BHC pakali pano chosinthira circuit breaker

Makhalidwe ofunika

Zokhudzana ndi mafakitale

BHC breaker imagawidwa m'mitengo ya 2 ndi mitengo 4.Itha kugwiritsidwa ntchito pa chophwanyira dera chomwe chimayikidwa pagawo lowongolera la zida zoyambira, ndipo chitha kugwiritsidwanso ntchito poyang'anira malo ogulitsira, malo oyambira ndi bolodi lamagetsi apanyumba.

Mankhwalawa ali ndi chitetezo chokwanira kwambiri.

Osakhudzidwa ndi kutentha kozungulira.

Multi-step chosinthika cha oveteredwa panopa

4, Mounting Condition

1) Kutentha kwa mpweya wozungulira
1) Poganizira kutentha kwambiri yozungulira kufulumizitsa ukalamba mbali pulasitiki, malire chapamwamba si oposa +40 ℃.

Poganizira kuti otsika kwambiri yozungulira kutentha kwambiri

amasintha kukwanira kwa membala wamapangidwe, malire apansi nthawi zambiri amakhala osatsika kuposa -5 ℃.
Poganizira za moyo wautumiki wa wophwanya dera, mtengo wapakati wa maola 24 siwopitilira +35 ℃.

Zindikirani:

① Mkhalidwe wogwirira ntchito wamtengo wotsika wotsika ndi -10 ℃ kapena -25 ℃.Wogwiritsa ntchito ayenera kulengeza ku kampaniyo poyitanitsa.

②Mkhalidwe wogwirira ntchito wamtengo wapamwamba wopitilira +40 ℃ kapena mtengo wotsika wotsika kuposa -25 ℃, wogwiritsa ntchito ayenera kukambirana ndi kampaniyo.

2) Malo oyika

Kutalika sikudutsa 2000m;
Zofunikira zozungulira chitetezo;
Malo oyikapo amawerengera chigawo chachifupi chamakono Ik sichiposa 3000A;
Wophwanyira dera adzakhazikitsidwa malinga ndi zofunikira pakugwiritsa ntchito bukhuli, kupendekera kosunthika kwa wophwanyira dera sikuyenera kupitilira 5 °, Kugwedezeka kwachilengedwe sikupitilira 5g.

3) Zinthu Zamlengalenga

Chinyezi chachibale cha mlengalenga sichidutsa 50% pa kutentha kwa mpweya wozungulira +40 ° C. Ikhoza kukhala ndi chinyezi chapamwamba pamtunda wochepa.Kutentha kwapakati pamwezi kwa mwezi wamvula kwambiri ndi 90%, ndipo kutentha kwapakati pa mweziwo ndi +25 ° C ndikuganiziranso kusungunuka pamwamba pa mankhwala chifukwa cha kusintha kwa kutentha.

4) Kuipitsa mlingo

Mulingo wa kuipitsidwa ndi level 3.

5) Kukhazikitsa Gulu

Dongosolo lachitetezo chachitetezo chozungulira limayikidwa mugulu la III.

1) Gawo la mtanda wa waya limakonzedwa molingana ndi kutentha kwanthawi zonse Ith ya wowononga dera.
