Umahluko phakathi kwebhokisi yesebe lentambo kunye neyunithi ephambili yeringi

Umsebenzi ophambili webhokisi yesebe lentambo kukwahlulahlula okanye ukutshintsha iintambo. Ukuqhawuka kweentambo. Ukuthwala iintambo ezininzi ezincinci kwindawo yonke kwindlela enomgama omde kudla ngokukhokelela ekugqithiseni nasekuchitheni ukusetyenziswa kweentambo, ngoko ke xa zingaphandle kwemida yomthwalo wamandla, ipali ephambili kunye neentambo ezinkulu zihlala zisetyenziswa ngaphandle kwemida. Ikhabhathi yomthi yokusasaza okanye yokudlulisa iintambo, eyahlulwe yaba yi-X in kunye ne-X out, yokusasaza umthwalo okanye yokudlulisa iintambo ezinde.
Iyunithi ephambili yeringi: ibhokisi yokusasaza intambo eneswitshi ingasebenza kude. Isitishi sokutshintsha: isikhululo sokusasaza esincinci nesiphakathi esingenamntu esinomzila webhasi omnye okanye uqhagamshelo lwebhasi enye ngokwecandelo

Iibhokisi zesebe leentambo zihlala zisetyenziswa ngaphandle. Ngophuhliso lwetekhnoloji, iibhokisi zesebe leentambo ezineeswitshi nazo ziphuculwa rhoqo, kwaye iintambo kwizixeko ezinkulu zihlala zisebenzisa indlela yokubonelela ngombane yesekethe ezimbini, ngoko ke abantu abaninzi bazibiza ngoko nangoko ngokuba yibhokisi yesebe eneswitshi. Yiyunithi ephambili yeringi yangaphandle, kodwa uninzi lweyunithi ephambili yeringi kweli nqanaba alukwazi ukugcina ukwenziwa kwezinto ngokuzenzekelayo.

1. Izinto eziyinxalenye yeyunithi ephambili yeringi:
Iyunithi ephambili yeringi eyaziwa ngokuba yi-enterprise yenkqubo yombane wenethiwekhi yeringi, liqela loomatshini kunye nezixhobo ze-high-voltage circuit breaker ezifakwe kwi-thick steel plate metal material cabinet body okanye izixhobo zombane ezenziwe kwi-assembly spacing ring network power supply module, ezinye zazo zisebenzisa ii-load switches kunye nee-high voltage fuses. Iyunithi nganye ephambili yeringi inikwe indlela yokunxibelelana eguquguqukayo yeebhokisi ezisezantsi ezi-3 ukuya kwezi-5, ukuze kuqwalaselwe iimfuno zenkqubo yombane yee-nodes ezahlukeneyo zenethiwekhi yokusasazwa kobunjineli bamandla. Ngenxa yokuba izixhobo eziphambili zokutshintsha umbane kunye ne-hard busbar zifakwe kwi-casing efanayo yentsimbi evaliweyo, zihlala zisetyenziswa njengeeleya zokuvala kunye nezinto zokucima i-arc. I-snap-yellow tissue inokugcina iswitshi isebenza ngokukhawuleza. Imodyuli yenethiwekhi yeringi ezimeleyo yenziwe ngeemodyuli zolawulo ezahlukeneyo kunye neemodyuli zebhasi ezifana neenkampani ezineentambo ezintlanu zesigaba sesithathu, iiyunithi zobuninzi, amashishini eTV, njl.njl., kwaye zinokwenza iiskimu ezahlukeneyo ngokuthanda ngokweemfuno zokwenyani.

2. udidi lweyunithi ephambili yeringi:

Iyunithi ephambili yeringi inokwahlulwa ibe ziintlobo ezine:

a. Iyunithi ephambili yeringi yohlobo lwepompo yomoya: Iyunithi ephambili yeringi yohlobo lwepompo yomoya sisizukulwana esitsha sokhuselo oluluhlaza lokusingqongileyo oluyimveliso yeringi yomoya yomoya. Le mveliso isebenzisa i-vacuum circuit breaker + isixhobo sokukhusela i-microcomputer, kwaye zonke iisekethe eziqhubayo zisebenzisa i-epoxy resin glue okanye i-silica gel. I-encapsulation iqinisekisa ukhuseleko oluphezulu ekusebenzeni nasekusebenzeni kwangempela, kwaye i-voltage elinganisiweyo yesicelo inokufikelela kwi-24KV.
b. Iyunithi ephambili yeringi ye-SF6: Iyunithi ephambili yeringi ye-SF6 luhlobo lwezixhobo zasekhaya ezine-voltage ephezulu ezinomaleko wokugquma igesi okanye umaleko wokugquma umphunga oneswitshi yomthwalo njengecandelo eliphambili, elinokwakhiwa ngokulula ngokufikelela kwiisekethe ezininzi, ukuguqulwa, uqhagamshelo kunye nokugcinwa kwenkqubo yombane. Oomatshini bokwenza izinto. Izinto zayo eziphambili zesekethe zenziwe yiswitshi yomthwalo ye-SF6 okanye iswitshi eyongezelelweyo yokuzihlukanisa kunye nezinye izixhobo ezincedisayo kunye nezixhobo zasekhaya.
c. Iyunithi ephambili yeringi evelisa igesi: Iyunithi ephambili yeringi evelisa igesi yenziwe ngezinto eziluhlaza eziqinileyo ezivelisa igesi (ezifana neepleyiti ze-plexiglass) ukwenza izinto zokucima i-arc. Izinto eziluhlaza ezivelisa igesi ziguqulwa zibe yigesi, epholisa amanzi ombane ize iwavuthele. Okukhona inani lamandla ombane aqhekekileyo kunye nalawo adibeneyo lilikhulu, kokukhona ukuhlukaniswa kombane kuqina, kokukhona igesi eguquliweyo iba nkulu, kwaye kokukhona isiphumo sokwenyani sokucima i-arc siba phezulu.
d. Iyunithi ephambili yeringi yomoya ecinezelweyo: Iyunithi ephambili yeringi yomoya ecinezelweyo ibizwa ngegama lokukhethwa kweswitshi yomthwalo womoya ocinezelweyo. Iswitshi yomoya ecinezelweyo isebenzisa ucinezelo lomoya ukuvuthela i-arc. Xa itsalwa, intonga yepiston yomoya ecinezelweyo ihamba ngokukhawuleza, kwaye igesi yoxinzelelo oluphezulu kwisilinda ivuthelwa ngaphandle ukuya kwindawo yokwahlulwa kombane nge-nozzle xa i-arc extinguishing circuit breaker yahlulwe ukuze kubangele ukwahlulwa kombane. Yenza i-electrical solitary ibe nde kwaye uyivuthele xa umbane uphantsi. Ngokubanzi, umbane weswitshi yomthwalo womoya ocinezelweyo umalunga ne-1 kA, ukuze kufezekiswe amandla okuqhekeza kunye nombane omfutshane we-50 kA. Umbane ozinzileyo wobushushu ngokubanzi yi-20 kA, 3s.

