Mu ma frequency converter, mabuleki othamanga amagalimoto kapena kuyimitsa kolondola, nthawi zambiri amagwiritsa ntchito mabuleki amagetsi ndi mabuleki osinthika.Pamagetsi oyendetsa mphamvu, torque ya braking yomwe imafunidwa ndi dongosolo ili pansi pa 20% ya ma torque ovotera agalimoto ndipo braking sikuyenda mwachangu, palibe chifukwa cholumikizira ma braking akunja, ndipo kutayika kwamkati kokha kwagalimoto kumatha. pangani malire a magetsi a mbali ya DC pansi pa mtengo wachitetezo chamagetsi.M'malo mwake, ndikofunikira kusankha chopinga cha braking kuti chiwononge gawo ili la mphamvu zosinthidwanso ndi mota.Kuti muzindikire kuphulika kwamagetsi, mbali ya DC ya inverter iyenera kukhala ndi dera lodziwira voteji kuti izindikire voteji ya capacitor kuti izindikire kuphulika kwa mphamvu.Braking resistorsamagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zamagetsi.
Pamene braking ndi kunja braking resistor, resistor kunja ayenera kuyamwa 80% ya mphamvu magetsi kusandulika ndi katundu mphamvu mphamvu, amene 20% akhoza kudyedwa kudzera galimoto mu mawonekedwe a dissipation kutentha, pa nthawi imeneyi mtengo. wa braking resistor amakhala ang'onoang'ono, kaya galimoto mobwerezabwereza decelerated, kusankhabraking resistoroveteredwa mphamvu ndi zosiyana.Kutsika kosabwerezabwereza, koletsa braking kwa nthawi yapakati (T-tS)> 600s.Kawirikawiri ntchito mosalekeza ntchito resistor, pamene intermittent braking, resistor chololeka mphamvu adzawonjezera ntchito kusankha olondola wa braking unit resistor akhoza kufupikitsa ufulu kuyimitsa nthawi ya katundu inertia lalikulu kukwaniritsa kuyimitsa mofulumira kapena kuyimitsa molondola;angakhalenso mu pokha katundu mphamvu ndi adatchithisira tikwaniritse regenerative ntchito.
Makasitomala ena 'electrolysis workshop multifunctional unit design' sanaganizire kuwonjezera inverterbraking resistor, chifukwa cha nthawi yayitali yoyimitsa yaulere komanso mtunda wautali wagalimoto yayikulu, yomwe imakhala ndi ngozi yobisika yopanga ndi kugwira ntchito;ndizovuta kuzindikira malo olondola a trolleys ndi ma trolleys a aluminiyamu, zomwe zimakhudza magwiridwe antchito.Pambuyo kukhazikitsa ma braking resistors, mavuto omwe ali pamwambawa amathetsedwa.Komabe, tisaiwale kuti, posankha braking resistor, osati kuganizira zofunika za aliyense wopanga inverter braking resistor kusankha, komanso malinga ndi zofuna za wosuta ulamuliro ndi ntchito malo osiyanasiyana, ayenera kudzera liwiro. , torque ndi miyeso ina, ndiyeno kuwerengera kusankha kolondola kwa braking resistor, kuti mukwaniritse zomwe wogwiritsa ntchito akufuna.
