Onstabiele spanning in diesel Kragopwekkers is nie ideaal vir jou toerusting nie. Of jy die kragopwekker vir industriële of kommersiële toepassings gebruik, die kragtoevoer moet die meeste van die tyd stabiel wees. Maar af en toe, jy verwag probleme met spanningskommelings te ontstaan. Jy moet die oorsake en beskikbare oplossings identifiseer.
1. Onstabiele spanning in dieselopwekkers: Betekenis
Onstabiele spanning vind plaas wanneer die spanning van jou Diesel kragopwekker wissel. Die kragtoevoer in hierdie geval is nie eenvormig of glad nie. As gevolg van hierdie variasies, die toerusting kan misluk. Maar wat veroorsaak spanningskommelings? Swak kragopwekkerinstallasie sal waarskynlik prestasieprobleme tot gevolg hê.
Net so, verslete komponente, veral die alternator, kan die oorsaak wees. Ander perifere oorsake sluit in ongebalanseerde vragverspreiding en inkonsekwente enjinspoed. By seldsame geleenthede, kragopwekker uitset onstabiliteit kan weens 'n foutiewe spanningsreguleerder wees.
2. Oplossing vir die probleem van Onstabiele spanning in dieselopwekkers
Om probleme met die diesel kragopwekker aan te spreek, beide meganiese en elektriese faktore wat dit kan beïnvloed, moet geïdentifiseer word. 'n Mens moet hierdie faktore vooraf aanspreek voordat dit probleme veroorsaak. Sommige areas om waar te neem, sluit in behoorlike installasie en instandhouding. Ook, trek die bedrading vas, kalibreer dan die stelsel.
Mits daar geen oorlading is nie, goeie diesel kragopwekkers sal 'n konstante spanning verskaf aan alle toerusting wat aan die kragopwekker gekoppel is. Egter, dit is nie altyd die geval wanneer die kragopwekker faal nie. Buitendien, die eenheid sal nie 'n vaste spanning handhaaf nie as gevolg van swak diens.
2.1 Verbetering van installasie
'n Onbehoorlik geïnstalleerde kragopwekker sal 'n onstabiele stroom produseer wanneer dit aangedryf word. Ook, as dit los verbindings het, wanbelyning, of is nie geaard nie, dit mag dalk nie 'n toepaslike uitset lewer nie. Die beste manier om 'n konstante spanningstoevoer te verseker, is behoorlike installasie en instandhouding.
'n Stabiele fondament, aarding volgens die vervaardiger se vereistes, en bedrading is van die belangrikste oorwegings tydens installasie. Konstrukteurs en nywerhede benodig bykomende kenmerke in hul kragopwekkers. Die kragopwekker sal in 'n vibrerende omgewing werk en met optimale ventilasie om dieselfde spanning te onderhou.
By die installering van 'n kragopwekker vir hierdie doel, ons beveel aan dat u 'n professionele persoon aanstel om prestasie te verbeter en u eenheid se lewe te verleng.
2.2 Alternator herstel
Die alternator is die mees kritieke komponent in die dieselgenerator. So as foutief, die resultate sal 'n daling in die spanning wees. Kyk vir beskadigde laers; daarby, daar kan los terminale of gebreekte isolasie wees, wat waarskynlik kraglewering sal verminder. Dus, om teen spanningsveranderinge te isoleer, dit is nodig om hulle gereeld te monitor. As die alternator defekt is, herstel dit voordat die eenheid aangeskakel word. Dit help voorkom spanning fluktuasie kwessies wat die vrag kan beïnvloed. In toepassings waar die kragopwekker vir baie ure werk, maak alternator-diens deel van die instandhoudingsplan. Vervang verslete dele of gradeer die alternator gereeld op.
2.3 Enjinonderhoud
'n Bestendige rotasiespoed is 'n noodsaaklike faktor omdat dit bepaal kragopwekker uitset onstabiliteit. In sommige gevalle, onreëlmatige brandstoftoevoer en verslete inspuiters kan die spoed beïnvloed en onstabiele spanning veroorsaak. Verstopte filters en swak smering lei tot enjinskommelings, onstabiele spanning veroorsaak. Dus, gereelde enjinonderhoud kan die verskil maak.
Maak die filters skoon en vervang die olie gereeld. Daar is baie voordele verbonde aan behoorlike enjinversorging. Dit verminder brandstofverbruik en stel die kragopwekker in staat om 'n konstante spanning te verskaf. Dit hou ook die kragopwekker in 'n goeie toestand, laat dit toe om in die spitsvraag te voorsien.
2.4 Vragbestuur
Vragbestuur is een van die oorsake van spanning fluktuasie kwessies in kragopwekkers. Die meeste operateurs is geneig om die toerusting te oorlaai. Oorlading dwing die enjin om ver bo sy gegradeerde kapasiteit te werk. Ook, oormatige laai strem die enjin, lei tot 'n onstabiele elektriese toevoer. Die operateur moet dus nie die enjin oorlaai nie.
Hulle moet die vrag balanseer en verseker dat dit net 70–80 persent kapasiteit gebruik. Nog 'n waardevolle aspek van vragbestuur is die behoorlike ontplooiing van die kragopwekker. Industriële toepassings vereis swaardiens kragopwekkers omdat hulle vir lang tydperke werk. Aan die ander kant, 'n ligopwekker kan gebruik vind in RV's en mariene stelsels.
2.5 AVR-aanpassing
AVR staan vir outomatiese spanningsreguleerder. Hierdie toestel reguleer die spanningsuitset. Dit is 'n kritieke komponent wat help om spanningstabiliteit te handhaaf. As die AVR-stelsel oud is of die instellings verkeerd is, jy sal waarskynlik ervaar kragopwekker uitset onstabiliteit. Ook, foutiewe instellings maak dit moeilik vir die kragopwekker om die nominale spanning te handhaaf.
Jy kan probleme wat met AVR geassosieer word verminder of uitskakel deur hoëgehalte kragopwekkers met robuuste AVR-stelsels te koop. Net so, kontrolering en kalibrering van die AVR-stelsel waarborg dikwels konsekwente spanningsuitset.
