Double-window temperature rise infrared collection and detection device for gas switch equipment

Abstract

The invention relates to a double-window temperature rise infrared collection and detection device for gas switch equipment. The double-window temperature rise infrared collection and detection deviceis mainly and technically characterized by comprising a germanium glass probe, a bismuth-doped glass sheet, a pyroelectric detection array, a fixing piece, an airtight flange and an aviation plug, the pyroelectric detection array is installed in the ring fixing piece, the bismuth-doped glass sheet and the germanium glass probe are located above the pyroelectric detection array and installed on the fixing piece, and the focal plane of the germanium glass probe is attached to the light receiving face of the pyroelectric detection array. A back plate of the pyroelectric detection array is provided with a power line and a signal feeder line and is led out from the airtight flange through an aviation plug; and the airtight flange fixes the germanium glass probe, the bismuth-doped glass sheet and the pyroelectric detection array at the opening of the shell of the gas switch equipment through fixing pieces. The device is reasonable in design, achieves the precise monitoring of the abnormal temperature rise of a key position in the device, is small in size, is large in field of view, and is high in sensitivity.

Description

technical field [0001] The invention belongs to the field of gas-insulated power equipment, and relates to monitoring the insulation state of gas-insulated power equipment, in particular to a double-window temperature-rise infrared collection and detection device for gas switchgear. Background technique [0002] In the process of manufacturing, assembling and transporting gas-insulated equipment, thermal defects such as high resistance or poor electrical connection will inevitably form, which will cause continuous or intermittent abnormal heating in the flow-through state, resulting in heat loss and heat loss of the equipment. Ageing. The abnormal heating inside the gas insulated equipment is an important cause of insulation deterioration, and it is also the external manifestation of insulation failure. Through the detection of abnormal heating, the detection and early warning of thermal defects and thermal faults in the gas switchgear can be realized. [0003] Thermal radi...
