Description

Technical Field

In the smart grid environment, high and low voltage electrical equipment, as an important part of the power system, its operating status directly affects the stable operation of the entire power grid.

[0003] Currently, high- and low-voltage electrical equipment is typically equipped with circuit breakers to ensure the safe operation of power systems. However, existing monitoring methods have limitations, making it difficult to accurately monitor the instantaneous opening and closing states of circuit breakers in real time. This prevents personnel from timely and comprehensive understanding of the circuit breaker's operating status, making it difficult to quickly implement effective countermeasures. Once this occurs, the power supply is likely to be interrupted, affecting not only the normal operation of electrical equipment but also the normal use of electricity by users.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] In order to solve the problem that the current in the circuit protected by the circuit breaker 6 exceeds the rated current of the circuit breaker, and the line is broken due to aging of the wires, and to avoid the problem that monitoring, feedback and processing cannot be carried out in time after the trip, so as to prevent it from affecting the power supply, causing damage to electrical equipment, and thus affecting the stable use of electricity, such as Figures 1-12 As shown, the following preferred technical solutions are provided:

[0035] A big data-based background monitoring device for high- and low-voltage electrical equipment includes a high- and low-voltage distribution cabinet 1, an adjustment frame 2 mounted on the cabinet 1, and a monitoring device 3 mounted on the adjustment frame 2. The adjustment frame 2 is mounted on the cabinet 1 to provide an adjustable mounting position for the monitoring device 3. The adjustment frame 2 is typically designed using a mechanical structure, such as a screw or slider, to electrically adjust the position of the monitoring device 3 so that it can accurately monitor the required electrical parameters. The presence of the adjustment frame 2 enables the monitoring device 3 to adapt to different installation environments and monitoring requirements, improving the flexibility and applicability of the device. A monitoring assembly 4 is provided on the monitoring device body 3. The monitoring assembly 4 includes a collar frame 41 fixedly connected to the monitoring device. A fixing plate 42 is fixedly connected to the side wall of the collar frame 41. A mounting box 43 is fixedly connected to the side wall of the fixing plate 42. A circuit breaker 6 is installed on the high and low voltage distribution cabinet 1. A conductive contact 63 is installed inside the circuit breaker 6. The conductive contact 63 is an important component for current transmission. The conductive contact 63 is usually made of a material with good conductive properties, such as copper or aluminum, to ensure that the current can pass smoothly. The conductive contact 63 contacts the conductive contact 73 to achieve the conduction and disconnection of the circuit. A conductive contact 73 is installed on the conductive contact 63. The conductive contact 73 works in conjunction with the static contact 62 to ensure stable current transmission. When a circuit fault occurs, the conductive contact 73 will separate from the static contact 62 to cut off the circuit. An inlet 66 is formed on the side wall of the circuit breaker protector 6 , and an elastic blocking plate 67 is installed on the inner wall of the circuit breaker protector 6 . The elastic blocking plate 67 fits in place with the inlet 66 .

[0036] The top surface of the mounting box 43 is fixedly connected to a support 44, to which a sleeve 45 is fixedly connected. A slide bar 47 is slidably connected inside the sleeve 45. A spring 46 is fixedly connected to the side wall of the sleeve 45. The other end of the spring 46 is fixedly connected to the slide bar 47. A detection probe 48 is fixedly connected to the bottom of the slide bar 47. The detection probe 48 is in contact with the conductive contact 73. The detection probe 48 can monitor the conductive properties, temperature, and other parameters of the conductive contact 73 in real time to ensure that the required data can be accurately collected. The detection probe 48 transmits the collected data to the monitoring device body 3, which is analyzed and processed by the monitoring device body 3.

[0037] A tripper 61 is rotatably mounted on the circuit breaker 6 , a static contact 62 is mounted inside the circuit breaker 6 , a backup power supply 64 is mounted on the side wall of the circuit breaker 6 , and an electric push rod 65 is mounted on the circuit breaker 6 , which is electrically connected to the backup power supply 64 .

[0038] Specifically, in the smart grid industry, various types of power equipment are widely used, including high-voltage distribution cabinets, low-voltage distribution cabinets, etc. Power equipment is generally equipped with a circuit breaker protector 6. When the power equipment is in use, if the current is too large or the voltage exceeds the normal working range, the circuit breaker protector 6 can quickly capture the abnormal current signal and decisively cut off the circuit in a very short time, thereby effectively protecting the power equipment.

