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?

由于焦化發(fā)電機組組輸出的電是三相四線(xiàn)的,就是三根電線(xiàn)輸出的電流一般要差不多大,如果懸殊一大就出現不平衡了,這時(shí)候就會(huì )出現如下情況:

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.發(fā)電機組輸出功率下降,達不到用戶(hù)的功率要求

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

2.三相電壓不對稱(chēng)，使發(fā)電機組中性點(diǎn)電位產(chǎn)生位移

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

3.中性電流過(guò)大，使配電變壓器運行溫度升高，嚴重時(shí)會(huì )將變壓器燒壞

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.使有的相電壓高，另外的相電壓降低

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

5.燒壞發(fā)電機,影響正常供電

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

所以,焦化發(fā)電機組使用中一定要注意,不能三相不平衡,如果沒(méi)有辦法改變它的輸出功率,只有經(jīng)常掉換接線(xiàn)方式,以防造成發(fā)電機組的損壞.

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
