1.1 Tlhaloso ea Morero

Li-transformer tsena tsa 75 kVA -tse phahamisitsoeng ka lipalo tse entsoeng ke Scotech.Li-transformer{{0}tse palamisitsoeng ka polatheola{{0}motlakase o matla oa motlakase ho ea maemong a loketseng malapa le likhoebo tse nyane, ho netefatsa phepelo e tsitsitseng ea motlakase litoropong le mahaeng. Li-transformer tsena li romelloa Canada, li lumellana ka botlalo le litekanyetso tsa IEEE C57.12.20 le ho finyella litlhoko tsa morao-rao tsa tšebeliso ea matla a matla.

Taelo e kenyelletsa likarolo tse 8 tsa transformer ea 75 kVA. Yuniti ka 'ngoe e etselitsoe motlakase o phahameng oa 7.97/13.8Y kV le motlakase o tlase oa 120/240 V mokhahlelo{7}. E na le lihlahla tse peli tse phahameng tsa motlakase le lihlahla tse tharo tse tlase tsa motlakase, transformer e netefatsa ts'ebeletso e tšepahalang bakeng sa lits'ebetso tsa khoebo tsa bolulo le tse bobebe.

Transformer e fana ka libaka tse 'ne tsa ho penya ka lehlakoreng le phahameng la voltage e nang le mefuta e mengata ea ± 2 × 2.5%, e fanang ka lisebelisoa tse bonolo ho fetola motlakase ho latela maemo a mohala.

Ka tekanyo ea ho se sebetse hantle ea 2.1%, -tahlehelo e se nang moroalo oa 0.148 kW, le tahlehelo ea boima ba 0.675 kW, e bonts'a ts'ebetso e phahameng ea ts'ebetso le tahlehelo e tlase ea ts'ebetso. E sebelisa ONAN cooling, aluminium windings, le additive polarity, e etselitsoeng boholo bo kopanetsoeng le ho kenya poleiti e bonolo{5}}.

Transformer e boetse e na le mookameli oa surge arrester, e lumellang ho kopanngoa ha lisebelisoa tse sireletsang bakeng sa ts'ireletso e ntlafetseng le ho tšepahala ho marang-rang a kabo.
