contactori trifazati

Recommended Posts

Am un contactor trifazat Siemens de 16 A , vreau sa-l folosesc dar ... bobina e pe 110v. ce ar trebui sa fac sa-l aduc pe 220 fara sa rebobinez bobina? nu am spatie pt un numar mai mare de spire. Va multumesc!

Ce curent ia bobina alimentata la 110V?Daca cunosti aspectul , se poate rezolva prin inseriere cu o sarcina echivalenta

sau pune un autotransformator 220/110 micutz de puterea contactorului

Daca rebobinezi nr de spire va fi dublu si cu conductor de 2x mai saubtire ,asa ca va incapea spirele pt 220v. :supz:

"tiristor", are dreptate. E cea mai buna si sigura solutie. Nu trebe bobinat spira linga spira, e destul daca pui din 500 in 500 de spire cite o foita izolatoare suptire.

Eu nu izolez ci bobinez continu si cele industriale sunt facute la fel. :smt005

Da, insa cele industriale sunt bobinate cu conductori noi si cu calitatea izolatie foarte buna (am si eu un mosor de 0,3 mm si este un chin sa dai jos izolatia de pe conductor). In conditii de amator, cind nu cunosti producatorul conductorului cu care bobinezi, este binevenita acea foita izolatoare.

La cata munca este sa rebobinezi, mai bine iei unul la 220V din magazin sau din targ.

Cam jumatate de ora iti ia sa rebobinezi,din pacate bobine separate pt contactoare se vand mai rar,dar daca exista se poate cumpara pt cele romanesti dar cele din inport rebobineazale. :finga:
