Abstract

Patente de Invenção: <B>''MáQUINA ELéTRICA REFRIGERADA A GáS''<D>. Em uma máquina elétrica refrigerada a ar com refrigeração reversível em circuito de refrigeração fechado, uma disposição de refrigeração é disposta em um poço de fundamento (10) abaixo da máquina e construída modularmente. Ela consiste em um grande número de refrigeradores (11) que são situados independentemente uns dos outros no poço do fundamento (10) e separados uns dos outros por paredes de separação que correm perpendicularmente ao sentido longitudinal da máquina. As aberturas de saída dps refrigeradores (11) estão em livre comunicação com as câmaras de gás frio (14, 16) entre a crcaça da máquina (1) e corpo de chapas do estator (2). As aberturas de entrada dos refrigeradores (11) estão em livre comunicação com um espaço de descarga dos dois ventiladores (12) nos lados frontais da máquina. Este modelo possibilita, além de uma condução de gás de refrigeração otimizada, uma rápida troca e/ou desconexão de um refrigerador.
