Iyunithi ephambili yeRing

IYunithi eyiRing Main liqela lezixhobo zombane zokuhambisa nokusasaza (iswitchgear ene-voltage ephezulu) efakwe kwikhabhathi yesinyithi okanye engeyiyo yesinyithi okanye eyenziwe yaba yiyunithi yokubonelela ngombane wenethiwekhi yeringi yexeshana. Inxalenye yayo engundoqo isebenzisa iiswitshi zomthwalo kwaye i-fuse ineenzuzo zesakhiwo esilula, ubungakanani obuncinci, ixabiso eliphantsi, inokuphucula iiparameter zombane kunye nokusebenza, kunye nokhuseleko lombane. Isetyenziswa kakhulu kwizikhululo zokuhambisa kunye nezikhululo zohlobo lwebhokisi zamaziko omthwalo kwiindawo zokuhlala zasezidolophini, izakhiwo eziphakamileyo, izakhiwo zikawonke-wonke ezinkulu, iifektri kunye namashishini.

Iintlobo ezininzi zeekhabhathi ze-net

Uhlobo lwe-HXGN-10

(Iyunithi ephambili ye-H-Ring; uhlobo lwebhokisi le-X; uhlobo oluzinzileyo lwe-G; N-ngaphakathi) Ulwakhiwo lwekhabhinethi luhlanganiswe ngokugoba nokuwelda iipleyiti zentsimbi, kwaye inqanaba lokhuseleko yi-IP2X. Inxalenye ephezulu yekhabhinethi ligumbi le-busbar, kwaye igumbi lezixhobo likwindawo engaphambili kwigumbi le-busbar, lahlulwe ziipleyiti zentsimbi. Umbindi wekhabhinethi ligumbi lokutshintsha umthwalo, kwaye isahlulo sokukhusela silungiselelwe phakathi kweswitshi yomthwalo kunye nezinye izinto. Kwikhabhinethi yokungena nokuphuma kwentambo, umzantsi wekhabhinethi uxhotyiswe ngepleyiti yokugquma esuswayo; kwikhabhinethi yokungena nokuphuma ephezulu, umphezulu wekhabhinethi unokuxhotyiswa ngemibhobho yebhasi okanye iirakhi zokukhusela.

Uhlobo lwe-HXGN-10

Iyunithi ephambili yeringi yomoya yochungechunge lwe-HXGN-10 inezicwangciso ezili-15, apho isicwangciso 01 yikhabhinethi yefuse yokutshintsha umthwalo; isicwangciso 02 yikhabhinethi yokutshintsha umthwalo, zombini zixhotyiswe ngezitshixo zokumisa umhlaba; isicwangciso 09 yikhabhinethi yokulinganisa.

Iqokobhe lolu luhlu lwekhabhinethi yenethiwekhi yeringi lisebenzisa indibano yokugoba ipleyiti yentsimbi kunye nokubopha izikrufu ukwenza isakhiwo sesinyithi esivalekileyo ngokupheleleyo. Umzimba wekhabhinethi wenziwe ngee-4 ezimileyo, ikhava ephezulu, ezantsi ezantsi, iphaneli engaphambili, iphaneli engasemva, iphaneli esecaleni, njl. Umphambili wekhabhinethi yokutshintsha umthwalo uneminyango emibini ephezulu nesezantsi eqiniswe ngezikrufu; umphambili wekhabhinethi yefuse yokutshintsha umthwalo uneephaneli zeminyango emi-3. Kukho ifestile yokujonga emnyango ukuze kubonwe indawo yokutshintsha umthwalo kunye neswitshi yokumisa umhlaba; uqhagamshelo lwebha yebhasi phakathi kwekhabhinethi kunye nekhabhinethi lukwimo yeplagi yoqhagamshelwano lweplamu, kwaye ibha yebhasi ixhotyiswe ngesheya yokukhusela. Ibhokisi yezixhobo ingongezwa phezulu kwekhabhinethi ngokweemfuno zomsebenzisi.

Iswitshi yokulayisha efakwe kwikhabhathi yenethiwekhi yeringi ivelisa igesi, ayinaoyile kwaye ayinatyhefu; indlela yokusebenza ngesandla kunye neyombane yindlela yokugcina amandla entwasahlobo ye-torsion, enesakhiwo esilula kunye namandla aphantsi okusebenza.

Kukho izixhobo zokudibanisa ngoomatshini phakathi kweswitshi yomthwalo, iswitshi yokumisa umhlaba kunye nephaneli engaphambili. Ubudlelwane bokusebenza phakathi kwazo bulandelayo:

1) Emva kokuba iswitshi yokumisa umhlaba ivaliwe, iswitshi yokulayisha ayinakusebenza, kwaye iphaneli engaphambili inokuvulwa;

2) Emva kokuba iswitshi yokumisa umhlaba ivuliwe, iswitshi yokulayisha ingasetyenziswa, kodwa iphaneli engaphambili ayinakuvulwa;

3) Emva kokuba iswitshi yokulayisha ivuliwe, iswitshi yokumisa isiseko ingasetyenziswa kwaye iphaneli engaphambili ivulwe;

4) Emva kokuba iswitshi yokulayisha ivaliwe, iswitshi yokumisa umhlaba ayinakusebenza kwaye iphaneli engaphambili ayinakuvulwa.

