Abstract

Inventia se refera la un mecanism de comutare pentru dispozitive de protectie a transformatoarelor, a întrerupatoarelor cu ploturi pentru transformatoare sau a bobinelor de soc, care sunt racite cu lichid si sunt echipate cu vas de expansiune, mecanismul de comutare constînd, în esenta, dintr-o bara de ghidare care nu este feromagnetica, montata vertical într-o carcasa si care este prevazuta cu unul sau mai multe contacte magnetice de comanda. Scopul inventiei este acela de a crea un mecanism de comutare pentru dispozitive de protectie, prin care se extinde domeniul de utilizare a dispozitivului de protectie. în conformitate cu inventia, o clapeta articulata de retinere este legata la unul sau mai multi magneti permanenti plasabili între doua placi de aderenta feromagnetica. Aceste placi de aderenta limiteaza pozitia initiala, respectiv pe cea declansata a magnetului permanent. Clapeta articulata de retinere este executata ca pîrghie cotita, iar magnetul permanent este executat ca magnet inelar.The invention relates to a switching mechanism for transformer protection devices, transformer-type circuit-breakers or shock coils which are liquid-cooled and are equipped with an expansion vessel, the switching mechanism consisting essentially of a non- a guiding bar that is not ferromagnetic, mounted vertically in a housing and provided with one or more magnetic contact contacts. The purpose of the invention is to create a switching mechanism for protective devices which extends the scope of use of the protection device. According to the invention, an articulated retaining flap is connected to one or more permanent permanent magnets between two ferromagnetic bonding plates. These adherence boards limit the initial position, ie the trigger of the permanent magnet. The hinged clamping clamp is made as a crank lever and the permanent magnet is made as an annular magnet.
