Description

Technical Field

[0001] This invention relates to the field of low-voltage power distribution technology, specifically to a low-voltage complete power distribution equipment with remote intelligent monitoring function. Background Technology

[0002] A low-voltage power distribution system consists of a power distribution substation, high-voltage power distribution lines, power distribution transformers, low-voltage power distribution lines, and corresponding control and protection equipment.

[0003] The power supply of a low-voltage power distribution system is generally obtained by the power grid or substation through transformers, which convert the high-voltage power grid into low-voltage power and enter the bus of the low-voltage power distribution system. The power in the low-voltage power distribution system is distributed to each substation through low-voltage cables or conductors, and then finally distributed through distribution cabinets to ensure that each end user receives the correct power supply.

[0004] Each distribution cabinet in a low-voltage power distribution system needs to be equipped with corresponding control and protection devices, such as switches, circuit breakers, and fuses, to control and protect the circuit and prevent electrical accidents. Low-voltage distribution cabinets have multiple protection functions, such as overload protection, short-circuit protection, and undervoltage protection. When a circuit experiences an overload, short circuit, or undervoltage fault, the corresponding protection device will activate and quickly disconnect the circuit to protect the safety of equipment and personnel.

[0005] Existing low-voltage power distribution equipment mainly relies on switches such as circuit breakers and fuses for overload protection. However, existing low-voltage power distribution equipment does not have the function of wireless remote monitoring. Staff cannot check the working status of the bus circuit and branch circuit in the low-voltage distribution cabinet in real time. After an electrical accident occurs, it is also difficult to find the fault location, which increases the difficulty of fault diagnosis. When the control components inside the low-voltage distribution cabinet malfunction, the circuit cannot be cut off in time, which can easily cause serious electrical accidents. Therefore, there is a need for a low-voltage power distribution equipment that can be remotely monitored and controlled. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a low-voltage complete power distribution equipment with remote intelligent monitoring capabilities.

[0007] The technical solution of this invention is: a low-voltage complete set of power distribution equipment with remote intelligent monitoring function, including a cabinet. The cabinet contains an incoming line cabinet and a heat dissipation mechanism. The top of the cabinet is equipped with a heat insulation board. Below the incoming line cabinet is a non-contact current and voltage tester. Below the non-contact current and voltage tester is an incoming line meter. Below the incoming line meter is an electrically connected fuse. Below the fuse are multiple branch contactors. Below each branch contactor is an electrically connected branch circuit breaker. The outgoing line of the branch circuit breaker is equipped with... The second non-contact current and voltage tester has an output meter at its lower part, a fire extinguisher slot above the insulation board, a connecting plate on the side of the fire extinguisher slot, two adjusting screws rotatably connected to the connecting plate, the outer side of the adjusting screws being threadedly connected to the fire extinguisher slot, a carbon dioxide fire extinguisher placed in the fire extinguisher slot, a heat insulation protective shell above the insulation board, and a remote monitoring device for remotely transmitting current and voltage parameters on the inner wall of the cabinet, the remote monitoring device being connected to a control terminal via a remote wireless network.

[0008] Furthermore, the remote monitoring device includes a backup battery, which is electrically connected to the branch circuit breaker. The backup battery is electrically connected to a PLC controller and a communication module for wireless network connection with the control terminal. The PLC controller is electrically connected to the non-contact current and voltage tester one, the non-contact current and voltage tester two, the branch contactor, the incoming line meter, and the outgoing line meter.

[0009] Note: The branch circuit contactors are controlled by a PLC controller. Even in the event of a circuit failure, the circuit can be remotely disconnected by the PLC controller, powered by a backup battery, to ensure the safety of the cabinet.

[0010] Furthermore, the incoming line cabinet is equipped with an isolating switch for isolating the power supply and a circuit breaker for cutting off the circuit.

