Chinoputsa Dunhu Chinosara: Guarantii Yemagetsi Akachengeteka

KunzwisisaMaResidual Circuit Breakers: Gwaro Rakazara

Munyaya dzekuchengetedzwa kwemagetsi, maResidual current circuit breakers (RCBs) anoita basa guru mukudzivirira vanhu nepfuma kubva kumatambudziko emagetsi. Mudziyo uyu wakagadzirwa kuti uone kusawirirana kwemagetsi uye kuvhura circuit kana paine chikanganiso, nokudaro kudzivirira njodzi dzingangoitika dzakadai sekuvhunduka kwemagetsi nemoto. Munyaya ino, tichanyatsoongorora mashandiro anoita maEarth leakage circuit breakers, zvakanakira zvawo, uye mashandisirwo awo.

Chii chinonzi leakage circuit breaker?

Chinopwanya magetsi chinosara, chinowanzonzi mudziyo wemagetsi unosara (RCD) kana kuti chinopwanya magetsi chinosara (RCCB), chishandiso chemagetsi chinotarisa magetsi ari mudunhu remagetsi. Chinogara chichienzanisa magetsi ari kufamba nepakati pewaya dzinoshanda nedzisina simba. Kazhinji, magetsi ari muwaya dzese mbiri anofanira kunge akaenzana. Zvisinei, kana paine dambudziko, senge short circuit kana mumwe munhu akabata waya inoshanda, magetsi anogona kusashanda zvakanaka. RCB inoona kusashanda zvakanaka uku uye inovhura dunhu nekukurumidza, kazhinji mukati memamirisekonzi mashoma.

Muchina wekupwanya dunhu unobuda unoshanda sei?

Kushanda kwema earth leakage circuit breakers kwakavakirwa papfungwa ye electromagnetic induction. Mudziyo uyu une iron core ine ma coil maviri: rimwe re live wire uye rimwe re neutral wire. Kana ma currents akaenzana, ma magnetic fields anogadzirwa nema coils aya anodzimana. Zvisinei, kana leakage current iripo (zvichiratidza kuti pane zvikanganiso), ma magnetic fields haazodzima, zvichikonzera differential current triggering mechanism kuti iparadze circuit.

MaRCB mazhinji akagadzirwa kuti akwanise kudonha pamagetsi anobuda, anowanzo bva pa30 mA yekudzivirira munhu kusvika pa100 mA kana kupfuura yekudzivirira michina. Kunzwa uku kunoita kuti kunyangwe madonhwe madiki anogona kukonzera njodzi yekuvhunduka kwemagetsi aonekwe nekukasika uye agadziriswe.

Mabhenefiti ekushandisa earth leakage circuit breaker

1. Kuchengetedzwa Kwakawedzerwa: Chinhu chikuru chinobatsira RCB kuchengetedza kwakawedzerwa kwainopa. Nekubvisa circuit kana paine chikanganiso, njodzi yekubatidzwa nemagetsi uye moto wemagetsi inogona kuderedzwa zvakanyanya.

2. Kudzivirirwa kweMidziyo: Pamusoro pekuchengetedza hupenyu hwevanhu, RCB inogonawo kuchengetedza midziyo yemagetsi nemidziyo kubva mukukuvadzwa kunokonzerwa nekutadza kwemagetsi.

3. KUTEVEDZERA MITEMO YEMAKODHI: Makodhi mazhinji ekuchengetedza emagetsi nemakodhi ekuvaka anoda kuti pave nemaresidual circuit breakers mudzimba dzekugara nedzemabhizinesi. Kushandiswa kweRCB kunovimbisa kutevedzera mitemo iyi.

4. Rugare Rwepfungwa: Kuziva kuti pane chinhu chinobvisa mvura mumhepo chinogona kupa varidzi vedzimba nevaridzi vemabhizinesi rugare rwepfungwa, zvichivabvumira kushandisa michina yemagetsi vasinganetseki nezvenjodzi dzingangoitika.

Kushandiswa kwe earth leakage circuit breaker

Zvidziviriro zvemagetsi zvinopwanya mvura pasi pevhu zvinoshandiswa zvakanyanya mumamiriro akasiyana-siyana, kusanganisira:

- KUVAKA KWEMAHARA: MaRCB anowanzoiswa mudzimba kudzivirira kurohwa nemagetsi, kunyanya munzvimbo dzine mvura dzakadai sedzimba dzekugezera nemakicheni.

- Dzimba dzeMabhizinesi: Mabhizinesi anoshandisa RCB kuona kuchengetedzeka kwevashandi nevatengi, uye kuchengetedza michina inobatwa nenjodzi.

- Nzvimbo dzeMaindasitiri: Mumafekitori nenzvimbo dzemaindasitiri, maRCB akakosha kuchengetedza michina uye kuona kuchengetedzeka kwevashandi munzvimbo dzine njodzi huru.

Muchidimbu

Muchidimbu, ma "earth leakage circuit breakers" chikamu chakakosha chemagetsi emazuva ano, zvichipa dziviriro yakakosha kubva kumatambudziko emagetsi. Kukwanisa kwayo kuona kusawirirana kuripo uye kubvisa ma "circuit" nekukurumidza kunoita kuti ive mudziyo unokosha wekuchengetedza mudzimba, mabhizinesi nenzvimbo dzemaindasitiri. Nekunzwisisa kukosha uye mabasa ema "earth leakage circuit breakers", vanhu nemasangano vanogona kutora matanho ekuvandudza kuchengetedzeka kwemagetsi uye kutevedzera mitemo. Kudyara mari muRCB hakusi kungotevedzera mitemo chete; kuzvipira kukuchengetedza nekugara zvakanaka munyika yedu iri kuwedzera kushandiswa kwemagetsi.
