Embodiment 1

[0017] Example 1, such as Figure 1-2 As shown, the electrical equipment 15 of the present embodiment is fixedly connected with the respective upper support plate 4 by the stay cords 7 in the angle adjustment assembly arranged up and down, and passes through the respective springs 6 and the lower support plate 5, and then passes through Through the angle adjustment assembly located below the angle adjustment assembly, four springs arranged in a rectangular array are arranged between the upper support plate 4 and the lower support plate 5, that is, four stay ropes 7 are evenly arranged on each upper support plate 4, The adjustment of the angle of the upper support plate 4 is realized by adjusting the retractable length of the stay cord 7 . In the initial state, the pull-down rope 7 does not move up and down, so that the springs 6 are bound to each other without inclination. The telescoping rod also includes a passage detection system, the passage detection system includes a ca...

Embodiment 2

[0023] Embodiment 2 is basically the same as Embodiment 1, except that the adjustment end 8 of the stay rope 7 in each upper support plate 4 is connected to the electric winch, and the inclination angle of each upper support plate 4 is controlled by the electric winch to realize mechanized operation. Compared with manually pulling the adjustment end 8, it is easier to control and saves time and effort.

[0024] The present invention controls the angle of the entire telescopic rod through the angle adjustment unit, and the telescopic unit 3 moves the angle adjustment unit and the test unit 1 forward, and finally realizes that the walking of the telescopic rod matches the passage formed between the electric equipment 15, so that the test unit 1 can Test the electrical equipment 15 whose installation location is relatively complicated and cannot be tested by common test equipment.

Abstract

The invention relates to a telescopic rod special for an electric power testing device, and belongs to the technical field of electric power overhaul equipment. The telescopic rod special for the electric power testing device comprises an installing rod used for installing a testing unit and a channel detection system; a group of angle adjusting assemblies connected in series through telescopic units are arranged between the installing rod and the testing unit, each angle adjusting assembly comprises a group of springs of which the two ends are fixedly connected with an upper supporting plateand a lower supporting plate and pulling ropes of which the upper ends penetrate through the corresponding lower supporting plate and the corresponding springs and are fixedly connected with the corresponding upper supporting plate, and an adjusting end is arranged at the lower end of each pulling rope; each telescopic unit is fixedly connected with the upper supporting plate and the lower supporting plate of the two adjacent angle adjusting assemblies; and the channel detection system comprises cameras arranged on the upper supporting plates and a display screen which is connected with the signal output ends of the cameras and arranged on the installing rod. Angle adjusting of the angle adjusting assemblies is achieved through the pulling ropes, overall conveying is achieved through the telescopic units, and finally the testing unit penetrates through a curved channel to make contact with electric power equipment for testing.

Description

technical field [0001] The invention belongs to the technical field of electric power maintenance equipment, and relates to a telescopic rod, in particular to a special telescopic rod for electric power testing equipment. Background technique [0002] At present, in power testing equipment, hand-held testing equipment is often difficult to reach high cable equipment, especially in GIS partial discharge testing, it is necessary to fix the test sensor on the surface of the GIS cabin, often requiring the staff to place the test sensor Press on the equipment shell, but due to the dense and compact arrangement of GIS cabins, it is difficult to measure in some narrow areas. , equipment and power grid bring great security risks. Therefore design a kind of device that can realize testing without climbing and become the problem urgently to be solved in this field. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention pr...
