HOLOGRAPHIC DETECTION DEVICE AND METHOD FOR GAS CONTENT IN GIS SWITCH

摘要

A holographic detection device for a gas content in a GIS switch comprises a laser and a data processing system. The laser comprises a laser transmitter (1) and a laser receiver (3). The laser transmitter (1) and the laser receiver (3) are fixed at a sampling port (4) of the GIS switch through a flange and are connected to the data processing system through optical cables. A holographic detection method for a gas content in a GIS switch comprises: transmitting a laser beam into a GIS switch; receiving a laser beam from the GIS switch; and calculating, according to the light intensity of the transmitted laser beam and the light intensity of the received laser beam, a content of hydrogen fluoride gas in the GIS switch. The laser beam passes through the inside of the GIS switch, so the detection result only has a small error and can reflect the real condition inside the GIS switch.
