Ho Utloisisa RCCB: Sesepa sa Potoloho sa Hona Joale se sa Lefelloeng
Lefatšeng la polokeho ea motlakase, li-residual current circuit breaker (RCCBs) li bapala karolo ea bohlokoa ho sireletseng batho le thepa likotsing tsa motlakase. Lisebelisoa tsena li etselitsoe ho thibela ho tšoha ha motlakase le ho fokotsa kotsi ea mollo oa motlakase o bakoang ke liphoso tsa mobu. Sengoloa sena se tla shebisisa haholoanyane mosebetsi, bohlokoa le ts'ebeliso ea li-RCCB.
RCCB ke eng?
RCCB (Residual Current Circuit Breaker) ke sesebelisoa sa motlakase se kgaolang potoloho ha se lemoha ho se leka-lekane pakeng tsa lithapo tse phelang (phase) le tse sa nke lehlakore. Ho se leka-lekane hona ho bontša hore motlakase o dutla lefatšeng, e leng se ka bakoang ke terata e fosahetseng, ho senyeha ha insulation, kapa ho kopana ka phoso le likarolo tse phelang. RCCB e lula e lekola motlakase o phallang potolohong mme e ka arabela maemong afe kapa afe a sa tloaelehang ka har'a li-millisecond ho netefatsa polokeho.
RCCB e sebetsa joang?
RCCB e sebetsa ka ho lekanya motlakase o phallang ka hara lithapo tse chesang le tse sa nke lehlakore. Ka tlwaelo, motlakase o kenang ka hara potoloho ka hara terata e chesang o lokela ho lekana le motlakase o kgutlang ka terata e sa nke lehlakore. Haeba ho na le phapang, RCCB e lemoha ho se leka-lekane hona.
Ha RCCB e utlwa phallo ya motlakase e dutlang, e qala mokgwa o bulang potoloho, ka hona e thibela ho tshoha ha motlakase kapa mollo. Di-RCCB di fapana ka kutlwisiso, mme ditekanyetso tse tlwaelehileng tsa phallo ya motlakase ke 30mA (bakeng sa tshireletso ya motho ka mong) le 100mA kapa 300mA (bakeng sa tshireletso ya mollo).
Bohlokoa ba RCCB
Bohlokoa ba li-RCCB bo ke ke ba feteletsoa. Ke mothapo oa bohlokoa oa tšireletso khahlanong le likotsi tsa motlakase. Mona ke a mang a mabaka a bohlokoa a hore na ke hobane'ng ha li-RCCB li le bohlokoa:
1. Tšireletso khahlanong le ho tšoha ha motlakase: Li-RCCB li etselitsoe ho sireletsa basebetsi ka ho khaola potoloho ha phoso e fumanoa. Sena se bohlokoa haholo libakeng tseo basebetsi ba ka 'nang ba kopana le likarolo tse phelang.
2. Thibelo ea Mollo: Liphoso tsa motlakase li ka baka ho chesa haholo le ho tuka. Li-RCCB li thusa ho thibela mollo oa motlakase le ho sireletsa thepa le bophelo ka ho lemoha maqhubu a ho lutla a ka bakang ho chesa haholo.
3. Latela maemo a motlakase: Linaha tse ngata li hloka ho kenngoa ha li-residual current circuit breaker (RCCBs) mehahong ea bolulo le ea khoebo. Ho latela maemo ana ha ho ntlafatse polokeho feela empa hape ho netefatsa hore ho kenngoa ha motlakase ho fihlela litlhoko tsa molao.
4. Khotso ea Kelello: Ho kenya sesebelisoa sa ho qhaqha potoloho ea motlakase se setseng (RCCB) ho fa beng ba matlo le beng ba likhoebo khotso ea kelello. Ba ka sebelisa lisebelisoa tsa bona tsa motlakase ntle le ho tšoenyeha ka likotsi tse ka bang teng.
Tšebeliso ea RCCB
Li-RCCB li na le mefuta e fapaneng ea tšebeliso, ho kenyeletsoa:
- Mehaho ea Bolulo: Malapeng, li-RCCB hangata li kenngoa botong e kholo ea kabo ho sireletsa lipotoloho tse fanang ka motlakase ho li-socket, mabone le lisebelisoa.
- Meaho ea Khoebo: Likhoebo hangata li sebelisa li-RCCB ho sireletsa lisebelisoa le ho netefatsa polokeho ea basebetsi le bareki.
- Litlhophiso tsa Liindasteri: Libakeng tsa indasteri, li-RCCB lia hlokahala ho sireletsa mechine le basebetsi liphosong tsa motlakase.
- Ho kenya kantle: Li-RCCB li boetse li sebelisoa lits'ebetsong tsa motlakase tsa kantle tse kang mabone a serapeng le matamo a ho sesa moo kotsi ea ho thothomela ha motlakase e leng holimo.
Ka bokhutšoane
Li-residual current circuit breaker (RCCBs) ke karolo ea bohlokoa ea litsamaiso tsa motlakase tsa sejoale-joale. Li khona ho lemoha le ho arabela ho se leka-lekane ha motlakase, ke lisebelisoa tsa bohlokoa tsa polokeho tse sireletsang bophelo le thepa likotsing tsa ho tšoha ha motlakase le mollo. Ha theknoloji e ntse e tsoela pele le litsamaiso tsa motlakase li ntse li rarahana haholoanyane, li-RCCB li tla tsoela pele ho bapala karolo ea bohlokoa ho netefatseng polokeho ea motlakase malapeng, libakeng tsa mosebetsi le libakeng tsa sechaba. Ho tsetela ho li-RCCB tsa boleng bo holimo le ho netefatsa hore li kentsoe le ho hlokomeloa hantle ke mohato oa bohlokoa ho ea tikolohong e sireletsehileng ea motlakase.
