" safeguard " device of ABB AB's development adopts quartz crystal surface acoustic wave original paper as responsive to temperature original paper, directly stick on tested point and form the oscillation circuit output frequency signal relevant with temperature, then adopt totally digitilized design treatment circuit to carry out monitor temperature.This device temperature measurement structure is loaded down with trivial details, and temperature-sensing element (device) directly sticks on tested point, effect and poor reliability.
The current path change that Japan power industry research centre uses a junction causes surrounding magnetic field to produce distortion, the change of employing magneto-optical sensor metering contact surrounding magnetic field judges the abnormal contact condition in bus connection and gas-insulated switch, this temperature measurement structure and temp measuring method require that sensor has enough sensitivity, and the distortion of field that current convergence causes can detect enough greatly by electric current, therefore functional reliability is lower.
Existing infrared thermography is widely used in electric system, but because high-tension switch cabinet inner structure is complicated, block mutually more between element, indirectly obtain temperature data device accuracy by infared spectrum can not meet the demands, artificial cognition can't be substituted to the Computer Recognition Technology level of infared spectrum, automaticity is lower, and the cost of infrared thermography is higher simultaneously.
Publication number is the patented technology of CN201210092, provide a kind of switch cabinet contact temperature boost on-line monitoring system, it is the temperature measuring equipment based on Radio Transmission Technology, temperature sensor is adopted directly to contact with contact and adopt wireless transmission method to obtain contact temperature, although well solve high_voltage isolation problem, but because of sensor and contact, cause that certain interference is existed to contact temperature field, so have impact on the accuracy of measurement to a certain extent.
Publication number is the high-tension switch cabinet infrared temperature measurement on-line device of patented technology based on wireless transmission of CN201207000, lacks historical storage, time interocclusal record and temperature collection function, thus comprehensively can not grasp status information when fault occurs.
