The fixing frame supports the main body through the shock absorption device, so that the main body has certain shock absorption performance, and the top of the counterweight block supports the fixing frame through the support rod. The counterweight block is placed under the main body to lower the overall center of gravity, further improve the stability of the main body, and improve the protection of the equipment. A mounting frame and a handle are set on the top of the fixing frame for easy carrying by staff.

Collisions may occur during movement, and it may be affected by wind, rain, vibration, etc. when used outdoors. These external shocks may cause damage to the precision components inside the line loss analyzer, affecting its measurement accuracy and stability, and thus affecting the accuracy of line loss analysis.

An opening and closing mechanism is provided on the front side of the protective shell 2.

[0027] As attached Figure 1 、 2 As shown in , 3, and 6, the opening and closing mechanism includes a rotating door panel 12, which is arranged on the front side of the protective shell 2, and a hinge 13 is fixedly installed between the rotating door panel 12 and the protective shell 2. A through groove 14 is provided on the front surface of the rotating door panel 12, and a transparent observation window 15 is fixedly installed inside the through groove 14. A card slot 21 is provided on the front surface of the protective shell 2, and the front side of the rotating door panel 12 is fixedly connected to a fixed shell 16. A threaded hole 17 is provided on one side surface of the fixed shell 16, and a threaded rod 18 is threadedly connected to the threaded hole 17. The threaded rod 18 is threadedly connected to the threaded rod 18. 8 is provided with a movable card plate 22 at one end, and a bearing 19 is fixedly installed between the threaded rod 18 and the movable card plate 22. A through slide groove 20 is provided on the surface of one side of the rotating door panel 12, and the through slide groove 20 is slidably connected with the movable card plate 22. The movable card plate 22 is movably connected with the card groove 21, which is convenient for fixing the protective shell 2 and the rotating door panel 12, thereby improving the protection effect of the substation line loss analyzer 1 and preventing the rotating door panel 12 from opening due to external collision, thereby further improving the fixed protection effect of the substation line loss analyzer 1.

[0028] As attached Figure 2 、 4As shown in , 5, the fixing sleeve 5 is slidably connected to the groove 8, the fixing rod 7 is slidably connected to the inner wall of the fixing sleeve 5, the elastic block 10 is made of natural rubber, and the buffer protection plate 3 can be made of polystyrene foam, which improves the protective buffering effect of the substation line loss analyzer 1 and prevents the substation line loss analyzer 1 from being damaged by impact.

[0029] As attached Figure 1-6 As shown, a lifting rod 24 is fixedly installed on the top of the protective shell 2, and an anti-slip cover 25 is fixedly provided on the outer side of the lifting rod 24 to facilitate carrying the device.

[0030] Working principle of the utility model: During use, the low-voltage distribution transformer area line loss analysis device provided by the utility model, when external impact force acts on the protective shell 2, the buffer protective plates 3 on both sides of the inner wall of the protective shell 2 are first squeezed. The buffer protective plates 3 can be made of polystyrene foam and have good buffering performance. After the buffer protective plates 3 are subjected to force, they push the fixed sleeve 5 to slide in the limiting slide groove 4. At the same time, the fixed sleeve 5 moves into the groove 8 and compresses the spring 6. One end of the spring 6 is fixedly connected to one side of the inner wall of the fixed sleeve 5, and the other end is fixed to the fixed rod 7. The spring 6 absorbs the impact force through compression deformation and plays a buffering role. When the protective shell 2 is subjected to impact force in the up and down directions, the impact force is transmitted to the fixed grooves 9 at the top and bottom of the inner wall of the protective shell 2. The elastic block 10 in the fixed groove 9 is made of natural rubber and has good elasticity. After the buffer block 11 on the top of the elastic block 10 is subjected to pressure, the elastic block 10 is compressed and deformed, thereby absorbing the impact force in the up and down directions;

[0031] When the rotating door panel 12 is opened, the rotating door panel 12 is connected to the protective shell 2 through the hinge 13 and can be rotated to open around the hinge 13. After opening, the internal station line loss analyzer 1 can be operated or maintained. When the rotating door panel 12 is closed and fixed, a transparent observation window 15 is installed in the through groove 14 on the front surface of the rotating door panel 12, so that the status of the internal equipment can be observed without opening the door panel. After closing the rotating door panel 12, the threaded rod 18 is rotated. The threaded rod 18 is connected to the fixed shell 16 through the threaded hole 17, and one end of the threaded rod 18 is connected to the movable card plate 22 through the bearing 19. When the threaded rod 18 is rotated, the movable card plate 22 is slidably connected to the through slide groove 20, which limits the rotation of the movable card plate 22, so that the movable card plate 22 can only move horizontally along the through slide groove 20. The movable card plate 22 moves toward the card slot 21 and is finally stuck in the card slot 21, firmly fixing the rotating door panel 12 to the front side of the protective shell 2.

[0032] The low-voltage distribution transformer substation line loss analysis device provides all-round protection for the substation line loss analyzer 1 through the protective shell 2 and the internal protective mechanism and opening and closing mechanism. When subjected to external impact force, the spring 6, buffer protection plate 3, elastic block 10 and buffer block 11 in the protective mechanism work together to absorb and disperse the impact force, protecting the substation line loss analyzer 1 from damage. The opening and closing mechanism facilitates the operation and maintenance of the equipment, while ensuring that the door panel can be firmly fixed in the closed state to prevent accidental opening. The lifting rod 24 on the top of the protective shell 2 and the anti-slip sleeve 25 on the outside make it easy to carry and move the entire device.

[0033] Finally, the above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical concepts disclosed in this utility model are intended to be covered by the claims of this utility model.
