Q: Lithium Esaanira Ebisale Ebisingako Mu Upfront Ku Telecom Backup?
A: Ebiseera ebisinga, yee - naddala ku bifo ebitambula ennyo, ebirina ekifo ekitono, ebyetaaga okuddaabiriza okutono, oba ebijja okubeera mu buweereza okumala emyaka 10 oba okusingawo. Bbeeyi y’okugula esingako etera okusasulwa olw’obulamu obuwanvu obw’okuweereza, okukyusakyusa okutono, ssente entono ez’okuddaabiriza, n’obunene bwa kabineti obutono. Lead-acid ayinza okusigala nga ya ssente-effective for short-backup ku indoor, embeera y'obudde-okufugibwa ebifo ebitatera kuvuga obugaali.
Q: Kiki Abaddukanya Balina Okukebera Nga tebannakyusa Battery za Lead-Acid Ne Lithium?
A: Kakasa nti enkola ya rectifier eriwo esobola okuwagira bbaatule ya lithium’s charge voltage profile. Obutoffaali bwa LiFePO4 bulina charge curve ey’enjawulo okusinga VRLA, era rectifiers ezimu enkadde ziyinza obutakwatagana awatali firmware update oba dedicated lithium charger module. Era kakasa nti enkola y’empuliziganya ya BMS (SNMP, Modbus, CAN bus) ekwatagana ne site controller, era nti DC circuit breakers eziriwo ziweebwa ekipimo kya fault current ya battery bank empya.
Q: BESS Ya Telecom Esobola Okukwatagana Ne Solar Panels Ne Generators?
A: Yee. Enkola z’omugatte gwa bbaatule-jenereta z’enjuba-zeeyongera okuba ez’omutindo ku mikutu gy’amasimu egy’ebweru-grid n’egy’amasimu enafu-grid. BESS etereka amaanyi g’enjuba emisana, egaba omugugu ekiro, era ekwatagana n’enzikiriziganya ya jenereta ey’okutandika oto-okukuuma amaanyi mu biseera ebiwanvu eby’omusana omutono-. Okugatta obulungi kyetaagisa okukwataganya ekifulumizibwa ekifuga chajingi y’enjuba n’ebipimo bya chajingi ya bbaatule n’okukola pulogulaamu ku mitendera gy’okutandika/okuyimirira kwa jenereta okusinziira ku SoC ya bbaatule.
Q: Mitindo Ki egy’Amakolero Egikola Ku Nkola z’Amasannyalaze Agatereka Amasimu?
A: Emitendera emikulu mulimu ETSI EN 300 132-2 (−48 V DC power interface for ICT equipment), ITU-T L.1200 series (DC power feeding for telecom), ITU-T L.1397 (okulondoola n’okufuga interface ku nkola za bbaatule), ne NEBS (Network Equipment-Building System) okusobola okugumira obutonde n’ensi. Obukuumi bwa bbaatule era buyinza okugwa wansi wa IEC 62619 (ebyetaago by’obukuumi ku butoffaali bwa lithium obw’okubiri mu mirimu gy’amakolero) ne UL 1973 (bbaatule ezikozesebwa mu bifo ebitali bimu).
Mu bufunzi
Enkola y’okutereka amaanyi ga bbaatule y’amasimu si ya kutereka yokka - gwe musingi gw’okubeerawo kw’omukutu. Buli ssimu esuuliddwa, olutuula lwa data olulemererwa, n’okusubwa okutambuza okw’amangu mu kiseera ky’amasannyalaze okuvaako bikiikirira omuwendo obutereevu eri omuddukanya n’ebitundu ebisinziira ku kuyungibwa.
Okulonda enkola entuufu kitegeeza okukwataganya kemiko ya bbaatule, obusobozi, okuddukanya ebbugumu, n’okulondoola okusinziira ku mugugu gwa buli kifo ogw’enjawulo, ebyetaago by’obwetwaze, embeera z’obutonde, n’enkola y’emirimu ey’ekiseera ekiwanvu-. Enkola y’okugerageranya obunene, emmeeza y’okusalawo ku kika ky’ekifo-, n’okukebera okugatta ebyogeddwako mu kitabo kino biwa entandikwa entuufu eri abaddukanya amasimu, ttiimu z’okugula, ne bayinginiya ba pulojekiti nga beetegereza okuteekebwa mu nkola kwabwe okuddako okwa BESS.
Nga tonnalambika nkola, pima emigugu gy’omukutu gwo, tegeeza ebiruubirirwa byo eby’obwetwaze, okwekenneenya ebiziyiza byo eby’obutonde, era obala omuwendo gwonna ogw’obwannannyini mu bulamu bw’obuweereza obusuubirwa mu bujjuvu. Nga olina dizayini entuufu, BESS y’amasimu ekendeeza ku budde bw’okuyimirira, esala ku nsaasaanya y’emirimu, era ewagira okubeerawo kw’omukutu abakozesa n’abalungamya kwe baagala.
