Description

Technical Field

[0001] This invention relates to the field of power system and automation technology, specifically to a self-detecting fire-prevention intelligent power transmission and distribution control device. Background Technology

[0002] Intelligent power distribution systems are intelligent control devices used for power transmission, distribution, and system protection. They mainly include core components such as transformers, switching equipment, and protective relays, and ensure the stable operation of the power grid through functions such as voltage regulation and fault isolation.

[0003] The self-detecting fire-prevention intelligent power transmission and distribution control equipment is a power equipment safety system that integrates intelligent linkage functions such as electrical control and fire monitoring for intelligent power distribution systems. It is mainly used in intelligent distribution cabinets, substations and other scenarios, and aims to prevent electrical fires and achieve rapid response to fires.

[0004] However, the existing self-detecting fire-prevention intelligent power transmission and distribution control device has the following shortcomings: 1) Existing self-detection fire prevention intelligent power transmission and distribution control equipment usually relies solely on traditional temperature sensors to detect temperature. However, temperature sensors have significant limitations. On the one hand, temperature sensors only trigger alarms after the cable temperature rises significantly. During the process of the cable going from overload to a sudden temperature rise, the insulation layer has already aged due to long-term heat accumulation. At the same time, traditional temperature sensors are usually arranged at a single point and cannot completely cover the cable, making it impossible to detect local anomalies. On the other hand, non-fault factors such as fluctuations in ambient temperature can cause false alarms from temperature sensors. Furthermore, the failure to accurately identify local deformation anomalies in the cable can lead to missed alarms, which increases the risk of human misjudgment. 2) Traditional power transmission and distribution systems typically rely on protective devices such as circuit breakers and fuses to cut off circuits. However, these devices have high operating thresholds and long response times, making it impossible to quickly cut off circuits. If equipment such as transformers and distribution cabinets are subjected to abnormal currents for a long time, their internal components may suffer serious risks such as insulation breakdown and explosion due to overheating. At the same time, when abnormal situations occur, it is usually necessary for staff to confirm on-site and manually cut off the power supply. However, in some unattended scenarios, the delay in manual intervention can lead to the deterioration of the accident.

[0005] Therefore, we propose a self-detecting fire-prevention intelligent power transmission and distribution control device to solve the problems mentioned above. Summary of the Invention

Moreover, this disconnection action is usually achieved through mechanical linkage, which has the advantage of fast response time, reduces the delay of manual intervention, and successfully prevents the accident from deteriorating in a short period of time.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: This example mainly addresses the limitations of self-detecting fireproof intelligent power transmission and distribution control equipment that relies solely on temperature sensors for detection. The temperature sensor only triggers the alarm after the temperature of cable 612 rises significantly. However, during the process of cable 612 going from overload to a sudden temperature rise, the insulation layer has already aged due to long-term heat accumulation. At the same time, traditional temperature sensors are usually arranged at a single point and cannot completely cover cable 612, making it impossible to detect local abnormalities. This embodiment addresses the problems of the prior art by incorporating a deformation-sensing cable clamp assembly 6. When mechanical stress causes local deformation of the cable 612 to exceed a threshold, the metal ring 610 deforms along with the cable 612. A strain gauge 611 converts this deformation into an electrical signal, transforming the deformation of the metal ring 610 into a change in resistance, and thus outputting an electrical signal. This enables real-time monitoring of morphological anomalies caused by mechanical stress. Simultaneously, short circuits and overheating within the cable 612 initially manifest as localized volume expansion. The combination of a micro-airbag 606 and a pressure sensor 607 allows for the detection of these expansions via air pressure. By monitoring pressure changes, this system can detect latent faults in advance and prevent serious accidents such as fires and electrical leaks caused by the expansion of internal faults. The two monitoring methods mentioned above constitute a dual deformation monitoring system, which targets the changes in mechanical stress and thermal expansion and contraction of cable 612 respectively. It can cover the main types of deformation risks that cable 612 may encounter during operation. Through the dual deformation monitoring system, it can not only detect the obvious deformation caused by external mechanical force or temperature changes in time, but also capture the latent swelling caused by internal faults. This greatly improves the accuracy and comprehensiveness of identifying abnormal states of cable 612, and provides a reliable basis for subsequent early warning and linkage disconnection.

[0023] Please see Figures 1-3 As shown, the present invention provides a technical solution: a self-detecting fireproof intelligent power transmission and distribution control device, including a deformation sensing cable clamp assembly 6, a linkage cutting assembly 7, and two fixing plates 1. The deformation sensing cable clamp assembly 6 and the linkage cutting assembly 7 are respectively installed between the outer walls of the two fixing plates 1, and the linkage cutting assembly 7 is installed on one side of the outer wall of the deformation sensing cable clamp assembly 6.

