Abstract

The present invention relates to the technical field of distribution network monitoring, and specifically to an intelligent monitoring system for a distribution network, which includes a cable temperature control monitoring screen, a joint flame retardant mechanism installed inside a transformer joint, a temperature control mechanism installed on the joint flame retardant mechanism, two electromagnetic position control mechanisms installed on the joint flame retardant mechanism, and a wire installation mechanism installed inside the joint flame retardant mechanism. By setting the traditional direct connection mode between the output line and the transformer joint to a multi-stage transfer mode, an independent temperature control mechanism is provided between the exposed core wire of the output line and the transformer joint, and the joint flame retardant mechanism is used to provide flame retardant protection between the output line and the transformer joint.

Description

Technical Field

[0001] The present invention relates to the technical field of distribution network monitoring, and in particular to an intelligent monitoring system for a distribution network. Background Technique

[0002] Electricity, as the main energy source in today's society, plays an extremely important role in the development of the national economy and the improvement of people's living standards. The modern power system is a large system composed of the links of electricity generation, transmission, distribution, and consumption. With the gradual development of the intelligent power system, a highly flexible data-driven power supply will gradually replace the traditional static power supply. Through the mining and analysis of massive data, the management of power production supply and demand becomes more effective, so it is extremely necessary to set up an intelligent monitoring system for the distribution network.

[0003] However, there are still many potential safety hazards in the traditional power operation system. The biggest potential safety hazard in the distribution network is the lack of effective monitoring between the transformer and the output line. Due to the insufficient tightness of the connection between the transformer joints and each output line by the workers, and the interference of the surrounding environmental factors of the transformer on the joints and lines, as the electricity consumption of users increases in the hot summer, the connection between the transformer joints and the output lines is likely to melt due to temperature rise. In severe cases, the insulating layer of the output line will spontaneously ignite, and then the transformer will explode due to open fire and other dangerous accidents.

[0004] In view of this, the present invention designs an intelligent monitoring system for a distribution network to monitor the safety between the transformer and the output line in real time to solve the above problems. Summary of the Invention

At this time, the conductive joint and the conductive piece will quickly maintain a safe gap, thereby avoiding serious accidents such as spontaneous combustion of the output line and the transformer joint.

[0051] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific implementation manners and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0052] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0053] The following describes a smart monitoring system for a distribution network provided by some embodiments of the present invention with reference to the accompanying drawings.

[0054] Embodiment 1:

[0055] Combined with Figures 1 - 11 As shown, a smart monitoring system for a distribution network provided by the present invention includes a cable temperature control monitoring screen 100, a connector flame retardant mechanism 400 installed inside a transformer connector, a temperature control mechanism 200 installed on the connector flame retardant mechanism 400, two electromagnetic position control mechanisms 300 installed on the connector flame retardant mechanism 400, and a wire loading mechanism 500 installed inside the connector flame retardant mechanism 400.

[0056] The temperature control mechanism 200 includes an external wire 210, a controller 220, a temperature measuring head 230, an adapter chassis 240, an electromagnetic adapter cable 250, a motor 260, a bellows 270, a reducer chassis 280 and an exhaust blade shaft 290. The electromagnetic positioning mechanism 300 includes a clamp 310, a protective shell 320, a magnetic column 330, a coil 340, a coil connector 350 and a permanent magnetic guide rod 360. The joint flame retardant mechanism 400 includes a first protective cover 410, a second protective cover 420, a combination bolt 430, a conductive sheet 440, a drainage assembly 450, a compression spring 460, a fuse 470 and an insulating sealing chamber 480, and the drainage assembly 450 also includes a conductive connector 451, a wiring guide 452, a compression gasket 453 and a fastening bolt 454. The wiring mechanism 500 includes a transformer output line 510, a protective sleeve 520 and a locking bolt 530.

[0057] The cable temperature control monitoring screen 100 is used to monitor the real-time thermal energy data received by the temperature control mechanism 200 and provide instructions for the operation of the temperature control mechanism 200;

[0058] The temperature control mechanism 200 includes a temperature measuring head 230 for detecting heat energy, a controller 220 connected to the temperature measuring head 230 by a wire, two plug rods are installed on one side of the controller 220, and the outer ends of the two plug rods are connected to a motor 260, and a bellows 270 and an exhaust blade shaft 290 movably installed inside the bellows 270 are installed outside the motor 260;

[0059] The two sets of electromagnetic position control mechanisms 300 are used to provide reset kinetic energy for the components in the joint flame retardant mechanism 400;

[0060] The joint flame retardant mechanism 400 includes a first shield 410 mounted on the controller 220, a second shield 420 disposed outside the first shield 410, a conductive sheet 440 mounted inside the second shield 420, a drainage assembly 450 disposed inside the first shield 410, and a fuse 470 plugged into the conductive sheet 440;

[0061] The wire installation mechanism 500 includes a transformer output wire 510 disposed in the drainage assembly 450, a protective sleeve 520 disposed on the insulation layer of the exposed core wire portion of the transformer output wire 510, and two locking bolts 530 threadedly installed inside the protective sleeve 520;

[0062] A cylindrical rubber pad is installed on one end of the locking bolt 530 that passes through the interior of the protective sleeve 520.

