Abstract

APARELHO DE RETENÇÃO PARA UM ENROLAMENTO DE TRANSFORMADOR DE RESINA FUNDIDA. A presente invenção refere-se a um dispositivo de retenção para a fixação de um enrola-mento de transformador de resina fundida a um núcleo do transformador que possui um elemento de sustentação e um elemento receptor preso a um tirante de união. Ao fixar o elemento de sustentação ao elemento receptor preso ao tirante de união, um enrolamento de transformador de resina fundida pode ser fixado rígida e precisamente centrado com relação a um núcleo do transformador. Ao afixar o elemento receptor diretamente no tirante de união, garante-se a circulação na região inferior do enrolamento de transformador de resina fundida ou de um cilindro isolante também preso ao elemento de sustentação e, desse modo, as propriedades térmicas de um enrolamento de transformador de resina fundida produzido deste modo são aperfeiçoadas. Ademais, um projeto modular e, por-tanto, simples do transformador de resina fundida é possível devido à possibilidade de conectar o elemento receptor ao tirante de união por meio do elemento de sustentação.
