Detailed Description
In order to further describe the technical means and effects adopted by the invention for achieving the preset aim, the following detailed description is given below of the specific implementation, structure, characteristics and effects according to the invention with reference to the attached drawings and the preferred embodiment.
Referring to fig. 1-4, the embodiment provides a vertical landscape substation, which comprises a landscape cabinet 1, a transformer 2, a high-voltage device 3 and a low-voltage device 4, wherein two screen clapboards 11 are arranged in the landscape cabinet 1, one screen clapboards 11 are positioned at one third of the vertical direction of the landscape cabinet 1 to divide the landscape cabinet 1 into a first independent compartment and a second independent compartment, the second independent compartment is positioned at the right of the landscape cabinet 1 and occupies two thirds of the whole landscape cabinet 1, the other screen clapboards 11 are positioned at the middle of the second independent compartment to divide the second independent compartment into two spaces with the same size, the high-voltage device 3 is arranged in the first independent compartment, the transformer 2 and the low-voltage device 4 are both positioned in the second independent compartment and above the low-voltage device 4, one side of the transformer 2 is connected with the high-voltage device 3, and the other side of the transformer 2 is connected with the low-voltage device 4. In this process, the voltage change occurs between the high-voltage side and the low-voltage side, so in the design and manufacture of the transformer 2, the terminals are usually arranged on the two sides of the transformer 2, so as to facilitate wiring and use, and in general, the occupation space proportion of the high-voltage equipment 3 is about 1:3, so that the installation requirement of the high-voltage equipment 3 is met by installing the high-voltage equipment 3 in the first independent compartment, the installation space of the transformer 2 can be reserved to facilitate the installation of the transformer 2, the transformer 2 is installed above the second independent compartment, so that the connection of the transformer 2 with the high-voltage equipment 3 and the low-voltage equipment 4 is more convenient, the mesh partition 11 meets the IP33 level requirement, and the mesh partition 11 meeting the IP33 level requirement can protect the electric safety and realize air flow at the same time, thereby not only playing a role in protecting the transformer 2, the high-voltage equipment 3 and the low-voltage equipment 4, but also playing the role in separating the inside the cabinet 1, reducing the distance of the cable cabinet, reducing the production cost, reducing the electric energy consumption of the whole landscape space, and reducing the occupied area by 1.
In order to reduce the loss of the low-voltage equipment 4 and improve the service life of the low-voltage equipment 4, the screen separator 11 between the low-voltage equipment 4 and the transformer 2 can adopt a sealing plate as a separation plate between two compartments, because the transformer 2 can emit a large amount of heat to the periphery, in order to avoid heat accumulation caused by untimely emission, the low-voltage equipment 4 is in a high-temperature environment for a long time, and the service life of the low-voltage equipment 4 is influenced, therefore, the screen separator 11 between the low-voltage equipment 4 and the transformer 2 adopts a sealing plate as separation, the low-voltage equipment 4 can be effectively prevented from being influenced by the heat of the transformer 2, and when the vertical landscape transformer station dissipates heat, cold air enters into the compartments of the high-voltage equipment 3 and the low-voltage equipment 4 from the bottom, the air entering into the compartments of the first independent compartments flows out from the louver at the tops of the compartments and enters into the first independent compartments of the transformer 2, and the air entering into the compartments of the low-voltage equipment 4 can enter into the first independent compartments of the high-voltage equipment 3, so that the heat of the transformer 2 enters into the low-voltage equipment 4 into the first independent compartments of the low-voltage equipment 4, and the low-voltage equipment 4 cannot be prevented from being corroded by the low-voltage equipment 4, and the low-voltage equipment 4 can not enter into the compartments 2 through the vertical landscape transformer 4, and the low-voltage equipment 2 can not be prevented from being corroded by the low-voltage equipment 4, and the top equipment 2.
The box-type transformer substation is suitable for residential communities, urban public transformer, busy cities, construction power supplies and the like, and a user can select the box-type transformer according to different using conditions and load grades. Since the advent of box-type substations, the development has been extremely rapid, accounting for 70% of distribution transformer 2 in developed countries in europe and 90% of distribution transformer 2 in the united states. Along with the rapid development of modern construction of China cities, urban distribution networks are updated and transformed continuously, and box-type substations are required to be widely applied in the future.
