Imashini ya Sine

Ibisobanuro bigufi:

Hindura moteri ya PWM yerekana moteri kumurongo wa sine woroheje hamwe na voltage nkeya isigaye, birinda kwangirika kwa moteri.Mugabanye phenomenon ya resonance iterwa na capacitance yagabanijwe no kugabura inductance bitewe nuburebure bwumugozi, kurandura moteri ya moteri iterwa na dv / dt nyinshi, kurandura ibyangiritse hakiri kare moteri yatewe nigihombo cya eddy, kandi akayunguruzo kagabanya kumvikana. urusaku rwa moteri.

(1) Ingero zavuzwe haruguru nibicuruzwa byacu bisanzwe, nibindi bisobanuro birashobora gutegurwa ukurikije ibyo abakiriya bakeneye;
(2) Niba ukeneye ibipimo byihariye nibiciro mugihe cyo gutoranya icyitegererezo, nyamuneka ubaze ubucuruzi bwacu;
(3) Kubipimo byihariye n'ibipimo, nyamuneka reba ibisobanuro n'ibishushanyo byatanzwe na sosiyete yacu kugirango ubone ibisobanuro birambuye.
Sine umurongo wo kuyungurura ibitekerezo
1. Nyuma yo gukoresha akayunguruzo ka sine, ubushobozi bwimitwaro ya inverter izaba munsi yubushobozi bwimitwaro yumuriro wagabanijwe wa moteri.
2. Sine wave filter izatera igipimo runaka cya voltage igabanuka mumashanyarazi.Mugihe cyibanze cya 50Hz, kugabanuka kwa voltage ni 10%.Ikigereranyo cyacyo kijyanye no guhindura inshuro zifatizo.
3. Akayunguruzo kayungurura umubare munini wibintu byinshi byateganijwe bihuza murwego rwo kuyungurura umuraba wa PWM mumurongo wa sine, bityo inverter izaba ifite ibyerekeranye nibisohoka byagenwe byimbere mugihe inyungurura nta mutwaro.
4. Nyuma yo gukoresha akayunguruzo ka sine, uburebure bwinsinga ihuza ni 300m-1000m
5. Kubisanzwe bya sine wave filter yibicuruzwa, inverter isohoka itwara inshuro inshuro 4-8KHz.Niba inshuro zitwara ibyifuzo byawe bitari murwego, nyamuneka sobanurira isosiyete.Bitabaye ibyo, ikoreshwa rya filteri rizagira ingaruka, kandi akayunguruzo kazatwikwa mugihe gikomeye.
6. Akayunguruzo kagomba kwemeza guhumeka neza mugihe gakoreshwa.
Sine wave filter muyunguruzi ingaruka igishushanyo

Ibipimo bya tekiniki

Ibiranga
Imiterere-yimikorere ihanitse yimikorere iremewe, kandi umurongo wa aluminiyumu urasohoka, ufite DC ntoya irwanya imbaraga, imbaraga zikomeye zo kurwanya amashanyarazi, hamwe nubushobozi buke bwigihe gito;ibikoresho-byinshi byo mu Buyapani byo mu rwego rwo hejuru byifashishwa mu kwemeza ko ibicuruzwa bishobora gukomeza kubungabungwa mu bihe bikomeye byakazi.Imikorere yizewe;reaction ifite imbaraga za dielectric nyinshi kandi irashobora kwihanganira ingaruka zikomeye za dv / dt.Imashini ifata inzira yo gutera akabariro, kandi urusaku rwumvikana ni ruto.
Ibipimo byibicuruzwa
Ikigereranyo cya voltage ikora: 380V / 690V 1140V 50Hz / 60Hz
Ikigereranyo gikora: 5A kugeza 1600A
Ubushyuhe bwibidukikije bukora: -25 ° C ~ 50 ° C.
Imbaraga za dielectric: intangiriro imwe ihinduranya 3000VAC / 50Hz / 5mA / 10S nta flashover isenyutse (ikizamini cyuruganda)
Kurwanya insulasiyo: 1000VDC irwanya insulation ≤ 100M
Urusaku rwa reaktor: munsi ya 80dB (igeragezwa nintera itambitse ya metero 1 uvuye kuri reaction)
Icyiciro cyo kurinda: IP00
Icyiciro cyo gukumira 2F cyangwa hejuru
Ibipimo byo gushyira mu bikorwa ibicuruzwa: GB19212.1-2008, GB19212.21-2007, 1094.6-2011.
