Furthermore, the grounding bar, electrically connected to the insulating plug, further enhances the insulating performance of the plug and effectively prevents accidental electric shock when servicing the quick-connect emergency power distribution unit. The fully insulated design of the insulation mechanism ensures compact phase-to-phase and phase-to-ground electrical clearances, reducing the size and weight of the quick-connect emergency power distribution unit. This allows the unit to be installed not only on the ground but also on overhead lines, enhancing its installation flexibility.

[0042] The locking mechanism is used to lock or unlock the door mechanism. When the internal circuit of the quick-connect emergency power distribution device is turned on, the locking mechanism is energized. At this time, the locking mechanism is engaged with the door mechanism, and the door mechanism cannot be opened, effectively ensuring the personal safety of the operator; when the internal circuit of the quick-connect emergency power distribution device is disconnected, the locking mechanism loses power.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0075] See also Figures 1 to 7 The present invention provides a fully enclosed and fully insulated quick-connect emergency power distribution device, which includes a box body 100, a left box door mechanism 200, a right box door mechanism 300, an insulating mechanism 400, a locking mechanism 500, a cable 700 and a grounding bar 105; the left box door mechanism 200 and the right box door mechanism 300 are hinged to the openings on both sides of the box body 100 to open or close the openings; the insulating mechanism 400 and the locking mechanism 500 are installed inside the box body 100; the input side of the insulating mechanism 400 is provided with an insulating plug 405 and a converter 404, and the insulating plug 405 and the converter 404 are provided with an insulating plug 405 and a converter 404. The end face of the edge plug 405 faces the opening of the left door mechanism 200 or the opening of the right door mechanism 300; the output side of the insulating mechanism 400 is connected to the cable 700, and the cable 700 passes through the box body 100; the locking mechanism 500 is electrically connected to the cable 700; the locking mechanism 500 can be engaged with the left door mechanism 200 or the right door mechanism 300 when powered; the locking mechanism 500 can be disengaged from the left door mechanism 200 or the right door mechanism 300 when powered off; the grounding bar 105 is disposed on the bottom plate of the box body 100 and is electrically connected to the insulating plug 405. The quick-connect emergency power distribution device of the present invention is used for rapid connection with an emergency power supply vehicle for power supply, improving the efficiency of emergency power supply on-site operations and reducing power outage time.

[0076] The left and right door mechanisms 200 and 300 are hinged to the corresponding openings on either side of the housing 100. This allows operators to access and inspect the components within the quick-connect emergency power distribution system, improving operational convenience. Furthermore, it isolates the internal components of the quick-connect emergency power distribution system from the outside, achieving a fully enclosed enclosure and effectively ensuring the operator's safety.

[0077] The input side of the insulation mechanism 400 is connected to an external plug 800, which is connected to the input cable. The output side of the insulation mechanism 400 is connected to the user end via cable 700, which is the output cable. The insulation plug 405 plugs into the converter 404, providing insulation and improving operational safety. After removing the insulation plug 405, the external plug 800 can be quickly connected to the converter 404. Compared to traditional cable lug connections, this optimizes the space occupied by the cable lug and reduces the size and weight of the quick-connect emergency power distribution device. The converter 404 includes a quick connector, which significantly reduces the time it takes to connect the external plug 800 to the device, enabling rapid power supply and significantly improving wiring efficiency, shortening wiring hours and power outage duration at the user end. Furthermore, the grounding bar 105 is grounded after being electrically connected to the insulation plug 405, further improving the insulation performance of the insulation plug 405 and effectively preventing accidental electric shock when operators are servicing the quick-connect emergency power distribution device. The insulating mechanism 400 adopts a fully insulated design, and the insulating plug 405 is a silicone rubber cable connector that can be touched when powered. The interior of the insulating plug 405 is a semi-conductive shielding layer, and the exterior is a conductive shielding layer. It is grounded through the grounding bus 105 to ensure that the surface potential of the insulating plug 405 is the same as the ground. Existing emergency power distribution devices, such as 10kV cable branch boxes, use air insulation inside. Due to the limitation of electrical clearance, the device is large and heavy. The present application adopts a fully insulated design, and the electrical clearances between phases and between phases to ground are compact, thereby reducing the size and weight of the quick-connect emergency power distribution device. In turn, the quick-connect emergency power distribution device can be installed not only on the ground, but also on overhead lines, which improves the installation flexibility of the quick-connect emergency power distribution device.

