High voltage soft start state txee yog tsim nyog rau (3 ~ 10kV) squirrel tawb asynchronous motor pib thiab nres tswj thiab tiv thaiv. Qhov zoo tshaj plaws anti-parallel thyristor Cheebtsam thiab cov khoom siv hluav taws xob tswj kev sib txuas ntawm stator winding ntawm lub siab voltage lub cev muaj zog thiab cov khoom siv hluav taws xob. Thaum lub cev muaj zog pib, raws li ib qho kev cai lij choj (xws li qhov tsis tu ncua tam sim no lossis qhov hluav taws xob qhov hluav taws xob) tswj cov ntses ntawm cov khoom sib txuas, thiab tsis tu ncua hloov cov tswv yim ntawm stator zaum kawg pab pawg ntawm lub cev muaj zog los ntawm lub siab mus rau tag nrho lub siab, tom qab pib. ua tiav, lub bypass contactor yog kos. Nws muaj kev ua haujlwm ntawm kev tiv thaiv kev txhaum xws li kev hlais, luv luv pib, ncov overcurrent, thiab lwm yam. Siv nws tuaj yeem zam qhov teeb meem cuam tshuam los ntawm lub cev muaj zog ntau dhau los pib tam sim no rau hauv daim phiaj hluav taws xob, thiab feem ntau tuaj yeem siv lub zog siab zog. nyob rau hauv kev txwv fais fab tuag muaj peev xwm thiab txuas ntxiv nws lub neej kev pab cuam. Tsis tas li ntawd, High voltage soft start state txee kuj muaj "mos nres" muaj nuj nqi, thaum muag muag, lub cev muaj zog stator winding voltage yuav smoothly txo, yog li zam lub stagnation ntawm cov khoom, uas yog ib qho tseem ceeb rau lub twj tso kua mis (tuaj yeem zam. cov nyhuv ntawm dej rauj) los yog siv conveyor.
1. Me me thiab ua haujlwm puv
Lub txee ntoo integrates high-voltage solid-state soft-start txee, high-voltage hloov txee, thiab bypass txee rau hauv ib lub txee integrated. Nws yog qhov me me. Piv nrog rau qhov sib cais high-voltage hloov txee thiab lub txee qhia,
Qhov chaw pib txee yog txo los ntawm ib nrab, thiab nws kuj muaj lub luag haujlwm ntawm kev pib muag muag, muag muag, hloov txee thiab bypass txee.
2. Qhov pib tam sim no me me thiab lub zog txuag hluav taws xob tseem ceeb
Lub nruab nrab- thiab high-voltage hloov khoom-lub xeev soft-start integrated txee kho qhov voltage los ntawm kev hloov lub conduction lub kaum sab xis ntawm lub thyristor, tsis muaj zog poob thiab pib tam sim no.
Me me, 2.5 ~ 3.5 npaug ntawm qhov ntsuas tam sim no.
3. Muaj peev xwm tiv thaiv kev cuam tshuam, yoog raws ntau qhov chaw siv
Lub txee no yog tsim los nrog tshwj xeeb tiv thaiv-capacitance absorption circuit, uas muaj zog tiv thaiv kev cuam tshuam. Cov khoom ua tau zoo yog ruaj khov, tsis cuam tshuam los ntawm qhov kub thiab txias ntawm thaj chaw, thiab tuaj yeem pib nquag.
4. Kev tiv thaiv kev ua haujlwm zoo thiab kev ruaj ntseg siab
Nws muaj kev tiv thaiv txhaum cai xws li overload, theem poob, thiab pib peak overcurrent. Qhov pib tsis yog xaiv tau, kho tau thiab tswj tau.
5. Kev tu-dawb, txuag nqi
Tus qauv tsim tsis muaj kev saib xyuas txo cov kab hluav taws xob ntawm cov khoom siv hluav taws xob siab thiab cov khoom muag muag. Tsis muaj lwm yam kev kho yuav tsum tau tom qab muab tso rau hauv kev siv, uas tuaj yeem txuag tau nyiaj ntau hauv cov nqi kho.
