Q1) Kodi chosinthira zida ndi chiyani?

Ngati tikufuna kuyeza mphamvu yamagetsi ndi mphamvu yamagetsi yapamwamba kwambiri, pali njira ziwiri zoyezera mphamvu yamagetsi. Njira yoyamba ndikugwiritsa ntchito zida zamagetsi zomwe zingakhale zodula kwambiri. Njira ina ndikugwiritsa ntchito mphamvu yamagetsi ndi mphamvu yamagetsi.

Mphamvu ndi magetsi zimatha kuchepetsedwa pogwiritsa ntchito transformer yomwe chiŵerengero cha kutembenuka kwake chimadziwika kenako kuyeza mphamvu ndi magetsi omwe atsitsidwa ndi ammeter kapena voltmeter yachibadwa. Kukula koyambirira kumatha kudziwika pochulukitsa kukula komwe kwatsitsidwa ndi chiŵerengero cha kutembenuka. Transformer yopangidwa mwapadera yotereyi yokhala ndi chiŵerengero cholondola cha kutembenuka imatchedwa instrument transformer. Pali mitundu iwiri ya instrument transformer:

1) Transformer yamagetsi

2) Transformer yomwe ingatheke.

Q2) Kodi ma transformer amakono ndi chiyani?

Transformer yamagetsi imayikidwa motsatizana ndi mzere womwe magetsi ayenera kuyezedwa. Amagwiritsidwa ntchito kutsitsa magetsi kufika pamlingo wotere kuti athe kuyezedwa mosavuta pogwiritsa ntchito ammeter. Nthawi zambiri amafotokozedwa ngati chiŵerengero cha magetsi apakati: achiwiri mwachitsanzo: CT ya 100:5 amp idzakhala ndi magetsi apakati a 100 Amp ndi magetsi apakati a 5 Amp.

Ma CT secondary ratings ndi 5 kapena 1 Amp.

Kugwiritsa ntchito kwa CT komwe kumapezeka pamsika ndi "clamp meter".

Q3) Kodi transformer yomwe ingathe kukhalapo ndi chiyani?

Ma transformer omwe angathe kusinthidwa amadziwikanso kuti ma voltage transformer ndipo kwenikweni ndi ma step down transformer omwe ali ndi chiŵerengero cholondola kwambiri cha ma turn. Ma potential transformer amatsika ma voltage amphamvu kwambiri kupita ku voltage yotsika yomwe ingayesedwe ndi chida choyezera wamba. Ma transformer awa ali ndi ma turn ambiri oyambira ndi ma turn ochepa owonjezera.

Transformer yomwe ingathe kugwiritsidwa ntchito nthawi zambiri imafotokozedwa mu chiŵerengero cha magetsi oyambira ndi achiwiri. Mwachitsanzo, 600:120 PT ingatanthauze kuti magetsi opitilira magetsi oyambira ndi 120 volts pamene magetsi oyambira ndi 600 volts.

Q4) Kodi pali kusiyana kotani pakati pa transformer yamagetsi ndi yamagetsi?

Pa mlingo woyambira, sizisiyana. Zonsezi zimagwira ntchito motsatira mfundo ya electromagnetic induction. Koma kusiyana kuli mu kagwiritsidwe ntchito kawo.

Ma transformer amagetsi, omwe ali mgulu la ma Instrument transformer, amagwiritsidwa ntchito kwambiri limodzi ndi zida zina poyesa. Monga momwe zilili ndi chida china chilichonse chomwe chimagwiritsidwa ntchito poyesa pamagetsi, ma transformer amagetsi ayenera kukhala ndi impedance yochepa kwambiri kuti asakhudze magetsi mumagetsi omwe akuyesa ndi kuchuluka kwakukulu. Komanso ndikofunikira kwambiri kuonetsetsa kuti kusiyana kwa gawo pakati pa magetsi oyambira ndi achiwiri kuli pafupi ndi zero momwe zingathere. Transformer yamagetsi ilinso ndi kutembenuka kochepa kwambiri, kapena ngakhale kamodzi pa magetsi oyambira ndipo ambiri pa magetsi oyambira.

Kumbali ina, ma transformer amphamvu amagwiritsidwa ntchito kusamutsa mphamvu kuchokera kumbali yoyamba kupita kumbali yachiwiri. Pano cholinga chachikulu si kuchepetsa impedance mu transformer, komanso kuchepetsa cholakwika cha phase angle pafupi ndi zero. Apa cholinga chachikulu ndi kuchita bwino kuposa kulondola. Kachiwiri, transformer yamagetsi imakhala ndi ma turn ambiri pa primary yake, kuposa kutembenuka kamodzi, ngakhale kuti imakhala yocheperako poyerekeza ndi ya sekondale.

Q5) Ndi makina ati omwe angapange transformer yamagetsi ndi yomwe ingatheke?

Pali njira ziwiri zopangira chosinthira chamagetsi cha epoxy resin, chakale ndi chachikhalidwe ndi chogwiritsa ntchito thanki yoponyera vacuum, yotchedwa ukadaulo woponyera vacuum, Ukadaulo wachiwiri waposachedwa ndi Ukadaulo wa APG (automatic pressure gelation) , Makina oponyera ndi makina olumikizira a APG, omwe amatchedwanso makina a APG, makina a epoxy resin apg, Tsopano makina a APG ndiye chisankho choyamba cha ogwiritsa ntchito. Chifukwa pansipa zabwino:

1. Kugwira Ntchito Mwachangu, Tengani chitsanzo cha 10KV CT, mutha kupeza CT yoyenerera mkati mwa mphindi 30.
2. Investment，Mtengo wa makina a APG pafupifupi 55000-68000USD
3. Kukhazikitsa, kumangofunika kulumikiza magetsi, ndiye kuti kumatha kuyendetsa makina
4. Magwiridwe Amagetsi, kutulutsa pang'ono, Kukana mankhwala, kutchinjiriza magetsi, kukana mphamvu kwakula kwambiri, tili ndi zida zoyesera.
5. Digiri Yodziyimira Payokha: Pakufunika antchito 1-2 okha kuti agwiritse ntchito makinawo, magwiridwe antchito amawonjezeka kwambiri koma mphamvu ya ntchito imachepa. Mukungofunika makiyi owongolera pa kabati yamagetsi.
6. Kugwira ntchito, N'kosavuta kugwiritsa ntchito makina a APG, mainjiniya athu adzatiwonetsa momwe tingagwiritsire ntchito makinawo ndipo tili ndi buku lothandizira kugwiritsa ntchito makina athu, palibe chifukwa cholipira ndalama zambiri kuti tilembe ntchito mainjiniya aluso kuti agwiritse ntchito makinawo.

Mutha kupita ku YouTube channel yathu, kuti muwone makanema ogwiritsira ntchito makina awa.
