[0002] As a crucial auxiliary device for rectifier transformers in power systems, the oil-air cooler is responsible for regulating the operating temperature of the rectifier transformer and ensuring that the equipment operates within its normal temperature range. Its stable operation is essential for voltage regulation and power quality across the entire rectifier system. As a key component controlling the operation of the oil-air cooler, the layout and wiring of the electrical components within the oil-air cooling control cabinet are directly related to the cooler's safe operation.

[0003] Copper busbars carry current and connect electrical devices in circuits. In oil-air-cooled control cabinets, these are typically exposed beneath the contactors. While this design facilitates current transmission and heat dissipation, it also poses certain safety risks. During routine inspections or maintenance, inspectors may accidentally leave iron tools or other foreign objects inside the control cabinet. Once these objects land on the exposed copper busbars, they can easily create a short circuit, causing the oil-air-cooled control cabinet's power supply to trip. This short circuit not only causes the oil-air cooler to stop functioning and the rectifier transformer to overheat, but can also lead to more serious electrical failures and even threaten the stable operation of the entire power system.

[0032] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] In the oil air cooling control cabinet, when the maintenance personnel opens the control cabinet door for maintenance, if the iron foreign matter falls on the copper bar below the contactor, the oil air cooling dual power short circuit trip will be caused, which will seriously affect the safe operation of the rectifier system. In order to solve the above technical problem, the present application provides a copper bar protection structure of an oil air cooling control cabinet, which forms a strict protection for the copper bar by setting a protective shell, a protective layer plate and a protective panel on the copper bar.

[0034] Please refer to Figure 1 , Figure 1As a structural schematic view of a copper bar protection structure 2 in an embodiment of the present application, the copper bar protection structure 2 comprises a protection shell 30, a protection panel 40 and a protection layer plate 50, wherein the protection shell 30 is connected with the cabinet 10 and is arranged outside the copper bar 20, the protection panel 40 is connected with the protection shell 30 and can be opened or covered relative to the protection shell 30, and the protection layer plate 50 is connected with the protection shell 30 and is arranged between adjacent copper bars 20.

[0035] The present application will be described in detail below with reference to specific embodiments. It should be noted that the copper bar protection structure 2 in the embodiments of the present application is not limited to be used in the oil air-cooled control cabinet 1 shown in the drawings, but can also be arranged in other oil air-cooled control cabinets 1 or other structures having copper bars 20 to protect the copper bars 20.

[0036] Please refer to Figures 1-3 , Figure 2 As a front view of a copper bar protection structure 2 in an embodiment of the present application, Figure 3 As a sectional view of a copper bar protection structure 2 in an embodiment of the present application, the protection shell 30 comprises a first side plate 31, a top plate 32 and a folded edge 33, two first side plates 31 are arranged opposite to each other along the length direction of the copper bar 20 and are arranged on both sides of the copper bar 20, the top plate 32 is arranged between the two first side plates 31, and the edge of the first side plate 31 away from the top plate 32 is bent outward to form the folded edge 33, and the folded edge 33 is connected to the cabinet 10. Thus, after the folded edge 33 is fixedly connected to the bottom of the cabinet 10, a stable connection is formed between the protection shell 30 and the cabinet 10, and the first side plate 31 and the top plate 32 are arranged outside the copper bar 20, so as to protect the copper bar 20.

[0037] In an embodiment of the present application, the folded edge 33 can be connected to the bottom of the cabinet 10 by screws or bolts, so as to quickly connect the folded edge 33 with the cabinet 10 during installation, improve the installation and disassembly efficiency, and it can be understood that other connection structures can also be used between the folded edge 33 and the cabinet 10.

[0038] Please refer to Figure 4 , Figure 4As an enlarged schematic view of the connecting position of the protective panel 40 and the protective shell 30 in the embodiment of the present application, the protective shell 30 further comprises a first sliding part 34 and a limiting part 35, both of which are arranged on the side of the first side plate 31 close to the top plate 32. The first sliding part 34 and the limiting part 35 are arranged at intervals, and a gap space 36 is formed between them. The protective panel 40 comprises a panel body 41 and a second sliding part 42 arranged on both sides of the panel body 41, and the second sliding part 42 is slidingly connected in the first sliding part 34. The second sliding part 42 can slide towards the limiting part 35 to adjust the position of the protective panel 40 relative to the protective shell 30.

[0039] Further, during use, after the second sliding part 42 slides towards the limiting part 35 and abuts against the limiting part 35, the second sliding part 42 is at least partially arranged in the gap space 36. At this time, the second sliding part 42 can rotate relative to the limiting part 35 in the gap space 36 to adjust the angle of the protective panel 40 relative to the protective shell 30.

[0040] Specifically, the first sliding part 34 is formed with a sliding groove arranged along the thickness direction of the copper bar 20, and the second sliding part 42 is in the form of a cylinder. The cylinder is slidingly connected in the sliding groove and can slide along the thickness direction of the copper bar.

[0041] Therefore, the sliding and rotating combined connecting structure between the protective shell 30 and the protective panel 40 can conveniently open and cover the protective panel 40. The arrangement of the limiting part 35 enables the protective panel 40 to stably stay at the designated position after sliding into place and is not prone to shaking or falling off. During use, the maintenance personnel can adjust the angle and position of the protective panel 40 according to actual needs to meet the use requirements in different scenarios. After the protective panel 40 is covered on the protective shell 30, the protective panel 40 will remain in the covered state due to the effect of gravity and is not prone to being mistakenly opened due to vibration or impact.

