Fizikisi y’amasannyalaze eya brownouts: Lwaki vvulovumenti entono eyokya mmotoka¶

Bannannyini mayumba bangi mu ngeri ey’okutegeera balowooza nti vvulovumenti eya waggulu (nga okumyansa kw’omulabe) y’esiika ebyuma by’amasannyalaze, era nti vvulovumenti entono (a brownout) emala kuleetera ebyuma okutambula mpola katono oba okunyogoga. Mu butuufu, wadde nga obuuma obuyitibwa electronic circuit boards buba mu bulabe bw’okusindika kwa vvulovumenti ennene, mota z’amasannyalaze eziyitibwa inductive electric motors zisaanawo emirundi mingi nnyo olw’obuziba obutono obuwangaala.

1. Emigugu egy’amaanyi agatali gakyukakyuka n’omutego gwa amperage \(P = V \times I\)¶

Ebyuma by’omu nnyumba bigwa mu biti bisatu eby’enjawulo eby’emigugu gy’amasannyalaze ebikola mu ngeri ezitali zimu ddala nga vvulovumenti y’amasannyalaze ekendedde ebitundu 15 ku 25 ku buli 100 mu kiseera ky’embeera ey’amangu ku ggirita:

• Emigugu gy’ebbugumu eriziyiza (Toasters, ovens z’amasannyalaze, baseboard heaters, incandescent bulbs): Efugibwa etteeka lya Ohm (\(I = V / R\)). Voltage ya grid bw’ekka ebitundu 20 ku buli 100 (okuva ku volts 120 okutuuka ku volts 96, oba okuva ku volts 230 wansi okutuuka ku volts 184), current ekulukuta mu nichrome heating element nayo ekendeera ebitundu 20 ku buli 100, ate ebbugumu erifuluma ne likendeera ebitundu 36 ku buli 100. Resistive heaters zitambula nga zibuguma mu kiseera kya brownout era tezonoonebwa olw’obuziba obutono.
• Mota za AC induction eza phase emu ne phase ssatu (Frigerator compressors, central AC condensers, heat pumps, well pumps, sump pumps, washing machines): Motoka ya induction evuga compressor ey’ebyuma ye constant-torque load. Okunyigiriza ggaasi wa firiigi ku puleesa ya kondensa ey’oludda olwa waggulu etakyukakyuka, mmotoka yeetaaga omuwendo ogutakyuka ogwa wattage ey’ebyuma (\(P = V \times I \times \text{Power Factor}\)). Voltage ya utility grid (\(V\)) bw’ekendeera ebitundu 20 ku buli 100, motor eseerera mu sipiidi y’okuzimbulukuka era esika amasannyalaze agasingako ebitundu 25 ku 40 ku buli 100 (\(I\), amperage) okutuusa torque y’ebyuma y’emu.
• Okubuguma kwa joule mu biwujjo bya mmotoka (\(Q = I^2 \times R \times t\)): Ebbugumu erikolebwa munda mu waya ya magineeti y’ekikomo eya kompyuta compressor ligeraageranye ne square ya current (\(I^2R\)) ate nga ffaani y’okunyogoza ey’omunda eya motor yeekulukuunya mpola. Okukendeera kwa vvulovumenti ya utility ebitundu 20 ku 100 kuyinza okwongera ku bbugumu ly’ekikomo eky’omunda mu kuzingulula 35 ku 60 degrees Celsius (63 ku 108 degrees Fahrenheit) mu ddakiika ntono, okufumba insulation ya varnish okutuusa ekikomo ekiriraanyewo lwe kikyusizza short-circuit wamu.

