Abstract
Disclosed is an optical detection system for detecting a decomposition product of a high-voltage device, including: a measurement gas chamber and a measurement host. The measurement gas chamber is disposed on the high-voltage device and is in communication with a gas chamber of the high-voltage device, a collimator and a reflector are disposed on two sides of the measurement gas chamber respectively, and the measurement host is connected to the collimator. The collimator is used for emitting measurement laser to the measurement gas chamber according to a laser signal sent by the measurement host, and receiving reflected laser from the reflector and transmitting the reflected laser to the measurement host. In the present invention, data collection and backhaul between a measurement host and a measurement gas chamber are implemented through a laser signal, thus avoiding electromagnetic interference and improving the safety of measurement for a high-voltage device.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
