[0030] In the related art, the high-voltage chamber box body of a transformer is mostly manufactured by welding, and after the box body is welded and formed, powder coating treatment is required to enable the box body to have better protection performance. However, certain fine pores are likely to be formed at the joints of the box body welding, resulting in that the powder coating material cannot well and fully fill and cover the joints of the box body, making it easy for water vapor to invade the joint pores of the box body, causing the box body to rust, and further resulting in low durability of the box body, reducing the practicability and structural reliability of the transformer. To solve the above problems, this application proposes a box body 100.
[0031] Please refer to Figures 1 to 7 , in an embodiment of this specification, the box body 100 includes a base 10, a top cover 30, a fence 50, and a protective door. The top cover 30 is arranged at a relative interval with respect to the base 10; the fence 50 is arranged between the base 10 and the top cover 30 and is spliced and installed on the base 10 and the top cover 30. The fence 50, the base 10, and the top cover 30 enclose a receiving cavity 10a. The fence 50 is provided with an entrance / exit 511 communicating with the receiving cavity 10a; the protective door is installed on the fence 50 and is used to open or cover the entrance / exit 511.
[0032] It can be understood that a transformer may include a high-voltage chamber and a low-voltage chamber. By using the box body 100 with certain enclosed protection performance to accommodate the high-voltage devices in the high-voltage chamber, the high-voltage devices may include high-voltage transformation equipment, switchgear, fuses, tap changers, and related auxiliary equipment, etc. It can effectively ensure the stable operation of the high-voltage devices under the protection of the box body 100, avoid the high-voltage devices being affected by the external environment, and at the same time can effectively isolate the power leakage during the operation of the high-voltage devices, ensure the safe operation of the operators, and reduce the safety hazards of the transformer.
[0033] In this application, the box body 100 can be formed by connecting and enclosing a base 10, a fence 50, and a top cover 30 to form an accommodation cavity 10a for accommodating and installing a high-voltage device. By providing an entrance / exit 511 on the fence 50 that communicates with the accommodation cavity 10a, operators can enter and exit the accommodation cavity 10a through the entrance / exit 511 to perform operations such as maintenance and repair on the high-voltage device. The box body 100 can use hinge-like joints on the fence 50 to connect a protective door, and the protective door can be moved on the fence 50 to open and close the entrance / exit 511, so that the box body 100 remains in a closed and protected state during daily operation, ensuring the stable and reliable operation of the transformer. Among them, the fence 50 can be made of a plate with a certain thickness, or flanging structures can be provided on the upper and lower sides of the fence 50 to fit and abut against the base 10 and the top cover 30, ensuring sufficient contact and installation between the fence 50 and the base 10 and the top cover 30. At this time, fasteners such as bolts, self-tapping screws, pins, and clips can be used to connect the fence 50 to the base 10 and to connect the fence 50 and the top cover 30; or a fixed structure that cooperates and engages with each other can be provided between the fence 50 and the base 10, and a fixed structure that cooperates and engages with each other can be provided between the fence 50 and the top cover 30. Then, under the fastening action of the fasteners or under the combined fixing action of the fence 50 and the base 10 and the top cover 30, the stable splicing and installation of the base 10, the top cover 30, and the fence 50 can be well achieved, enabling the box body 100 to be processed and formed by a splicing structural design, ensuring the overall structural stability of the box body 100.
[0034] When the base 10, the top cover 30, and the fence 50 are assembled to form the box body 100 by using a splicing installation method, during the assembly of the box body 100, the components such as the base 10, the top cover 30, the fence 50, and the protective door can be subjected to powder coating treatment first to ensure that the surfaces of all components can be fully sprayed with protective materials, and then the components are spliced and assembled to form the box body 100. In this way, the joints between all components of the box body 100, between the base 10 and the fence 50, and between the top cover 30 and the fence 50 can all maintain good powder coating treatment, so that the box body 100 can achieve better insulation protection performance, waterproof performance, and anti-corrosion performance, etc., which is beneficial to better improving the service life of the box body 100, ensuring that the box body 100 can better protect the high-voltage device in an outdoor environment, realizing the stable and reliable operation of the transformer, and effectively improving the practicability and structural reliability of the box body 100.
[0035] In one embodiment of this specification, the base 10, the top cover 30, and the enclosure 50 are spliced and installed to form the box body 100. This enables the box body 100 to be formed by assembling the spray-coated components. Compared with the processing method of forming the box body 100 by welding and then spray-coating, it can effectively avoid the situation of insufficient spray-coating at the joints of the box body 100, so that the overall surface layer of the box body 100 can be fully attached with the protective material, enabling the box body 100 to achieve better protective performance, effectively extending the service life of the box body 100, ensuring the stable and reliable operation of the transformer, and improving the practicality and structural reliability of the box body 100.