[0039] However, in actual use, the circuit breaker protector 6 also faces some problems. When the power grid has unstable voltage or excessive current, the trip device 61 on the circuit breaker protector 6 will trip frequently. The frequent operation of the trip device 61 will cause the arc temperature generated between the static contact 62 and the conductive contact 63 to rise sharply, thereby causing damage to the contact. Once the contact is damaged, it will seriously affect the normal conduction of electricity, and ultimately interfere with the normal operation of the power equipment.

[0040] In order to monitor and deal with the above problems in a timely manner, Figure 1 As shown, a monitoring device body 3 with an adjustment frame 2 is installed on the high and low voltage distribution cabinet 1. The adjustment frame 2 has the function of flexibly adjusting the position of the monitoring device body 3 in the vertical and horizontal directions (this technology belongs to the existing technology and will not be elaborated on here). With the help of the monitoring device body 3, the circuit breaker 6 can be monitored in all directions. When the tripping of the release 61 occurs due to excessive current or unstable voltage, the monitoring device body 3 will quickly scan and perceive the status of the circuit breaker 6, and use big data to conduct in-depth analysis of it. Subsequently, the analysis results are transmitted to the background monitoring end by outputting signals so that the staff can obtain information in a timely manner and quickly go to the scene for processing.

[0041] In addition, when the state of the circuit breaker 6 is scanned to change, since an entrance 66 is pre-opened on the side wall of the circuit breaker 6, the monitoring device body 3 will immediately drive the detection component, replacement component 5, etc. to enter the entrance 66 through the adjustment frame 2. In the process of entering the entrance 66, the elastic blocking plate 67 is flipped upward by the external force, which provides convenience for the monitoring device body 3 to quickly enter the interior of the circuit breaker 6.

[0042] like Figure 2-4As shown, as the detection component enters, the detection probe on the detection component will contact the conductive contact 73. The conductivity of the conductive contact 73 can be accurately detected through the detection probe. When the test result shows that the conductivity of the conductive contact 73 has not decreased, it can be determined that the conductive contact 73 can still continue to be used normally.

[0043] At this time, the detection probe 48 will transmit the detected signal to the backup power supply 64 and the electric push rod 65. After the backup power supply 64 transmits current to the electric push rod 65, the electric push rod 65 starts and extends outward. Since the tripper 61 is installed in the vertical direction of the electric push rod 65, the electric push rod 65 will resist the tripper 61 during the extension process, causing the tripper 61 to rotate under force, thereby driving the conductive contact 63 connected by the spring 46, armature, etc. to reset. After the conductive contact 73 on the conductive contact 63 is reset, it contacts the static contact 62, successfully connecting the circuit and realizing automatic reset, effectively avoiding the adverse effects of the circuit breaker 6 on the stable power supply caused by the untimely recovery after the trip.

[0044] In order to solve the technical problem that the conductive contact 73 in the circuit breaker 6 is damaged due to frequent contact with the static contact 62, resulting in an increase in arc temperature, and cannot be replaced in time, thereby causing the power supply to be unable to be restored in time, such as Figures 1-12 As shown, the following preferred technical solutions are provided:

[0045] The replacement assembly 5 is installed within the installation box 43. The replacement assembly 5 includes a cavity 51 defined within the installation box 43. A panel 55 is fixedly connected within the cavity 51 to protect and position a spare contact 56. The spare contact 56 is placed in the center of the panel 55. Spare contact 56 is used to replace damaged conductive contact 73. Made of a material with excellent electrical conductivity, spare contact 56 ensures proper current flow after connection to the circuit. Cavity 51 provides mounting space for components such as the panel 55 and the electric push rod 52, and also serves as a storage area for spare contact 56.

[0046] Conductive contact 63 houses a clamping assembly 7, which includes a hole 74 formed on the conductive contact 63. A fixed clamp ring 76 and a movable clamp ring 78 are mounted within hole 74. Hole 74 serves as the mounting location for the contact. The size and shape of hole 74 match the contact, ensuring it fits securely within the hole.

