Fuse yakakamurwa kuita hukuru hutanhatu zvichienderana nehukuru hwefuse chubhu.Saizi yega yega ine conesponding rated current range.Tarisa kune main tekinoroji paramita kune yakayerwa cun ent nhanho yefuse yemasaizi akasiyana.Iyo fuse inogona kuve yakashongedzerwa ine impactor zvinoenderana nezvinodiwa nemushandisi, uye impactor inowanzowanikwa yakananga pamusoro peiyo fuse yekubata.
Nomenclature yemafusi
Mamiriro ekushanda akajairika
◆Ambient air tembiricha
Iyo tembiricha yemhepo yakadzika haifaniri kudarika 40 ° C, avhareji kukosha yakayerwa mumaawa makumi maviri nemana haingapfuuri 35 C, uye avhareji kukosha kwakayerwa mugore rimwe ichave yakaderera pane iyi kukosha.
Iyo shoma ambient tembiricha yemhepo - 5 C.
◆Altitude
Kukwirira kwenzvimbo yekuisa hakufaniri kudarika 2000m.
◆Atmospheric mamiriro
Hunyoro hwayo haufanire kudarika 50% patembiricha yepamusoro ye40°C
Hunyoro hwepamusoro hunogona kuwanikwa pane tembiricha yakaderera, semuenzaniso, kusvika 90% pa20C.
Pasi pemamiriro ezvinhu aya, kupera kwepakati kunogona kuitika nemukana nekuda kwekushanduka kwekushisa.Pasina kubvunzana nemugadziri, iyo fuse haigone kuisirwa munzvimbo ine mhute yemunyu kana isina kujairika dhipoziti yeindasitiri.
◆Voltage
Iyo yakanyanya system voltage haifaniri kudarika 1 10% yeiyo yakatemerwa fuse voltage.
Kune fuse ine rated voltage ye690V AC uye 250V 1440V DC, iyo yakanyanya system voltage haifanire kudarika 105% yeyakayerwa voltage yefuse.
Normal kuiswa mamiriro
◆Kuisa chikamu
Chikamu chekuisa chefuse kirasi I.
◆ Mwero wekusvibiswa
Iyo anti kusvibiswa dhigirii yefuse haifanirwe kuve yakaderera pane level3.
◆Instalation mode
Iyo fuse inogona kuisirwa yakatwasuka, yakachinjika kana yakatsveyama munzvimbo yebasa pasina kuzununguka kwakakosha uye kukanganisa vibration.
Kutyora siyana uye kushandiswa chikamu
Runongedzo rwefiyuzi ibatanidzi yefuse ine chinangwa chakazara uye yakakwana yekupwanya siyana, kureva "gG" link yefuse.
Mamiriro ezvinhu uye nheyo yekushanda
Iyo fuse ine fuse base uye fuse link.Iyo fuse base inoumbwa ne base contact, base plate, nezvimwewo.
Kana iyo fuse yakaiswa mudunhu, kana ikozvino inopfuura nepakati pefuse inodarika imwe kukosha kwenguva yakakwana, iyo inonyunguduka mumutumbi wefuse inosanganiswa, uye arc inogadzirwa kana fuse ichibatanidzwa nejecha requartz mu fuse. chubhu ichadzimwa, kuitira kuti uwane chinangwa chekuputsa dunhu.
Kana iyo yakanyungudutswa ichivhuvhuta, chiratidzo chiri pafuse chinongedzo chinobuda, zvichiratidza kuti iyo fuse link inoputika.
Kune iyo fuse yakashongedzerwa ine impactor, kana iyo melt yasanganiswa, iyo impactor inobuda yega.Mushandisi anongoda chete kuisa micro-switch kana yakakodzera chiratidzo chekutumira chishandiso (chakasarudzwa uye chakatengwa nemushandisi) pamberi peiyo impactor, uye ipapo chiratidzo chinodiwa chinogona kuwanikwa mushure mekunge fuse yasanganiswa.