[0063] There are many potential safety hazards in today's power operation system, and the data collection of the power system is not comprehensive enough. The biggest safety hazard in the distribution network is the lack of effective monitoring between the transformer and the output line. With the daily demand for electric energy from users, once the environmental temperature rises, the electricity consumption of residents will also increase. If the tightness of the connection between the transformer joints and each output line by the workers is insufficient, and due to factors such as the ambient temperature around the transformer interfering with the joints and lines, the transformer joints and output lines will fuse due to overheating. In severe cases, the insulation layer of the output line will spontaneously combust, which will then affect the transformer and cause dangerous accidents such as the explosion of the transformer due to open fire.

[0064] When the device is in use, the worker needs to use a screwdriver to loosen the bolts inside the transformer joint, then insert one end of the conductive sheet 440 away from the second shield 420 into the inside of the transformer joint, and tighten the bolts inside the transformer joint. When the conductive sheet 440 is fastened, the conductive sheet 440 and the conductive joint 451 assembled by the first shield 410 and the second shield 420 can be connected by the fuse link 470. At this time, the two combined bolts 430 can provide a stable docking platform for the conductive joint 451. After the two coils 340 are energized and change the magnetic fields of the two magnetic posts 330, the two permanent magnet guide rods 360 movably installed inside the two sets of protective shells 320 will be pressed and extend into the inner cavity of the first shield 410. At this time, the conductive joint 451 will be squeezed by the two permanent magnet guide rods 360. At this time, the fuse link 470 will be pressed tightly by the conductive joint 451 and the conductive sheet 440. The transformer output line 510 installed inside the wiring conduit 452 can be docked with the transformer joint. When the insulation sealing chamber 480 arranged outside the wiring conduit 452 collects the heat energy during the operation of the transformer output line 510, the temperature measuring head 230 can detect the heat energy. Finally, the controller 220 will transfer the temperature measurement data of the temperature measuring head 230 to the cable temperature control monitoring screen 100. The worker can observe the change of the heat energy data displayed in the cable temperature control monitoring screen 100, and then send instructions to each controller 220. The motor 260 started by the controller 220 will drive the input shaft of the reduction gear box 280, and drive the exhaust fan blade shaft 290 through the output shaft. Finally, the air flow generated inside the air box 270 can forcibly cool the inner cavities of the first shield 410 and the second shield 420. Once the fuse link 470 fuses due to an accident, the controller 220 will stop supplying energy to the two coils 340. Finally, the two permanent magnet guide rods 360 that lose the magnetic field effect can drive the conductive joint 451 to contract towards the inner cavity of the first shield 410. At this time, the docking between the transformer joint and the output line can be monitored in real time for temperature control, and the occurrence of transformer fire can be reduced.

[0065] Embodiment 2:

[0066] Combined with Figures 2 - 9As shown in the figure, on the basis of Embodiment 1, the temperature control mechanism 200 further includes a reduction gearbox 280 installed on the top of the air box 270, a transfer chassis 240 installed at the bottom of the controller 220, an external wire 210 connected to the controller 220, and two groups of electromagnetic transfer wires 250 connected to both ends of the bottom of the transfer chassis 240. The bottom of the housing of the reduction gearbox 280 is provided with L-shaped feet, and the L-shaped feet are installed on two screw rods on the top of the air box 270;

[0067] The bottom of the reduction gearbox 280 is respectively provided with an input shaft and an output shaft. The input shaft is connected to the transmission shaft in the motor 260, and the output shaft is connected to the rod body of the exhaust fan blade shaft 290;

[0068] The external wire 210 is connected to the power-on wiring hole reserved by the transformer.

