Description

Technical Field

[0001] The utility model relates to the field of power equipment, in particular to a device for filtering current harmonics. Background Art

[0002] Harmonics refer to the electric quantity in the current whose frequency is an integer multiple of the fundamental wave. Generally, it refers to the electric quantity generated by the current with a frequency higher than the fundamental wave frequency after the periodic non-sinusoidal electric quantity is decomposed by Fourier series. Broadly speaking, since the effective component of the AC power grid is a single power frequency, any component different from the power frequency can be called current harmonics.

[0003] The existence of current harmonics will affect the stable operation of the power system and the power quality, resulting in problems such as reduced operation efficiency of the power system, overheating of electrical equipment, vibration and noise generation, and insulation aging. Therefore, a device is needed to reduce the harmonics transmitted by the cable current. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a device for filtering current harmonics, which can effectively reduce the current harmonics of the cable and can be installed without power outage of the cable.

[0005] The technical solution adopted by the device for filtering current harmonics disclosed by the utility model is as follows:

[0006] It includes a main body, the main body includes a reaction column, a first reaction layer, a second reaction layer, a first protective layer, a second protective layer and a third protective layer are sequentially sleeved outside the reaction column. The reaction column contains cobalt metal elements, the first reaction layer contains nickel metal elements, the second reaction layer contains iron oxide material, the first protective layer contains magnesium metal elements, the second protective layer contains magnesium oxide material, the third protective layer contains aluminum oxide material. The cross-section of the main body is polygonal, and a plastic film is sleeved outside the third protective layer, and the plastic film is in contact with the cable.

[0007] As a preferred solution, the cross-section of the main body is hexagonal.

[0008] As a preferred solution, spacers are provided at both ends of the third protective layer, and the plastic film wraps the spacers.

[0009] As a preferred solution, it further includes a plurality of cable ties. One side of the main body is clamped between two cables, the outside of the main body is in contact with the two cables, and the cable ties are sleeved outside the cable and the main body.

[0010] The beneficial effect of the device for filtering current harmonics disclosed by the utility model is:

[0011] Attach the main body to the cable. Through the action of the reaction column, the first reaction layer, the second reaction layer, the first protective layer, the second protective layer, and the third protective layer on the main body on the current generated by the cable, the current is unable to carry away energy, effectively reducing the current harmonics of the cable during power transmission and reducing the impact of current harmonics on the power system. The plastic film can protect the reaction column, the first reaction layer, the second reaction layer, the first protective layer, the second protective layer, and the third protective layer inside the main body, preventing external water vapor from eroding the main body and extending the service life of the main body. The main body only needs to be close to the cable to achieve the current harmonics of the cable during power transmission, enabling this device to adapt to most existing power systems on the market and improving the versatility of this device.

[0015] The following further elaborates and explains the present utility model in combination with specific embodiments and the drawings of the specification:

[0016] Please refer to Figure 1 .

[0017] A device for filtering current harmonics disclosed by the present utility model is used to reduce the current harmonics of the cable 3. This device includes a main body 1 and a cable tie 2.

[0018] Please refer to Figure 2 .

[0019] The main body 1 includes a reaction column 11. The outer side of the reaction column 11 is successively sleeved with a first reaction layer 12, a second reaction layer 13, a first protective layer 14, a second protective layer 15, and a third protective layer 16;

[0020] Furthermore, the reaction column 11 contains cobalt metal elements. The metal element cobalt has the ability to absorb and guide magnetic fields, effectively blocking electromagnetic interference generated outside the main body 1;

[0021] Furthermore, the first reaction layer 12 contains nickel metal elements. The metal element nickel has good electromagnetic shielding performance and can effectively absorb and shield magnetic fields;

[0022] Further, the second reaction layer 13 contains iron oxide material. Iron oxide has the performance of anti-electromagnetic interference and good magnetic characteristics, which can effectively improve the anti-interference performance of the cable 3 in contact with it.

