Filter na DC-link capacitors ni ibice by'ingenzi bya sisitemu yo guhindura amashanyarazi

Ibisobanuro bigufi:

Capacitors za polypropylene zifite ibyuma byinshi bya crystalline ni zo zikoreshwa cyane mu gutunganya DC Filter, kubika ingufu n'ibindi bisa nabyo mu kinyejana cya 21.

Filter na DC-link capacitors ni ibice by'ingenzi bya sisitemu yo guhindura amashanyarazi,
Umutanga Capacitor yihariye,

Amakuru ya tekiniki

Ingano y'ubushyuhe bwo gukora	Ubushyuhe bwo gukora cyane, Hejuru hejuru ntarengwa: + 85℃ Ubushyuhe bwo mu cyiciro cyo hejuru: +70℃ Ubushyuhe bwo mu cyiciro kiri hasi: -40℃

Ikiranga

1. Ubwoko bwa PP Box, ifu y'umusemburo wumye;
2. Inkono z'umuringa / ibyuma bipfundikiye, imiterere y'igipfundikizo cya pulasitiki ishyushye, byoroshye kuyishyiraho;
3. Ubushobozi bunini, ingano nto;
4. Kurwanya ingufu nyinshi z'amashanyarazi, hamwe no kwivura ubwabyo;
5. Umugezi ushyushye cyane, ubushobozi bwo kwihanganira dv / dt buri hejuru.
Kimwe n'ibindi bicuruzwa bya CRE, capacitor y'uruhererekane ifite icyemezo cya UL kandi yapimwe 100% by'ubushyuhe.

Porogaramu

1. Ikoreshwa cyane muri DC-Link circuit mu kuyungurura ububiko bw'ingufu;
2. Ishobora gusimbura capacitors za electrolytic, gukora neza no kuramba.
3. Inverter ya Pv, converter y'ingufu z'umuyaga; Ubwoko bwose bw'ingufu zihindura frequency na inverter; Imodoka z'amashanyarazi n'izivanze; SVG, ibikoresho bya SVC n'ubundi bwoko bw'imicungire myiza y'ingufu.

Icyizere cy'ubuzima

Igishushanyo mbonera

Gusaba kuzigama ingufu no kubona amasoko ashobora kuvugururwa bitera iterambere ry’ibicuruzwa nk’ibinyabiziga bikoresha amashanyarazi, imashini zihindura amashanyarazi za PV, imashini zitanga ingufu z’umuyaga. Ibi bicuruzwa bisaba ko inverter ya DC kuva kuri AC ikora kugira ngo sisitemu ikore neza. Imashini ziyungurura na DC-link capacitors ni ibice by’ingenzi by’ingenzi kuri sisitemu y’amashanyarazi bitanga inkunga yo kongera ingufu hakoreshejwe ingufu nyinshi n’imigezi ihindagurika.

Nk'ikigo gishya gifite ikoranabuhanga rigezweho, CRE ifite itsinda ry'abahanga mu bushakashatsi no mu nganda rikora ibikoresho by'amashanyarazi, kandi yashinze ibigo by'ubushakashatsi no mu nganda by'amashanyarazi hamwe n'ibigo by'ubushakashatsi bizwi ku rwego mpuzamahanga. Kugeza ubu, CRE ifite ibihangano birenga 40 by'ubuhanga n'ipatanti z'icyitegererezo cy'ibikoresho kandi yagize uruhare mu iterambere ry'amahame 10 y'igihugu n'inganda, byemejwe na ISO-9001, IATF16949, ISO14001/45001, na UL. Twiyemeje guteza imbere abafatanyabikorwa benshi mu bucuruzi kugira ngo dutere imbere udushya mu by'amashanyarazi.

Ibicuruzwa bikunzwe bya CRE:
① Capacitor ya DC-link
② Capacitor y'icyuma gishyushya AC
③ Ububiko bw'ingufu / Kapateri y'ingufu
④ Kwirengagiza ibya IGBT
⑤ Capacitor y'ikirahuri
⑥ Capacitor ikonjeshejwe n'amazi

Ibanjirije iyi: Capacitor ya filime yihariye ikoreshwa mu bikoresho by'ikoranabuhanga

Ibikurikira: Filter na DC-link capacitors ni ibice by'ingenzi bya sisitemu yo guhindura amashanyarazi
