Description

Technical Field

[0001] The present invention relates to the technical field of intelligent power distribution, and in particular to a railway intelligent power distribution box and a railway intelligent power distribution management system. Background Art

[0002] With the rapid development of railways, the safety requirements for railway passenger transport, the increase in freight volume and users' expectations for the quality of power supply have continuously increased the requirements for the quality and reliability of low-voltage power supply equipment. Therefore, the effective and safe operation of low-voltage distribution equipment has become more important in railway transportation.

[0003] Railway low-voltage power distribution equipment often suffers from power loss, power phase loss, power cable failure, heavy load burnout switch, short circuit failure, etc., which can damage the power supply equipment. Since railway low-voltage power distribution equipment cannot be monitored in real time, when the operation and maintenance personnel arrive at the fault site to handle it after receiving the maintenance information, the fault has been delayed. In particular, for problems such as power outages in two signal power supplies at the station, no signal indication or red light bands in the section caused by distribution equipment failure, delayed processing will directly and seriously affect normal production and transportation. Therefore, the operating status of railway low-voltage power distribution equipment is related to whether the entire power supply network and even the entire transportation line can operate normally, and the detection and management of its operating parameters and status are particularly necessary.

[0004] Currently, the following two methods are usually used to monitor the power distribution facilities of high-speed passenger channels, conventional railways and freight dedicated lines:

[0005] One is that, for example, the station machinery room uses two power supplies to switch between the main and standby power supplies, and transmits the power supply status through wireless communication, so that the dispatching end can monitor online through the LAN platform software. The line section signal power supply uses a wireless network to monitor, which can control the switch by opening and closing. When it is known that the power distribution facilities have a fault, the fault information is uploaded to the dispatching end, and then the dispatching end sends instructions to the workshop or maintenance area for processing, or the operating personnel find the problem and feedback it to the workshop or work area for further processing. Therefore, for important places, the fault handling delay in the monitoring process is relatively long, affecting the normal power supply.

[0006] Another is that the power load switch needs to be opened and closed on site, and there is no remote monitoring function, so data such as voltage and current cannot be obtained in real time. When the power distribution facilities fail, the monitoring personnel cannot obtain the fault information in the first time. It is not until the fault affects the power equipment, the normal power consumption of the personnel is affected, or the driving results are affected that the power equipment is found to have failed. At this time, organizing the treatment or repair will undoubtedly cause serious adverse consequences. In addition, the location of the power equipment is generally far away from the work area. After receiving the fault maintenance notice, there will be unforeseen situations in organizing personnel, checking tools, and driving, which will further delay the handling of the accident.

[0007] It can be seen that the existing distribution box has a complex fault feedback process, which leads to a long delay in fault handling and the maintenance personnel are unable to obtain the fault information of the distribution box in the first time. Summary of the invention

[0021] The accompanying drawings are used to provide a further understanding of the embodiments of the present invention and constitute a part of the specification. Together with the following specific implementations, they are used to explain the embodiments of the present invention, but do not constitute a limitation on the embodiments of the present invention. In the accompanying drawings:

[0022] Figure 1is a schematic block diagram of a railway intelligent distribution box according to an exemplary embodiment;

[0023] Figure 2 It is a schematic block diagram of a cloud power distribution intelligent circuit breaker according to an exemplary embodiment. DETAILED DESCRIPTION

[0024] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0025] Figure 1 is a schematic block diagram of a railway intelligent distribution box according to an exemplary embodiment. Figure 1 As shown, the railway intelligent distribution box includes a box body (not shown) and a distribution device 1 and a cloud distribution intelligent circuit breaker 2 arranged in the box body. The cloud distribution intelligent circuit breaker 2 is connected to the distribution device 1 to obtain the operating status and / or fault information of the distribution device 1, and send the operating status and / or the fault information to a remote terminal.

