Dispositivo de monitoreo de descarga parcial KGJL-OL
Introducción del producto
KGJF-OL type office on-line monitoring device is a real-time online monitoring device for substation GIS office, which is mainly suitable for office on-line monitoring, analysis and remote alarm of digital substations with voltage levels of 110kV and above, so as to realize the digitalization of substation maintenance.
Dispositivo de monitoreo de descarga parcial KGJL-OL
Caracteristicas de producto
1, alta sensibilidad. La sensibilidad de detección de partículas metálicas y descargas corporales potenciales flotantes puede alcanzar 5PC, Y la descarga parcial emitida por corona y fuga se puede detectar con precisión..
2, buena estabilidad. La selección de sensores de alta calidad., sensores de ruido externos y filtros especiales, el uso de tecnología de detección avanzada, con tecnología de procesamiento de software, para que la antiinterferencia sea fuerte, mejorar eficazmente la estabilidad del instrumento.
3, juicio preciso. The device continuously samples in real time, and only when the detected partial discharge signal meets the set “límite”, “densidad” y “credibility” al mismo tiempo, se considera anormal, y se mejora la precisión del juicio.
4, perfect data analysis function. The device has a perfect record to analyze the phenomenon of office release during GIS operation, determine the occurrence and development law of office release, and provide a basis for maintenance.
5, local and remote alarm. The device is equipped with local sound and light alarm function and remote software interface alarm function.
6, the device adopts RS485 communication, communication distance is long and reliable.
