[0002] With the development of industry, the consumption of electric energy in various industries is becoming larger and larger. Box-type substations are widely used in various power consumption scenarios due to their flexible installation mode and efficient power distribution capability. In a box-type substation, the bus is a key component for electric energy transmission, and the performance of its docking device is crucial to the stable operation of the entire substation.

[0003] At present, the common bus docking device mainly realizes the connection between buses through bolt fixation, welding and other ways. For example, a Chinese patent with application number CN201711348920.2 discloses a dense bus connector device, which uses an insulating partition and a nut to lock and fix, making the plug-in more stable. However, these traditional docking methods have some shortcomings.

The bolt fixation method may loosen due to factors such as vibration, thermal expansion and contraction during long-term operation, leading to poor contact between buses and even loosening, affecting the stability and reliability of electric energy transmission. 2. Although the welding method is relatively firm, once the welding is completed, the disassembly and maintenance of the bus will become very difficult, requiring professional equipment and personnel to operate, increasing maintenance costs and time.

[0027] EMBODIMENT

[0028] The embodiment provides a box-type substation modular bus structure, referring to Figures 1-4 comprising a first bus duct 1 and a second bus duct 2, the first bus duct 1 and the second bus duct 2 are respectively provided with a bus 11, the first bus duct 1 is provided with an insertion mechanism at one end close to the second bus duct 2, the second bus duct 2 is provided with a socket mechanism and a locking mechanism at one end close to the first bus duct 1, the insertion mechanism can be inserted into the socket mechanism and locked by the locking mechanism. After the insertion mechanism is inserted into the socket mechanism, the insertion mechanism is locked on the socket mechanism by the locking mechanism.

[0029] When the operator abuts the first bus duct 1 and the second bus duct 2, the insertion mechanism on the first bus duct 1 is inserted into the socket mechanism on the second bus duct 2, and then the locking mechanism is moved towards the socket mechanism, so as to realize the fixation of the insertion mechanism and the socket mechanism. Not only can the stability of the connection between the first bus duct 1 and the second bus duct 2 be ensured, but also the quick installation and disassembly between the first bus duct 1 and the second bus duct 2 can be realized, the labor intensity of the operator is reduced, and the work efficiency is improved.

[0030] The insertion mechanism comprises a first fixed plate 3, a plurality of insertion rods 6 are arranged on one side of the first fixed plate 3 close to the second bus duct 2, and a turnover plate 8 is arranged at one end of the insertion rod 6 away from the first fixed plate 3 through a hinge. The insertion rod 6 and the turnover plate 8 at the end of the insertion rod 6 can be inserted into the socket mechanism. The socket mechanism comprises a second fixed plate 4, and a plurality of insertion holes 5 matched with the insertion rod 6 are arranged on the second fixed plate 4. The insertion rod 6 and the turnover plate 8 can be inserted into the insertion hole 5. The locking mechanism comprises a pressing nut 10, a thread 9 is arranged on the second bus duct 2, the pressing nut 10 is sleeved on the second bus duct 2 through the thread 9, and the pressing nut 10 works towards the second fixed plate 4. The cooperation of the pressing nut 10 and the thread 9 can rotate the pressing nut 10 to move towards the turnover plate 8 and be fixed.

[0031] When the first bus duct 1 and the second bus duct 2 are butted, the plurality of insertion rods 6 on the first fixed plate 3 and the corresponding folding plates 8 are respectively inserted into the corresponding insertion holes of the second fixed plate 4, and since the folding plates 8 can completely pass through the insertion holes of the second fixed plate 4, the operator can fold the folding plates 8 outward by 90°, so that the side surface of the folding plate 8 abuts against the side of the second fixed plate 4 away from the first fixed plate 3, and then the operator rotates the extrusion nut 10, and since the extrusion nut 10 is installed on the second bus duct 2 through the thread 9, the operator can screw the extrusion nut 10 in the direction of the first fixed plate 3 until the end of the extrusion nut 10 abuts against the side of the folding plate 8 away from the second fixed plate 4, so as to extrude the folding plate 8 between the second fixed plate 4 and the extrusion nut 10, and ensure the stability of the connection between the first bus duct 1 and the second bus duct 2, and avoid loosening between the first bus duct 1 and the second bus duct 2 due to changes in external conditions.

