Aload breakchinja chinhu chemagetsi pakati peahigh-voltage circuit breakeruye ahigh-voltage isolation switch . Muchinyorwa chino, ngatitarisei pamusimboti wekushanda wekuremerwa chinja uye mutsauko uripo pakati pemutoro wekutyora switch uye wedunhu breaker.
Kushanda musimboti weload break switch
Iyo yakakwirira-voltageload break switch inoshanda zvakafanana kune yedunhu breaker. Kazhinji, kuisirwa nyore arc yekudzima mudziyo, asi chimiro chayo chiri nyore. Mufananidzo wacho unoratidza iyo yakakwira-kumanikidza mutoro break switch yemhepo yakamanikidzwa. Basa rayo rekushanda nderokuti: kana bhureki ravhurwa, pasi pechiito chekuvhura chitubu, spindle inotenderedzwa wachi. Kune rumwe rutivi, piston inokwira kumusoro kuburikidza ne crank slider mechanism yekumanikidza gasi; Kune rimwe divi, kuburikidza neiyo nzira yekufambisa inoumbwa neseti mbiri dzechina-link mechanism, banga guru rinovhurwa kutanga, uye ipapo arc breaker inosundirwa kuvhura iyo arc breaker kusangana, uye mweya wakamanikidzwa mucylinder unopeperetswa kunze. kuburikidza nenozzle kuburitsa arc.
Kana uchivhara, iyo main cutter uye arc breaker inotenderera newachi panguva imwe chete kuburikidza ne spindle uye transmission system, uye iyo arc breaker yekubata inovharwa kutanga. Iyo spindle inoramba ichitenderera kuitira kuti iyo huru yekubatanidza inovhara gare gare. Munguva yekuvhara, chitubu chekuvhura panguva imwechete inochengetedza simba. Nekuti mutoro wekutyora switch haugone kutyora ipfupi redunhu ikozvino, inowanzo shandiswa neizvino inodzikamisa yakakwira voltage fuse. Ikozvino kudzikamisa basa reiyo yazvino yekumisikidza fuse haingopedzi basa rekupwanya redunhu, asi zvakare inoderedza zvakanyanya pesvedzero yesimba rinopisa uye remagetsi rinokonzerwa nepfupi wedunhu ikozvino.
Naizvozvo, load break switch ndiyo inoshandura mudziyo pakati pedunhu breaker uye yekuzviparadzanisa switch. Iyo ine yakareruka arc yekudzima mudziyo, iyo inogona kugura yakayerwa mutoro wazvino uye imwe yakawandisa yazvino, asi haigone kudzima iyo pfupi yedunhu ikozvino.
Musiyano uripo pakati pemutoro break switch uye circuit breakers
Kubva pamaonero echinyakare, twunhu twunoremerwa twunosiyana zvakanyanya nevanotyora dunhu. Load break switch inonyanya kushandiswa kutyora uye kuvhara mutoro ikozvino. Inogona kushandiswa ne-high-voltage fuses kutsiva high-priced circuit breakers uye kubvisa kukanganisa ikozvino, kureva, pfupi-circuit current. Zvinotemerwa kuti arc yekudzima basa remutoro break switch haina kusimba, iyo inoderedza mutengo wekugadzira. Izvo chaizvo nekuti iyo yechinyakare yekuremerwa switch switch haishandiswe kucheka mutsauko uripo pakati pechikanganiso chazvino fuse uye wedunhu breaker, hapana chikonzero chekubatanidza mudziyo wekudzivirira uye otomatiki mudziyo, saka yakawanda yekuremerwa chinja switch iri pamaoko. akavhiyiwa. Haikwanise kushandiswa nemagetsi. Muchigadziro chemugero wedunhu, inofungidzirwa kuti kwete chete iyo inotakura ikozvino inogona kuvhurwa uye kudzima.
Shanduko dzakagadzirirwa kubata zvazvino (kukanganisa ikozvino, kwakayerwa ikozvino) idzodzi dzedunhu, uye nhanho yekupwanya kuvharwa kwemagetsi edunhu yakadzikira, saka kugona kubata overvoltage hakuna kusimba. Iyo switch yakanyatso kugadzirirwa kubata nevoltage (iyo insulation level yekutyoka yakakwira zvakanyanya, iyo inogona kubata neiyo yakakwira fracture voltage inomira kukosha) ndiyo yekuzviparadzanisa switch, inowanzo zivikanwa sechishandiso brake. Load break switch is switch pakati pezviviri zvinogona kubata zvazvino (yakatemerwa ikozvino) uye voltage (iyo yekuvharisa nhanho yekupwanya yakakwira kupfuura yedunhu breaker, asi yakaderera pane yekuzviparadzanisa switch), asi kunyangwe iyo yekuremerwa yekutyora inogona kutyora uye kuvhara yakarongerwa ikozvino, kuvhara pfupi yedunhu ikozvino, asi inorambidzwa zvachose kuputsa pfupi yedunhu ikozvino.
Uyu ndiwo musimboti wekushanda weload break switch uye mutsauko uripo pakati peload break switch uye circuit breaker.
