The compensation capacitor is an important device to ensure that the track circuit can realize the broken rail detection function.

[0003] Since the compensating capacitors installed near the railroad sleepers are used in an extremely harsh environment, there are not only large vibration shocks, but also adverse factors such as the temperature difference between day and night and humidity changes in different regions, which can cause the compensating capacitors to deteriorate or be damaged. In addition, since the lead wires of the capacitors have a large span, if stones or ice cubes driven by the bottom of the train directly hit the compensating capacitors during the running of the train, it is easy to cause the lead wires of the capacitors to break, break, introduce track circuit short circuits and other faults, thus requiring frequent replacement of the entire compensating capacitor equipment. Due to the inconvenient environmental conditions, the maintenance of the compensating capacitors is very difficult and requires a lot of man-hours, which seriously affects the order of railway transportation.

[0034] In order to enable people in the technical field to better understand the present solution, the technical solution in the embodiment of the present solution will be clearly described below in conjunction with the drawings in the embodiment of the present solution. Obviously, the described embodiment is an embodiment of a part of the present solution, not all of the embodiments. Based on the embodiments in the present solution, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present solution.

[0035] The term "including" and any other variations in the specification and claims of this solution and the above drawings mean "including but not limited to", and is intended to cover non-exclusive inclusions and is not limited to the examples listed in the text. In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.

[0036] Track compensation capacitor equipment is a capacitor device used in high-speed and ordinary speed ZPW2000 track circuits. A track compensation capacitor device can be set every 50m-60m between two rails. The track compensation capacitor equipment currently in use usually adopts an integrated structure, that is, two lead wires for connecting the external track are integrated with the circular capacitor chip as a whole. The track compensation capacitor of this structure needs to be installed near the external sleeper through another fixing device, and its two lead wires also need to pass through the bottom of the two rails, and the two lead wires are connected to the external track respectively through plug nails or terminal blocks.

[0037] Once the track capacitor fails, the entire track capacitor needs to be replaced. However, due to the complex and harsh environmental conditions near the railway line, the equipment damage rate of the track capacitor is extremely high, so the track capacitor needs to be replaced frequently, and the on-site removal operation is difficult and poses a great safety hazard.

[0038] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings:

[0039] Figure 1 This is a schematic diagram of the structure of a track compensation capacitor device 100 provided in an embodiment of the present disclosure. Figure 2 Schematic diagram of the structure of a track compensation capacitor device provided by another embodiment of the present disclosure. Figure 1 and Figure 2 , the track compensation capacitor device 100 comprises:

[0040] A plurality of capacitor chips 101 , a capacitor connecting sheet 102 , a socket 103 , a plug 104 , a lead wire 105 , a plurality of partition positioning grooves 106 and a plurality of capacitor partitions 107 .

[0041] The plurality of capacitor chips 101 are arranged in sequence and form a flat structure.

[0042] The plurality of capacitor chips 101 are all connected to the capacitor connecting sheet 102 . The capacitor connecting sheet 102 is connected to the socket 103 .

[0043] The socket 103 is connected to the plug 104. The plug 104 is connected to the lead wire 105. The lead wire 105 is used to connect to the external rail 200.

[0044] A plurality of partition plate positioning grooves 106 are respectively disposed between every two capacitor chips. Two partition plate positioning grooves 106 are symmetrically disposed between every two capacitor chips.

[0045] A plurality of capacitor spacers 107 are respectively disposed at the spacer positioning grooves between every two capacitor chips.

[0046] In this embodiment, multiple capacitor chips 101 are the core components of the entire device, and are electronic chips responsible for storing and releasing electrical energy. Among them, multiple capacitor chips 101 can be composed of n small-diameter capacitor chips with 1 / n capacitance, and multiple capacitor chips 101 are arranged in parallel in sequence. In order to enable the capacitor chip to fit the shape of the external sleeper 300 for easy fixation, multiple capacitor chips 101 can form a capacitor array with a flat structure. This structural design can make the capacitor chip occupy less space and improve space utilization, and is particularly suitable for installation in space-constrained environments, such as tunnels, underground, high-density electrical cabinets or railway sleepers.

