The fan assembly is communicated with the heat dissipation air duct. When the fan assembly operates, it can drive the air to flow through the transformer in the heat dissipation air duct to dissipate heat from the transformer by air cooling.

[0008] Specifically, by arranging a baffle in the transformer cabinet, the baffle can enclose and form a heat dissipation air duct, and the baffle can enclose around the transformer. The formed air duct has good sealing performance around the transformer, avoiding air leakage around the transformer and improving the heat dissipation performance of the transformer cabinet.

[0009] In this technical solution, the fan assembly draws power from within the transformer cabinet through a power supply cable. A crossbeam is also provided within the transformer cabinet. The crossbeam is disposed within the accommodation cavity, and a wire trough is provided on the crossbeam. The wire trough can accommodate and hold the power supply cable within the transformer cabinet. Through the wire trough on the crossbeam, the cables of the fan assembly can be uniformly organized and stored, facilitating the installation and subsequent maintenance of the transformer cabinet.

[0010] Specifically, when installing the transformer cabinet, the transformer is fixedly installed within the heat dissipation air duct formed by enclosing with a fence, and a certain gap is left between the transformer and the fence. The fan assembly is installed on the top of the cabinet body, and the power supply cable of the fan assembly penetrates through the top of the cabinet body and extends into the accommodation cavity. The part of the power supply cable extending into the accommodation cavity is arranged within the wire trough.

[0011] In the technical solution of this application, by providing a fence within the transformer cabinet, the fence encloses the periphery of the transformer to form a heat dissipation air duct. The heat dissipation air duct formed by enclosing with the fence has good sealing performance around the transformer, avoiding the reduction of heat dissipation performance caused by air leakage around the transformer. And a crossbeam with a wire trough is provided within the transformer cabinet. The wire trough of the crossbeam can accommodate the power supply cable of the fan assembly, making the fan wiring socket visible and easy to operate. That is, the wire trough provides an operating space for the installation and maintenance process of the power supply cable of the fan assembly, facilitating the installation of the fan assembly on the cabinet body and also facilitating the subsequent maintenance of the power supply cable of the fan assembly in the transformer cabinet.

[0012] In some technical solutions, optionally, one end of the crossbeam is connected to the first sidewall of the cabinet body, and the other end of the crossbeam is connected to the second sidewall of the cabinet body: first openings are provided on both the first sidewall and the second sidewall of the cabinet body, and the first openings are in communication with the wire trough.

[0013] In this technical solution, both ends of the crossbeam are fixedly connected to the first sidewall and the second sidewall of the cabinet body respectively, where the first sidewall and the second sidewall are two relatively arranged sidewalls of the cabinet body. First openings are provided on both the first sidewall and the second sidewall, and the first openings are in communication with the wire trough. The first openings communicate the wire trough with the outside of the cabinet body, enabling installers and maintenance personnel to install and maintain the power supply cable within the wire trough through the first openings.

[0014] In the technical solution of this application, by providing first openings on the opposite first sidewall and second sidewall of the cabinet body, both ends of the crossbeam are fixedly connected to the first sidewall and the second sidewall respectively. The first openings serve as maintenance windows for the power supply cable within the wire trough and are in communication with the wire trough, enabling installers and maintenance personnel to repair the power supply cable within the wire trough through the first openings.

[0015] In some technical solutions, optionally, the fan assembly is located at the top of the cabinet body, the cross beam and the enclosure are arranged adjacent to each other in the first direction, and the cross beam is located between the enclosure and the fan assembly.

[0016] In this technical solution, the fan assembly is fixedly installed at the top of the cabinet body. The heat dissipation air duct formed by the enclosure extends from the top to the bottom of the cabinet body. The fan assembly can drive the air to flow in the heat dissipation air duct, so that the air flows through the transformer in the heat dissipation air duct. The cross beam is arranged between the enclosure and the fan assembly. The power supply cable of the fan assembly can extend from the top of the cabinet body to the accommodation cavity. Since the cross beam is arranged between the enclosure and the fan assembly, after the power supply cable enters the accommodation cavity, it can be stored in the wire groove, improving the storage effect of the wire groove on the power supply cable.