[0078] like Figure 8As shown, in this embodiment, the quick-connect emergency power distribution device is connected to the 10kV overhead line and the user end, and a drop-out fuse is provided on the circuit between the 10kV overhead line and the quick-connect emergency power distribution device to improve the safety performance of the circuit. Under normal circumstances, that is, in the non-emergency power supply state, the 10kV overhead line supplies power to the user end and the quick-connect emergency power distribution device. Under abnormal circumstances, that is, in the power protection scenario, such as when the 10kV overhead line is disconnected or needs to be repaired, the 10kV overhead line is disconnected from the user end, and the high-voltage power supply vehicle arrives at the scene. The vehicle-mounted high-voltage cable (i.e., the input side cable) is connected to the converter 404 on the input side of this device through the external plug 800 of the high-voltage power supply vehicle, and the power of the high-voltage power supply vehicle is started. The power of the high-voltage power supply vehicle is transmitted to the cable 700 on the output side of this device, and then transmitted to the user end through the cable 700. In the working condition that the 10kV overhead line is out of power, the user end can be quickly powered by the quick-connect emergency power distribution device, thereby reducing the power outage time of the user end. After the power supply is completed, turn off the power of the high-voltage power supply vehicle, unplug the external plug 800 on the emergency input side, plug the insulating plug 405 into the converter 404, close the box door mechanism, and the 10kV overhead line supplies power to the user end.

[0079] The quick-connect emergency power distribution device also includes an interlock mechanism 600, which prevents the equipment from receiving power directly when the device is not in emergency power supply mode due to the lack of insulating plugs 405. This enhances equipment safety. Only when all converters 404 in the equipment are fully installed with insulating plugs 405 does the interlock mechanism 600 unlock, allowing the left door mechanism 200 and the housing 100 to close. This prevents errors and ensures that all insulating plugs 405 are installed when the left door mechanism 200 is closed.

[0080] The locking mechanism 500 is used to lock or unlock the door mechanism, namely, the left door mechanism 200 or the right door mechanism 300. Under abnormal emergency power supply conditions, the cable 700 is connected to the user end, the internal circuit of the quick-connect emergency power distribution device is connected, and the locking mechanism 500 is energized. At this point, the locking mechanism 500 engages with the door mechanism, preventing it from opening, effectively ensuring the operator's personal safety. Under normal emergency power supply conditions, the cable 700 is disconnected from the user end, the internal circuit of the quick-connect emergency power distribution device is disconnected from the user end, and the locking mechanism 500 loses power. At this point, the locking mechanism 500 is disengaged from the door mechanism, allowing the operator to open the door mechanism for maintenance and other operations.

[0081] In this embodiment, a pair of lugs are installed at the top of the box 100 for hoisting the box 100. The bottom of the box 100 is mounted on a crossarm extending from a utility pole, enabling the installation of a quick-connect emergency power distribution device on overhead lines. Louvers are provided on the side panels of the box 100 to improve the heat dissipation performance of the box 100. The cable 700 extends through the bottom panel of the box 100 and is sheathed with a protective coil 102, which is connected to the bottom panel of the box 100 to secure and protect the cable 700. The insulation mechanism 400 includes a mounting plate 401, a two-way bushing 402, a cable plug 403, a converter 404, and an insulating plug 405. A first mounting bracket 103 is provided in the middle of the housing 100. The mounting plate 401 is mounted on the first mounting bracket 103, allowing the insulation mechanism 400 to be suspended within the housing 100 and improving its insulation performance. The two-way bushing 402 is connected to a fixing hole provided in the mounting plate 401. One end of the two-way bushing 402 is bolted to the cable plug 403, and the other end is bolted to the converter 404. The cable plug 403 is connected to the cable 700. The converter 404 plugs into the insulating plug 405 when the device is not in operation and plugs into the external plug 800 when in operation. This facilitates plugging and effectively improves the insulation and wiring efficiency of the converter 404. A material storage area is provided within the housing 100, where the insulating plug 405 can be placed when not in use. Optionally, the insulating plug 405 is snap-fitted to the material storage area, ready for use, and can also play a fool-proof role, reminding the operator whether the insulating plug 405 is missing before closing the box door mechanism.