[0069] When the external wire 210 is connected to the power supply, the controller 220 can be in the standby state. The signal sources of each controller 220 and the cable temperature control monitoring screen 100 are docked through the private frequency signal source. At this time, the cable temperature control monitoring screen 100 can monitor each controller 220. When the temperature measuring head 230 is connected to the controller 220 through a wire, the temperature measuring head 230 extending into the inner cavity of the insulating seal chamber 480 measures the heat energy released by the operation of the transformer output wire 510. The controller 220 can monitor the real-time temperature between each transformer output wire 510 and each joint of the transformer. Once the heat energy released by the transformer output wire 510 exceeds the rated value, the instruction set by the cable temperature control monitoring screen 100 will send a signal to the controller 220. Finally, the motor 260 will start. Through the linkage of the reduction gearbox 280, the exhaust fan blade shaft 290 can finally cool the inner cavities of the first shield 410 and the second shield 420 to ensure that the temperature in the working area of the fuse link 470 is regulated in real time.

[0070] Embodiment 3:

[0071] Combined with Figures 3 - 11 As shown in the figure, on the basis of Embodiment 1, the electromagnetic position control mechanism 300 includes a fixture 310 installed outside the insulating seal chamber 480;

[0072] The fixture 310 is composed of a bracket and two loop buckles. Two protective shells 320 are installed inside the two loop buckles, a permanent magnet guide rod 360 movably installed in the two protective shells 320, a magnetic column 330 installed in the inner cavities of the two protective shells 320, and a coil 340 wound around the magnetic column 330;

[0073] The two exposed wire ends of the coil 340 respectively penetrate into the interiors of the two protective shells 320;

[0074] At the top of each of the two protective housings 320, a coil connector 350 is installed, and the two exposed wire ends are respectively connected to the two coil connectors 350;

[0075] Inside the coil connector 350, a connection hole is provided. The wire end of the electromagnetic transfer wire 250 far from the transfer chassis 240 is adaptively penetrated into the connection hole inside the coil connector 350 and is used to supply energy to the coil 340.

[0076] Using bolts, the two clamps 310 are respectively fixedly installed outside the insulating sealed chamber 480. At this time, the two groups of protective housings 320 fixed by the two clamps 310 can provide a stable platform for the extension of the two permanent magnet guide rods 360. With the two groups of electromagnetic transfer wires 250 respectively connected to the four coil connectors 350, the two energized coils 340 can change the magnetic field of the magnetic column 330. At this time, the two permanent magnet guide rods 360 can be pushed outward by the magnetic column 330, and the two permanent magnet guide rods 360 can push the conductive connector 451 towards the conductive sheet 440. Finally, the fuse link 470 can be pressed tightly, and one end of the pressed fuse link 470 can be attached to the end of the wiring conduit 452 penetrating into the inner cavity of the conductive connector 451, so that the transformer output wire 510, the wiring conduit 452, the fuse link 470, and the conductive sheet 440 are in a connected state. Once the fuse link 470 is blown, the two powered-off coils 340 can restore the magnetic field state of the magnetic column 330. Finally, the two permanent magnet guide rods 360 can be attracted, and the conductive connector 451 will contract into the inner cavity of the first shield 410 under the action of the two permanent magnet guide rods 360 and the two compression springs 460. At this time, the wiring conduit 452 can keep a safe power-off state with the conductive sheet 440, thus avoiding the problem that the transformer is ignited due to excessive load and self-ignition of the transformer output wire 510.

[0077] Example 4:

[0078] Combined with Figures 2 - 11 As shown, in the above embodiment, the joint flame retardant mechanism 400 further includes two groups of combined bolts 430 installed inside the first shield 410 and the second shield 420;

[0079] A nut for pressing the first shield 410 is connected to the threaded section of the combined bolt 430, and a compression spring 460 is arranged outside the combined bolt 430;

[0080] The drainage assembly 450 includes a conductive connector 451 movably installed on the rod body of the combined bolt 430, a wiring conduit 452 installed inside the conductive connector 451, two pressing gaskets 453 installed in two sliding grooves on the inner wall of the wiring conduit 452, and two fastening bolts 454 installed in two screw holes of the wiring conduit 452;

[0081] An insulating and sealing chamber 480 is installed at the outer end of the conductive joint 451, and the insulating and sealing chamber 480 is arranged outside the wiring conduit 452;

[0082] Both sides of the insulating and sealing chamber 480 are provided with hollow holes, and two fastening bolts 454 are located in the two hollow holes;

[0083] Both the first shield 410 and the second shield 420 are made of thickened insulating plastic, and ventilation slots are provided inside the first shield 410 and the second shield 420;

[0084] An exhaust slot is provided at the bottom of the bellows 270, and the exhaust slot communicates with the ventilation slots inside the first shield 410 and the second shield 420.