2. Locked Rotor Amps (LRA) ne "Short-Cycling" emidaala gya puleesa y'omutwe¶

Ekitta kya kompyuta ekisingako amangu kibaawo ng’amasannyalaze ga giridi gaaka okumala wakati wa sikonda 0.5 ne sikonda 60 nga firiigi yo oba ekyuma ekifuuwa empewo kikola:

1. Nga kompyuta ekola bulungi, epampagira firiigi mu koyilo za kondensa ez’oludda olwa waggulu ku puleesa eya waggulu (1,700 ku 2,800 kilopascals / 250 ku 400 psi), ate layini y’okusonseka ku ludda olwa wansi etuula ku puleesa entono (400 ku 700 kilopascals / 60 ku 100 psi).
2. Amasannyalaze bwe gasalako okumala sekondi 3 ne gaddamu okukuba amangu ago, oba vvulovumenti ya giridi bwe yakendeera okutuuka ku vvulovumenti 85, ekisenge ekyo ekya puleesa ekya kilopascal 2,000 (300 psi) kiba kitudde waggulu ddala ku pisitoni ya kompyuta oba omuzingo.
3. Ffiriigi ya phase emu ne mmotoka za HVAC tezirina torque etandikira emala okutandika okuwuuta ku puleesa y’omutwe enkulu nga vvulovumenti ya layini ekendedde. Mu nkola eya bulijjo, kompyuta yeetaaga eddakiika 3 ku 5 nga tezikola puleesa za firiigi okwenkanankana okubuna ttanka y’emisuwa oba vvaalu y’okugaziya nga tennaddamu kutandika.
4. N’olwekyo, ekiwujjo kya mmotoka kisiba nga kifudde (Embeera ya Rotor ekwatiddwa). Mu kifo ky’okukuba Running Load Amps (RLA) yaayo eya bulijjo (amps 1.5 ku firiigi oba amps 15 ku AC eya wakati), rotor esimbye ekuba Locked Rotor Amps (LRA): Amps 10 ku 15 ku firiigi ne amps 60 ku 110 ku ekyuma ekifuuwa empewo ekiri wakati.
5. Compressor etuula awo ng’ewuuma nnyo, ng’efumba ebiwujjo byayo okutuusa ng’omugugu gw’ebbugumu gunyiga ne gugguka, ne gunyogoga okumala sekondi 90, n’egezaako okutandika mu brownout enfunda n’enfunda okutuusa nga capacitor y’okutandika ekutuse oba compressor lw’ekwata enkalakkalira.

3. Lwaki Switch-Mode Power Supplies (SMPS) mu byuma eby’omulembe nazo zirema mu brownouts¶

Oyinza okwebuuza lwaki kompyuta ez'omulembe, ttivvi za OLED, Wi-Fi routers, ne "smart" inverter refrigerator mainboards nabyo byokya mu biseera bya low-voltage brownouts bwe biba nga tebirina induction motor nnene. Ebyuma eby’omulembe bikozesa Universal Switch-Mode Power Supplies (SMPS) ezipimiddwa ku 100 ku 240 volts AC. Olw’okuba SMPS kikyusa amaanyi agatali gakyukakyuka, nga vvulovumenti y’ekisenge kya AC eyingizibwa ekka wansi ng’eyolekera vvulovumenti 80 oba 90, ekyuma ekitereeza omutala oguyingira ne transistors ezikyusa MOSFET eza vvulovumenti enkulu zirina okusigala nga zikoleezeddwa okumala ekiseera ekiwanvu ennyo era okusika emirundi ebiri amperage eyingizibwa okukuuma eggaali z’omukka eza kompyuta eza DC eza vvulovumenti 12 ne vvulovumenti 5 nga tezikyukakyuka. Singa vvulovumenti ya giridi ewuuba ddala ku musingi gw’okuggala vvulovumenti eya wansi wa converter (around 75 to 88 volts AC), amasannyalaze gawuuma mangu nga gaaka n’okuzikira emirundi amakumi buli sikonda, ne gafuuwa primary switching MOSFET ne input varistor.

