Uburinzi bwuzuye bw'ingufu ku buryo bwizewe

Muri iki gihe isi y’amashanyarazi ikomeje kwiyongera, kurinda ibikoresho imbaraga zikabije z’amashanyarazi ziterwa n’inkuba cyangwa ibikorwa byo guhinduranya ni ngombwa.Ibikoresho birinda indwara (SPD), harimo ubwoko bwa 1 n'ubwoko bwa 2, byagenewe kurinda sisitemu zawe z'amashanyarazi no gutuma imikorere idahagarara mu bidukikije bitandukanye by'amashanyarazi.

Ubwoko bwa 1 SPD - Uburinzi bukomeye ku nkuba z'inkuba

MUTAI'sUrukurikirane rwa T1SPD yakozwe kugira ngo ishobore guhangana n’ingufu nyinshi, cyane cyane izituruka ku nkuba zitaziguye. Yagenewe ibidukikije bikomeye nko mu nganda, sitasiyo nto, na sisitemu zo gukwirakwiza ingufu z’amashanyarazi mu bucuruzi.

Ibintu by'ingenzi by'ingenzi mu bya tekiniki:

• Umuvuduko wo gusohora ugereranyije n'uko uhagaze (8/20μs): Kugeza kuri 50kA

• Umuvuduko ntarengwa wo gusohora (8/20μs): Kugeza kuri 200kA

• Umuyoboro w'amashanyarazi (10/350μs): 15kA kugeza 50kA

• Urwego rwo Kurinda Voltage: ≤2.0kV / ≤3.0kV

• Igihe cyo Gusubiza: ≤100ns

• Ubushyuhe bwo gukora: -40℃ kugeza +80℃

• Ibikoresho: Nayiloni irinda umuriro

• Uburinzi bw'Injira: IP20

• Ubushobozi bwo gukoresha insinga: 6–35mm²

Itanga ingufu zidasanzwe, isubiza vuba, kandi ikaba ifite uburinzi bwo hejuru hamwe n’imbaraga zagutse zo gukoresha (220/385V).

Ubwoko bwa 2 SPD - Uburinzi bwa kabiri ku bikoresho by'amashanyarazi

ItsindaUrukurikirane rwa T2SPD itanga uburinzi bw'amashanyarazi bukenewe cyane ku bikoresho by'ikoranabuhanga byo mu ngo, mu bucuruzi no mu bikoresho by'ikoranabuhanga byoroshye. Yagenewe ingaruka z'inkuba zitaziguye no guhindagurika kw'amashanyarazi.

Ibintu by'ingenzi by'ingenzi mu bya tekiniki:

• Umuvuduko usanzwe wo gusohora (8/20μs): 5kA – 60kA

• Umuvuduko wo Kurekura Ukomeye: Kugeza kuri 100kA

• Urwego rwo Kurinda Voltage (Hejuru): Hafi 1.5kV

• Urugendo rw'ingufu z'amashanyarazi: 275V–440V

• Umuyoboro w'amazi usohoka: <20µA

• Igihe cyo Gusubiza: <25ns

Uru ruhererekane rwerekana uburyo bwo kurinda neza sisitemu zifite voltage nkeya binyuze mu gufunga amashanyarazi mbere yuko agera ku mitwaro ikomeye.

Ibisabwa mu gushyiraho

• Gushyiraho: Gari ya moshi isanzwe ya 35mm DIN

• Guhuza: Insinga z'umuringa zifite ubuziranenge bwo hejuru, uburebure ntarengwa bwo guhuza <0.5m

• Urusobe rw'insingaInsinga zoroshye 2.5–16mm² / Insinga ikomeye 2.5–25mm²

• Guhuza Uburinzi: Igomba gukorana n'udukingirizo duto cyangwa fuse

• Isano ry'Isi: Ubuso bw'insinga yo hasi ≥4mm²

Gushyiraho neza no gusiga hasi ni ingenzi cyane kugira ngo uburinzi burusheho gukora neza.
