Ka lebaka la litlhoko tsa tlhahiso, ho na le palo e kholo ea meroalo ea pompo indastering ea petrochemical, 'me meroalo e mengata ea pompo e na le li-converter tsa maqhubu.Palo e kholo ea ts'ebeliso ea li-converter tsa maqhubu e eketsa haholo litaba tsa harmonic tsa sistimi ea kabo indastering ea petrochemical.Hajoale, lihokelo tse ngata tsa li-rectifier tsa li-frequency converter ke ts'ebeliso ea 6 pulse rectifier ho fetolela AC ho DC.Ka hona, li-harmonics tse hlahisoang haholo ke li-harmonics tsa 5, 7 le 11.
1. Tlhahlobo ea litšobotsi tsa mojaro indastering ea oli
Ho feta 85% ea matla a matla ka har'a marang-rang a indasteri ea oli ke mojaro o kenang, joalo ka lipompo tse fapaneng tsa oli, li-motors joalo-joalo.Lilemong tsa morao tjena, kaha sebaka sa oli se hlahisitse litlhoko tse phahameng tsa ho baballa matla, lihlopha tse ngata li amohetse lisebelisoa tse ngata tsa ho boloka matla.Ka lebaka la phello ea eona e hlakileng ea ho boloka matla, ho lokisoa habonolo, tlhokomelo e bonolo le marang-rang, converter ea maqhubu e 'nile ea sebelisoa haholo ho sebelisoa ha oli.Pompo, pompo, pompo ea ho theoha le pompo e kopanyang seteisheneng sa tlhahiso ea oli li khannoa ke converter frequency, empa converter frequency e tla hlahisa palo e kholo ea li-harmonics ho kena-kenana le mojaro le lisebelisoa tsa eona tse haufi, 'me li-harmonics le tsona li tla hlahisa li-harmonics tse ngata. ama marang-rang a matla a sechaba ka mohala oa motlakase o kenang.
2. Kotsi ea li-harmonics ho marang-rang a matla a tšimo ea oli
1) Harmonics e ama ts'ebetso e tsitsitseng ea marang-rang a matla a oli le ho fokotsa boleng ba phepelo ea matla a marang-rang a matla a sebaka sa oli.
2) Harmonics e eketsa matla a tahlehelo ea capacitor, e khutsufatsa bophelo ba tšebeletso ea capacitor ea matla, 'me tabeng ea li-harmonics tse tebileng, e tla boela e etse hore capacitor e be leqhubu, ho senyeha kapa ho phatloha.Harmonics e ka boela ea eketsa tahlehelo ea matla ea transformer.
3) Harmonics e tla etsa hore ho lahleheloa ke matla a motlakase ho eketseha, ho baka ho chesa haholo, ho hlahisa ho sisinyeha ha mechine, lerata le ho feta ha harmonic, e leng ho tla khutsufatsa bophelo ba lisebelisoa, esita le ho senya maemong a tebileng;Harmonics e tla baka ho se sebetse hantle ha tšireletso kapa ketso ea ho hana;Li-harmonics tsamaisong ea matla li kopantsoe le sistimi e fokolang ea hona joale ka ho kenella ka motlakase, ho kenella ka motlakase le ho tsamaisa, tse tla baka tšitiso ho sistimi e fokolang ea hajoale.
Ka tšebeliso e pharaletseng ea mochine oa motlakase tsamaisong ea ente ea metsi tšimong ea oli, ha e rarolle feela mathata a phetoho ea khatello ea ente ea metsi e tloaelehileng, tšebeliso e phahameng ea matla le ts'ebetso e tlaase, empa hape e tlisa keketseho ea litaba tsa harmonic ho grid ea matla.Ho ba teng ha palo e kholo ea li-harmonics ho sokela ho ts'epahala le ts'ireletso ea sistimi ea phepelo ea motlakase.E le ho felisa kotsi e bakoang ke li-harmonics, tšebeliso ea lihlahisoa, ho ntlafatsa boleng ba phepelo ea matla a marang-rang a matla, ho netefatsa tlhahiso e tloaelehileng.
Motlakase oa Noker(/ about-us/) sefahla se sebetsang sa harmonicka thekenoloji ea morao-rao ea 3-level IGBT, ke sehlahisoa se loketseng sa taolo ea harmonic.Tšehetso leha e le efe, ikopanye le rona ka bolokolohi.Re tla u fa tharollo e hlophisitsoeng.
