Description

Technical Field

[0001] This utility model relates to the field of railway power line fault detection technology, and more specifically, to a railway power line fault early warning system. Background Technology

[0002] Railway power lines generally use overhead lines, cable lines, or mixed overhead and cable power lines with voltage levels of 35kV and below. These are dedicated lines providing power to railway stations, signaling equipment, communication facilities, and passenger service facilities along the railway line. As one of the core infrastructures of the railway transportation system, railway power lines are the "lifeline" ensuring the safe, efficient, and stable operation of railways. Their importance is reflected in many key areas, directly affecting the overall railway transportation and socio-economic development. A power outage due to a railway power line failure can lead to serious consequences such as signal failure, communication paralysis, and train stoppages, even threatening traffic safety.

[0003] In the existing technology, fault indicators are used to determine and locate faults in overhead and overhead cable mixed power lines. However, the fault indicators have low monitoring accuracy and can only provide a general fault range after a power line fault occurs. Manual line inspection is still required to find the specific fault point, which is extremely inefficient in mountainous or forested areas. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-5 As shown, this embodiment provides a railway power line fault early warning system, including: a main station 10, an indoor device 20, and a conductor device 30. The indoor device 20 is installed in the control panel of the substation 2 and / or the box-type transformer 3. The indoor device 20 is suitable for collecting current and voltage information of the power line and transmitting the current and voltage information to the main station 10. The conductor device 30 is installed on the overhead line 1. The conductor device 30 is suitable for collecting current and voltage information of the power line and transmitting the current and voltage information to the main station 10. The conductor device 30 is equipped with a rotatable solar panel 31.

[0028] In some embodiments, in a power line laid along the railway extension direction, poles 4, distribution boxes and transformer substations 3 are laid out in sequence. Multiple indoor devices 20 and multiple conductor devices 30 are installed on the power line. The conductor devices 30 are installed on the overhead line 1, and the indoor devices 20 are installed in the control panel inside the distribution substation 2 or transformer substation 3. The indoor devices 20 and conductor devices 30 are arranged at intervals of 6km-8km, that is, at a distance of 6km-8km, either an indoor device 20 or a conductor device 30 is installed.

[0029] Understandably, both the indoor device 20 and the conductor-type device 30 can collect current and voltage information of the power line and transmit the collected current and voltage information to the main station 10. The main station 10 analyzes the transmitted current and voltage information to determine whether the power line is faulty. Subsequently, maintenance personnel can accurately and quickly locate the fault point based on the location of the indoor device 20 or the conductor-type device 30, thereby improving the maintenance efficiency of the power line.

[0030] Meanwhile, the wire-type device 30 of this application is equipped with a rotatable solar panel 31. The solar panel 31 can absorb solar energy and convert it into electrical energy that it can use, thereby ensuring the sustainable use of the wire-type device 30, avoiding the need for periodic power supply replacement, and improving the ease of use of the wire-type device 30. Of course, the solar panel 31 of this application can rotate relative to the wire-type device 30. Thus, the solar panel 31 can rotate according to the principle of the sun rising in the east and setting in the west, so that the solar panel 31 can efficiently convert solar energy and improve the utilization efficiency of solar energy.

[0031] It should be noted that the wire-type device 30 is equipped with a storage battery 378, which is electrically connected to the solar panel 31. Thus, the electrical energy converted by the solar panel 31 can be stored in the storage battery 378 to ensure the normal operation of the wire-type device 30 in the case of insufficient light and at night.

[0032] According to the railway power line fault early warning system of this utility model, the fault point of the power line can be accurately and quickly located, thereby improving the maintenance efficiency of the power line. The system issues an early warning when the fault is still in its infancy, so that timely measures can be taken to deal with it and prevent the fault from escalating. At the same time, the conductor-type device 30 of this application is equipped with a rotatable solar panel 31. The solar panel 31 rotates according to the principle of the sun rising in the east and setting in the west, thereby maximizing the utilization of solar energy and ensuring the stable and continuous operation of the conductor-type device 30, thus ensuring the normal operation of the railway power line fault early warning system.

[0033] According to some embodiments of the present invention, a connecting bracket is provided on the top of the wire-type device 30, and a solar panel 31 is rotatably connected to the free end of the connecting bracket. A first driving member 34 is also rotatably connected to the connecting bracket. The first driving member 34 has a retractable first driving end, which is rotatably connected to the solar panel 31.

