For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] See also Figures 1 to 7The 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 a plug-in insulating plug 405 and a converter 404, and the insulation The end face of the edge plug 405 faces the opening of the left box door mechanism 200 or the opening of the right box 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 box door mechanism 200 or the right box door mechanism 300 in the power-on state; the locking mechanism 500 can be released from the left box door mechanism 200 or the right box door mechanism 300 in the power-off state; the grounding bar 105 is arranged 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 access to the emergency power supply vehicle for power supply, improving the on-site operation efficiency of emergency power supply and reducing power outage time.

[0025] The left door mechanism 200 and the right door mechanism 300 are hinged to the openings on both sides of the box body 100, which enables the operator to disassemble and repair the internal components of the quick-connect emergency power distribution device at the openings on both sides, thereby improving the convenience of the operation. On the other hand, the internal components of the quick-connect emergency power distribution device are isolated from the outside, achieving the purpose of full sealing, and effectively ensuring the personal safety of the operator.

[0026] The input side of the insulating mechanism 400 is used to connect the external plug 800, which is connected to the input side cable; the output side of the insulating mechanism 400 is connected to the user end through the cable 700, which is the output side cable. The insulating plug 405 and the converter 404 are plugged in, and the insulating plug 405 can play an insulating effect and improve the safety of the operation; after removing the insulating plug 405, the external plug 800 can be quickly plugged in with the converter 404, which optimizes the space occupied by the wire nose compared to the traditional connection method of the wire nose and reduces the volume and weight of the quick-connect emergency power distribution device; the converter 404 adds a quick interface, which greatly reduces the time for the external plug 800 to connect to the device, realizes rapid power supply, greatly improves the wiring efficiency, shortens the wiring hours and the power outage time at the user end. In addition, the grounding bar 105 is grounded after being electrically connected to the insulating plug 405, which further improves the insulation performance of the insulating plug 405, effectively preventing operators from accidentally getting electric shock when repairing the quick-connect emergency power distribution device. The insulating mechanism 400 adopts a fully insulating design, and the insulating plug 405 is a silicone rubber cable connector that can be touched when powered. The inside of the insulating plug 405 is a semi-conductive shielding layer, and the outside 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 in size and heavy in weight. The present application adopts a fully insulating design, and the electrical clearance between phases and between phases to the ground is compact, thereby reducing the size and weight of the quick-connect emergency power distribution device, so that the quick-connect emergency power distribution device can be installed not only on the ground, but also on overhead lines, which improves the flexibility of the installation of the quick-connect emergency power distribution device.

[0027] like Figure 8As shown, in this embodiment, the quick-connect emergency power distribution device corresponds to the connection with 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 on-board high-voltage cable (i.e., the input side cable) is connected to the converter 404 on the input side of the device through the external plug 800 of the high-voltage power supply vehicle, and the power supply 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 the device, and then transmitted to the user end through the cable 700, so that the user end can be quickly powered by the quick-connect emergency power distribution device under the condition that the 10kV overhead line is powered off, 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.

[0028] The quick-connect emergency power distribution device also includes an interlocking mechanism 600, which is used to prevent the converter 404 of the device from being directly powered due to the lack of an insulating plug 405 when the device is in a non-emergency power supply state, thereby increasing the safety of the device. Only when all converters 404 of the device are fully installed with insulating plugs 405, the interlocking mechanism 600 is unlocked, and the left box door mechanism 200 can be closed with the box body 100, thereby achieving an error-proofing effect and ensuring that all insulating plugs 405 have been installed when the left box door mechanism 200 is closed.

[0029] The locking mechanism 500 is used to lock or unlock the door mechanism, that is, the left door mechanism 200 or the right door mechanism 300. In the abnormal state of emergency power supply, 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 time, the locking mechanism 500 is engaged with the door mechanism, and the door mechanism cannot be opened, which effectively ensures the personal safety of the operator; in the normal state of emergency power supply, 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 time, the locking mechanism 500 is released from the door mechanism, and the operator can open the door mechanism for maintenance and other operations.

[0030] In this embodiment, a pair of ear plates are provided at the top of the box 100, and the pair of ear plates are used to hoist the box 100; the bottom end of the box 100 is installed on the cross arm led out from the electric pole to realize the installation of the quick-connect emergency power distribution device on the overhead line. Shutters are provided on the side panels of the box 100 to improve the heat dissipation performance of the box 100. The cable 700 passes through the bottom plate of the box 100, and a protective coil 102 is provided on the cable 700. The protective coil 102 is connected to the bottom plate of the box 100 to fix and protect the cable 700. The insulating mechanism 400 includes a mounting plate 401, a double-pass sleeve 402, a cable plug 403, a converter 404 and an insulating plug 405; a first mounting frame 103 is provided in the middle position of the box 100, and the mounting plate 401 is installed on the first mounting frame 103, so as to realize the suspended installation of the insulating mechanism 400 in the box 100 and improve its insulation performance; the double-pass sleeve 402 is connected to the fixing hole provided on the mounting plate 401; one end of the double-pass sleeve 402 is connected to the cable plug 403 by bolts, and the other end is connected to the converter 404 by bolts; the cable plug 403 is connected to the cable 700. The converter 404 is plugged with the insulating plug 405 when the device is not working, and is plugged with the external plug 800 when working, which is convenient for plugging and effectively improves the insulation efficiency and wiring efficiency of the converter 404. A material storage area is provided inside the box 100, and the insulating plug 405 can be placed in the material storage area when not in use. Optionally, the insulating plug 405 is snap-fitted to the material storage area, ready for use, and can have a fool-proof effect, reminding the operator whether the insulating plug 405 is missed before closing the box door mechanism.

