It is difficult.Therefore, this project develops more connecting lever ultrasound examination bars, to solve these problems.
The patent document of application number CN201611008038 discloses a kind of GIS ultrasonic partial discharges reference test bar, including an insulation
The body of rod, the upper end for the body of rod that insulate, which is connected to one, can carry out the rotary shaft body of 360 degree of rotations and positioning, and in the front end of the rotary shaft body
Portion is equipped with ultrasonic probe, and the ultrasonic probe is fixedly mounted on insulation body of rod lower part by being connected under a test lead
Or the ultrasonic probe is a ultrasonic sensor on the receiver separately set；It has simple in structure, easy to use and reliable, saving
The features such as testing time improves working efficiency, reduces use cost, improve measuring accuracy.The structure is disadvantageous in that：Make
With simple hand-held, operation field is equipped with the Work tools such as insulating ladder, insulation bench, to complete the higher measuring point in position, but this
Kind of mode is time-consuming and laborious, and extra staff is needed to go to remove and help insulating ladder；It is visited in addition, installing ultrasonic wave at the top of insulating bar
Head, this mode solve the test problem of part eminence measuring point, but for the survey at the top of some narrow spaces and insulating cylinder
Point still can not be adjacent to detection, and can not solve the problems, such as that testing staff's effect of jitter gets collection of illustrative plates ready；In addition, for a high position
The detection set, by carrying the Work tools such as insulating ladder, insulation bench, more people assist common completion, the detection for narrow space to lead to
Crossing selection measuring point in its vicinity can just be detected.
Utility model content
