Description

Technical Field

[0001] This utility model relates to the field of monitoring system technology, specifically to a comprehensive monitoring system for intelligent substations in tunnels. Background Technology

[0002] The country boasts a long highway network with numerous tunnels, most of which are located in remote areas, resulting in high maintenance costs. Due to the complexity of the electromechanical systems in highway tunnels, including multiple subsystems such as lighting, ventilation, monitoring, fire protection, traffic guidance, environmental monitoring, fire alarms, and public address systems, continuous monitoring and maintenance are required 24 / 7. Tunnel substations provide a stable power supply for the tunnel's monitoring, lighting, ventilation, and traffic guidance equipment. This process involves high electricity consumption and costs, necessitating the installation of numerous power distribution facilities and other critical electromechanical equipment, along with metering meters for billing purposes.

[0003] The use and maintenance of existing tunnel substations have the following shortcomings:

[0004] 1) A standard electricity meter is used, requiring manual meter readings periodically;

[0005] 2) No power monitoring system was installed, and there was a lack of means to monitor and analyze the power supply and distribution operation status, thus failing to detect in a timely manner the functional loss of the tunnel electromechanical system caused by power supply and distribution abnormalities;

[0006] 3) The power distribution room lacks systematic automatic monitoring methods. When problems such as system abnormalities, power outages, and equipment failures occur, they cannot be automatically detected and alarmed, posing safety hazards.

[0007] 4) The lack of monitoring of the generator makes it impossible to detect problems such as insufficient generator oil or generator malfunctions in a timely manner. This leads to the inability to ensure the subsequent power supply and operation of the tunnel electromechanical system after power outages or other events, posing a significant risk.

[0008] 5) Lack of online monitoring of UPS, lack of monitoring and understanding of UPS backup time, battery status and operation status, which makes it impossible to ensure stable operation of UPS and timely detection of UPS failure.

[0009] 6) The power distribution room lacks automatic access control, resulting in a lack of supervision and traceability regarding the operation and maintenance of the equipment room and personnel entry and exit;

[0010] 7) There is no environmental condition monitoring in the power distribution room, so it is impossible to effectively monitor abnormal conditions such as water immersion, fire, and excessive humidity in the power distribution room.

[0011] 8) Manual inspection of tunnels is difficult to detect abnormalities in a timely manner, posing safety hazards. Utility Model Content

The input terminal of the uninterruptible power supply is connected to the automatic transfer switch.

[0034] The tunnel is equipped with fans, water pumps, roller shutters, lighting fixtures, lane indicator lights, and cameras. The fans, water pumps, roller shutters, lighting fixtures, lane indicator lights, and cameras are connected to the outgoing terminals of a low-voltage switchgear. Specifically, the lighting fixtures, lane indicator lights, and cameras are connected to the low-voltage switchgear, which is equipped with an uninterruptible power supply (UPS). Each outgoing terminal of the low-voltage switchgear is connected to a small intelligent three-phase electricity meter. Figure 1 (A3). The smart meter, operation status detector, data acquisition unit, and small smart three-phase meter are all connected to the control host via data cables.

[0035] Specifically, an access control device is installed at the entrance of the substation, and the access control device is connected to the control host via a data cable.

[0036] Specifically, cameras are installed inside the substation. Figure 1 (C1) The camera and the control host are connected via a data cable.

[0037] Specifically, the substation has a distribution room, the low-voltage outgoing line cabinet is located in the distribution room, and the distribution room is equipped with an environmental monitoring instrument. Figure 1 (B1) and immersion detector ( Figure 1 In section B2), both the environmental monitoring instrument and the immersion detector are connected to the control host via data cables.

[0038] See Figures 2 to 4 An uninterruptible power supply (UPS) consists of four vertical bars (11), several longitudinal bars (12), and several horizontal bars (13). The two ends of the longitudinal bars (12) are fixed to the two front and rear vertical bars (11), and the two ends of the horizontal bars (13) are fixed to the two sides of the longitudinal bars (12). See... Figure 4Four horizontal bars 13 are connected between the two vertical bars 12 on the bottom side. The four horizontal bars 13 are divided into two groups, with gaps between the two horizontal bars 13 in the same group. Several lower cooling fans 14 are provided on the upper side of the two horizontal bars 13 in the same group. The two sides of the lower cooling fans 14 are fixed to the top side of the two horizontal bars 13 respectively.

