Description

Technical Field

[0001] The utility model relates to the technical field of transformer substations, in particular to a ventilation and air exchange structure of a box-type transformer substation. Background Art

[0002] The box-type substation, also known as the prefabricated substation or prefabricated substation, is a compact complete distribution device that combines high-voltage switchgear distribution transformers, low-voltage switchgear, electric energy metering equipment and reactive power compensation devices in one or several boxes according to a certain wiring scheme. It is widely used in mines, factories, enterprises, oil and gas fields, wind power stations and other fields because of its easy construction and no geographical restrictions.

[0003] Box-type substations are usually built outdoors. In summer, the internal temperature is high due to exposure to the sun. In addition, when the substation is working, it will also generate a lot of heat. If this continues for a long time, the equipment may be damaged. In addition, on rainy days or in an environment with a large temperature difference between indoor and outdoor, the inside of the substation will be relatively humid. If it is not ventilated in time, it may also cause damage to the equipment. Therefore, it is necessary to equip the box-type substation with a set of ventilation structures. Utility Model Content

[0004] In view of this, the utility model provides a box-type substation ventilation structure to meet the technical requirements proposed by the background technology.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A box-type substation ventilation structure includes a substation body, characterized in that: a roof cover assembly is fixedly installed on the top of the substation body through a beam support frame, the circumferential edge of the roof cover assembly extends outwardly beyond the beam support frame, and the beam support frame is provided with air holes in a circumferential array, and the air holes connect the inside of the substation body with the outside; a shutter assembly is provided in the circumference of the substation body, and the shutter assembly is used for ventilation.

[0007] By adopting the above structure, the shutter components and the hollow structure of the beam support frame can facilitate the heat inside the substation to dissipate outwards, while also realizing the flow of gas, thereby achieving the purpose of ventilation.

[0008] Preferably, an exhaust groove is provided on the top circumference of the substation body, and the beam support frame is connected to the outer end of the substation body through the exhaust groove. With the above structure, the gas inside the substation can be discharged to the outside.

[0009] As a preferred embodiment, the beam support frame is assembled from beam rods, and any adjacent beam rods are connected by reinforcing plates. The above structure ensures that the beam support frame structure is more stable.

[0010] Preferably, the upper and lower sides of the front and rear ends of the substation body are provided with shutter assemblies, and the substation body is provided with an exhaust assembly inside, which allows air to enter from the shutter assembly on the lower side of the substation body and then be exhausted from the shutter assembly on the upper side of the substation body. With the above structure, the exchange of gas inside and outside the substation is achieved through the exhaust assembly.

[0011] As a preferred embodiment, the lower sides of the left and right ends of the substation body are both provided with shutter components. With the above structure, the substation body has better air permeability.

[0012] Preferably, the bottom end of the roof cover assembly abuts against the upper end surface of the exhaust groove, so that a closed space is formed between the roof cover assembly and the exhaust groove. The above structure can ensure that the main body of the substation has good airtightness, and air exchange can only be carried out through the exhaust groove and the shutter assembly.

[0013] Preferably, the roof cover assembly is provided with strip holes in an array. The above structure can facilitate gas flow.

[0014] Preferably, the reinforcing plate is a right-angled triangle structure, and the two right-angled sides are folded to form folded parts, and the folded parts are provided with mounting holes. The above structure can ensure that any two beams are more firmly installed.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The ventilation and air exchange structure of the box-type substation provided by the utility model ensures the flow of air inside and outside the substation through the hollow structure of the beam support frame and the shutter assembly, thereby realizing the ventilation and air exchange of the box-type substation and preventing mosquitoes from entering.

[0017] 2. The exhaust components are installed to speed up the air flow and ventilation efficiency, thereby ensuring the ventilation function of the box-type substation. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The utility model is further described below in conjunction with embodiments and drawings.

[0028] like Figure 1 and Figure 2 As shown, a box-type substation ventilation structure includes a substation body A, on the top of which a roof cover assembly 6 is fixedly installed through a beam support frame 1. In this embodiment, the circumferential edge of the roof cover assembly 6 extends outward beyond the beam support frame 1. The beam support frame 1 is a hollow structure, and air holes 1a are arranged in a circumferential array on the beam support frame 1. The air holes 1a can connect the inside of the substation body A with the outside. A shutter assembly 2 is also installed around the substation body A, and the shutter assembly 2 is also used for ventilation.

[0029] With such a design, the hollow structure of the beam support frame 1 and the shutter assembly 2 enable the air inside and outside the box-type substation to be exchanged, thereby ensuring that the temperature and humidity inside the substation body A are appropriate.

[0030] For example Figure 2 As shown, an exhaust groove 3 is installed circumferentially on the top of the substation body A, and the beam support frame 1 exchanges gas with the outside through the exhaust groove 3 at the circumferential edge of the substation body A.

[0031] Specifically, Figure 3 and Figure 5 As shown, the bottom end of the roof cover assembly 6 abuts against the upper end surface of the exhaust groove 3, so that a closed space is formed between the roof cover assembly 6 and the exhaust groove 3, thereby ensuring that the internal gas of the substation body A can only be discharged through the exhaust groove 3 after coming out of the beam support frame 1.

[0032] There are also strip holes 3 a arranged in an array at the bottom of the exhaust groove 3 to ensure that the exhaust groove 3 can smoothly exchange gas. Furthermore, the strip holes 3 a are arranged at the bottom of the exhaust groove 3 to prevent mosquitoes from entering.

[0033] Combination Figure 4 As shown, the air inside the transformer substation body A can flow into the exhaust slot 3 through the air holes 1a on the beam support frame 1 in the direction indicated by the arrow, and be discharged through the strip holes 3a.

[0034] like Figure 7 and Figure 8 As shown, in this embodiment, the roof cover assembly 6 includes a mounting frame 6a and three roof cover panels 6b installed inside the mounting frame 6a. A condensate channel 6a1 is formed on the bottom surface of the mounting frame 6a along the length direction. The condensate channel 6a1 is used to discharge the condensate inside the substation body A. The condensate inside the substation body A passes through the condensate channel 6a1 and can eventually flow into the exhaust groove 3, thereby further ensuring the dryness inside the substation body A.

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, the beam support frame 1 is formed by splicing ten beam rods 1b, and any two adjacent beam rods 1b are connected by a reinforcing plate 4.

[0036] like Figure 6 As shown, the reinforcing plate 4 is a right-angled triangular plate, and both right-angled sides are folded with folded portions 4a, and mounting holes 4b are also formed on the folded portions 4a. In this embodiment, the installation between the two beams 1b is achieved by installing bolts between the mounting holes 4b and the air holes 1a.

[0037] like Figure 1 and Fig. 9 As shown, shutter assemblies 2 are installed on both upper and lower sides of the front and rear ends of the transformer substation body A, and exhaust assemblies 5 are installed at positions corresponding to the upper shutter assemblies 2 in the transformer substation body A. The exhaust assemblies 5 can allow air to enter from the shutter assemblies 2 on the lower side of the transformer substation body A and then be discharged from the shutter assemblies 2 on the upper side of the transformer substation body A. In this embodiment, the exhaust assemblies 5 are exhaust fans.

[0038] In addition, shutter assemblies 2 are also installed on the lower sides of the left and right ends of the substation body A, so as to ensure that the substation body A has better ventilation function.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