   • Nga wabulayo essaawa 2 eddirisa livuddeko: Teeka thermostat yo diguli 2 ku 3 (diguli 4 ku 6 Fahrenheit) okusinga bulijjo okusobola okusooka okunyogoza drywall n’ebintu by’omu nnyumba mu maka go, olwo oggale AC OFF ng’ebula eddakiika 10 okutuuka waggulu w’essaawa olwo compressor ebeere nga tekola nga breaker egguddwawo.
   • Jjuza ekifo ekyerere mu firiiza yo ne firiigi n’amacupa g’amazzi: Ebibbo by’obuveera ebitundu bisatu ku bina ebijjudde amazzi ga ttaapu agafumbiddwa bikola nga bbaatule ez’ebbugumu ezikubisaamu emirundi ebiri obudde bw’okukwata firiiza ne firiigi yo mu nnyonta.
   • Weewale lifuti ng’ebula eddakiika 15 okutuuka waggulu ne wansi buli ssaawa: Okuyiwa emigugu gy’ebikozesebwa kubaawo okumpi n’okungulu (:00) oba wansi (:30) y’essaawa. Tolinnyangako mu lifuti mu biseera by’okulabula kwa brownout okukola; laba ebyaffe embeera ez’amangu eza lifuti guide singa oba asibiddwa.

Okugonjoola ebizibu eby’amangu: Singa ekyuma tekijja kuddamu kutandika oluvannyuma lw’okuggwaamu¶

Singa amaanyi ga utility gateredde ku 120 volts (oba 230 volts) era compressor egaana okutandika oba efuuwa empewo eyokya, kola kino Thermal Overload Reset Check:

1. Ekikuuma ebbugumu munda mu ddakiika 45 Cool-Down¶

Buli kompyuta ya firiigi, firiiza y’ekifuba, ne kondensa ya AC ey’omu makkati birimu bi-metallic thermal overload protector ekissiddwa ku kisusunku kya kompyuta eky’ekyuma. - Singa compressor egezaako okutandika mu kiseera ky’okufuuka brownout n’egwa ku Locked Rotor Amps, compressor dome ey’omunda esobola okutuuka ku 105 ku 130 degrees Celsius (221 ku 266 degrees Fahrenheit) era n’eyiwa ebbugumu mpola munda mu vacuum shell. Ne bwe kiba nti amaanyi ga giridi gazzeeyo, switch y’ebbugumu erisukkiridde esigala nga nzigule okutuusa ng’ebiwujjo bya mmotoka binyogoze wansi wa diguli 65 (diguli 150 eza Fahrenheit). - The Fix: Ggyako firiigi oba kyusa AC condenser breaker OFF okumala eddakiika 45 ku 60 (nga okuuma enzigi nga nzigale) olwo thermal overload elekera awo okuvuga obugaali era compressor dome enyogoze ddala. Oluvannyuma lw’eddakiika 60, ddamu okugiyunga; emirundi egisinga, kompyuta ennyogovu ejja kutandika okutuukira ddala waggulu.

2. Okuzzaawo emikutu gya GFCI / AFCI n’okukebera capacitor ya HVAC ey’ebweru¶

• Kebera emikutu gya GFCI egy’okungulu n’ebimenya AFCI: Ensigo z’okuzzaawo zitera okugwa Ground Fault Circuit Interrupter (GFCI) ebifo ebikuumirwamu mu galagi, mu bisenge ebya wansi, n’amafumbiro, oba ebimenya Arc Fault (AFCI). Press RESET firmly ku GFCI outlet yonna, era flip tripped circuit breakers okutuukira ddala ku OFF n'okudda ku ON.
• Kebera oba HVAC Dual-Run Capacitor efuukuuse: Singa ffaani yo eya blower ey’omunda ekola bulungi, condenser yo ey’ebweru n’ewuuma, ate ennyumba n’efuuwa empewo ebuguma oluvannyuma lw’okufuuka brownout, omusango ogusinga okubeera aluminum Dual-Run Start/Run Capacitor efuuwa munda mu condenser panel ey’ebweru. Brownouts eza voltage entono zibugumya nnyo woyiro wa dielectric munda mu capacitors ezidduka mu aluminiyamu eziriko cylindrical, ekivaako waggulu w’ekibbo ky’ekyuma okubumbulukuka waggulu nga ekibbo kya sooda ekifuuse bbugumu, ne kibuuka ekiziyiza puleesa yaakyo ey’omunda. Omukugu mu by’okukola HVAC alina layisinsi asobola okukyusa capacitor efuumuuka (bulged run capacitor) mu ddakiika 15.
