Abstract
The utility model relates to a calibrating device of an infrared thermal imager. The calibrating device comprises a constant-temperature box, an adjusting support, a computer, a monitor, a radiation source, and a reference standard apparatus used for measuring the temperature of the radiation source. The infrared thermal imager to be calibrated is disposed on the adjusting support and is arranged in the constant-temperature box. The computer is connected with the infrared thermal imager and the monitor. The radiation source right faces the infrared thermal imager. Compared with a product in the prior art, the calibrating device has advantages of easy calibration and high calibrating precision.
Description
Technical field
The utility model relates to a kind of correcting device, especially relates to a kind of correcting device of thermal infrared imager.
Background technology
Thermal infrared imager can also be used to surveying the bad contact of electrical equipment, and overheated parts, in order to avoid cause serious short circuit and fire.
Statistics shows, the characteristics that have heating more than 25% in all electrical equipment common deficiencies are often because the loose contact initiation.For all equipment that can directly see, the infrared thermal imaging product can both be determined the hot hidden danger of all tie points.The part that can't directly see owing to shield for those, the situation on the parts outside then can being transmitted to according to its heat is found its hot hidden danger.The infrared thermal imaging product can also detect the imbalance of loop overload or threephase load at an easy rate.If do not adopt Infrared Thermography Technology, can only come discovering device loose contact and overheated by strip inspection and cleaning joint, efficient is low.Certainly, for the conventional test of isolating switch, conductor, bus and other parts, the infrared thermal imaging product can't replace.
But thermal infrared imager is owing to relate to more sensitive components, therefore need carry out regular detection calibration in order to guarantee that it can operate as normal to it, but lack at present a kind of convenient and swift, and the correcting device of standard comparatively.
The utility model content
The purpose of this utility model is exactly the correcting device that a kind of thermal infrared imager easily and efficiently is provided for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of correcting device of thermal infrared imager, comprise constant temperature oven, adjusting support, computing machine, monitor, radiation source and the reference standard that is used for the measuring radiation source temperature, thermal infrared imager to be calibrated is located to be regulated on the support, and place in the constant temperature oven, described computing machine connects thermal infrared imager and monitor, and described radiation source is over against the thermal infrared imager setting.
Described adjusting support is for being rotated the support with three movements.
Described radiation source is the cavate black matrix.
Described reference standard is platinum-resistance thermometer, thermocouple thermometer or radiation thermometer.
Compared with prior art, the utility model is by regulating the imageable target that support can the quick adjustment thermal infrared imager, shown by the collection image of high-resolution monitor to thermal infrared imager by computing machine, in conjunction with the temperature of radiator as a reference, thereby qualified when judging the sensitive components in the thermal infrared imager fast, calibration is standard fast and comparatively.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of correcting device of thermal infrared imager comprises constant temperature oven 1, regulates support 2, computing machine 3, monitor 4, radiation source 5 and reference standard.Thermal infrared imager 6 to be calibrated is located to be regulated on the support 2, and places and carry out environment temperature in the constant temperature oven 1 and regulate, and can be rotated and three movements owing to regulate support, imageable target that can the quick adjustment thermal infrared imager.Computing machine 3 connects thermal infrared imager 6 and monitor 4, gathers image-forming information, and shows by high-resolution monitor.Radiation source 5 can adopt the cavate black matrix, arranges over against thermal infrared imager 6, and demarcates its temperature by reference standard, as calibration reference.For the accuracy that guarantees to demarcate, reference standard can use platinum-resistance thermometer, thermocouple thermometer or radiation thermometer according to different situations.