[0024] A housing 2 is bolted between the outer walls of the two fixed plates 1. A cabinet door 3 is movably connected to one side of the outer wall of the housing 2. A back plate 4 is bolted to one side of the inner wall of the housing 2. A connector 5 is connected to one side of the outer wall of the back plate 4.

[0025] In use, first determine the specific installation positions of the two fixing plates 1, and then fully fix the fixing plates 1 to the wall or supporting structure. After the two fixing plates 1 are fixed to the wall, fix the shell 2 between the two fixing plates 1 with bolts, and install the cabinet door 3 and the back plate 4 in sequence. Then, a connector 5 is connected to one side of the outer wall of the back plate 4. The accurate installation of the fixing plates 1 can provide effective support to the connected components. The purpose is to ensure the stable operation of the deformation sensing cable clamp assembly 6 and the linkage cutting assembly 7. The linkage cutting assembly 7 directly receives the threshold signal of the linkage cutting assembly 7 through the control system. No manual intervention is required. The entire process from detecting abnormality to executing the cut-off is automated, avoiding operation delays caused by human judgment.

[0026] In some embodiments, according to 1- Figure 9 As shown, the deformation sensing cable clamp assembly 6 includes four sets of micro-airbags 606, four pressure sensors 607, two metal rings 610, and a cable 612. The four sets of micro-airbags 606 are filled with high-purity nitrogen gas and are used to accurately capture the mechanical deformation of the cable 612. The four pressure sensors 607 are used to convert gas pressure changes into electrical signals. The two metal rings 610 are used to sense the mechanical and thermal deformation of the cable 612. Strain gauges 611 are installed on the outer surface of the two metal rings 610 and are used to monitor resistance changes.

[0027] The deformation sensing cable clamp assembly 6 also includes two clamps 601, which are symmetrically arranged and connected together with bolts. The inner walls of the two clamps 601 are connected to two sets of limiting sleeves 602, and the inner surfaces of the four sets of limiting sleeves 602 are elastically connected to a first spring 603.

[0028] Each set of first springs 603 has a soft pad 604 elastically connected to one side of its outer wall. Every two soft pads 604 are symmetrically arranged and tightly fitted. An annular groove 605 is opened on one side of the outer wall of each of the four soft pads 604. The inner surface of each of the four annular grooves 605 is connected to one side of the outer wall of the four sets of micro airbags 606.

[0029] Each of the four micro-airbags 606 has a capillary tube connected to one side of its outer wall, and the four capillary tubes are fully inserted into the interior of a corresponding soft pad 604. Each of the four soft pads 604 has a side of its outer wall connected to one side of its outer wall connected to a pressure sensor 607, and each of the four pressure sensors 607 is connected to a corresponding set of capillary tubes.

[0030] Both sides of the inner wall of the two clamps 601 are connected to L-shaped frames 608. Each pair of L-shaped frames 608 has a fixing sleeve 609 symmetrically inserted into its outer wall. One side of the outer wall of each fixing sleeve 609 is connected to the outer surface of a metal ring 610. The four sets of micro airbags 606 and the outer surface of the cable 612 are in full contact. There is a ring of movement space between the inner surface of the two metal rings 610 and the outer surface of the cable 612. The two metal rings 610 are placed symmetrically and connected by bolts.

[0031] During use, in the preparation stage, firstly, the two clamps 601 are connected and the cable 612 is placed in the middle position. Next, the cable 612 is wrapped around the clamps. Then, annular grooves 605 are opened on one side of the outer wall of each of the four soft pads 604, and the inner surface of the four annular grooves 605 is connected to one side of the outer wall of the four sets of micro-airbags 606, thus facilitating the installation of the four sets of micro-airbags 606. The micro-airbags 606 are made of temperature-resistant and aging-resistant elastic material, and are filled with high-purity nitrogen. During installation, they are tightly attached to the outer surface of the cable 612. (Pressure sensor) 607 (employing a MEMS miniature pressure sensor 607 with an accuracy of ±0.1 kPa) is connected to the micro-inflator 606, enabling real-time monitoring of pressure changes within the micro-inflator 606. The elastic properties of the micro-inflator 606 amplify minute volume changes into detectable pressure changes. Furthermore, the two metal rings 610, made of an elastic alloy and C-shaped structure, are designed to fit against the surface of the cable 612. During installation, the bolts are pre-tightened to encircle the cable 612, ensuring a small space of movement between the two metal rings 610 and the outer surface of the cable 612. The minute deformation of the cable 612 is synchronously transmitted to the metal ring 610, causing it to deform by the same amount. Strain gauges 611 are attached to the outside of the metal ring 610. When the metal ring 610 deforms along with the cable 612, the metal foil of the strain gauge 611 is stretched, and the change in resistance is directly proportional to the degree of deformation. During long-term use, when the cable 612 is subjected to mechanical force or temperature changes, the deformation of the cable 612 causes the metal ring 610 to deform synchronously. The strain gauge 611 converts this deformation into a resistance signal, which is transmitted in real time. When a fault occurs inside the cable 612, such as a short circuit or swelling caused by insulation aging, the cable 612 expands and compresses the micro-airbag 606. At this time, the internal air pressure of the micro-airbag 606 increases, and the pressure sensor 607 transmits the air pressure signal to the control system in real time. The control system processes and distinguishes between the two sets of signals. When one set of signals exceeds the danger threshold, the control system determines it to be an emergency fault and immediately sends a cut-off command to the linkage cut-off component 7. Then, the linkage cut-off component 7 cuts off the cable 612 to eliminate the hidden danger.