[0082] See also Figures 9 to 12The left door mechanism 200 and the right door mechanism 300 each include a door panel 201, a hinge 202, a door lock 204, and a latch piece 205; the door panel 201 is hinged to the box body 100 via the hinge 202 to open or close the two side openings of the box body 100; the door panel 201 is sleeved on the door lock 204; the latch piece 205 is arranged on the inner wall of the door panel 201; the locking mechanism 500 includes a capacitive coupling power supply device 502 and a correspondingly arranged on the inner wall of the box body 100. A charge indicator 501 and an electromagnetic latch 503; a capacitive coupling power supply device 502 is mounted on the cable 700; the capacitive coupling power supply device 502 and the charge indicator 501 are electrically connected to the electromagnetic latch 503; when both the capacitive coupling power supply device 502 and the charge indicator 501 are powered, the electromagnetic latch 503 engages with the latch plate 205; when either the capacitive coupling power supply device 502 or the charge indicator 501 loses power, the electromagnetic latch 503 and the latch plate 205 are disengaged. In this embodiment, the capacitive coupling power supply device 502 is mounted on the cable 700, the charge indicator 501 is mounted on the second mounting bracket 104 of the box 100, and a pair of electromagnetic latches 503 are mounted one-to-one on the inner wall of the box 100 near the two side openings to ensure that the electromagnetic latches 503 and the latch plate 205 cooperate to limit the position. Specifically, the door lock 204 is used to lock or unlock the connection between the door panel 201 and the box 100. Latch plate 205 has a through-hole through which the pin of electromagnetic latch 503 can be inserted or removed, correspondingly locking or unlocking the locking mechanism 500 and the door mechanism. Only when electromagnetic latch 503 loses power does it exit the through-hole, unlocking door lock 204 and allowing door panel 201 to be opened. This prevents operators from opening the door mechanism while the quick-connect emergency power distribution device is powered, thereby preventing accidental electric shock.

[0083] Furthermore, the left door mechanism 200 also includes a door-limiting cable 203. On the left door mechanism 200, a hinge 202 is provided at the bottom end of the door panel 201. The hinge 202 is hingedly connected to the middle portion of the left opening of the housing 100. One end of the door-limiting cable 203 is buckled with the housing 100, and the other end is buckled with the inner wall of the door panel 201. The end face of the insulating plug 405 faces the opening of the left door mechanism 200. In this embodiment, the external plug 800 is plugged into the converter 404 through the opening of the left door mechanism 200, and the right door mechanism 300 is only opened for disassembly and maintenance of components. The stretched length of the door-limiting cable 203 is fixed, see again. Figure 7When the left door mechanism 200 is fully opened, the door-limiting cable 203 is tightened, and the door-limiting cable 203, the door panel 201, and the box body 100 form a triangular structure, which has high connection strength. Furthermore, the door-limiting cable 203 hooks the door panel 201 from above, utilizing the deadweight of the door panel 201 to automatically position the door panel 201 after opening. This prevents the operator from shaking the door panel 201 during the wiring process, which could affect work efficiency. Furthermore, the hinge 202 is located in the middle of the left opening of the box body 100. Compared to the connection method where the hinge 202 is located on the bottom plate of the box body 100, the hinge 202 located in the middle of the opening can effectively reduce the size of the door panel 201. Combined with the suspended installation method of the insulating mechanism 400 within the box body 100, it facilitates the operator's work at the opening of the left door mechanism 200.

