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

Ib tug ntawm cov txheej xwm rau lub lag luam ntawm hluav taws xob yog ib tug ruaj khov fais fab mov. Lub voltage hloov nyob rau hauv lub mov network yuav critically cuam tshuam lub lag luam ntawm ib tug neeg hauv tsev neeg kws. Semiconductor Cheebtsam muab sij hawm ntxiv rau txoj kev loj hlob ntawm ntau yam pab kiag li lawm. Tu siab, lawv yog nkag rau kev khiav hauj lwm tej yam kev mob thiab xav tau ceev faj kev kho mob. Ib tug ntawm cov pab kiag li lawm uas tej zaum yuav tiv thaiv cov electronics ntawm kev puas tsuaj vim rau lub hwj chim surges los yog theem ntawm impulse suab nrov nyob rau hauv lub mov network, yog ib tug network lim. Nws copes nrog nws ua hauj lwm thiab prolongs lub neej ntawm lub twj paj nruag.

Wb pom lub hwj huam mov thiab saib yuav ua li cas sib txawv ntawm cov kev pab muaj feem xyuam rau nws qhov chaw. Thiab raws li ib tug network lim tej yam hauv lub tshuab hluav taws xob ntaus ntawv los ntawm kev puas tsuaj? Qhov tseeb tiag mas, cov mov voltage yog ib tug sinusoid. Nws yog ib txwm nyob rau hauv nws tam sim no (amplitude) thiab zaus. Tu siab, thaum cov haib tau txais kev pab ntawm hluav taws xob muaj ntau hom cuam, uas yuav ua kev puas rhiab khoom.

Nyob rau hauv lub neej txhua hnub xws "nrov" hluav taws xob khoom siv xws li lub tshuab nqus tsev, tub yees los yog huab cua txias. Qhov ntawd yog qhov chaw uas cov ua hauj lwm los yog lwm yam hom asynchronous motors, kom paub tseeb tias cov distortions nyob rau hauv lub mov network. Qhov no yog vim sparking nyob rau hauv lub txhuam hniav los yog rau lwm yam yog vim li cas. Txawm zoo tib yam lag luam los ntawm cov hluav taws xob shaver peev xwm cuam tshuam, piv txwv li, cov xov tooj cua receivers. Nyob rau hauv lwm yam lus, muab nrog ib tug inductive load thiab luv so qho hluav taws xob Circuit Court (raws li yog cov ntaub ntawv nyob rau hauv lub cev muaj zog txhuam) cuam lub caij nplooj zeeg nyob rau hauv lub mains mov. Lawv yog cov luv luv overvoltage pulses. Surge protector, nruj me ntsis hais lus, teem kam nrog xws li anomalies.

Tab sis qhov teeb meem tsis yog tsuas yog nyob rau hauv hluav taws xob motors. Txawm tib hom kab ntau ntau "ua pa nrov" pab kiag li lawm yog lawv tus kheej niaj hnub electronics: televisions, stereos, computers, thiab lwm yam Nws hloov tawm hais tias lub surge protector yog tau los tiv thaiv lub electronics ntawm kev puas tsuaj, uas yog nws tus kheej tseem tsim unfavorable tej yam kev mob rau lawv cov ua hauj lwm. Qhov tseeb hais tias niaj hnub pab kiag li lawm yog muaj li ntawm switching khoom siv fais fab, uas nws ua hauj lwm yog hais txog mus rau lub zaus ntawm 1000 Hz los yog ntau tshaj. Txij li thaum nyob rau kev nkag ntawm tej pab kiag li lawm yog transformers muaj ib tug tej yam inductance, ces cuam tshwm sim.

Lawv yog cov yooj yim mus saib nrog ib tug oscilloscope. Koj muaj peev xwm sau ib tug me me surge protector nrog koj ob txhais tes los xyuas kom meej cov hauj lwm zoo ntawm nws daim ntawv thov. Nws yog txaus los ua ib tug inductance, uas yuav tiv thaiv tau cov zaj uas lub high-zaus suab nrov nyob rau hauv lub mains mov. Rau lub hom phiaj no tsuas qhwv ib yam naj npawb ntawm cov lem ntawm hlau, piv txwv li, cov qhab nia nyob rau Xaws ferrite nplhaib thiab solder nws successively mus rau lub pub Circuit Court rau lub computer. Nrog ib qho kev nce nyob rau hauv lub inductance (tus naj npawb ntawm lem) koj yuav pom nyob rau hauv lub oscilloscope uas cuam yuav maj mam ploj.

Tam sim no, muaj ib tug loj tus naj npawb ntawm network cov ntxaij lim dej uas yeej tsim los ua hauj lwm nrog ntau hom ntawm load. Ib tug piv txwv zoo nyob rau hauv cov ntaub ntawv no tej zaum yuav ua tau ib tug kab lim tsav, uas muaj zoo heev ua tau zoo.
