01 Kakaretso

1.1 Tlhaloso ea Morero

Ka 2024, moreki oa Canada o ile a etsa odara ea li-transformer tse ka pele tse 300 tsa KVA tse entsoeng le ho etsoa ka tumellano e felletseng le CSA Standard C227.4:21. Li-transformer tsena li hahiloe molemong oa ts'ebetso e ts'eptjoang kantle, -litsamaiso tsa phepelo e feptjoang tse nang le marang-rang a thehiloeng hantle.

Ho fanoe ka 300 kVA -phase phase pad-mounted transformer e le karolo ea morero ona. E na le{4}}moralo o sa bonahaleng o ka pele o netefatsang polokeho le ts'ebetso e bonolo. Mokhoa oa ho pholile ke ONAN, o fana ka ho senya mocheso o ka tšeptjoang tlas'a maemo ohle a mojaro. Transformer e sebelisa li-insulation tsa oli ea diminerale le mapheo a aluminium, e fanang ka teka-tekano e ntle pakeng tsa ts'ebetso e phahameng le litšenyehelo. E lekantsoe ho 300 kVA, 60 Hz, e nang le motlakase o ka sehloohong oa 12.47 / 4.16 kV le motlakase oa bobeli oa 0.208 kV.

Khokahano ea matsoelintsoeke ke YNyn0, e loketse marang-rang a kabo e thehiloeng. No-load tap changer (NLTC) e fanwe ka ±2×2.5% ya ho theipisa. Sena se lumella phetoho e bonolo ea voltage ho tsamaisana le maemo a fapaneng a ts'ebetso le ho netefatsa ts'ebetso e tsitsitseng ea sistimi. Transfoma e sebetsa hantle ka 98.94%, ha e{8}}tahlehelo ea mojaro Ka tlase kapa ho lekana le 800 W le tahlehelo ea thepa Ka tlase kapa ho lekana le 3580 W. E na le lisebelisoa tse lumellanang le CSA{12}}le moralo oa maoto a 5 bakeng sa ts'ebetso e tsitsitseng tlas'a khokahanyo e thehiloeng ho Y–Y.

Tlhahiso ena e bonahatsaBoitlamo ba SCOTECH ba ho fana ka-ka boleng bo holimo, CSA-li-transformer tse netefalitsoeng tse etselitsoeng 'maraka oa Canada oa kabo ea motlakase.

02 Tlhahiso

2.1 Lesupa la Boemo ba Oli

Letšoao la boemo ba oli le u lumella ho bona oli ea li-transformer tse 300 tse shoeleng ha u habanya, ka nako ea 'nete, kahoo ua tseba hore na ke moo e lokelang ho ba teng. Oli ha se feela sekontiri-e tlosa mocheso ho tloha mapheong a matsoelintsoeke le mantlha. Haeba boemo bo theoha, e ka ba ho lutla, kapa ho na le ho hong ka hare ho phoso. Ka lintlha tse bonoang kapa li-sensor, basebelisi ba ka eketsa kapa ba hlahloba kapele, ba thusa ho thibela ho hloleha le ho lelefatsa bophelo. Hangata e kenngoa moo ho leng bonolo ho e hlahloba, e etsa hore tlhahlobo ea letsatsi le letsatsi e bolokehe le ho ba bonolo.

2.2 IFD & Drain Valve

Internal Fault Detector, IFD, le valve ea drain e 'ngoe le e' ngoe e na le karolo ea eona, empa hammoho li boloka transformer e bolokehile. IFD e utloa likhase tse sa tloaelehang kapa mats'oao a manyane a arc, e lemosang mabapi le litaba tsa matsoelintsoeke kapa ho kenya letsoho pele ho nako. Sesepa sa drain se u lumella ho tlosa oli, bakeng sa tlhokomelo ea kamehla kapa maemo a tšohanyetso. Ka bobeli, o ka fumana likotsi esale pele mme oa sebetsana le oli ka mokhoa o sireletsehileng. Haholo-holo ho tse tharo-li-transformer tsa mekhahlelo, litemoso tse nakong le taolo ea oli e laoloang li thusa ho boloka tsohle li tsitsitse le ho qoba mathata a maholo ho theosa le moeli.

2.3 Valofo e Imollang Khatello le Sekala sa Vacuum Pressure Gauge

Ka har'a transformer, valve ea ho fokotsa khatello le sekhahla sa khatello ea vacuum se sebetsa joalo ka sehlopha se senyenyane sa polokeho. Belofo ea liphallelo{1}}e buleha ha khatello ea khase e nyoloha haholo; e sireletsa tanka, litiiso. Vacuum gauge-e bontša ho fetoha ha khatello, lintlha tsa ho fetoha ha mocheso, katoloso ea oli, mohlomong le mathata a ho koala. Hammoho, chebahalo e potlakileng e fa basebelisi setšoantšo se akaretsang. Spot overpressure, khatello e mpe pele ho nako; e thusa ho boloka li-insulation, likarolo tsa mochini. E bohlokoa haholo-mohatong oa li-transformer, moo phoso e le 'ngoe e ka amang yuniti kaofela.

 

2.4 Thermometer

Thermometer e latela mocheso oa oli le matsoelintsoeke, e bonts'a hore na transformer e chesa hakae. Mocheso o phahameng o senya oli kapele, o hatella ho koala, 'me o ka sebetsa ho feta tekano. Ho shebella 'malo ho thusa basebelisi ho etsa qeto ea ho fokotsa mojaro, ho kenya moea o mongata, kapa ho rera ho lokisa. Lintlha li ka hlahlojoa ka letsoho kapa tsa kenngoa lits'ebetsong tsa ho beha leihlo. Bakeng sa likarolo tse tharo-ho bohlokoa ho bona mocheso oa karolo ka 'ngoe, ho boloka lintho li tsitsitse, ho qoba lintho tse makatsang, le ho etsa bonnete ba hore matla a lula a phalla butle.