[0036] Refer to Figure 1 and Figure 4 In one embodiment of this specification, the protective door includes an outer door 71 and an inner door 73. The outer door 71 and the inner door 73 are respectively installed on the enclosure 50 in a manner that can be opened and closed. The outer door 71 is provided on the outer periphery of the enclosure 50 and can cover the inner door 73.
[0037] In this embodiment, the protective door can include an inner door 73 and an outer door 71. Hinged components such as hinges can be used to install the inner door 73 and the outer door 71 on the enclosure 50 respectively, so that the box body 100 can use the inner door 73 to close the entrance 511 and then use the outer door 71 to cover the inner door 73. This is conducive to achieving a better protective effect for the box body 100 by using the structure of the double doors, so as to better prevent dust and water vapor from entering the accommodation cavity 10a through the gaps of the outer door 71 under the isolation of the inner door 73, and better isolate the high-voltage device in the box body 100 from the influence of the external environment; and it can keep the inner door 73 closed when the transformer is operating, avoiding the operator from accidentally opening the door, ensuring the stable and reliable operation of the transformer, and further improving the practicality and reliability of the box body 100.
[0038] Among them, the inner door 73 and the outer door 71 can be rotated in opposite directions to open the entrance 511, or the size of the outer door 71 can be set to be larger than the size of the inner door 73, and the size of the inner door 73 can be set to be equal to the size of the entrance 511, so that the opening and closing of the inner door 73 and the outer door 71 on the enclosure 50 do not interfere with each other, enabling the operator to stably open the outer door 71 and the inner door 73 to enter the accommodation cavity 10a for maintaining and repairing the high-voltage device, and further improving the practicality and structural reliability of the box body 100.
[0039] Refer to Figures 1 to 3 In one embodiment of this specification, a water guide groove 513 is recessed on the outer periphery of the enclosure 50. The entrance 511 is provided on the inner wall of the groove of the water guide groove 513, and at least part of the structure of the outer door 71 can be accommodated in the water guide groove 513.
[0040] In this embodiment, by forming a water guide groove 513 in a recess on the outer periphery of the enclosure 50, an access opening 511 can be formed on the inner wall of the groove of the water guide groove 513 to communicate with the accommodation cavity 10a. The size of the water guide groove 513 can be set slightly larger than the size of the outer door 71. Further, when the outer door 71 covers the access opening 511 and the inner door 73, at least part of the structure of the outer door 71 can be accommodated in the water guide groove 513, which is beneficial to making the outer periphery of the enclosure 50 of the box body 100 flatter, reducing the protruding structures on the enclosure 50, and making the overall aesthetics of the box body 100 better. In addition, compared with the method of connecting the outer door 71 to open and close by providing a protruding flange around the access opening 511 on the outer periphery of the enclosure 50, using the water guide groove 513 to accommodate the outer door 71 is beneficial to preventing foreign matters such as sand, dust, etc. from accumulating at the protruding flange of the enclosure 50, which is beneficial to reducing the cleaning burden of the operator on the box body 100 and realizing more convenient maintenance operation of the transformer. By adopting the embedded water guide groove 513 structure, it is possible to better reduce the water flowing on the outer periphery of the enclosure 50 from leaking to the gap between the outer door 71 and the enclosure 50, which is beneficial to better improving the protection performance of the box body 100 and further improving the practicability and reliability of the box body 100.
[0041] Refer to Figure 1 、 Figure 2 and Figure 5 , in an embodiment of the present specification, the enclosure 50 includes a door frame 51, a back plate and two side plates 53. The door frame 51 is provided with the water guide groove 513, and the back plate is disposed opposite to the door frame 51. The two side plates 53 are disposed opposite to each other and are respectively spliced with the back plate and the door frame 51. The door frame 51, the back plate and the two side plates 53 are all spliced and installed on the base 10 and the top cover 30.