[0017] In the technical solution of the present application, by arranging the fan assembly at the top of the cabinet body, it is convenient for the installation and maintenance of the fan assembly, and by arranging the cross beam with a wire groove between the fan assembly and the enclosure, it is convenient to lay the power supply cable of the fan assembly in the wire groove, further improving the convenience of installing the fan assembly.

[0018] In some technical solutions, optionally, the enclosure includes: a first baffle; a second baffle, which is arranged opposite to the first baffle. Both the first baffle and the second baffle include notches, and the notches are used to avoid the cross beam so that at least part of the cross beam is accommodated in the heat dissipation air duct.

[0019] In this technical solution, the enclosure includes a first baffle and a second baffle arranged opposite to each other. Notches for avoiding the cross beam are provided on the first baffle and the second baffle. The cross beam passes through the first baffle and the second baffle through the notches and is connected to the side wall of the cabinet body. At least part of the cross beam is located in the heat dissipation air duct, making the internal structure installation of the transformer cabinet more compact and avoiding the cross beam and the enclosure occupying a large amount of space.

[0020] Specifically, the cabinet body includes a first side wall and a second side wall arranged opposite to each other. The first baffle is fixedly connected to the first side wall, the second baffle is fixedly connected to the second side wall, both ends of the cross beam are fixedly connected to the first side wall and the second side wall, notches are formed on the first baffle and the second baffle, and at least part of the cross beam passes through the notches of the first baffle and the second baffle and is fixedly connected to the first side wall and the second side wall.

[0021] It should be noted that the wire groove in the cross beam stores the power supply cable of the fan assembly. During the operation of the fan assembly, the power supply cable generates heat. The cross beam passes through the first baffle and the second baffle through the notch, and at least part of the cross beam is located in the heat dissipation channel. The air flow in the heat dissipation channel can dissipate heat from the power supply cable in the wire groove.

[0022] In the technical solution of the present application, by opening notches on the first baffle and the second baffle which are oppositely arranged in the enclosure, the cross beam can pass through the enclosure through the notches and be connected to the cabinet body, and at least part of the cross beam can be located in the heat dissipation air duct. This can not only save the occupied space of the cross beam and the enclosure in the accommodation cavity, but also enable the heat dissipation air duct to have a certain heat dissipation effect on the power supply cables accommodated in the wire trough.

[0023] In some technical solutions, optionally, the notches are located on the first side of the first baffle and the second baffle, and the first side is the side where the first baffle and the second baffle are close to the fan assembly.

[0024] In this technical solution, the notches are opened on the first side of the first baffle and the second baffle close to the fan assembly. Since the cross beam passes through the notches, the cross beam can be close to the first side of the first baffle and the second baffle. Specifically, the fan assembly is arranged on the top of the cabinet body, so the first side of the first baffle and the second baffle is the upper side of the enclosure.

[0025] In this technical solution, by opening the notches on the first side of the first baffle and the second baffle close to the fan assembly, the cross beam passing through the notches is closer to the fan assembly, so that the wire trough in the cross beam is closer to the fan assembly, further improving the convenience of laying the power supply cables of the fan assembly in the wire trough when the fan assembly is installed on the cabinet body.

[0026] In some technical solutions, optionally, a second opening is opened on the enclosure, and a third opening is opened on the cabinet body, wherein the third opening and the second opening are oppositely arranged in the second direction.

[0027] In this technical solution, a second opening is opened on the enclosure, and a third opening is arranged on the cabinet body. The third opening and the second opening are oppositely arranged, so that the second opening and the third opening are connected. Since the opening position of the second opening corresponds to the installation position of the transformer, the staff can overhaul the transformer in the transformer cabinet through the second opening and the third opening.

[0028] Specifically, an installation seat for the transformer is arranged on the inner side wall of the enclosure, the transformer is fixedly installed on the installation seat, and the opening positions of the second opening and the third opening correspond to the position of the installation seat. After the transformer is installed on the installation seat, the staff can contact the transformer through the second opening and the third opening to overhaul the transformer in the cabinet body.

