Imigaqo esisiseko yekhabhinethi yembuyekezo ye-high-voltage capacitor: Kwiinkqubo zamandla okwenene, uninzi lwemithwalo ziimotor asynchronous.Isekethe yabo elinganayo inokuthathwa njengoluhlu lweesekethe zokuchasana kunye ne-inductance, kunye nokwahlukana kwesigaba esikhulu phakathi kwe-voltage kunye ne-current and low power factor.Xa i-capacitors ixhunyiwe ngokuhambelanayo, i-capacitor yangoku iya kucima inxalenye ye-current induced current, ngaloo ndlela inciphisa i-current induced, ukunciphisa i-current total, ukunciphisa umehluko wesigaba phakathi kwe-voltage kunye ne-current, kunye nokuphucula umbane wamandla.1. Inkqubo yokutshintsha ikhabhinethi yeCapacitor.Xa ikhabhinethi ye-capacitor ivaliwe, inxalenye yokuqala kufuneka ivalwe kuqala, kwaye inxalenye yesibini;xa uvala, okuchaseneyo kuyinyaniso.Ukutshintsha ulandelelwano lweekhabhinethi ze-capacitor zokusebenza.Ukuvala ngesandla: vala iswitshi yokwahlula → tshintshela iswitshi yolawulo lwesibini kwindawo yezandla kwaye uvale iqela ngalinye le-capacitors nganye nganye.Ukuvulwa kweManuwali: tshintsha iswitshi yolawulo lwesibini kwimo yezandla, vula iqela ngalinye le-capacitors nganye nganye → yaphula iswitshi yokuzahlula.Ukuvala ngokuzenzekelayo: vala iswitshi yodwa → tshintsha isitshixo solawulo lwesibini kwindawo ezenzekelayo, kwaye umxhasi wamandla uya kuvala ngokuzenzekelayo i-capacitor.Qaphela: Ukuba ufuna ukuphuma kwikhabhinethi ye-capacitor ngexesha lokusebenza, unokucofa iqhosha lokusetha kwakhona kwi-comensator yamandla okanye ujike i-second control switch kwi-zero ukuphuma kwi-capacitor.Musa ukusebenzisa iswitshi yodwa ukuphuma kwi-capacitor esebenzayo ngokuthe ngqo!Xa ukutshintshwa kwencwadana okanye ngokuzenzekelayo, ingqalelo kufuneka ihlawulwe ekutshintsheni ngokuphindaphindiweyo ibhanki ye-capacitor ngexesha elifutshane.Ixesha lokulibaziseka lokutshintsha akufanele libe ngaphantsi kwemizuzwana ye-30, ngokukhethekileyo ikhulu kunemizuzwana ye-60, ukuvumela ixesha elaneleyo lokukhutshwa kwi-capacitors.2. Misa kwaye unikeze amandla kwikhabhinethi ye-capacitor.Ngaphambi kokubonelela amandla kwikhabhinethi ye-capacitor, i-breaker circuit kufuneka ibe kwindawo evulekileyo, ukutshintshwa komyalelo kwipaneli yokusebenza kufuneka ibe kwindawo ethi "Stop", kwaye umlawuli wembuyekezo yombane kufuneka ube kwindawo ethi "OFF".Kuphela emva kokuba inkqubo ihlawuliswe ngokupheleleyo kwaye isebenze ngokuqhelekileyo inokunikwa amandla kwikhabhinethi ye-capacitor.Ukusebenza ngesandla kwekhabhinethi ye-capacitor: vala i-circuit breaker yekhabhinethi ye-capacitor, tshintshela ukutshintshwa komyalelo kwipaneli yokusebenza kwizikhundla ze-1 kunye ne-2, kwaye udibanise ngesandla imbuyekezo ye-capacitors 1 kunye ne-2;vula ukutshintshwa komyalelo kwindawo "yokuvavanya", kwaye ikhabhinethi ye-capacitor