Abstract

Mejoras en disposiciones de transferencia térmica para protectores contra elevación súbita de tensión, caracterizadas por comprender; una carcasa, eléctricamente aisladas y definido por una configuración de doble radio, conformandose el primer radio al radio de un varistor de óxido de zinc dentro de la carcasa y procurando el segundo radio un espacio de transferencia de gas; y medios de transferencia de calor entre el varistor y una pared de la carcasa para conducir calor alejándolo del varistor hacia la pared de la carcasa.
