電線路損耗增大。

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

（3）造成三相電壓不對稱，使中性點電位產生位移。

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

（4）中性電流過大，使配電變壓器運行溫度升高，嚴重時會將變壓器燒壞。

(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）影響發電機組的輸出功率，并使繞阻溫度升高。

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

（6）使有的相電壓高，另外的相電壓降低。

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

（7）中性線電流過大，異線可能會燒斷。

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

用戶們在使用發電機組時一定要注意，不能三相不平衡，如果沒有辦法改變它的輸出功率，只有經常掉換接線方式，以防造成發電機組的損壞。更多注意事項就來我們網站http://www.cxxrdz.com咨詢了解吧。

Users must pay attention to the three-phase imbalance when using the generator set. If there is no way to change its output power, they can only change the wiring mode frequently to prevent damage to the generator set.
