Description

Technical Field

[0001] This invention relates to the technical field of transformer substation line loss detection equipment, and in particular to an anomaly detection device for transformer substation line loss. Background Technology

[0002] Distribution transformer area line loss is an important indicator for measuring the economic efficiency and management level of a distribution network. Real-time monitoring and anomaly detection of distribution transformer area line loss helps to promptly identify problems such as line aging, electricity theft by users, and metering equipment failure, ensuring the safe and stable operation of the power grid. Currently, distribution transformer area line loss detection is usually carried out by installing detection devices in the meter boxes, and calculating the line loss rate by collecting voltage and current parameters.

[0003] Existing anomaly detection devices used in transformer substations have the following problems in practical use: First, the testing device is usually fixed inside the meter box by screws, brackets or cable ties. The installation process requires carrying tools and is cumbersome. In addition, the internal dimensions of different models of meter boxes are different, and the existing device is difficult to achieve adaptive fixation. It often requires customized installation brackets for different boxes, which has poor versatility. Second, during transportation or installation, the internal precision measuring components of the testing device are easily affected by external impacts or vibrations, which can lead to component damage or a decrease in measurement accuracy. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems existing in the above and / or existing abnormal detection devices applied to transformer area line loss, the present invention is proposed.

[0006] Therefore, the problem to be solved by the present invention is how to solve the problem that the detection device is usually fixed inside the meter box by screws, brackets or cable ties, which requires carrying tools during the installation process, is cumbersome, and the internal precision measuring elements are easily affected by external impacts or vibrations during transportation or installation, resulting in damage to the elements or a decrease in measurement accuracy.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an abnormal detection device for line loss in transformer substations, comprising: a bottom bearing shell, an upper bearing shell hinged to one side of the bottom bearing shell, a movable cavity inside the bottom bearing shell, an adjustment component fixedly mounted on the outer periphery of the movable cavity, a support component located at the inner corner of the bottom bearing shell, including a sliding cavity, a shaft rod slidably mounted at the top of the sliding cavity, a cam guide ring at the top of the shaft rod, the shaft rod being hollow inside and having a flow hole at its bottom end, a torsion spring at the bottom end of the shaft rod, a bottom shell support component including a sliding plate slidably mounted inside the bottom of the bottom bearing shell, an outlet on one side of the bottom bearing shell corresponding to the position of the bottom shell support component, a folding airbag inside the sliding plate, one end of the folding airbag being fixedly connected to the bottom end of the movable cavity through a pad, and the other end being fixedly connected to the sliding plate, and one end of the folding airbag having a connecting pipe communicating with the adjustment component, and a locking component located inside the upper bearing shell, wherein the adjustment component, in conjunction with the bottom shell support component, can adjust the support strength of the support component.

[0008] As a preferred embodiment of the abnormal detection device for line loss in transformer substations described in this invention, the adjusting component includes: an outer ring, fixedly disposed on the outer periphery of the top end of the movable cavity, with a plurality of positioning holes inside the outer ring; an airbag guide ring, fixedly disposed on the outer periphery of the outer ring, used to fill the gap between the outer ring and the inner wall of the bottom bearing shell, the airbag guide ring being interconnected with the top end of the connecting pipe; and the top end of the shaft rod being inserted into the positioning hole, the outer periphery of the shaft rod being fixedly connected to the cam guide ring.

[0009] As a preferred embodiment of the abnormal detection device for line loss in transformer substations described in this invention, the bottom end of the movable cavity is provided with a sliding groove, a push plate is provided inside the sliding groove, the push plate is fixedly connected to the sliding plate, a rotating groove is provided on both sides of the top end of the push plate, a locking plate is provided inside the rotating groove, and an elastic plate is provided between the rotating groove and the locking plate.

[0010] As a preferred embodiment of the abnormal detection device for line loss in transformer substations described in this invention, the sliding groove is provided with positioning plates on both sides, and the top of the two positioning plates is provided with a plurality of positioning grooves. The locking plate can be inserted into the positioning groove to lock the position of the pushing plate.