[0011] Note: Maintenance personnel can disconnect the busbar circuit by disconnecting the isolating switch, thus de-energizing each branch circuit and improving maintenance safety. In case of overload, the busbar circuit breaker can automatically disconnect, further enhancing electrical safety.

[0012] Furthermore, a humidity sensor is also provided on the inner wall of the cabinet, and the humidity sensor is electrically connected to the remote monitoring device.

[0013] Note: The humidity sensor detects the humidity of the cabinet to prevent short circuits caused by excessive humidity.

[0014] Furthermore, a busbar contactor is also provided above the incoming line cabinet, and the busbar contactor is electrically connected to the remote monitoring equipment.

[0015] Explanation: The bus contactor is remotely controlled by a remote monitoring device to achieve remote opening and closing of the bus circuit.

[0016] Furthermore, a temperature sensor is also provided on the inner wall of the cabinet, and the temperature sensor is electrically connected to the remote monitoring device.

[0017] Note: The temperature of the cabinet is remotely monitored by a temperature sensor to prevent circuit failures caused by high temperatures inside the cabinet.

[0018] Furthermore, a smoke sensor is installed on the inner wall of the cabinet, and a liquid level sensor is installed at the bottom of the inner wall of the cabinet. Both the smoke sensor and the liquid level sensor are electrically connected to the remote monitoring device.

[0019] Note: The smoke sensor can detect whether there is an open flame in the cabinet. When the smoke sensor detects the inside of the cabinet, rainwater will enter the cabinet in a rainy environment. The liquid level sensor detects the liquid level at the bottom of the cabinet. If the liquid level exceeds the warning level, the circuit of the busbar can be remotely cut off to prevent passers-by from being electrocuted.

[0020] Furthermore, the bottom of the fire extinguisher slot is provided with a through hole one, and the top of the cabinet is provided with a through hole two. The nozzle of the carbon dioxide fire extinguisher extends into the cabinet through through holes one and two. The insulation plate is provided with electric cylinder one and electric cylinder two, which are electrically connected to the PLC controller. The telescopic end of electric cylinder one is connected to the safety pin of the carbon dioxide fire extinguisher, and electric cylinder two is in contact with the pressure handle of the carbon dioxide fire extinguisher.

[0021] Instructions: In the event of a fire inside the cabinet, the PLC controller will activate electric cylinder one to pull out the safety pin of the carbon dioxide fire extinguisher. Electric cylinder two will then activate to compress the handle of the carbon dioxide fire extinguisher, causing carbon dioxide gas to be released to extinguish the fire. The carbon dioxide fire extinguisher can be replaced periodically and is secured by adjusting the screw.

[0022] Furthermore, the heat dissipation mechanism includes an exhaust fan located on the left side of the cabinet and an air inlet pipe connected to the air inlet of the exhaust fan. An air filter is installed inside the air inlet pipe. An exhaust fan is located on the right side of the cabinet. An exhaust fan is connected to the air outlet by an exhaust pipe. An exhaust valve is installed in the middle of the exhaust pipe.

[0023] Explanation: The cooling system ventilates the interior of the cabinet, removing heat and lowering the internal temperature. The air filter reduces the risk of dust entering the cabinet and causing a fire. The bus contactor can be controlled remotely to disconnect the bus circuit.

[0024] Furthermore, the top of the cabinet is equipped with a high-definition camera and a supplementary light for supplementing the high-definition camera, as well as an infrared camera for capturing the heat points inside the cabinet. The high-definition camera, the infrared camera, and the supplementary light are all electrically connected to the remote monitoring device.

[0025] Note: If there are obvious fault points inside the cabinet, they can be viewed remotely directly through a high-definition camera. If an electronic device inside the cabinet is overheating due to a fault, it can also be seen intuitively through an infrared camera.

