Kufotokozera kwa Chipangizo Choteteza Kukwera

Chipangizo choteteza kugwedezeka kwa magetsi. Choteteza kugwedezeka kwa magetsi ndi chipangizo choteteza chomwe chimapangidwa kuti chiteteze zida zamagetsi kuti zisawonongeke ndi kugwedezeka kwa magetsi kosakhalitsa. Chimazindikira kukwera kwa magetsi kosazolowereka mu dongosolo ndipo chimasuntha mphamvu yochulukirapo mwachangu kupita ku waya wapansi, motero chimaletsa kuwonongeka kwa zida zodziwikiratu chifukwa cha kukwera kwa magetsi.

Njira Yogwirira Ntchito Yoteteza Chipangizo

Zoteteza ma surge zimagwira ntchito bwino kwambiri panthawi ya machitidwe abwinobwino, kuonetsetsa kuti dera likugwira ntchito bwino mosalekeza. Komabe, pamene magetsi akukwera pang'onopang'ono—monga omwe amayamba chifukwa cha magalimoto atsopano, kusinthana kwa katundu, kapena kukwera kwa mphezi—chotetezacho chimasintha nthawi yomweyo kupita ku njira yotsika kwambiri, ndikuyendetsa mphamvu zochulukirapo pansi ndikuteteza zida zodziwikiratu kuti zisawonongeke. Kukwerako kukachepa, chipangizocho chimabwereranso ku mphamvu yake yayikulu, ndikuyambiranso kukhala maso osalankhula ndi chisokonezo chamagetsi.

Zochitika Zofunikira pa Chipangizo Choteteza Chipangizo

Chitetezo cha mphezi: chitetezeni ku kukwera kwa mphepo komwe kumachitika chifukwa cha mphezi yolunjika kapena yoyambitsa.

Kusintha kwa gridi: kuletsa ma overvoltages omwe amayambitsidwa ndi ntchito zosinthira ma gridi, kusintha kwa capacitor, ndi zina zotero.

Chitetezo cha zida zamagetsi: Tetezani zipangizo zolondola monga makompyuta, zida zolumikizirana, ndi zida zapakhomo.

Machitidwe a mafakitale: onetsetsani kuti zipangizo zofunika monga ma PLC, ma inverter, ndi masensa zikugwira ntchito bwino.

Miyezo ndi Malamulo a Zipangizo Zoteteza Kuwonjezeka

Kukhazikitsa Chipangizo Choteteza Kuwonjezeka

• Mphamvu yamagetsi iyenera kudulidwa musanayike, ndipo kugwira ntchito kwamoyo n'koletsedwa kotheratu;
• Ndikofunikira kulumikiza fuse kapena circuit breaker motsatizana kumapeto kwa module;
• Chonde lumikizani motsatira chithunzi choyika pamene mukuyika, pomwe DC+ ndiye mzere wabwino, DC- ndiye mzere woipa, ndipo PE ndiye mzere wapansi. Musawalumikize molakwika. Mukamaliza kukhazikitsa, tsekani chosinthira cha circuit breaker (fuse) ndikuwona ngati ntchitoyo ili bwino;
• Mukamaliza kukhazikitsa, ikani gawolo molondola ndikuwona ngati gawolo likugwira ntchito bwino;
• Mukamagwiritsa ntchito gawoli, mawonekedwe a zenera lowonetsa zolakwika ayenera kuyang'aniridwa nthawi zonse. Ngati zenera lowonetsa zolakwika lili lofiira kapena malo olumikizirana akutali atulutsa chizindikiro cha alamu, zikutanthauza kuti gawolo lili ndi vuto ndipo liyenera kukonzedwa kapena kusinthidwa pakapita nthawi;
