Description

Technical Field

[0001] This invention belongs to the field of transformer technology, and more specifically, relates to a vehicle-mounted de-icing transformer. Background Technology

[0002] DC de-icing primarily works by applying a DC voltage to the transmission line and creating a short circuit at the end of the line. This generates heat, melting the ice and preventing the line from collapsing or breaking due to icing. Currently, a de-icing transformer provides a 12-pulse rectified signal to the DC de-icing device. Conventional de-icing transformers have multiple high-voltage and low-voltage bushings distributed at both ends of the short shaft of the tank. When installed on a transport vehicle, this structure creates a safety hazard when the vehicle turns because the transformer's center of gravity is off-center. Furthermore, this installation method for the high-voltage and low-voltage bushings is inconvenient for users to connect wires. Summary of the Invention

[0003] The purpose of this invention is to provide an ice-melting transformer to solve the technical problems in the prior art where the center of gravity of the ice-melting transformer is eccentric, which leads to safety hazards for transport vehicles, and the installation method of the high-voltage bushing and low-voltage bushing is not conducive to user wiring.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a vehicle-mounted de-icing transformer, comprising:

[0005] The fuel tank has an internal installation space; the installation space is a long strip structure and has a symmetrical axis along the length of the installation space.

[0006] Multiple device bodies are installed inside the oil tank; the multiple device bodies are arranged side by side and along the length of the installation space; the center line of each device body intersects the axis of symmetry perpendicularly.

[0007] Multiple low-pressure bushings are installed at the upper end of the oil tank; the multiple low-pressure bushings are located on one side of the device body and are symmetrically arranged on both sides of the axis of symmetry.

[0008] Multiple high-pressure bushings are installed at the upper end of the oil tank, and multiple high-pressure bushings are located on the other side of the device body; the number of high-pressure bushings is less than the number of low-pressure bushings.

[0009] A tap changer is installed at the upper end of the oil tank; the tap changer and multiple high-voltage bushings are located on the same side of the transformer body and are used to adjust the center of gravity of the vehicle-mounted de-icing transformer.

[0010] In one possible implementation, a plurality of the high-voltage bushings are symmetrically arranged on both sides of the axis of symmetry, and there are at least two tap switches, which are also symmetrically arranged on both sides of the axis of symmetry.

[0011] In one possible implementation, the left and right ends of the oil tank are respectively provided with a first expansion cavity and a second expansion cavity extending outward, and both the first expansion cavity and the second expansion cavity are connected to the installation space; a plurality of low-pressure bushings are installed above the first expansion cavity, and a plurality of high-pressure bushings and the tap changer are installed above the second expansion cavity.

[0012] In one possible implementation, a plurality of the device bodies arranged side by side are sequentially disposed within the first expansion cavity, the mounting space, and the second expansion cavity.

[0013] In one possible implementation, the widths of both the first expansion cavity and the second expansion cavity are greater than the width of the mounting space.

[0014] In one possible implementation, the width of the first expansion cavity is smaller than the width of the second expansion cavity, and the plurality of high-voltage bushings and the tap changer are arranged side by side above the second expansion cavity.

[0015] In one possible implementation, a process ramp is provided between the first expansion cavity, the second expansion cavity, and the oil tank.

[0016] In one possible implementation, the tap changer has a drum-shaped structure and is vertically positioned.

[0017] The beneficial effects of the vehicle-mounted de-icing transformer provided by this invention are as follows: Compared with the prior art, when assembling the vehicle-mounted de-icing transformer, multiple transformer bodies are symmetrically installed in the installation space inside the oil tank, and the distance between the front and rear sides of the transformer body and the front and rear inner walls of the oil tank is equal. Multiple low-voltage bushings and multiple high-voltage bushings are respectively installed on the left and right sides of the upper end of the oil tank, and the multiple low-voltage bushings are symmetrically arranged on both sides of the axis of symmetry, so that the center of gravity of the multiple low-voltage bushings is located on the axis of symmetry. At the same time, the tap changer and the high-voltage bushings are installed on the same side of the oil tank, so that the center of gravity of the multiple low-voltage bushings, multiple high-voltage bushings and the tap changer coincides with the center of gravity of the multiple transformer bodies, so as to ensure that the center of gravity of the entire vehicle-mounted de-icing transformer will not be eccentric, eliminating the safety hazards of the transport vehicle; at the same time, the low-voltage bushings and high-voltage bushings are respectively installed on the left and right sides of the oil tank, which facilitates the user's wiring.

[0026] Please see Figure 1The present invention will now describe the vehicle-mounted de-icing transformer provided. A vehicle-mounted de-icing transformer includes an oil tank 100, a transformer body 200, low-voltage bushings 300, high-voltage bushings 400, and a tap changer 500. The oil tank 100 has an installation space inside; the installation space is a long strip structure and has a symmetrical axis arranged along the length of the installation space; there are multiple transformer bodies 200, all installed inside the oil tank 100; the multiple transformer bodies 200 are arranged side-by-side along the length of the installation space; the centerline of each transformer body 200 intersects the symmetrical axis perpendicularly; there are multiple low-voltage bushings 300, all installed inside the oil tank 100. The upper end of the oil tank 100 is installed; multiple low-voltage bushings 300 are located on one side of the transformer body 200 and are symmetrically arranged on both sides of the axis of symmetry; multiple high-voltage bushings 400 are installed on the upper end of the oil tank 100, and multiple high-voltage bushings 400 are located on the other side of the transformer body 200; the number of high-voltage bushings 400 is less than the number of low-voltage bushings 300; the tap changer 500 is installed on the upper end of the oil tank 100; the tap changer 500 and multiple high-voltage bushings 400 are located on the same side of the transformer body 200 and are used to adjust the center of gravity of the vehicle-mounted de-icing transformer.

