Makhalidwe ndi Ntchito za Zingwe Zotetezedwa

Chingwe chotetezedwa chimatanthauza chingwe chokhala ndi mawonekedwe oteteza magetsi omwe amapangidwa ndi waya wachitsulo kapena tepi yachitsulo. Chingwe chowongolera chitetezo cha KVVP ndi choyenera chingwe chovomerezeka cha 450/750V ndi pansi pa ulamuliro, kuyang'anira mzere wolumikizira dera, makamaka kuti apewe kusokoneza kwa mafunde amagetsi, choyenera ma transformers ndi makina ndi zida zina zomwe ziyenera kutchinga chizindikiro cha magetsi, chitetezo cha chingwe chimatanthauza kapangidwe ka netiweki ya chingwe kumapeto kwa waya wolukidwa, magwero akunja amagetsi ndi magwero amagetsi amatha kulowa pansi nthawi yomweyo popanda kukhudza chingwe chamkati.
Ntchito ya chingwe choteteza.
Kawirikawiri imagwiritsidwa ntchito pa mizere yokhala ndi chizindikiro cha pulse cha data cha pafupipafupi komanso chotsika, monga wailesi yakanema ya digito, kusintha kwa ma frequency kukhala ma motor lines, ma analog input lines, ndi ma transmission lines ena amphamvu, monga ma cable otetezedwa ndi kompyuta. Bola chingwecho chili ndi shielding layer, chimatchedwa shielding cable, ndipo chingwe cha power engineering ndi chingwe chogwirira ntchito zitha kukhala ndi shielding layer. Ma cable apakompyuta ndi zida nthawi zambiri amatetezedwa kuti apewe kukhudzidwa ndi ma electromagnetic wave signals akunja, ndipo ma cable otetezedwa ndi oyenera ma motor connection cables, makamaka ma variable frequency gavernars ndi servo motor drives. Oyenera ma polyurethane wire protectors onse ndi copper cable insulation, oyenera ma cable tow chains, makamaka pa mapulogalamu ovuta kwambiri komanso malo oziziritsira ndi mafuta.
Pamene mbali imodzi ya chishango yakhazikika, pamakhala mphamvu yamagetsi pakati pa chishango ndi mbali yosakhazikika, ndipo mphamvu yamagetsi yokhazikika imakhala yogwirizana ndi kutalika kwa chingwe, koma chishangocho sichili ndi mphamvu yamagetsi yofanana ndi kutalika kwa chingwe. Kukhazikika kwa magetsi kwa single-terminal kumagwiritsa ntchito mphamvu yamagetsi yoletsa kusiyana kuti achotse zizindikiro zosokoneza. Njira iyi yokhazikika ndi yoyenera mizere yayifupi, ndipo mphamvu yamagetsi yokhazikika yofanana ndi kutalika kwa chingwe singakhale yokwera kuposa mphamvu yogwirira ntchito. Kupezeka kwa mphamvu yamagetsi yokhazikika.