[0032] The surface of the extrusion nut 10 is provided with anti-skid lines, and one end of the extrusion nut 10 close to the second fixed plate 4 is provided with a buffer pad. The friction force is increased to prevent the operator's hands from slipping and to realize the rapid screwing of the extrusion nut 10.

[0033] The anti-skid lines can increase the friction force between the operator's hands and the extrusion nut 10 to realize the rapid screwing of the extrusion nut 10 to extrude or release the folding plate 8, and the buffer pad can avoid damage to the folding plate 8 when the extrusion nut 10 extrudes the folding plate 8, and ensure the service life of the device.

[0034] The folding plate 8 is installed at the end of the insertion rod 6 through the spring hinge 7. When the folding plate 8 is not subjected to external force, it always remains parallel to the insertion rod. The end of the folding plate 8 is provided with a wedge-shaped gap matched with the extrusion nut 10. When the extrusion nut 10 moves towards the folding plate 8 for extrusion, the folding plate 8 is automatically folded.

[0035] As Figure 4The folding plate 8 is installed at the end of the insertion rod 6 through the spring hinge 7 (the spring hinge 7 is a prior structure, and details are not described herein), so that the insertion rod 6 and the folding plate 8 can be kept parallel when not subjected to external force. The end of the folding plate 8 is provided with a wedge-shaped gap matched with the extrusion nut 10. When the extrusion nut 10 is screwed to the folding plate 8, the gap of the folding plate 8 is contacted first with the end of the extrusion nut 10. In the process of continuously screwing the extrusion nut 10 to the folding plate 8, the folding plate 8 is changed from the parallel state with the insertion rod 6 to the state of 90° angle with the insertion rod 6. The extrusion nut 10 extrudes the folding plate 8 on the second fixed plate 4, so as to realize the stable connection of the first bus duct 1 and the second bus duct 2. When it is needed to separate the first bus duct 1 and the second bus duct 2, the extrusion nut 10 is reversely screwed, and the extrusion nut 10 gradually moves away from the second fixed plate 4. At this time, the folding plate 8 gradually recovers to the parallel state with the insertion rod 6 under the action of the spring hinge 7. The insertion rod 6 and the folding plate 8 are quickly pulled out from the insertion hole of the second fixed plate 4, so as to realize the quick separation of the first bus duct 1 and the second bus duct 2, and improve the work efficiency of the operator.

[0036] In the embodiment, the working principle of the box-type substation modular bus structure is as follows:

[0037] Firstly, when the first bus duct 1 and the second bus duct 2 are butt-jointed, the plurality of insertion rods 6 and the folding plates 8 at the ends of the insertion rods 6 are inserted into the corresponding insertion holes of the second fixed plate 4. Then, the operator screws the extrusion nut 10. The extrusion nut 10 is continuously reversely moved to the second fixed plate 4. In the process of continuously screwing the extrusion nut 10, the folding plate 8 is changed from the parallel state with the insertion rod 6 to the state of 90° angle with the insertion rod 6. The extrusion nut 10 extrudes the folding plate 8 on the second fixed plate 4, so as to realize the stable connection of the first bus duct 1 and the second bus duct 2. When it is needed to separate the first bus duct 1 and the second bus duct 2, the extrusion nut 10 is reversely screwed, and the extrusion nut 10 gradually moves away from the second fixed plate 4. At this time, the folding plate 8 gradually recovers to the parallel state with the insertion rod 6 under the action of the spring hinge 7. Finally, the insertion rod 6 and the folding plate 8 are quickly pulled out from the insertion hole of the second fixed plate 4, so as to realize the quick separation of the first bus duct 1 and the second bus duct 2.

[0038] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or additions or substitutions within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
