LOPS rau MV Bus Overvoltage Protection

Lub LOPS low-voltage bus overvoltage suppression device yog txuas ncaj qha mus rau lub tsheb npav, siv cov thev naus laus zis xws li cov tswj ceev ceev, cov hluav taws xob tsis muaj hluav taws xob tsis zoo, cov hluav taws xob siab tshaj qhov cuam tshuam, thiab kev tawm tsam kev tawm tsam. Nws yog scientifically xam thiab finely tsim. LOPS siv tag nrho cov volt ampere yam ntxwv zoo, muaj peev xwm thermal loj, thiab cov lus teb ceev ceev ntawm overvoltage interceptors, nonlinear resistors, thiab counterattack suppression khoom. Feem ntau, teeb tsa tus nqi ntawm LOPS ntawm 1.2 npaug ntawm qhov system theem voltage (customizable nyob rau hauv tshwj xeeb mob) tuaj yeem ua tiav cov txiaj ntsig zoo thaum lub sijhawm ua haujlwm.

LOPS yog txuas ncaj qha nyob rau hauv parallel mus rau lub busbar, siv technologies xws li ceev controllers, high-zog nonlinear resistors, overvoltage ncov interceptors, thiab counterattack suppression. Nws yog scientifically xam thiab finely tsim. LOPS them nyiaj rau qhov tsis txaus xws li SPD, kev tiv thaiv kev tiv thaiv overvoltage, thiab kev tiv thaiv lub peev xwm nqus, ua tiav cov teeb meem ntawm overvoltage ntawm qhov nruab nrab voltage lub ntsiab busbar.

cov khoom paub meej

Functional nta

• Siab zog nonlinear resistor nti txuam tshuab

Lub nonlinear resistor txais cov cuab yeej hluav taws xob tshwj xeeb thiab cov txheej txheem kaw tag nrho, nrog rau cov cua sov zoo thiab tiv thaiv kev ya raws, kev ua haujlwm ruaj khov, kev ua haujlwm ntev, thiab kev nyab xeeb thiab kev ntseeg tau.

• Overvoltage ncov txiav tshuab

Thaum lub sijhawm dhau los ntawm qhov hluav taws xob tshwm sim hauv qhov system, thaum tus nqi siab tshaj ntawm qhov hluav taws xob ntau tshaj 1.2 npaug ntawm qhov ntsuas hluav taws xob siab tshaj tus nqi, lub overvoltage ncov interceptor tam sim ntawd txiav tawm lub siab voltage nthwv dej lub taub hau, ua kom muaj kev nyab xeeb ntawm ntau yam khoom siv thauj khoom hauv qab busbar.

• Secondary pressure limiting technology

Tom qab kev ua haujlwm ntawm thawj theem voltage limiting unit, yog hais tias lub tsheb npav voltage tseem tshaj qhov tsim nyog tus nqi, LOPS cov cuab yeej yuav muab tso rau hauv lub overvoltage chopper kom ceev ceev lub tsheb npav voltage mus rau 1.2 zaug los yog tsawg dua.

• Tshuab teb ceev ceev

Qhov kev ncua sij hawm yog me me, thawj theem tsis muaj lus teb qeeb, thiab qib thib ob teb tsis pub dhau 2 milliseconds.Zoo yoj yoj cov yam ntxwv, lub sij hawm luv luv ntawm nonlinear resistors, active tiv thaiv, thiab kev tiv thaiv zoo.

• Overvoltage kaw tshuab

LOPS cov khoom siv hluav taws xob tsawg-voltage overvoltage suppression tuaj yeem kaw qhov tsis xws li tus naj npawb ntawm kev ua, lub sijhawm ua haujlwm, thiab lub tsheb npav voltage thaum ua haujlwm, muab lub hauv paus rau kev tshuaj xyuas kev ua haujlwm.
