Li-contact tsa AC tsa low-voltage li sebelisoa haholo ho tima le ho tima phepelo ea motlakase ea lisebelisoa tsa motlakase, tse ka laolang lisebelisoa tsa motlakase li le hole, le ho qoba kotsi ea motho ha o tima le ho tima phepelo ea motlakase ea lisebelisoa. Khetho ea AC contactor ke ea bohlokoa haholo bakeng sa ts'ebetso e tloaelehileng ea lisebelisoa tsa motlakase le lithapo tsa motlakase.
1. Sebopeho le litekanyetso tsa AC contactor
Ka kakaretso, sesebelisoa sa AC contactor se hlokeha ho ba le sebopeho se kopanetsoeng, se bonolo ho se sebelisa, sesebelisoa se setle sa khoheli se fokang bakeng sa likhokahano tse tsamaeang le tse tsitsitseng, phello e ntle ea ho tima arc, zero flashover, le ho phahama ho honyenyane ha mocheso. Ho latela mokhoa oa ho tima arc, e arotsoe ka mofuta oa moea le mofuta oa vacuum, mme ho latela mokhoa oa ts'ebetso, e arotsoe ka mofuta oa motlakase, mofuta oa pneumatic le mofuta oa electromagnetic pneumatic.
Litekanyetso tse lekantsoeng tsa motlakase li arotsoe ka matla a phahameng le a tlase, 'me motlakase o tlase hangata ke 380V, 500V, 660V, 1140V, joalo-joalo.
Motlakase oa motlakase o arotsoe ka motlakase o fapaneng le oa hona joale o tobileng ho latela mofuta. Mekhahlelo ea hona joale e kenyelletsa rated ea ho sebetsa hona joale, ho lumellanoa ho futhumatsa hona joale, ho etsa hona joale le ho senya hona joale, ho lumellana ho futhumatsa hona joale ha likhokahano tse thusang le nako e khutšoanyane ea ho mamella hona joale ea contactor, joalo-joalo. maqhubu a sebetsang a tsamaisanang le mocheso oo ho lumellanoeng ka oona. Ka mohlala, bakeng sa CJ20-63, tekanyo ea ts'ebetso ea hona joale ea puisano e ka sehloohong e arotsoe ka 63A le 40A. 63 ka parameter ea mohlala e bua ka mocheso o lumellanoeng oa ho futhumatsa hona joale, o amanang le mohaho oa ho kenya letsoho oa khetla ea contactor, 'me motlakase o sebetsang o rated o amana le mojaro o khethiloeng hona joale, o amanang le boemo ba motlakase.
AC contactor coils arotsoe ka 36, 127, 220, 380V joalo-joalo ho ea ka gagamalo. Palo ea lipalo tsa contactor e arotsoe ka lipalo tse 2, 3, 4, 5 joalo-joalo. Ho na le lipara tse 'maloa tsa mabitso a thusang ho latela ka tloaelo a butsoeng le a tloaelehileng a koaloa, 'me a khethoa ho latela litlhoko tsa taolo.
Mekhahlelo e meng e kenyelletsa khokahano, linako tse robehileng, bophelo ba mochini, bophelo ba motlakase, maqhubu a phahameng a lumelletsoeng a ts'ebetso, bophara bo boholo bo lumelletsoeng ba wiring, litekanyo tsa kantle le boholo ba ho kenya, joalo-joalo.