[0027] Compared with the prior art, the vehicle-mounted de-icing transformer provided by this invention, during assembly, has multiple transformer bodies 200 installed symmetrically within the installation space of the oil tank 100, with the distance between the front and rear sides of the transformer body 200 and the front and rear inner walls of the oil tank 100 being equal. Multiple low-voltage bushings 300 and multiple high-voltage bushings 400 are respectively installed on the left and right sides of the upper end of the oil tank 100, with the multiple low-voltage bushings 300 symmetrically arranged on both sides of the axis of symmetry, so that the center of gravity of the multiple low-voltage bushings 300 is located on the axis of symmetry. At the same time, the tap changer 500 and the high-voltage bushings 400 are installed on the same side of the oil tank 100, so that the center of gravity of the multiple low-voltage bushings 300, the multiple high-voltage bushings 400 and the tap changer 500 coincides with the center of gravity of the multiple transformer bodies 200, thereby ensuring that the center of gravity of the entire vehicle-mounted de-icing transformer will not be eccentric, eliminating the safety hazards of the transport vehicle; at the same time, the low-voltage bushings 300 and the high-voltage bushings 400 are respectively installed on the left and right sides of the oil tank 100, which facilitates wiring by the user.

[0028] Please see Figure 1 In one specific embodiment of the vehicle-mounted de-icing transformer provided by the present invention, multiple high-voltage bushings 400 are symmetrically arranged on both sides of the axis of symmetry, and at least two tap changers 500 are symmetrically arranged on both sides of the axis of symmetry. The multiple high-voltage bushings 400 are arranged with the axis of symmetry as the center to ensure that the center of gravity of the entire vehicle-mounted de-icing transformer is not affected. The two tap changers 500 not only achieve the purpose of adjusting the center of gravity of the vehicle-mounted de-icing transformer, but also realize multiple different functions.

[0029] Please see Figure 1As a specific embodiment of the vehicle-mounted de-icing transformer provided by the present invention, the left and right ends of the oil tank 100 are respectively provided with an outwardly extending first expansion cavity 110 and a second expansion cavity 120, both of which are connected to the installation space; multiple low-voltage bushings 300 are installed above the first expansion cavity 110, and multiple high-voltage bushings 400 and tap changers 500 are installed above the second expansion cavity 120; the provision of first expansion cavities 110 and second expansion cavities 120 at both ends of the oil tank 100 makes it easier to install multiple low-voltage bushings 300, multiple high-voltage bushings 400 and tap changers 500 on the upper left and right sides of the oil tank 100; it also allows the multiple low-voltage bushings 300, multiple high-voltage bushings 400 and tap changers 500 to be staggered with the multiple transformer bodies 200, resulting in higher stability and reliability.

[0030] Preferably, multiple bodies 200 arranged side by side are sequentially arranged in the first expansion cavity 110, the installation space and the second expansion cavity 120. The two bodies 200 located on the outer side occupy a portion of the first expansion cavity 110 and the second expansion cavity 120 respectively, making full use of the installation space, the first expansion cavity 110 and the second expansion cavity 120, shortening the length of the entire vehicle-mounted de-icing transformer and reducing the weight of the vehicle-mounted de-icing transformer.

[0031] Please see Figure 1 As a specific embodiment of the vehicle-mounted de-icing transformer provided by the present invention, the width of the first expansion cavity 110 and the second expansion cavity 120 are both greater than the width of the installation space, so that multiple low-voltage bushings 300 arranged vertically can be safely and reliably arranged above the first expansion cavity 110. The multiple low-voltage bushings 300 are evenly arranged and have an installation spacing.

[0032] Please see Figure 1 In one specific embodiment of the vehicle-mounted de-icing transformer provided by the present invention, the width of the first expansion cavity 110 is smaller than the width of the second expansion cavity 120, and multiple high-voltage bushings 400 and tap changers 500 are arranged side-by-side above the second expansion cavity 120. In this way, while satisfying the installation requirements of multiple low-voltage bushings 300, multiple high-voltage bushings 400, and tap changers 500, the overall length of the vehicle-mounted de-icing transformer is reduced, resulting in a more compact structure. Setting the width of the second expansion cavity 120 to be greater than the width of the first expansion cavity 110 ensures that the multiple high-voltage bushings 400 and tap changers 500 are arranged side-by-side on the second expansion cavity 120, preventing mutual interference or influence between the high-voltage bushings 400 and the tap changers 500.

[0033] Please see Figure 1In one specific embodiment of the vehicle-mounted de-icing transformer provided by the present invention, a process slope 130 is provided between the first expansion cavity 110, the second expansion cavity 120 and the oil tank 100. By providing the process slope 130, the outer wall dimensions of the first expansion cavity 110, the second expansion cavity 120 and the oil tank 100 are shortened, thereby reducing the weight of the entire vehicle-mounted de-icing transformer. Providing the process slope 130 also improves the appearance characteristics of the vehicle-mounted de-icing transformer.

[0034] Preferably, the tap changer 500 has a drum-shaped structure and is vertically arranged. Multiple vertically arranged tap changers 500 are arranged side by side with multiple high-voltage bushings 400.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