[0032] It should be noted that the deformation sensing cable clamp assembly 6, on the one hand, utilizes the strain gauge 611 built into the deformation sensing cable clamp assembly 6 to monitor the local deformation of the cable 612 caused by mechanical stress such as tension, compression, vibration or thermal expansion and contraction in real time. When the deformation exceeds the preset threshold, an early warning signal is immediately issued. On the other hand, the micro airbag 606 combined with the pressure sensor 607 accurately captures the volume expansion of the cable 612 caused by overheating, internal insulation aging or fault, and can provide early warning of risks such as insulation damage and overheating fire. It can successfully avoid problems such as insulation layer damage, internal wire breakage or poor contact caused by excessive deformation of the cable 612, and can prevent safety hazards such as short circuits and leakage in advance. By sensing the deformation difference at different locations, it can quickly locate the specific point of abnormal stress on the cable 612, helping staff to quickly locate the source of the fault, reduce troubleshooting time, and successfully reduce labor and time costs.

[0033] Example 2: This example mainly addresses the problem that in existing self-detecting fireproof intelligent power transmission and distribution control equipment, traditional power transmission and distribution systems usually rely on protection devices such as circuit breakers and fuses to cut off the circuit. However, such devices have high action thresholds and long response times, making it impossible to quickly cut off the circuit. This embodiment is completed to solve the problem of the prior art. It is equipped with a linkage cut-off component 7, which can be linked with the deformation sensing cable clamp component 6. When the deformation signal triggers the danger threshold, the linkage cut-off component 7 automatically performs the cut-off action to quickly cut off the power supply and prevent short circuit fires, equipment overload damage or electric shock accidents caused by cable 612 damage, thereby forming a complete protection chain of monitoring, early warning and cut-off.

[0034] In some embodiments, according to 1- Figure 4 as well as Figures 10-13 As shown, the linkage cutting assembly 7 includes a gear reducer 705, which is used to amplify torque. The rotating end of the gear reducer 705 is connected to a cam 706. An irregular circular groove is provided on one side of the outer wall of the cam 706. A roller 719 is movably connected to the inner surface of the irregular circular groove. The cam 706 drives the roller 719 to convert the rotational motion into linear motion.

[0035] The linkage cutting assembly 7 also includes a support base 701. One side of the outer wall of the support base 701 is bolted to one side of the outer wall of the back plate 4. Four brackets 702 are connected to the top of the support base 701. A servo motor 703 is fixedly installed on the top of the four brackets 702. The shaft end of the servo motor 703 is rotatably connected to the power input end of the gear reducer 705. Four support frames 704 are connected to the top of the support base 701. The top of the four support frames 704 is connected to the bottom of the gear reducer 705.

[0036] The top of the support base 701 is fixedly connected to two metal plates 707. Each of the outer walls of the two metal plates 707 has a groove. The inner walls of the two grooves are slidably connected to a slide table 710. The top of the slide table 710 is connected to two sliding columns 709. The top of the two metal plates 707 is fixedly connected to a support platform 708. The two sliding columns 709 pass through the top of the support platform 708.

[0037] The top of the support platform 708 is bolted to a lower tool holder 715. A passive tool 716 is fixedly installed on the top of the lower tool holder 715. Four buffer sleeves 717 are fixedly connected to the top of the lower tool holder 715. The bottom of the inner wall of each of the four buffer sleeves 717 is elastically connected to a second spring 718. The top of the two sliding columns 709 is fixedly connected to a top plate 711.

[0038] The bottom of the top plate 711 is bolted to an upper tool holder 712. An active tool 713 is installed at the bottom of the upper tool holder 712. Four solid columns 714 are connected to the bottom of the upper tool holder 712, and the diameter of the four solid columns 714 is smaller than the inner surface diameter of the four buffer sleeves 717. A metal rod is fixedly inserted into one side of the outer wall of the slide table 710. The outer surface of the metal rod is connected to the inner surface of the roller 719. There is a ring of movement space between the active tool 713 and the passive tool 716, and the cable 612 is inserted between the active tool 713 and the passive tool 716.

