[0018] The following is a clear and complete description of the technical solutions in the embodiments of the utility model in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0019] like Figure 1 As shown, this embodiment provides a high-speed power supply boost centralized control cabinet. The high-speed power supply boost centralized control cabinet includes a cabinet 11, a transformer 12 is arranged in the cabinet 11, and an input port 13 and an output port 14 for accessing an external transmission line are arranged on the cabinet 11. Among them, the transformer 12 is a boost transformer.

[0020] Specifically, a battery module 15 is also provided in the cabinet 11. The low voltage side of the transformer 12 is connected to the input port 13, and the high voltage side of the transformer 12 is connected to the output port 14 to boost the current in the transmission line. More specifically, a first switch 101 is provided between the transformer 12 and the input port 13. When a power supply problem occurs in the cable of the front section of the highway power supply boosting centralized control cabinet, the first switch 101 can be opened to cut off the connection between the cable section and the subsequent line to ensure the safety of power distribution; at the same time, damage to the electrical equipment in the highway power supply boosting centralized control cabinet can be avoided. Further, the battery module 15 is connected to the input port 13 through the first switch 101, and a second switch 102 is provided between the first switch 101 and the battery module 15. When a problem occurs in the battery module 15, the external load, or other electrical equipment in the highway power supply boosting centralized control cabinet, the second switch 102 can be opened to cut off the connection between the battery module 15 and the transmission line to reduce the impact of the faulty equipment on the main line. At this time, the transmission line can still be transformed through the transformer 12 and supply power to the subsequent line.

[0021] Furthermore, a detection module 16 is also provided in the cabinet 11. The detection module 16 is connected to the input port 13, the battery module 15 and the external terminal. The detection module 16 can detect the input voltage of the input port 13 and the output voltage of the battery module 15, and transmit them to the external terminal. The first switch 101 and the second switch 102 are respectively connected to the external terminal for communication; when the input voltage of the input port 13 is abnormal, the detection module 16 outputs a first voltage alarm signal to the external terminal, and the external terminal controls the first switch 101 to open after receiving the first voltage alarm signal; when the output voltage of the battery module 15 is abnormal, the detection module 16 outputs a second voltage alarm signal to the external terminal, and the external terminal controls the second switch 102 to open after receiving the second voltage alarm signal.

[0022] Through the above settings, the highway power supply booster centralized control cabinet can timely detect power supply problems on the highway power supply and distribution line, and remotely control to cut off the connection between itself and the subsequent lines and the line to protect the electrical equipment in the cabinet 11 and on the main line, thereby improving the safety of highway power supply and distribution. When a power supply problem occurs to the equipment in the cabinet 11, the highway power supply booster centralized control cabinet can also remotely cut off the connection between the equipment and the power supply main line to avoid affecting the normal operation of other equipment on the main line.

[0023] like Figure 1 and Figure 2 As shown, the battery module 15 includes a conversion unit 151 and an energy storage unit 152. Among them, the conversion unit 151 is connected to the energy storage unit 152. The conversion unit 151 is also connected to the second switch 102 and the external load. Among them, the external load includes the highway ETC gantry system, monitoring equipment, lighting equipment, etc. When the second switch 102 is closed, the transmission line supplies power to the external load through the conversion unit 151, and charges the energy storage unit 152. The conversion unit 151 is used to convert the voltage of the input current into 1020V and transmit it to the external load; at the same time, a part of the input current is converted into direct current to charge the energy storage unit 152. When the second switch 102 is opened, the energy storage unit 152 supplies power to the external load through the conversion unit 151, and the power supply time of the energy storage unit 152 is greater than or equal to 2 hours to ensure the normal operation of the external load, thereby improving the reliability of the power supply of the highway power supply booster control cabinet.

[0024] like Figure 2 As shown, a current transformer 17 is provided between the conversion unit 151 and the second switch 102, and the current transformer 17 is used to reduce the input current of the transmission line to 5A to protect the battery module 15 and other electrical equipment in the cabinet 11. Furthermore, the current transformer 17 is connected to the detection module 16, and a third switch 103 is provided between the current transformer 17 and the conversion unit 151, and the third switch 103 is communicatively connected to the external terminal. The detection module 16 can detect the output current of the current transformer 17. When the output current of the current transformer 17 is abnormal, the detection module 16 outputs a current warning signal to the external terminal; after receiving the current warning signal, the external terminal controls the third switch 103 to open to protect the battery module 15, thereby improving the safety of the operation of the highway power supply booster control cabinet.

[0025] Furthermore, the current transformer 17 can also be connected to an external load through an external maintenance bypass of the battery module 15. Specifically, the current transformer 17 is connected to the external load through the fourth switch 104. Among them, a padlock 1041 is provided on the fourth switch 104 to ensure that the fourth switch 104 is in a normally open state. When the staff repairs the battery module 15, the padlock 1041 can be opened and the fourth switch 104 can be closed, and the third switch 103 can be opened at the same time.

The door magnetic switch 191 is connected to the monitoring module 18. When the door magnetic switch 191 is opened, the monitoring module 18 sends a door opening alarm signal to the external terminal, so that the staff can promptly discover abnormal conditions such as loss or damage of the equipment in the cabinet 11.

[0027] The highway power supply boost control cabinet also includes a battery detection module 21 and a battery monitoring host 22.

[0028] The highway power supply boost control cabinet also includes an air conditioner 23, which is connected to the monitoring module 18. The monitoring module 18 can monitor the temperature and humidity in the cabinet 11. When the temperature and humidity in the cabinet 11 are outside the operating temperature and humidity range, the monitoring module 18 outputs a temperature and humidity alarm signal to the external terminal. After receiving the temperature and humidity alarm signal, the external terminal controls the air conditioner 23 to adjust the temperature through the monitoring module 18. Among them, the operating temperature range of the highway power supply boost control cabinet is -20℃~60℃, and the operating humidity range is a humidity value less than 98%. Specifically, the air conditioner 23 is connected to the current transformer 17 through the fifth switch 105, so that the air conditioner 23 is powered by the transmission line. The fifth switch 105 is connected to the external terminal in communication. When the output current of the current transformer 17 is abnormal or the input current of the transmission line is abnormal, the external terminal can open the fifth switch 105 to protect the air conditioner 23.

The monitoring module 18 can monitor the water immersion degree in the cabinet 11. When the water immersion degree is higher than a preset threshold, the monitoring module 18 outputs a water immersion alarm signal to an external terminal. After receiving the water immersion alarm signal, the external terminal controls the water immersion device 24 through the monitoring module 18 to adjust and drain water, so as to prevent the electrical equipment in the cabinet 11 from short-circuiting due to water immersion.

[0030] The high-speed power supply boost control cabinet also includes a surge protection module 25, which is connected to the current transformer 17. Specifically, the surge protection module 25 includes a fuse 251 and a surge protector 252. Among them, the fuse 251 is connected to the current transformer 17, and the surge protector 252 is connected to the fuse 251 and grounded to perform surge protection on the electrical equipment in the line. More specifically, the surge protection module 25 can defend against 8 / 20us waveform lightning current, and the nominal discharge current of the surge protection module 25 is 20kA, and the maximum discharge current is 40kA.

[0031] In summary, the present application provides a highway power supply boosting control cabinet, which can timely detect power supply problems of transmission lines and cables and electrical equipment in the control cabinet, and isolate the fault point by remotely controlling the line on and off through an external terminal, thereby improving the safety and reliability of highway power supply and distribution.
