Description
Technical Field
[0001] The utility model relates to the technical field of tunnel construction, in particular to a dual-power intelligent networking power supply system. Background Art
[0002] During tunnel construction, water may sometimes gush out of the tunnel, which seriously affects the construction safety of the tunnel. In addition, tunnels often have a certain slope, so a pumping station is usually required in the tunnel to actively drain the tunnel. Existing pumping stations are generally powered by AC power.
[0003] However, for tunnels in certain high-altitude areas, the amount of water inflow in the tunnel is very huge. For example, a tunnel with a total length of 881 meters is continuously downhill along the line, with a maximum height difference of 40 meters. The maximum water inflow in the inclined shaft section reaches 50,000 m³ / d; the main tunnel section is continuously uphill, with a maximum height difference of 128 meters, and the maximum water inflow reaches 75,000 m³ / d. The intersection of the inclined shaft and the main tunnel is the lowest point of the line, and the water inflow gathers here, reaching 125,000 m³ / d. Therefore, its reverse slope drainage construction is extremely risky and highly dependent on electricity. Once the city power outage occurs and the power supply cannot be quickly restored, it is very likely to cause tunnel flooding accidents. Therefore, there is an urgent need to develop a new power supply system that can provide uninterrupted power supply to the tunnel pump station. Utility Model Content

[0035] Example 1
[0036] like Figures 1 to 2 As shown, a dual-power intelligent networking power supply system includes a ring network cabinet 1, a first power supply line 101, a second power supply line 102, a power generation module 4, a control module 5 and an output line 103; the ring network cabinet 1 includes an input end and an output end; one end of the first power supply line 101 is electrically connected to the input end, and the other end of the first power supply line 101 is electrically connected to the mains 2, and the first power supply line 101 is provided with an output detection module 3; the output detection module 3 includes a current sensor and / or a voltage sensor; one end of the second power supply line 102 is electrically connected to the input end, and the other end of the second power supply line 102 is electrically connected to the power generation module 4; the power generation module 4 includes at least two generators 41 connected in parallel with each other; the control module 5 is communicatively connected to the output detection module 3 and the power generation module 4, the control module 5 can receive the reading of the output detection module 3, and control the starting number of generators 41 in the power generation module 4 and / or the output power of the generator 41 according to the reading of the output detection module 3; one end of the output line 103 is electrically connected to the output end, and the other end of the output line 103 is used to supply power to the tunnel.
[0037] It should be noted that although Figure 1 and Figure 2 The direction of the symbol used to represent the communication connection is only for illustration, but in fact the communication connection can be bidirectional. For example, the control module 5 can send control signals to the power generation module 4 and receive feedback signals from the power generation module 4.
[0038] In an optional embodiment, the generator 41 further includes a parallel controller 411, which includes at least one of a voltage regulation module (also known as an AVR or voltage regulator), a frequency regulation module, a phase regulation module, and a speed regulation module (also known as a GOV). The parallel controllers 411 of each generator 41 are interconnected, enabling the parallel controllers 411 to synchronize the operating states of each generator 41, which include at least one of voltage, frequency, and phase. This embodiment can prevent the operating states of each generator 41 from being out of sync, causing circulating current or equipment abnormalities, thereby ensuring that each generator 41 can safely and smoothly transition to parallel operation. The speed regulation module facilitates the allocation of different speeds by the power generation module 4 to each generator 41 based on actual power demand, thereby achieving on-demand load distribution. The voltage regulation module, frequency regulation module, phase regulation module, and speed regulation module can all directly utilize existing products or existing circuit designs.
[0039] In an optional embodiment, the generator 41 also includes a diagnostic module, which includes at least one of a speed sensor, a voltage sensor, a current sensor, a temperature sensor and a vibration sensor; the control module 5 is communicatively connected to the diagnostic module, and the control module 5 can determine the operating status of the corresponding generator 41 based on the detection data of the diagnostic module. When the detection data of the diagnostic module exceeds the set safety range, for example, the speed exceeds the maximum speed given by the manufacturer, or the temperature exceeds the maximum temperature given by the manufacturer, the control module 5 determines that the generator 41 is faulty and shuts down the faulty generator 41 by, for example, cutting off the fuel supply.
[0040] In an optional embodiment, the ring network cabinet 1 also includes a display module, which is communicatively connected to the diagnostic module and can display the detection data of the diagnostic module; the display module can adopt existing products, including but not limited to pointer dials, digital tubes, LED screens or OLED screens; the display module can also be integrated with a sound alarm system or an optical alarm system, so that when an abnormality occurs in the detection data, the display module can directly remind the staff to take refuge or come for inspection.
[0041] In an optional embodiment, a transformer 6 is further provided between the mains power 2 and the output line 103, and / or a transformer 6 is further provided between the power generation module 4 and the output line 103, so that the voltage of the mains power 2 and / or the generator 41 can be converted into the required voltage, for example, the 220V voltage of the mains power 2 can be increased to 10KV, or the 400V voltage output by the generator 41 can be increased to 10KV.
