Surge protector - yog dab tsi? Surge protector rau computer

Ib txhia computers yog kev cob cog rua ncaj qha mus rau lub network los ntawm cov qhov hluav taws xob. Tag nrho cov kws txawj nyob rau hauv ib lub suab hais txog cov inadmissibility ntawm xws li ib txiav txim vim hais tias ntawm lub qhov hwj chim-line surges. Yuav kom tiv thaiv koj tus kheej lub computer los ntawm cov pliaj overloads, siv surge protectors. Nyob ntawm seb lawv hom, lawv yuav tau mus ntxuav li hwj chim surges. Raws li ib tug tshwm sim, lub processor muaj peev xwm mus kav ntau lub xyoo thiab tsis hlawv. Tsis tas li ntawd, ib tug surge protector rau computer safeguard tiv thaiv loads kev cob cog rua hais lus, saib, printers, thiab lwm yam pab kiag li lawm.

Lawv ua txuj tsa ib tug dog dig surge protector hwj chim sawb, muaj raws ntawm nyob thiab keyboards. Txawm li cas los, nws yog tau smooth tawm lub surges thiab tshem tawm cuam uas tsim lub network.

Vim li cas peb yuav tsum tau ib tug surge protector?

Muaj ntau zem txog cov surge protector, "ua li cas nws yog li cas thiab nws yog rau" Koj yuav tsum tau mus ntsib nrog qhov kev tshawb xav. Tus tam sim no ntws los ntawm lub network nyob rau hauv tsev, yog nce mus nce los thiab yog dej num raws li ib tug sine yoj. Nws yog tau los ntawm lo lus "sine yoj", uas zoo li ib tug laim ntoom kab. Lub voltage rau lub network, raws li zoo raws li lub yoj yog lossi zuj zus lawm thiab ua. Du hloov mus hloov los tshwm sim nyob rau hauv ntau ntawm -300 mus +300 volts.

Yog hais tias koj saib tam sim no tsis nyob rau hauv lub nplos, koj yuav saib tau loj surges thiab voltage amplitude. Tag nrho cov impulses yuav tau ua lub khoom vaj khoom tsev nyob rau hauv lub chav tsev yog kiag li unsuitable rau ntxiv siv. Feem ntau cov feem ntau txom nyem audiotsentr, televisions thiab, ntawm chav kawm, computers.

Yuav ua li cas xaiv ib tug surge protector?

Yuav kom tiv thaiv koj lub computer nyob rau hauv lub tsev yuav tsum tau xaiv high-zoo surge protector. Tus nqi ntawm tus txheej txheem qauv yog nyob ib ncig ntawm 100 rubles. Txawm li cas los, lawv yuav tsis lav ib theem siab ntawm kev tiv thaiv ntawm tus kheej computers. Surges tej zaum tshwm sim heev, yog li ntawd koj yuav tsum tau xaiv ib tug ntau haib network lim. "Yuav ua li cas yog nws thiab yuav ua li cas los xaiv nws?" - ib lo lus nug uas nyiam ntau.

Tus nqi ntawm cov ntaus ntawv no yuav twv yuav raug hu muaj ntau tshaj li 100 rubles. Thaum koj xaiv ib tug network lim khw koj yuav tsum tau paub txog cov kev xaiv uas teev tseg los ntawm lub chaw tsim tshuaj paus rau hauv lub ntim. Feem ntau nws yog hais txog rau qhov ntev ntawm lub cable, lub voltage mem tes cuam tshuam, maximizing Limiter, raws li zoo raws li tus xov tooj ntawm muaj nyob. Cable loj yuav tsum tau xaiv raws li lub tej yam kev mob nyob rau hauv uas lub computer siv. Yog hais tias nws yog nyob deb deb ntawm lub phab ntsa, nws yuav tsum tau muab, thiab xaiv ib tug loj cable. Qhov loj tshaj plaws nyob rau hauv cov ntaub ntawv no, nws muaj kev ruaj ntseg mus nkaum nws. Needless hais, cable puas yuav ua tau kom ib tug luv luv Circuit Court nyob rau hauv tag nrho cov tsev. Tsis tas li ntawd, yog hais tias nws muaj ib yam dab tsi mus ncuav rau, nws yuav ua nyob rau hauv ib tug system kev sib tsoo. Uas hais tias, nws yog zoo dua mus xaiv tus network cable yog loj thiab teem nws kaw rau ntawm cov phab ntsa. Nyob rau hauv cov ntaub ntawv no kev nkag yuav tsum muaj. Nrog kev pab los ntawm sau clips remnants ntawm cable uas koj yuav tsum sau thiab sau ua ke. Nyob rau hauv cov ntaub ntawv no, nws yuav siv sij hawm ib tug tsawg kawg nkaus ntawm qhov chaw thiab muaj peev xwm yuav siv tau kiag li yam xyuam xim. Manufacturers feem ntau tsim cables xws li nyob rau hauv loj los ntawm 2 mus rau 5 meters. Nyob rau hauv Feem ntau, qhov no yog txaus rau koj mus cuag tag nrho cov pab kiag li lawm. Lub parameter ntawm impulse suab nrov nyob rau hauv lub chav 3500 rau 10000 A. Qhov zoo tshaj plaws network lim yuav muaj ib tug siab npaum li cas. Thaum yuav ib tug surge protector yuav tsum xyuam xim rau cov nyiaj pab ntau tshaj tam sim no nws tsis yog hauv qab no 10 A.

