HZ-DGA-900

Le Hertzinno HZ-DGA-900 est un système avancé d'analyse des gaz dissous (AGD) en ligne, conçu pour la surveillance continue de l'état des transformateurs de puissance. . En utilisant une approche combinée de spectroscopie photoacoustique (PAS) et spectroscopie photonique Il permet une analyse très sensible et précise des gaz de défaut. .

Le système présente une innovation indépendante dans la technologie PAS, utilisant un Source de lumière infrarouge MEMS et un conception à double chambre pour surmonter les limitations courantes des systèmes PAS traditionnels, telles que l'atténuation de la source lumineuse et le bruit mécanique des hacheurs . Cette architecture matérielle robuste garantit une stabilité de mesure à long terme et une fonctionnement sans entretien sans avoir besoin de consommables de gaz vecteur ou d'étalonnage .

From ultrasonic sound to visual inspection evidence.

HA3 series acoustic camera combines a high-density MEMS microphone array, beamforming algorithms and optical image overlay. The camera captures sound arrival differences, calculates the sound source direction and displays the result as an acoustic heatmap over the visual image.
HOW IT WORKS

01

Sound Capture
144 digital MEMS microphones capture audible and ultrasonic sound signals from the target area.

02

Beamforming
AI beamforming algorithms suppress background noise and focus on target sound sources.

03

Visual Overlay
Acoustic heatmaps are displayed over HD optical images for intuitive source localization.

04

Inspection Output
Engineers can capture images, videos, annotations and inspection records for maintenance reporting.
