Customers often say that the generator set will not work after a period of time, and the generator is easy to break down. In fact, under normal circumstances, if it is equipped with a generator with sufficient copper power, it will not break down. Only the diesel engine may have problems. However, many users do not pay attention to the wiring mode of their generator set, resulting in three-phase imbalance of coking generator set, In this way, over time, the generator set is prone to problems. So, what is three-phase imbalance?

由于焦化发电机组组输出的电是三相四线的,就是三根电线输出的电流一般要差不多大,如果悬殊一大就出现不平衡了,这时候就会出现如下情况:

Since the electricity output by the coking generator set is three-phase and four wire, that is, the output current of the three wires is generally about large. If there is a large difference, there will be imbalance. At this time, the following situations will occur:

1.发电机组输出功率下降,达不到用户的功率要求

1. The output power of the generator set decreases and fails to meet the power requirements of the user

2.三相电压不对称，使发电机组中性点电位产生位移

2. The three-phase voltage is asymmetric, causing the neutral point potential of the generator set to shift

3.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

3. If the neutral current is too large, the operating temperature of the distribution transformer will rise, and the transformer will be burned out in serious cases

4.使有的相电压高，另外的相电压降低

4. Make some phase voltages higher and the other phase voltages lower

5.烧坏发电机,影响正常供电

5. Burn out the generator and affect the normal power supply

所以,焦化发电机组使用中一定要注意,不能三相不平衡,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.

Therefore, attention must be paid to the three-phase imbalance during the use of coking generator set. If there is no way to change its output power, only the wiring mode can be changed frequently to prevent damage to the generator set
