1.1 Tlhaloso ea Morero

Ka 2024, k'hamphani ea rona e ile ea fana ka tse 37single-phase pad-lima li-transformerho moreki oa Jamaica. Sena se kenyelelitse likarolo tse 2 tsa mohlala oa 25 kVA, haholo-holo ho fana ka lihlahisoa tsa kabo ea motlakase libakeng tsa bolulo tsa lehae. Scotech e hlophisitse tharollo e nepahetseng ea transformer ho fihlela litlhoko tsa bareki. Likarolo tsohle li entsoe ho latela maemo a IEEE, ho netefatsa ts'epo le ts'ebetso ea nako e telele-.

Motlakase oa mantlha (o phahameng) ke 24GrdY/13.8 × 12GrdY/6.9 kV, e leng moralo o habeli- oa motlakase. Bareki ba ka switjha pakeng tsa 13.8 kV le 6.9 kV ba sebelisa sesebelisoa sa ho khetha tse peli-ho itšetlehile ka mohala oa ho ajoa. Ha e na{10}}load tap changer (NLTC) ±2×2.5% bakeng sa ho lokisa motlakase. Motlakase oa bobeli ke 0.24/0.12 kV, o loketse malapa le likhoebo tse nyane. The loop{17}}feed, e seng e felile{18}moetso o ka pele o etsa hore instola e bolokehe le ho be bonolo.

25 kvapad mounted transformere sebelisa li- windings tsa koporo, pholiso ea ONAN, le ho kenya liminerale oli. E sebetsa ka katleho mme e nka nako e telele maemong a tropike. Li sebetsa ka lebelo la 50Hz, li-transformer tsena li fumana tahlehelo e kholo ea{3}}ea 0.078 kW le ho{5}tahlehelo ea 0.165 kW.
Tšireletso le tšireletseho li tiisetsoa ka likarolo tse tloaelehileng tse kang fuse ea bayonet, fuse e fokolang ea hona joale (CLF), le sesebelisoa sa ho fokotsa khatello, se nang le mochine oa boithaopo le mochine oa ka hare oa phoso (IFD) bakeng sa ho tšepahala ho ntlafetseng.
Ka ho kopanya-masebetsi a boleng bo holimo, moralo o kopaneng, le likarolo tsa ts'ireletso tse tsoetseng pele, transformer ena e loketse marang-rang a sejoale-joale a phanoang. E fana ka matla a tsitsitseng, a sebetsang hantle le a sireletsehileng ho sechaba sa lehae.

Transformer ena ea 25 kva pad e entsoe ka mapheo a matla a koporo le mokokotlo oa leqeba o fanang ka tahlehelo e tlase le lerata le tlase. Tanka e hahiloe hore e lule e bolokehile ebile e notletsoe, leha lithapo li hoketsoe. Yuniti e na le-moetso o habeli oa motlakase le mochini o fetolang 'me o tla u thusa ho o lokisa habonolo. E sebetsa hantle libakeng tse chesang le tse mongobo tse nang le pholiso ea ONAN le ho kenya liminerale oli. E nyane ka boholo empa e matla ha e sebelisoa. E tla le li-fuse tse tloaelehileng, sesebelisoa sa ho imolla khatello, 'me e ka eketsa likhetho tse ling tse kang li-surge arresters le li-detectors tsa liphoso.

Transformer ena e bonolo, e bolokehile ebile e ka tšeptjoa. E fana ka matla a tsitsitseng ho malapa le likhoebo tse nyenyane. E boetse e nka nako e telele mme e hloka tlhokomelo e fokolang. Ke khetho e ntle bakeng sa tšebeliso ea matla ea lehae Jamaica.
