Momwe Zowumitsira Manja Zimagwirira Ntchito

Mfundo yogwirira ntchito ya chowumitsira pamanja nthawi zambiri ndikuti sensa imazindikira chizindikiro (dzanja), ndipo chizindikirochi chimagwiritsidwa ntchito kuwongolera kutsegulidwa kwa relay yotenthetsera ndi kuwulutsa kozungulira, ndikuwotcha ndi kuwomba kumayambika. Chizindikiro chodziwika ndi sensa chikasowa, kukhudzana kumatulutsidwa, dera lotenthetsera ndi kuwomba kozungulira kumachotsedwa, ndipo kutentha ndi kuwomba kumayimitsidwa.
Chipangizo chotenthetsera chili ndi chipangizo chotenthetsera, PTC, ndi waya wotenthetsera wamagetsi.
1. Palibe chipangizo chotenthetsera, monga momwe dzinalo likusonyezera, palibe chipangizo chotenthetsera
Ndiwoyenera malo omwe ali ndi kutentha kwambiri komanso malo omwe zowumitsa zimagwiritsidwa ntchito pafupipafupi,
Mwachitsanzo: kulongedza zinthu zamasamba zofulumira-zozizira komanso zofulumira-zozizira
2. Kutentha kwa PTC
Kutentha kwa PTC thermistor, chifukwa ndi kusintha kwa kutentha kozungulira, mphamvu ya kutentha kwa PTC imasinthanso moyenera. M'nyengo yozizira, mphamvu yotenthetsera ya PTC imachuluka, ndipo kutentha kwa mpweya wotenthedwa ndi chowumitsira kumawonjezekanso, zomwe zimateteza{1}}kupulumutsa mphamvu komanso kusawononga chilengedwe.

-zoumitsira m'manja mwachangu zimagwiritsa ntchito mawaya otenthetsera magetsi, CPU ndi zowongolera kutentha kuti ziwonjezeke mwachangu komanso mosalekeza. Ngakhale mphepo ikathamanga kwambiri mpaka 100 m/s, chowumitsira pamanja chimatha kutulutsa mpweya wotentha nthawi zonse.
Nthawi zambiri, zowumitsira m'manja zomwe zimagwiritsa ntchito mphepo ngati zazikulu komanso zotenthetsera ngati chothandizira zimakhala ndi phokoso lalikulu, pomwe zowumitsira m'manja zomwe zimagwiritsa ntchito kutentha monga chachikulu zimakhala ndi phokoso lochepa. Mabizinesi amatha kusankha malinga ndi momwe alili.