[0011] As a preferred embodiment of the abnormal detection device for line loss in transformer substations described in this invention, the locking assembly includes: a drive shaft rotatably disposed inside the upper bearing housing, with bolt rods at both ends of the drive shaft; an extension rod threadedly connected to the outer periphery of the bolt rods, and the extension rod slidably connected to the upper bearing housing, with a connector for external extension rods at the end of the extension rod.

[0012] As a preferred embodiment of the abnormal detection device for line loss in transformer substations described in this invention, it further includes auxiliary components, which include: an external gear ring, fixedly disposed on the outer periphery of the drive shaft; a guide rail, disposed inside the upper bearing housing, a slide plate slidably disposed inside the guide rail, a rack plate on one side of the slide plate that meshes with the external gear ring, and a support spring fixedly connected to the upper bearing housing at the bottom end of the slide plate.

[0013] As a preferred embodiment of the abnormal detection device for line loss in transformer substations described in this invention, the slide plate contacts the bottom bearing shell when the upper bearing shell and the bottom bearing shell are closed, and can push the slide plate to slide upward against the elastic force of the support spring, thereby cooperating with the outer toothed ring and the rack plate to drive the drive shaft to rotate.

[0014] As a preferred embodiment of the abnormal detection device for line loss in transformer substations described in this invention, the sliding cavity is provided with two measuring instruments, each measuring instrument is provided with a remote monitoring component, and the remote monitoring component is connected to the measuring instruments.

[0015] As a preferred embodiment of the abnormal detection device for line loss in transformer substations described in this invention, the upper bearing shell has a lifting plate at its top, a plurality of interface plates at its top, and a plurality of connecting wires at its bottom, which are electrically connected to the measuring instrument.

[0016] As a preferred embodiment of the abnormal detection device for line loss in transformer substations described in this invention, the interface board is used to install three measuring tools, which are clamped and fixed on the outer periphery of the wire.

[0017] The beneficial effects of this invention are: When the sliding plate extends and abuts against the inner wall of the meter box, the airbag is compressed and folded simultaneously. The gas is then delivered to the airbag guide ring through the connecting pipe, realizing the linkage between the sliding plate extension action and the locking action of the support component. This achieves longitudinal fixation and radial gap elimination without additional operation, simplifying the installation process. Secondly, when the upper support shell closes, the sliding plate contacts the bottom support shell and is pushed upward. Through the meshing of the rack plate and the outer gear ring, the drive shaft rotates, causing the extension rod to extend outward and abut against the inner walls on both sides of the meter box. This achieves the linkage between the closing action and the lateral locking, eliminating the need to operate the locking component separately after closing. This ensures that the extension length of the extension rod adapts to the width of the meter box, achieving rapid fixation and anti-theft effects for the equipment.

[0018] Capable of switching between transport shock absorption and installation rigidity modes, the system utilizes a combination of an airbag guide ring, a cam guide ring, and a torsion spring. During equipment movement or handling, the airbag guide ring maintains a low-pressure state, creating a buffer gap between the outer ring and the inner wall of the bottom bearing shell. In the event of an impact, the inner wall of the positioning hole pushes the ring wall of the cam guide ring, causing the shaft rod to rotate or sink, converting the impact energy into dissipated mechanical kinetic energy. Simultaneously, the torsion spring absorbs residual vibration, achieving shock absorption protection and preventing damage to precision components such as internal measuring instruments from impact. Once the equipment is installed in place and the sliding plate extends and is fixed, the folding airbag is compressed, and gas enters the airbag guide ring, causing it to expand and fill the gap between the outer ring and the bottom bearing shell. This switches the outer ring from a floating state to a locked state, eliminating the fit gap between the inner wall of the positioning hole and the cam guide ring. The shaft rod is locked and cannot generate relative movement, ensuring no shaking during equipment operation and improving measurement accuracy. Attached Figure Description

