Description

Technical Field

[0001] This utility model belongs to the field of high-voltage power distribution technology, and in particular relates to a high-voltage power distribution device with human-computer interaction capability. Background Technology

[0002] As a core component of high-voltage power distribution equipment, the reliable operation of the three-position mechanism is crucial for the safe operation of the equipment. Currently, there are three main methods for operating the three-position mechanism: first, remote operation from above ground via a protector in the high-voltage power distribution equipment; second, active control of the three-position mechanism when the protector detects an anomaly; and third, local operation by the operator via physical buttons. However, the third method of local operation poses a risk of electric shock to the operator in harsh environments (such as humid conditions or high electromagnetic interference), making it unsafe. Utility Model Content

[0003] Based on this, and to address the aforementioned technical problems, a high-voltage power distribution device with human-computer interaction is provided.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A high-voltage power distribution device with human-machine interaction includes a housing and a protector and a three-position mechanism disposed within the housing. The protector is controlled and connected to a controller of the three-position mechanism. The device further includes a human-machine interaction device, which includes a voice interaction module. The inner cavity of the housing is divided into an explosion-proof cavity and an intrinsically safe cavity by a partition. The partition has a wiring through-hole connecting the explosion-proof cavity and the intrinsically safe cavity. The protector and the three-position mechanism are disposed within the explosion-proof cavity, and the human-machine interaction device is disposed within the intrinsically safe cavity. A side plate of the housing corresponding to the intrinsically safe cavity has an interaction port communicating with the intrinsically safe cavity. The human-machine interaction device is communicatively connected to the protector via a first communication line passing through the wiring through-hole.

[0006] The beneficial effects of this utility model are as follows:

[0007] 1. Improved operational safety: By setting up a human-machine interaction device, operators can control the three-station mechanism through non-contact human-machine interaction (voice commands), avoiding the risk of electric shock caused by harsh environments when operating on-site with traditional physical buttons.

[0008] 2. Reduce electromagnetic interference: The human-machine interface device is placed inside the intrinsically safe cavity and separated from the protector, three-position mechanism and circuit breaker mechanism inside the explosion-proof cavity by a partition. It is connected only by a communication line through the wiring through hole, which effectively isolates the electromagnetic interference generated by the explosion-proof cavity, and can significantly improve the recognition accuracy and stability of the voice interaction module.

[0009] 3. Reasonable structural layout: The separate cavity design of the explosion-proof cavity and the intrinsically safe cavity not only ensures the explosion-proof requirements of the core components of the high-voltage power distribution equipment (protectors, three-position mechanisms, circuit breakers), but also provides a safe and low-interference operating environment for human-machine interaction devices that are sensitive to the electromagnetic environment, thus taking into account both the safety of the equipment and the ease of operation.

[0010] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0011] Figure 1 This is a front view structural diagram of the present invention;

[0012] Figure 2 for Figure 1 AA section view;

[0013] Figure 3 This is a schematic diagram of the reverse side of the front panel of the housing of this utility model;

[0014] Figure 4 This is the electrical schematic diagram of this utility model. Detailed Implementation

[0015] like Figure 1 and Figure 2 As shown in the figure, this specification provides a high-voltage power distribution equipment with human-machine interaction, including a housing 110, a three-position mechanism 120, a circuit breaker mechanism 130, a protector 140, a human-machine interaction device 150, and a camera 160.

[0016] like Figure 2 As shown, the front panel 111 of the housing 110 is a cabinet door, and a cover-shaped partition 112 is welded to the upper part of its inner surface, dividing the inner cavity of the housing 110 into an explosion-proof cavity 113 and an intrinsically safe cavity 114.

[0017] The upper part of the front panel 111, corresponding to the intrinsically safe cavity 114, has an interaction port, which consists of a display window 111a, a speaker 111b, and a keyboard port 111c. (See attached image) Figure 1 .

[0018] like Figure 3 As shown, the partition 112 has a wiring through hole 112a that connects the explosion-proof cavity 113 and the intrinsically safe cavity 114.

[0019] The three-position mechanism 120, circuit breaker mechanism 130, and protector 140 are all located within the explosion-proof chamber 113. The protector 140 is connected to the controllers of the three-position mechanism 120 and the circuit breaker mechanism 130. All three are existing components of the high-voltage power distribution equipment; their functions will be described separately below.

[0020] The three-position mechanism 120 integrates the functions of both a disconnector and a grounding switch, all performed by a single switch blade. This achieves mechanical interlocking and prevents the grounding switch from being closed while the main circuit is energized. Unlike traditional disconnectors where the main switch and grounding switch are separate and prone to misoperation, the three-position mechanism 120 uses a single switch blade, whose working position is unique at any given time—either in the main switch closed position, the disconnector position, or the grounding position. The mechanism is driven by operating motors (grounding motor and disconnector motor).

[0021] Circuit breaker mechanism 130: Circuit breaker mechanism 130 is mainly responsible for the mechanical opening and closing of electrical circuits. Its operating mechanism consists of a closing mechanism, a tripping mechanism, and related circuits. After receiving a closing command from the closing button on the high-voltage power distribution equipment door or the protector 140, the circuit breaker mechanism 130 initiates the closing operation, closing the closing circuit, energizing the closing coil, and driving the closing mechanism to operate, thereby closing the high-voltage power distribution equipment. After receiving a tripping command from the tripping button on the high-voltage power distribution equipment door or the protector 140 detects a fault, the circuit breaker mechanism 130 initiates the tripping operation, disconnecting the tripping circuit, energizing the tripping coil, and driving the tripping mechanism to operate, thereby tripping the high-voltage power distribution equipment.