[0047] The flat trapezoidal structure may include multiple heat dissipation surfaces, which increase the contact area with the air, facilitate the natural convection of heat energy, maintain the smooth heat dissipation of the capacitor chip under high load, and extend the service life. The flat trapezoidal structure facilitates the arrangement of capacitor chips on the circuit board, and it is easy to realize the series or parallel connection of multiple capacitor chips 101 to adjust the total capacitance value to meet different voltage or current compensation requirements. The flat trapezoidal structure enhances the mechanical stability of the capacitor chip, and can maintain good electrical contact and reduce the failure rate even in the vibration and impact during rail transportation, installation or operation. The flat trapezoidal structure is conducive to the integration of multiple capacitor chips 101 and components such as capacitor connecting sheets 102, simplifies the assembly process, improves the modularity of the overall equipment, and is easy to maintain and replace.

[0048] The capacitor connecting plate 102 is a bridge between each capacitor chip and other components. The capacitor connecting plate 102 is a conductive metal device. Multiple capacitor chips 101 are connected to the capacitor connecting plate 102 to ensure that each capacitor chip can realize the flow of electrical signals with components in other parts.

[0049] The capacitor connecting piece 102 is connected to the socket 103, and the socket 103 provides a fixed power supply position. The socket 103 is used in conjunction with the plug 104, and the plug 104 is connected to the lead wire 105. The lead wire 105 is a cable for transmitting electrical signals, usually including a tinned copper conductor, an isolation layer, a rubber insulator, and a butyl rubber sheath layer. The plug 104 and the lead wire 105 adopt an integral injection molding process to ensure the waterproof seal of the plug 104 and the lead wire 105.

[0050] By cooperating between the plug 104 and the socket 103, the traditional connection method between the lead wire 105 and the capacitor integrated structure is changed, avoiding the need to replace the entire track compensation capacitor device 100 due to failure of some components, thereby reducing the replacement frequency of the track compensation capacitor device 100 and reducing the difficulty of maintenance.

[0051] In this embodiment, a plurality of capacitor chips 101 are connected to the socket 103 through a capacitor connecting sheet 102, and a plug 104 is connected to the socket 103 together with a lead wire 105. In this process, the socket 103 and the plug 104 can be in a connected state or a disconnected state. When the socket 103 and the plug 104 are connected, that is, the track compensation capacitor device 100 is put into use, and the lead wire 105 transmits the electric energy of the plurality of capacitor chips 101 to the external track 200, so as to realize the inductive compensation of the external track 200. When the socket 103 and the plug 104 are disconnected, that is, the track compensation capacitor device 100 is cut out, and the inductive compensation for the external track 200 is stopped at this time.

[0052] In this embodiment, two partition positioning grooves 106 can be symmetrically arranged between every two capacitor chips. This symmetrical layout is intended to provide a precise positioning guide and support structure to ensure that a fixed distance is maintained between every two capacitor chips, reserving space for the subsequent installation of capacitor partitions, and also facilitating the formation of heat dissipation airflow channels.

[0053] Each capacitor spacer 107 is placed at the spacer positioning groove between every two capacitor chips. These capacitor spacers may have insulation and / or heat dissipation properties. On the one hand, they prevent electrical short circuits between multiple capacitor chips 101, and on the other hand, they serve as heat conduction media to help dissipate heat from multiple capacitor chips 101. Through this design, the capacitor chips are not only physically arranged stably with fixed spacing, reducing potential physical or electrical interference, but also optimized in terms of thermal management, which is conducive to long-term stable operation in an optimal state and reducing heat accumulation.

[0054] It can be concluded from the above that this embodiment can be distinguished from the traditional integrated connection method, and adopts a separate connection method, through the socket 103 and the plug 104, the lead wire 105 is separately connected to the multiple capacitor chips 101. If there is a fault in both, they can be replaced or repaired separately, reducing the difficulty of maintenance and the number of replacements for the entire track compensation capacitor device 100. This embodiment also designs a flat trapezoidal capacitor chip, which not only optimizes the space utilization of the track compensation capacitor device 100, but also improves the performance of the device, enhances the stability of the device and the convenience of maintenance.

[0055] Figure 3 is a schematic diagram of the installation of the track compensation capacitor device provided by the embodiment of the present disclosure, referring to Figure 3 In one embodiment of the present disclosure, the track compensation capacitor device 100 further includes:

[0056] Capacitor housing and fixing ears.

