Chiyambi
Pamenekakang'ono switchIkayatsidwa kapena kuzimitsidwa, "kanthu kakang'ono kamagetsi" kamawonekera nthawi zambiri pakati pa zolumikizirana. Uwu ndi mzere. Ngakhale kuti ndi wochepa, ungakhudze nthawi yogwira ntchito ya switch komanso chitetezo cha zida. Kumvetsetsa zomwe zimayambitsa, zoopsa za mzere, ndi njira zothanirana bwino ndikofunikira kwambiri pakukweza kudalirika kwa makina ang'onoang'ono. masiwichi.
Mbadwo wa Arcs: "Small Spark" Pamene Mphamvu Yasokonekera
Pamene ma contacts a micro Ngati magetsi atsegulidwa kapena kutsekedwa, kusintha kwadzidzidzi kwa mphamvu yamagetsi kungayambitse kuti mpweya pakati pa zolumikizira ukhale wa ionized, zomwe zimapangitsa kuti arc ikhale ngati mphezi. Zili ngati mphezi pa tsiku lamvula, koma pang'ono kwambiri. Izi zimaonekera kwambiri ngati magetsi akugwiritsidwa ntchito kuwongolera zida zokhala ndi katundu, monga ma mota kapena mababu amagetsi. Mphamvu yamagetsi ikakula komanso mphamvu yamagetsi ikakwera, ndiye kuti arc imachitika nthawi zambiri. Kutulutsa kwamphamvu komwe kumachitika nthawi zina mukakanikiza switch yapakhomo ndi chitsanzo cha arc iyi.
Zoopsa za Arcs: "Silent Killer" Yowononga Ma Switch
Ma arc ndi otentha kwambiri ndipo pang'onopang'ono amatha kuwononga pamwamba pa ma contact, zomwe zimapangitsa kuti asagwirizane. Pakapita nthawi, izi zingayambitse kukhudzana koyipa, komwe switch siyankha ikakanikiza kapena chizindikiro chimakhala chosinthasintha. Mwachitsanzo, mabatani a mbewa akasiya kugwira ntchito atagwiritsidwa ntchito kwa nthawi yayitali, nthawi zambiri zimakhala chifukwa cha ma contact omwe amawonongeka ndi ma arc. Pazochitika zazikulu, ma arc angayambitse ma contact kuti amamatirane, zomwe zimapangitsa kuti switch isazime ndikuyika pachiwopsezo chogwiritsa ntchito zida nthawi zonse, makamaka m'makina amafakitale ndi magalimoto, komwe zolakwika zotere zingayambitse ngozi zachitetezo.
Njira Zoletsera: Kuwonjezera "Chishango" ku Switch
Pofuna kuthana ndi ma arc, makampaniwa apanga njira zingapo zothandiza. Ma RC buffer circuits, opangidwa ndi ma resistors ndi ma capacitor, amagwira ntchito ngati "buffer pad" potengera mphamvu zomwe zimapangidwa ndi ma arc, monga momwe zimakhalira ndi speed bump pakusintha kwa mphamvu yamagetsi, kuchepetsa mphamvu ya ma sparks. Ma Varistors amagwira ntchito ngati "alonda a zipata," osagwira ntchito pansi pa mphamvu yamagetsi yanthawi zonse koma nthawi yomweyo arc ikayambitsa kukwera kwadzidzidzi kwamagetsi, kutembenuza magetsi ochulukirapo ndikuteteza ma contacts. Ma Solid-state relay, omwe amagwiritsa ntchito zida zamagetsi kuwongolera mphamvu yamagetsi popanda ma mechanical contacts, kwenikweni amachotsa kuthekera kwa ma arcs ndipo amagwiritsidwa ntchito kwambiri pazida zamankhwala ndi zida zolondola kwambiri.
Mapeto
Njira zochepetsera izi zimapangitsa kuti zinthu zing'onozing'ono Ma switch olimba komanso odalirika. Kuchepetsa mphamvu ya ma arc kungachepetse mwayi wa zolakwika ndikuwonjezera nthawi ya moyo wa zida zapakhomo ndi zida zamafakitale. Ndi kupita patsogolo kwaukadaulo, "mphamvu yowononga" ya ma arc ikuchepa nthawi zonse, zomwe zimapangitsa kuti ma micro-microphones ang'onoang'ono azitha kugwira ntchito. ma switch kuti agwire ntchito bwino nthawi zambiri ndikuteteza mwakachetechete magwiridwe antchito a zida.