[0026] The beneficial effects of this invention are:

[0027] This invention monitors low-voltage power distribution equipment remotely. Monitoring data includes cabinet humidity, temperature, liquid level at the bottom of the cabinet, bus current and voltage, and current and voltage of each branch circuit. The monitoring data is comprehensive. Each branch circuit is equipped with a circuit breaker and a branch contactor. In case of overload, the branch circuit breaker trips immediately. If the branch circuit breaker fails to trip, it can be remotely disconnected via the branch contactor. In case of a short circuit, the fuse and circuit breaker will immediately disconnect the bus, ensuring the electrical safety of each branch circuit. This invention can remotely monitor multiple parameters of low-voltage distribution cabinets and remotely disconnect bus and branch circuits, improving the efficiency of low-voltage distribution cabinet fault diagnosis, enhancing the electrical safety of users, and improving the safety of maintenance personnel during maintenance.

Detailed Implementation

[0032] Example 1:

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, a low-voltage complete set of power distribution equipment with remote intelligent monitoring function includes a cabinet 1. Inside the cabinet 1 are an incoming line cabinet 2 and a heat dissipation mechanism 9. A heat insulation board 10 is provided on the top of the cabinet 1. A non-contact current and voltage tester 11 is located below the incoming line cabinet 2. An incoming line meter 12 is located below the non-contact current and voltage tester 11.

The side of the fire extinguisher slot 101... A snap-fit ​​plate 102 is provided, on which two adjusting screws 103 are rotatably connected. The outer side of the adjusting screws 103 is threadedly connected to the fire extinguisher slot 101. A carbon dioxide fire extinguisher 104 is placed in the fire extinguisher slot 101. A heat insulation protective shell 109 is provided above the heat insulation plate 10. The inner wall of the cabinet 1 is provided with a remote monitoring device 3 for remotely transmitting current and voltage parameters. The remote monitoring device 3 is connected to a control terminal 4 via a remote wireless network. (Non-contact current and voltage tester 11, incoming line meter 12, fuse 13, branch contactor 14, branch circuit breaker 15, non-contact current and voltage tester 2 16, outgoing line meter 17, and control terminal 4 are all commercially available products. As long as they can achieve the function of this invention, they are acceptable. Those skilled in the art can choose to use them according to common sense. No special limitation is made here.)

[0034] The remote monitoring device 3 includes a backup battery 31, which is electrically connected to the branch circuit breaker 15. The backup battery 31 is electrically connected to a PLC controller 32 and a communication module 33 for wireless network connection with the control terminal 4. The PLC controller 32 is electrically connected to a non-contact current and voltage tester 11, a non-contact current and voltage tester 2 16, a branch contactor 14, an incoming line meter 12, and an outgoing line meter 17. (The backup battery 31, PLC controller 32, and communication module 33 are all commercially available products. As long as they can achieve the functions of this invention, they are acceptable. Those skilled in the art can choose to use them based on common sense, and no special limitations are made here.)

[0035] The PLC controller 32 controls the opening and closing of the branch contactor 14. Even in the event of a circuit failure, the backup battery 31 provides power, and the PLC controller 32 can remotely disconnect the branch circuit to ensure the safety of the cabinet.

[0036] The incoming line cabinet 2 is equipped with a disconnecting switch 21 for isolating the power supply and a circuit breaker 22 for cutting off the circuit (both the disconnecting switch 21 and the circuit breaker 22 are commercially available products, as long as they can achieve the function of this invention, those skilled in the art can choose to use them based on common sense, and no special limitation is made here).

[0037] Maintenance personnel can disconnect the bus circuit by disconnecting the isolating switch 21, so that the circuits of each branch are de-energized, improving maintenance safety. In case of overload, the bus circuit breaker 22 can automatically disconnect, improving the safety of electricity use.

[0038] Example 2:

[0039] The difference between this embodiment and embodiment 1 is that the inner wall of the cabinet 1 in this embodiment is also provided with a humidity sensor 5, which is electrically connected to the remote monitoring device 3 (the humidity sensor 5 is an existing commercially available product).

