Description

Technical Field

[0001] The present application relates to the technical field of reactors, and in particular to a reactor shielding structure. Background Art

[0002] In a flexible HVDC transmission system, phase reactors are key components of converter stations. They facilitate power exchange between the voltage source converter (VSC) and the AC system, determining the converter's power transmission capacity and controlling active and reactive power. Furthermore, phase reactors suppress switching frequency harmonics in the converter's output current and voltage. When a system disturbance or short circuit occurs, phase reactors can dampen the current rise rate and limit the peak short-circuit current.

[0003] After searching, the Chinese patent publication number CN204991410U discloses a reactor with a shielding structure, which includes a hollow reactor and a metal shielding cover. The hollow reactor is placed inside the metal shielding cover and is separated from the metal shielding cover by a distance; the metal shielding cover includes four metal brackets and at least two annular closed metal conductors arranged in parallel up and down.

[0004] The reactor with a shielding structure in the above patent has the following shortcomings: in the above patent, multiple annular closed metal conductors are arranged on a metal bracket. During actual use, the closed metal conductors are directly fixed on the metal bracket. Once the annular closed metal conductors are damaged, it is inconvenient to disassemble and replace them.

Because of the effect of electromagnetic induction in the circuit, there is a certain inductance, which can prevent current changes. In order to ensure the normal operation of the reactor, the reactor needs to be protected by a shielding structure, thereby ensuring the normal operation of the reactor. It includes a base 1 and a shielding cover 3 installed on the base 1. The top outer wall of the base 1 is fixedly connected to the reactor body 2, and the reactor body 2 is located inside the shielding cover 3. The reactor is protected by the shielding cover 3, thereby ensuring the normal operation of the reactor. The shielding cover 3 includes three support frames 4 fixedly connected to the base 1, and multiple shielding mechanisms 5 are installed on the outer walls of the three support frames 4. The cross-section of the support frame 4 is an H-shaped structure. The setting of the support frame 4 is convenient for supporting and installing the shielding mechanism 5. Multiple shielding mechanisms 5 are combined to form a shielding cover 3 to protect the reactor.

The shielding ring 6, the support frame 4 and the mounting assembly 7 are all metal structures. The combination of multiple shielding rings 6 forms a shielding cover 3 to provide anti-interference protection for the inductor body 2. The setting of the mounting assembly 7 facilitates the installation and fixation of the shielding ring 6. A single shielding ring 6 needs to be installed through three mounting assemblies 7. The outer wall of the shielding ring 6 is fixedly connected with three equidistantly distributed connecting seats 8, and a mounting opening 9 is provided on the outer wall of the top of the connecting seat 8. The connecting seat 8 protrudes from the outer wall of the shielding ring 6.

One end of the worm 23 is fixedly connected to a rotating part 15, and the rotating part 15 cooperates with a socket wrench to directly drive the worm 23 to rotate. When the worm 23 rotates, it directly drives the worm wheel 22 to rotate, thereby facilitating the L-shaped seat 16 to clamp and fix the shielding ring 6. The worm 23 is driven to rotate by the rotating part 15. When the worm 23 rotates, it directly drives the worm wheel 22 to rotate. When the worm wheel 22 rotates, it drives the gear 20 to rotate, thereby facilitating the driving of the two L-shaped seats 16 to be inserted into the installation port 9.

[0042] The implementation principle of this application is as follows: during use, when the shielding cover 3 needs to be installed, first fix the three support frames 4 on the base 1, and then install the mounting assembly 7 on the shielding ring 6. During installation, first place the connecting seat 8 on the shielding ring 6 between the two L-shaped seats 16, and then rotate the rotating part 15. When the rotating part 15 rotates, it directly drives the worm 23 to rotate, and when the worm 23 rotates, it directly drives the worm gear 22 to rotate. When the worm gear 22 rotates, it directly drives the gear 20 to rotate. When the gear 20 rotates, it drives the two racks 21 to move toward or away from each other. When the two racks 21 move toward each other, they directly drive the two drive seats 18 to move toward each other. When the drive seat 18 moves, it directly drives the L-shaped seat 16 to be inserted into the mounting port 9, and then the mounting seat 10 is sleeved on the outer wall of the support frame 4. When the mounting seat 10 moves to the specified position, the two locking bolts 12 are tightened to drive the pressing seat 13 to press on the support frame 4, thereby facilitating the installation of the shielding ring 6.