[0047] An electric push rod 52 is fixedly connected to the cavity 51. The output end of the electric push rod 52 is fixedly connected to a connecting block 53. A sealing plate 54 is fixedly connected to the end side of the connecting block 53. The top surface of the sealing plate 54 is in contact with the bottom surface of the spare contact 56. In the initial state, the sealing plate 54 blocks the material opening at the bottom of the storage box, preventing the spare contact 56 from falling. When the contact needs to be replaced, the electric push rod 52 pushes the connecting block 53, which in turn drives the sealing plate 54 to slide horizontally along the bottom surface of the cavity 51, exposing the material opening, allowing the spare contact 56 to fall into the leak hole 74.

[0048] The bottom of the mounting box 43 is fixedly connected to a resistance rod 57, and the bottom of the fixing plate 42 is fixedly connected to an L-shaped frame 71. A placement slot 72 is provided on the L-shaped frame 71. The conductive contact 73 is in the same vertical direction as the placement slot 72. The side wall of the U-shaped frame 77 is fixedly connected to a protruding rod 710. The protruding rod 710 and the resistance rod 57 are coaxially arranged in the same horizontal plane. When the mounting box 43 slides into the circuit breaker protector 6, the resistance rod 57 will move horizontally synchronously. When it moves to contact with the protruding rod 710, it will apply a resistance force to the protruding rod 710. A sliding groove 75 is provided on the conductive contact piece 63. The sliding groove 75 is connected to the leakage hole 74, and the fixing clamp ring The clamp 76 is fixedly connected to the inner wall of the slide groove 75. A U-shaped frame 77 is slidably connected within the fixed clamp ring 76. The U-shaped frame 77 is fixedly connected to the movable clamp ring 78. The movable clamp ring 78 is slidably connected to the slide groove 75. The slide groove 75 provides a sliding track for the movable clamp ring 78 and the U-shaped frame 77, allowing the movable clamp ring 78 to slide freely within the slide groove 75, thereby achieving the clamping and releasing operations of the contacts. A compression spring 79 is sleeved on the U-shaped frame 77. The two ends of the compression spring 79 are respectively fixedly connected to the inner walls of the fixed clamp ring 76 and the movable clamp ring 78 on the adjacent sides. A through groove 711 is formed on the side wall of the conductive contact 63. The U-shaped frame 77 is slidably connected to the through groove 711. The through groove 711 limits and guides the movement of the U-shaped frame 77, ensuring that the U-shaped frame 77 can slide accurately along the direction of the through groove 711 when subjected to external force, thereby ensuring that the movable clamp ring 78 can correctly separate from or clamp the contact.

[0049] Specifically, such as Figure 3-Figure 5 as well as Figures 8-12 As shown, during the process of the detection probe 48 and the replacement component 5 entering (as shown Figure 2-Figure 7 As shown in the figure, the detection probe on the detection component will contact the conductive contact 73. After the detection probe 48 contacts the conductive contact 73, its conductivity can be detected. Once the conductivity of the conductive contact 73 is detected to have decreased, it can be determined that the conductive contact 73 cannot be used any more. Since the staff is in the background monitoring, when they receive the signal that the power equipment has tripped due to a short circuit, they cannot quickly arrive at the scene to replace the conductive contact 73. This results in the electrical equipment connected to the power equipment being unable to obtain power supply in time, thereby affecting the stable supply of electricity.

[0050] Therefore, after detecting that the conductive contact 73 is damaged, it is necessary to continue to drive the monitoring device so that it drives the detection probe 48 to continue to slide into the circuit breaker 6. When the detection probe 48 continues to slide and contacts the inner wall of the circuit breaker 6, since the detection probe 48 is fixed on the slide bar 47, and the slide bar 47 is slidably connected in the sleeve 45, when the detection probe 48 encounters resistance, it will drive the slide bar 47 to slide into the sleeve 45. As the slide bar 47 slides, it will squeeze the spring 46 installed on its side wall. Because the detection probe 48 is installed on the installation box 43, the installation box 43 will not be affected by the detection probe 48 during the continuous entry process.

