Problems solved by technology

[0002] At present, in power testing, it is often difficult for hand-held testing equipment to reach high electrical equipment. Especially in GIS partial discharge testing, it is necessary to fix the test sensor on the surface of the GIS cabin, and often require the staff to press the test sensor on the equipment. However, due to the dense and compact arrangement of the GIS cabins, it is difficult to measure in some areas with small spaces. This requires the staff to adopt methods such as climbing, climbing, and drilling. Not only the measurement efficiency is low, but also the human body, equipment and power grid pose a great safety hazard

Embodiment 1

[0019] Example 1, such as Figure 1-2 As shown, the upper end of the installation rod 2 is provided with a group of angle adjustment assemblies connected end to end in sequence, and each angle adjustment assembly includes four stay ropes 6 arranged at the four corners of the upper support plate 4, and the upper support is realized through the adjustment of the stay rope 6 The adjustment of each angle of the plate 4; the upper support plate 4 of the adjacent two angle adjustment components is connected with the lower support plate 5, the upper end of the pull rope 6 is fixedly connected with the corresponding upper support plate 4, and the upper support plate 4 is upper and lower support plate 5 The via holes of the stay cord 6 are provided on the top, and the passage of the stay cord 6 is formed in combination with the cavity of the spring 3. The via holes on the upper support plate 4 are convenient for the stay cord 6 of the angle adjustment assembly above it to pass through. ...

Embodiment 2

[0024] Embodiment 2 is basically the same as Embodiment 1, as Figure 3-4 As shown, the difference is that the installation rod 2 is connected with the lowermost angle adjustment assembly by means of two telescopic rods 8, the fixed end of the telescopic rod 8 is threadedly connected with the installation rod 2, and the telescopic ends of the two telescopic rods 8 The two ends of the lower support plate 5 of the lowermost angle adjustment assembly are hinged. When it is necessary to test the electrical equipment 12 above the building, by adjusting the different elongation lengths of the two telescopic rods 8, all angle adjustment assemblies When the tilt occurs, the angle adjustment components are tilted above the building, which is convenient for the staff to adjust the angle of each angle adjustment component according to the passage formed by the electric equipment 12 so that the measuring unit 1 can walk to the electric equipment 12 under test.

Abstract

The invention relates to a telescopic device for electric power test equipment, and belongs to the technical field of power maintenance equipment. The telescopic device comprises a mounting rod for mounting a measuring unit, the mounting rod is provided with a set of angle adjusting components connected end to end, the angle adjusting component comprises a set of springs, an upper support plate and a lower support plate are respectively arranged at the two ends of the spring, and a pull cord sequentially passes through the lower support plate and the spring and the upper support plate, and themeasuring unit is connected to the upper support plate of the topmost angle adjusting component by means of the connecting member, the telescopic device further comprises a distance monitoring systemof the measuring unit. The upper support plate is tilted by the pulling rope to make an angle change of the upper support plate to adapt to various channels, thereby realizing effective measurement of the power device by the measuring unit.

Description

technical field [0001] The invention belongs to the technical field of electric power maintenance equipment, and relates to a telescopic device, in particular to a telescopic device for electric power testing equipment. Background technique [0002] At present, in power testing, hand-held testing equipment is often difficult to reach high electrical 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 press the test sensor on the equipment However, due to the dense and compact arrangement of the GIS cabins, it is difficult to measure in some areas with small spaces. This requires the staff to adopt methods such as climbing, climbing, and drilling. Not only the measurement efficiency is low, but also the human body, equipment and power grid pose a great security risk. Therefore design a kind of device that can realize testing without climbing and become the problem urgentl...
