Abstract

DISPOSITIVO DE CONEXãO DESTACáVEL PARA SELETOR DE DERIVAçãO A VáCUO PARA TRANSFORMADORES ELéTRICOS. Um dispositivo de conexão destacável para seletores de derivação a vácuo (10) para transformadores elétricos, do tipo apropriado para constituir um contato fixo (12), que é posicionado sobre um corpo em forma de haste (11) de um seletor de derivação (10) associado com dispositivos de servo comando (13) atuando sobre suportes (15) contendo contatos móveis ajustados a uma tensão de referência e deslizando sobre contatos fixos (12); especialmente, o dispositivo de conexão destacável compreende um pino (23) sobre o qual é pré-montado um elemento elástico mantido em posição por uma cavilha (24) disposta ortogonalmente às paredes do pino (23). O pino (23), inserido no interior de uma bucha conformada (29) que é inserida, por sua vez, em uma respectiva abertura do corpo em forma de haste (11) do seletor de derivação (10) é pressionado além da espessura do corpo em forma de haste (11) e girado em qualquer direção, de tal maneira a dispor a cavilha (24) no interior de uma sede (39) prevista sobre uma superficie da bucha (29).HIGH CONNECTION DEVICE FOR VACUUM DERIVATIVE SELECTOR FOR ELECTRICAL TRANSFORMERS. A detachable connection device for vacuum tap selectors (10) for electrical transformers, of the type suitable for constituting a fixed contact (12), which is positioned on a rod-shaped body (11) of a tap selector (10) ) associated with servo drive devices (13) acting on brackets (15) containing movable contacts adjusted to a reference voltage and sliding over fixed contacts (12); especially, the detachable connecting device comprises a pin (23) on which an elastic element held in position by a pin (24) orthogonally disposed to the walls of the pin (23) is pre-assembled. The pin (23) inserted into a shaped bushing (29) which is in turn inserted into a respective opening of the rod-shaped body (11) of the tap selector (10) is pressed beyond the thickness of the rod-shaped body (11) and rotated in any direction such that the pin (24) is arranged within a seat (39) provided on a surface of the bushing (29).