[0026] For example, the power distribution equipment 1 can be regarded as a power supply line connected to the power consumption equipment, such as a 380V three-phase power supply line, which is connected to the power consumption equipment to provide the power consumption equipment with the required high-voltage power supply. The operating status in the embodiment of the present invention can include two types: one is the action status of each device in the power distribution equipment, such as the opening and closing status of the switch, etc., and the other is the operating status of each device in the power distribution equipment itself, such as the operating time, voltage and current of the device. Therefore, in the embodiment of the present invention, the cloud distribution intelligent circuit breaker 2 can be connected to the power distribution equipment 1, for example, connected to the power supply line, to monitor the operating status of each power supply line. For the cloud distribution intelligent circuit breaker, on the one hand, it collects the operating status and fault information of the distribution equipment in real time, and on the other hand, it communicates with the remote terminal and sends the collected operating status and fault information of the distribution equipment to the remote terminal, so that the remote terminal can obtain the real-time situation and fault information of the distribution equipment in time, and then perform fault repair in time. For example, the remote terminal can implement remote opening and closing control of the cloud distribution intelligent circuit breaker, and when the line is overloaded or the fault reaches the set value, the cloud distribution intelligent circuit breaker can automatically trip in time to cut off the faulty load line.

[0027] In the embodiment of the present invention, information can be collected in real time through the cloud distribution intelligent circuit breaker, so that the terminal system located remotely can obtain the operating status and fault information of the distribution equipment in real time, which is conducive to remote monitoring and efficient management, can reduce the labor intensity of operation and maintenance personnel, and effectively shorten the power outage time. Compared with the traditional distribution box, the railway intelligent distribution box provided by the implementation of the present invention does not need to add auxiliary secondary equipment and wiring such as mutual inductors, relays, power meters, microcomputer protectors, etc., and can complete the monitoring and protection of the incoming and outgoing line circuits of the distribution equipment. The four shaking functions break the operating mode of conventional switches and protection devices, realize the organic integration and centralized unification of switches and protection, reduce the internal wiring of the distribution box, avoid interference and danger caused by too many line crossings, and effectively reduce costs.

[0028] In a preferred embodiment, if Figure 2 As shown, the cloud distribution intelligent circuit breaker 2 includes: a collection device 21, which is electrically connected to the distribution equipment and is used to collect status signals and operating parameters reflecting the operating status of the distribution equipment; a main control device 22, which is electrically connected to the collection device 21, and is used to process and analyze the collected status signals and operating parameters to generate status information and / or fault information of the distribution equipment; and a control instruction for controlling the distribution equipment generated based on the fault information or the remote instruction of the remote terminal; a communication device 23, which is connected to the main control device 22, and is used to obtain and transmit the status information and / or fault information generated by the main control device 22 to the remote terminal, and is used to receive the remote instruction sent by the remote terminal; a switch device 24, which is electrically connected to the main control device 22 and the distribution equipment, and is used to control the on and off of the distribution equipment based on the control instruction sent by the main control device 22.

[0029] For example, the acquisition device 21 may include a signal collector for collecting status signals and a sensor for collecting operating parameters. For example, the operating parameters may include the current and voltage of the power distribution equipment, and the sensors for collecting current and voltage may include current sensors and voltage sensors. Specifically, the current sensor and the voltage sensor are connected to the incoming and outgoing line circuits of the power distribution equipment to monitor the real-time current signal and voltage signal of the power distribution equipment in real time. Considering that the railway distribution box needs to perform rectification, filtering and other purification treatments on the power supply voltage of the connected contact network, in order to be able to collect more accurate voltage and current signals, the acquisition device 21 of the embodiment of the present invention can be connected to the incoming and outgoing line circuits between the purification device for the power supply voltage purification and the electrical equipment. The embodiment of the present invention is not limited to the above-mentioned acquisition device, and those skilled in the art can flexibly adopt the corresponding acquisition device based on the actual acquisition needs and the parameters and signals to be collected.

[0030] The main control device 22 includes an advanced ARM chip, which can process and calculate the state signals and operating parameters collected by the acquisition device 21, and then calculate the power operation parameters of the power distribution equipment such as current, voltage, power, power consumption, load imbalance and reactive power demand. At the same time, the main control device 22 can also analyze the acquired power operation parameters to determine whether the power distribution equipment has a fault, so as to obtain the corresponding fault information. The main control device 22 is electrically connected to the communication device 23, and sends the generated state information and / or fault information to the communication device 23.

[0031] The communication device 23 may include a 5G communication module, an Ethernet communication module, a fiber optic communication module and a LORA communication module, and adopt a corresponding communication protocol to communicate with the remote terminal, and transmit status information and / or fault information to the remote terminal, so that the remote terminal can promptly obtain the status information and / or fault information of the power distribution equipment, and obtain the remote terminal's remote instructions for the power distribution equipment, wherein the remote instructions may include control information used by the remote terminal to control the actual operation of the power distribution equipment or configuration information used to change the corresponding configuration parameters of the power distribution equipment.