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1, referring to Figures 1 to 7 This is the first embodiment of the present invention. This embodiment provides an anomaly detection device for transformer substation line loss. The anomaly detection device for transformer substation line loss includes a bottom support shell 1, an upper support shell 2, a movable cavity 3, and an adjustment component 4. The bottom support shell 1 and the upper support shell 2 can be tightly fixed together by a lock and fasteners. Together with the bottom shell support 6 and the locking component 7, the device is tightly connected and fixed to the meter box after installation, improving the anti-theft capability of the device. The movable cavity 3 and the adjustment component 4 can switch between two modes: transportation shock absorption and installation rigidity, thereby improving the safety of the device.

[0032] Specifically, the bottom support shell 1 supports the entire device and is placed inside the meter box. An upper support shell 2 is hinged to one side of its upper end. The upper support shell 2 can be flipped open or closed relative to the bottom support shell 1 to facilitate the installation and maintenance of internal components. Simultaneously, the bottom support shell 1 and the upper support shell 2 can be tightly secured together using locks and fasteners, achieving anti-theft protection by locking both shells. The bottom support shell 1 has a movable cavity 3 inside, which accommodates the measuring instrument 9 and other electrical components. An adjustment component 4 is fixed to the outer periphery of the movable cavity 3, which adaptively adjusts the preload of the support component 5 during installation.

[0033] Specifically, the support assembly 5 is located at the inner corner of the bottom bearing shell 1 to provide multi-point support after the device is installed, preventing the device from shaking inside the meter box. The support assembly 5 includes a sliding cavity 51, which is fixedly installed on the inner wall of the bottom bearing shell 1. A shaft rod 52 is slidably provided at the top of the sliding cavity 51, and the shaft rod 52 can move up and down along the axial direction of the sliding cavity 51. A cam guide ring 53 is provided at the top of the shaft rod 52, which is used to cooperate with the adjustment assembly 4 to change its contact state with the adjustment assembly 4 when the shaft rod 52 moves. The shaft rod 52 is hollow inside and has a flow hole 54 at its bottom end. The flow hole 54 allows the air pressure inside the shaft rod 52 to communicate with the air pressure inside the sliding cavity 51, avoiding air resistance when the shaft rod 52 moves. The bottom end of the shaft rod 52 is provided with a torsion spring 55. The bottom end of the torsion spring 55 is fixedly connected to the bottom wall of the sliding cavity 51. When the shaft rod 52 is compressed, the torsion spring 55 undergoes elastic deformation and provides a restoring force after the pressure is released.

[0034] Specifically, the bottom shell support 6 is used to fix the bottom bearing shell 1 inside the meter box. It includes a sliding plate 61 that is slidably disposed at the bottom end inside the bottom bearing shell 1. The sliding plate 61 can reciprocate along the length of the bottom bearing shell 1. An extension opening 62 is provided on one side of the bottom bearing shell 1 corresponding to the position of the bottom shell support 6. One end of the sliding plate 61 can extend out of the bottom bearing shell 1 through the extension opening 62 and abut against the inner wall of the meter box. A folded airbag 63 is provided inside the sliding plate 61. One end of the folded airbag 63 is fixedly connected to the bottom end of the movable cavity 3 through a pad, and the other end is fixedly connected to the sliding plate 61. Therefore, the folded airbag 63 is compressed or stretched when the sliding plate 61 moves. One end of the folded airbag 63 is provided with a connecting pipe 64 that communicates with the adjusting component 4. When the folded airbag 63 is compressed, the gas inside it enters the adjusting component 4 through the connecting pipe 64, causing the adjusting component 4 to expand, thereby increasing the supporting strength of the support component 5.