[0029] In the technical solution of the present application, by opening a second opening on the enclosure and a third opening on the cabinet body that is connected to the second opening, and the opening directions of the second opening and the third opening both face the transformer, the staff can overhaul the transformer in the cabinet body without disassembling the cabinet body and the enclosure, further simplifying the operation steps of the staff for the transformer components.

[0030] In some technical solutions, optionally, the crossbeam includes: a bottom plate, on which a fan connector interface is provided, and the fan connector structure is used to connect the power supply cable; a bending part, connected to the bottom plate; wherein, the bending part and the bottom plate are integrally formed, and the bottom plate and the bending part enclose a wire routing groove.

[0031] In this technical solution, a fan connector interface is provided on the bottom plate, and this fan connector interface is arranged on the bottom plate, that is, this fan connector interface is located within the wire routing groove, enabling the power supply cable of the fan assembly to pass through this fan connector interface to be connected to the power supply, and facilitating the staff to lay the power supply cable within the wire routing groove.

[0032] In the technical solution of the present application, the crossbeam includes a bottom plate and a bending part provided on the bottom plate. The bending part is integrally formed with the bottom plate, which improves the connection stability between the bending part and the bottom plate and simplifies the production process of the crossbeam.

[0033] In some technical solutions, optionally, a wiring port is provided at the top of the cabinet body; and / or a wiring terminal is provided at the top of the cabinet body.

[0034] In the technical solution of the present application, a wiring port is provided at the top of the cabinet body, and this wiring port is used to electrically connect the equipment within the cabinet body to the equipment or electrical components in other transformer cabinets outside the transformer cabinet.

[0035] In the technical solution of the present application, a wiring terminal is provided at the top of the cabinet body, and this wiring terminal is used to electrically connect the equipment within the cabinet body to the equipment in other transformer cabinets outside the transformer cabinet. When electrically connecting to other transformer cabinets through the wiring terminal, the openings on the cabinet body can be reduced, improving the dust-proof performance of the electrical connection.

[0036] In some technical solutions, optionally, the fan assembly includes: a housing, arranged at the top of the cabinet body, and the inner cavity of the housing is communicated with the accommodation cavity; a dust-proof net, arranged on the housing; a fan, arranged within the housing.

[0037] In the technical solution of the present application, the fan assembly includes a housing for accommodating the fan. This housing is arranged on the top wall of the cabinet body, and a ventilation opening is provided on the bottom wall of the housing. This ventilation opening is communicated with the heat dissipation air duct formed by the enclosure within the cabinet body. The output end of the fan is oppositely arranged with the ventilation opening. During the operation of the fan, it can drive air to pass through the ventilation opening and the heat dissipation air duct to dissipate heat from the transformer within the heat dissipation air duct. The dust-proof net is arranged on the side wall of the housing. The dust-proof net can play a dust-proof role for the fan, preventing a large amount of dust from entering the fan, and the mesh structure of the dust-proof net can enable external air to enter the housing, improving the heat dissipation efficiency when the fan drives air to flow through the heat dissipation air duct.

[0038] In some technical solutions, the number of fan assemblies is at least two. At least two fan assemblies are all arranged on the top of the cabinet body, and at least two fan assemblies are arranged side by side in the third direction, where the third direction is the extending direction of the cross beam.

[0039] In the technical solution of the present application, multiple fan assemblies are arranged on the transformer cabinet, and the third direction of the arrangement of the multiple fan assemblies is the same as the extending direction of the cross beam, so that the multiple fan assemblies can be stably installed on the top of the cabinet body. When dissipating heat from the transformer, the fans in the multiple fan assemblies operate together, which can drive a larger air flow to flow through the transformer in the heat dissipation air duct, further improving the heat dissipation efficiency of the transformer.

[0076] Exemplarily, the first baffle 132 and the second baffle 134 are quadrilateral baffles, and the notch 136 is formed in the upper right corner of the first baffle 132 and the second baffle 134.

[0077] It should be noted that the wire groove 142 in the cross beam 140 houses the power supply cable of the fan assembly 120. During the operation of the fan assembly 120, the power supply cable generates heat. The cross beam 140 penetrates through the first baffle 132 and the second baffle 134 through the notch 136, and at least part of the cross beam 140 is located in the heat dissipation channel. The air flow in the heat dissipation channel can dissipate heat from the power supply cable in the wire groove 142.

