Indima eyodwa ebalulekile ngenkathi ubhekha um- uninterruptible Power Supply (UPS) okufanele usebenzise kumasevisi ase-B2B izindawo zedatha , amapostu ase-telekom, izindawo zokusebenza, noma imithambo yezilwanyana, kukhona isimo sesikhala sezinkulungwane zokugcina amandla. Izinhlangano zokugcina amandla zezihigh nezilow voltage (400 V ukuya ku-800 V DC, kanye ne-48 V ukuya ku-220 V DC, ngokulandelana) zinamathuba awo. Ukuze uqinisekise ukuthi inkulungwane yakho yokugcina amandla iyasebenza ngokuphelele, kubalulekile ukuzijabula izinkinga phakathi kwefficiency, isafuthi, nokuhambisana nomsebenzi.
Ukulinganisa i-Efficiency Phakathi Kwezinhlangano Zokugcina Amadla Zesi-High Voltage Nezilow Voltage
Izinhlangano zokugcina amandla zokusebenza ngemithambo yezihigh voltage zinamandla amaningi, ikakhulu ngenkathi zisebenza ngamandla amaningi. Izinhlangano zesi-high voltage zinamandla 94–97% yokuqhubeka kwesikhathi sokubuyela , uma kuqhathaniswa no-88-92% ngezinhlelo zamandla aphansi ezitshalweni ezinkulu, ezingaphezu kuka-100kW. Lokhu kungenxa yamanje encane, njengoba i-voltage ephezulu ivumela amandla aphansi amandla afanayo, anciphisa ukulahleka kokumelana (I2R) ezintanjeni, izixhumi, nama-busbar. Izinhlelo zamandla aphakeme nazo zingakwazi ukuhlanganiswa ngqo nama-lithium battery racks anamuhla ngaphandle kokulahlekelwa ukuguqulwa okuhambisanayo. Amabha we-basbar wethusi aminyene kakhulu ayadingeka ukuze asekele imisinga ephezulu (isb. 1,000A + ukusekela ama-50kW) ezinhlelweni zamandla aphansi, ikakhulukazi kuma-48V, okuholela ezindlekweni eziphakeme zokufakwa kanye nokulahleka. Ezakhiweni ezibalulekile lapho zisebenza khona ubusuku nemini, amahora angu-24 ngosuku, ukusebenza kahle kwamandla aphakeme angu-5-8% kuholela ekulondolozeni izinkulungwane zamaRandi kagesi ngonyaka.
Ukucatshangelwa kokuphepha kwe-High Voltage UPS Izakhiwo Ezindaweni Zemboni
Izisikhangeli zesikhundla se-UPS esisebenzisa amavolt ezinkulu kufunele kube nesikhundla sesafuthi esikhulu. Amavolt amaningi (ngaphezulu kwe-400 V DC) kufunele kube nesikhundla sesafuthi esingaphansi: ukuchaza kwezinyathelo zokuphuma kwamandla, izintshayezo ezingasemthwakweni, izindawo zokufinyelela okugcinwe, nokufundisa okuhle kwebhodi yokuqinisa. Kepha, izisikhangeli sezinkulu zamavolt esihlombe, zinikeza izisikhangeli sezinkulu zokusebenzisa ibhayithi (BMS) esisebenzisa ukugcina ngokusebenzisa izicabho, ukucindezela kwezinyathelo zokuphuma kwamandla kuzonke iziqhelo, nokubhekisa ukungabi nesibindi kwezinyathelo zokuphuma kwamandla (IMD) okuvumela ukuthi kubonwe ukungabi nesibindi kwezinyathelo zokuphuma kwamandla kabefore ukuba kwenze isibindi. Izindawo ezingaphansi ezingenayo izindawo zokusebenzisa amandla angaphansi kuyizindawo eziphakeme kakhulu ngokusebenzisa izisikhangeli zokusebenzisa amandla angaphansi (48V-110V) ngoba ziyisafuthi kubantu abasebenza ngaphakathi kwezindawo zokubuka ngokuphakeme. Ngempela, emazwe okusebenza apho abasebenzi abangafundiswanga, noma apho abasebenzi bakhubeka izinto zokusebenzisa amandla ngokuphakeme, isibindi sokukhulula amandla sifakwa phansi ngokusebenzisa amandla angaphansi. Ngenkathi, izindlela zokusebenzisa amandla angaphezulu emazwe okugcinwa, njengoko kusetyenziswa izindawo zokusebenzisa ibhayithi ezingagcinwa ngokuphakeme nokugcinwa kokufinyelela, nokusebenzisa izintshayezo ezifanele, zisetyenziswa kahle futhi zibonakala njengokusebenza kahle emazwe amaningi okusebenza kwe-telekomunikhesi nezindawo zokugcina idatha emazwe wonke. Lokhu kuzobhekwa ngokubonakalayo kwezinhlobo zokugcina isafuthi nezinhlobo zokufunda kwezindawo zakho.
Iyiphi i-Voltage yebhatari ye-UPS eyizinga elikhulu kuma-data centers futhi Imithambo ye-telekomunikhesi ?
Kukhona imithambo ye-data centers, izinhlelo ze-UPS zemithambo emkhulu (400 V–800 V DC) ziyabecala ukuba ziyizinhlelo eziphakeme. Zibhekene ngokuphelele ngezinhlelo zezindawo zokusebenza (200kW–2MW), zingaphansi kakhulu kwezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampan......
Ngaphandle kakhulu imithambo ye-telekomunikhesi , kuyisahluko sokubhekana nesilinganiso. Imitambo emkhulu (240 V–400 V) iyasebenzisa kakhulu emaphoyinti amakhulu we-DC (10kW–100kW) ukuze kutholwe ukuphelele kwezinhlelo zokusebenza. Kepha imithambo yezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo zokusebenza zezindawo z...... izinhlelo zemithambo emncane ye-48V DC , indlela eyayisisekelo yendustria yezinkampani zokuthumela amazwi ngeminyaka engaphezu kwezinkulungwane. I-48V ayikho kubangelwa njengokuthi kuyisibonelo sokungatholakali kubantu abasebenza emhlabeni ngaphandle kokulawulwa, futhi isikhundla se-48V sokugcina amandla, amabhatteri, nabahlanganisi bokugcina amandla sibekwe kahle futhi sibizwa kuzo zonke izindawo. Abashishini abaningi bezinkampani zokuthumela amazwi bavula amandla emkhakha yokuqonda ngokusebenzisa i-48V, futhi amandla okuphakathi ayasebenza ngamandla amaningi.
Isiphetho
Khetha i-high voltage UPS emadatalayiseni amakhulu nasezindaweni zokuvula amandla apho ukusebenza kanye nokunciphisa indawo kuyisibonelo sokuthi kufanele kwenziwe izindlela zokulawulwa zokuphepha kwezinto eziningi. Sebenzisa amandla angaphezulu (48V) emkhakha yokuqonda yezinkampani zokuthumela amazwi, emazindaweni angaphezulu kanye nezindawo ezingaphansi apho ukuphepha kwabantu abasebenza kanye nokuphepha kwezikhundla zokusebenza kuyisibonelo esikhulu kakhulu. Kuzindawo zokusebenza ngokujabulisana, i-Shenzhen Weitu Hongda Industrial Co., Ltd. inikeza izisombululo sezinkampani zokuvula amandla nasezinkampani zokugcina amandla ngokuhambisana nezinhlobo zomandla, ngezicertifiketi ze-ISO nase-CE. Qhagamshelani nathi ukuze sibhekise isikhundla sokuvula amandla esikhundla sakho.
