SSD (SCB) surge backup protector daws qhov teeb meem hluav taws kub tshwm sim los ntawm SPD degradation thiab daim phiaj tsis ua hauj lwm (TOV), thiab daws qhov tsis ua hauj lwm ntawm SPD thaub qab tiv thaiv ntaus ntawv tshwm sim los ntawm kev ua haujlwm tsis zoo ntawm SPD thaub qab tiv thaiv ntaus ntawv los ntawm xob laim, thiab xyuas kom meej. tias cov cuab yeej tiv thaiv xob laim (SPD) Tsis muaj hluav taws kub, thiab cov khoom siv tiv thaiv xob laim tseem ua tau zoo; Nyob rau tib lub sijhawm, nws tuaj yeem kov yeej qhov kev tiv thaiv qhov muag tsis pom qhov teeb meem ntawm kev siv fuses lossis Circuit Court breakers raws li cov khoom siv sab nraud. Nws yog ib qho khoom siv zoo tshaj plaws rau kev hloov hluav taws xob SPD thiab voltage txwv SPD hauv cov tshuab hluav taws xob qis. .
Lub surge back-up protector yog ib yam khoom tshwj xeeb tsim thiab tsim raws li cov kev cai ntawm IEC 61643-4-43 hauv Tshooj 430.3:" Ua ntej lub Circuit Court ua rau muaj kev phom sij, yuav tsum siv cov khoom siv tiv thaiv overcurrent tsim nyog." Kuj tseem hu ua SPD surge protector mob siab rau kev tiv thaiv ntaus ntawv (SSD Cov khoom siv tiv thaiv tshwj xeeb rau cov khoom siv hluav taws xob qis qis) lossis SPD backup tiv thaiv (SCB Tshwj Xeeb Circuit Breaker /
Surge Protective Device Circuit Breaker).
Lub SSD (SCB) txuas nrog hauv cov kab nrog SPD Circuit Court, thiab muaj peev xwm tiv taus cov hluav taws xob siab. Qib T1 tuaj yeem ncav cuag li 25 kA (10/350μs), thiab T2 theem tuaj yeem ncav cuag 120 kA (8/20μs), thiab qhov seem hluav taws xob tsawg; Intelligently paub qhov xob laim tam sim no thiab lub zog zaus tam sim no ntws los ntawm SPD. Thaum SPD yog degraded los yog luv luv, SSD (SCB) raug txiav tawm sai sai los tiv thaiv SPD los ntawm hluav taws.
SSD (SCB) tau txais ib qho qauv tsim qauv ib leeg-chip, uas tuaj yeem sib phim txhua yam ntawm SPD hauv qhov hluav taws xob qis hluav taws xob. Nws muaj cov yam ntxwv ntawm qhov me me, siab rhiab heev, thiab muaj zog tawg muaj peev xwm, muab koj nrog zoo meej SPD thaub qab tiv thaiv kev daws teeb meem.
