Classification: CPC G | IPC G

Claim 0:
1. An optical detection system, for detecting a decomposition product on a high-voltage device, comprising:
a measurement gas chamber applicable to be mounted on the high-voltage device and for communicating with a gas chamber of the high-voltage device; and
a measurement host,
wherein 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; and
the collimator is configured 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,
wherein the measurement host comprises a laser device, a switching module, and an infrared detector;
the switching module is connected to the laser device and the infrared detector respectively; and
the switching module is configured for transmitting a laser signal from the laser device to the collimator, and transmitting the reflected laser from the collimator to the infrared detector.
