Description

Technical Field

[0001] The utility model relates to the technical field of smoothing reactors, and particularly relates to a hollow self-cooling smoothing reactor. Background Technique

[0002] A smoothing reactor refers to an electronic device used in the DC circuit after rectification. The number of pulses of the rectifier circuit is always limited, and there are always ripples in the output rectified voltage. Such ripples are often harmful and need to be suppressed by a smoothing reactor. Smoothing reactors are installed in the converter stations of DC power transmission to make the output DC approach ideal DC. In the thyristor electric drive powered by DC, a smoothing reactor is also indispensable. The smoothing reactor and the DC filter together constitute the DC harmonic filtering circuit on the DC side of the high-voltage DC converter station. The smoothing reactor is generally connected in series between the DC output terminal of each pole converter and the DC line, and is one of the important devices of the high-voltage DC converter station.

[0003] The hollow self-cooling smoothing reactor is one of the commonly used smoothing reactors. It realizes heat dissipation through the air duct of its own structure. However, as the high-load use time of the hollow self-cooling smoothing reactor extends, the heat generation of the hollow self-cooling smoothing reactor gradually increases. When the heat dissipation capacity of the air duct cannot be satisfied, it is easy to cause the hollow self-cooling smoothing reactor to be overheated, which not only affects the smoothing effect of the hollow self-cooling smoothing reactor, but also affects the reliability and service life of the hollow self-cooling smoothing reactor.

[0019] A hollow self-cooling smoothing reactor, in combination with Figure 1 As shown, it includes a hollow self-cooling smoothing reactor body. The hollow self-cooling smoothing reactor body includes a plurality of hollow windings 1, and the plurality of windings 1 are connected in sequence and arranged longitudinally. The winding 1 includes a plurality of coil cakes, and the coil cakes are connected in sequence and arranged one by one in a nested manner. A plurality of separators 2 are arranged between adjacent windings 1. As Figure 2 shown, the separator 2 is comb-shaped, including a horizontally arranged main body and a plurality of separating columns arranged at intervals on the main body; adjacent windings 1 are separated by the main body of the separator 2, so that a radial air duct is formed between adjacent windings 1; adjacent coil cakes on the same winding 1 are separated by the separating columns of the separator 2, so that an axial air duct is formed between adjacent coil cakes. Through the axial air duct and the radial air duct, the hollow self-cooling smoothing reactor body has a good self-cooling effect.

[0020] A plurality of upper square clamping cylinders 3 are arranged at the top of the hollow self-cooling smoothing reactor body, and the plurality of upper square clamping cylinders 3 are arranged in an array; a plurality of lower square clamping cylinders 4 are arranged at the bottom of the hollow self-cooling smoothing reactor body, and the plurality of lower square clamping cylinders 4 are also arranged in an array. Each upper square clamping cylinder 3 and each lower square clamping cylinder 4 are arranged opposite to each other, and pull rods 5 are respectively inserted through the two ends of the opposite upper square clamping cylinder 3 and lower square clamping cylinder 4. Through the pull rods 5, the upper square clamping cylinder 3 and the lower square clamping cylinder 4 can be clamped to the hollow self-cooling smoothing reactor body, so as to realize the overall fixation of the hollow self-cooling smoothing reactor body.

[0021] A support body 6 is arranged at the bottom of each lower square clamping cylinder 4, and a bottom plate 7 is arranged at the bottom of each support body 6, so as to support the hollow self-cooling smoothing reactor body above the bottom plate 7.

[0022] The bottom plate 7 is provided with a fan 8, a wind box 9 and a wind tube 12, and the fan 8, the wind box 9 and the wind tube 12 are sequentially connected through a wind duct. The fan 8 is used to draw air into the wind box 9. Figure 4 As shown, a dehumidification plate 10 and a dust removal plate 11 are sequentially arranged in the wind box 9 along the direction of the wind flow toward the wind tube 12. The dehumidification plate 10 is used to dehumidify the wind, and the dust removal plate 11 is used to remove dust from the wind.
