Abstract

"SISTEMA E MéTODO PARA REDUZIR A TEMPERATURA DE UM REFRIGERANTE QUE ESCOA ATRAVéS DE UM SISTEMA DE REFRIGERAçãO DE TRANSFORMADOR DE POTêNCIA". Um sistema (27) para reduzir a temperatura de óleo refrigerante para um transformador de potência (12) inclui um trocador de calor (44) interposto no sistema de óleo refrigerante. O trocador de calor (44) depende da troca de líquido para líquido de calor a partir do óleo aquecido para um refrigerante que escoa através do trocador de calor. Numa realização, o refrigerante fornecido ao trocador de calor é obtido a partir de um resfriador de absorção (65). Energia térmica é fornecida ao resfriador (65) a partir de um dispositivo de armazenagem de calor (80). Numa realização específica, a fonte de armazenagem de calor (80) pode ser um dispositivo de material de mudança de fase. Num sistema de refrigeração preferido, um controlador programável (55) determina a ativação e operação do sistema. O controlador (55) pode detectar a temperatura de óleo refrigerante ou transformador para disparar a ativação. Numa realização preferida, o controlador (55) compara o histórico de temperatura corrente com um perfil de temperatura para prever maiores requisitos de refrigeração. Numa determinada realização, calor em excesso, fora de pico ou residual, proveniente do próprio transformador (12), é fornecido ao dispositivo de armazenagem de calor (80) ou ao trocador de calor de mudança de fase.
