Description

Technical Field

[0001] This utility model relates to the technical field of busbar connection, specifically a high-load self-disconnecting busbar connection structure with intelligent temperature monitoring. Background Technology

[0002] In substations, the connections between various voltage distribution devices, as well as the connections between transformers and other electrical equipment and their corresponding distribution devices, mostly use bare conductors or stranded wires with rectangular or circular cross-sections, collectively referred to as busbars. The function of busbars is to collect, distribute, and transmit electrical energy. Because a huge amount of electrical energy passes through busbars during operation, they experience significant heating and electrodynamic effects during short circuits. At this time, the short-circuit current can reach tens of times the normal current. The conductor generates instantaneous high temperatures, leading to carbonization of the busbar insulation material and a decrease in the mechanical strength of the metal materials, potentially causing permanent damage. Based on the combined electromagnetic and thermodynamic mechanisms, it is essential to quickly disconnect the faulty busbar connection within a short time using a relay protection system.

[0003] When two adjacent busbars are connected, multiple copper busbars at their ends are interleaved and tightened by double-ended bolts. Under the constant pressure for a long time, the copper busbars may undergo plastic deformation. When a short circuit occurs, the temperature sensor detects a high temperature and drives the double-ended bolts to release the pressure on the copper busbars. However, the plastic deformation of the copper busbars may prevent the two copper busbars from separating smoothly after the double-ended bolts are unlocked, thus affecting the circuit's disconnection function. Utility Model Content

[0004] The purpose of this invention is to provide a high-load self-disconnecting busbar connection structure with intelligent temperature monitoring to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-load self-cutting busbar connection structure for intelligent temperature monitoring includes a connecting section with a box-shaped structure. Multiple first copper busbars and second copper busbars are respectively provided at both ends of the connecting section. The first copper busbars and second copper busbars are staggered, and the busbar can be inserted into both ends of the connecting section and connected to the first copper busbar or the second copper busbar.

[0007] A connecting busbar is rotatably installed inside the second copper busbar, and the end of the connecting busbar away from the second copper busbar can abut against the first copper busbar;

[0008] It also includes electromagnetic control components symmetrically arranged within the connecting section. The electromagnetic control components are driven by a temperature sensor installed within the connecting section and can sequentially control the connecting bar to release from pressing against the first copper busbar and to separate from the first copper busbar via an intermittent transmission component.

[0009] The high-load self-cutting busbar connection structure for intelligent temperature monitoring described above: the end of the second copper busbar away from the busbar has a movable groove for the connection busbar to rotate, and a deflection shaft that can pass through the movable groove is rotatably mounted on the second copper busbar, and the deflection shaft is fixed to multiple connection buses.

[0010] The high-load self-cutoff busbar connection structure for intelligent temperature monitoring as described above: the electromagnetic control component includes a solenoid valve installed in the connection section, and the solenoid valve establishes communication with the temperature sensor;

[0011] It also includes a guide rod installed in the connecting section, the guide rod being arranged along the axial direction of the solenoid valve and slidably provided with a slide valve capable of magnetically attracting the solenoid valve.

[0012] The high-load self-cut-off busbar connection structure for intelligent temperature monitoring as described above: the intermittent transmission component includes a connecting clamp installed on the slide valve, and the two ends of the connecting clamp are respectively formed with a first collar and a second collar;

[0013] It also includes a first drive shaft and a second drive shaft rotatably mounted on the connecting joint, the first collar and the second collar being slidably sleeved on the first drive shaft and the second drive shaft respectively, the first drive shaft being connected to the deflection shaft through a rotating component, and the second drive shaft being used to press the connecting row through a pushing component.

[0014] The high-load self-cutting busbar connection structure for intelligent temperature monitoring described above: a first ball and a second ball are rotatably installed in the first collar and the second collar respectively; a first limiting groove adapted to the first ball is opened on the first drive shaft; and a second limiting groove adapted to the second ball is opened on the second drive shaft.