[0084] Secondly, when the left door mechanism 200 is fully open, the top of the door panel 201 is lower than the axis of the converter 404, allowing the input cable of the external plug 800 connected to the converter 404 to abut against the top of the door panel 201. The cable is heavy, and when the input cable is positioned horizontally, some bending occurs at the junction between the input cable and the external plug 800. This device supports the input cable at the top of the door panel 201, reducing the bending radius at the junction between the input cable and the external plug 800, thereby extending the service life of the external plug 800. In this embodiment, welding rings 106 are provided on both the door panel 201 and the inner wall of the housing 100. Clips are provided at both ends of the door stop cable 203, which snap into place with the welding rings 106. This snap connection facilitates the installation and removal of the door stop cable 203. By replacing the door stop cable 203 with a different length, the door panel 201 can be opened to a corresponding opening and closing angle, thereby supporting input cables of varying outer diameters.

[0085] Furthermore, a capacitive coupling power extraction device 502 is connected to the inner wall of the housing 100. The capacitive coupling power extraction device 502, through its windings, is mounted on the cable 700, coupling and providing energy to activate the electromagnetic plug 503, thereby protecting the electrical equipment. The windings are also secured to the inner wall of the housing 100, acting as a cable clamp and simplifying the securing structure of the cable 700. The capacitive coupling power extraction device 502, in conjunction with the protective coil 102, effectively enhances the connection strength between the cable 700 and the housing 100, improving the adaptability of the quick-connect emergency power distribution device for installation on overhead lines.

[0086] like Figures 13 to 17As shown, the quick-connect emergency power distribution device also includes an interlocking mechanism 600; the interlocking mechanism 600 includes a first spring 601, a baffle 602, a door limiting rod 603, an L-shaped limiting plate 604, a slider 605 and a rotating rod 606; one end of the door limiting rod 603 is connected to the left box door mechanism 200 for sliding along the X axis, and the other end is connected to the slider 605 for rotation around the Y axis; the first end of the L-shaped limiting plate 604 and the baffle 602 are correspondingly sleeved on the door limiting rod 603, and the two ends of the first spring 601 are connected to the first end of the L-shaped limiting plate 604 and the baffle 602 in a one-to-one manner; the second end of the L-shaped limiting plate 604 is connected to the inner wall of the box body 100; the interior of the slider 605 is provided with a The guide groove; the first end of the rotating rod 606 is slidably connected to the guide groove along the axial direction of the guide groove; the rotating rod 606 is rotatably connected to the inner wall of the box body 100 about the Y-axis; when the insulating plug 405 is installed, the end surface of the insulating plug 405 abuts the free end of the rotating rod 606, and the end of the door stopper rod 603 is located within the wall of the box body 100; when the insulating plug 405 is not installed, the free end of the rotating rod 606 abuts the converter 404 or the baffle 602 abuts the inner wall of the box body 100, and the end of the door stopper rod 603 extends out of the wall of the box body 100; the end of the door stopper rod 603 can abut against the left door mechanism 200 to limit the closing of the left door mechanism 200. The X-axis is a direction perpendicular to the opening plane, and the Y-axis is a direction perpendicular to the outer wall of the side panel of the box body 100.

