Overview
RW12 akatevedzana anodonhedza-mafuse midziyo yekunze yakakwira-voltage yekudzivirira mumagetsi ekufambisa uye masisitimu ekuparadzira.Iwo akaiswa padivi repamusoro-voltage yekugovera shandurudzo kana mitsara yebazi yekugovera mitsetse yepfupi-yedunhu uye inorema kudzivirira yetransformer uye mitsetse, pamwe neiyo shunting uye kubatanidza mitoro mitoro.Iyo yakakwirira-voltage ceramic drop-out fuse ine ceramic insulating bracket uye fuse chubhu.Iwo ma static contacts anoiswa kumigumo ese e insulating bracket, uye anofambisa macontact anoiswa kumigumo yese yefuse chubhu.Iyo fuse chubhu ine yemukati arc suppression chubhu uye fuse chubhu.Iyo yekunze layer inoumbwa ne phenolic bepa chubhu kana epoxy girazi jira chubhu.
Features
Melting tube chimiro:
Iyo fuse inogadzirwa neflberglsaa, inova mwando uye isingadzivirirwe nekuora.
Fuse base:
Chigadziko chechigadzirwa chakamisikidzwa nema mechanical zvimiro uye insulators.Iyo simbi tsvimbo meshini inoiswa neyakakosha adhesive zvinhu uye insulator, iyo inogona kumira pfupi yedunhu ikozvino kuvhura simba.
Fuse-inoratidza unyoro haina mabhubhu, haina deformation, haina dunhu rakavhurika, hukuru hukuru, anti-ultraviolet, hupenyu hurefu, hukuru hwemagetsi zvivakwa, dielectric simba uye yakanakisa mechanical rigidity uye kugona kuzvipira.
Iyo yese michina haina kwayakarerekera, nyore kuisa, yakachengeteka uye yakavimbika.
Kuiswa kwemafusi ekudonha
(1) Kunyunguduka kunofanira kusimbiswa panguva yekuisa (kuitira kuti iyo inonyunguduka igone kumira nesimba rinosvika 24.5N), zvikasadaro zviri nyore kuita kuti vanobatika vawedzere.
(2) Fuse yakaiswa pamuchinjikwa ruoko (frame) inofanira kuva yakasimba uye yakavimbika, uye hapafaniri kuva nekudedera kana kuzununguka.
(3) Iyo chubhu inonyunguduka inofanira kuva nekona yekudzika yakadzika ye25 ° ± 2 °, kuitira kuti chubhu inonyunguduka inokurumidza kuwira pasi nehuremu hwayo painoputika kunze kwekunyungudika.
(4) Fuse inofanira kuiswa pamuchinjikwa ruoko (frame) ine vertical distance isingasviki 4m kubva pasi.Kana iyo yakaiswa pamusoro peshanduro yekugovera, inofanirwa kuchengetedza yakatwasuka kureba inopfuura 0.5m kubva kune yekunze contour muganhu wekugovera transformer.Kudonha kwechubhu yakanyungudutswa kwakakonzera dzimwe tsaona.
(5) Kureba kwefuse kunofanira kugadziriswa zvakakodzera.Zvinotarisirwa kuti duckbill inogona kuchengetedza zvinopfuura zvikamu zviviri kubva muzvitatu zvehurefu hwekuonana mushure mekuvhara, kuitira kuti udzivise kuwira pasi misoperation panguva yekushanda, uye fuse tube haifaniri kurova duckbill., kudzivirira kuti chubhu inonyunguduka irege kudonha nenguva mushure mekunge kunyungudika kwaputika.
(6) Kunyungudika kunoshandiswa kunofanirwa kunge kuri chigadzirwa chemugadziri wenguva dzose uye kuve nehumwe simba remagetsi.Zvinowanzodiwa kuti kunyunguduka kugone kumira nechisimba chiri pamusoro pe147N.
(7) 10kV drop-out fuse anoiswa panze, uye chinhambwe chinodiwa kuti chive chinopfuura 70cm.
