Abstract
<B>"ESTAçãO DE TRANSMISSãO DE CHAVE INTERRUPTORA"<D> A presente invenção se refere a uma estação de transmissão de chave interruptora compreendendo pelo menos uma chave interruptora de transmissão e pelo menos uma máquina elétrica de rotação para alta voltagem. A referida máquina compreende pelo menos um enrolamento incluindo pelo menos um condutor elétrico. O condutor possui um sistema de isolamento compreendendo um isolamento formado por um material de isolamento sólido e, interiormente ao isolamento, uma camada interna possuindo uma condutividade elétrica a qual é mais baixa do que a condutividade do condutor elétrico, mas suficiente para causar à camada interna operar para equalização do potencial e, em concordância, a equalização como concerne ao campo elétrico exteriormente à camada interna. O sistema de isolamento compreende, exteriormente ao isolamento, uma camada externa a qual possui uma condutividade elétrica a qual é mais alta do que a do isolamento para fazer a camada externa ser capaz, por conexão à terra ou de outro modo a um relativamente baixo potencial, de operação para equalizar potencial, e de substancialmente englobar o campo elétrico, aparecendo como uma conseq³ência do referido condutor elétrico, interiormente à camada externa. Este projeto de condutor garante a conexão direta do enrolamento da máquina elétrica de rotação a uma rede de força de voltagem.<B> "SWITCH KEY TRANSMISSION STATION" <D> The present invention relates to a key switch transmission station comprising at least one transmission switch key and at least one high voltage rotating electrical machine. Said machine comprises at least one winding including at least one electrical conductor. The conductor has an insulation system comprising insulation formed by a solid insulation material and, inside the insulation, an inner layer having an electrical conductivity which is lower than the conductivity of the electric conductor, but sufficient to cause the inner layer operate to equalize the potential and, accordingly, equalize as it concerns the electric field outside the inner layer. The insulation system comprises, outside the insulation, an outer layer which has an electrical conductivity which is higher than that of the insulation to make the outer layer capable, by grounding or otherwise at a relatively low potential , of operation to equalize potential, and to substantially encompass the electric field, appearing as a consequence of the referred electric conductor, internally to the external layer. This conductor design guarantees the direct connection of the winding of the electrical machine of rotation to a network of voltage power.
