Description

Technical Field

[0001] This utility model relates to the field of reactor soundproof cover technology, specifically a high-efficiency sound-absorbing and noise-reducing substation reactor soundproof cover. Background Technology

[0002] In the operation of power systems, substations serve as critical hubs for power transmission and conversion, and their internal reactors are essential equipment for ensuring the stable operation of the power system. Reactors typically have large capacities, and during operation, they generate significant noise due to factors such as core magnetostriction and winding vibration. Furthermore, for ease of power transmission and layout, most reactors are installed close to the substation boundary, which significantly impacts noise-sensitive buildings outside the substation (such as residential buildings, schools, and hospitals). National and local governments have successively introduced strict noise emission standards, especially for substations located near residential areas, where noise levels must comply with relevant standards.

[0003] Therefore, developing a sound insulation device that can effectively reduce reactor operating noise, meet environmental protection requirements, and ensure equipment operating safety has become an urgent technical problem to be solved in the power industry. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-efficiency sound-absorbing and noise-reducing substation reactor soundproof cover, which solves the problem of excessive noise during reactor operation in traditional technologies.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-efficiency sound-absorbing and noise-reducing substation reactor soundproof cover, comprising a bottom support frame, columns, middle partition, outer soundproof panel and top cover; The bottom support frame serves as the foundation of the soundproof cover. There are multiple columns, all welded to the bottom support frame and spaced along the edge of the bottom support frame to form a support frame around the soundproof cover. The outer soundproof panels are fixedly installed between adjacent columns to form the outer wall structure of the soundproof cover. The top cover is set on top of the columns. The middle partition is connected to the inner wall of the soundproof enclosure, dividing the interior of the soundproof enclosure into two parts: an electrical room and a soundproof room. The middle partition includes protective layers on both sides and a sound-absorbing cotton layer and a sound-insulating board layer in the middle.

[0006] Furthermore, the protective layers on both sides of the middle partition are respectively attached to the sides of the sound-absorbing cotton layer and the sound-insulating board layer, and the layers are fixed together with adhesive. The protective layer is a galvanized sheet with a primer; the sound-absorbing cotton layer is basalt sound-absorbing cotton; the sound insulation board layer is a damping sound insulation felt. The structure of the outer sound insulation panel is the same as that of the middle partition.

[0007] Furthermore, an electrical cabinet is installed in the electrical room, and the electrical cabinet is connected to the reactor; the reactor is installed in the soundproof room; the electrical cabinet and the reactor are connected by a cable. The intermediate partition is provided with cable holes for cables to pass through and connect the electrical cabinet and the reactor. A silicone fireproof sealing sleeve is provided inside the cable holes.

[0008] Furthermore, the top cover is also covered with flow-guiding tiles; a layer of rock wool is provided between the flow-guiding tiles and the top cover.

[0009] Furthermore, the top cover is provided with multiple lifting points, which are evenly distributed along the edge of the top cover for the hoisting, transportation and installation of the soundproof cover.

[0012] Beneficial effects This utility model of a high-efficiency sound-absorbing and noise-reducing substation reactor soundproof cover has significant advantages in high-efficiency sound absorption and noise reduction through reasonable structural design and material selection. The middle partition and outer sound insulation panels of this utility model both adopt a composite structure design of protective layers on both sides, a sound-absorbing cotton layer in the middle, and a sound insulation panel. The sound-absorbing cotton layer uses basalt sound-absorbing cotton, which has high porosity and good air permeability, effectively absorbing the mid-to-high frequency noise generated during reactor operation and reducing noise reflection and superposition inside the sound insulation enclosure. The sound insulation panel layer uses damping sound insulation felt, which has excellent sound insulation performance and damping vibration reduction effect, effectively blocking the propagation of low-frequency noise and preventing noise from penetrating the sound insulation panel and leaking outwards.