[0087] In this embodiment, the door stop rod 603 and the slider 605 are connected to rotate about the Y axis via a locking screw 607; the rotating rod 606 is connected to the axial screw 609 to rotate about the Y axis, and the axial screw 609 is connected to the positioning rod 608 welded to the box body 100. The first spring 601, the baffle 602 and the L-shaped stop plate 604 form an elastic reset component for the door stop rod 603. Figure 15 The insulating plug 405 is normally plugged into the converter 404, and the insulating plug 405 abuts against the free end of the rotating rod 606, and limits the clockwise swing of the rotating rod 606 around the axis screw 609. In this state, the end of the door limiting rod 603 does not extend out of the wall of the box body 100, and the box door mechanism can be closed. Figure 16 At this time, the insulating plug 405 is not installed on the converter 404, and the baffle 602 is acted upon by the elastic force of the first spring 601, driving the door limit rod 603 and the slider 605 to move to the left. At the same time, the rotating rod 606 swings clockwise around the axial screw 609, and the slider 605 slides on the rotating rod 606 in the direction away from the axial screw 609. The slider 605 rotates clockwise around the locking screw 607, and finally the free end of the rotating rod 606 is pressed against the converter 404. In this state, the end of the door limit rod 603 extends out of the wall of the box body 100, thereby preventing the door panel 201 of the left box door mechanism 200 from closing, reminding the operator that the insulating plug 405 is not installed, thereby ensuring personal safety.

[0088] Furthermore, the rotating rod 606 is a V-shaped rod; the V-shaped rod can abut against the insulating plug 405 in both line and surface. Compared to the point-to-point abutment between the rotating rod 606 and the insulating plug 405, the line-to-surface abutment between the V-shaped rod and the insulating plug 405 is more stable, improving the retraction accuracy of the door stopper rod 603, effectively preventing the left door mechanism 200 from being unable to close due to insufficient retraction of the door stopper rod 603, and improving the reliability of the interlocking mechanism 600.

[0089] like Figure 18 As shown, the interlocking mechanism 600 also includes an elastic pressure block; the elastic pressure block includes a second spring 610, a shell 611 and a top cover 612; the free end of the rotating rod 606 is connected to the shell 611; one end of the second spring 610 is connected to the inner wall of the shell 611, and the other end is connected to the inner wall of the top cover 612; the top cover 612 is connected to the shell 611 in an axially sliding manner along the second spring 610; the top cover 612 can abut against the insulating plug 405. Specifically, the bottom end of the top cover 612, that is, the end located in the shell 611, is provided with a flange, which can abut against the inner wall of the shell 611 to prevent the top cover 612 from separating from the shell 611. See again Figure 16 When the insulating plug 405 is not installed on the converter 404, the first spring 601 pushes the baffle 602 to abut against the inner wall of the box 100, and the rotating rod 606 swings clockwise to the limit position. At this time, the elastic pressure block does not contact other components, and the top cover 612 is pushed out by the second spring 610. Figure 15 When the insulating plug 405 is installed on the converter 404 , the elastic pressing block elastically abuts against the end surface of the insulating plug 405 , and the second spring 610 is compressed and enclosed in the housing 611 together with the top cover 612 .

[0090] Compared with the method in which the free end of the rotating rod 606 directly abuts against the insulating plug 405, this embodiment connects the elastic pressure block to the free end of the rotating rod 606, and the elastic pressure block applies a thrust to the insulating plug 405. The insulating plug 405 can therefore apply a reaction force to the elastic pressure block, and then apply it to the rotating rod 606, the slider 605 and the door limit rod 603, so that the door limit rod 603 retracts, effectively avoiding the situation where the door limit rod 603 is not completely retracted into the wall of the box body 100 due to manufacturing errors and wear errors, and ensuring that the left box door mechanism 200 can be closed normally when the insulating plug 405 is installed normally, thereby reducing the thickness of the wall of the box body 100 and reducing the weight of the quick-connect emergency power distribution device.

[0091] like Figures 17 to 19As shown, the interlock mechanism 600 further includes an insulating connecting plate 613; a housing 611 is connected to the side of the insulating connecting plate 613 facing the converter 404; and the free end of the rotating rod 606 is connected to the side of the insulating connecting plate 613. In this embodiment, the insulating connecting plate 613 has a slot into which the housing 611 fits, and the insulating connecting plate 613 is secured to the rotating rod 606 via a pin 614. The insulating connecting plate 613 provides insulation, preventing current from flowing between the converter 404 and the interlock mechanism 600, further ensuring operational safety.

