Instalaciju elektri\u010dne opreme za mosne dizalice i polaganje \u017eica treba strogo provoditi u skladu s prilo\u017eenom elektri\u010dnom shemom, dijagramom o\u017ei\u010denja, op\u0107im dijagramom elektri\u010dne opreme i odgovaraju\u0107im specifikacijama.<\/p>\n\n\n\n<p><strong>Pripremni radovi prije ugradnje<\/strong><\/p>\n\n\n\n<p>Prije elektri\u010dne instalacije mosne dizalice potrebno je detaljno upoznati relevantne elektri\u010dne \u0161eme i tehni\u010dke uvjete, razumjeti interakciju i principe upravljanja svake komponente. Kako bismo brzo rije\u0161ili sve probleme koji mogu nastati tokom instalacije i testiranja. Prije ugradnje, svu elektri\u010dnu opremu i komponente treba o\u010distiti i pregledati. Sva elektri\u010dna oprema i komponente treba da budu bez kvarova, da rade fleksibilno i da ne bi trebalo da bude zaglavljivanja ili labavljenja. Model, specifikacije i redoslijed zatvaranja kontakata elektri\u010dne opreme i komponenti moraju biti u skladu sa crte\u017eima.<\/p>\n\n\n\n<p><strong>Motor<\/strong><\/p>\n\n\n\n<p>Prvo, izvr\u0161ite op\u0107i vizualni pregled okretanjem spojnice i promatranjem da li se rotor fleksibilno rotira. I izmjerite njegov izolacijski otpor megoommetrom. Ako je stator ve\u0107i od 1,5 megaoma, a rotor ve\u0107i od 0,8 megaoma, mo\u017ee se koristiti. U suprotnom, treba ga osu\u0161iti.