3. Zithini iimpawu zesakhiwo sekhabhathi yenethiwekhi yeringi?
a. Ikhabhathi yenethiwekhi yeringi yenziwe ngamacandelo amane: igumbi lokutshintsha, igumbi lefuse elinombane ophezulu, igumbi lokulungiselela ukusebenza kunye negumbi lekhebula (ipringi yepleyiti).
b. Igumbi lokutshintsha lenziwe yisekethe nganye esebenzayo (kubandakanya iswitshi yesixhobo sokumisa umhlaba kunye neswitshi yomthwalo) evalwe kwikhava yezinto zesinyithi kunye nebhasi phakathi kweesekethe. Isiciko sidityaniswe nge-welding yombane yepleyiti eqengqelekayo ebandayo eyi-3mm (okanye ipleyiti yentsimbi etyebileyo engenamthungo). Isekethe nganye yesenzo ineswitshi yomthwalo kunye neswitshi yokumisa umhlaba. Iswitshi yomthwalo yenziwe yisoftware yenkqubo yokumisa isekethe yokuhamba yentshukumo yokuqina komzimba ethe nkqo kunye noqhagamshelwano olungaguqukiyo olufumaneka kwisiphelo sewebhu esisezantsi. Xa iswitshi ivaliwe kwakhona, i-moving circuit breaker iya ezantsi kwaye iswitshi yomthwalo iqhagamshelwe. Iswitshi yesixhobo sokumisa umhlaba yenziwe ngemela yokunxibelelana eshukumayo kunye nemela yokunxibelelana engaguqukiyo. Ngexesha lonke lenkqubo yokuzilolonga okumthubi okutsibayo, iswitshi yesixhobo sokumisa umhlaba iqhagamshelwe ngokukhawuleza. Kukho imingxunya yenkqubo yokulungisa izikwere ezi-4 phezulu nangasemva kwegumbi lokutshintsha, kwaye icala elingasemva leyunithi ephambili yeringi lixhotyiswe ngefestile yokujonga, kwaye iindawo "zokwahlula" kunye "nokuvala" kweswitshi yesixhobo sokumisa umhlaba zinokubonakala. Icala elingasemva leyunithi ephambili yeringi lixhotyiswe ngezixhobo ezikhusela ukuqhuma.
c. Iswitshi yomthwalo isebenzisa isakhiwo sokuvuthela umoya ocinezelweyo, esinamandla okucima i-arc kwaye asiyonakalisi imibala emibini kunye nomaleko wokukhusela emhlabeni. Zombini ezi contacts eziguquguqukayo nezizinzileyo ziqulathe iziphuli-sekethe ze-arc, nto leyo ephucula ngakumbi i-break frequency.
d. I-fuse ene-voltage ephezulu kunye negumbi lokutshintsha umthwalo zenza isekethe yokulungisa i-transformer. I-fuse ene-voltage ephezulu ifakwe kwisigqubuthelo sokukhusela i-epoxy resin-cast. Emva kokuba i-fuse ene-voltage ephezulu ivuthelwe, i-striker iyaphuma kwaye i-load switch ivaliwe.
e. Igumbi lolungiselelo lokusebenza likwicala elichaseneyo leyunithi ephambili yeringi. Kwisekethe nganye yesenzo, iswitshi yomthwalo ixhotyiswe ngentwasahlobo yokusebenza kweteknoloji yokugcina amandla yabasebenzi (okanye yombane), kwaye iswitshi yesixhobo sokumisa umhlaba ixhotyiswe ngentwasahlobo yokugcina amandla yabasebenzi. Iyunithi yokusebenza etyheli, iphaneli yokulawula ineemingxuma zokusebenza ngokwenene kweswitshi yomthwalo kunye neqhosha elijikelezayo lokutsala ngesandla kunye neswitshi yesixhobo sokumisa umhlaba, kunye nemingxuma yokusebenza yokwenene yeswitshi yomthwalo, ukuvula kunye nokuvala izibane zokubonisa isikhundla kunye nohlobo lombane Vula kwaye uvale amaqhosha kwakhona, kwaye usete umgca wokulinganisa wesimo sokulinganisa, isikrini sokubonisa imeko yeswitshi kunye nenxalenye yokutshixa, ukusebenza ngokwenene kweswitshi yomthwalo kunye neswitshi yesixhobo sokumisa umhlaba ixhotyiswe ngezixhobo ezidibeneyo ukuze kuthintelwe iimpazamo zokusebenza