[0023] Further, the first protective layer 14 contains magnesium metal element. The metal element magnesium is light in weight, and can reduce the weight of the main body 1 while maintaining the protective performance of the first protective layer 14.

[0024] Further, the second protective layer 15 contains magnesium oxide material. Magnesium oxide has the effect of resisting acid corrosion, which can prevent the main body 1 from being corroded by external water vapor during use and improve the service life of the main body 1.

[0025] Further, the third protective layer 16 contains aluminum oxide material. Aluminum oxide can make the third protective layer 16 have a high hardness and strong corrosion resistance, which can effectively protect the main body 1 from being corroded by external water vapor during use and further improve the service life of the main body 1.

[0026] Please refer to Figure 2 and Figure 3 .

[0027] Spacers 161 are provided at both ends of the third protective layer 16. A plastic film 162 is sleeved outside the third protective layer 16. Since there will be two openings when the plastic film 162 is encapsulated on the third protective layer 16, the two spacers 161 respectively cover the two openings. The plastic film 162 wraps the reaction column 11, the first reaction layer 12, the second reaction layer 13, the first protective layer 14, the second protective layer 15, the third protective layer 16 and the spacers 161, which can effectively protect the main body 1 from being corroded by external water vapor during use and further improve the service life of the main body 1.

[0028] Please refer to Figure 1 and Figure 2 .

[0029] The cross-section of the main body 1 is polygonal. In this embodiment, it is preferably that the cross-section of the main body 1 is hexagonal. Since most of the cables 3 on the market are cylindrical, when two cables 3 are attached, two triangles are formed between the two cables 3. One side of the main body 1 can be inserted into the triangle between the two cables 3, and the six outer surfaces of the main body 1 can respectively contact six cables 3. The main body 1 contacts the cable 3 through the plastic film 162. When there are too many cables 3 in a single power system, a single hexagonal main body 1 can efficiently reduce the current harmonics of six cables 3 during power transmission.

[0030] The cable tie 2 is sleeved outside the cable 3 and the main body 1 to fix the main body 1 outside the cable 3. It is realized that the worker can place the main body 1 outside the cable 3 of the power system and fix the main body 1 outside the cable 3 with the cable tie 2 without stopping the operation of the power system.

[0031] During operation, due to the stacked arrangement relationship of the reaction column, the first reaction layer, and the second reaction layer, the current passing through the cable can simulate the characteristics of a quantum mechanics superconducting material. An ideal superconductor will exhibit a zero-resistance state below a specific temperature, and even if the specific temperature is not reached, it still has the property of perfect diamagnetism, through which a strong magnetic field can be generated. The superconductor oscillates at a frequency of hundreds of thousands of times per second in microwave, causing its magnetic fields to superimpose on each other to generate strong cutting lines, making conductive molecules and free molecules finer, improving the conductivity coefficient in the current loop, avoiding the electrostatic interaction between molecules and atoms, and the finer single molecules have better conductivity, which can improve the conduction efficiency and thus reduce the loss caused by the cable during power transmission.

[0032] The present utility model provides a device for filtering current harmonics. The main body is attached to the cable, and the current generated by the cable acts on the conductive molecules through the reaction column, the first reaction layer, the second reaction layer, the first protective layer, the second protective layer, and the third protective layer on the main body, so that the current cannot carry away energy, effectively reducing the current harmonics of the cable during power transmission and reducing the impact of current harmonics on the power system; the plastic film can protect the reaction column, the first reaction layer, the second reaction layer, the first protective layer, the second protective layer, and the third protective layer in the main body, preventing external water vapor from eroding the main body and extending the service life of the main body; the main body only needs to be close to the cable to achieve the current harmonics of the cable during power transmission, enabling this device to adapt to most existing power systems on the market and improving the versatility of this device.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting the protection scope of the present utility model. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present utility model.
