Description

Technical Field

[0001] The utility model relates to the technical field of power transmission equipment, in particular to a vehicle-mounted substation. Background Art

[0002] With economic development, the load on the power grid continues to rise, and problems such as overload and excessive current in substations frequently occur. Therefore, mobile vehicle-mounted substations, an emergency power supply device, have been widely used. Due to their mobility requirements, vehicle-mounted substations should undergo a route survey before transportation. The structure, size, slope, inclination, turns, and load-bearing capacity of the road and the bridges, culverts, and restricted roads along the way should be investigated. The conditions of overhead routes (power, communications, etc.), overpasses, highway facilities, and other high-altitude obstacles along the way should be investigated, and treatment plans should be prepared as appropriate. During the entire transportation process (including railways, roads, and waterways), impacts, severe vibrations, and bumps should be avoided. The inclination of the transformer body should not exceed 15 degrees in the long axis direction and not exceed 10 degrees in the short axis direction. The transformer must not be displaced.

[0003] To this end, the prior art invention patent application publication number CN114038654A provides a transformer fixing system and a vehicle-mounted mobile substation. The transformer fixing system includes: a vertical shock absorbing device, which is vertically arranged perpendicular to the forward direction of the transport vehicle, and its two ends are respectively connected to the oil tank fixing plate on the side wall of the transformer body and the vehicle beam of the transport vehicle. The vertical shock absorbing device can effectively absorb the energy input in the vertical direction caused by the bumps on the road, thereby preventing the transformer body from being damaged. A horizontal shock absorbing device, which is horizontally arranged parallel to the forward direction of the transport vehicle, and its two ends are respectively connected to the end of the transformer body and the vehicle beam, thereby preventing the transformer body from being damaged. The transformer fixing system provided by the present invention reduces the mechanical damage caused to the vehicle-mounted transformer during transportation and movement.

[0004] In the process of realizing the present invention, the inventors discovered that the prior art has at least the following problems: the patented technology installs a shock-absorbing device on the transformer, which reduces the mechanical damage of the transformer, but cannot improve the transformer's anti-tilt ability. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the utility model develops a vehicle-mounted substation. The transformer in the vehicle-mounted substation can withstand a larger tilt angle, thereby improving the maneuverability of the vehicle-mounted substation and reducing the difficulty of transportation.

[0006] The technical solution to the technical problem solved by the present invention is as follows: an embodiment of the present invention provides a vehicle-mounted substation, comprising a transport vehicle and a transformer fixed in a compartment behind the transport vehicle, the transformer comprising a box, a coil, an iron core, an upper splint, and a lower splint, the iron core being composed of a plurality of iron sheets, the coil being mounted on the iron core, the upper splint and the lower splint respectively clamping the top and bottom of the iron core, the coil, the iron core, and the upper splint being arranged inside the box, the upper splint being connected to the inner wall of the box, the upper splint being respectively arranged on both sides of the top of the iron core, and the lower splint being arranged on the top of the iron core. A top plate is located on top of the clamping plate, connecting the two upper clamping plates. An upper fixing rod is mounted on the top plate, connecting the top plate to the top surface of the box body via the upper fixing rod. Bolts connect the top plate and the box body's top surface at each end of the upper fixing rod. Vertical upper locating pins are located on the inner upper end of the box body's sidewalls, and pin holes corresponding to the upper locating pins are located on the top plate. Lower clamping plates are located on either side of the bottom of the core, and a base is located below the lower clamping plate. A lower locating pin is located on the bottom of the box body, and a pin hole corresponding to the lower locating pin is located on the base. The upper fixing rod, upper locating pin, lower locating pin, and lower fixing rod are made of insulating plastic.

[0007] As an optimization, a lower fixing rod is further provided between the base and the bottom surface of the box body, and both ends of the lower fixing rod are connected to the base and the box body by bolts respectively.

[0008] As an optimization, the lower fixing rods are respectively provided at the four corners and the middle of the long side of the base.

[0015] The effects provided in the content of the utility model are only the effects of the embodiments, rather than all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0016] 1. The transformer's design and internal structure require specific stability.