[0039] In use, the above components form a complete linkage cutting assembly 7. First, with the cable 612 in a safe state, the upper blade holder 712 drives four solid pillars 714 and the lower blade holder 715, along with its top second spring 718, in an elastic connection. Under the force of the second spring 718, the upper blade holder 712 and the active blade 713 are lifted, creating a space between the active blade 713 and the passive blade 716. The cable 612 passes between the active blade 713 and the passive blade 716. During long-term use, when the cable 612 is subjected to mechanical force or temperature changes, the dual deformation monitoring system in the deformation sensing cable clamp assembly 6 detects that the deformation of the cable 612 exceeds a preset danger threshold. At this time, the control system sends an electrical signal command to the controller of the linkage cutting assembly 7, instructing it to perform a cutting action. Upon receiving the signal, the controller immediately starts the servo motor 703 by connecting to the power supply. The rotational power output by the servo motor 703 then enters the gear reducer. Speed ​​reducer 705, after being reduced in speed and increased in torque by gear reducer 705, drives cam 706 to start rotating. When cam 706 starts rotating, the irregular circular groove on its outer wall is in continuous contact with roller 719. When the protruding section of cam 706 contacts roller 719, roller 719 is moved downward. At this time, slide table 710 descends synchronously along the slide rail on one side of the outer wall of the two metal plates 707. Sliding column 709 moves downward synchronously with slide table 710, driving the top active blade 713 towards the passive blade 716. As the cutting progresses, the active blade 713 moves downward under the influence of the sliding column 709 until it fully engages with the cutting edge of the passive blade 716, applying sufficient shearing force to the cable 612 in the middle and cutting it off. At this time, the cam 706 drives the roller 719 to rotate to the concave section of the cam 706. Under the action of the second spring 718, the upper blade holder 712 and the active blade 713 are pushed up again. At this time, the control system issues a stop command to shut down the servo motor 703, thereby completing the cutting task.

[0040] It should be noted that the linkage disconnection component 7 can be linked with the deformation sensing cable clamp component 6. When the deformation signal triggers the danger threshold, the linkage disconnection component 7 automatically performs the disconnection action to quickly cut off the power supply and prevent short circuit fires, equipment overload damage, or electric shock accidents caused by cable 612 damage. This forms a complete protection chain of monitoring, early warning, and disconnection. Moreover, this disconnection action is usually achieved through mechanical linkage, which has the advantage of fast response time, reduces the delay of manual intervention, and successfully prevents the accident from deteriorating in a short period of time.

[0041] In a more specific embodiment, the final result of combining the deformation-sensing cable clamp assembly 6 described in Embodiment 1 and the linkage cutting assembly 7 described in Embodiment 2 is as follows: When the deformation sensing cable clamp assembly 6 is running, if the deformation sensing system of the deformation sensing cable clamp assembly 6 detects the deformation of the metal ring 610 by strain gauge 611 and the pressure sensor 607 detects the pressure of the micro-airbag 606, and detects that the deformation of the cable 612 exceeds the preset danger threshold, the control system will send an electrical signal command to the controller of the linkage cutting assembly 7 to indicate that a cutting action needs to be performed. At this time, the servo motor 703 is immediately started by connecting the power supply. The rotational power output by the servo motor 703 enters the gear reducer 705. After being reduced in speed and amplified in torque by the gear reducer 705, the cam 706 starts to rotate. When the cam 706 starts to rotate, the irregular circular groove on its outer wall is in continuous contact with the roller 719. When the protruding section of the cam 706 and the roller 719 rotate, the cam 706 starts to rotate. When roller 719 contacts, roller 719 moves downward. At this time, slide table 710 descends synchronously along the slide rail on one side of the outer wall of the two metal plates 707. Slide column 709 moves downward synchronously with slide table 710, driving the top active blade 713 to move closer to passive blade 716. Driven by slide column 709, active blade 713 continues to move downward until it fully engages with the cutting edge of passive blade 716, applying sufficient shearing force to the middle cable 612 and cutting the cable 612. At this time, cam 706 drives roller 719 to rotate to the concave section of cam 706. Under the action of the elastic force of second spring 718, the upper blade holder 712 and active blade 713 are pushed up again. At this time, the control system issues a stop command to shut down servo motor 703, thereby completing the cutting task.

[0042] In summary, the entire workflow revolves around real-time monitoring, dynamic judgment, immediate execution, and state closure. The deformation sensing cable clamp assembly 6 is responsible for detecting problems, while the linkage disconnection assembly 7 is responsible for solving them. The control system achieves seamless integration between the two through signal transmission and command triggering, ultimately realizing active protection of cable 612 and avoiding safety accidents caused by deformation.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