[0016] The high-load self-cutting busbar connection structure for intelligent temperature monitoring as described above: the pushing component includes a lead screw rotatably installed in the connecting section, the lead screw being connected to the second transmission shaft via a second bevel gear set, a threaded sleeve being threadedly connected to the lead screw, the threaded sleeve being slidably connected to a limiting rod installed in the connecting section and parallel to the axis of the lead screw, and a pressure plate capable of squeezing the connecting bar being provided at the end of the threaded sleeve away from the lead screw.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] When a short circuit occurs in the circuit, high temperatures are instantly generated within the connecting joint. When the temperature sensor detects that the temperature exceeds the threshold, it sends a signal to the electromagnetic control component. Upon receiving the signal, the electromagnetic control component's circuit is energized, generating magnetism. This controls the intermittent transmission component to generate intermittent force, relieving the pressure on the multiple first copper busbars and connecting busbars. This allows the connecting busbars to deflect relative to the second copper busbars, enabling rapid separation of the connecting busbars from the first copper busbars within a short time. This separation is unaffected by the plastic deformation caused by the long-term pressure on the first copper busbars. Without external intervention, the circuit can be quickly and automatically cut off or the busbar connection status can be adjusted, thereby extending the service life of the electrical equipment and improving the reliability of the busbar conductivity.

Detailed Implementation

[0027] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0028] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0029] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0030] Please see Figures 1-7 In this embodiment of the present invention, a high-load self-cutting busbar connection structure for intelligent temperature monitoring includes a connecting section 1 in the form of a box. Multiple first copper busbars 3 and second copper busbars 4 are respectively provided at both ends of the connecting section 1. The first copper busbars 3 and the second copper busbars 4 are staggered, and the busbar can be inserted into both ends of the connecting section 1 and connected to the first copper busbars 3 or the second copper busbars 4 respectively.

[0031] A connecting bar 5 is rotatably installed inside the second copper busbar 4, and the end of the connecting bar 5 away from the second copper busbar 4 can abut against the first copper busbar 3;

[0032] It also includes electromagnetic control components symmetrically arranged in the connecting section 1. The electromagnetic control components are driven by temperature sensor 2 installed in the connecting section 1. Through intermittent transmission components, they can sequentially control the connecting bar 5 to release the pressure on the first copper bar 3 and to separate from the first copper bar 3.

[0033] In this embodiment, a connecting joint 1 is set between two busbars. One end of each busbar is locked with a first copper busbar 3 and a second copper busbar 4 in the connecting joint 1 using double-ended threads. Once a short circuit occurs, a high temperature will be generated instantly in the connecting joint 1. When the temperature sensor 2 detects that the temperature exceeds the threshold, it sends a signal to the electromagnetic control component. After receiving the signal, the electromagnetic control component is energized and generates magnetism, thereby controlling the intermittent transmission component to generate intermittent force. After releasing the squeezing pressure on the multiple first copper busbars 3 and the connecting busbar 5, the connecting busbar 5 can be controlled to deflect relative to the second copper busbar 4, so that the connecting busbar 5 and the first copper busbar 3 can be quickly separated in a short time without being affected by the plastic deformation caused by the long-term pressure of the first copper busbar 3. The circuit can be quickly and automatically cut off or the busbar connection status can be adjusted without relying on external intervention, thereby extending the service life of the electrical equipment and improving the reliability of the busbar conductivity.

[0034] For further solutions to this utility model, please refer to [link / reference]. Figure 6 The second copper busbar 4 has a movable groove 401 at one end away from the busbar for the connecting busbar 5 to rotate, and a deflection shaft 6 that can pass through the movable groove 401 is rotatably mounted on the second copper busbar 4. The deflection shaft 6 is fixed to the multiple connecting busbars 5.

[0035] When one end of the second copper busbar 4 deforms under the pressure of the double-headed bolt, the other end will tend to move in the opposite direction. The two ends of the connecting busbar 5 can always abut against the wall of the movable groove 401, ensuring the connection stability between the connecting busbar 5 and the second copper busbar 4.

[0036] As a further embodiment of this utility model, the electromagnetic control component includes a solenoid valve 7 installed in the connecting section 1, and the solenoid valve 7 establishes communication with the temperature sensor 2;

[0037] It also includes a guide rod 8 installed in the connecting section 1, the guide rod 8 being arranged along the axial direction of the solenoid valve 7, and a slide valve 9 being slidably arranged to be magnetically attracted to the solenoid valve 7.

[0038] It should be noted that a spring must be fitted on the guide rod 8. One end of the spring is connected to the slide valve 9, and the other end is connected to the guide rod 8. When the solenoid valve 7 is de-energized and its magnetism disappears, the slide valve 9 can be reset under the action of the spring, so as to quickly and automatically cut off the circuit when the busbar is short-circuited next time.

[0039] The intermittent transmission component includes a connecting clamp 10 mounted on the slide valve 9, with a first collar and a second collar formed at both ends of the connecting clamp 10.