[0040] Compared to Embodiment 1, this embodiment can detect the humidity of the cabinet using a humidity sensor 5, thus avoiding short circuits caused by excessive humidity.

[0041] Example 3:

[0042] The difference between this embodiment and embodiment 2 is that a bus contactor 18 is also provided above the incoming line cabinet 2 in this embodiment. The bus contactor 18 is electrically connected to the remote monitoring device 3 (the bus contactor 18 is a commercially available product, as long as it can achieve the function of the present invention. Those skilled in the art can choose to use it based on common sense, and no special limitation is made here).

[0043] Compared to Example 2, this embodiment uses a bus contactor 18 remotely controlled by a remote monitoring device 3 to remotely open and close the bus circuit (the bus contactor 18 is a commercially available product, as long as it can achieve the function of this invention, and those skilled in the art can choose to use it based on common sense, without any special limitations).

[0044] Example 4:

[0045] The difference between this embodiment and embodiment 3 is that the inner wall of the cabinet 1 in this embodiment is also provided with a temperature sensor 6, which is electrically connected to the remote monitoring device 3 (the temperature sensor 6 is a commercially available product, as long as it can achieve the function of the present invention, those skilled in the art can choose to use it according to common sense, and no special limitation is made here).

[0046] Compared to Example 3, this embodiment uses temperature sensor 6 to remotely monitor the temperature of cabinet 1, thus preventing circuit failures caused by high temperatures inside cabinet 1.

[0047] Example 5:

[0048] The difference between this embodiment and embodiment 4 is that the inner wall of the cabinet 1 in this embodiment is provided with a smoke sensor 7 and the bottom of the inner wall of the cabinet 1 is provided with a liquid level sensor 8. Both the smoke sensor 7 and the liquid level sensor 8 are electrically connected to the remote monitoring device 3 (the liquid level sensor 8 is a commercially available product, as long as it can achieve the function of the present invention, those skilled in the art can choose to use it according to common sense, and no special limitation is made here).

[0049] Compared to Example 4, in this embodiment, the smoke sensor 7 can detect whether there is an open flame in the cabinet 1. When the smoke sensor 7 detects a fire inside the cabinet 1, the bus contactor 18 can be controlled by the remote monitoring device 3 to disconnect the bus circuit. In a rainy environment, rainwater will enter the cabinet 1. The liquid level sensor 8 detects the liquid level at the bottom of the cabinet 1. After the liquid level exceeds the warning level, the bus circuit can be remotely cut off to prevent passersby from being electrocuted.

[0050] Example 6:

[0051] The difference between this embodiment and embodiment 5 is that the bottom of the fire extinguisher slot 101 in this embodiment is provided with a through hole 105, and the top of the cabinet 1 is provided with a through hole 106. The nozzle of the carbon dioxide fire extinguisher 104 extends into the cabinet 1 through through holes 105 and 106. The insulation plate 10 is provided with electric cylinder 107 and electric cylinder 108, which are electrically connected to the PLC controller 32. The telescopic end of electric cylinder 107 is connected to the safety pin of the carbon dioxide fire extinguisher 104, and electric cylinder 108 is in contact with the handle of the carbon dioxide fire extinguisher 104. (Electric cylinder 107, electric cylinder 108, and carbon dioxide fire extinguisher 104 are all commercially available products. As long as they can achieve the function of this invention, they are acceptable. Those skilled in the art can choose to use them based on common sense. No special limitation is made here.)

[0052] Compared to Example 5, in this example, when a fire breaks out inside the cabinet, the PLC controller 32 controls the electric cylinder 107 to work, pulling out the safety pin of the carbon dioxide fire extinguisher 104. The electric cylinder 108 then works to squeeze the handle of the carbon dioxide fire extinguisher 104, causing carbon dioxide gas to be sprayed out to extinguish the fire. The carbon dioxide fire extinguisher 104 can be replaced periodically, and the carbon dioxide fire extinguisher is fixed by adjusting the screw 103.

