Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to an iron core reactor for high voltage testing. Background Art

[0002] The iron core reactor is an electrical component whose main function is to provide reactive power compensation and voltage stability in the power system. The iron core reactor is usually composed of an iron core and a coil. The coil changes its inductance by controlling the current. Its working principle is to use the magnetic permeability of the iron core and the inductance of the coil to achieve the regulation of current and voltage. In high-voltage tests, the design and selection of iron core reactors must take into account the power requirements of the tested equipment and the stability requirements of current and voltage.

[0003] In high-voltage experiments, the access method of iron-core reactors is usually through insertion. Through the insertion method, the iron-core reactor can be easily connected to the tested equipment and easily disconnected when needed. At the same time, the insertion method allows the position and connection method of the iron-core reactor to be adjusted as needed to meet the experimental requirements.

[0004] However, the insertion connection is prone to loosening, which will lead to unstable electrical connection and affect the current and voltage transmission, resulting in inaccurate measurement results or distorted experimental data. At the same time, loose connection will cause safety problems such as arc discharge, short circuit or fire. Unstable connection will cause overheating, electric shock and other dangerous situations, causing harm to personnel and equipment. Therefore, a high-voltage test iron core inductor is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Specifically, after the connecting line is connected, the rotation can be achieved by driving the rotating ring 9. When the rotating ring 9 rotates, it will move through the rotation. The limit groove 10 inside the rotating ring 9 can push the driving block 13, and then the driving block 13 pushes the piston plate 11 through the connecting rod 12. In this way, the piston plate 11 will slide inside the inflation tube 8. When the piston plate 11 slides inside the inflation tube 8, the gas inside the inflation tube 8 will be discharged into the rubber airbag 7. In this way, the rubber airbag 7 will inflate, and the inflated rubber airbag 7 will clamp the connecting line, thereby ensuring the stability of the connecting line connection.

[0034] Reference Figure 1 and Figure 2 A protective component is provided on the top of the top cover 5, and the protective component includes a lightning rod 6 and a pressure relief valve 2, one end of the pressure relief valve 2 is fixedly connected to the inside of the body 1, and the bottom of the lightning rod 6 is fixedly connected to the top of the top cover 5;

[0035] Specifically, a pressure relief valve 2 is provided on the main body 1. When the temperature and air pressure inside the main body 1 are too high, the gas can be discharged through the pressure relief valve 2. A lightning rod 6 is provided on the top of the top cover 5 to effectively protect the iron core reactor from lightning.

[0036] Reference Figure 2 and Figure 4 The outer wall of the body 1 is fixedly connected with a plurality of hanging plates 4, and a rotating shaft 20 is rotatably connected inside the hanging plate 4. A worm wheel 19 is fixedly connected to one side of the outer wall of the rotating shaft 20, and a worm 17 is rotatably connected to one side of the inner wall of the hanging plate 4. The worm 17 is meshed with the outer wall of the worm wheel 19, and a handle 16 is fixedly connected to one end of the worm 17. Slide grooves 14 are provided on both sides of the inner wall of the hanging plate 4, and a gear 21 is fixedly connected to one side of the outer wall of the rotating shaft 20. Clamps 15 are provided on both sides of the inner wall of the hanging plate 4, and the outer wall of the clamp 15 is slidably connected to the inner wall of the slide groove 14. A rack 18 is fixedly connected to one side of the outer wall of the slide groove 14, and the gear 21 is meshed with the rack 18;

[0037] Specifically, the main body 1 can be suspended by the hanging plate 4, and then the handle 16 is used to drive the worm 17 to rotate. The rotation of the worm 17 can drive the worm wheel 19 to rotate, and then drive the rotating shaft 20 to rotate. Through the connection of the rotating shaft 20, the gear 21 will also rotate accordingly. Under the rotation of the gear 21, the racks 18 on both sides will synchronously move relative to each other. When the racks 18 move relative to each other, they will respectively drive the clamps 15 on both sides to move. In this way, the clamps 15 on both sides will clamp inward, thereby increasing the installation stability of the main body 1. Through this process, through the rotation of the handle 16, the transmission devices such as the worm 17 and the worm wheel 19 drive the rotation of the rotating shaft 20 and the gear 21. As the gear 21 rotates, the relative movement of the racks 18 on both sides enables the clamps 15 to clamp the main body 1, thereby ensuring its installation stability. This design can conveniently adjust the position of the main body 1 through manual operation, and maintain its stability through the clamping of the clamps 15.

[0038] Working principle: after the connecting line is connected, the rotating ring 9 can be driven to rotate, and the rotating ring 9 will move by rotating, then the limiting groove 10 inside the rotating ring 9 can push the driving block 13, and then the driving block 13 pushes the piston plate 11 through the connecting rod 12, so that the piston plate 11 slides inside the inflation tube 8, and the gas inside the inflation tube 8 will be discharged into the rubber airbag 7, so that the rubber airbag 7 will expand, so that the connecting line will be clamped by the rubber airbag 7, thereby ensuring the stability of the connection of the connecting line, the main body 1 can be hung by the hanging plate 4, and then the worm 17 can be driven to rotate by the handle 16, and the rotation of the worm 17 can drive the worm wheel 19 to rotate, thereby driving the rotating shaft 20 to rotate, and then through the connection of the rotating shaft 20, the gear 21 is rotated, and under the rotation of the gear 21, the racks 18 on both sides can be synchronously driven to make relative motion, and then the racks 18 on both sides respectively drive the clamping plates 15 on both sides to move, and the clamping plates 15 on both sides will clamp inward, thereby driving the stability of the installation of the main body 1.
