3) can preestablish alert if according to request for utilization, realize monitoring in 24 hours.4) can be according to the characteristics of institute's measurement equipment temperature rise, set acquisition time at interval, change that also can temperature
Change, adjust acquisition time automatically at interval, realize full intellectualized measurement.5) collector has full intellectualized analyzing and diagnosing function, when section data of surveying sometime
Variation tendency occurs also can sending caution, prompting message when unusual, prompting operation maintenance personnel equipment
May occur to arouse attention unusually.
6) at each test point fixed installation point for measuring temperature contact, measurement data adopts the wireless biography of digital signal
Defeated, the measuring accuracy height, speed is fast, and real-time is good.7) can gather the temperature data of a plurality of test points simultaneously, and store automatically and record.
Be on the static contact of 49mm the utility model static contact wireless temperature measurement sensor to be installed at the breaker chamber interior diameter in the high-voltage board, but the temperature rise of on-line monitoring contact can more early pinpoint the problems, effectively avoid the generation of accident.
