Swetiyi imakhala yofunda kwambiri mukaivala, koma imanjenjemera mukaivula. Chifukwa chiyani? Kodi magetsi osasunthika a juzi akuyenera kuchotsedwa bwanji?
Chifukwa chake ndi chiyani
Sikuti kokha mukapaka ndi sweti kuti magetsi osasunthika amapangidwa. Malingana ngati zinthu ziwiri zikutsutsana, magetsi osasunthika amapangidwa, koma kukula kwa magetsi osasunthika kumakhala kosiyana. Mbali yofunika kwambiri ndi yakuti madulidwe a chinthu amatsimikizira kudzikundikira kwa magetsi osasunthika opangidwa ndi mikangano: kwa zipangizo zokhala ndi conductivity yabwino, static charge imafalitsidwa ndi kutayika nthawi; Zida zokhala ndi ma conductivity osauka sizingathawe pakapita nthawi magetsi osasunthika atapangidwa, motero amawunjikana ndikukupangitsani kumva.
Momwe mungachotsere magetsi osasunthika pamasweti
Njira 1: povula sweti kuti muyeretsedwe, onjezani zofewa, kapena mugwiritseni mwachindunji pa sweti ndi madzi ofunda ndi zofewa;
Njira 2: mutha kuwonjezeranso glycerin m'madzi, ndiyeno zilowerereni sweti, zomwe zingachepetse magetsi osasunthika chifukwa cha mikangano;
Njira 3: kapena mutha kupukuta sweti ndi chopukutira chonyowa kuti muchotse mosavuta magetsi osasunthika a sweti.
Ndi ma volts angati omwe ali ndi magetsi osasunthika mu juzi
Itha kupanga 1500 ~ 35000 volts yamagetsi osasunthika.
Njira zophatikizira zamagetsi za anthu ndi izi:
(1) Anthu amaimirira pampando kapena kupukuta khoma (kulekanitsa koyambirira kumachitika pamtunda wakunja wa zovala kapena zinthu zina zofananira, ndiyeno thupi la munthu limayimbidwa ndi induction.
(2) Anthu amayenda pazitetezo pansi monga makapeti opangidwa ndi zipangizo mkulu resistivity (kulekanitsa koyamba mlandu kumachitika pakati pa nsapato ndi pansi, ndiyeno, kwa nsapato conductive, thupi la munthu mlandu kutengerapo ndalama; chifukwa insulating nsapato, thupi la munthu mlandu ndi kupatsidwa ulemu).
(3) Magetsi osasunthika povula malaya. Uku ndi kukhudzana pakati pa chovala chakunja ndi chovala chamkati, ndipo thupi la munthu limalipiridwa kudzera mu kutumiza kapena kulowetsa.
(4) Madzi kapena ufa umatsanulidwa m’chidebe chimene munthu ali nacho (madziwo kapena ufawo umachotsa polar charge ndi kusiya kuchuluka kwa ndalama zotsutsana ndi thupi la munthu.
(5) Kulumikizana ndi zida zamoyo. Mwachitsanzo, mukamayesa ufa wopangidwa mwaluso kwambiri. Pakakhala njira yopititsira magetsi mosalekeza, kuthekera kwakukulu kwa thupi la munthu kumakhala kochepera 50kV chifukwa cha kutayikira ndi kutulutsa.
Ndi sweta yabwino
Ngati magetsi osasunthika a zovala zogulidwa kumene ali amphamvu kwambiri, ndichifukwa choti nsaluyo si yabwino. Mwachitsanzo, nsalu za ulusi wamankhwala zimakhala ndi magetsi amphamvu osasunthika, makamaka m'nyengo yozizira.
Zifukwa za magetsi osasunthika muzovala: ngati muvala zovala za thonje ndipo nyengo ili youma, anthu akakhala achangu, zovala ndi khungu zimasakanirana, ndipo maatomu pa zovala amataya ma elekitironi. Chifukwa chake, milandu yamkati ndi yakunja ya nyukiliya ya atomiki ndi yopanda malire, yomwe imapangitsa kuti ikhale yamagetsi. Komabe, chifukwa chinyezi (kuchuluka kwa nthunzi wa madzi) mozungulira ndi apamwamba kuposa m'nyengo yozizira, mtengo wopangidwa udzachotsedwa ndi nthunzi ya madzi mu nthawi kapena kukhudzana ndi dziko lapansi kudzera pakhungu, lomwe lidzatsogoleredwe kudziko lapansi.