[0032] The switch device 24 may include a driving mechanism and an actuator. The driving mechanism is electrically connected to the main control device 22, and can respond to the control instructions received from the main control device 22, thereby driving the actuator to perform actions. The actions here mainly refer to opening and closing actions. Regarding the control instructions of the main control device 22, there may be two situations. One is the control instructions generated by the main control device 22 based on the fault information generated by it. Specifically, when the main control device 22 analyzes the power operation parameters and determines that the current power distribution equipment is abnormal and fails, the main control device 22 generates corresponding control instructions to control the switch device 24 to perform an opening operation to disconnect the connection between the power distribution equipment and the power-consuming equipment, so as to avoid the safety impact of the failure of the power distribution equipment on the power-consuming equipment. The other is the control instruction generated by the main control device 22 based on the demand information of the remote terminal. Specifically, when the remote terminal needs to power off the power distribution equipment, the main control device 22 generates corresponding control instructions based on the demand information of the power-off demand, and then controls the switch device 24 to perform an opening operation on the power distribution equipment to meet the control requirements of the remote terminal for the power distribution equipment.

[0033] In addition, the cloud power distribution intelligent circuit breaker of the present application may also include a manually operated circuit breaking mechanism, which enables operators to perform circuit breaking operations on-site.

[0034] It can be seen from the embodiments of the present invention that the cloud power distribution intelligent circuit breaker automatically disconnects the faulty power distribution equipment after a fault occurs in the power distribution equipment, so that the remote terminal can quickly analyze the cause of the fault according to the fault information and quickly handle it, thus shortening the fault time; the remote terminal can remotely control the power distribution equipment to ensure the personal safety of the switching operators, especially to solve the personal safety risks of operating equipment in severe weather such as thunderstorms.

[0035] In a preferred embodiment, the railway intelligent distribution box further comprises: an environment detection device, which is placed in the box and is used to detect environmental information inside the box.

[0036] For example, the distribution equipment will be affected by the internal environment of the box during operation. For example, when the temperature inside the box is too high, it will cause the operating temperature of the distribution equipment to be too high, thereby affecting the power supply of the distribution equipment to the power-consuming equipment. For another example, when the humidity inside the box is too high, it is easy for the distribution equipment to short-circuit, etc., thereby affecting the operation safety of the distribution equipment. Therefore, the railway pan-intelligent distribution box of the embodiment of the present invention is provided with an environmental detection device to detect environmental changes in the distribution box. And the environmental detection device is connected to the cloud distribution network device in communication. For example, the environmental detection device can be connected to the cloud distribution intelligent circuit breaker based on wireless WIFI, Bluetooth, Zigbee and other communication protocols, and the environmental information obtained is sent to the remote terminal through the cloud distribution intelligent circuit breaker, or the environmental detection device can communicate directly with the remote terminal, so that the remote terminal can obtain the on-site environmental conditions in the distribution box in real time, and then the remote terminal can make a timely prediction based on the environmental information, effectively avoid the occurrence of faults, and ensure the operation safety of the distribution equipment.

[0037] In addition, the environment inside the box will also have a certain impact on the operating life of the distribution equipment. Therefore, by setting up an environmental detection device to obtain and analyze the environmental data inside the box in real time, it is possible to predict in advance the life loss of the distribution equipment during environmental changes, and then formulate a corresponding distribution equipment maintenance plan based on its life loss to avoid safety accidents caused by the aging of the distribution equipment itself.

[0038] The railway intelligent distribution box of the embodiment of the present invention can obtain the operating environment of the distribution equipment in real time by setting up an environmental detection device, so that the terminal system located remotely can judge the fault of the intelligent distribution box based on the environmental information. At the same time, the railway intelligent distribution box can effectively control the internal environment of the box based on real-time environmental information to ensure the normal operating environment of the distribution equipment.

[0039] In a preferred embodiment, the environment detection device includes: a smoke sensing device for sensing smoke information in the box; and a temperature and humidity control device for collecting and controlling temperature and humidity changes in the box.

