Yintoni Ukusebenza kunye Nokusetyenziswa kweSwitshi ye-Loadbreak ye-38kV 630A Type Four-Position Oil-Insulated Loadbreak?

Yintoni iIsitshixo seLoadbreak?
I-Loadbreak Switch yiswitshi yombane eyenzelwe ngokukodwa ukuphazamisa ukuhamba kombane ngokukhuselekileyo ngaphandle kweentlantsi okanye ii-arcs eziyingozi. Ukusetyenziswa okunjalo kubaluleke kakhulu kwiivolthi eziphezulu, njengakwiinkqubo ezininzi zokusasaza amandla. Le switshi ye-loadbreak ye-38kV 630A ijongene nevolthi ukuya kuthi ga kwi-38000V kunye nemisinga ephezulu njenge-630 amperes. Ngoko ke, ikwafumana ukubaluleka kwiinkqubo ezinkulu zombane.

Ukuqonda Iziseko zeSwitshi ye-Loadbreak ye-38kV 630A
Ezi zilandelayo ziimpawu zeswitshi yokuvula umthwalo ye-38kV 630A:

• Umthamo weVolthi ephezulu: Umthamo weVolthi ephezulu wenza le switshi ifaneleke kwizicelo zemizi-mveliso nezorhwebo.

• Ioyile yokukhusela ubushushu: Isebenzisa ioyile ye-transformer njengesithinteli-bushushu esinceda ekuthinteleni iingxaki zombane kunye nokucima kwe-arc.

• Ukulula kokusebenza: Iswitshi yenzelwe ukuba ibe neendawo ezimbini, i-VULIWE ne-VULIWE.

• Uqwalaselo oluguquguqukayo: Ingafakwa kwiinkqubo ezahlukeneyo zokusasazwa kwamandla, njengenkqubo yokusasazwa kwamandla okugqibela kunye nenkqubo yeringi-network.

Isebenza njani i-38kV 630A Loadbreak Switch?

Indima ye-Transformer Oil
Kule switch, ioyile yetransformer idlala indima ebaluleke kakhulu. Oku kungenxa yokuba idlala indima embaxa:

• Ukuthintela ubushushu: Ngenxa yokuba ioyile isebenza njengesithinteli-bushushu, umbane ngaphakathi kwiswitshi awuyi kuvuza ngaphandle, nto leyo ebangela ukuba kubekho i-short circuit.

• Ukuphela kwe-Arc: Ukuba kukho i-arc yombane eyenziweyo xa iswitshi icinyiwe, ioyile iya kunceda ekucimeni i-arc, nto leyo eyenza inkqubo yokutshintsha ikhuseleke ngakumbi.

Indlela Yokusebenza
I-Loadbreak Switch isebenza phantsi komgaqo olula kakhulu.

Isikhundla sokuvula: Ukujika kwesiphatho ngokwewotshi, ngokusebenzisa iswitshi, kudibanisa isekethe yombane, ngaloo ndlela kudlula umbane.

Indawo Yokucima: Isibambo esijikwe kwicala elichasene newotshi sinqamla isekethe kwindawo yokucima, ngaloo ndlela siyeka ukuhamba kombane. Oku kwenziwa ngaphakathi kwerediyasi ejikelezayo engama-90 degrees, kunceda ekusebenziseni iswitshi ngokuchanekileyo nangokukhuselekileyo.

Izicelo zeLoadbreak Switch
I-38kV 630A Loadbreak Switch inezicelo ezininzi kwaye ngenxa yoko ingasetyenziswa kwiindawo ezahlukeneyo, kuquka:

1. Iinkqubo zoSasazo lwaMandla oMbane
Ezi ziinkqubo ezibonelela ngombane kumthengi wokugqibela. Umzekelo, izindlu okanye ezinye iindawo. Iswitshi yokuvula nokuvala umbane ibalulekile ekuvuleni nasekuvaleni umbane nanini na xa kufuneka njalo.

2. Iinkqubo zoSasazo lwaMandla eRing-Network
Ngaphakathi kwenkqubo yeringi-network, ukuhamba kombane kujikelezile. Ulwakhiwo olunikiweyo luvumela izibonelelo zeendlela zokuxhasa umbane. Ngamanye amazwi, ukuba enye indlela yonakaliswa, ke uncedo lokufikelela kubasebenzisi kuyaqhubeka ngenye indlela. Iswitshi yokuvula umbane iphatha ezo nkqubo.

Izinto ekufuneka ziqwalaselwe xa kufakwa kunye nokugcinwa
Ukufakelwa nokugcinwa okufanelekileyo kubaluleke kakhulu ekusebenzeni ngokukhuselekileyo nangokusebenzayo kweswitshi yokuvula umthwalo.

Amanyathelo okufakela

• Ukuhlolwa kweNdlela yokusebenza: Ukuhamba kakuhle kweswitshi ngokuchanekileyo kufanele kuhlolwe ngaphambi kokufakwa.

• Ukomisa: Iswitshi kufuneka yomiswe kubushushu obuyi-65±5ºC kangangeeyure ezingama-24 ukuze isebenze ngokuchanekileyo.

• Ukuhlolwa kokugqibela: Umsebenzi "wokuvula" kunye "nokuvala" kufuneka wenziwe emva kokufakwa; oku kuya kuqinisekisa ukuba iswitshi isebenza kakuhle kwaye izibonakaliso zendawo zifanelekile.

Iingcebiso Zokulungisa
• Hlola iswitshi rhoqo ukuba ayigugi okanye yonakele.
• Jonga inqanaba leoyile kwaye uqinisekise ukuba akukho kuvuza.
• Kufuneka kuvavanywe rhoqo iswitshi ukuqinisekisa ukuba iyakwazi ukuthwala ngokukhuselekileyo umbane olinganisiweyo.
Amanyathelo okhuseleko
Ukhuseleko lolona hlobo lubalulekileyo lokuphatha izixhobo ezisebenzisa umbane ophezulu. Nazi ezinye iingcebiso zokhuseleko ezifunekayo:

• Umbane Olinganiselweyo Kuphela: Yile nto ithethwayo- kuphela umbane olinganiselweyo omele uvulwe okanye uvalwe ngeswitshi yokuvula umthwalo. Ukusebenza ngaphandle komthamo wawo olinganiselweyo kunokukhokelela lula kwiimeko eziyingozi.

• Sebenzisa Izixhobo Ezigqunyiweyo: Ingalo yokusebenza egqunyiweyo ngokukodwa kufuneka isoloko isetyenziswa ukulawula iswitshi. Oku kukugcina ukhuselekile kwiingozi ezininzi eziyingozi ngelixa usebenzisa izixhobo ezinjalo.

• Iinkqubo zongxamiseko: Kufuneka kubekho iinkqubo zongxamiseko ezicacileyo ekufuneka zilandelwe xa kukho ukungasebenzi kakuhle kombane kunye neengozi.

Isiphelo
I-38kV 630A ene-oyile efakwe i-insulation kwiindawo ezineiswitshi yokuvala umthwalosisixhobo esibaluleke kakhulu esisetyenziswa ekulawuleni umbane ombane ophezulu. Uyilo lwaso lokukhusela ioyile yetransformer kunye nokuphela kwe-arc luqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo.
