Title:
OPTICAL DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/082838
Kind Code:
A1
Abstract:
An optical detection system for detecting decomposition products of a high-voltage device, comprising: a measurement gas chamber (2) and a measurement main computer (1); the measurement gas chamber (2) is arranged on the high-voltage device and is in communication with a gas chamber of the high-voltage device; a collimator (21) and a reflection mirror (22) are respectively provided at two sides of the measurement gas chamber (2), and the measurement main computer (1) is connected to the collimator (21); and the collimator (21) is configured to emit a measurement laser to the measurement gas chamber (2) according to a laser signal emitted by the measurement main computer (1), and receive a reflected laser from the reflection mirror (22) and transmit the reflected laser to the measurement main computer (1). The measurement main computer (1) and the measurement gas chamber (2) achieve data acquisition and back transmission by means of the laser signal, achieve radio signal transmission, avoid electromagnetic interference, and improve the safety of measurement of a high-voltage device.