[0035] Specifically, the locking component 7 is located inside the upper bearing shell 2 and is used to abut against the inner walls of both sides of the meter box after the device is closed, achieving lateral locking. The adjusting component 4, in conjunction with the bottom shell support 6, can adjust the support strength of the support component 5. When the sliding plate 61 extends outward and abuts against the inner wall of the meter box, the folding airbag 63 is compressed, and the gas enters the adjusting component 4 through the connecting pipe 64, causing the adjusting component 4 to apply pressure to the support component 5. Under the pressure, the shaft rod 52 moves downward, the torsion spring 55 is compressed, and the contact surface between the cam guide ring 53 and the adjusting component 4 self-locks, thereby locking the support component 5 in the supported state and preventing the device from shifting inside the meter box.

[0036] Example 2, refer to Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the adjustment component 4 includes: an outer ring 41, fixedly disposed on the outer periphery of the top end of the movable cavity 3, with several positioning holes 42 inside the outer ring 41 for accommodating the top end of the shaft rod 52; and an airbag guide ring 43, fixedly disposed on the outer periphery of the outer ring 41 for filling the gap between the outer ring 41 and the inner wall of the bottom bearing shell 1, with the airbag guide ring 43 connected to the top end of the connecting pipe 64. When the folded airbag 63 is compressed, gas enters the airbag guide ring 43 through the connecting pipe 64, causing the airbag guide ring 43 to expand and apply radial pressure to the outer ring 41, completely filling the gap between the outer ring 41 and the inner wall of the bottom bearing shell 1, thereby eliminating radial shaking of the device within the meter box. The top end of the shaft rod 52 is inserted into the positioning hole 42, and the outer periphery of the shaft rod 52 is fixedly connected to the cam guide ring 53, with the outer ring 41 surface of the cam guide ring 53 slidingly engaged with the inner wall of the positioning hole 42.

[0038] When the equipment is subjected to external impact during handling or movement, the outer ring 41 shakes momentarily relative to the bottom bearing shell 1. The inner wall of the positioning hole 42 is displaced and pushes the ring wall of the cam guide ring 53. Under the push of the inner wall of the positioning hole 42, the cam guide ring 53 drives the shaft rod 52 to rotate or sink axially. The rotation or sinking action of the shaft rod 52 converts the impact energy generated by the impact into mechanical kinetic energy dissipation. At the same time, the torsion spring 55 is compressed or twisted to absorb the remaining impact energy, thereby achieving a shock absorption effect and preventing the impact from being directly transmitted to the precision components such as the measuring gauge 9 inside the movable cavity 3.

[0039] During equipment movement, the air pressure inside the airbag guide ring 43 is low, and a buffer gap is left between the outer ring 41 and the inner wall of the bottom bearing shell 1, allowing the outer ring 41 to float freely within a certain range, further improving the shock absorption performance. When the equipment is installed in place and the sliding plate 61 is extended and fixed, the folding airbag 63 is compressed, and the gas inside enters the airbag guide ring 43 through the connecting pipe 64. The airbag guide ring 43 expands and fills the gap between the outer ring 41 and the bottom bearing shell 1, causing the outer ring 41 to switch from a floating state to a locked state. At this time, the fit gap between the inner wall of the positioning hole 42 and the cam guide ring 53 is eliminated, the shaft rod 52 cannot generate relative movement, and the support assembly 5 maintains a stable support state, ensuring that the equipment does not shake during operation.

[0040] Specifically, the bottom end of the movable cavity 3 is provided with a sliding groove 31, which extends along the length of the bottom bearing shell 1. A push plate 32 is provided inside the sliding groove 31, and the push plate 32 can reciprocate along the sliding groove 31. The push plate 32 is fixedly connected to the sliding plate 61, and the push plate 32 moves synchronously when the sliding plate 61 moves. Rotating grooves 33 are provided on both sides of the top of the push plate 32, and a locking plate 34 is provided inside the rotating groove 33. An elastic plate 35 is provided between the rotating groove 33 and the locking plate 34, and the elastic plate 35 always applies an outward rotational elastic force to the locking plate 34. Positioning plates 36 are provided on both sides inside the sliding groove 31, extending along the length of the sliding groove 31. Several positioning grooves 37 are provided at the top of the two positioning plates 36, and the locking plate 34 can be engaged into the positioning grooves 37 under the elastic force of the elastic plate 35. Once the push plate 32 is in place, the locking plate 34 engages with the corresponding positioning groove 37, locking the position of the push plate 32 and thus locking the extension length of the sliding plate 61. This prevents the sliding plate 61 from accidentally retracting during device use and ensures that the device maintains a stable contact with the inner wall of the meter box.