ua Surge

Muaj ntau ntau yam uas yuav nws thiaj li ua rau cia li undesired jumps mus rau ib tug network lim. "Ua li cas nws yog thiab yuav ua li cas sib ntaus sib tua nws?" - ib lo lus nug uas nyiam ntau. Ua ntej ntawm tag nrho lawv yog tshwm sim los ntawm kev siv ntawm lub hwj chim tau txais kev pab. Yog hais tias koj nquag siv lawv tshwm sim overload, thiab kev nyuaj siab pib Dhia paj paws. Qhov thib ob feem ntau ua tsis yog hais txog rau tib neeg ua si. Nws yog ib qho atmospheric overvoltage. Tu siab, cov huab cua ua rau nws tus kheej kev kho me ntsis, thiab qhov no yuav tsum tau suav hais tias. Tsis tas li ntawd surges yuav tshwm sim vim malfunction ntawm transformer substations. Raws li ib tug txoj cai, lawv luv luv-Circuit Court tshwm sim, uas ua rau txoj dab. Tag nrho cov no pom nws thiaj nyob rau hauv lub chaw ua hauj lwm ntawm lub zuag qhia tag nrho tsev network.

Hloov mus hloov los nyob rau hauv lub network

Hloov mus hloov los nyob rau hauv lub network yog ib tug complex muaj nuj nqi. Nws yuav tuaj raws li ib tug txheej ntawm sine tsis. Txhua yam ntawm lawv nws muaj nws tus kheej pes tsawg zaus. Ib tug tag nrho system nws teev ib lub amplitude, li ntawd, lub sine yoj daim ntawv nyob rau hauv lub sau ua ib pawg. Nyob rau hauv kev txiav txim hais tias tus voltage yog ruaj khov, nws xav tau kev pab tsuas yog ib sinusoid uas muaj ib zaus ntawm 50 Hertz. Lub amplitude yuav nyob ib ncig ntawm 310 volts. Cov kev sib tw nyob rau hauv qhov ntsiab lus teb yog mus tshem tawm tag nrho cov lwm yam sine tsis hais tias muaj tej yam nyob rau hauv lub network. Ua li no, lawv yuav tsum tau nyob rau hauv txhua txoj kev uas suppress los thaiv kev nkag tau mus rau lub hwj chim-consuming khoom.

aperiodic suab nrov

Muaj kuj aperiodic suab nrov uas cuam tshuam rau voltage nyob rau hauv lub system. Nyob rau hauv sib piv rau sine tsis, lawv tsis yooj yim rau koj twv seb thiab thaiv. Nyob rau hauv kev aperiodic pulsed cuam tau nyob rau hauv yob. Lub system lawv tshwm sim thiab zuj zus lawm tso nyob rau hauv ib tug heev luv luv lub sij hawm ntawm lub sij hawm. Muaj ntau surge protectors yuav tau tiv nrog xws li shocks thiab mus suppress lawv.

Yuav ua li cas yog ib surge protector?

Resistors yuav tsis muaj feem mus rau lub hom tam sim no uas kis tau los ntawm lawv. Txawm li cas los, inductance yog xav muaj tej yam uas voltage zaus. Cov tag nrho taw tes yog reactance muaj peev xwm. Thaum lub kauj yog energized nrog ib tug high school cov zaus, nws kuj yuav tsub tsis tu ncua. Cov nyhuv no yog hu ua inductive thiab thaum kawg, nws yog coj raws li ib lub hauv paus rau zus tau tej cov network ntxaij lim dej. Raws li ib tug tshwm sim, nws yog muaj peev xwm mus tiv nrog loj thiab me me sinusoids sij hawm, uas ua rau high-zaus cuam. Rau qhov zoo tshaj plaws ua hauj lwm, siv ob coils. Lawv sib npaug coj lub load ntawm sinusoids. Ib kauj yog nyob rau hauv lub nruab nrab neeg xyuas pib, thiab lub thib ob - nyob rau hauv theem. Nyob rau hauv lub network lim qauv, lub inductance yuav txawv. Ib kauj muaj peev xwm sawv ntawm tiv 50 mus rau 200 uh.

Tsawg zaus cuam

Lwm qhov teeb meem yog suab nrov, uas muaj ib tug sab zaus. Rau lawv hluav coils kuj siv, tab sis muaj tus nquag kuj. Tsis tas li ntawd, network cov ntxaij lim dej yuav txawm peem rau nrog ob peb resistors, uas muaj peev xwm ua tau rau ib tug tseem ceeb load. Nco ntsoov, txawm li cas los, tias tus ciaj ciam ntawm lub resistors yuav tsum tsis txhob yuav nyob rau hauv ib theem siab. Qhov no yog vim lub voltage nco nyob rau hauv lub zuag qhia tag nrho system. Thaum lub resistor yuav muaj ib tug siab impedance, txoj kab voltage yuav poob ho. Nyob rau nruab nrab manufacturers tsim lawv nrog cov tsis ntawm 0.5 ohms. Qhov loj tshaj plaws uas tsis pub tshaj 1 ohm.

Lim APC P5BV-RS

Mains lim rau APC P5BV-RS computer yog tau tiv nrog impulses, uas muaj peev xwm muab tau los ntawm xob ntaus.