[0051] like Figures 3 to 5 As shown, since the interference rod 57 is fixedly connected to the installation box 43, and the interference rod 57 and the protruding rod 710 are coaxially arranged horizontally, during the sliding entry of the installation box 43, the interference rod 57 will move horizontally synchronously. When the interference rod 57 moves to contact the coaxially arranged protruding rod 710, the protruding rod 710 will be subjected to the interference force. Since the protruding rod 710 is fixedly connected to the U-shaped frame 77, and the U-shaped frame 77 is slidably connected to the fixed clamping ring 76, the protruding rod 710 will drive the U-shaped frame 77 to slide into the through groove 711 when the force is applied, and the U-shaped frame 77 will slide in the movable clamping ring 78. Because the movable clamping ring 78 is fixedly connected to the U-shaped frame 77, during the sliding process of the U-shaped frame 77 (as shown in FIG. Figure 1 and Figure 12 As shown), the movable clamp ring 78 will slide in the slide groove 75 along with the U-shaped frame 77, thereby separating the movable clamp ring 78 from the conductive contact 73 placed in the leak hole 74, thereby releasing the limit on the conductive contact 73.

[0052] Since the conductive contact 73 and the placement slot 72 on the L-shaped frame 71 are in the same vertical direction, when the conductive contact 73 is released from the limit, it will fall into the placement slot 72 on the L-shaped frame 71 (as shown in FIG. Figure 3-Figure 5 、 Figure 11-12As shown), as the conductive contact 73 falls, the leakage hole 74 in the conductive contact piece 63 will be exposed. At this time, the electric push column 52 is started, and the electric push column 52 extends to drive the blocking plate 54 on the connecting block 53 to slide horizontally along the bottom surface of the cavity 51. As the blocking plate 54 continues to slide, since the bottom of the placement box is provided with a material opening, and the material opening was originally blocked by the blocking plate 54, when the blocking plate 54 slides, the material opening at the bottom of the placement box will be exposed. Since the spare contact 56 and the leakage hole 74 are on the same axis, when the material opening is exposed, the spare contact 56 will fall into the leakage hole 74, and the spare contact 56 will be resisted by the conductive contact 73 that has fallen into the placement slot 72, thereby The spare contact 56 is made to fall stably into the leak hole 74 without falling. After the spare contact 56 falls steadily, the installation box 43 on the monitoring equipment body 3 is controlled by the adjustment frame 2 to slide out of the circuit breaker protector 6. As the installation box 43 moves, the interference rod 57 fixed thereto will be separated from the protruding rod 710. Since a compression spring 79 is provided between the movable clamping ring 78 and the fixed clamping ring 76, at the moment when the interference rod 57 is separated from the protruding rod 710, the compression spring 79 will use its own elasticity to drive the movable clamping ring 78 to quickly reset and fit on the side wall of the spare contact 56, thereby clamping and fixing the spare contact 56, ensuring that the spare contact 56 can be stably installed for subsequent use.

[0053] like Figure 3 As shown, as the installation box 43 continues to slide out, the detection probe 48 fixed thereto will also slide out. During the sliding process, since the detection probe 48 is no longer in contact with the inner wall of the circuit breaker protector 6, the spring 46 will use its own performance to drive the detection probe 48 to slide out. When the detection probe 48 slides out, it will contact the replaced spare contact 56 again. The replaced spare contact 56 can be detected by the detection probe 48 to determine whether it is installed well. When it is detected that the conductive performance of the spare contact 56 is good, a signal will be transmitted to the backup power supply 64 and the electric push rod 65. The backup power supply 64 transmits current to the electric push rod 65, and the electric push rod 65 starts after receiving the current. And extend outward. Since the tripper 61 is installed in the vertical direction of the electric push rod 65, the electric push rod 65 will contact the tripper 61 during the extension process, causing the tripper 61 to rotate under force, thereby driving the conductive contact 63 connected by the spring 46, the armature, etc. to reset, so that the spare contact 56 on the conductive contact 63 is reset and contacts the static contact 62, connecting the circuit and realizing automatic reset. This not only avoids the impact of the circuit breaker protector 6 not recovering in time after tripping on the stable power supply, but also takes backup remedial measures for the situation where maintenance personnel cannot arrive in time, thereby ensuring the normal power supply of power equipment and reducing the impact of electrical equipment due to long-term power outages.

[0054] As the monitoring device body 3 continues to slide, when it completely slides out of the circuit breaker 6, the resistance force on the elastic blocking plate 67 disappears, and it will automatically rotate downward to reset, thereby blocking the entrance 66 and preventing the circuit breaker 6 from causing a short circuit due to long-term exposure.

[0055] It should be noted that, when monitoring the circuit breaker 6, the monitoring process is not only for the case of power outage and tripping. In daily use, regular detection can also be carried out according to the above steps to ensure that the power equipment can operate normally and stably.

[0056] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