[0034] In some embodiments, a connecting bracket is provided on the top of the wire-type device 30. The connecting bracket provides an installation base for the solar panel 31 and the first driving member 34. The free end of the connecting bracket is rotatably connected to the solar panel 31, so that the solar panel 31 can rotate relative to the connecting bracket, thereby adjusting the angle of the solar panel 31. The first driving member 34 is also rotatably connected to the connecting bracket. The first driving member 34 has a retractable first driving end, and the first driving end is rotatably connected to the solar panel 31. By extending and retracting the first driving end, the solar panel 31 can be driven to rotate around the rotation connection point between it and the connecting bracket, thereby changing the tilt angle of the solar panel 31.

[0035] It is understandable that the first driving component 34 can be a device capable of generating linear motion, such as an electric push rod or a hydraulic cylinder. When the first driving end of the first driving component 34 extends or retracts, since the first driving end is rotatably connected to the solar panel 31, a force will be generated on the solar panel 31 according to the lever principle and the characteristics of the revolute joint, causing the solar panel 31 to rotate around the rotational connection point between it and the free end of the connecting bracket, thereby realizing the adjustment of the angle of the solar panel 31.

[0036] Therefore, the solar panel 31 can adjust its tilt angle in real time according to the position of the sun, so that the surface of the solar panel 31 is as perpendicular as possible to the sunlight, thereby maximizing the reception of solar radiation energy and improving the conversion efficiency of solar energy.

[0037] According to some embodiments of the present invention, the connecting bracket includes a connecting plate 32, which is rotatably connected to the wire-type device 30. A connecting rod 33 is provided on the side of the connecting plate 32 away from the wire-type device 30. The free end of the connecting rod 33 is rotatably connected to the solar panel 31. The first driving member 34 is rotatably connected to the connecting plate 32.

[0038] In some embodiments, the rotatable connection between the connecting plate 32 and the wire-type device 30 provides a basic dimension of motion for adjusting the angle of the solar panel 31. That is, when installing the wire-type device 30, the operator can control the connecting plate 32 to rotate so that the direction of rotation of the solar panel 31 is from east to west. This ensures that the solar panel 31 can always face the sun when rotating relative to the connecting rod 33, thereby maximizing the utilization of solar energy.

[0039] According to some embodiments of the present invention, a second driving member is provided inside the wire-type device 30. The second driving member has a rotatable second driving end, which extends to connect with the connecting plate 32.

[0040] In some embodiments, the second driving member serves as a power source. When the second driving member is activated, its internal energy conversion mechanism (the second driving member can be a rotating motor that converts electrical energy into mechanical energy) causes the second driving end to rotate. Since the second driving end is connected to the connecting plate 32, according to the principle of mechanical transmission, the rotational power is directly transmitted to the connecting plate 32, causing the connecting plate 32 to rotate around its rotational connection point with the wire-type device 30.

[0041] Therefore, through the above settings, not only can the tilt angle of the solar panel 31 be adjusted by the first driving component 34, but the connecting plate 32 can also be rotated by the second driving component to change the position of the solar panel 31 in the horizontal or other directions, thereby being able to cope with more complex and changeable changes in the position of the sun and further improve the utilization efficiency of solar energy.

[0042] According to some embodiments of the present invention, three conductor-type devices 30 are provided, and the three conductor-type devices 30 are respectively installed on the A line, B line and C line of the overhead line 1, and the three conductor-type devices 30 are connected to each other.

[0043] In some embodiments, the three wire-type devices 30 are configured as a group of wire fault detection mechanisms, with multiple wire fault detection mechanisms spaced apart along the extension direction of the power line. The three wire-type devices 30 are connected to each other to make the fixing of the three wire-type devices 30 more stable, thereby providing a stable mounting base for the solar panel 31 and ensuring the effective rotation of the solar panel 31. It should be noted that the connection between the three wire-type devices 30 is an insulated connection to avoid interference between adjacent wire-type devices 30.

[0044] According to some embodiments of the present invention, a connecting hole is provided on one side of the wire-type device 30 in the width direction, and a detachable connecting rod 33 is provided on the other side of the wire-type device 30 in the width direction. The connecting rod 33 of one wire-type device 30 is received in the connecting hole of another wire-type device 30 to connect two adjacent wire-type devices 30.

[0045] In some embodiments, by housing a detachable connecting rod 33 on one conductor-type device 30 into the connecting hole of another conductor-type device 30, the connection of two adjacent conductor-type devices 30 is realized, thereby enabling three conductor-type devices 30 respectively installed on lines A, B, and C to be connected to each other, so that the three conductor-type devices 30 can jointly withstand certain external forces, such as wind force and line vibration, to maintain a relatively stable positional relationship.

[0046] Furthermore, since the connecting rod 33 is detachable, when a wire-type device 30 malfunctions and needs repair or replacement, it can be easily separated from adjacent wire-type devices 30 without affecting the normal operation of other wire-type devices 30. This means that maintenance personnel can individually inspect or replace the faulty wire-type device 30 and then reconnect it back to the system, improving system maintainability and reducing maintenance difficulty and cost.

