Abstract

Sistema de detección de fallos en el aislamiento de las espiras de devanados de máquinas eléctricas trifásicas con al menos uno de ellos conectado en triángulo, para motores y transformadores, de alta o baja tensión. Consiste en tres captadores de corriente (1), un dispositivo sumador de dichas corrientes (2) y un dispositivo de actuación dependiente del resultado de la suma de dichas corrientes (3), que podrá ser un dispositivo de medida de la corriente resultante o un dispositivo de desconexión con o sin umbral de actuación. Puede incorporar un sistema compensador de pequeños desequilibrios. Puede contener un único captador tipo transformador toroidal (4) que realice directamente la suma (6). Las corrientes de fase pueden obtenerse de estas dos formas, o mediante la medición mixta de alguna o algunas de las corrientes de fase y alguna o algunas de las corrientes de línea. De aplicación en el sector eléctrico.Fault detection system in the insulation of the winding turns of three-phase electrical machines with at least one of them connected in delta, for high or low voltage motors and transformers. It consists of three current sensors (1), an adding device for said currents (2) and an actuation device dependent on the result of the sum of said currents (3), which may be a device for measuring the resulting current or a disconnection device with or without actuation threshold. It can incorporate a compensating system for small imbalances. It can contain a single toroidal transformer-type sensor (4) that directly performs the sum (6). The phase currents can be obtained in these two ways, or through the mixed measurement of one or more of the phase currents and one or more of the line currents. Application in the electrical sector.
