[0002] Power sway refers to voltage fluctuations or frequency fluctuations in the power grid. Such fluctuations may be caused by sudden failures of certain equipment in the power system, load changes, or other unstable factors. Power sway may manifest as instantaneous changes in voltage or short-term fluctuations in frequency, which may affect the power grid and connected equipment, and even cause equipment damage or system instability.

[0003] When the anti-electricity shaking device of the inverter of the steelmaking continuous casting machine on the market is used, the lines connected to the equipment generally have a certain angle, and some lines are mostly connected by direct plugging. When the equipment is maintained, the connection line may be pulled, resulting in disconnection or loosening of the line, which may cause the equipment to be unable to be used normally, or the equipment may be suddenly disconnected during use. Utility Model Content

The anti-electrical sway device is easy to implement and maintain, can reliably maintain the position of the line stable, and reduce the possibility of accidents such as line disconnection or line loosening.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings.

[0023] The anti-electrical shaking device of the steelmaking continuous casting machine inverter includes a fixed plate, which is composed of a horizontal plate 2 located at the bottom of the inverter body 1 and two vertical plates 3 located on both sides of the inverter body 1, and a connecting frame 4 is fixed at the bottom of the horizontal plate 2.

[0024] The portions of both ends of the horizontal plate 2 located between the two vertical plates 3 are provided with limiting grooves 5 .

[0025] A card plate for limiting and fixing the inverter connection line is provided at the bottom of the horizontal plate 2. The card plate consists of an upper card plate 6 and a lower card plate 7. A certain gap is left between the upper card plate 6 and the bottom of the horizontal plate 2 to facilitate the insertion of the connection line and the maintenance of the line connection angle.

[0026] Both ends of the upper clamping plate 6 and the lower clamping plate 7 are fixedly connected with positioning blocks 9 through connecting columns 8, and the positioning blocks 9 are fixed in the limiting groove 5 of the horizontal plate 2 through the limiting blocks 10 on the upper part thereof. In other words, the upper clamping plate 6 and the lower clamping plate 7 are respectively clamped in the limiting groove 5 of the horizontal plate 2 through the limiting blocks 10 on the positioning blocks 9 fixedly connected at both ends of the plates, thereby being fixed to the bottom of the horizontal plate 2.

[0027] Limiting holes 11 are correspondingly arranged on the upper card plate 6 and the lower card plate 7. The "corresponding" mentioned here means that when the upper card plate 6 and the lower card plate 7 are aligned and overlapped, the limiting holes 11 on the upper and lower card plates can at least overlap and communicate with each other. In this way, the inverter connection line can smoothly pass through the limiting holes 11 set on the upper and lower card plates. The inner periphery of the limiting hole 11 is provided with a rubber pad Ⅰ12 and a rubber pad Ⅱ13. The rubber pad Ⅰ12 and the rubber pad Ⅱ13 have high friction, buffering and insulation effects, which can ensure that the displacement of the inserted connection line is effectively limited and relatively fixed to a certain extent. The rubber pad is elastic and can also play a buffering and protective role for the connection line.

[0028] Both ends of the upper card plate 6 and the lower card plate 7 are provided with a sliding groove 14, and the connecting column 8 is movably connected in the sliding groove 14; a spring 15 is also provided in the sliding groove 14, one end of the spring 15 is fixedly connected to the connecting column 8 through a pressing block 16, and the other end of the spring 15 is fixedly connected to the inner wall of the upper card plate 6 and the lower card plate 7 on different sides. Specifically, if the other end of the spring 15 in the sliding groove 14 of the upper card plate 6 is fixedly connected to the left inner wall of the upper card plate 6, then the other end of the spring 15 in the sliding groove 14 of the lower card plate 7 is fixedly connected to the right inner wall of the lower card plate 7. In this way, it can be ensured that when the springs in the sliding grooves of the two plates are in a normal state, the upper card plate 6 and the lower card plate 7 can be pushed to opposite directions respectively, so that the upper card plate 6 and the lower card plate 7 are in a staggered state, thereby ensuring the connection angle required for the connecting line that passes through.

[0029] A sound insulation board 17 is fixed on the outer side of the vertical board 3. The sound insulation board 17 is provided with appropriate ventilation holes 18 for cooperating with the heat conducting board 19 to dissipate heat for the inverter equipment.

[0030] A heat conducting plate 19 is provided between the vertical plate 3 and the side wall of the inverter body 1. A certain gap is left between the heat conducting plate 19 and the vertical plate 3 to facilitate heat dissipation. A heat dissipation fin 20 is provided on the side of the heat conducting plate 19 close to the vertical plate 3. A small fan 21 is installed in the inner circumference surrounded by the heat dissipation fins 20. The small fan 21 is fixed in the through hole opened in the heat conducting plate 19. In this way, matching through holes are opened at the positions corresponding to the positions of the vertical plate 3 and the small fan 21 to enhance the heat dissipation effect.

[0031] When the bottom of the inverter body 1 is connected to the line, the upper card plate 6 and the lower card plate 7 are squeezed, and the springs 15 in the sliding grooves 14 of the upper and lower plates are squeezed and compressed. At this time, the connecting column 8 is fixed on the positioning block 9 and is in a stationary state, while the sliding groove 14 movably connected thereto slides relatively, and then the upper card plate 6 and the lower card plate 7 move toward each other, so as to adjust the position between the two and overlap and align them up and down, and the connected lines can be smoothly inserted through the corresponding limiting holes 11 of the upper card plate 6 and the corresponding limiting holes 11 of the lower card plate 7. After the line connection is combed, release it, and the spring 15 in the compressed state in the sliding groove 14 will instantly pop open, as mentioned above, which will push the upper card plate 6 and the lower card plate 7 to slide in opposite directions, and finally the upper card plate 6 and the lower card plate 7 are staggered, ensuring the connection angle required for the connecting line that is inserted through.
