Yolandirana apano - zosiyanasiyana ndi chipangizo

Current kulandirana - chipangizo kuti ambiri ntchito polengeza panopa kuposa wina ankalamulira dera. Ndiponso, ntchito kuletsa dera mu chochitika madera yochepa kapena overloads. yolandirana Undercurrent ntchito kwambiri kamodzikamodzi. zipangizo amenewa anapangidwa kuti akugwera dera magetsi pamene ena osachepera mtengo panopa.

Pali mitundu yosiyanasiyana ya zipangizo zamagetsi monga masiwichi mphamvu. Iwo amasiyana yomanga ndi opareshoni mfundo. Ngati ife kulankhula za otchedwa chida chakale, ndi nangula makina pa akasupe, amene akulamulira kulankhula ndi koyilo pachimake (zambiri chitsulo). Pamene panopa umadutsa koyilo ndi kutitengera maginito chikuperekedwa ena. Za ntchito ya munda maginito ndi maginito ndi koyilo pachimake akuyamba kukopa armature. Choncho, kulankhula ndi zidzayambike.

The koyilo chipangizo zizindikiro windings ochepa, koma ali ndi lalikulu awiri waya (monga kuyenera, mwachitsanzo, ndi yolandirana chomwecho voteji). The awiri a waya zimadalira panopa, kapena zambiri ndendende, ukulu wa mtengo wake woikidwiratu panopa. Izi amakwaniritsa ndi voteji dontho. Ichi ndi chofunika kwambiri, chifukwa koyilo ndi chikugwirizana mu nkhani ku dera ankalamulira.

Ena yolandirana DC ndi chosinthika ulendo panopa. Nthawi zambiri izi zimatheka ndi kusintha maganizo armature masika. Kulandirana AC, amene ntchito pofuna kuchepetsa mafunde mkulu akhoza anazimitsa kudzera tiransifoma.

Khalidwe zofunika kwambiri pogwiritsa zoteteza akuchitanji nthawi. Zipangizo za mtundu uwu kuti angagwiritsidwe ntchito chitetezo madera lalifupi ndi kusinthitsa nthawi ya osapitirira makumi angapo milliseconds.

Olimba boma kulandirana DC dera amachita mwamsanga pamene sakukhudzidwa. Izi kumatha kuthekera positives zonama nkhani ya yochepa nthawi ukuwonjezeka panopa. chipangizo wotero zambiri amalamulira nthawi opaleshoni.

Za mtundu wina ambiri zipangizo zodzitetezera ndi matenthedwe kulandirana panopa. Ndi bimetallic mbale, anapereka ndi Kutentha mchitidwe opangidwa ndi nsalu atavala resistivity mkulu (mwachitsanzo, nichrome). mbale wapangidwa ndi zipangizo ndi koyefishienti osiyana cha kuwonjezedwa ikukhudzana amene anaŵerama pa Kutentha ndi kumachita pa limagwirira lophimba. Kuyankha nthawi ya chipangizo choterocho chimadalira pa apano - apamwamba ilo liriri, mofulumira kutenthetsa mbale, ndiponso mmene nthawi ang'onoang'ono.

Amagetsi overcurrent kulandirana ntchito pafupifupi yomweyo zimamuchulukira tripping. kulandirana dera pakompyuta akhoza pokonza zizindikiro malinga ndi magawo anakonzeratu ndi makhalidwe pasadakhale. Mukhoza anapereka kololeka pazipita panopa ndi nthawi mwamsanga pamene disconnecting. Chotero yolandirana panopa akhoza kukhala zosintha ndi zokhazikika. zipangizozi zambiri mu mawonekedwe a anamanga-zipangizo zambiri.