[0078] In the embodiment of the present application, by opening the notch 136 on the first baffle 132 and the second baffle 134 that are oppositely arranged in the enclosure 130, the cross beam 140 can penetrate through the notch 136 to be connected to the cabinet body 110, and at least part of the cross beam 140 can be located in the heat dissipation air duct 131. This can not only save the occupied space of the cross beam 140 and the enclosure 130 in the accommodation cavity 112, but also enable the heat dissipation air duct 131 to have a certain heat dissipation effect on the power supply cable accommodated in the wire groove 142.

[0079] As Figure 1 、 Figure 2 and Figure 3 shown, in some embodiments, optionally, the notch 136 is located on the first side of the first baffle 132 and the second baffle 134, and the first side is the side of the first baffle 132 and the second baffle 134 close to the fan assembly 120.

[0080] In this embodiment, the notch 136 is opened on the first side of the first baffle 132 and the second baffle 134 close to the fan assembly 120. Since the cross beam 140 penetrates through the notch 136, the cross beam 140 can be close to the first side of the first baffle 132 and the second baffle 134. Specifically, the fan assembly 120 is arranged on the top of the cabinet body 110, so the first side of the first baffle 132 and the second baffle 134 is the upper side of the enclosure 130.

[0081] In this embodiment, the enclosure 130 further includes oppositely arranged third baffle 133 and fourth baffle 135. The first baffle 132, the second baffle 134, the third baffle 133 and the fourth baffle 135 enclose to form the heat dissipation air duct 131. Exemplarily, the cross section of the heat dissipation air duct 131 is quadrilateral.

[0082] In this embodiment, by opening the notch 136 on the first side of the first baffle 132 and the second baffle 134 close to the fan assembly 120, the cross beam 140 penetrating through the notch 136 is closer to the fan assembly 120, so that the wire groove 142 in the cross beam 140 is closer to the fan assembly 120, further improving the convenience of laying the power supply cable of the fan assembly 120 in the wire groove 142 when the fan assembly 120 is installed on the cabinet body 110.

[0083] As Figure 1 、Figure 2 and Figure 3 As shown in Figure 3 , in some embodiments, optionally, a second opening 138 is formed in the enclosure 130, and a third opening 114 is formed in the cabinet body 110, wherein the third opening 114 and the second opening 138 are oppositely arranged in the second direction.

[0084] Exemplarily, the second direction may be the width direction of the cabinet body 110 or the length direction of the cabinet body 110.

The second opening 138 is arranged on the right side wall of the enclosure 130, and the third opening 114 is arranged on the right side wall of the cabinet body 110, and the second opening 138 and the third opening 114 are oppositely arranged. In this embodiment, the second opening 138 is formed in the enclosure 130, and the third opening 114 is arranged on the cabinet body 110. The third opening 114 and the second opening 138 are oppositely arranged, so that the second opening 138 and the third opening 114 are communicated with each other. Since the opening position of the second opening 138 corresponds to the installation position of the transformer 150, the staff can overhaul the transformer 150 in the transformer cabinet 100 through the second opening 138 and the third opening 114.

[0085] Specifically, a mounting seat for the transformer 150 is arranged on the inner side wall of the enclosure 130. The transformer 150 is fixedly mounted on the mounting seat, and the opening positions of the second opening 138 and the third opening 114 correspond to the position of the mounting seat. After the transformer 150 is mounted on the mounting seat, the staff can contact the transformer 150 through the second opening 138 and the third opening 114 to overhaul the transformer 150 in the cabinet body 110.

[0086] In the embodiment of the present application, by forming the second opening 138 in the enclosure 130 and forming the third opening 114 communicated with the second opening 138 in the cabinet body 110, and the opening directions of the second opening 138 and the third opening 114 both face the transformer 150, the staff can overhaul the transformer 150 in the cabinet body 110 without disassembling the cabinet body 110 and the enclosure 130, further simplifying the operation steps of the staff for the transformer 150.
