Ikirere gishyushye
-
Uyu mwaka, ibintu bya El Niño birashobora kubaho, cyangwa icyi gishyushye cyane mumateka kizatangira, kizazana ibibazo bikomeye kumashanyarazi.
1.1 Ingaruka yubushyuhe bwo hejuru kubigize
Ubushyuhe bukabije buzagabanya imikorere nubuzima bwibigize, nka inductors, capacitori ya electrolytike, modules yingufu, nibindi.
Inductance:Ku bushyuhe bwo hejuru, inductance iroroshye kwiyuzuzamo, kandi inductance yuzuye izagabanuka, bivamo kwiyongera kwagaciro keza kumashanyarazi akora, no kwangiza ibikoresho byamashanyarazi kubera kurenza urugero.
Ubushobozi:Ku mashanyarazi ya electrolytike, igihe cyo kubaho cya capacitori ya electrolytike kigabanukaho kimwe cya kabiri mugihe ubushyuhe bwibidukikije buzamutse kuri 10 ° C. Ububiko bwa aluminium electrolytike muri rusange bukoresha ubushyuhe bwa -25 ~ + 105 ° C, naho ubushobozi bwa firime bukoresha ubushyuhe bwa -40 ~ + 105 ° C. Kubwibyo, inverter ntoya akenshi ikoresha ubushobozi bwa firime kugirango ihindure imiterere ihindagurika nubushyuhe bwo hejuru.
Ubuzima bwa capacator ku bushyuhe butandukanye
Module yingufu:Ubushyuhe buri hejuru, niko ubushyuhe bwo guhuza ubushyuhe bwa chip mugihe module ikora ikora, bigatuma module itwara ubushyuhe bwinshi kandi bigabanya cyane ubuzima bwa serivisi. Ubushyuhe bumaze kurenga imipaka yubushyuhe, bizatera ubushyuhe bwumuriro wa module.
1.2 Ingero zo gukwirakwiza ubushyuhe
Inverter irashobora gukorera hanze kuri 45 ° C cyangwa ubushyuhe burenze. Igishushanyo mbonera cyo gukwirakwiza inverter nuburyo bwingenzi bwo kwemeza imikorere ihamye, itekanye kandi yizewe ya buri kintu cya elegitoroniki mubicuruzwa mubushyuhe bwakazi. Ubushyuhe bwo guhunika bwa inverter ni inductor yongerera imbaraga, inductor ya inverter, na module ya IGBT, kandi ubushyuhe bukwirakwizwa binyuze mumashanyarazi yo hanze hamwe nubushyuhe bwinyuma. Ibikurikira nubushyuhe bwo kugabanya umurongo wa GW50KS-MT:
Ubushyuhe bwa Inverter kuzamuka no kugwa kumurongo
1.3 Kubaka ingamba zo kurwanya ubushyuhe bwo hejuru
Ku gisenge cy'inganda, ubusanzwe ubushyuhe buri hejuru kurenza ubw'ubutaka. Kugirango wirinde ko inverter idahura nizuba ryizuba, inverter isanzwe ishyirwa ahantu h'igicucu cyangwa hongeweho urujijo hejuru ya inverter. Twabibutsa ko umwanya wo gukora no kubungabunga ugomba kubikwa aho umuyaga wa inverter winjira ugasohokera umuyaga numuyaga wo hanze. Ibikurikira ni inverter ifite ibumoso niburyo bwo gufata umwuka no gusohoka. Birakenewe kubika umwanya uhagije kumpande zombi za inverter, no kubika intera ikwiye hagati yizuba ryizuba no hejuru ya inverter.

Tibihe by'imvura y'amahindu
-
Inkuba n'imvura y'amahindu mu cyi.
2.1 Ingero zumurabyo ningamba zo gukingira imvura
Ingamba zo gukingira inkuba:Impande za AC na DC za inverter zifite ibikoresho byo murwego rwohejuru birinda inkuba, kandi imibonano yumye ifite imishwarara yo gukingira inkuba, ibyo bikaba byoroheye inyuma kugirango umenye ibihe byihariye byo kurinda inkuba.
Ingero zidahindura imvura ningamba zo kurwanya ruswa:Inverter ifata urwego rwo hejuru rwo kurinda IP66 hamwe na C4 & C5 murwego rwo kurwanya ruswa kugirango barebe ko inverter ikomeza gukora munsi yimvura nyinshi.
Guhuza ibinyoma bihuza fotovoltaque, kwinjira mumazi nyuma yumugozi wangiritse, bikavamo umuzunguruko mugufi kuruhande rwa DC cyangwa kumeneka kubutaka, bigatuma inverter ihagarara. Kubwibyo, DC arc yo kumenya imikorere ya inverter nayo ni ngombwa cyane.
2.2 Muri rusange ingamba zo kurinda inkuba (kubaka)
Kora akazi keza ka sisitemu yubutaka, harimo ibice byimbere hamwe na inverters.
Ingamba zo gukingira inkuba kumurongo wizuba na inverter
Impeshyi yimvura irashobora kandi gutera urumamfu gukura no kugicucu. Iyo amazi yimvura yogeje ibice, biroroshye gutera umukungugu kumpande yibigize, bizagira ingaruka kumirimo ikurikira.
Kora akazi keza mugusuzuma sisitemu, buri gihe ugenzure uburyo bwokwirinda hamwe n’amazi adahuza amazi ya fotokoltaque ninsinga, urebe niba insinga zashizwemo igice cyamazi yimvura, kandi niba hari gusaza no gucika mumashanyarazi.
Amashanyarazi ya Photovoltaque ni ibihe byose bitanga ingufu. Ubushyuhe bwinshi ninkuba mu mpeshyi byazanye imbogamizi zikomeye ku mikorere no gufata neza amashanyarazi y’amashanyarazi. Uhujije inverter hamwe nigishushanyo mbonera cy’amashanyarazi muri rusange, Xiaogu atanga ibitekerezo kubyerekeye kubaka, gukora no kubungabunga, kandi yizera ko bizafasha buri wese.
