Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic measurement, in particular to a gas-insulated metal-enclosed transmission line measuring device. Background Art

[0002] The full name of GIL is Gas Insulated Transmission Lines, and its Chinese name is Gas Insulated Metal Enclosed Transmission Line Transmission System. Its transmission line includes a casing, and a transmission conductor for transmitting current is arranged inside the casing. The casing is also provided with an insulating gas for achieving gas insulation between the transmission conductor and the casing. The casing is connected to the ground for grounding. GIL uses transmission conductors to transmit current, which greatly improves the current transmission capacity of the transmission line.

However, in this measurement method, when a certain section of the transmission line is taken as the center of the circle, it is difficult for the thrust direction of the experimental cart to always maintain the same tangent angle, resulting in insufficient accuracy in the measurement of the electromagnetic environment of the transmission line.

[0069] When it is necessary to adjust and change the distance between the vertical plate 3 and the electromagnetic measuring instrument 11, the motor 18 is started first. The motor 18 starts to drive the gear 19 to rotate, and the gear 19 rotates and engages with the rack 20, so that the L-shaped plate 15 moves inside the long strip groove 16. The L-shaped plate 15 moves inside the long strip groove 16 and drives the round rod 17 to move. The round rod 17 moves and drives the vertical plate 3 to move inside the slide groove 2.

At the same time, in conjunction with the scale plate 14, the electromagnetic quantity of the gas-insulated metal-enclosed transmission line at different distances between the electromagnetic measuring instrument 11 and the utility pole can be measured, thereby obtaining the electromagnetic quantity at multiple distances, and finally comparing the electromagnetic quantities, thereby further enhancing the accuracy of the device measurement.

[0070] In an optional embodiment of the present utility model, a semicircular ring 21 is fixedly mounted on one end of the steering rod 4;

[0078] In an optional embodiment of the present utility model, universal wheels 24 are evenly installed at the top corners of the bottom surface of the base 1;

[0079] A handrail 25 is fixedly mounted on one side of the base 1 .

[0080] In an optional embodiment of the present invention, the handrail 25 is a U-shaped structure.

[0081] In this embodiment, four universal wheels 24 are fixedly mounted on the bottom surface of the base 1. The universal wheel refers to a freely rotatable wheel fixed to the chassis of the vehicle. Its spokes and rim are not fixed together, but use specially designed bearings, turntables and transmission mechanisms to rotate freely and change direction, so as to realize the vehicle's translation, oblique movement and turning movements; the free rotation and direction-changeable characteristics of the universal wheel can help the vehicle complete the steering action more quickly and smoothly, and improve the vehicle's controllability and safety; the universal wheel has less friction resistance during driving, which can reduce the resistance and friction of the vehicle during driving, and improve the efficiency and speed of the vehicle; the universal wheel can realize the multi-directional movement of the vehicle, and can even drive obliquely to avoid road obstacles, thereby improving the vehicle's ability to pass bumps and passability;

[0082] A handrail 25 is fixedly mounted on the side of the base 1 . The handrail 25 is a U-shaped structure, which facilitates the movement of the base 1 .

[0083] Working principle: when electromagnetic measurement is required, first push the handrail 25 and then cooperate with the universal wheel 24 to drive the base 1 to move. When the base 1 moves to a position where the electric pole is located between the two clamping rings 10, the rotating wheel 22 is rotated at this time. The rotation of the rotating wheel 22 drives the threaded rod 8 to rotate. Since the threads on the surface of the threaded rod 8 are reverse threads with the rotating wheel 22 as the center, when the rotating wheel 22 drives the threaded rod 8 to rotate, the two displacement plates 9 threadedly connected on its surface move toward each other inside the strip groove 23. The two displacement plates 9 move toward each other inside the strip groove 23 to clamp and limit the electric pole. Then start the electromagnetic measuring instrument 11, and then push the handrail 25 to make the base 1 make a circular motion around the electric pole, so that during measurement, the distance between the electromagnetic measuring instrument 11 and the electric pole is always kept equal, thereby improving the accuracy of measuring electromagnetic quantities within an equidistant range under gas-insulated metal-enclosed transmission lines. When it is necessary to adjust and change the distance between the vertical plate 3 and the electromagnetic measuring instrument 11, the motor 18 is started first. The motor 18 starts to drive the gear 19 to rotate, and the gear 19 rotates and engages with the rack 20, so that the L-shaped plate 15 moves inside the long strip groove 16. The L-shaped plate 15 moves inside the long strip groove 16 and drives the round rod 17 to move. The round rod 17 moves and drives the vertical plate 3 to move inside the slide groove 2. The vertical plate 3 moves inside the slide groove 2 and drives the horizontal strip plate 6 to move. The horizontal strip plate 6 moves and finally drives the two clamping rings to move. When the vertical plate 3 is inside the slide groove 2, the horizontal strip plate 6 moves. When the part moves to the appropriate position, the motor 18 is turned off, and then the distance between the electromagnetic measuring instrument 11 and the vertical plate 3 can be known by comparing with the scale plate 14. Through the cooperation of the above structure, the distance between the vertical plate 3 and the electromagnetic measuring instrument 11 can be adjusted. At the same time, in conjunction with the scale plate 14, the electromagnetic quantity of the gas-insulated metal-enclosed transmission line at different distances between the electromagnetic measuring instrument 11 and the utility pole can be measured, thereby obtaining the electromagnetic quantity at multiple distances, and finally comparing the electromagnetic quantities, thereby further enhancing the accuracy of the device measurement.

[0084] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