[0040] It also includes a first drive shaft 11 and a second drive shaft 12 rotatably mounted on the connecting joint 1. The first collar and the second collar are slidably sleeved on the first drive shaft 11 and the second drive shaft 12, respectively. The first drive shaft 11 is connected to the deflection shaft 6 through a rotating component, and the second drive shaft 12 squeezes the connecting row 5 through a pushing component.

[0041] The first sleeve and the second sleeve are respectively rotatably installed with a first ball 1001 and a second ball 1002. The first drive shaft 11 is provided with a first limiting groove 1101 adapted to the first ball 1001, and the second drive shaft 12 is provided with a second limiting groove 1201 adapted to the second ball 1002.

[0042] It should be noted that the first limiting groove 1101 is divided into an A threaded groove and an A straight groove, and the second limiting groove 1201 is divided into a B threaded groove and a B straight groove.

[0043] When the busbar is transmitting power normally, its solenoid valve 7 is in an unenergized state. At this time, the solenoid valve 7 and the slide valve 9 are far apart. Once a short circuit occurs, when the temperature sensor 2 detects that the temperature exceeds the threshold, it will transmit a signal to the control unit. The control unit will send an energizing command to the coil of the solenoid valve 7 according to the preset logic judgment, so that the coil is energized and a magnetic field is generated, thereby attracting the slide valve 9 to move in the direction of the solenoid valve 7, so as to realize the requirement that the slide valve 9 can move.

[0044] In the initial state, the first ball 1001 is located in the straight groove A, and the second ball 1002 is located in the threaded groove B. When the slide valve 9 moves, it can drive the connecting clamp 10 to move synchronously, so that the first ball 1001 and the second ball 1002 move relative to the straight groove A and the threaded groove B, respectively. The second ball 1002 exerts an inclined force on the threaded groove B, so that the second drive shaft 12 rotates when the second ball 1002 moves. At this time, the first drive shaft 11 does not rotate. When the first ball 1001 slides into the threaded groove A, the second ball 1002 slides into the straight groove B. The movement of the first ball 1001 exerts an inclined force on the threaded groove A, so that the first drive shaft 11 rotates when the first ball 1001 moves. At this time, the second drive shaft 12 does not rotate. This achieves the requirement of intermittent transmission between the first drive shaft 11 and the second drive shaft 12. Moreover, the number of rotations of the first drive shaft 11 and the second drive shaft 12 can be controlled by the threads in the threaded grooves A and B.

[0045] For further solutions to this utility model, please refer to [link / reference]. Figure 5 The rotating component includes a connecting shaft 13 rotatably mounted in the connecting joint 1. The two ends of the connecting shaft 13 are respectively connected to the deflection shaft 6 and the first transmission shaft 11 through the first bevel gear set 14.

[0046] The pushing assembly includes a lead screw 16 rotatably installed in the connecting section 1. The lead screw 16 is connected to the second transmission shaft 12 via a second bevel gear set 15. A threaded sleeve 17 is threadedly connected to the lead screw 16. The threaded sleeve 17 is slidably connected to a limiting rod 19 installed in the connecting section 1 and parallel to the axis of the lead screw 16. A pressure plate 18 capable of pressing the connecting row 5 is provided at the end of the threaded sleeve 17 away from the lead screw 16.

[0047] When the first drive shaft 11 rotates, it can drive the deflection shaft 6 to rotate under the transmission of the first bevel gear set 14, so that multiple connecting bars 5 can deflect relative to the second copper bar 4 at the same time, so as to realize the rapid separation of the connecting bars 5 and the first copper bar 3 in a short time, and is not affected by the plastic deformation caused by the long-term pressure of the first copper bar 3.

[0048] When the second drive shaft 12 rotates, it drives the lead screw 16 to rotate under the transmission of the second bevel gear set 15. When the lead screw 16 rotates, it drives the threaded sleeve 17 to move linearly along the axial direction of the lead screw 16. At this time, the two pressure plates 18 simultaneously release the pressure on the connecting row 5, so that the pressure of the multiple connecting rows 5 on the first copper busbar 3 gradually decreases until it disappears, avoiding interference from the pressure plates 18 when the connecting row 5 deflects, thereby realizing the rapid separation of the connecting row 5 and the first copper busbar 3 in a short time.

[0049] It should be noted that by changing the screw ring of the B thread groove and the transmission ratio of the second bevel gear set 15, the problem of insufficient distance for the lead screw 16 to push the threaded sleeve 17 can be effectively solved, ensuring that when the connecting row 5 deflects and separates relative to the first copper row 3, the connecting row 5 and the first copper row 3 are completely separated.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
