Ulwakhiwo lulonke lweSwitchgear

Ulwakhiwo lulonke lweSwitchgear (Thatha ikhabhinethi yevacuum breaker yesekethe exhonywe embindini njengomzekelo)

Ukuthatha i-JYN2-10 (Z) i-switchgear ephezulu yombane njengomzekelo, isakhiwo sayo sinokwahlulwa sibe ngamacandelo amabini: ikhabhinethi kunye nemoto yesandla.I-Handcar ye-handcar ye-circuit breaker handcar, iinqununu eziphambili zombane ziyi-circuit breaker (efakwe kwimoto), i-grounding switch kunye ne-solated static contact seat, njl.

Ikhabhinethi yahlulwe yangamacandelo amane azimeleyo ngeepleyiti zentsimbi ezisekelwe phantsi: igumbi lebhasi, igumbi lenqwelo yesandla, igumbi lesixhobo sokuhambisa izixhobo, kunye negumbi lekhebula. Icala elingasemva nasezantsi lekhabhinethi liba ligumbi lekhebula, apho iintambo kunye nabaguquli bangoku bafakwe. Ngaphezulu kwayo kukho igumbi lebhasi eliphambili. Kukho izahlulo phakathi kwamacandelo ukuqinisekisa ukhuseleko ngexesha lolondolozo. Ngaphambi kwekhabhinethi kukho igumbi lokudlulisa kunye negumbi lokuhamba ngesandla. Qhubeka nomsebenzi. Ngendlela yokuqhubela phambili, itroli exhotyiswe nge-breaker circuit ihamba ngasemva naphambili kumzila wesikhokelo. Ukutyhala ngaphakathi kunokwenza abafowunelwa abaphezulu nabasezantsi ababodwa abahambayo be-breaker sekethe bafake kwisiseko soqhagamshelwano esizimeleyo esisisigxina ukugqiba uqhagamshelwano lwesekethe; ngokuchaseneyo, xa i-breaker circuit iphula isiphaluka, yikhuphe i-trolley ukuze ihlukanise abafowunelwa abahambayo kunye nabazinzileyo. , Ukwenza umsantsa ocacileyo wokuzihlukanisa, olingana nendima yokutshintsha okukodwa. Ukusebenzisa umthwali ozinikeleyo, i-trolley exhotyiswe ngee-breakers zesekethe inokutyhalwa ngokulula okanye ikhutshwe ngaphandle kwekhabhinethi.

Xa umaphuli wesekethe ukusilela kakhulu okanye umonakalo, okufanayo kunokusebenzisa itroli ekhethekileyo yelori yesekethe yatsalwa ngaphandle kwekhabhinethi ukuze igcinwe.

2.1.1 IiMfuno eziSisiseko

(1) Uyilo lwesixhobo sokutshintsha amandla ombane aphezulu kufuneka lwenze ukusebenza okuqhelekileyo, ukubeka iliso kunye nomsebenzi wogcino lwesixhobo sokutshintsha amandla ombane aphezulu ukhuseleke kwaye ube lula. Umsebenzi wogcino ubandakanya: uhlengahlengiso lwamacandelo, uvavanyo, ukufumana iziphene kunye nonyango;

(2) Kwiiparamitha ezilinganisiweyo kunye nesakhiwo esifanayo kunye nesidingo sokutshintsha amacandelo aya kutshintshwa;

(3) Yeyokususwa

I-switchgear ephezulu ye-voltage yamacandelo avulekileyo iya kutshintshwa ukuba iiparitha ezilinganisiweyo kunye nesakhiwo seendawo ezikhutshwayo ziyafana;

(4) iya kuhlolwa ngokwemiqathango yendawo yokusetyenziswa;

(5) Iya kuzama ukuba phambili ngokwethekhinoloji kunye nengqiqo kwezoqoqosho;

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

2.1.2 Ukumiselwa kweskim se-loop esingundoqo

Isekethe ephambili yekhabhathi yokutshintsha kwamandla ombane aphezulu ikwabizwa ngokuba ngumgca, oko kuhambelana neyona mfuneko yenkqubo yamandla kunye nonikezelo lwamandla kunye nenkqubo yokuhambisa, imodeli nganye yeskim sesekethe yekhabhathi yokutshintsha kwamandla ombane aphezulu inamaninzi angaphantsi, amakhulu amaninzi, ngokuqhelekileyo ibandakanya ezi ndidi zilandelayo: umkhombe, itanki yokulinganisa, ukwahlukana, ukumisa ikhabhathi yesandla, iikhabhathi ze-capacitor, i-high-voltage yolawulo lwe-C, i-C capacitor control (ikhabhathi yombane)

Switchgear main circuit iskimu indibaniselwano ukuqwalasela le miba ilandelayo :

(1) ngokomzobo wenkqubo ephambili kunye ne-loop ephambili esebenzayo ubungakanani bangoku kunye nolawulo, ukhuseleko, umlinganiselo kunye nezinye iimfuno, khetha isicwangciso sesekethe esihambelanayo sekhabhinethi yokutshintsha;

(2) Ukukhethwa phakathi kweentlobo zemigca engenayo kunye nephumayo kunye ne-switchgear.
