UMGAQO OYISEKILEYO WOKUTSHINTSHA UMTHWALO WE-VOLTAGE HEAD

Iswitshi yomthwalo we-high-voltage iyazamkela ngokupheleleyo iingenelo zokucima i-arc zetyhubhu yeswitshi ye-vacuum kunye nendlela yokusebenza ehambelanayo. Ekubeni iswitshi yomthwalo we-high-voltage ingenako ukuphula i-short-circuit current, ilula ngokwesakhiwo kwaye ifanelekile kwiziganeko ezine-current encinci kunye nezenzo eziqhelekileyo. Kukho iiswitshi ezimbini eziqhelekileyo zomthwalo we-high voltage: uhlobo lwangaphakathi kunye nohlobo lwekholamu yangaphandle.

Kukho iintlobo ezininzi zeeswitshi zomthwalo we-high-voltage, kwaye isakhiwo sinokwahlulwa sibe ziiswitshi zomthwalo we-oyile ephezulu, iiswitshi zomthwalo we-vacuum high-voltage, iiswitshi zomthwalo we-sulfur hexafluoride ephezulu, iiswitshi zomthwalo we-high-voltage ezivelisa igesi kunye neeswitshi zomthwalo we-high-voltage ezicinezelweyo emoyeni, njl.njl.; ngokwendlela yokusebenza, yahlulwe ngokwendlela yokusebenza ngesandla. Kukho iintlobo ezimbini zeeswitshi zomthwalo we-high-voltage kunye neeswitshi zombane ze-high-voltage. Ezi mveliso zigxile kwinethiwekhi yokusasaza, njengeekhabhathi zenethiwekhi yeringi. Okwangoku, iiswitshi zomthwalo we-high-voltage ze-vacuum zithandwa ngakumbi, kwaye iiswitshi zomthwalo we-high-voltage zixhotyiswe ngee-fuses kunye nezinye izixhobo. Ingqwalasela engakumbi inikwe ekuqhubekeni komsebenzi wokuguqula inethiwekhi. Oku kulandelayo kuchaza iimpawu zesakhiwo kunye nemigaqo esisiseko yeeswitshi ezimbini eziqhelekileyo zomthwalo we-high-voltage.

Iswitshi yomthwalo we-voltage ephezulu ifakwe ngokupheleleyo kwi-bracket yayo esisigxina. Indlela yayo yokusebenza kufuneka isebenze ngendlela echaziweyo, ngakumbi, ukuba indlela yokusebenza yeyombane okanye ye-pneumatic, ukusebenza kwayo kufuneka kwenziwe nge-voltage encinci okanye uxinzelelo lomoya oluncinci, ngokwahlukeneyo, ngaphandle kokuba ukuphazamiseka kombane kuya kuchaphazela iziphumo zovavanyo. Kwimeko yokugqibela, i-voltage okanye uxinzelelo lomoya ngexesha lokusebenza kweswitshi yomthwalo kufuneka kukhethwe ngaphakathi koluhlu oluchaziweyo ukuze kube nesantya esiphezulu kunye nokusebenza okuphezulu kokucima i-arc xa oonxibelelwano bahlulwe. Kufuneka kuboniswe ukuba i-switch-disconnector isebenza ngokwanelisayo phantsi kweemeko ezingenamthwalo phantsi kweemeko ezingentla. Ukuba kunokwenzeka, idatha efana nokuhamba koqhagamshelwano oluhambayo kufuneka irekhodwe. Iiswitshi zomthwalo ezingasetyenziswanga ngesandla zinokusebenza ngokuvala ulawulo olukude.

1. Kufuneka kuqwalaselwe ngokufanelekileyo ukukhethwa koqhagamshelo lwecala eliphilayo. Xa iswitshi yomthwalo yenzelwe ukuqhagamshelwa kumbane ukusuka kumacala omabini, kwaye uyilo lokwenyani lwecala elinye leswitshi yomthwalo lwahlukile kuyilo lwelinye icala, umbane wesekethe yovavanyo kufuneka uqhagamshelwe. kwicala elibonisa iimeko zokusebenza ezinzima kakhulu zeswitshi yomthwalo. Kwimeko yokuthandabuza, inxalenye yomsebenzi kufuneka yenziwe ngamandla aqhagamshelwe kwelinye icala leswitshi yomthwalo, kwaye enye inxalenye yomsebenzi kufuneka yenziwe ngamandla aqhagamshelwe kwelinye icala leswitshi yomthwalo.

2. Uvavanyo lokwenza nokwaphula iswitshi yomthwalo we-high-voltage enezibonda ezintathu esebenza ngexesha elinye yipali nganye luza kwenziwa kwisigaba sesithathu ngaphandle kokuba kuchazwe ngenye indlela.

Uvavanyo lokwenza nokwaphula iswitshi esineepali ezintathu esinokusebenza kwepali ngepali (eyenziwe ziiswitshi ezintathu ezineepali enye ezineepali eziphezulu) kufuneka zenziwe ngesigaba esinye, ngaphandle kovavanyo lokwaphula imithwalo oluneemfuno ezizodwa.

3. Ngaphandle kweeswitshi zomthwalo ezizaliswe ziswitshi zomthwalo olulwelo okanye igesi kunye ne-vacuum load, ukuba kukho ukusasazeka okukhulu kwelangabi okanye kwesinyithi, kunokufuneka kusetyenziswe isikrini sesinyithi esibekwe kufutshane neendawo eziphilayo kwaye kude nazo ngexesha lovavanyo. Umgama wokhuseleko oluchazwe kwifektri. Izikrini zesinyithi, iibrakethi kunye nezinye iindawo ezihlala ziphantsi komhlaba kufuneka zigqunywe ngobushushu emhlabeni kwaye ziqhagamshelwe enye kwenye emva koko ziqhagamshelwe kwisixhobo esifanelekileyo sokumisa umhlaba ukubonisa ukuba kukho ukuvuza okukhulu komhlaba.
