Description

Technical Field

[0001] The utility model belongs to the technical field of power control, in particular to a pre-installed transformer substation. Background Art

[0002] Substation refers to the place in the power system where voltage and current are transformed, electric energy is received and distributed. The substation in the power plant is a step-up substation, which boosts the electric energy generated by the generator and feeds it to the high-voltage power grid. Among them, the prefabricated substation is a factory-prefabricated indoor and outdoor compact distribution equipment that is arranged in a certain wiring scheme and integrates high-voltage switchgear, distribution transformers and low-voltage distribution devices. It combines the functions of transformer step-down and low-voltage distribution organically and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed, movable steel structure box. It is suitable for residential areas, mines, factories and enterprises, oil and gas fields and wind power stations. However, it still has the following disadvantages in actual use:

[0003] The utility model with publication number CN216720753U discloses an outdoor prefabricated substation, wherein a directional wheel is fixedly installed at the lower end of the substation, a universal wheel is fixedly installed at the lower end of the substation and at the end away from the directional wheel, a concave box is fixedly installed at the middle part of the lower end of the substation, and a circular groove is penetrated through the front end of the lower end of the concave box. The prefabricated substation is easy to move during installation and transportation through the universal wheel, which improves the convenience of installation. However, due to the structure of the universal wheel, the prefabricated substation needs a certain time to perform positioning operation after moving to the installation position to ensure the stability of the substation when in use, and the operation is relatively cumbersome;

[0004] In order to ensure the normal operation of the prefabricated substation, it is usually necessary to use a fan to drive the air circulation inside and outside the substation to avoid damage to components due to excessive temperature in the substation. However, when using air cooling to dissipate heat, it is necessary to consider whether external dust will enter the substation, and it is also necessary to consider the humidity of the external air to avoid rust on the components due to excessive air humidity. As a result, the prefabricated substation needs to install and use multiple structures, which increases costs and maintenance expenses. Utility Model Content

[0005] The purpose of the utility model is to provide a prefabricated substation. Through the substation box, universal wheels and heat-conducting rods, the prefabricated substation is transported by universal wheels, but the substation needs to be positioned between the environment and multiple structures after being moved to the installation position, and the operation is relatively cumbersome. The substation needs to use multiple structures to dissipate heat and protect components, which increases costs and maintenance expenses.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a prefabricated substation, comprising a substation box, universal wheels and heat-conducting rods. A heat dissipation fan is arranged in the substation box, universal wheels are arranged around the bottom of the substation box, and a lifting cylinder is arranged on the top of each universal wheel. A plurality of heat-conducting rods are inserted through the bottom of the inner edge of the substation box, and a positioning cone is welded and fixed at the bottom of each heat-conducting rod.

[0008] The heat dissipation fan drives the air to circulate in the substation box, so that the airflow drives the heat on the surface of the component to the surface of the heat-conducting rod, and dissipates the heat through the heat-conducting rod, so that the substation box is relatively closed, and the state inside the substation box is prevented from being affected by the outside world, the device structure is simplified, and the cost and maintenance expenses are reduced. When the prefabricated substation is transported, the convenience of moving the substation box is improved by the universal wheels. After the substation box is moved to the installation position, the universal wheels are retracted by the lifting cylinder, so that the substation box can be moved downward, and the cone is further inserted into the preset hole or soil. The substation box is positioned by multiple cones to ensure the stability of the substation box. The operation is simple and convenient, and the installation difficulty is reduced.

[0009] Furthermore, a maintenance cover is rotatably connected to one side of the substation box, storage slots are provided around the bottom of the substation box, a partition is welded and fixed in the center of the substation box, and the heat dissipation fan is connected to one side of the partition through the card;

[0010] By opening the maintenance cover, components can be installed in the substation box, or components in the substation box can be replaced or maintained. The universal wheels can be stored through the storage slot when the substation box does not need to be moved, thereby ensuring the stability of the substation box.

