眾所周知，為了延長發(fā)電機組的壽命，需要及時修復發(fā)電機組的故障。但是，有些用戶認為某些小故障不會影響設備的使用，因此在設備出現(xiàn)故障之前將其忽略，這是非常錯誤的。本文，瓦斯發(fā)電機組小編正在談論著來不及修理發(fā)電機組的危害。

As we all know, in order to prolong the life of generator set, it is necessary to repair the fault of generator set in time. However, some users think that some minor failures will not affect the use of the equipment, so it is very wrong to ignore them before the equipment fails. In this article, the gas generator unit editor is talking about the harm of not having time to repair the generator unit.

1、如果發(fā)電機組修理不及時，定子繞組的匝數會短路，短路電壓會產生電路電流，這可能會使匝間短路發(fā)展為單相接地短路和相間短路。如果定子線圈多相短路，會給單元帶來很大的危害，短路電流會導致單元燒損。

1. If the generator set is not repaired in time, the turns of the stator winding will be short circuited, and the short circuit voltage will generate circuit current, which may cause the turn to turn short circuit to develop into single-phase grounding short circuit and phase to phase short circuit. If the stator coil is polyphase short circuited, it will bring great harm to the unit, and the short circuit current will lead to unit burning.

2、發(fā)電機組若不立即修復，勵磁電流會急劇下降或消失，發(fā)電機從系統(tǒng)中吸收大量的無功功率，發(fā)電機從同步運行轉化開始異步運行，系統(tǒng)電壓下降，系統(tǒng)崩潰。

2. If the generator set is not repaired immediately, the excitation current will drop sharply or disappear, the generator will absorb a lot of reactive power from the system, the generator will start asynchronous operation from synchronous operation, the system voltage will drop, and the system will collapse.

3、如果發(fā)電機組不立即修理，勵磁電路接地。發(fā)電機勵磁電路：1點接地和2點接地有2種接地。一般來說，勵磁電路稍微接地時，對發(fā)電機沒有嚴重危害。但是，如果發(fā)電機修理不及時，2點接地，轉子的磁通、平衡被破壞，引起發(fā)電機的強烈振動，終有可能燒壞轉子線圈。

3. If the generator set is not repaired immediately, the excitation circuit is grounded. Generator excitation circuit: there are two kinds of grounding for 1-point grounding and 2-point grounding. Generally speaking, when the excitation circuit is slightly grounded, there is no serious harm to the generator. However, if the generator is not repaired in time and the two points are grounded, the magnetic flux and balance of the rotor will be damaged, causing strong vibration of the generator, which may eventually burn out the rotor coil.

4、如果發(fā)電機組不立即修理，機組將變?yōu)檫^電壓。發(fā)電機在運行中突然失去負載時，如果發(fā)電機不能立即恢復，由于調速系統(tǒng)的較大慣性會產生過電壓，發(fā)電機組的絕緣層可能被破壞。

4. If the generator set is not repaired immediately, the generator set will become overvoltage. When the generator suddenly loses load during operation, if the generator cannot be recovered immediately, overvoltage will be generated due to the large inertia of the speed governing system, and the insulation layer of the generator set may be damaged.

5、如果發(fā)電機組來不及的話，機組將超負荷。發(fā)電機過載，意味著發(fā)電機的運轉超過了額定容量。如果發(fā)電機不立即修理，短時間的過負荷運轉會使發(fā)電機定子線圈的溫度上升，絕緣部分的劣化會加速，發(fā)電機的壽命會縮短。如果長時間過載，發(fā)電機定子線圈燒壞，終發(fā)電機可能無法發(fā)電。

5. If the generator set is too late, the unit will be overloaded. Generator overload means that the generator operates beyond the rated capacity. If the generator is not repaired immediately, the temperature of generator stator coil will rise due to short-term overload operation, the deterioration of insulation will accelerate, and the life of generator will be shortened. If the overload lasts for a long time and the generator stator coil is burnt, the final generator may not be able to generate electricity.

6、發(fā)電機組如果不立即修理，定子會通過過電流。定子的過電流通常是由外部短路或系統(tǒng)振蕩引起的。如果發(fā)電機不及時修理，發(fā)電機的定子溫度會稍微上升，繞組絕緣部分的老化會加速嚴重的情況下，可能會引起其他的錯誤。為了防止上述故障的發(fā)生，用戶在發(fā)現(xiàn)故障后立即停止機械，不管故障大小，在投入使用前須修理設備。此外，柴油發(fā)電單元具備相應的保護裝置，能夠更好地保護單元。

6. If the generator set is not repaired immediately, the stator will pass over current. Overcurrent of stator is usually caused by external short circuit or system oscillation. If the generator is not repaired in time, the stator temperature of the generator will rise slightly, and the aging of the winding insulation will accelerate seriously, which may cause other errors. In order to prevent the occurrence of the above faults, the user shall stop the machine immediately after finding the fault, regardless of the size of the fault, and must repair the equipment before putting it into use. In addition, the diesel power generation unit is equipped with corresponding protective devices, which can better protect the unit.
