Ese Surge Protector izakora nta butaka?

Nigeze kureba serveur ikaranze $3,000 mu biro byanjye kuko "agace k'isukari" nta butaka nyakuri kari gafite. Uwo mwotsi uracyantungura amaso.

Oya, icyuma kirinda umuyaga ntigishobora kurinda ibikoresho byawe niba aho urukuta rudafite insinga nyayo y'ubutaka; gishobora gutanga ingufu, ariko ingufu zangiza umuyaga ntaho zigarukira.

Komeza usome nzakwereka impamvu nyayo pin ibura atari akantu gato, uburyo ngerageza amasoko mu masegonda mirongo itatu, n'icyo nkora iyo inyubako ishaje idafite aho ihuriye na gato.

Umurinzi wo kuzamuka akora ate?

Ndacyibuka urusaku rw'inkuba ubwo inkuba yakubitaga igisenge cy'umuturanyi wacu. Igitekerezo cyanjye cya mbere cyari iki: “Ndakwinginze ureke MOV iri mu gice cyanjye ibyine.”

Imashini irinda ingufu ziyongera ku mugozi wo hasi ikoresheje Metal-Oxide Varistor; iyo nta nzira yo gusohokamo, ingufu ziguma mu muyoboro wawe kandi zigatwika chip idakomeye cyane.

Igice gito cyane gifata isasu

Muri buri gice uzasangamo MOV imwe cyangwa nyinshi. Ziba hagati y’ibiriho n’ibiri hasi, zidafite aho zibogamiye n’ibiri hasi. Kuri 130 V zirafata, ariko fata ikora gusa iyo ubutaka butegereje nk’umuyoboro ufunguye.

Agace gashobora gutwara UL 1449 ariko kagakomeza kukunanira. Nafunguye utubari twanditseho "CE" tudafite agapira ko hasi kuri plug. MOV yashyizwe kuri pin y'impimbano ya pulasitiki. Ingufu ihita ibona inzira ikurikiraho nziza—akenshi inyura kuri waya ya Ethernet ikajya muri motherboard ya mudasobwa yawe.

Ikizamini cyanjye cy'iminota ibiri cyo gupima soketi

Mbere yo gushyiramo ikintu gihenze, nkoresha ikizamini cya $3. Amatara atatu agomba kwaka. Iyo iri hagati ryijimye, mpamagara umuhanga mu by'amashanyarazi cyangwa nkamura agakoresho ko ku gitereko. Sinigeze nizera ijambo ry'umuntu ufite inzu uvuga ati “Birashoboka ko ari byiza.”

Bigenda bite iyo MOV ipfuye

MOV ntizikira. Nyuma yo gukubitwa cyane, voltage yazo irazamuka. Umunsi umwe, ingufu ziba nyinshi kurusha MOV inaniwe, maze ingufu zigatangira kwinjira mu muyoboro w'amashanyarazi. Nhinduranya imirongo buri myaka itatu mu gihugu cy'imirasire, buri myaka itanu ahandi.

Ese ibikoresho byose bikingira indwara y'ubwiyongere bw'umubiri bifite ishingiro?

Namenye mu buryo bugoye ko ikimenyetso cya "surge" kiri ku gasanduku kidasobanura ko agace gafite agapira ko hasi; bamwe barinda gusa imirongo y'amakuru kandi bagasiga inzira y'amashanyarazi yambaye ubusa.

Oya, ibikoresho byinshi bikingira amaguru bingana n'ingendo n'ibice bibiri nta miyoboro bifite ku butaka; byishingikiriza ku gufunga umurongo kandi bigatanga uburinzi bw'igice gusa.

Amayeri yo kwamamaza yanteye ishozi

Umwaka ushize naguze agace keza k'umweru kugira ngo nfotore. Agace kari gafite udupira tubiri gusa. Inyuguti nto zanditseho ngo "uburinzi bw'umuraba hagati y'imirongo." Ibyo bifasha mu kwirinda uduce duto, ariko inkuba izakomeza gusunika 6 kV kuri chassis.

Ameza yo gufunga afite udupira tubiri

Impamvu nkikoresha utubari tw'udupira tubiri

Ndazikoresha, ariko gusa ku matara no mu gushyushya terefone. Ndazishyiraho izina ngo “NTIBIGIZE IGIKORESHO GIKORESHWA—NTIBIGIZE IGIHENDA” kugira ngo abanyeshuri banjye batongere kuzishyiraho oscilloscope.

Agace k'imvi: Isoko rya GFCI

Amwe mu ma laboratwari ashaje afite aho GFCI ikorera nta mwanya wo hasi. GFCI izagufasha kurokora ubuzima bwawe, ariko ituma imbaraga ziyongera ntaho zijya. Nongeraho module ya MOV iri ku murongo ifatanye n'umuyoboro w'amazi iyo ngeze kuri iyi gahunda.

Ingaruka n'ibibazo by'umutekano byo gukoresha Surge Protectors Ungrounded

Nari mfite impumuro ya pulasitiki isha saa mbiri za mu gitondo muri hoteli; aho hantu nta butaka hari hafite maze umuvuduko unyura mu mugozi wa USB-C, ushyira mudasobwa yanjye igendanwa ku meza.

Iyo hatabayeho ubutaka, ingufu zituruka ku butaka zishobora kwinjira mu gice cy’ubutaka, zigatwika pulasitiki, cyangwa zigaca mu nsinga z’umuyoboro w’itumanaho maze zigasenya igikoresho cyose gihujwe.

Umuriro uratangira imbere muri pulasitiki