iya kuvavanywa iibhanki zeCapacitor.Ukusebenza okuzenzekelayo kwekhabhathi ye-capacitor: vala isaphuli sesiphaluka sekhabhathi ye-capacitor, tshintsha isitshixo somyalelo kwiphaneli yokusebenza kwindawo "ezenzekelayo", vala isilawuli solawulo lwembuyekezo yamandla (ON), kwaye utshintshe isitshixo somyalelo kwi "run". ” isikhundla.” isikhundla.Ikhabhinethi ye-capacitor ihlawula ngokuzenzekelayo amandla asebenzayo enkqubo ngokwemimiselo yenkqubo.Imbuyekezo yezandla ingasetyenziselwa kuphela xa imbuyekezo ngokuzenzekelayo yekhabhinethi ye-capacitor ingaphumeleli.Xa ukutshintshwa komyalelo kwipaneli yokusebenza yekhabhinethi ye-capacitor itshintshelwe kwindawo "yokumisa", ikhabhinethi ye-capacitor iyayeka ukusebenza.Ntathu.Ulwazi olongezelelweyo malunga neekhabhinethi ze-capacitor.Kutheni iKhabhinethi yembuyekezo ye-capacitor ingenayo i-air switch kodwa ixhomekeke kwi-fuse yokukhusela isiphaluka esifutshane?Iifuse zisetyenziselwa ikakhulu ukukhusela isiphaluka esifutshane, kwaye iifuse ezikhawulezayo kufuneka zikhethwe.Iziqhekezi zesekethe ezincinci (MCBs) zineejiko zophawu olwahlukileyo kune-fuses.Umthamo wokuphulwa kwe-MCB uphantsi kakhulu (<= 6000A).Xa kwenzeka ingozi, ixesha lokuphendula le-breaker circuit encinci alikho ngokukhawuleza njengelo fuse.Xa udibana ne-harmonics ephezulu, i-miniature breaker circuit breaker ayikwazi ukuphazamisa umbane wangoku, onokubangela ukuba utshintsho luqhume kwaye lonakaliswe.Ngenxa yokuba i-fault current ikhulu kakhulu, abafowunelwa be-miniature circuit breaker banokutshiswa, okwenza kube nzima ukuphula, ukwandisa ububanzi besiphoso.Kwiimeko ezinzima, kunokubangela isiphaluka esifutshane okanye ukuphuma kombane kwisityalo sonke.Ngoko ke, i-MCB ayinakusetyenziswa njengokutshintshwa kweefuse kwiikhabhinethi ze-capacitor.Indlela i-fuse esebenza ngayo: Ifuse idityaniswe ngokulandelelana kunye nesekethe ekhuselweyo.Kwiimeko eziqhelekileyo, i-fuse ivumela umlinganiselo othile wangoku ukuba udlule.Xa isiphaluka sifutshane okanye sigxininiswe kakhulu, i-fault current current ihamba nge-fuse.Xa ubushushu obuveliswa ngumbane bufikelela kwindawo yokunyibilika kwefuse, i-fuse iyancibilika kwaye inqumle isiphaluka, ngaloo ndlela ifezekisa injongo yokukhusela.Uninzi lokukhusela i-capacitor lusebenzisa i-fuses ukukhusela i-capacitors, kwaye i-breakers circuit ayifane isetyenziswe, phantse akukho nanye.Ukukhethwa kwee-fuses ukukhusela i-capacitors: I-current rated current ye-fuse ayifanele ibe ngaphantsi kwe-1.43 yamaxesha angoku ye-capacitor, kwaye ayifanele ibe ngaphezu kwe-1.55 yangoku ye-capacitor.Jonga ukuze ubone ukuba i-breaker circuit is undersized.I-capacitor iya kuvelisa i-surge current ethile xa ixhunyiwe okanye inqanyuliwe, ngoko ke i-breaker circuit kunye ne-fuse kufuneka ikhethwe ukuba ibe nkulu kancinane.