[0057] A plurality of capacitor chips, capacitor connecting pieces and sockets are all arranged in the capacitor housing. The capacitor housing is a flat trapezoidal structure.

[0058] The capacitor housing is mounted on the outer sleeper 300 via fixing ears.

[0059] In this embodiment, in order to ensure that the multiple capacitor chips 101 are not damaged by the external environment as much as possible, the multiple capacitor chips 101 can be protected by a capacitor housing. The capacitor housing is a containing body and can be designed as a flat trapezoidal structure. The structure can make full use of the concave platform of the cross section of the external sleeper 300, so that it can be installed on the external sleeper 300, adapted to the shape structure of the multiple capacitor chips 101, optimize the spatial layout, and better accommodate multiple capacitor chips 101. The structure is also conducive to heat dissipation and maintenance, reduces wind resistance, and at the same time improves the protection level against the outside world, prevents dust and moisture from intruding, and increases the durability of the equipment. Among them, multiple capacitor chips 101, capacitor connecting pieces 102, and sockets 103 are all arranged inside the capacitor housing.

[0060] In this embodiment, the capacitor housing and the socket 103 can be designed in an integrated manner, and the fixing ears are used as a bridge for directly connecting the capacitor housing and the external track 200. Fasteners such as screws or other fixing methods are used to enable the track compensation capacitor device 100 to be firmly installed beside the sleepers or tracks, ensuring the accurate positioning and stability of the device and avoiding vibration or accidental movement. This design is also convenient for installation and disassembly, and is convenient for maintenance or replacement of the device.

[0061] It can be concluded from the above that the present embodiment can provide physically integrated protection for the track compensation capacitor device 100 and ensure stable installation of the device at the track site, thereby enhancing the overall durability and maintenance convenience of the track compensation capacitor device 100, adapting to the harsh conditions of the track environment, and ensuring the long-term and effective operation of the capacitor device.

[0062] In one embodiment of the present disclosure, the socket 103 is disposed inside the capacitor housing in a diagonal direction.

[0063] In this embodiment, in order to facilitate the actual installation of the track compensation capacitor device 100 and to make full use of the limited rail space, the socket 103 can be arranged inside the capacitor housing in a diagonal direction. In this way, both ends of the track compensation capacitor device 100 can be connected to the plug 104, making full use of the limited installation space of the device on the external sleeper 300, and also playing a certain fixing role.

[0064] It can be concluded from the above that the present embodiment can reasonably utilize the space of the external sleeper 300, so that the track compensation capacitor device 100 is more adaptable to the railway environment.

[0065] Reference Figure 3 In one embodiment of the present disclosure, the track compensation capacitor device 100 further includes:

[0066] Plug nail 109.

[0067] The plug pins 109 are installed on both sides of the capacitor housing. The plug pins 109 are fixed on the outer sleeper 300 at a first angle.

[0068] In this embodiment, the pin 109 is an important component for better fixing the capacitor housing to the external sleeper 300. The pin 109 can fix the capacitor housing to the external sleeper 300 at a first angle during the installation process.

[0069] For example, the lead wire 105 can extend from the plug 104 to the external track 200, and be connected to the external sleeper 300 by the plug pin 109 in a 45° inclined installation mode, so as to ensure that the track compensation capacitor device 100 can be connected to the track circuit to compensate or adjust the electric energy. This plug pin 109 connection mode can reduce the usage of the lead wire 105 by 40%, and at the same time reduce the torsional stress of the root of the plug pin 109 caused by train vibration, thereby increasing the life of the lead wire 105.

[0070] It can be concluded from the above that the present embodiment can firmly fix the track compensation capacitor device 100 on the external sleeper 300 by means of the pins 109, thereby ensuring that it will not deviate from the track when subjected to severe vibration, thereby extending its service life as much as possible.

[0071] In one embodiment of the present disclosure, self-elastic locking hooks are provided on both sides of the plug 104. Locking holes are provided on both sides of the socket 103.

