        瓦斯發(fā)電機出現電磁干擾故障怎么辦?

        瓦斯發(fā)電機組的系統整體而言,火花塞點(diǎn)火電纜線(xiàn)內的交流電流等形成的電磁干擾是主要的干擾源。由干發(fā)電機組作環(huán)境的特殊性,在這些場(chǎng)合中要想避免經(jīng)常發(fā)生的較強的電磁干擾幾乎是不可能的。盡管新型的發(fā)電機組針對電磁干擾問(wèn)題采取了很多措施,也無(wú)法忽視此類(lèi)隱患并且由于工作場(chǎng)合中的條件的限制或者人為的疏忽如調試不當,也增大了此類(lèi)故障發(fā)生的概率。
        As for the whole system of the gas generator set, the electromagnetic interference caused by the AC current in the spark plug ignition cable is the main interference source. Due to the particularity of the dry generator set as the environment, it is almost impossible to avoid the frequent strong electromagnetic interference in these occasions. Although the new generation unit has taken many measures to solve the problem of electromagnetic interference, it can not ignore such hidden dangers and the probability of such failures is also increased due to the limitations of conditions in the workplace or human negligence, such as improper commissioning.
        例如某臺發(fā)電機組在并網(wǎng)后,正常運轉一段時(shí)間,之后發(fā)生了故障當該機組負荷<300kW時(shí),機組運行平穩;但是當負荷>300kW時(shí),大范圍的負荷擺動(dòng)出現了。機組人員進(jìn)行了脫網(wǎng)操作,在沒(méi)有負荷的情況下,發(fā)電機組的運行又趨于正常。這種故陪的迷惑性很大,因為先想到的原因是兩種:
        For example, a generator unit operates normally for a period of time after grid connection, and then fails. When the unit load is less than 300kW, the unit operates smoothly; However, when the load is more than 300kW, a wide range of load swing occurs. The crew carried out the off-grid operation, and the operation of the generator set tended to be normal again without load. This kind of reason is very confusing, because there are two reasons to think of first:
        (1)發(fā)電機的勵磁系統出現問(wèn)題;(2)發(fā)動(dòng)機帶負荷能力下降。
        (1) The excitation system of the generator has problems; (2) The load capacity of the engine decreases.
        錯誤的判斷耗費了工作人員大量的時(shí)間和精力,而問(wèn)題一直沒(méi)有解決。后來(lái)在做會(huì )面機檢時(shí)發(fā)現信號線(xiàn)中的一根線(xiàn)與屏蔽層短路,并且屏蔽線(xiàn)的接線(xiàn)處理上存在一定的問(wèn)題。更換該屏蔽線(xiàn)后再做測試,機組正常運轉。
        The wrong judgment consumes a lot of time and energy of the staff, and the problem has not been solved. Later, during the meeting machine inspection, it was found that one of the signal wires was short-circuited with the shielding layer, and there was a certain problem in the wiring processing of the shielding wire. After replacing the shielded wire, conduct the test, and the unit operates normally.
        在機檢的后期階段發(fā)現,該機組在布線(xiàn)時(shí)出現錯置,將信號線(xiàn)與發(fā)電機組的輸出電纜敷設在一起,并且相互纏繞,這就是干擾產(chǎn)生的真正原因。當信號線(xiàn)的屏蔽層性能良好并且接線(xiàn)方式也正確時(shí),可以正常屏蔽干擾信號,發(fā)電機組運轉正常而當屏蔽層失效時(shí),干擾信號就會(huì )帶來(lái)嚴重的影響。
        In the later stage of the machine inspection, it was found that the unit was wrongly wired, and the signal line and the output cable of the generator set were laid together and intertwined, which is the real reason for the interference. When the shielding layer of the signal line has good performance and the wiring mode is correct, the interference signal can be shielded normally, and the generator set operates normally. When the shielding layer fails, the interference signal will bring serious impact.
        瓦斯發(fā)電機組
        建議在安裝發(fā)電機組的施工過(guò)程中,須將信號電纜與電流電纜分開(kāi)敷設,以避免產(chǎn)生電磁干擾。信號干擾帶來(lái)的影響通常比較隱蔽,只有在特定情況下才會(huì )表現出來(lái),正是由于這種隱蔽性,經(jīng)常迷惑工作人員,給安裝和調試I作帶來(lái)很大的困難。只有正確判斷信號干擾帶來(lái)的燃氣發(fā)電機組異常表現,才可以正確的排除相應的故障。
        It is suggested that the signal cable and the current cable should be laid separately during the construction process of installing the generator set to avoid electromagnetic interference. The influence of signal interference is usually hidden and can only be shown under specific circumstances. It is precisely because of this concealment that it often confuses the staff and brings great difficulties to the installation and commissioning of the work. Only by correctly judging the abnormal performance of the gas generator unit caused by signal interference can the corresponding fault be correctly eliminated.
        在故障發(fā)生時(shí),切忌盲目猜測,應從故障現象分析內在原因,結合設備運轉原理進(jìn)行分析,由表及里,先易后難。如果條件允許盡可能的在機組運行中判斷問(wèn)題所在,盡量避免停機檢修,因為故障現象可能隨著(zhù)設備的停轉而消失,從而增大了排查故障的困難。更多相關(guān)內容就來(lái)我們網(wǎng)站http://m.elmasticar.com進(jìn)行咨詢(xún)了解吧!
        When a fault occurs, it is not allowed to guess blindly. The internal causes should be analyzed from the fault phenomenon and combined with the operation principle of the equipment. If conditions permit, try to determine the problem during the unit operation and avoid shutdown for maintenance as much as possible, because the fault phenomenon may disappear with the equipment shutdown, thus increasing the difficulty of troubleshooting.
