Technical Field

[0001] The present invention relates to the field of substations, and particularly to a dust-proof elbow assembly and a substation thereof. Background Art

[0002] A substation refers to a place in the power system where voltage and current are transformed, and electric energy is received and distributed. The substation in a power plant is a step-up substation, whose function is to step up the electric energy generated by the generator and feed it into the high-voltage power grid. Since the working voltage of the substation is very high, it is necessary to dissipate heat from the substation in time to avoid overheating and causing spontaneous combustion of the substation.

[0003] However, the high-voltage room of the substation is ventilated through pipelines, and at the same time, foreign matters such as dust from the outside are carried into the high-voltage room of the substation. The long-term accumulation of dust and other foreign matters entering the interior of the substation increases the risks of erosion and short circuit of the components and circuits in the substation. Summary of the Invention

The first arc is located on the side of the second arc away from the high-voltage room, and in the air inlet direction, the maximum distance between the first arc and the second pipe section is greater than the maximum distance between the second arc and the second pipe section.

[0008] In some embodiments, the air inlet holes further include two third arc segments, and the two third arc segments are respectively connected between the two ends of the first arc and the two second arcs.

[0009] In some embodiments, the dust-proof elbow assembly further includes a bracket and a follower vane. The bracket is disposed in the first pipe section and / or the second pipe section, and the follower vane is rotatably disposed on the bracket.

[0010] In some embodiments, the dust-proof elbow assembly further includes a filter module, and the filter module is disposed in the first pipe section and / or the second pipe section.

[0032] Embodiment 1

[0033] As Figures 1 - 3 shown, the embodiment of the present invention provides a dust-proof elbow assembly, which is applied to a substation. The substation includes a high-voltage room. The dust-proof elbow assembly includes an elbow 1 and an arc-shaped dust-proof cover 2. One end of the elbow 1 is connected to the high-voltage room, and the arc-shaped dust-proof cover 2 is buckled on the other end of the elbow 1 and protrudes away from the elbow 1. An air inlet hole 21 is provided on the arc-shaped dust-proof cover 2.

[0034] The dust-proof elbow assembly of this embodiment is applied to a substation. Specifically, one end of the elbow 1 is connected to the high-voltage room of the substation, and the high-voltage room is ventilated through the elbow 1. When ventilating, it is easy to carry dust into the elbow 1. In this embodiment, the arc-shaped dust-proof cover 2 is buckled on the other end of the elbow 1. Since the arc-shaped dust-proof cover 2 protrudes away from the elbow 1, when air enters through the air inlet hole 21 on the arc-shaped dust-proof cover 2, a part of the dust can be blocked by the outer arc surface of the arc-shaped dust-proof cover 2. Therefore, the dust-proof elbow assembly of this embodiment can play a role in blocking dust from entering, preventing foreign objects such as dust from entering the high-voltage room of the substation through the elbow 1, reducing the risk of erosion and short circuit of the components and circuits in the substation, and improving the stability of the operation of the substation.

[0035] In some embodiments, the elbow pipe 1 includes a first pipe section 11, a second pipe section 12, and a bending portion 13 located between the first pipe section 11 and the second pipe section 12 and making a preset angle between the first pipe section 11; one end of the first pipe section 11 away from the bending portion 13 is connected to the high-pressure chamber; the arc-shaped dust shield 2 is fastened to one end of the second pipe section 12 away from the bending portion 13, and one end of the second pipe section 12 away from the bending portion 13 extends downward.

[0036] In this embodiment, the bending portion 13 makes a preset angle between the first pipe section 11 and the second pipe section 12 of the elbow pipe 1. The preset angle can be 90° or other angles, and the specific angle can be selected according to user needs; in this embodiment, one end of the first pipe section 11 of the elbow pipe 1 away from the bending portion 13 is connected to the high-pressure chamber; one end of the second pipe section 12 away from the bending portion 13 extends downward, so that the air inlet hole 21 of the arc-shaped dust shield 2 faces downward. Therefore, in the second pipe section 12, the air flow flows from bottom to top. The structure of this embodiment can also filter some foreign matters such as dust by gravity, prevent foreign matters such as dust from entering the high-pressure chamber of the substation through the elbow pipe 1, reduce the risk of erosion and short circuit of the components and circuits in the substation, and improve the stability of the substation operation.

[0037] In some embodiments, the air inlet hole 21 includes a first arc 211 and two second arcs 212 respectively connected to both ends of the first arc 211. The two second arcs 212 are connected at the ends away from the first arc 211. The first arc 211 is located on the side of the second arc 212 away from the high-pressure chamber, and in the air inlet direction, the maximum distance between the first arc 211 and the second pipe section 12 is greater than the maximum distance between the second arc 212 and the second pipe section 12.