[0072] In this embodiment, in order to prevent the socket 103 from being disconnected from the plug 104 and affecting the normal operation of the external track 200, self-elastic lock hooks can be set on both sides of the plug 104, and unlocking holes can be set on both sides of the socket 103. The plug 104 and the socket 103 are arranged horizontally in a manner suitable for flat capacitors. When the plug 104 is inserted into place, the self-elastic lock hook will automatically pop out to achieve a quick connection between the plug 104 and the socket 103, and form a physical locking mechanism between the socket 103 and the plug 104. Such a design makes the connection between the plug 104 and the socket 103 more secure, and it is not easy to fall off even under vibration or external force, which improves the stability of the connection and ensures the continuity of power transmission.

[0073] When the socket 103 needs to be disconnected from the plug 104, matching unlocking holes are designed on both sides of the socket 103. The socket 103 can be disconnected from the plug 104 through the unlocking holes, thereby avoiding wrong plugging and unplugging operations.

[0074] A silicone sealing ring may also be provided at the root of the plug 104 , and the sealing ring may be compressed and deformed by the self-locking mechanism of the plug 104 and the socket 103 , thereby realizing the waterproof function of the plug interface.

[0075] It can be concluded from the above that this embodiment can ensure the tightness of the connection between the socket 103 and the plug 104, can effectively avoid poor contact caused by loose connection during the long-term use of the track compensation capacitor device 100, and improve the reliability and safety of the entire device.

[0076] Reference Figure 2 In one embodiment of the present disclosure, the track compensation capacitor device 100 further includes:

[0077] A plurality of tack welding holes 108 .

[0078] A positioning welding hole 108 is arranged between every two capacitor chips. The spacings between the plurality of positioning welding holes 108 are equal.

[0079] In this embodiment, a positioning welding hole 108 is provided between each two capacitor chips so that two adjacent capacitor chips can maintain a fixed spacing. The positioning welding hole 108 provides a fixed reference point, and the capacitor chip is firmly fixed to the bottom plate or the bracket by welding. This not only ensures that the fixed distance between the capacitor chips is consistent, which is beneficial to heat dissipation and air flow between capacitor chips, but also improves the stability of the overall structure and prevents displacement caused by vibration.

[0080] The tin-penetrating function of the welding hole can improve the reliability of welding between the capacitor connecting piece and the capacitor core, and can also ensure the positioning and spacing of each capacitor core, and maintain the distance between each capacitor core and the inner cavity of the shell, so that the vacuum potting resin can completely and effectively wrap each core, thereby improving the capacitor process level.

[0081] It can be concluded from the above that this embodiment can physically enhance the installation stability of the capacitor chip and can also ensure the long-term stability, reliability and durability of the track compensation capacitor device 100 in track applications.

[0082] In one embodiment of the present disclosure, the track compensation capacitor device 100 further includes:

[0083] Capacitor buffer.

[0084] The capacitor buffer is used to connect to the external track 200. The capacitor buffer is connected to each capacitor chip respectively.

[0085] In this embodiment, the capacitor buffer is configured to absorb voltage fluctuations of the external rail 200 and play a buffering role to prevent the unstable voltage of the external rail 200 from directly impacting the multiple capacitor chips 101. The capacitor buffer plays a vital intermediate regulating role.

[0086] In this embodiment, since the external track 200 needs to transmit electricity over long distances, the voltage values ​​in different sections and at different times may fluctuate greatly. The capacitor buffer can absorb the voltage fluctuations of the external track 200, so that multiple capacitor chips 101 can safely provide compensation for the external track 200 under any circumstances.

[0087] It can be concluded from the above that the present embodiment can protect the plurality of capacitor chips 101 from damage caused by voltage fluctuations, ensure that the plurality of capacitor chips 101 can be powered safely, and extend the service life.

[0088] In one embodiment of the present disclosure, the plurality of capacitor chips 101 are packaged by resin potting.

[0089] In this embodiment, in order to ensure that multiple capacitor chips 101 can achieve quick waterproof function, they can be encapsulated by resin potting to achieve isolation of each capacitor chip from the outside world. Among them, resin potting is a process of mechanically or manually pouring liquid epoxy resin compound into a device equipped with electronic components and circuits, and assimilating it into a thermally homogeneous polymer insulating material with excellent performance under normal temperature or heating conditions. This process is widely used in the field of electronic packaging to protect electronic components from the influence of the external environment and improve the reliability and durability of products.

[0090] It can be concluded from the above that the present embodiment can realize the waterproof sealing design of multiple capacitor chips 101, improve their durability, and better adapt to the railway environment.

[0091] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them.