[0022] Protector 140 is an important component of high-voltage power distribution equipment. It can collect and calculate the voltage and current in the high-voltage power distribution equipment, perform circuit breaker opening and closing operations, and promptly disconnect the circuit when short circuit, overload, or overvoltage faults are detected in the power supply system line or load to prevent the fault from escalating. It also isolates and grounds the three-position mechanism 120, monitors the temperature of the switch contacts in real time, provides early warnings and trips through fault diagnosis, and provides big data analysis and judgment for fault diagnosis by accessing data from various IoT sensors.

[0023] like Figure 1 and Figure 3 As shown, the human-computer interaction device 150 includes a voice interaction module 151, an interactive display screen 152, and an operation keyboard 153.

[0024] The voice interaction module 151 is integrated into the interactive display screen 152. Its voice input microphone is located on the front of the interactive display screen 152. The interactive display screen 152 and the operation keyboard 153 are both fixed in the intrinsically safe cavity 114 and are respectively fitted with the display window 111a and the keyboard port 111c. The operation keyboard 153 is communicatively connected to the interactive display screen 152. The speaker of the voice interaction module 151 is located inside the speaker port 111b.

[0025] The voice interaction module 151 has a voice recognition chip, supports natural language command input and status feedback, and includes functions such as voice acquisition, voice processing, voice execution and TTS. Users can input commands through the voice interaction module 151.

[0026] Users can also input commands through the interactive display screen 152, which supports touch screen operation or operation via the keyboard 153.

[0027] The interactive display screen 152 is connected to the protector 140 via a first communication line 170 passing through the wiring through hole 112a. The commands input by the user through the voice interaction module 151 or the interactive display screen 152 are transmitted to the protector 140 via the first communication line 170.

[0028] The aforementioned human-computer interaction device 150 is located inside the intrinsically safe cavity 114, which can effectively avoid electromagnetic interference from the explosion-proof cavity 113, and in particular improve the accuracy of voice recognition.

[0029] Camera 160 is a 4-megapixel industrial-grade wide-angle camera with infrared fill light function. It is located in an area far away from strong electromagnetic interference inside the explosion-proof cavity 113, and its lines are grounded to avoid the influence of electromagnetic interference.

[0030] Camera 160 is connected to interactive display screen 152 via a second communication line 180 passing through wiring hole 112a. It captures real-time video of the contact points of the execution unit of the three-station mechanism 120 and sends it to the interactive display screen 152. The internal chip of the interactive display screen 152 acts as a vision recognition chip, visually recognizing the operation results of the three-station mechanism 120 based on the real-time video and feeding this information back to the protector 140. Alternatively, the vision recognition chip can operate independently of the interactive display screen 152; for example, the processor inside the protector 140 can serve as the vision recognition chip.

[0031] Both the first communication line 170 and the second communication line 180 are shielded network cables, which can suppress the impact of electromagnetic interference on communication. The connection between the two and the wiring through hole 112a is sealed with sealant using explosion-proof equipment, which can effectively block electromagnetic interference.

[0032] Taking voice interaction as an example, when an operator needs to operate the three-station mechanism 120, they first wake up the device with voice commands. For example, if the operator says "device name 621", the device with the number 621 will reply "I am here". Then, the operator says "switch to cold standby". The voice interaction module 151 converts the operator's voice into control commands and sends them to the controller of the three-station mechanism 120. The controller controls the execution unit to perform the corresponding operation according to the command and feeds back the operation results to the processor inside the protector 140 based on the contact sensors and other devices. At the same time, the vision recognition chip visually recognizes the operation results of the three-station mechanism 120 based on the real-time video captured by the camera 160 and feeds them back to the processor inside the protector 140. The processor makes a comprehensive judgment on the operation results based on the operation results fed back by the vision recognition chip and the operation results fed back by the controller of the three-station mechanism 120 and feeds them back to the voice interaction module 151. The voice interaction module 151 converts the results into audio and plays it back to the operator via TTS.

[0033] Specifically, the aforementioned visual recognition uses a visual recognition model (such as a neural network model) to identify whether the contact point is in place, whether the contact temperature exceeds the limit, and whether it is stuck or damaged. This can be achieved by training the visual recognition model with corresponding sample images. This is a conventional technical method and will not be elaborated on in detail.

[0034] As can be seen from the above, the high-voltage power distribution equipment with human-computer interaction provided in this application has the following beneficial effects:

[0035] 1. Improved operational safety: By setting up a human-machine interaction device, operators can control the three-station mechanism through non-contact human-machine interaction methods (such as voice commands), avoiding the risk of electric shock caused by harsh environments when operating on-site with traditional physical buttons.

[0036] 2. Reduce electromagnetic interference: The human-machine interface device is placed inside the intrinsically safe cavity and separated from the protector, three-position mechanism and circuit breaker mechanism inside the explosion-proof cavity by a partition. It is connected only by a communication line through the wiring through hole, which effectively isolates the electromagnetic interference generated by the explosion-proof cavity, and can significantly improve the recognition accuracy and stability of the voice interaction module.

[0037] 3. Reasonable structural layout: The separate cavity design of the explosion-proof cavity and the intrinsically safe cavity not only ensures the explosion-proof requirements of the core components of the high-voltage power distribution equipment (protectors, three-position mechanisms, circuit breakers), but also provides a safe and low-interference operating environment for human-machine interaction devices that are sensitive to the electromagnetic environment, thus taking into account both the safety of the equipment and the ease of operation.

[0038] 4. The method of obtaining a comprehensive judgment result by combining the operation results fed back by the visual recognition chip and the operation results fed back by the controller of the three-station mechanism eliminates the possibility of misjudgment caused by the reflection interference of metal components and visual blind spots during manual inspection, making it safe and efficient.

[0039] However, those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any changes or modifications to the above embodiments within the scope of the essential spirit of the present utility model will fall within the scope of the claims of the present utility model.
