Ma Transformers Okhazikika pa JZP Single-Phase Pad: Uinjiniya Wolondola Wogawa Mphamvu Modalirika​

Mu gawo la uinjiniya wamagetsi, njira yogawa magetsi imagwira ntchito ngati mgwirizano wofunikira pakati pa kutumiza mphamvu ndi kugwiritsa ntchito mphamvu. Kumvetsetsa bwino chidziwitso chogawa magetsi, makamaka chokhudza switchgear, ndikofunikira kwambiri kwa mainjiniya amagetsi ndi akatswiri. Switchgear ndi chipangizo chogawa magetsi chophatikizidwa chomwe chimasonkhanitsidwa motsatira njira zinazake zoyendera magetsi, kuphatikiza zida zoyambira (monga mabasi, zotsekera magetsi) ndi zida zina (monga zotumizira magetsi, zoyezera magetsi). Ntchito yake yayikulu ndikuwongolera ndikuteteza mizere ndi zida zogawa magetsi, kuonetsetsa kuti makina amagetsi akugwira ntchito bwino komanso mokhazikika.

 

Kugawa kwa Switchgear

Switchgear ikhoza kugawidwa m'magulu kutengera zofunikira pakugwiritsa ntchito ndi kuchuluka kwa magetsi:

 

Mwa Kapangidwe: Mitundu yokhazikika komanso yotha kuchotsedwa (ngolo yonyamula katundu).

 

Ndi Voltage Level:

 

​Chida Chosinthira Champhamvu Kwambiri: Chimaphatikizapo mapangidwe okhazikika komanso otha kuchotsedwa.

 

​Chida Chosinthira cha Voltage Yotsika: Chimaphatikizapo mapangidwe okhazikika komanso a mtundu wa ma drawer.

 

Zigawo za Kapangidwe ka Switchgear

Switchgear nthawi zambiri imakhala ndi madera ogwirira ntchito otsatirawa, olekanitsidwa ndi mbale zachitsulo zomangiriridwa kuti zisawononge mafunde afupiafupi:

 

Chipinda cha Mabasi: Nyumba za mabasi (oyendetsa mabasi).

 

Chipinda Chosinthira Ma Circuit: Chili ndi chosinthira ma Circuit chachikulu.

 

Chipinda Chachiwiri Chowongolera (Chipinda cha Zida): Ma relay a nyumba, mita, ndi zida zowongolera.

 

Chipinda Chodyetsera: Chimalumikiza ma feeder otuluka.

 

Zigawo Zamkati Zofunika:

 

Mabasi (oyendetsa mabasi)

 

Zosokoneza dera

 

Ma relay achizolowezi

 

Zipangizo zotetezera zolumikizidwa

 

Mamita

 

Kupatula maswichi

 

Zizindikiro

 

Zosintha za nthaka

 

Magulu Ogwira Ntchito a Switchgear

​1. Kabati Yolowera (Kabati Yolowera)​​

Udindo: Amalandira mphamvu kuchokera ku gridi ndikuigawa ku zida zina kudzera mu ma circuit breakers, ma CT (Current Transformers), ndi ma PT (Ma Transformers a Voltage).

 

Kufunika: Imagwira ntchito ngati njira yolumikizirana yayikulu ya gridi.

 

​2. Kabineti Yotuluka (Kabineti Yogawa)​​

Udindo: Kugawa mphamvu kuchokera pa basi kupita ku mizere yotuluka, kuonetsetsa kuti zida zogwiritsidwa ntchito zikupezeka bwino.

 

​3. Kabati Yolumikizira Mabasi​

Udindo: Kulumikiza magawo awiri a basi, kuthandizira machitidwe a basi imodzi kapena awiri kuti azitha kugwira ntchito mosavuta.

 

​4. Kabati ya PT (Chosinthira Chothekera Kabati)​​

Udindo: Imayang'anira magetsi a busbar ndipo imathandizira machitidwe oteteza. Ili ndi ma PT, ma switch olekanitsa, ma fuse, ndi zoletsa ma surge.

 

​5. Kupatula Kabati​

Udindo: Umapereka malo owonekera olumikizirana kuti akonze, kusiyanitsa mabasi kapena zida kuchokera ku magetsi. Umafunika kulumikizidwa ndi ma circuit breakers kuti upewe kugwira ntchito mwangozi.

 

​6. Kabinet Yolipirira Capacitor​

Udindo: Kumawongolera mphamvu zamagetsi ndikuchepetsa kuwononga mphamvu kudzera mu reactive power compensation.

 

​7. Kabati Yoyezera​

Udindo: Amayesa kugwiritsa ntchito mphamvu (kWh) pogwiritsa ntchito mita, ma CT, ma PT, ndi zida zothandizira monga zowunikira katundu.

 

​8. Kabati ya GIS (Switchgear Yotetezedwa ndi Gasi)​

Udindo: Kugwiritsa ntchito mphamvu zamagetsi/mphamvu kwambiri pogwiritsa ntchito mpweya wa SF6 kuti uteteze mpweya, kuonetsetsa kuti chitetezo ndi kudalirika kwawonjezeka.

 

Zigawo Zofunika Kwambiri ndi Ntchito Zawo

Woswa Circuit

Ntchito: Kulumikiza/kuchotsa ma circuit pansi pa mikhalidwe yabwinobwino ndikusokoneza ma current currents (monga ma circuit afupi).

 

Kuzimitsa Arc: Amagwiritsa ntchito zinthu monga mpweya wa SF6, vacuum, kapena mafuta kuzimitsa arcs panthawi yozimitsa.

 

​Kusintha Kosiyana (Chochotsera)​​

Ntchito: Imachotsa bwino ma circuit amphamvu kuti isawonongeke. Siimatha kuswa magetsi; iyenera kugwiritsidwa ntchito ndi ma circuit breaker.

 

Fuse

Ntchito: Imateteza ma circuits mwa kusungunuka ngati mafunde akupitirira, zomwe zimafuna kuti asinthidwe pambuyo pa ntchito.

 

​Chosinthira Katundu​

Ntchito: Imalepheretsa mafunde ochulukirapo koma osati mafunde afupiafupi. Nthawi zambiri imagwirizanitsidwa ndi ma fuse kuti ateteze mafunde ochulukirapo.

 

Transformer

Ntchito: Imasintha milingo yamagetsi pogwiritsa ntchito njira yopangira magetsi. Magawo ofunikira ndi monga mphamvu yovotera, chiŵerengero cha magetsi, ndi magwiridwe antchito.

 

Mapeto​

Kudziwa bwino mfundo za switchgear—kuphatikizapo kapangidwe kake, zigawo zake, ndi ntchito zake—ndikofunikira kwambiri kuti makina amphamvu azidalirika komanso otetezeka.
