Isici

1. PP Box-uhlobo, eyomile resin ukumnika;
2. Copper nut / screw lead, plastic insulated isembozo positioning, ukufakwa lula;
3. Umthamo omkhulu, usayizi omncane;
4. Ukumelana ne-voltage ephezulu, ngokuziphilisa;
5. High ripple current, high dv/dt ukumelana nekhono.
Njengeminye imikhiqizo ye-CRE, i-capacitor yochungechunge inesitifiketi se-UL futhi ihlolwe ukushiswa okungu-100%.

Isicelo

1. Isetshenziswa kakhulu kusekethe ye-DC-Link yokuhlunga isitoreji samandla;
2. Ingashintsha ama-electrolytic capacitor, ukusebenza okungcono nempilo ende.
3. I-Pv inverter, isiguquli samandla omoya;Zonke izinhlobo ze-frequency converter kanye ne-inverter power supply;Izimoto ezihlanzekile zikagesi ne-hybrid; ama-SVG, amadivayisi we-SVC nezinye izinhlobo zokuphathwa kwekhwalithi yamandla.

Iminyaka yokuphila

Umdwebo wohlaka

Isidingo sokonga amandla kanye nemithombo evuselelekayo sikhuthaza ukuthuthukiswa kwemikhiqizo efana nezimoto zikagesi, iziguquli ze-PV, iziphehla amandla omoya.Le mikhiqizo idinga isiguquli se-DC kuya ku-AC ukuze ibone uhlelo lokusebenza.Ama-Filter kanye nama-DC-link capacitor yizici ezibalulekile zokungenzi lutho zesistimu yamandla ezihlinzeka ngokusekela isidingo samandla akhulayo anamandla kagesi aphezulu kanye nama-ripple currents.

Njengebhizinisi elikhulayo lobuchwepheshe obuphezulu, i-CRE ine-R&D engaphambili kanye nethimba elikhiqiza ama-capacitor amafilimu kagesi, futhi yasungula izikhungo zobunjiniyela be-R&D ye-electronics enezikhungo zocwaningo ezidumile emhlabeni wonke.Kuze kube manje, i-CRE ineziqalo ezingaphezu kuka-40 namalungelo obunikazi emodeli yensiza futhi ibambe iqhaza ekuthuthukisweni kwamazinga ayi-10 kazwelonke nawemboni, agunyazwe nge-ISO-9001, IATF16949, ISO14001/45001, kanye ne-UL.Sinikezela ukuthuthukisa ozakwethu abaningi bebhizinisi ukuze baqhube ukuqanjwa kabusha kwamandla.

Imikhiqizo edumile ye-CRE:
① DC-link capacitor
② I-AC filter capacitor
③ Isitoreji samandla / I-Pulse capacitor
④ I-IGBT snubber
⑤ I-resonance capacitor
⑥ I-capacitor epholile yamanzi

Okwedlule: I-Custom Film capacitor ye-electronics