[0042] In the above embodiment, the specific number and position of the transformer 6 are determined according to whether the output of the mains 2 and the generator 41 meet the requirements. For example, if only the voltage of the mains 2 does not meet the requirements, a transformer 6 can be set between the first power supply line 101 and the ring main unit 1; if only the voltage of the generator 41 does not meet the requirements, a transformer 6 can be set between the generator 41 and the ring main unit 1; if both the voltages of the mains 2 and the generator 41 do not meet the requirements, Figure 1 As shown, a transformer 6 is arranged in front of the ring main unit 1, and the first power supply line 101 and the second power supply line 102 are both connected in parallel to the transformer 6, and the transformer 6 is then electrically connected to the input end of the ring main unit 1, so that one transformer 6 can take care of the voltage transformation of the first power supply line 101 and the second power supply line 102 at the same time, thereby saving the hardware cost of the transformer 6.
[0043] In an optional embodiment, the ring main unit 1 includes a heating module; the heating module enables the ring main unit 1 to withstand low temperatures, and the heating module can adopt existing products, including but not limited to resistance wire heaters, ceramic heaters or quartz tube heaters.
[0044] In an optional embodiment, the ring main unit 1 includes a dehumidification module, which enables the ring main unit 1 to withstand a humid environment. The dehumidification module can adopt existing products, including but not limited to condensing dehumidifiers, rotary dehumidifiers or semiconductor dehumidifiers.
[0045] In an optional embodiment, the ring network cabinet 1 includes an uninterruptible power supply module; the uninterruptible power supply module is also called a UPS module, which can provide the ring network cabinet 1 with the power required for basic operation after the mains power 2 is cut off and before the generator 41 is started, to prevent the ring network cabinet 1 from being unable to switch normally between the first power supply line 101 and the second power supply line 102 due to a complete power outage.
[0046] In an optional embodiment, an electrical interlock and / or mechanical interlock is provided between the first power supply line 101 and the second power supply line 102 to prevent the risk of electric shock caused by accidental touch by the staff; the specific design of the electrical interlock and the mechanical interlock can refer to existing specifications and use existing products. For example, normally closed auxiliary contacts can be provided on the contactors of the first power supply line 101 and the second power supply line 102, and the normally closed auxiliary contacts of the first power supply line 101 and the second power supply line 102 are respectively connected to the second power supply line 102 and the first power supply line 101, so that when the first power supply line 101 is connected, the auxiliary contacts of the second power supply line 102 are disconnected and no power is supplied. On the contrary, when the second power supply line 102 is connected, the auxiliary contact of the first power supply line 101 is disconnected and no power is supplied, thereby achieving electrical interlocking of the first power supply line 101 and the second power supply line 102; or a mechanical interlocking device is provided between the operating handles of the first power supply line 101 and the second power supply line 102. When the operating handle of the first power supply line 101 is connected, the mechanical interlocking device will jam the operating handle of the second power supply line 102. On the contrary, when the operating handle of the second power supply line 102 is connected, the mechanical interlocking device will jam the operating handle of the first power supply line 101, thereby achieving mechanical interlocking of the first power supply line 101 and the second power supply line 102.
[0047] In an optional embodiment, a feeder protection module is provided on at least one of the first power supply line 101, the second power supply line 102 and the output line 103, so as to automatically cut off the power supply protection device when the first power supply line 101, the second power supply line 102 and the output line 103 are damaged; the feeder protection module can refer to the existing circuit design and use existing products. Taking the first power supply line 101 as an example, an air circuit breaker with overload protection or an existing feeder protection relay can be set in the first power supply line 101.
[0048] In an optional embodiment, the generator 41 includes a diesel generator, which can ensure the reliable operation and long-term power generation of the generator 41, and can adapt to the harsh environment of high temperature, high humidity and high altitude, and is particularly suitable for the construction of high-altitude tunnels.
[0049] In an optional implementation manner, the current sensor may be an existing product, and its specific form includes but is not limited to a current transformer, a voltage transformer, an ammeter or a Hall current sensor.
[0050] In the above embodiment, the output detection module 3 includes a voltage transformer, which can detect whether the mains power 2 is out of power by detecting the voltage in the first power supply line 101 .
[0051] In an optional embodiment, a power detection module is provided in the output line 103, and the power detection module includes a current sensor and / or a voltage sensor. The power detection module is used to detect the total power of electrical appliances in the tunnel; the power detection module is communicatively connected to the control module 5, so that the control module 5 can automatically change the starting number of the generator 41 and / or the output power of the generator 41 according to the total power of the electrical appliances in the tunnel, thereby further improving the degree of automation of this embodiment.
[0052] In an optional embodiment, the communication connection includes but is not limited to a communication line connection or a wireless connection.