[0040] For example, the smoke sensing device implements fire prevention inside the box by monitoring the concentration of smoke. Specifically, when the smoke concentration inside the box detected by the smoke sensing device exceeds the threshold, an alarm prompt can be issued according to the situation of exceeding the threshold, and the abnormal concentration information is sent to the cloud platform via the cloud power distribution network device, so that each terminal system connected to the cloud platform can be informed in time. The temperature and humidity control device may include a temperature sensor, a humidity sensor and an adjustment control unit. Specifically, the temperature sensor can be fixed inside the box to collect the temperature inside the entire box space, and can also be connected to the power distribution equipment to collect the temperature changes of the power distribution equipment itself. The humidity sensor is used to collect humidity changes in the internal space of the box. The adjustment control unit can automatically adjust the temperature and humidity inside the box according to the temperature and humidity conditions collected by the temperature sensor and the humidity sensor, so as to ensure that the power distribution equipment in the box operates in a suitable temperature and humidity environment.

[0041] In addition, the embodiments of the present invention are not limited to the above-mentioned detection devices. Those skilled in the art can also set corresponding detection devices according to actual environmental detection needs to perform comprehensive and effective detection of the environment inside the box.

[0042] In a preferred embodiment, the railway intelligent distribution box also includes a video monitoring device for collecting video images of the distribution equipment in the box.

[0043] For example, the video monitoring device may include a high-definition digital network camera, a network hard disk recorder, etc. The video monitoring device can capture the video image of the power distribution equipment in real time and send the video image to the remote terminal, so that the remote terminal can further determine the fault condition through the video image of the power distribution equipment based on the acquired fault information, such as determining the specific location of the fault, the severity of the fault, etc., so that the terminal system can adopt an accurate and reliable maintenance strategy to repair the power distribution equipment.

[0044] In the embodiment of the present invention, by setting up a video monitoring device, it is possible to assist in determining the fault condition, so that maintenance personnel can use a more reliable maintenance method to perform maintenance and handle the fault in a timely and flexible manner. In addition, the video monitoring device can monitor the operating behavior of the operator in real time to avoid safety accidents caused by illegal operations of the operator.

[0045] In a preferred embodiment, the railway intelligent distribution box further comprises an emergency power supply device for providing electric energy for the operation of various devices in the railway intelligent distribution box when a working power supply fails.

[0046] For example, in an embodiment of the present invention, the power distribution equipment usually uses a working power supply to power the power distribution equipment, wherein the working power supply uses an AC220V power supply. When the working power supply fails to supply power, it will cause the power distribution equipment to supply power to the power-consuming equipment abnormally, affecting the use of the power-consuming equipment. Therefore, in an embodiment of the present invention, a backup power supply is provided to supply power to the power distribution equipment when the working power supply fails and fails to supply power. Specifically, the backup power supply can be connected to the cloud power distribution intelligent circuit breaker. Since the cloud power distribution intelligent circuit breaker can obtain the operating status of the power distribution equipment in real time, when the cloud power distribution intelligent circuit breaker learns that the power distribution equipment is operating abnormally and determines that the working power supply has failed, it sends a startup command to the backup power supply, so that the backup power supply starts and continues to supply power to the power distribution equipment.

[0047] More preferably, the backup power supply includes a UPS power supply and a wind-solar complementary power supply.

[0048] For example, a UPS power supply includes a battery, which can meet the power demand of the distribution box by storing electrical energy. When the working power fails, it can supply power to the distribution equipment nearby in time. A wind-solar hybrid power supply can obtain electrical energy in the form of wind or solar energy. When the internal power of the UPS power supply is insufficient or the UPS power supply itself is damaged, the wind-solar hybrid power supply can also supply power to the distribution equipment based on wind or solar energy.

[0049] In a preferred embodiment, the railway intelligent distribution box also includes: a display device, which is arranged on the box body and connected to the cloud distribution intelligent circuit breaker, and is used to display the operating status and / or fault information of the distribution equipment.

[0050] For example, the display device may be an LED display screen, which may be embedded on the surface of the box to display the current operating parameters of the power distribution equipment, operating time, online or offline status of the power distribution equipment, time-sharing electricity or power consumption analysis, etc. It may also display fault codes and warning icons representing fault information, so that on-site operators can promptly learn about the status of the railway intelligent distribution box.

[0051] Listed below are the performance parameters of a railway intelligent distribution box, from which it can be seen that the railway intelligent distribution box realizes the remote Internet of Things function by adopting cloud distribution intelligent circuit breakers and cloud distribution network devices, making the overall structure of the railway intelligent distribution box compact, flexible in application, and more accurate in monitoring.
