Overview
High voltage fuse ndicho chinhu chisina kusimba chakaiswa mune yemagetsi grid.Kana iyo-over-current ichiyerera, iyo element pachayo ichapisa uye fuse, uye dunhu richaputswa nebasa rearc yekudzima svikiro kuchengetedza tambo dzemagetsi nemidziyo yemagetsi.Mafusi anoshandiswa zvakanyanya mudiki magidhi emagetsi ane voltage ari pasi pe35 kV.
Iyo fuse ine fuse chubhu, yekubata conductive system, post insulator uye base plate (kana mounting plate).Inogona kukamurwa kuita yazvino inomisa fuse uye yekudonha fuse.
Chimiro
Iyo fuse yeiyi nhevedzano ine maviri post insulators, yekubata base, fuse chubhu uye base ndiro.Iyo positi insulator yakaiswa pahwaro ndiro, chigaro chekusangana chinogadzikwa pane post insulator, uye fuse chubhu inoiswa pachigaro chekusangana uye yakagadziriswa, asi zvivharo zvemhangura kumativi ese ari maviri akakuvadzwa pane porcelain chubhu, uye fuse. mune fuse barrel yakayerwa zvichienderana nehukuru hwazvino.Imwe kana kupfuura fuse yakakuvadzwa paribbed core (yakatemerwa ikozvino isingasviki 7.5A) kana yakananga kuiswa muchubhu (yakayerwa ikozvino yakakura kupfuura 7.5A), uye yobva yazadzwa nejecha requartz.Zvivharo zvemhangura zvinoshandiswa kumativi ose maviri.Kana iyo yakawandisa ikozvino kana pfupi yedunhu ikozvino inopfuura, iyo fuse inoputika nekukurumidza, uye iyo arc ichagadzirwa panguva imwe chete, uye jecha requartz rinodzima arc nekukurumidza.Kana iyo fuse ichivhuvhuta, tambo yechitubu inovhuvhutawo uye inobuda kunze kwechitubu, zvichiratidza kuti fuse inoputika.Kupedzisa basa.
Mirayiridzo yekushandisa
RN1 mhando yemukati yakazadzwa quartz jecha fuse, yakakodzera:
(1) Kukwirira hakuna kukwira kupfuura 1000 metres.
(2) Tembiricha yepakati yakatenderedza haina kukwira kupfuura +40 ℃, kwete yakaderera pane -40 ℃.
Type RN1 fuse haigone kushanda munzvimbo dzinotevera:
(1) Nzvimbo dzemukati dzine hunyoro hunopfuura 95%.
(2) Pane nzvimbo dzine njodzi yekupisa zvinhu uye kuputika.
(3) Nzvimbo dzine kuzunguzika kwakanyanya, swing kana kukanganisa.
(4) Nzvimbo dzine hurefu hunodarika 2,000 metres.
(5) Nzvimbo dzakasvibiswa nemhepo nenzvimbo dzakanyorova.
(6) Nzvimbo dzakakosha (sedzinoshandiswa mumidziyo yeX-ray).