[0041] Specifically, the locking assembly 7 includes: a drive shaft 71, rotatably mounted inside the upper bearing housing 2, with bolt rods 72 at both ends of the drive shaft 71, the threads of the two bolt rods 72 having opposite directions; and an extension rod 73, threadedly connected to the outer periphery of the bolt rods 72, and slidably connected to the upper bearing housing 2. When the drive shaft 71 rotates, the two extension rods 73 extend outward or retract inward synchronously under the drive of the bolt rods 72. The end of the extension rod 73 is provided with a connector 74 for connecting an external extension rod. When the width of the meter box is large, an extension rod can be connected through the connector 74 to adapt to meter boxes of different specifications.

[0042] Specifically, it also includes auxiliary components 8, which include: an external gear ring 81, fixedly mounted on the outer periphery of the drive shaft 71; a guide rail 82, mounted inside the upper bearing shell 2, the guide rail 82 extending vertically, a slide plate 83 slidably mounted inside the guide rail 82, the slide plate 83 being able to slide up and down along the guide rail 82, a rack plate 84 on one side of the slide plate 83 engaging with the external gear ring 81, and a support spring 85 fixedly connected to the upper bearing shell 2 at the bottom end of the slide plate 83, the support spring 85 always applying an upward elastic force to the slide plate 83, so that the slide plate 83 is held at the top position of the guide rail 82 when not subjected to external force.

[0043] Specifically, the slide plate 83 contacts the bottom support shell 1 when the upper support shell 2 and the bottom support shell 1 are closed. When the upper support shell 2 flips down to close, the bottom end of the slide plate 83 first contacts the upper surface of the bottom support shell 1. As the upper support shell 2 continues to close downward, the slide plate 83 is pushed upward by the bottom support shell 1, overcoming the elastic force of the support spring 85 and sliding upward along the guide rail 82. When the slide plate 83 slides upward, the rack plate 84 drives the outer gear ring 81 to rotate, and the outer gear ring 81 drives the drive shaft 71 to rotate. When the drive shaft 71 rotates, it drives the two extension rods 73 to extend outward synchronously. When the upper support shell 2 is fully closed, the ends of the extension rods 73 abut against the inner walls on both sides of the meter box, realizing the lateral locking of the device. This structure realizes the linkage between the closing action and the lateral locking, eliminating the need to operate the locking component 7 separately after closing, simplifying the installation steps. At the same time, the downward pressure during closing drives the extension rods 73 to extend, ensuring that the extension length of the extension rods 73 is adaptively matched with the width of the meter box.

[0044] Specifically, the sliding cavity 51 is equipped with two measuring gauges 9, which are used to monitor the voltage and current parameters of the transformer area. The measuring gauges 9 are equipped with a remote monitoring component, which is connected to the measuring gauges 9 and is used to send the line loss data collected by the measuring gauges 9 back to the power supply station in real time, so as to realize remote monitoring and abnormal early warning.

[0045] Specifically, the top of the upper support shell 2 is provided with a hinged plate 21, which can be flipped up and opened to facilitate the inspection and maintenance of internal components. The top of the hinged plate 21 is provided with several interface plates 22, and the bottom of the interface plates 22 is provided with several connecting wires. The connecting wires are electrically connected to the measuring instrument 9, and the detection port of the measuring instrument 9 is led out to the outside of the upper support shell 2 through the interface plates 22.