The box-type substation generally includes a housing, high-voltage switching equipment, a distribution transformer 2, and a low-voltage distribution device installed in the housing. The shell is usually made of steel plates or alloy plates, is provided with a double-layer top cover, and has good heat insulation. The shell and the framework are all subjected to corrosion prevention treatment, and the long-term outdoor use condition is achieved. The high-voltage switch equipment, the distribution transformer and the low-voltage distribution device are prefabricated in a factory according to a certain wiring scheme, and are convenient to install on site. However, the existing box-type substation has the following problems:
because the European box transformer is formed by arranging the transformer 2 and common high-voltage electrical equipment in the same metal shell box body, the transformer 2 is high in room temperature, heat dissipation difficulty is caused, and meanwhile, heat radiates the high-voltage switching equipment and the low-voltage power distribution device, ageing acceleration of components is easily caused, so that the service life of a product is influenced, and more importantly, the operation safety of the product is influenced.
The high-voltage switch equipment, the distribution transformer and the low-voltage distribution device are arranged in the box body according to a certain wiring scheme, a common high-voltage load switch, a fuse and a low-voltage switch cabinet are generally adopted, and enough electricity safety distance needs to be ensured, so that the European box body is large in volume and generally reaches 6-12 square meters, and therefore, a quite large occupied area is occupied, and for modern cities with the size of earth and gold, significant cost pressure and city aesthetic planning difficulty are brought, and as cooling fins are generally added to the periphery of the transformer 2 to help the transformer 2 dissipate heat, the loss of the transformer 2 is in direct proportion to the volume of the transformer 2, and when the transformer 2 needs to increase power, a larger cooling area is also needed to complete heat dissipation, so that the volume of the transformer 2 is greatly increased.
With the continuous improvement of life quality, the electric equipment is continuously enriched and used, so that the electricity consumption of residents is greatly improved, and particularly in some old urban areas, the original configuration load can not meet the normal electricity consumption requirement far, and the improvement and the capacity increase of electricity consumption distribution facilities are required; therefore, the capacity of an electric room or a box transformer substation of the original equipment power distribution facility needs to be expanded, and as the original electric room used in the old urban area is configured by the current power load, the power distribution equipment added on the basis of the original space cannot meet the power safety requirement, the adopted box-type transformer substation is one of effective methods for solving the problem, and as various underground pipelines and lines of the old urban area are complex, the transformer substation is not suitable for being buried; even if the original distribution facilities in the original old urban area are box-type substations, the volume of the box-type substation needs to be greatly increased because the occupied area of the original transformer station is too small and the transformer station needs to be increased in capacity when being transformed; the old urban planning is also fixed, and no method is available to occupy other residential areas to complete capacity increment of the transformer station, and the old transformer station cannot meet the urban electricity demand after transformation, so that the requirement of pressurizing the transformer station is required to be completed in a limited occupied area.
This scheme adopts screen cloth baffle 11 to divide into three compartment with view cabinet 1, lets transformer 2 be in the top of the independent compartment of second that is right side of view cabinet 1 upper position, simultaneously, in order to reduce because the condition that the volume grow when transformer 2 increases power, can adopt a liquid insulation transformer heat radiation structure of publication number CN215417802U, includes: a transformer and a self-driven radiator; the self-driven radiator consists of an aluminum profile and a sealing metal heat conduction pipe, wherein the sealing metal heat conduction pipe is a hollow conduit with two closed ends, and a refrigerant is injected into a sealing pipe cavity of the sealing metal heat conduction pipe when the sealing pipe cavity is in a vacuum state; the aluminum profile is located above the transformer, the central through hole of the aluminum profile is in interference fit with the upper end part of the sealing metal heat conduction pipe, the middle part of the sealing metal heat conduction pipe is fixed on the top surface of the shell of the transformer through a sealing installation structure, the lower end part of the sealing metal heat conduction pipe stretches into insulating liquid of the transformer, and the lower end part of the sealing metal heat conduction pipe is located above an iron core winding of the transformer.