[0042] In this embodiment, the enclosure 50 can be formed by splicing and installing the door frame 51, the back plate and the side plates 53, which is conducive to setting the enclosure 50 with a structure assembled by multiple plates, reducing the production difficulty of the enclosure 50 and further reducing the overall construction cost of the box body 100. At this time, a water guide groove 513 can be recessed on the door frame 51 corresponding to the size of the outer door 71 to ensure the fitting and assembly of the outer door 71 and the door frame 51, and further realize the convenient production and processing of the enclosure 50. Among them, the box body 100 can connect the door frame 51, the back plate and the two side plates 53 with fasteners such as bolts, self-tapping screws, pins or clip fasteners; or a mutually matching fixing structure can be respectively arranged between the side plate 53 and the door frame 51 and between the side plate 53 and the back plate. Then, under the fastening action of the fasteners or under the fitting and fixing action of the side plate 53 with the door frame 51 and the back plate, the splicing and installation of the door frame 51, the back plate and the side plates 53 can be realized, so that the box body 100 can better realize the structure setting of the overall splicing and installation, which is conducive to splitting the box body 100 into multiple smaller parts for transportation and realizing more convenient transportation and assembly of the box body 100; at the same time, the box body 100 can better perform spray painting treatment on each component and then splice and install them into shape, which is conducive to better avoiding insufficient spray painting of the box body 100 and being eroded by water vapor with a certain probability, so that the box body 100 can have a longer service life and further improve the structural stability and reliability of the box body 100.
[0043] Referring to Figure 3 , in an embodiment of the present specification, the enclosure 50 is provided with a sealing colloid 515, and the sealing colloid 515 is connected to the outer periphery of the enclosure 50 and is arranged around the entrance 511, and the sealing colloid 515 abuts against the outer door 71.
[0044] In this embodiment, by arranging the sealing colloid 515 around the entrance 511, when the outer door 71 covers the entrance 511 and the inner door 73, it can abut against the sealing colloid 515. The sealing colloid 515 can be a colloid structure such as silica gel or rubber with a certain elasticity, and the sealing colloid 515 can have high wear resistance, high temperature resistance and waterproof performance, etc. Under the action of the sealing colloid 515, when the outer door 71 closes the entrance 511, it presses against the sealing colloid 515, causing the sealing colloid 515 to undergo a certain elastic deformation. Then, under the acting force of the sealing colloid 515 to recover the elastic deformation, the gap between the outer door 71 and the enclosure 50 can be stably sealed, effectively preventing fine particles and water vapor, etc. from entering the accommodation cavity 10a through the gap between the outer door 71 and the enclosure 50, realizing the reliable protection of the high-voltage device by the box body 100, and further improving the practicability and reliability of the box body 100.
[0045] In addition, in some embodiments, when the retaining wall 50 is provided with a water guide groove 513 for accommodating the outer door 71, the sealing colloid 515 can be arranged on the inner wall of the groove of the water guide groove 513 and surround the entrance 511. At this time, under the action of the water guide groove 513, it is possible to better reduce the impact of foreign matters such as sand and wind on the sealing colloid 515, which is beneficial to better extending the service life of the sealing colloid 515 and further improving the structural stability and reliability of the box body 100.
[0046] Refer to Figure 1 and Figure 2 , in an embodiment of the present specification, the retaining wall 50 is provided with a water retaining edge 55, and the water retaining edge 55 is connected to the outer periphery of the retaining wall 50 and is arranged above the entrance 511.
[0047] In this embodiment, by arranging the water retaining edge 55 above the entrance 511, the water retaining edge 55 can be a baffle structure with a length greater than the width of the protection door. The water retaining edge 55 can be used to block part of the water falling above the protection door, and at the same time reduce the water flow on the outer periphery of the retaining wall 50 from entering the accommodation cavity 10a through the gap between the protection door and the retaining wall 50, realizing a better waterproof effect of the box body 100, so that the box body 100 can better protect the high-voltage device in the outdoor environment, ensure the stable operation of the transformer, and further improve the practicability and reliability of the box body 100.
[0048] Refer to Figure 5 and Figure 7 , in an embodiment of the present specification, the box body 100 further includes a mounting beam 90, and the mounting beam 90 is arranged in the accommodation cavity 10a and is spliced and installed on the retaining wall 50.
[0049] It can be understood that the high-voltage device further includes a sensor 200, and the sensor 200 can be used to detect whether the three-phase transformer equipment of the high-voltage device is energized, and further can judge whether the high-voltage chamber of the transformer is in an operating state, so that the transformer can trigger the display instrument or alarm device to respond to the corresponding signal according to the detection result of the sensor 200; when the box body 100 is provided with the inner door 73 and the outer door 71 structure, the locking mechanism of the inner door 73 can also be controlled to act when the sensor 200 detects that the three-phase transformer equipment of the high-voltage device is energized, so that the inner door 73 of the box body 100 is tightly closed, avoiding the operator from accidentally opening the door, which is beneficial to better reducing the safety hazard of the transformer. At this time, the box body 100 can set a mounting beam 90 at the top of the accommodation cavity 10a for the sensor 200 to be installed and fixed, and the sensor 200 can be connected to the mounting beam 90 by using an insulator string, and the insulator string is used to better isolate the electrical connection between the sensor 200 and the mounting beam 90, effectively avoiding the box body 100 from being energized and ensuring the stable operation of the transformer.
