Description

Technical Field

[0001] The present invention belongs to the technical field of reactors, and in particular relates to a reactor with a noise reduction function. Background Art

[0002] Reactors, also known as inductors, are widely used in circuits to prevent current changes. All current-carrying conductors have some inductance, but a straight conductor with current flowing through it has a low inductance and generates a weak magnetic field. Therefore, a typical reactor is a wire wound into a solenoid, known as an air-core reactor. Sometimes, to increase the inductance of a solenoid, an iron core is inserted into the solenoid, known as an iron-core reactor. Reactance is divided into inductive reactance and capacitive reactance. A more scientific classification is that inductive reactance and capacitive reactance are collectively referred to as reactors. Existing reactors have the following problems when used:

[0003] 1. Harmonic currents generated by nonlinear loads in the power grid, such as inverters and arc furnaces, increase the fluctuation amplitude of the magnetic flux density in the reactor core, exacerbating the magnetostrictive effect and triggering a resonant response. This causes the reactor to generate large vibration noise during operation. Vibration causes components on the reactor to loosen, and the coupling of loose components further exacerbates the noise generation. Existing reactors usually use sound insulation covers and shock-absorbing pads to reduce noise. However, this noise reduction method is ineffective and cannot improve the loose components caused by vibration.

[0004] 2. During operation, the electromagnetic loss of the winding resistance, the magnetic loss of the core, and the harmonic current all cause the reactor to generate a large amount of heat, necessitating heat dissipation. Existing reactor heat dissipation methods include air cooling and oil-immersed liquid cooling. Oil-immersed cooling is effective, but the insulating oil itself has poor fluidity during oil-immersed cooling, resulting in slow heat conduction and prone to local overheating. In addition, the insulating oil is usually naturally heat-exchanged using cooling fins, which results in relatively slow heat exchange efficiency and speed. Summary of the Invention

[0034] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0035] Example: See Figure 1 and Figure 2 A reactor with noise reduction function includes a fuel tank 1. Two vibration-damping bases 2 for supporting and reducing vibration of the fuel tank 1 are symmetrically arranged at the front and back of the bottom of the fuel tank 1. A supporting plate 8 is installed on the bottom surface of the fuel tank 1. The fuel tank 1 is a double-layer hollow structure, and the hollow part is a cavity. A number of sound-absorbing triangular cones 10 are evenly installed in the cavity of the side wall of the fuel tank 1. A buffer mechanism 7 is provided on the top of the supporting plate 8. A number of reactor bodies 5 are fixedly installed on the top of the buffer mechanism 7. The buffer mechanism 7 is used to buffer and reduce vibration of the reactor body 5. A number of self-locking fixing mechanisms 6 are provided on the reactor body 5. A circulating heat dissipation mechanism 3 for circulating cooling and heat dissipation is provided on the fuel tank 1. An upper cover 4 is fixedly installed on the top of the fuel tank 1. A sealing ring is provided between the upper cover 4 and the fuel tank 1. The inside of the fuel tank 1 is filled with insulating oil.

[0036] When in use, the support plate 8 is used to support and fix the buffer mechanism 7, the vibration-damping base 2 is used to perform vibration reduction and buffering on the entire oil tank 1, and the silencer triangle 10 is evenly arranged in the cavity of the side wall of the oil tank 1. The silencer triangle 10 achieves noise reduction by multi-directionally reflecting the noise generated by the reactor body 5 and dispersing the propagation direction of the sound wave to weaken the energy concentration effect. The self-locking fixing mechanism 6 is used to achieve stable installation of various components in the reactor body 5 to avoid loosening of the components of the reactor body 5 due to vibration. The circulating heat dissipation mechanism 3 is used to achieve oil-immersed rapid circulating heat dissipation, and the sealing ring is used to ensure the seal between the upper cover 4 and the oil tank 1.

[0037] See also Figure 2 、 Figure 3 and Figure 4 The self-locking fixing mechanism 6 includes a top fixing block 65 fixedly connected to the top of the reactor body 5 and a bottom fixing block 61 fixed to the bottom of the reactor body 5. A screw 62 is inserted through the top fixing block 65 and the bottom fixing block 61 for mutual movement. A threaded hole is provided at the top center of the screw 62, and a locking assembly 63 is threadedly connected to the inside of the threaded hole. A nut 64 is threadedly connected to the upper part of the screw 62.