[0092] Furthermore, the multiple insulating plugs 405 are plugged into the multiple converters 404 in a one-to-one correspondence; the insulating connecting plate 613 is disposed at the centerline of the multiple converters 404 arranged in a wavy pattern along the Y-axis; and the multiple top covers 612 abut against the multiple insulating plugs 405 in a one-to-one correspondence. Specifically, the insulating connecting plate 613 is disposed at the centerline of the multiple converters 404, allowing the top covers 612 disposed thereon to abut against the top or bottom ends of the insulating plugs 405, thereby reducing the volume and weight of the insulating connecting plate 613 and ensuring that the insulating connecting plate 613 does not interfere with the connection between the external plug 800 and the converter 404. In addition, multiple insulating mechanisms 400 are arranged in a wave shape, so that multiple top covers 612 are evenly arranged on the insulating connecting plate 613. The force on the insulating connecting plate 613 is more stable, and the swing sensitivity of the insulating connecting plate 613 is improved. When all the top covers 612 are fully retracted into the shell 611, the door limit rod 603 can be retracted into the wall of the box body 100, and the left box door mechanism 200 can be closed normally, so as to avoid the situation where the insulating plug 405 is not installed after the operator closes the left box door mechanism 200.

[0093] In one embodiment:

[0094] After the upper input side switch is turned off, the capacitor coupling power taking device 502 and the charged display 501 lose power, the electromagnetic latch 503 retracts, and the left door mechanism 200 and the right door mechanism 300 can be opened through the door lock 204;

[0095] In the power protection scenario, the high-voltage power supply vehicle arrives at the scene and connects the vehicle-mounted high-voltage cable to the converter 404 of the device through the emergency input side external plug 800;

[0096] Start the high-voltage power supply vehicle. The power from the high-voltage power supply vehicle is transmitted to the cable plug 403 on the output side of the device, and then to the cable 700. At this time, the input side is powered by the power supply vehicle, which plays an emergency role after the power outage and reduces the power outage time.

[0097] After the power protection is completed, turn off the power of the high-voltage power supply vehicle and unplug the external plug 800 on the emergency input side. At this time, the converter 404 is not installed with the insulating plug 405, and the door limit rod 603 is pushed out under the elastic force of the first spring 601. The end of the door limit rod 603 is stuck between the left box door mechanism 200 and the sliding hole on the wall of the box body 100; when the insulating plug 405 is installed on a converter 404, the top cover 612 is pushed into the shell 611 by the insulating plug 405, so that the insulating connecting plate 613 is forced to drive the rotating rod 606 to rotate around the axial screw 609 at a preset angle, and the door connected to the slider 605 The limiting rod 603 retracts a certain distance; when all three insulating plugs 405 are installed, the door limiting rod 603 retracts to be flush with the outer end surface of the sliding hole of the box body 100 or retracts to the inside of the sliding hole, and the left door panel assembly 200 can be closed normally; if any insulating plug 405 is not installed or missed during operation, the door limiting rod 603 will not be able to close the left box door mechanism 200 due to insufficient retraction distance; after installing the three insulating plugs 405 on the three converters 404 respectively, close the left box door mechanism 200; close the upper input side switch, and the input side will resume power supply to the upper input side;

[0098] After the upper input side switch is closed, the 10kV fully enclosed and fully insulated quick-connect emergency power distribution device is energized, and the left box door mechanism 200 and the right box door mechanism 300 respectively extend the pins of the electromagnetic plug 503 through the capacitive coupling power supply device 502 and the power display 501, and the pins of the electromagnetic plug 503 are inserted into the through holes of the plug plate 205, so that the left box door mechanism 200 and the right box door mechanism 300 are normally closed, and the door panel 201 cannot be opened from the outside.
