Ngaba uke wazibuza ukuba imali engakanani umthengi uchitha kwiimpahla zendlu? Izindlu zethu kunye neendawo zokuhlala zizaliswe ngeefowuni ezahlukeneyo ukusuka kumxube oqhelekileyo kwiibhodi ezinkulu. Ukuba nazo zonke ezi zixhobo, kungekudala okanye kamva kufika umzuzu wokuthenga ukuzinzisa. Inyaniso kukuba, njengendawo yokuhlala yedolophu, kunye ne-dacha, akusoloko ikhona i-voltage surges. Ngoko ke, kucetyiswa ukuba utyalomali kwi-voltage regulator ye-220 V, kwaye kufuneka kukhethwe bani, siya kuqwalasela ngezantsi.
Unokukhetha njani umlawuli wee-voltage?
Kwimeko yezindlu zelizwe, ingakumbi iidaka, kufuneka ufake isilondolozi malunga nento yokuqala. Uninzi lwezindlu zakudala zenzelwe ukusetyenziswa okungaphantsi kwamandla kwaye ngenxa yoko, umnatha unakho kuphela ii-volts ezingama-130 endaweni efunekayo 220.
Ukuhlala kwehlobo kukho izinto ezintathu ezibalulekileyo kumbuzo wokukhetha indlela yokulawula umbane:
- Kubalulekile ukubala ukusetyenziswa kwamandla onke. Emva koko, sikhetha i-apparatus ngamandla amakhulu kunani elifumene emva kokungezelela. Ukuze ukhethe ngokufanelekileyo umlawuli wombane, qwalasela ubugcisa kunye neepompo, njengoko kukhulisa ngokukhawuleza izinga lokusetyenziswa kwamandla. Ukwenza oku, ukwahlula ixabiso elifunyenwe ngu-0.7.
- Emva koko, sibala inani elincinci lokusetyenziswa kwamandla. Nanku kwanele ukuba sisebenzise izibungu zokuqokelela zamanje. Kwidivaysi ekhethiweyo, umda osezantsi kufuneka ube ngaphantsi.
- Khumbula kwakhona inani lezigaba endlwini. Ukuba uthe wedwa, akuyi kuba neengxaki. Xa kukho ezintathu, kuya kufuneka ukhethe phakathi kokuthenga isithathu-sigaba esinye okanye esinye sigaba sesithathu.
Nguwuphi umlawuli wezithuthi ozikhethele indlu?
Ngaphambi kokuthenga idivaysi yendlu, kufuneka uphendule imibuzo emibili kuphela. Iyiphi inani leemitha zokuvutha eziqhelekileyo endlwini? Ukuba ezi zihambayo zingaphakathi kwemida ye-210-230 W, kuya kubakho ubunele uhlobo oluthile lwenkqubo ethile. Xa umda ophezulu usuvele u-260 W, kukufanelekile ukucinga malunga nokuchaneka okuphezulu kunye nolungiso olulungelelanisiweyo.
Emva koko, kufuneka uthathe isigqibo sokuba yeyiphi umlawuli wezithuthi ozikhethileyo kwiindawo zokugcina izakhiwo kwindlu:
- I-Servo drive iyona ephantsi kakhulu, kodwa inamacandelo amaninzi amaninzi, kukho ukuphakama okuphezulu kokuphazamiseka okusisigxina;
- kunokwenzeka ukuba ukhethe umlawuli wombane wohlobo oludlulileyo , luya kuba lufanelekile kokubili ekhaya kunye nefesti (oku kuluhlu lwamaxabiso ephakathi, kodwa luya kuhlala ludlulanga ngaphezu kweminyaka emibini);
- I-thyristor imodeli yecomputer ye- voltage regulator ngokuvamile ikhuthazwa ukukhetha indlu yangasese: nokuba nayiphi i-voltage ixuma, iphendula ngokukhawuleza.
