Ulwakhiwo olupheleleyo lweSwitchgear

Ulwakhiwo Olupheleleyo lweSwitchgear (Thatha ikhabhinethi ye-vacuum circuit breaker efakwe embindini njengomzekelo)

Ngokuthatha iswitshi ye-JYN2-10(Z) yombane ophezulu njengomzekelo, isakhiwo sayo sinokwahlulwa sibe ngamacandelo amabini: ikhabhinethi kunye nemoto yesandla. Imoto yesandla yemoto yesandla ye-circuit breaker, izinto eziphambili zombane yi-circuit breaker (efakwe emotweni), iswitshi yokumisa umhlaba kunye nesihlalo soqhagamshelwano esingashukumiyo, njl.

Ikhabhinethi yahlulwe yangamacandelo amane azimeleyo ngeepleyiti zentsimbi ezisekelwe phantsi: igumbi lebhasi, igumbi lenqwelo yesandla, igumbi lezixhobo zokudlulisela, kunye negumbi lentambo. Icala elingasemva nelisezantsi lekhabhinethi liba ligumbi lentambo, apho kufakwa khona iintambo kunye neetransformer zangoku. Ngaphezulu kukho igumbi eliphambili lebhasi. Kukho izahlulo phakathi kwamacandelo ukuqinisekisa ukhuseleko ngexesha lokugcinwa. Phambi kwekhabhinethi kukho igumbi lokudlulisela kunye negumbi lenqwelo yesandla. Qhubeka usebenza. Ngomatshini wokuqhuba, itroli exhotyiswe nge-circuit breaker ihamba ibuyela umva nangaphambili kwireyili yesikhokelo. Ukutyhala ngaphakathi kungenza ukuba oonxibelelwano abaphezulu nabasezantsi abazimeleyo be-circuit breaker bafake kwisiseko soqhagamshelwano esingaguqukiyo ukuze kugqitywe uqhagamshelo lwesekethe; ngokuchaseneyo, xa i-circuit breaker iphula isekethe, khupha itroli ukuze wahlukanise oonxibelelwano abashukumayo nabazinzileyo. , Ukwenza umsantsa ocacileyo wokwahlukanisa, olingana nendima yeswitshi yokwahlukanisa. Usebenzisa i-carrier ezinikeleyo, itroli exhotyiswe ngee-circuit breakers inokutyhalelwa lula ngaphakathi okanye ikhutshwe kwikhabhinethi.

Xa i-circuit breaker ingasebenzi kakuhle okanye yonakele kakhulu, i-truck breaker trolley ekhethekileyo ikhutshwe emzimbeni wekhabhinethi ukuze igcinwe. Ingatshintsha i-circuit breaker trolley eseleyo, etyhalelwe emzimbeni wekhabhinethi.

2.1.1 Iimfuno eziSiseko

(1) Uyilo lweswitshi ye-voltage ephezulu kufuneka lwenze ukusebenza okuqhelekileyo, ukubeka esweni kunye nomsebenzi wokulungisa iswitshi ye-voltage ephezulu kukhuseleke kwaye kube lula. Umsebenzi wokulungisa uquka: ukuhlaziya amacandelo, ukuvavanya, ukufumana iimpazamo kunye nonyango;

(2) Kwiiparameter ezilinganisiweyo kunye nesakhiwo esifanayo kunye nesidingo sokutshintsha izinto kufuneka zitshintshiselane;

(3) Yokushenxiswa

Iswitshi yevolthi ephezulu yeendawo ezivulekileyo kufuneka itshintshiselwe ukuba iiparameter ezilinganisiweyo kunye nolwakhiwo lweendawo ezisuswayo ziyafana;

(4) kufuneka ihlolwe ngokwemiqathango yasekuhlaleni yokusetyenziswa kwayo;

(5) Liza kuzama ukuba liphucuke kwezobuchwepheshe kwaye libe nengqiqo kwezoqoqosho;

(6) Iimveliso ezintsha ezikhethiweyo kufuneka zibe nedatha yovavanyo ethembekileyo kwaye zifaneleke kuvavanyo.

2.1.2 Ukumiselwa kwesicwangciso esiphambili seluphu

Isekethe ephambili yekhabhinethi yokutshintsha yombane ophezulu ikwabizwa ngokuba ngumgca, ngokweemfuno zangempela zenkqubo yamandla kunye nenkqubo yokubonelela ngombane kunye nokusasazwa, imodeli nganye yesekethe ephambili yekhabhinethi yokutshintsha yombane ophezulu inamashumi amaninzi angaphantsi, amakhulu amaninzi, idla ngokubandakanya ezi ndidi zilandelayo: umkhombe, itanki yokulinganisa, ukuhlukaniswa, ikhabhinethi yenqwelo yokumisa umhlaba, iikhabhinethi ze-capacitor, ikhabhinethi yolawulo lombane oluphezulu (F - C ark), njl.

Indibaniselwano yesikimu sesekethe esiphambili seswitshi ukuze kuqwalaselwe le miba ilandelayo:

(1) ngokwedayagram yenkqubo ephambili kunye nobukhulu bayo bangoku bokusebenza kweluphu ephambili kunye nolawulo, ukhuseleko, umlinganiselo kunye nezinye iimfuno, khetha iskimu sesekethe esiphambili esihambelanayo sekhabhinethi yokutshintsha;

(2) Ukukhetha phakathi kweentlobo zemigca engenayo nephumayo kunye neswitshi.