[0042] In the embodiment of the present application, in order to facilitate the maintenance personnel to open or cover the protective panel 40, the protective panel 40 further comprises a holding part 43 connected with the panel body 41 for a person to hold to drive the protective panel 40 to open or cover.

[0043] Please refer to Figures 1-6 , Figure 5 As a structural schematic view of the rotating state of the protective panel 40 and the protective shell 30 in the embodiment of the present application, Figure 6 As a structural schematic view of the covered state of the protective panel 40 and the protective shell 30 in the embodiment of the present application, as Figure 1As shown, the protective panel 40 is open relative to the protective shell 30. At this time, the second sliding portion 42 is located at the end of the first sliding portion 34 away from the limiting portion 35, and the protective panel 40 remains housed below the top plate 32, so that maintenance personnel can inspect and maintain the copper busbar. During specific use, maintenance personnel can hold the gripping portion 43 to pull the second sliding portion 42 to slide in the direction close to the limiting portion 35 until the second sliding portion 42 abuts against the limiting portion 35. Then, the maintenance personnel can hold the gripping portion 43 and drive the second sliding portion 42 and the protective panel 40 to rotate until the protective panel 40 covers the protective shell 30. Thus, the protective panel 40 covers the protective shell 30 and forms effective protection for the copper busbar 20, which can prevent foreign objects from falling from above and contacting the copper busbar 20 to cause a short circuit.

[0044] In one embodiment of the present application, the protective layer 50 is connected to the first side panels 31. The protective layer 50 includes a connecting seat 51 and a spacer 52. The connecting seat 51 is disposed between the two first side panels 31, and the spacer 52 is sleeved on the connecting seat 51. The protective layer 50 is used to be spaced between adjacent copper bars 20 to prevent contact and short circuits between adjacent copper bars 20.

[0045] See also Figures 3-7 , Figure 7 This is a schematic diagram of the structure of the protective layer plate 50 according to an embodiment of the present application. Specifically, a mounting groove 310 is provided on the first side plate 31, and first mounting portions 511 are formed at both ends of the connecting base 51. Each first mounting portion 511 is mounted in a mounting groove 310, so that the connecting base 51 and the protective layer plate 50 are disposed between the two first side plates 31. In practice, the matching mounting groove 310 and the first mounting portion 511 ensure the stability of the connecting base 51 and facilitate installation.

[0046] The middle area of ​​the connecting base 51 forms a second mounting portion 512, with both ends of the second mounting portion 512 connected to the first mounting portion 511. The spacer 52 includes a plate-like portion 521 and a connecting portion 522 connected to the plate-like portion 521. The second mounting portion 512 is in the shape of a square column, while the connecting portion 522 has a through-hole. The connecting portion 522 is sleeved onto the second mounting portion 512, allowing the spacer 52 to be detachably connected to the connecting base 51. This detachable connection is not only simple and quick, but also ensures a tight fit between the spacer 52 and the connecting base 51, preventing it from loosening or falling off.

[0047] It should be noted that in the oil air-cooled control cabinet, the plurality of copper bars 20 are arranged in the vertical direction in sequence and are spaced apart, and are installed on the bottom of the cabinet body 10 through the downwardly extending mounting column. In order to avoid the contact between the mounting column and the plurality of copper bars 20 causing the short circuit between the copper bars 20, in the vertical direction, the length of the copper bars 20 arranged from top to bottom decreases in sequence, resulting in that the installation space of each spacing plate 52 is not the same, and therefore, the spacing plate 52 needs to be set according to the width of the copper bar 20.

[0048] In the embodiment of the present application, the detachable connection structure is adopted between the spacing plate 52 and the connecting seat 51, which shows high flexibility and practicability in processing the protection between the plurality of copper bars 20. The staff can conveniently install different specifications of the spacing plate 52 according to the installation space between the copper bars 20, so that the protective layer plate 50 is more in line with the actual demand.

[0049] In the specific size design, in the length direction of the copper bar 20, the length of the spacing plate 52 is Li, the length of the copper bar 20 above the spacing plate 52 is Ai, and the length of the copper bar 20 below the spacing plate 52 is Ai+1. In order to enable the spacing plate 52 to be spaced apart between the adjacent copper bars 20 and form effective protection, Li, Ai and Ai+1 satisfy: Ai+1≤Li<Ai. Further, the spacing between the mounting columns of the copper bar 20 above the spacing plate 52 is Xi, and the length Li of the spacing plate 52 further satisfies: Li<Xi, so that the spacing plate 52 does not interfere with the mounting column, further ensuring the accuracy and reliability of the installation.

[0050] In the embodiment of the present application, the mounting groove 310 includes a plurality of mounting grooves arranged in the vertical direction, and when the protective layer plate 50 is installed, the appropriate mounting groove 310 can be selected to install the connecting seat 51 and the protective layer plate 50 according to the height position of the installation space between the adjacent copper bars 20, and the position of the protective layer plate 50 is flexibly adjusted.

[0051] It should be noted that in the embodiment of the present application, the materials of the protective shell 30, the protective panel 40 and the protective layer plate 50 are all insulating engineering materials. For example, the protective shell 30, the protective panel 40 and the protective layer plate 50 can be made of PC material or composite insulating material. The insulating engineering material has excellent insulating performance and can effectively isolate the current to prevent safety hazards such as leakage or short circuit of electrical equipment. In the high-voltage and high-current environment of the oil air-cooled control cabinet 1, the protective structure made of insulating engineering material is particularly important. It not only can protect the key components such as copper bars in the cabinet from the influence of the external environment, but also can ensure the safety of the staff during maintenance and repair.