[0047] According to some embodiments of the present invention, the connecting rod 33 includes a first rod 35 and a second rod 36. The first rod 35 is connected to the wire-type device 30, and a portion of the second rod 36 is movably inserted into the first rod 35. The second rod 36 is adapted to cooperate with the connecting hole of the wire-type device 30.

[0048] In some embodiments, the second rod 36 is movably inserted within the first rod 35, forming a structure similar to a telescopic sleeve. By controlling the movement of the second rod 36 within the first rod 35, the overall length of the connecting rod 33 can be changed. Preferably, the inner peripheral wall of the first rod 35 is provided with a first thread, and the outer peripheral wall of the second rod 36 is provided with a second thread. Thus, the axial position adjustment of the first rod 35 and the second rod 36 can be achieved by rotating the second rod 36 relative to the first rod 35.

[0049] It is understandable that in actual railway power line installation environments, the installation spacing between conductor-type devices 30 at different locations will vary (different voltages in the power lines will result in different distances between lines A, B, and C). Because the connecting rod 33 of this application has a telescopic function, its length can be flexibly adjusted according to the actual installation spacing, allowing the second rod 36 to be accurately inserted into the connecting hole, ensuring smooth connection of adjacent conductor-type devices 30, and improving the system's installation adaptability and versatility.

[0050] According to some embodiments of the present invention, the conductor-type device 30 is provided with a first current transformer 371, a first voltage transformer 372 and a first communication component. The first current transformer 371 is sleeved on the A line, B line or C line of the overhead line 1. The first voltage transformer 372 is suitable for detecting the voltage of the A line, B line or C line. The first current transformer 371 and the first voltage transformer 372 are respectively connected to the first communication component. The first communication component is communicatively connected to the master station 10.

[0051] In some embodiments, a first current transformer 371 is fitted onto line A, line B, or line C of overhead line 1 to detect the current in line A, line B, or line C based on the principle of electromagnetic induction. A first voltage transformer 372 is disposed within a conductor-type device 30 to detect the voltage in line A, line B, or line C based on the principle of electromagnetic induction or capacitive voltage division. A first communication component can transmit the current detected by the first current transformer 371 and the voltage detected by the first voltage transformer 372 to the main station 10.

[0052] Specifically, the first communication component includes a time synchronization module 373, a storage module 374, a communication module 375, and a central processing module 376. The time synchronization module 373 can directly receive the BeiDou satellite clock signal. The current detected by the first current transformer 371 and the voltage detected by the first voltage transformer 372 are transmitted to the central processing module 376 after passing through the time synchronization module 373. The central processing module 376 processes the above data information and can transmit the processed data information to the communication module 375 and the storage module 374 respectively. The communication module 375 can transmit the processed data information to the main station 10, and the storage module 374 can store the processed data information.

[0053] It should be noted that the battery 378 is electrically connected to the first current transformer 371, the first voltage transformer 372, the time synchronization module 373, the storage module 374, the communication module 375, and the central processing module 376, respectively.

[0054] According to some embodiments of the present invention, a current transformer 377 is also provided inside the conductor-type device 30. The current transformer 377 is sleeved on the A line, B line or C line of the overhead line 1, and the current transformer 377 is connected to the power supply of the conductor-type device 30.

[0055] In some embodiments, the current transformer 377 operates based on the law of electromagnetic induction. When current flows through the overhead line 1, an alternating magnetic field is generated around it. The current transformer 377 is mounted on the line, and its iron core cuts the magnetic field lines of this alternating magnetic field, thereby generating an induced electromotive force in the iron core. After rectification, filtering, and voltage regulation circuits, the induced electromotive force is converted into pulsating direct current to be transmitted to the battery 378 (the battery 378 is the power source for the wire-type device 30).

[0056] According to some embodiments of the present invention, the indoor device 20 includes a second current transformer 21, a second voltage transformer 22, and a second communication component 23 connected to each other. The second communication component 23 is communicatively connected to the master station 10 and is adapted to transmit the current of the power line detected by the second current transformer 21 and the voltage of the power line detected by the second voltage transformer 22 to the master station 10.

[0057] In some embodiments, the second current transformer 21 detects the current of line A, line B or line C based on the principle of electromagnetic induction, and the second voltage transformer 22 detects the voltage of line A, line B or line C based on the principle of electromagnetic induction or capacitive voltage division. The second communication component 23 can transmit the current detected by the second current transformer 21 and the voltage detected by the second voltage transformer 22 to the main station 10.

Various modifications and variations can be made to this utility model by those skilled in the art.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
