In the above accompanying drawing: 1, fuse group; 11, melt; 2, proving installation; 3, control device; 4, track.
Embodiment
Below in conjunction with embodiment shown in the drawings the present invention is further described.
Embodiment one: shown in accompanying drawing 1.
A kind of fuse automatic temperature measurement system is used for detecting automatically at the fuse life evaluating system temperature of each melt 11 in the fuse group 1, and it comprises proving installation 2, control device 3, is arranged on the proving installation 2 or the displacement transducer on the control device 3.
Proving installation 2 comprises temperature sensor, drives the executing mechanism that temperature sensor moves.Temperature sensor is contactless infrared thermal imaging temperature sensor.Executing mechanism comprises the stepper motor that is fixedly connected with temperature sensor and connects with signal with control device, the track 4 that matches with stepper motor, and track 4 is along the arragement direction setting of each melt 11.Displacement transducer is used for the monitor temperature sensing station.
Fuse automatic temperature measurement system has circulating measurement and fixed-point type is measured two kinds of working methods, and control device 3 is changed between two kinds of working methods according to the state of temperature control fuse automatic temperature measurement system of fuse group 1.Under the regular situation, this fuse automatic temperature measurement system is in circulating surveying work mode, and at this moment, control device 3 control step formula motors move along track 4, and temperature sensor is measured the temperature of each melt 11 one by one and the data back control device that records 3 is stored., the temperature of all melts 11 accomplishes the one-shot measurement circulation when all measuring.Through very first time interval, this very first time can be set in control device 3 at interval between adjacent twice measurement circulation.If the difference of the double measured value of the temperature of a certain melt 11 is during greater than first temperature difference, fuse automatic temperature measurement system is automatically converted to fixed-point type surveying work mode.The value of first temperature difference can be set in control device 3 according to actual conditions, for example is set at 10 ℃.
