Ndi zingalowe lophimba Kodi

Panopa anthu ambiri ikuchitika m'malo a mafuta ndi gasi amalimata breakers dera ndi breakers zingalowe dera. Mtundu wa switchgear n'cholinga chofuna kuteteza mphamvu dera ku madera lalifupi ndi overloads zimatiyika voteji 10 kV ku 220 kV. The zifukwa m'malo zida chifukwa osati ntchito kuwonongeka ndi obsolescence. Mafuta dera breakers ili yaing'ono gwero azima, m'pofunika kuti aziona mlingo mafuta, ndi kukhazikitsa actuators mphamvu kupereka chofunika opaleshoni liwiro. Komanso, pali chiopsezo kuphulika pa ndondomeko shutdown.

Nawonso masiwichi gasi amalimata amathandiza kuti chitukuko cha mmene kutentha, amakhala ovuta kubala ndi kuyiyendetsa. Masiwichi wa mtundu uwu ndi mtengo, amafuna polojekiti ntchito sulfure hexafluoride, komanso zofuna okwera pa khalidwe la mafuta jekeseni.

Ubwino nawo breakers zingalowe dera zotsatirazi:

1. zachilengedwe chitetezo.

2. ambiri ntchito kusintha.

3. Low ndalama opaleshoni.

4. kuphweka kulengedwa.

5. High kudalirika.

6. Small kukula.

7. Zipangizo ndi moto.

8. Palibe kuipitsa phokoso.

The kuipa kwa breakers zingalowe dera ndi:

1. wotsika oveteredwa mafunde osinthasintha mafunde.

2. Mwina kusinthitsa kukakhala.

Development wa zingalowe kusintha zipangizo nawo mayiko, monga Japan, China, Russia, etc.

Zingalowe m'malo dera baka ichidachi akhoza ankaimira akasinja ndi ntchito pachimake. Mbali yoyamba udindo ankaimba ndi kudzipatula mpweya youma amene jekeseni opanikizika. Izi zimathandiza kuti kusinthana zingalowe m'malo otetezeka kwambiri chilengedwe. Mbali yofunika kwambiri ya mamangidwe thanki ndi chakuti pamene dismantling si kofunika malizitsani chimateteza mpweya sing'anga.

Zingalowe m'malo dera baka ichidachi mwina yopuma chimodzi kapena zingapo pa mtengo wina. Izi zikutanthauza kuti dera magetsi adzakhala linasokonekera pa malo angapo othetsa zikuchitika arcing zinachitika mosabvuta.

Mavuto mpweya youma ndi wofanana 5 atmospheres, chifukwa pa mfundo yaikulu ya Arc othetsa chipinda, amene anaika mu zingalowe m'malo dera baka ichidachi angasiye bata ake ndi sathanso olumala. Komabe, akukhulupirira kuti akufa thanki zingalowe dera baka ichidachi kwambiri kuposa Kolinsky lophimba kamangidwe.

Ndondomeko kuzimitsa Arc magetsi mu zingalowe dera baka ichidachi chiri motere: a kotenga maginito ndi superimposed pa Arc anakafika mu chipinda zingalowe interrupter. Izi amalenga zotsatira za otchedwa kotenga maginito nkhonya, potero kukula kutalika Arc kumachitika. Monga amadziwika kwambiri, kutalika waku Arc, ndi zosavuta kulipira. Pa nkhani imeneyi, Arc voteji ali ndi chikoka chachikulu pa miyeso ya magetsi, chifukwa apamwamba a voteji, wamkulu kukula Arc chipinda ndipo potsatira miyeso lalikulu ayenera kukhala unsembe lonse wonse.

Yotsegulira maelekitirodi masika pagalimoto ikuchitika, akasupe yomwe ikuchitika ndi electromagnet ndi.