[0038] In this embodiment, the air inlet hole 21 is formed by enclosing the first arc 211 and two second arcs 212 respectively connected to both ends of the first arc 211. Specifically, the first arc 211 is located on the side of the second arc 212 away from the high-pressure chamber, and in the air inlet direction, the maximum distance between the first arc 211 and the second pipe section 12 is greater than the maximum distance between the second arc 212 and the second pipe section 12. Therefore, the gas on the side away from the high-pressure chamber will enter the arc-shaped dust shield 2 through the air inlet hole 21 and needs to cross the top of the first arc 211. In this process, the arc-shaped dust shield 2 can block foreign matters such as dust from entering the high-pressure chamber of the substation through the elbow pipe 1, reduce the risk of erosion and short circuit of the components and circuits in the substation, and improve the stability of the substation operation.

[0039] In some embodiments, the air inlet hole 21 further includes two third arc segments 213, and the two third arc segments 213 are respectively connected between the two ends of the first arc 211 and the two second arcs 212.

[0040] In this embodiment, by connecting the two third arc segments 213 between the two ends of the first arc 211 and the second arc 212 respectively, the airflow entering the air inlet hole 21 can be made smooth while blocking dust.

[0041] In some embodiments, the dust-proof elbow assembly further includes a bracket 3 and a follower vane 4. The bracket 3 is disposed in the first pipe section 11 and / or the second pipe section 12, and the follower vane 4 is rotatably disposed on the bracket 3.

[0042] In this embodiment, by disposing the bracket 3 in the first pipe section 11 and / or the second pipe section 12 and rotatably disposing the follower vane 4 on the bracket 3, during the process of air flow entering, the follower vane 4 is driven by the air flow to rotate. And during the rotation of the follower vane 4, the follower vane 4 can also block foreign matters such as dust from entering the high-voltage chamber of the substation through the elbow 1, improving the blocking effect, reducing the risk of the components and circuits in the substation being eroded and short-circuited, and improving the stability of the operation of the substation.

[0043] In some embodiments, the dust-proof elbow assembly further includes a filter module 5. The filter module 5 is disposed in the first pipe section 11 and / or the second pipe section 12. In this embodiment, by further blocking foreign matters such as dust from entering the high-voltage chamber of the substation through the elbow 1 through the filter module 5, the risk of the components and circuits in the substation being eroded and short-circuited is reduced, and the stability of the operation of the substation is improved.

[0044] In some embodiments, the filter module 5 includes a substrate and a plurality of mesh holes disposed on the substrate. In the air inlet direction, the inner diameter of the mesh holes gradually decreases.

[0045] In this embodiment, the filter module 5 is provided with a plurality of mesh holes on the substrate. In the air inlet direction, the inner diameter of the mesh holes gradually decreases. Specifically, the mesh holes are conical holes, polygonal conical holes, etc. In this embodiment, the side walls of the conical holes can block foreign matters such as dust from entering the high-voltage chamber of the substation through the elbow 1 to a certain extent, improving the blocking effect, reducing the risk of the components and circuits in the substation being eroded and short-circuited, and improving the stability of the operation of the substation.

[0046] In some embodiments, the filter module 5 includes a substrate and a plurality of mesh holes disposed on the substrate. The mesh holes include a plurality of through holes connected in sequence in the air inlet direction, and the inner diameters of the plurality of through holes gradually decrease in the air inlet direction.

[0047] In this embodiment, the filter module 5 includes a substrate and a plurality of mesh holes disposed on the substrate. The mesh holes include a plurality of through holes connected in sequence in the air inlet direction. The through holes can be round holes, polygonal holes, etc. Specifically, in the air inlet direction, the inner diameters of the plurality of through holes gradually decrease. When the through holes are round holes, the radius of the through holes decreases; when the through holes are polygonal holes, the side lengths of the through holes decrease. In this embodiment, the mesh holes are stepped holes, and the steps of the stepped holes can be used to block foreign matters such as dust from entering the high-voltage chamber of the substation through the elbow 1, improving the blocking effect, reducing the risk of erosion and short circuit of the components and circuits in the substation, and improving the stability of the operation of the substation.

[0048] In some embodiments, in the air inlet direction, the inner diameters of the respective through holes gradually decrease, and in two adjacent through holes, the minimum inner diameter of the upstream through hole is greater than the maximum inner diameter of the downstream through hole.

[0049] In this embodiment, since the inner diameters of the respective through holes gradually decrease in the air inlet direction, the tapered inner walls of the respective through holes can further block foreign matters such as dust from entering the high-voltage chamber of the substation through the elbow 1, improving the blocking effect, reducing the risk of erosion and short circuit of the components and circuits in the substation, and improving the stability of the operation of the substation.