[0053] Example 7:

[0054] The difference between this embodiment and embodiment 6 is that the heat dissipation mechanism 9 in this embodiment includes an exhaust fan 91 located on the left side of the cabinet 1, and an air inlet pipe 92 connected to the air inlet of the exhaust fan 91. An air filter element 93 is provided inside the air inlet pipe 92. An exhaust fan 94 is located on the right side of the cabinet 1. An exhaust pipe 95 is connected to the air outlet of the exhaust fan 94. An exhaust valve 96 is provided in the middle of the exhaust pipe 95. (The exhaust fan 91, the exhaust valve 96, and the air filter element are all commercially available products. As long as they can achieve the function of this invention, they are acceptable. Those skilled in the art can choose to use them based on common sense. No special limitations are made here.)

[0055] Compared to Embodiment 6, this embodiment uses the heat dissipation mechanism 9 to ventilate the interior of the cabinet 1, thereby removing heat from the cabinet 1 and reducing the temperature inside the cabinet 1. The air filter 93 can reduce the amount of dust entering the interior of the cabinet 1.

[0056] Example 8:

[0057] The difference between this embodiment and embodiment 7 is that the top of the cabinet 1 in this embodiment is provided with a high-definition camera 19 and a supplementary light 191 for supplementing the high-definition camera 19, as well as an infrared camera 192 for capturing the heat points inside the cabinet 1. The high-definition camera 19, the infrared camera 192, and the supplementary light 191 are all electrically connected to the remote monitoring device 3 (the supplementary light 191, the infrared camera 192, and the high-definition camera 19 are all commercially available products. As long as they can achieve the function of this invention, they are acceptable. Those skilled in the art can choose to use them based on common sense, and no special limitation is made here).

[0058] Compared to Example 7, in this example, if there is an obvious fault location, it can be directly viewed remotely through a high-definition camera. If an electronic device in cabinet 1 malfunctions and overheats, it can also be seen intuitively through infrared camera 192.

[0059] The operating method of a low-voltage complete set of power distribution equipment with remote intelligent monitoring function in Embodiment 8 above includes the following steps:

[0060] S1. The working status of the bus contactor 18 and branch contactor 14 in the cabinet is remotely monitored and controlled through the control terminal 4, thereby controlling the opening and closing of the bus circuit and branch short circuit; the non-contact current and voltage tester 11 and the non-contact current and voltage tester 2 16 are used to monitor the current and voltage parameters of the bus circuit and the current and voltage parameters of the branch circuit, respectively; the incoming line meter 12 is used to monitor the power consumption of the bus circuit; the power consumption of each branch circuit is monitored through the outgoing meter 17; the control terminal 4 is implemented in the form of a computer client or mobile APP.

[0061] S2. When the branch current is overloaded, the branch circuit breaker 15 trips, disconnecting the branch circuit. When the bus current is overloaded, the fuse 13 and circuit breaker 22 operate, disconnecting the bus circuit. When staff need to maintain the equipment, they can manually disconnect the bus circuit through the isolating switch. When a circuit fault requires disconnecting the branch circuit or the bus circuit, the control command can be remotely sent to the communication module 33 through the control terminal 4. The communication module 33 then sends the control command to the PLC controller. The PLC controller controls the bus contactor 18 or the branch contactor 14 to operate, thereby achieving the closing of the bus circuit or the branch circuit.

[0062] S3. The humidity, temperature, smoke and bottom liquid level in the cabinet are monitored by humidity sensor 5, temperature sensor 6, smoke sensor 7 and liquid level sensor 8 respectively. The heat dissipation mechanism 9 realizes heat dissipation inside the cabinet 1. If there is an obvious fault point in the cabinet 1, it can be viewed directly remotely by high-definition camera 19. If an electronic device in the cabinet 1 is overheating due to a fault, it can also be seen intuitively by infrared camera 192.
