Description

Technical Field

[0001] The utility model relates to the technical field of dry-type reactors, in particular to a sound insulation cover for a dry-type air-core reactor. Background Art

[0002] At present, the noise of dry-type air-core reactors in substations is sometimes very loud due to special conditions, affecting the surrounding environment. When the operating voltage is relatively high, the dry-type reactor needs to be equipped with a rain-proof and noise-reducing device to ensure stable operation in a harsh environment. However, after the existing dry-type air-core reactors are rain-proof and noise-reducing, the heat dissipation performance of the reactors will generally decrease.

[0003] In order to ensure the heat dissipation of the reactor, a certain gap generally needs to be maintained between the upper sound insulation cover and the upper end of the reactor. Therefore, birds and the like can easily enter through this gap to build nests on the upper part, and the formed bird droppings, sundries, etc. fall into the air duct of the coil to form a fault point. In the existing reactors, for example, in the patent document with the application number 201520624534.1 and the name of Side Anti-bird Fence for Dry-type Reactor, when setting the anti-bird grille outside, it is all set at the gap between the sound insulation cover and the reactor, which is not easy to install. And when a bird lands on the lower part of the reactor and enters from the reactor base, it cannot be protected either. Therefore, there is an urgent need for a sound insulation cover for a dry-type air-core reactor. Summary of the Utility Model

[0004] Therefore, the purpose of the utility model is to provide a sound insulation cover for a dry-type air-core reactor. By setting two protection plates and an insulating base at the bottom, it can not only ensure the heat dissipation of the reactor but also achieve the overall protection of the reactor, preventing birds and other small animals from entering the sound insulation cover from the upper or lower part.

[0005] In order to achieve the above purpose, a sound insulation cover for a dry-type air-core reactor provided by the utility model includes a hemispherical upper cover, a protection sleeve, a first protection fence, and a second protection fence. Ventilation openings are provided on the hemispherical upper cover; the hemispherical upper cover is fixedly connected to the protection sleeve below, and a dry-type air-core reactor is placed inside the protection sleeve.

[0006] The first protection fence includes a hollow column and a plurality of protection plates; slots are provided around the hollow column, and each protection plate is inserted into the corresponding slot; the first protection fence is arranged on the upper part of the dry-type air-core reactor.

[0007] The second protection fence includes a first protection fence, a first bracket, and a second bracket; the first bracket is sleeved outside the second bracket and is coaxial with the first bracket; the first protection fence is fixedly installed below the first bracket and the second bracket, and the second protection fence is fixedly connected to the side wall of the protection sleeve.

[0008] Further, preferably, the second bracket is composed of a plurality of hollow annular arc plates spliced together.

A vent 6 is opened on the hemispherical upper cover 1; the lower part of the hemispherical upper cover 1 is fixedly connected to the protective sleeve 2, and a dry-type air-core reactor 7 is placed inside the protective sleeve 2; in this application, protective fences are provided both on the upper and lower parts of the protective sleeve to prevent birds from entering the dry-type air-core reactor from above or below.

[0027] As Figure 3 shown, the first protective fence 4 includes a hollow column 401 and a plurality of protective plates 402; slots 403 are provided around the hollow column 401, and each protective plate 402 is inserted into the corresponding slot 403; the first protective fence 4 is arranged on the upper part of the dry-type air-core reactor 7. By using the hemispherical upper cover, water accumulation on the top during rain is reduced. At the same time, a protective sleeve 2 is sleeved outside the dry-type air-core reactor 7, and the protective sleeve 2 is coated with a sound insulation material or sound insulation cotton is laid to achieve rain protection and sound insulation.

[0030] Furthermore, grooves are provided at positions on each protective plate 402 that are at the same distance from the hollow column 401. The grooves form an annular array for placing a protective net. After the protective net is set, it can prevent catkins and fallen leaves from falling in during spring and autumn, thereby extending the service life of the reactor.

[0031] As Figure 5-6 shown, a plurality of insulating bases are provided below both the protective sleeve 2 and the second bracket.