[0085] The insulating and sealing chamber 480 is used to collect the heat energy released by the wiring conduit 452. When the end of the temperature measuring head 230 is inserted into the inner cavity of the insulating and sealing chamber 480, the heat energy collected by the insulating and sealing chamber 480 can be immediately measured by the temperature measuring head 230, and the measured heat energy value will be transferred to the cable temperature control monitoring screen 100 through the controller 220. Workers can observe the various transferred heat energy values on the screen of the cable temperature control monitoring screen 100. For the different high temperatures borne by the transformer under different seasonal loads, the obtained selectable controllers 220 can selectively adjust the rated values of the heat energy of each controller 220, so as to accurately detect the multiple transformer output lines 510 in real time. At the same time, the set fuse 470 can reduce the loss of replacing the transformer output line 510 and the transformer joint, and improve the maintenance speed and efficiency of the transformer and the output line by workers.

[0086] The working principle and usage process of the present invention: Workers need to use a screwdriver to loosen the bolts inside the transformer joint, then insert one end of the conductive sheet 440 with an arc structure into the inside of the transformer joint, then tighten the bolts inside the transformer joint, then loosen the two fastening bolts 454 counterclockwise, then insert the bare core wire at one end of the transformer output line 510 along the inner cavity of the wiring conduit 452, and then tighten the two fastening bolts 454 clockwise until the core wire is tightly pressed and fixed by the two pressing gaskets 453. At this time, the insulating and sealing chamber 480 installed outside the wiring conduit 452 can collect the temperature released by the operation of the core wire of the transformer output line 510 and the wiring conduit 452. The temperature measuring head 230 connected to the controller 220 through a wire, and the probe is inserted into the end pipe at the top of the insulating and sealing chamber 480, and the probe extends into the inner cavity of the insulating and sealing chamber 480;

[0087] Assemble multiple conductive sheets 440 with the respective connectors of the transformer in sequence according to the above steps. At this time, the two sets of combined bolts 430 can press the superposed first shield 410 and second shield 420 against the outside of the conductive sheet 440 and the conductive connector 451. At this time, the fixed conductive sheet 440 and the conductive connector 451 will be connected by the fuse link 470. When the external wire 210 is connected to the reserved power connector of the transformer, the controller 220 in the energized state, the two pole columns on the side close to the fuse link 470 will be connected to the connector of the motor 260. And the two sets of electromagnetic position control mechanisms 300 connected by the transfer chassis 240 and the two sets of electromagnetic connecting wires 250 will be in the extended state in the energized state. At this time, the permanent magnet guide rods 360 arranged in the inner cavities of the two protective shells 320 will extend into the interior of the first shield 410 under the action of the magnetic field thrust. Finally, the two permanent magnet guide rods 360 can squeeze the conductive connector 451 towards the conductive sheet 440, and the fuse link 470 can be pressed by the conductive connector 451 and the positioned conductive sheet 440;

[0088] When the real-time temperature measurement and monitoring of the device are carried out on each output wire connected to each connector of the transformer, the temperature of each output wire and the transformer connector during operation is monitored through the cable temperature control monitoring screen 100. Once the load of the incoming line is too large, which leads to high temperature at the transformer output wire 510 and the transformer connector part, the cable temperature control monitoring screen 100 sends an electrical signal to the controller 220. The operating controller 220 will then control the motor 260 to operate. At this time, the transmission shaft in the motor 260 will drive the input shaft at the bottom of the reduction gearbox 280, and then the output shaft at the bottom of the reduction gearbox 280 will drive the exhaust fan shaft 290 to rotate at high speed. The high-pressure air flow generated at this time will enter the inner cavities of the first shield 410 and the second shield 420 from the notch at the bottom of the air box 270, and finally can forcibly cool the conductive joint 451, the conductive sheet 440 and the fuse link 470. Once a sudden accident occurs between the line and the transformer, the fuse link 470 can be fused in an instant when the sudden accident occurs. When the controller 220 monitors the instant of the fuse link 470 being fused, it will cut off the power supply to the two coils 340. At this time, the magnetic field in the inner cavities of the two protective shells 320 will change, and then the permanent magnet guide rod 360 will be attracted to the end of the magnetic column 330. At this time, the conductive joint 451 without the extrusion of the two permanent magnet guide rods 360 can be forced to contract towards the inner cavity of the first shield 410. Since one end of the wiring conduit 452 far from the transformer output wire 510 penetrates into the inner cavity of the conductive joint 451, and one end of the fuse link 470 far from the conductive sheet 440 penetrates into the conductive joint 451 and fits with the end of the wiring conduit 452. As the conductive joint 451 and the conductive sheet 440 are separated, the transformer output wire 510 and the wiring conduit 452 will maintain an absolutely safe gap with the conductive sheet 440, thus effectively avoiding serious accidents such as spontaneous combustion of the transformer due to line faults, effectively improving the protection of the transformer, and greatly reducing the protection cost of the transformer output line.

[0089] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
