DR (Digital Radiograph) equipment and CR (X-ray Radiograph) board fixing device for GIS (Geographic Information System) equipment detection and detecting method

Abstract

The invention discloses DR (Digital Radiograph) equipment and a CR (X-ray Radiograph) board fixing device for GIS (Geographic Information System) equipment detection, and a detecting method. The method comprises the following steps of: mastering the positions of breaker contacts of the internal structures of the chambers of the GIS equipment; making positioning marks at the positions of shells corresponding to the breaker contacts; and fixing the DR equipment at the positions with the marks so as to accomplish the transillumination preparation work with fixed focus and fixed point. By utilizing the fixed focus and fixed point detecting method of the DR equipment, compared with the conventional method, the detection time and the working strength can be shortened, and the detection precision and the efficiency are improved. By utilizing the method and a specific fixing device provided by the invention, the number of transillumination personnel is greatly reduced, normally, 2-3 people are enough, and the accurate positioning can be realized rapidly, so that the transillumination preparation time is shortened to 5 minutes, and thus the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a DR equipment, a CR plate fixing device and a detection method for GIS equipment detection. Background technique [0002] Digital X-ray transillumination technology has been widely used in the medical field, and the most mature product is DR (Digital Radiography), which is currently more popular digital X-ray photography technology. With the continuous advancement of science and technology, relying on the continuous maturity of heat dissipation technology, the volume of the original hospital water-cooled DR board is improved to air-cooled, and the volume is greatly reduced. After being made into a portable DR imaging board, it can be widely used in industrial digital radiographic imaging. . Because it omits the darkroom processing of traditional film transillumination technology, the work efficiency is greatly improved. In addition, the use of DR radiography can greatly reduce the radiation dose absorbed by the staff, and the...

Problems solved by technology

However, in order to achieve sufficient stability, the supporting area occupied by the three legs of the tripod must be large enough, and in order to prevent instability, it must also use denser materials, which will encounter difficulties in handling and the narrowness of the site. ; And the use of hydraulic or mechanical lifting platform will also encounter the problem of difficult handling

The biggest problem is that the above auxiliary methods cannot guarantee the identity of multiple transilluminations of the same equipment. In this case, the positions of the negatives of the two transilluminations are different, and the focal lengths of the transillumination are different, and the obtained images will have a large gap. , it is impossible to conduct comparative analysis, thus affecting the analysis and judgment of the equipment