DETAILED DESCRIPTION

[0026] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0027] Figures 1 to 6 In one embodiment of the present invention, a vehicle-mounted substation includes a transport vehicle and a transformer fixed in a compartment behind the transport vehicle. Figure 1As shown, the transformer includes a box 1, a coil 2, an iron core 3, an upper clamping plate 4, and a lower clamping plate 12. The iron core 3 is composed of multiple pieces of iron sheets. The coil 2 is installed on the iron core 3. The upper clamping plate 4 and the lower clamping plate 12 respectively clamp the top and bottom of the iron core 3. The coil 2, the iron core 3, and the upper clamping plate 4 are arranged inside the box 1. The upper clamping plate 4 is connected to the inner wall of the box 1. Figure 5 As shown, the upper splint 4 is provided on both sides of the top of the iron core 3, and a top plate 43 is further provided on the top of the upper splint 4. The top plate 43 connects the two upper splints 4, and an upper fixing rod 7 is also installed on the top plate 43. The top plate 43 is connected to the top surface of the box body 1 through the upper fixing rod 7, and the two ends of the upper fixing rod 7 are respectively connected to the top plate 43 and the top surface of the box body 1 by bolts; a vertical upper positioning pin 8 is also provided on the inner upper end of the side wall of the box body 1, and a pin hole corresponding to the upper positioning pin 8 is provided on the top plate 43; Figure 6 As shown, a lower clamping plate 12 is provided on both sides of the bottom of the iron core 3, and a base 10 is also provided below the lower clamping plate 12. A lower positioning pin 9 is provided at the bottom of the box body 1, and a pin hole corresponding to the lower positioning pin 9 is provided on the base 10. The upper fixing rod 7, the upper positioning pin 8, the lower positioning pin 9, and the lower fixing rod 13 are made of insulating plastic. When transporting and loading and unloading the transformer, the transformer's tilt angle is required to be no more than 15 degrees in the longitudinal direction and no more than 10 degrees in the width direction. The design and internal structure of the transformer require specific stability. Exceeding this angle may cause unnecessary pressure on the iron core inside the transformer, thereby affecting its performance and safety. By providing the upper positioning pin 8 and the lower positioning pin 9, the iron core 3 can be fixed in the horizontal direction, and the upper fixing rod 7 can fix the iron core 3 in the vertical direction, thereby achieving comprehensive fixation of the iron core 3. The transformer in the vehicle-mounted substation can withstand a larger tilt angle, which improves the mobility of the vehicle-mounted substation and reduces the difficulty of transportation.

[0028] like Figure 1 As shown, a lower fixing rod 13 is further provided between the base 10 and the bottom surface of the box body 1, and the two ends of the lower fixing rod 13 are respectively connected to the base 10 and the box body 1 by bolts. The lower fixing rod 13 is respectively provided at the four corners and the middle of the long side of the base 10. The transformer also includes an input interface 5 and an output interface 6, and the input interface 5 and the output interface 6 are provided on the side of the box body 1. By arranging the input interface 5 and the output interface 6 on the side of the box body 1, the overall height of the transformer can be reduced and the stability of the transformer can be improved. The input interface 5 and the output interface 6 are connected to the coil 2 through a cable, and the cable is fixed to the upper clamping plate 4, the lower clamping plate 12 or the coil 2 through the pressure plate 1 41 and the pressure plate 2 42. The iron core 3 is close to the end of the box body 1 away from the input interface 5. By arranging the iron core 3 close to the end of the box body 1 away from the input interface 5, the center of gravity of the transformer can be at the geometric center position, thereby improving the stability of the transformer.

[0029] like Figure 3As shown, six upper fixing rods 7 are provided, one at each of the four corners and the middle of the long side of the top plate 43. One upper positioning pin 8 is provided at each of the four corners of the top plate 43, and one lower positioning pin 9 is provided at each of the four corners of the base 10.

[0030] like Figure 2 As shown, the outer side of the box body 1 is further provided with a hanging lug 11. The box body 1 is fixed to the carriage of the transport vehicle through the hanging lug 11.

[0031] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the utility model.
