Indlela kutsho ngekhompyutha? Amathiphu namacebo

indlu zesimanje igcwele khona ezihlukahlukene Amadivayisi kagesi nemishini. Amafriji, imishini yokuwasha, amathelevishini nezinye electronics uxhumeke kwi-amapayipi ngogesi, voltage okuyinto usongo ekuphileni komuntu. zikagesi, ukwehluleka imishini kungaholela yokubakhona imisinga ngebutho amancane voltage phezulu uma izinto zasendlini, okuyinto ngempela ezingemnandi, futhi ngezinye izikhathi yingozi kubantu. Indlela babegayela ikhompyutha nezinye electronics, futhi kungani kudingeka?

Kuyini isidingo kutsho zikagesi?

Okokuqala uhlelo emhlabeni kuyadingeka ukuze kuvikelwe ukuphila nempilo yabantu. Ngezinye izikhathi ngokuthinta, ikakhulukazi isandla ezimanzi bezinhlamvu metal imbala noma ukuwasha machine, ungaziqhenya imiphumela engasi mihle kagesi. Lokhu kusikisela ukwahlukanisa abampofu ekhaya Imishini izingxenye kanye wiring, futhi ukungabi khona isisekelo. Ngokuvamile kwenzeka emizini emidala, lapho wire phansi azange linikelwe. Thola inethiwekhi kagesi ngaphandle phansi wire ilula ngokwanele - izisekelo ayinayo phansi. Nakuba endabeni isimo reverse, lapho efakwe isisekelo uphuma khona, kodwa akukho wire phansi. Noma enethiwekhi ukukhwezwa ngaphandle emhlabeni, umane nje uhlezi ayixhunyiwe izintambo ezidingekayo.

Ngo indlu yangasese

Ukuklama futhi ukukhiqiza uhlelo ukufakwa earthing ezakhiweni ongaphakeme liphumele ngaphansi amandla ngamunye. Ngokuvamile kutsho kulokhu siqukethe isimiso mpo futhi enezingqimba earthing umqhubi nokuxhuma uhlelo iphaneli kagesi endlini. Izakhi mpo wangcwatshwa umhlaba futhi uxhumeke kwi-evundlile.

izakhi isisekelo Kuqondile zingenziwa 50-mm steel engela, futhi izakhi mpo efanelekayo abavamile steel emapheshana 40-50 mm. Njengoba umqhubi isisekelo angasebenzisa kuhlinzwa round. Ground iluphu Kunconywa ukwenza ngendlela unxantathu equilateral kude kusukela ekusekelweni ezingaphezu kuka-1 imitha. Painted izakhi steel akudingekile. Ngokulandelako, cabangela indlela kutsho i-computer efulethini.

Le ndlu

Uma indlu ifakwe yesimanje earthing uhlelo (TN-CS), wiring has a PE umqhubi, okuthiwa "zero zokuzivikela." Batfola kutsi ngabe ikhaya lakho libe wiring akunzima kangako. Kulokhu, i kagesi ezifanelekile energostoyaku iyokwakhiwa izintambo ezinhlanu. Esimweni esinjalo kumele kube wonke amaqanda PE zokuzivikela uxhumeke ibhasi ezivamile, ibhasi exhunywe kwi-bezinhlamvu ka ibhokisi elithi inkinobho.

Indlela babegayela ikhompyutha uma efanelekayo energostoyaku wire ikhebula? Lokhu kusho ukuthi ekhaya lakho ifakwe i ephelelwe yisikhathi TN-C uhlelo earthing. Kulokhu, bentambo phansi engekho. Inketho engcono kuleli cala - ukwenza uhlelo uqobo. Lena elula abahlala esitezi sokuqala. Uma ukhuphule nokunyamalala nzima futhi eziyinkinga, akukuhle ukuxhuma kwentambo ongachemile lutho. Kancane ukuxazulula le nkinga futhi isize ukubeka RCD kwentambo ngamunye ivela efulethini ibhodi wokusabalalisa.

Kanjani hhayi ukukwenza

Abanye "ochwepheshe" aphonse emhlabeni wire ku ibhethri, igesi namanzi amapayipi ukuthi ingabe akuvumelekile. Lokhu "uhlelo" akuyona kuphela eziyingozi amalungu omndeni nomakhelwane eduze, kodwa futhi abantu abahlala ezindlini ezingomakhelwane.

Indlela kutsho kukhompyutha yakho ukuze kungabi fonil umbhobho?

Kwakukhona imisindo uma usebenzisa umbhobho? Lokhu kunganeliseki kwavela ngemva umbuzo indlela babegayela iyunithi uhlelo lwekhompyutha ukubhekana nabo? Impendulo ulula: udinga ukuxhuma ikhompyutha esokhethini lusekelwe. Okuphakela amandla has izihlungi ekhethekile ucime kokuthikanyezwa, futhi nokuthungatha sivale lapho sisilela khona kanye nomhlaba. Ngaphezu kwalokho, umsindo umsebenzi umbhobho kuthonywa nezinye izimbangela. Le nkinga kwenzeka kaningi, naphezu eliphezulu imibhobho futhi izintambo audiointrefeysov. Iphethini okuholela kungaba imvamisa high noma imvamisa low.

nomthelela obalulekile ukubukeka has high umsindo ongemuva yokuxhuma umbhobho Passive kukhompyutha ngokusebenzisa ikhadi umsindo noma esibonakalayo ekhethekile umsindo. Uma ikhebula kuyinto unshielded, eluka noma ilimele, buthule bese ukubaleka. Ngo isimiso esinjalo akukho preamplifier izimpawu kwaphazamiseka ngesikhathi samanje imvamisa ku amapayipi. Lahla lolu hlobo ngemuva, ungasebenzisa ikhebula eliphezulu.

Ngaphezu ikhwalithi embi noma izintambo ezilimele, nezixhumi sikhubazekile yokuxhuma imishini, ukubukeka ngemuva kungathinta ezinye izizathu. Futhi akusiwona microphone, futhi khona eduze nezinye izinto zikagesi, omakhalekhukhwini, ekhaya Imishini. Njengoba bevela isizinda sabo bangaba nethonya ngisho ezibizayo ikhebula kwakuvikela. Ezinye umsindo kungenzeka ngokuqhubekayo, ngezikhathi futhi abanye, ngesikhathi ukusebenza kwendlela yokwenza kagesi.
