specific Embodiment 1

[0035] Such as Figure 1-7As shown in the figure, the device for accurate and rapid measurement and calculation of UHV substation conductors includes a main detection ring 1 and a display terminal 12. The main detection ring 1 is symmetrically divided into a first detection ring 2 and a second detection ring 3 along the horizontal center line. Both sides of the bottom surface of the first detection ring 2 and the top surface of the second detection ring 3 are provided with a storage tank 8, and the inside of the storage tank 8 is provided with a biaxial hydraulic cylinder 4, and the two sides of the biaxial hydraulic cylinder 4 are fixedly provided with a connecting frame 5, and the connecting frame 5. One end away from the double-axis hydraulic cylinder 4 is fixed to the side of the storage tank 8. The connecting frame 5 supports the inside of the storage tank 8 on the surface of the double-axis hydraulic cylinder 4. The movable ends on both sides of the double-axis hydraulic ...

specific Embodiment 2

[0039] Such as Figure 7 As shown, the accurate and fast method for measuring and calculating the conductors of UHV substation projects, the calculation method for detecting the main ring 1 is as follows:

[0040] Sp1: Determine the environment, determine the position of the uninstalled UHV wire to be detected, and perform clamping of the clamping devices 14 on both sides of the detection main ring 1 according to the detected length and position of the UHV wire;

[0041] Sp2: installation preparation, clamp the clamping device 14 at the position where the two ends of the length of the UHV wire to be tested are located, the end of the UHV wire passes through the detection main ring 1, and the detection main ring 1 is placed at one end of the UHV wire, Remove the display terminal 12 from the bottom of the handle 7, and the preparatory work is completed;

[0042] Sp3: detection, the biaxial motor 1303 of the connection device 13 rotates, one end of the connection steel wire 1304...

Abstract

The invention provides a method and a device for accurately and quickly measuring and calculating an extra-high voltage power transformation project wire, and relates to the technical field of extra-high voltage power transformation project wire detection. The device comprises a detection main ring and a display terminal, the detection main ring is symmetrically divided into a first detection ring and a second detection ring along a horizontal center line, and the external bottom surface of the second detection ring is in bolted connection with a supporting base; a handheld handle is welded to the bottom of the supporting base, and a display terminal is arranged at the bottom of the handheld handle. A connecting device is arranged in the second detection ring; the connecting device comprises a double-shaft motor and a connecting steel wire, a clamping device is fixedly arranged at the end of the connecting steel wire, a displacement sensor is arranged in the detection main ring, and the detection main ring and the surface of the extra-high-voltage wire are detected in a penetrating mode. The displacement sensor is used for positioning and measuring the position of the detection main ring; and the double-shaft motor winds the connecting steel wire to drive the detection main ring to move. The detection main ring is held by the handheld handle for fixed-point detection, so that the surface detection of the extra-high voltage wire is more thorough, the portability is higher, and the integration of automation and manual operation is realized.