[0039] Specifically, the uninterruptible power supply (UPS) housing has a bottom cover 15 with an air vent 151, and a gap is left between the lower cooling fan 14 and the bottom cover 15. The UPS housing has support feet 16 at the four corners of the bottom.

[0040] Specifically, the top cover 17 of the uninterruptible power supply housing is provided with several air outlets 171, which are arranged in a rectangular pattern, and an upper cooling fan 18 is fixed to the bottom wall of each air outlet 171.

[0041] Specifically, a capacitor plate 19 is connected to the rear side of the two horizontal bars 13 distributed along the top and bottom, and a number of capacitors 191 are provided on the rear side of the capacitor plate 19. A heat sink 2 is fixed to the front side of the two horizontal bars 13.

[0042] The working principle of this utility model is as follows:

[0043] After the mains power is stepped down by a transformer, it is distributed to various low-voltage outgoing switchgear. The outgoing lines from these switchgear supply power to the various electrical appliances in the tunnel. Smart meters are connected to the transformer's outgoing terminals. Figure 1 (A1) By collecting data such as power supply voltage, current, power, and energy through smart meters, the power consumption of substation equipment can be collected in real time. By configuring the corresponding electricity price, the power consumption and electricity cost of the tunnel substation can be monitored in real time.

[0044] By installing small intelligent three-phase meters in each power distribution output circuit of the low-voltage outgoing cabinet ( Figure 1 The A3 system can monitor and analyze the power distribution, power consumption, and trends of various power distribution circuits and equipment in the tunnel.

[0045] The generator is equipped with an operating status monitoring device ( Figure 1 The A2) operation status detector monitors and analyzes the generator's real-time operating status and fuel tank status, and can obtain information such as fuel level increase / decrease and average fuel consumption. When the fuel level in the tank is low, it promptly reminds maintenance personnel to replenish the fuel to prevent fuel shortage risks, and predicts and analyzes the generator's power generation time and provides response reminders.

[0046] The uninterruptible power supply (UPS) is equipped with a data acquisition unit ( Figure 1(A4) The data acquisition unit collects various status data of the uninterruptible power supply (UPS) in real time and provides real-time alerts when the UPS malfunctions, preventing safety hazards caused by the UPS failing to work properly when the mains power is interrupted.

[0047] The system installs electronic access control at the main entrances and exits of the power distribution room and generator room to effectively monitor personnel in these areas. This is achieved by installing one camera in each of the power distribution room, generator room, and backup power room. Figure 1 (C1) to achieve online monitoring of the substation interior.

[0048] The system is equipped with environmental monitoring instruments in the power distribution room, generator room, and high-voltage room. Figure 1 The B1 module enables online monitoring and data reporting of temperature, humidity, and smoke levels inside the substation.

[0049] The system is equipped with immersion detectors in the power distribution room, generator room, and high-voltage room. Figure 1 (B2) enables online monitoring and data reporting of water immersion and leakage inside the substation.

[0050] When the mains power fails, the uninterruptible power supply (UPS) can still supply power to the low-voltage outgoing cabinet it is connected to, enabling the lighting circuit, lane indicator circuit, and camera circuit led out from the low-voltage outgoing cabinet to continue to operate normally, thus maintaining the basic functions of the tunnel. Therefore, daily charging of the UPS is crucial, as is cooling it.

[0051] To achieve effective cooling of the uninterruptible power supply (UPS), a capacitor bank 19 is located in the lower part of the UPS's internal cavity. A heat sink 2 is located on the front side of the capacitor bank 19, which promptly absorbs heat from the capacitor bank 19, maintaining it at a low temperature. Multiple lower cooling fans 14 are located on the lower side of the capacitor bank 19. The bottom cover 15 of the UPS housing has vents 151, with gaps between the lower cooling fans 14 and the bottom cover 15. Support feet 16 are located at the four corners of the bottom of the UPS housing, creating gaps between the bottom cover 15 and the ground, allowing the lower cooling fans 14 to effectively extract hot air from the UPS's internal cavity.

[0052] The top cover 17 of the uninterruptible power supply (UPS) housing has several air outlets 171, which are arranged in a rectangular pattern. Each air outlet 171 has an upper cooling fan 18 fixed to its bottom wall. The multiple cooling fans 18 draw out the hot air from the UPS interior.

[0053] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
