UkuKhuselwa koMbane kunye nokugqithiswa kwe-Overvoltage kuMandla aPhambili

I-GPAS sisixhobo sokukhusela umbane esisebenza ngeendlela ezininzi nesisebenzayo esidibanisa umhlaba onokubakho wokucinezela uhlaselo kunye nokukhusela i-arc ye-fault. Inokunciphisa kakhulu umonakalo kunye neempembelelo zokuhlaselwa komhlaba okunokubakho kunye neempazamo ze-arc kwisixhobo xa zibonakaliswe kwiingozi zombane.

Xa umbane othe ngqo wenzeke, intonga yombane okanye inethiwekhi yokukhusela umbane idibaniswe, kwaye umbane onamandla okhoyo ugeleza kwigridi yomhlaba. Xa imigca yevoltage ephezulu ifumana i-overvoltage yombane, umbane wangoku uqukuqela kwigridi yomhlaba ngokubamba umbane. Xa izixhobo eziphazamisayo ezinamandla ezifana noomatshini be-welding zisebenza, ukuphazamiseka okunamandla okukhoyo okwenziwa ngabo kuya kuphinda kugeleze kwigridi yomhlaba. Isiseko esinamandla sangoku sinokubangela ukulahleka kwedatha, ukusetyenziswa kakubi kwezixhobo, ukukhubeka kwezixhobo, ukonakala kwe-insulation okanye ukutshisa kwiinkqubo zokubonelela umbane ophantsi.

I-GPAS inokuthembeka okuphezulu kunye nexesha elifutshane lesenzo, elinokuthi likwazi ukwahlula ngokufanelekileyo imisinga yombane ye-frequency high-frequency, ukuthintela imisinga yombane ekuhlaseleni inethiwekhi ekhuselayo ekhuselayo ukusuka kumnatha wokukhusela umbane wokumisa umbane, kwaye uphephe ngokufanelekileyo ukwenzeka kweengozi zemveliso yokhuseleko ezifana nemililo kunye nokudubula.

Isixhobo se-LOPS esine-low-voltage bus overvoltage suppression sidityaniswe ngokuthe ngqo ngokuhambelana nebhasi, sisebenzisa ubugcisa obufana nabalawuli abakhawulezayo, abachasi be-energy high-energy nonlinear, i-overvoltage peak interceptors, kunye ne-counterattack suppression. Ibalwa ngokwenzululwazi kwaye iyilwe kakuhle. I-LOPS isebenzisa ngokupheleleyo iimpawu ze-volt ampere ezigqwesileyo, umthamo omkhulu we-thermal, kunye nesantya sokuphendula ngokukhawuleza se-overvoltage interceptors, izichasi ezingezizo, kunye nezixhobo zokucinezela uhlaselo. Ngokuqhelekileyo, ukubeka ixabiso lesenzo se-LOPS ngamaxesha e-1.2 i-voltage yesigaba senkqubo (i-customizable kwiimeko ezikhethekileyo) inokufezekisa iziphumo ezilungileyo ngexesha lokusebenza.

I-LOPS iqhagamshelwe ngokuthe ngqo ngokuhambelana ne-busbar, isebenzisa itekhnoloji efana nabalawuli abakhawulezayo, abachasi be-energy high-nonlinear, i-overvoltage peak interceptors, kunye nokunyanzeliswa kwe-counterattack. Ibalwa ngokwenzululwazi kwaye iyilwe kakuhle. I-LOPS ihlawulela iintsilelo ezifana ne-SPD, ukhuseleko oludityanisiweyo lokugqithiswa kwamandla, kunye nokufunxa amandla okumelana, ukusombulula ngokupheleleyo ingxaki yokugqithisa kakhulu kwi-medium voltage main busbar.

I-35kV ~ 6kV imigca engaphezulu idla ngokufakela izibambi ze-ZnO. Kukho iimpazamo ezikhokelela ekukhubekeni, ekuqhawukeni komgca kunye nokuphuma mnyama.
Ukukhuselwa koMbane oMtsha kuNxibelelwano oluNtsha (LOPT) lusekwe kufutshane nesiphumo secathode, inqanaba elininzi lesithuba esifutshane se-arc yokuvuthela kunye nokucima itekhnoloji, ukutyhoboza kwiimpawu ezibuthathaka zombane wababambeli be-ZnO, isebenzisa umgaqo wokuvuthela nokucima i-arc yamagumbi amaninzi, uyilo olukhethekileyo lolwakhiwo ukolula ukucofa injongo ye-arc eyongezelelweyo, kunye nokwandisa injongo ye-arc eyongezelelweyo. ukucima.

I-LOPT ineenzuzo ezifana nokhuseleko, ukuthembeka ngakumbi, ubomi obude, kunye nokugcinwa okuncinci. Inokukhulula ngokukhawuleza amandla ombane, ithintele ukugqabhuka kombane kunye nokukhubeka, kwaye inemisebenzi yolondolozo kunye nokuzicoca.