[0038] See also Figure 3 、 Figure 4 、 Figure 5 and Figure 6 A number of slots are evenly opened on the top of the nut 64, and a No. 1 gasket 67 is attached to the bottom of the nut 64. A rubber ring 66 is fixedly installed on the bottom of the No. 1 gasket 67, and a No. 2 gasket 69 is fixedly installed on the bottom of the rubber ring 66. The bottom of the No. 2 gasket 69 is attached to the top of the top fixed block 65. A number of mounting holes are evenly opened inside the rubber ring 66, and a spring 68 is arranged inside the mounting hole. The spring 68 is arranged between the No. 1 gasket 67 and the No. 2 gasket 69. The locking assembly 63 includes a screw 631 threadedly connected to the inside of the threaded hole, and a number of fixed arms 632 are evenly rotated and installed on the outside of the screw 631. A crimping block 633 is fixedly installed on the bottom of the fixed arm 632, and a crimping ring 634 is fixedly installed on the bottom of multiple crimping blocks 633. A clip 635 fixedly installed on the bottom of the crimping ring 634 is fixedly installed with a card slot.

[0039] When in use, first pass the screw 62 between the bottom fixing block 61 and the top fixing block 65, then put the whole consisting of the No. 2 gasket 69, the rubber ring 66 and the No. 1 gasket 67 onto the screw 62, and then use the nut 64 to tighten and fix the screw 62. When the nut 64 is tightened, the elasticity of the rubber ring 66 and the spring 68 ensures that the nut 64 is in a tensioned state, achieving a first-level locking of the nut 64, and achieving the fixation between the bottom fixing block 61 and the top fixing block 65, thereby achieving stable installation of the components inside the reactor body 5. After tightening the nut 64, screw the screw 631 into the threaded hole at the top of the screw 62. At this time, as it is tightened, the fixing arm 63 is driven 2 and the crimping block 633 thereon move downward, synchronously driving the crimping ring 634 and the clamping strip 635 thereon to move downward. When the clamping strip 635 is about to be crimped onto the nut 64, the fixed arm 632 is rotated along the axis of the screw 631, indirectly driving the clamping strip 635 to rotate, aligning the clamping strip 635 with the slot position, and continuing to rotate the screw 631 until the clamping strip 635 is clamped into the slot on the nut 64. The crimping of the clamping strip 635 further realizes the anti-loosening locking of the nut 64, effectively avoiding the loosening of the nut 64 caused by vibration, ensuring the tight installation of the internal components of the reactor body 5, avoiding the noise caused by loose parts and collisions, and reducing the generation of noise.

[0040] See also Figure 2 and Figure 3 The buffer mechanism 7 includes two No. 1 fixing plates 72 fixedly mounted on the top of the supporting plate 8, and ear plates 71 are fixedly mounted on both sides of the No. 1 fixing plate 72.

[0041] During use, when the reactor body 5 vibrates, the vibration is transmitted to the first rubber plate 73, the wooden board 74 and the second rubber plate 75. The first rubber plate 73, the wooden board 74 and the second rubber plate 75 cushion and absorb the vibration, reducing the vibration transmitted to the oil tank 1, thereby achieving primary noise reduction of the reactor body 5. The insulating oil stored in the oil tank 1 has the function of absorbing vibration while dissipating heat, further reducing vibration and noise. At the same time, the subsequent vibration and noise are reduced from being transmitted to the cavity, and the silencer triangular cone 10 in the cavity is used to absorb sound and reduce noise, thereby achieving secondary noise reduction.

A number of elastomers 25 are evenly installed on the bottom surface of the U-shaped channel steel 26. A spring piece 24 is fixedly installed on the top of the elastomer 25.

[0043] During use, the absorbed vibration is transmitted to the support rod 22, then to the support plate 23, and then to the rubber seat 21. The rubber seat 21 performs buffering and vibration reduction through elasticity, and the vibration is transmitted to the elastomer 25 and the spring piece 24 on the U-shaped channel steel 26, driving the elastomer 25 and the spring piece 24 to vibrate, and evenly dispersing the vibration to each elastomer 25 and spring piece 24, realizing vibration dispersion, effectively reducing the vibration amplitude, achieving further vibration reduction and noise reduction, and realizing three-level noise reduction.

Blades 315 are rotatably mounted inside the shell 314. The boosting tank 313, the shell 314 and the blades 315 are all located inside the cavity of the oil tank 1.

[0045] See also Figure 7 、 Figure 8 、 Figure 9 and Figure 10The stirring assembly 32 includes a linkage shaft 323 that rotates in a sealed manner and passes through the left side of the shell 314. The right end of the linkage shaft 323 is fixedly connected to the left side of the blade 315. The left end of the linkage shaft 323 is fixedly sleeved with a driving bevel gear 327. A fixed shaft 325 is rotatably installed on the top of the cavity inside the oil tank 1.

The support legs 9 are used to support the oil tank 1 to prevent the problem of damage to the oil tank 1 caused by the excessive weight of the buffer mechanism 7 and the reactor body 5.

[0046] See also Figure 7 、 Figure 8 、 Figure 9 and Figure 10 The heat dissipation reflux component 33 includes a bent pipe 335 fixedly installed at the bottom of the shell 314, and a discharge pipe 336 is fixedly installed at one end of the bent pipe 335 away from the shell 314.
