Pazinthu zamagetsi zamagetsi ndi kuyeza, kulondola ndikofunikira. Chimodzi mwazinthu zofunika kwambiri zomwe zimathandizira kuyeza kolondola kwapano ndi shunt resistor. Mwazinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito popanga ma shunts, Manganin imadziwika chifukwa cha mawonekedwe ake apadera. Nkhaniyi ikufotokoza za chiyaniManganin amawomberandi, zipangizo ntchito shunts, ndi ntchito zawo enieni.
Kodi Shunt ndi chiyani?
Shunt ndi chigawo chochepa chokana chomwe chimayikidwa mofanana ndi chipangizo choyezera, monga ammeter, kulola kuyeza kwa mafunde apamwamba popanda kuwononga chida. Pogwiritsa ntchito lamulo la Ohm, kutsika kwamagetsi kudutsa shunt kumatha kuyeza, komwe kumagwiritsidwa ntchito kuwerengera komwe kukuyenda kuzungulira dera.
Ndi Zinthu Zotani Zomwe Zimagwiritsidwa Ntchito Pa Shunt?
Shunt resistors imatha kupangidwa kuchokera kuzinthu zosiyanasiyana, chilichonse chimapereka zabwino ndi zovuta zake. Zida zodziwika bwino ndi izi:
Mkuwa: Wodziwika bwino chifukwa cha madulidwe ake abwino, mkuwa umagwiritsidwa ntchito nthawi zambiri m'malo otsika. Komabe, kutengeka kwake ndi okosijeni kungayambitse zolakwika pakapita nthawi.
Nickel: Masamba a nickel ndi olimba komanso osagwirizana ndi dzimbiri, kuwapangitsa kukhala oyenera malo ovuta. Komabe, iwo si monga conductive monga mkuwa.
Manganin: Ichi ndi aloyi wopangidwa makamaka ndi mkuwa, manganese, ndi faifi tambala. Manganin imayamikiridwa makamaka pakugwiritsa ntchito shunt chifukwa cha kutsika kwake kwa kutentha kwa kukana, zomwe zikutanthauza kuti kukana kwake kumasintha pang'ono ndi kusinthasintha kwa kutentha. Kukhazikika kumeneku ndikofunikira kuti muyezedwe molondola.
Constantan: Aloyi ina, makamaka yamkuwa ndi faifi tambala, Constantan nthawi zambiri amagwiritsidwa ntchito mu thermocouples ndi shunts chifukwa cha kukhazikika kwake komanso kukana kwa okosijeni.
Kodi Manganin Shunt Amagwiritsidwa Ntchito Bwanji?
Manganin amawomberaamagwiritsidwa ntchito kwambiri m'machitidwe osiyanasiyana chifukwa cha mawonekedwe awo apadera. Nazi zina mwazogwiritsa ntchito poyambira:
Muyezo Wamakono: Manganin shunts amagwiritsidwa ntchito nthawi zambiri mu ma ammeter ndi zida zina zoyezera pomwe pamafunika kulondola kwambiri. Coefficient yawo yotsika ya kutentha imatsimikizira kuti kukana kumakhalabe kokhazikika, kupereka zowerengera zodalirika.
Miyezo Yoyezera: M'ma labotale, manganin shunts nthawi zambiri amagwiritsidwa ntchito ngati miyeso yoyezera zida zina zoyezera. Makhalidwe awo odziwikiratu pansi pamikhalidwe yosiyanasiyana amawapangitsa kukhala abwino pazifukwa izi.
Kuyeza kwa Mphamvu: M'makina amagetsi, manganin shunts amagwiritsidwa ntchito kuyeza mafunde akulu popanda kuyambitsa kutsika kwakukulu kwamagetsi. Izi ndizofunikira pakusunga magwiridwe antchito komanso chitetezo.
Kugwiritsa Ntchito M'mafakitale: Manganin shunts amagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza makina owongolera magalimoto ndi ma netiweki ogawa magetsi, pomwe kuyeza kolondola kwapano ndikofunikira kuti mugwire bwino ntchito.
Kafukufuku ndi Chitukuko: M'makonzedwe a R&D, Manganin shunts amagwiritsidwa ntchito poyeserera pomwe miyeso yeniyeni ndiyofunikira pakusonkhanitsa ndi kusanthula deta.
Mapeto
Manganin amawomberazimayimira gawo lofunikira kwambiri pakuyeza magetsi. Makhalidwe awo apadera a zinthu, makamaka kutentha kwawo kocheperako kukana, amawapangitsa kukhala abwino kwa mapulogalamu omwe amafunikira kulondola kwambiri komanso kukhazikika. Kaya m'mafakitale, ma laboratories, kapena makina amagetsi, Manganin shunts amagwira ntchito yofunika kwambiri powonetsetsa kuti miyeso yamagetsi ndi yodalirika komanso yolondola. Pamene teknoloji ikupitirirabe patsogolo, kufunikira kwa kuyeza kolondola kwamakono kudzangokulirakulira, kulimbitsa udindo wa Manganin shunts mu umisiri wamakono wamagetsi.
