LOPS for MV Bus Overvoltage Protection

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.

iinkcukacha zemveliso

Iimpawu ezisebenzayo

• Itekhnoloji yokulinganisa itshiphu yokumelana ne-nonlinear ephezulu yamandla

I-resistor engabonakaliyo ithatha iteknoloji ekhethekileyo yokutshatyalaliswa kobushushu kunye nenkqubo etywinwe ngokupheleleyo, kunye nokutshatyalaliswa kobushushu obugqwesileyo kunye nemiphumo yokukhusela umswakama, ukusebenza okuzinzileyo, ubomi benkonzo ende, kunye nokhuseleko nokuthembeka.

• Itekhnoloji yokusika i-overvoltage peak

Xa i-overvoltage edlulayo iyenzeka kwinkqubo, xa ixabiso le-peak ye-overvoltage lidlula amaxesha angama-1.2 ixabiso le-voltage elilinganiselweyo, i-interceptor ye-overvoltage peak ngokukhawuleza yenza ukunqumla intloko yamaza ombane aphezulu, iqinisekisa ukusebenza ngokukhuselekileyo kwezixhobo ezahlukeneyo zomthwalo phantsi kwe-busbar.

• Iteknoloji yokunciphisa uxinzelelo lwesibini

Emva kokusebenza kweyunithi yokunciphisa umbane wenqanaba lokuqala, ukuba amandla ombane ebhasi asagqitha kwixabiso elimiselweyo, izixhobo zeLOPS ziya kubeka i-chopper engaphezulu kwe-overvoltage ukunciphisa ngokukhawuleza umbane webhasi ukuya kumaxesha ayi-1.2 okanye ngaphantsi.

• Itekhnoloji yokusabela ngokukhawuleza

Ukulibaziseka kwesenzo kuncinci, inqanaba lokuqala alinayo impendulo yokulibaziseka, kwaye inqanaba lesibini liphendula ngaphakathi kwe-2 milliseconds. Iimpawu zokuphendula kakuhle kwe-wave wave, ixesha elifutshane lokuqhuba i-resistors nonlinear, ukhuseleko olusebenzayo, kunye nokusebenza kakuhle kokukhusela.

• Itekhnoloji yokurekhoda i-overvoltage

Isixhobo se-LOPS esine-voltage ephantsi yebhasi yokucinezela i-voltage overvoltage inokurekhoda ngokuzenzekelayo iiparamitha ezifana nenani lezenzo, ixesha lesenzo, kunye nombane webhasi ngexesha lesenzo, ukubonelela ngesiseko sohlalutyo lobugcisa.
