Siyini isivikelo sokuhlinza? Isivikeli sokuhlinza, esibizwa nangokuthi isivikeli sombani, iyisisetshenziswa sikagesi esihlinzekayo ukuvikelwa kokuphepha kwemishini ehlukahlukene ye-elekthronikhi, amathuluzi, nemigqa yokuxhumana. Lapho i-spike current noma i-voltage ikhiqizwa ngokuzumayo kumjikelezo kagesi noma isifunda sokuxhumana ngenxa yokuphazamiseka kwangaphandle, umvikeli ohlinzayo angakwazi ukuqhuba futhi shunt ngesikhathi esifushane kakhulu, ukuze uvimbele ukuqhuma ekulimazeni ezinye izinto zokusebenza ku isifunda. Kungani sidinga umvikeli wokuhlinza? Izinhlekelele zombani zingenye yezinhlekelele zemvelo ezimbi kakhulu. Njalo ngonyaka, zikhona izingozi ezingenakubalwa kanye nokulahlekelwa kwempahla okubangelwa izinhlekelele zombani emhlabeni. Nge ukusetshenziswa okukhulu kwemishini edidiyelwe kagesi kanye ne-microelectronic, lapho ziya ngokuya zilimaza amasistimu nemishini ebangelwa ukugcwala kombani futhi umbani we-electromagnetic pulses. Ngakho-ke, kubaluleke kakhulu ukuxazulula umbani izinkinga zokuvikela izinhlekelele zezakhiwo kanye nezinhlelo zolwazi lwe-elekthronikhi ngokushesha nje kungenzeka. Ngezidingo eziqinile ngokuya ngemishini ehlobene yokuvikela umbani, ukufakwa kwezivikeli zokuhlinza ukuze kucindezelwe ukushuba kanye nokugcwala ngokweqile kwamandla umugqa, futhi i-overcurrent emgqeni wokukhipha isibe yingxenye ebalulekile yesimanje ubuchwepheshe bokuvikela umbani. Sisebenza kanjani isivikeli sokuhlinza? Umgomo wokusebenza womkhiqizo wethu uthi: uma kungekho overvoltage, umkhiqizo ungaphakathi isimo esingaphandle, futhi ukumelana akupheli. Lapho kukhona overvoltage ohlelweni, the umkhiqizo usesimweni esivaliwe futhi ukumelana kuncane ngokungenamkhawulo, futhi kwangaphakathi izingxenye zizobamba i-voltage phakathi kobubanzi obuthile. , Umsinga ogeleza phakathi kwe umugqa uzomuncwa futhi ukhululwe. Ngemva kokuqedwa kokukhishwa, umkhiqizo uyabuya esimweni sokumelana okuphezulu (isimo esinqanyuliwe) ukuze singabi neminye imiphumela imishini. Yimaphi amapharamitha abalulekile wesivikeli sokuhlinza? 1.I-voltage eqhubekayo yokusebenza ephezulu (Uc): Isho inani eliphezulu elisebenzayo le-AC I-voltage noma i-DC voltage engasetshenziswa ngokuqhubekayo ku-SPD. I-2.I-Max discharge current(I-Imax):Ibhekisela kumthamo omkhulu okhishwa yi-SPD ukumelana kanye usebenzisa igagasi lamanje elingu-8/20μs ukuze libe nomthelela ku-SPD. 3.Minimun discharge current(In):Isho i-dicharge current lapho i-SPD ingasebenza khona. ngokujwayelekile 4.Izinga lokuvikela: Inani eliphakeme kakhulu le-voltage phakathi kwamatheminali e-SPD ku ubukhona be-impulsive overvoltage.lt iyipharamitha eyisisekelo yokukhetha kahle I-SPD; i-akhawunti yakho kufanele ithathwe maqondana nomfutho we-voltage wemishini okufanele ibe kuvikelwe. Wenzani uTHOR? Selokhu yasungulwa, i-Thor ibilokhu ihambisana nombani wamazwe ngamazwe izinga lokuvikela (IEC61643-1) futhi lizibophezele ekukhiqizeni nasekucwaningeni ukuthuthukiswa kwezivikeli zokuhlinza. Imikhiqizo ihlanganisa izivikeli zokuhlinza amandla endlini, abavikeli bokuhlinzwa be-photovoltaic, abavikeli bokuhlinzwa kwezimboni, nabavikeli bokuhlinzwa kwamanethiwekhi, izivikeli zesignali, njll. ukunikeza abathengi izinketho ezingcono zombani imikhiqizo yokuvikela.