[0046] Specifically, the top of the interface board 22 is equipped with several three-phase measuring tools. These tools are electrically connected to connecting wires and are positioned on the outer periphery of the wire. During use, the tools are clamped onto the exposed portion of the wire being tested. The tools transmit electrical signals to the measuring meter 9 via the connecting wires. The measuring meter 9 analyzes and processes the signals to achieve online detection of line loss in the transformer area. The structural design of the three-phase measuring tools eliminates the need to disconnect the existing wiring during the testing process, reducing the impact of power outages on users and improving both testing efficiency and safety.

[0047] In use, the bottom support shell 1 is first placed inside the bottom of the meter box, and then positioned at the opening of the meter box, so that the bottom of the bottom support shell 1 is locked to the meter box. During the movement or handling of the equipment, the airbag guide ring 43 maintains a low-pressure state, and a buffer gap is formed between the outer ring 41 and the inner wall of the bottom support shell 1. When an accidental impact occurs, the outer ring 41 shakes inside the bottom support shell 1, and the inner wall of the positioning hole 42 pushes the ring wall of the cam guide ring 53. The cam guide ring 53 drives the shaft rod 52 to rotate or sink downward, converting the impact energy into mechanical motion energy for dissipation. At the same time, the torsion spring 55 absorbs residual vibration, achieving shock absorption protection and preventing damage to precision components such as the internal measuring instrument 9 due to impact.

[0048] Then press the two locking plates 34 to make them retract into the rotating groove 33 against the elastic force of the elastic plate 35, thereby releasing the lock on the push plate 32. Then push the sliding plate 61 to move. The sliding plate 61 drives the push plate 32 to slide along the sliding groove 31 until one end of the sliding plate 61 abuts against the inner wall of the meter box. At this time, the locking plates 34 are locked into the corresponding positioning grooves 37 under the elastic force of the elastic plate 35, thus completing the longitudinal installation and locking of the bottom bearing shell 1. During the extension of the sliding plate 61, the folding airbag 63 is compressed, and the gas inside it enters the airbag guide ring 43 through the connecting pipe 64. After the airbag guide ring 43 expands, it fills the gap between the outer ring 41 and the inner wall of the bottom bearing shell 1, so that the outer ring 41 switches from a floating state to a locked state. The fit gap between the inner wall of the positioning hole 42 and the cam guide ring 53 is eliminated, and the shaft rod 52 is locked and cannot generate relative movement. At the same time, the expansion pressure of the airbag guide ring 43 applies radial constraint to the outer ring 41, and the support assembly 5 maintains a stable support state. After installation, the equipment switches to a rigid fixed mode to ensure the measurement accuracy during operation.

[0049] Then, by turning the drive shaft 71 with a wrench, the bolt rods 72 at both ends of the drive shaft 71 are rotated, pushing the extension rod 73 to extend until the extension rod 73 approaches the two inner walls of the meter box.

[0050] Afterwards, the upper bearing shell 2 is closed. During the closing process of the upper bearing shell 2, the sliding plate 83 and the bottom bearing shell 1 come into contact with each other. The sliding plate 83 slides upward against the elastic force of the support spring 85. The rack plate 84 drives the outer gear ring 81 and the drive shaft 71 to rotate, causing the extension rod 73 near the inner wall of the meter box to move further outward, so that the end of the extension rod 73 is tightly abutted against the inner walls on both sides of the meter box. Therefore, when the equipment is fully closed, the device is longitudinally fixed by the bottom shell support 6 and laterally fixed by the locking component 7. It is completely fixed inside the meter box without the need for additional brackets or fasteners. The installation process is simple and quick, and there is no structural damage to the meter box. At the same time, the three measuring tools are clamped on the outer periphery of the wire. The measuring meter 9 collects line loss data in real time, and the remote monitoring component sends the data back to the district power supply station to realize remote online monitoring of line loss in the transformer area.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