Uhlobo lwe-GE
Le yimodeli engeniswe kwamanye amazwe, esebenzisa iswitshi yomthwalo ye-SF6. Indlela yokusebenza luhlobo lokugcina amandla entwasahlobo, enesixhobo sokuvala ngokukhawuleza kunye nokuvula ngokukhawuleza. Indlela yokuvula igcinwa ngokuzenzekelayo yintwasahlobo ngexesha lokuvala, kwaye ukukhubeka kulawulwa (kuxutyushwa) yi-opening coil okanye i-HRC fuse.

I-SF6 sisitshixo somthwalo, ibhokisi yegesi idityaniswe nge-laser yentsimbi engagqwaliyo, idityaniswe ngomoya ngokupheleleyo, akukho kuvuza kunye nee-gaskets zokuvala; phakathi kwazo, i-8DJ20 sisakhiwo sebhokisi yegesi eqhelekileyo esingenakwandiswa; i-8DH10 luhlobo olunokwandiswa; isebenzisa uyilo oluyimodyuli ukuhlangabezana neemfuno ezahlukeneyo. Iimfuno zabasebenzisi benethiwekhi yesiphelo kunye neringi. Inezibonelelo zesakhiwo esincinci, indawo encinci, kwaye ayinakugcinwa.

Isixhobo esikhuselayo

Ngokusekelwe kwiminyaka emininzi yamava okusetyenziswa kwabasebenzi basekhaya nabangaphandle kwisixhobo sokukhusela i-microcomputer seyunithi ephambili yeringi, kunye neempawu zokwenyani zenkqubo ye-automation edibeneyo yasekhaya, yimveliso ye-automation yamandla yobuchwepheshe obuphezulu edibanisa ukhuseleko, ukubeka iliso, ulawulo, unxibelelwano kunye neminye imisebenzi. Iyunithi yombane efanelekileyo kwi-switchgear ekrelekrele. Imveliso inethala leencwadi lokhuseleko elakhelwe ngaphakathi eliqulunqwe ziinkqubo zokhuseleko ezingaphezu kwama-20, elinomsebenzi opheleleyo nonamandla wokuqokelela i-voltage, ubungakanani be-analog yangoku kunye nobungakanani be-switch yezixhobo eziphambili (umlinganiselo wangoku ufezekiswa yi-CT yokhuseleko)

Ukhuseleko lwekhompyutha encinci
Ekubeni iyunithi ephambili yeringi iphantsi kombane ophezulu, kufuneka isixhobo sokukhusela ukukhusela iyunithi ephambili yeringi.

Isicelo:

Iyunithi ephambili yeringi ayizange ivele ixesha elide, kodwa ibisetyenziswa kakhulu. Oku kungenxa yezakhiwo ezisandula ukuphuhliswa zamashishini namaziko emizi-mveliso. Ngokwembono yobonelelo lwamandla nokusasazwa, phakathi kwazo, umthamo omncinci ngowona uphezulu. I-transformer yokusasazwa ngokubanzi ayidluli kwi-1250KVA, umbane ozinzileyo wexesha elide, kunye neeswitshi ze-voltage ephezulu azisetyenziswa rhoqo. Kolu hlobo lomsebenzisi, ukusebenza kweyunithi ephambili yeringi akugqibelelanga, kodwa kwanele. Ngolwakhiwo olukhulu lwasezidolophini, inani elikhulu lezakhiwo ezinkulu eziphakamileyo ziye zakhiwa, kwaye izitishi ezincinci zihlala zibekwe ezantsi. Ngokweemfuno zokukhusela umlilo, isitishi esincinci kunye nezixhobo zokusasazwa kufuneka "zingabi naoyile" kwaye zisetyenziswe ngokufanelekileyo ngokwendawo yokwakha. , Izixhobo ze-transformer kunye nokusasazwa kufuneka "zincitshiswe", ngoko ke iikhabhathi zenethiwekhi yeringi okanye ii-vacuum circuit breakers, ii-transformer zohlobo olomileyo, kunye nee-transformer zohlobo olomileyo zingene kwisakhiwo ngasinye. Ikhabhathi yenethiwekhi yeringi inesakhiwo esilula, ukusebenza okuthembekileyo nokukhuselekileyo, ulondolozo oluncinci, kunye neendleko zokusebenza eziphantsi. Xa kuthelekiswa neekhabhathi zokutshintsha ezixhotyiswe ngee-circuit breakers, ineengenelo ezibalaseleyo. Iyunithi ephambili yeringi ifuna ukuba iswitshi yomthwalo ibe nokusebenza okuphezulu kunye nobukhulu obuncinci. Kwavela uhlobo olutsha lweswitshi yomthwalo, nto leyo eyakhokelela kwinkqubela phambili yetekhnoloji yeyunithi ephambili yeringi. Iyunithi ephambili yeringi yanamhlanje ayipheleli nje ekusebenzeni kakuhle, kodwa ikwasebenza ngochungechunge. , nto leyo eyandise ububanzi bokusetyenziswa kwekhabhathi yenethiwekhi yeringi.