[0053] like Figure 3 As shown, it is a more specific electrical wiring diagram of a dual-power intelligent networking power supply system of this embodiment (only a part of the electrical connections are shown, so the control module 5 and the output detection module 3 are not shown); it can be seen that the mains power 2 is electrically connected to the high-voltage busbar 12 of the ring network cabinet 1 through the first power supply line 101, and then electrically connected to the tunnel transformer 6 through the high-voltage busbar 12, so that power can be supplied to the tunnel.
[0054] The power generation module 4 includes three generators 41, which are connected to each other via MSC communication so that the parallel controller 411 can synchronize the operating status of each generator 41. The three generators 41 are each equipped with an independent switch to switch the number of generators 41 connected to the grid. The three generators 41 are all electrically connected to the low-voltage busbar 11 of the ring main unit 1, and then electrically connected to the high-voltage busbar 12 through the transformer 6 and the second power supply line 102, so as to supply power to the tunnel and ensure that the voltage output by the generator 41 can meet the electricity demand of the tunnel.
[0055] And as Figure 3 As shown, the contacts of the first power supply line 101 and the second power supply line 102 are interlocked to prevent the first power supply line 101 and the second power supply line 102 from being accidentally connected at the same time.
[0056] A low-voltage side feeder 7 is also connected to one side of the ring main unit 1 so as to automatically cut off the power supply to protect the equipment when the line is damaged.
[0057] like Figure 4As shown, it is a more specific electrical wiring diagram of another dual-power intelligent networking power supply system of this embodiment (only a part of the electrical connections are shown, so the control module 5 and the output detection module 3 are not shown); it can be seen that the mains 2 is electrically connected to the input end of the ring network cabinet 1 through the first power supply line 101, and the power generation module 4 is electrically connected to the other input end of the ring network cabinet 1 through the second power supply line 102, and a switching switch is provided in the ring network cabinet 1 to enable it to switch between the two input ends (that is, switch between the first power supply line 101 and the second power supply line 102); the ring network cabinet 1; the output end of the ring network cabinet 1 is connected to the cable branch box through the output line 103, and then transformed by the transformer 6 for use in the tunnel power supply.
[0058] The operating principle of this embodiment is:
[0059] When the mains power 2 is supplying power normally, the output detection module can detect normal input (for example, 220V power input). At this time, the control module 5 does not send a start signal to any generator 41. The ring main unit 1 only receives the mains power 2 through the first power supply line 101 and supplies power to the equipment in the tunnel, such as the pump station and lighting equipment, through the output line 103.
[0060] When a power outage occurs in the mains 2, the output detection module can detect that there is no output in the first power supply line 101; at this time, the control module 5 sends a start signal to the corresponding number of generators 41 according to the actual power demand. The generator 41 generates electricity and inputs the electricity into the ring network cabinet 1 through the second power supply line 102, and then supplies power to the equipment in the tunnel, such as the pump station and lighting equipment, through the output line 103.
[0061] When the mains power 2 is restored, the output detection module can re-detect the normal input (for example, 220V power input). At this time, the control module 5 sends a shutdown signal to the generator 41, and the second power supply line 102 stops outputting power to the ring network cabinet 1, so that the ring network cabinet 1 switches back to the working mode of receiving the mains power 2 through the first power supply line 101 and supplying power to the equipment in the tunnel through the output line 103.
[0062] When a parallel controller 411 is provided on the motor, after the motor is started, the parallel controller 411 will first ensure the synchronization of the operating status of each motor, and then each generator 41 will be electrically connected to the ring network cabinet 1 one by one, so as to ensure that each generator 41 can safely and smoothly transition to the parallel operation state and reduce the impact of the generator 41 grid connection on the power grid; the judgment criteria for the synchronization of the operating status are: the frequency difference is less than 0.5Hz, the voltage difference is less than 10%, and the phase difference is less than 20°; and the speed of each motor may be adjusted separately according to the power demand, so it can not be used as the basis for judging whether the operating status is synchronized.
[0063] When the power demand of the electrical appliances in the tunnel changes, the control module 5 can match the corresponding power demand by changing the number of generators 41 started, for example, when the power demand increases, the number of generators 41 started is increased, and when the power demand decreases, the number of generators 41 started is reduced; or the speed of each generator 41 is adjusted, for example, when the power demand increases, the average speed of the generator 41 is increased, and when the power demand decreases, the average speed of the generator 41 is reduced; it should be noted that when a parallel controller 411 is provided on the motor, when adjusting the speed of each generator 41, the speed of each generator 41 can also be adjusted separately according to the load condition of each generator 41 through the speed adjustment module. For example, when a generator 41 is overloaded, the speed of the generator 41 can be reduced and the speeds of the remaining generators 41 can be increased, so as to avoid a generator 41 being overloaded or overloaded, thereby maintaining load balance.
[0064] After testing, this embodiment can quickly restore power supply within five minutes after the mains power 2 is cut off, thereby effectively preventing the occurrence of tunnel flooding accidents.
[0065] The above content is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