[0050] Inside the accommodation cavity 10a, raised structures such as angle steels or receiving platforms can be respectively arranged on two opposite inner sidewalls of the accommodation cavity 10a, so that the installation beam 90 can be supported on the raised structure, and fasteners such as bolts, self-tapping screws, and pins are used to connect and fix the raised structure and the installation beam 90, so that the installation beam 90 can be spliced and installed in cooperation with the enclosure 50, realizing a better overall splicing structure design for the box body 100 structure. Compared with the box body 100 structure formed by welding and processing, by splicing and installing the installation beam 90 and the enclosure 50, the installation beam 90 can be connected and installed with the sensor 200 and then moved into the accommodation cavity 10a for assembly. There is no need for construction workers to assemble the sensor 200 in the relatively small accommodation cavity 10a, which is beneficial to making the transformer more convenient for processing and installation, and further improving the practicability and reliability of the box body 100.
[0051] Refer to Figure 5 and Figure 7 , in an embodiment of the present specification, the enclosure 50 is provided with two support structures 57, the two support structures 57 are respectively connected to two opposite inner sidewalls of the accommodation cavity 10a, and two ends of the installation beam 90 are respectively installed on the support structures 57.
[0052] In this embodiment, by respectively connecting and installing the support structures 57 on two opposite inner sidewalls of the accommodation cavity 10a, the support structure 57 can be a structure such as a channel steel or a column with a certain width, and fasteners such as bolts, self-tapping screws, and pins can be used to stably connect the support structure 57 to the enclosure 50, so that the support structure 57 can play a better stable support role. Furthermore, by respectively installing and fixing two ends of the installation beam 90 on the support structure 57, the support structure 57 can be used to support and hold the installation beam 90, which is beneficial to reducing the shaking of the installation beam 90 during the transportation of the box body 100 and the use of the transformer, so that the sensor 200 can be stably arranged in the accommodation cavity 10a, ensuring the detection accuracy and reliability of the sensor 200, and further improving the structural stability and reliability of the box body 100.
[0053] Refer to Figure 5 and Figure 6 , in an embodiment of the present specification, the support structure 57 includes a vertical rod 571 and a cross rod 573, the cross rod 573 is connected to one end of the vertical rod 571, and the end of the installation beam 90 is installed and connected to the cross rod 573.
[0054] In this embodiment, the support structure 57 can be connected to the inner wall of the enclosure 50 by using the vertical rod 571, and the cross rod 573 is connected to the end of the vertical rod 571 and the inner wall of the enclosure 50, so that the support structure 57 can play a more stable supporting role. At this time, under the action of the cross rod 573, the contact area between the cross rod 573 and the mounting beam 90 can be effectively increased, so that the support structure 57 can support and hold the mounting beam 90 more stably and reliably, which is beneficial to better prevent the mounting beam 90 from shaking during the transportation of the box body 100 and the operation of the transformer, ensure the stable support of the mounting beam 90 for the sensor 200, and achieve a more accurate and reliable detection effect of the sensor 200, further improving the practicability and structural reliability of the box body 100.
[0055] Referring to Figure 5 and Figure 6 , in one embodiment of the present specification, the top cover 30 is provided with a support partition 31, and the support partition 31 is disposed in the accommodation cavity 10a and connected to the mounting beam 90.
[0056] In this embodiment, the box body 100 can be provided with a support partition 31 on the top cover 30. The support partition 31 can be a plate structure such as an L-shaped plate or a C-shaped plate. When the support partition 31 is connected and installed on the side of the top cover 30 facing the base 10, it can have a certain convex structure, which is beneficial to connecting and fixing the mounting beam 90 by using the convex structure of the support partition 31. At this time, fasteners such as bolts, self-tapping screws, pins or clips can be used to connect and install the mounting beam 90 and the support partition 31, realizing the convenient and stable assembly connection between the mounting beam 90 and the support partition 31, so that the box body 100 can achieve a better splicing and assembly structure, further improving the practicability and reliability of the box body 100. Under the connection and fixing action of the support partition 31 and the enclosure 50 on the mounting beam 90, the mounting beam 90 can be more stably and reliably installed in the accommodation cavity 10a, which is beneficial to better prevent the mounting beam 90 from shaking during the transportation of the box body 100 and the operation of the transformer, ensure the stable detection of the sensor 200 in the transformer, and realize the more stable and reliable operation of the transformer, further improving the practicability and structural reliability of the box body 100.
[0057] The present application also proposes a transformer, which includes a high-voltage device and a box body 100. The specific structure of the box body 100 refers to the above embodiment.