[0011] Furthermore, a top plate is welded and fixed on the top of the substation box, a circulation chamber is opened on the top of the substation box, a vent is opened through the bottom of the circulation chamber, and the vent is located on both sides of the partition;

[0012] The space inside the substation box can be divided by partitions and circulation rooms. When the heat dissipation fan drives the air flow inside the substation box, the air enters the circulation room through the vents on one side of the substation box, and then enters the other side of the substation box through the vents, so that the air circulates inside the substation box, blows out the heat on the surface of the components, and exchanges heat through the heat-conducting rods to transfer the heat to the soil, making the substation box relatively closed, preventing the state inside the substation box from being affected by the outside world, simplifying the device structure, and reducing costs and maintenance expenses.

[0013] Furthermore, a telescopic tube is slidably connected to the bottom of each lifting cylinder, the universal wheel is rotatably connected to the bottom of the telescopic tube, and the lifting cylinder is connected to the top of the storage slot;

[0014] The lifting cylinder can further drive the up and down movement of the universal wheel by driving the extension and retraction of the telescopic tube. When the prefabricated substation needs to be moved, the universal wheel can be moved downward to fit the ground, thereby improving the convenience of movement. When there is a large amount of water on the ground due to floods and other disasters, the substation box can also be lifted by controlling the downward movement of the universal wheel to prevent the substation box from being immersed in water.

[0015] Furthermore, a first heat-conducting fin is welded and fixed to the outer circumference of the heat-conducting rod, a second heat-conducting fin is welded and fixed to the outer circumference of the positioning cone, and the first heat-conducting fin is located inside the transformer substation box;

[0016] When the substation box is installed and positioned, when the universal wheel is stored, the substation box moves downward, so that the positioning cone is inserted into the preset hole or soil under pressure, and the substation box is positioned to ensure the stability of the substation box. The operation is simple and convenient, and the installation difficulty is reduced. When the components are dissipating heat, the first heat-conducting fins increase the heat-conducting area of ​​the heat-conducting rod, and the second heat-conducting fins increase the heat-conducting area of ​​the positioning cone, so that the heat in the substation box can be quickly discharged into the soil, ensuring the heat dissipation efficiency.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problem that the prefabricated substation is easy to move during installation and transportation through the universal wheels by arranging a substation box, universal wheels and heat-conducting rods, thereby improving the convenience of installation. However, due to the structures such as the universal wheels, the prefabricated substation needs a certain amount of time to perform positioning operations after being moved to the installation position to ensure the stability of the substation during use, and the operation is relatively cumbersome. After the substation box is driven to move to the installation position by the universal wheels, the lifting cylinder is controlled to drive the universal wheels to move upward to store the universal wheels, and at the same time the substation box is moved downward until the positioning cone is inserted into the preset hole or soil, the substation box is positioned, the stability of the substation box is ensured, the operation is simple and convenient, and the installation difficulty is reduced.

[0019] The utility model solves the problem that, in order to ensure the normal operation of the prefabricated substation, a fan is usually needed to drive the circulation of air inside and outside the substation to avoid damage to components due to excessive temperature in the substation by arranging a substation box and universal wheels. However, heat dissipation through air cooling needs to consider whether external dust and the like will enter the substation, and also needs to consider the humidity of the external air to avoid rusting of components due to excessive air humidity, resulting in the need to install and use multiple structures in the prefabricated substation, which increases costs and maintenance expenses. When the temperature in the substation box is high, the heat dissipation fan drives the air in the substation box to circulate, and the flowing air takes away the heat on the surface of the components and contacts with the heat conducting rods for heat exchange, and transfers the heat to the soil through the heat conducting rods, further cooling the substation box and the components, making the substation box relatively airtight, avoiding the state in the substation box from being affected by the outside world, simplifying the device structure, and reducing costs and maintenance expenses.

[0029] The transformer substation box 1 is moved to the installation position by the universal wheel 2, and the lifting cylinder 202 is controlled to drive the universal wheel 2 to move upward, and further drive the transformer substation box 1 to move downward, so that the positioning cone 301 is inserted into the preset hole or soil, and the prefabricated transformer substation is positioned.