[0031] See also Figures 9 to 13The left door mechanism 200 and the right door mechanism 300 both include a door panel 201, a hinge 202, a door lock 204 and a latch piece 205; the door panel 201 is hingedly connected to the box body 100 through 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 taking device 502 and a correspondingly arranged on the inner wall of the box body 100. The charged indicator 501 and the electromagnetic plug 503; the capacitive coupling power taking device 502 is sleeved on the cable 700; the capacitive coupling power taking device 502 and the charged indicator 501 are electrically connected to the electromagnetic plug 503 correspondingly; when the capacitive coupling power taking device 502 and the charged indicator 501 are both powered, the electromagnetic plug 503 is engaged with the plug piece 205; when the capacitive coupling power taking device 502 or the charged indicator 501 loses power, the electromagnetic plug 503 and the plug piece 205 are released from engagement. In this embodiment, the capacitive coupling power taking device 502 is sleeved on the cable 700, the charged indicator 501 is mounted on the second mounting frame 104 of the box 100, and a pair of electromagnetic plugs 503 are mounted one by one on the inner wall of the box 100 near the openings on both sides, so that the electromagnetic plug 503 and the plug piece 205 cooperate to limit. Specifically, the door lock 204 is used to lock or unlock the connection between the door panel 201 and the box 100. The latch plate 205 is provided with a through hole, and the latch of the electromagnetic latch 503 can be inserted into or withdrawn from the through hole, so as to correspondingly realize the locking or unlocking of the locking mechanism 500 and the door mechanism. Only when the electromagnetic latch 503 loses power, the latch of the electromagnetic latch 503 will withdraw from the through hole, and at this time, the door lock 204 can be unlocked to open the door panel 201, thereby preventing the operator from opening the door mechanism when the quick-connect emergency power distribution device is powered on, thereby avoiding accidental electric shock.

[0032] Furthermore, the left door mechanism 200 also includes a door limit 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 hinged to the middle of the left opening of the box body 100; one end of the door limit cable 203 is buckled to the box body 100, and the other end is buckled to 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 when disassembling and repairing components. The stretching length of the door limit cable 203 is fixed, see again Figure 7When the left door mechanism 200 is fully opened, the door limit cable 203 is tightened, and the door limit cable 203, the door panel 201 and the box body 100 form a triangular structure with high connection strength. The door limit cable 203 is used to hook the door panel 201 from above, and the door panel 201 can be automatically positioned after opening by using its own weight, which prevents the operator from shaking the door panel 201 during the wiring process and affecting the work efficiency. In addition, the hinge 202 is set in the middle of the left opening of the box body 100. Compared with the connection method of setting the hinge 202 on the bottom plate of the box body 100, the hinge 202 is located in the middle of the opening, which can effectively reduce the volume of the door panel 201. With the suspension installation method of the insulation mechanism 400 in the box body 100, it is convenient for the operator to work at the opening of the left door mechanism 200.

[0033] Secondly, when the left door mechanism 200 is fully opened, the top height of the door panel 201 is lower than the axis height of the converter 404, so that the input side cable of the external plug 800 plugged with the converter 404 can abut against the top of the door panel 201. The weight of the cable is heavy. When the input side cable is arranged horizontally, a certain bending will occur at the junction of the input side cable and the external plug 800. The device supports the input side cable through the top of the door panel 201, which can reduce the bending arc at the junction of the input side 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 the inner walls of the door panel 201 and the box body 100, and buckles are provided at both ends of the door limit steel cable 203. The buckles are buckled with the welding ring 106. The buckled connection mode facilitates the disassembly and assembly of the door limit steel cable 203. By replacing the door limit steel cable 203 of different lengths, the door panel 201 can be opened to the corresponding opening and closing angle, thereby supporting input side cables of different outer diameters.

[0034] In addition, the capacitive coupling power taking device 502 is connected to the inner wall of the box 100. The capacitive coupling power taking device 502 is set on the cable 700 through its winding, which is used to couple and provide energy for the electromagnetic plug 503 to operate, thereby protecting the electrical equipment. At the same time, the winding is fixed to the inner wall of the box 100, which plays the role of a line clamp, simplifies the fixing structure of the cable 700, and the capacitive coupling power taking device 502 cooperates with the protective coil 102, effectively improving the connection strength between the cable 700 and the box 100, and improving the adaptability of the quick-connect emergency power distribution device to be installed on the overhead line.

[0035] like Figures 14 to 18As 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 limit rod 603, an L-shaped limit plate 604, a slider 605 and a rotating rod 606; one end of the door limit rod 603 is slidably connected to the left box door mechanism 200 along the X axis, and the other end is rotatably connected to the slider 605 around the Y axis; the first end of the L-shaped limit plate 604 and the baffle 602 are correspondingly sleeved on the door limit rod 603, and the two ends of the first spring 601 are connected to the first end of the L-shaped limit plate 604 and the baffle 602 one by one; the second end of the L-shaped limit plate 604 is connected to the inner wall of the box body 100; the slider 605 is provided with a The first end of the rotating rod 606 is slidably connected to the guide groove along the axial direction of the guiding groove; the rotating rod 606 is connected to the inner wall of the box body 100 for rotation around the Y axis; when the insulating plug 405 is installed, the end face of the insulating plug 405 abuts against the free end of the rotating rod 606, and the end of the door stopper rod 603 is located inside the wall of the box body 100; when the insulating plug 405 is not installed, the free end of the rotating rod 606 abuts against the converter 404 or the baffle 602 abuts against 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 box door mechanism 200 to limit the closing of the left box door mechanism 200. Among them, 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 plate of the box body 100.

[0036] In this embodiment, the door stop rod 603 is connected to the slider 605 by a locking screw 607 for rotation around the Y axis; the rotating rod 606 is connected to the axial screw 609 for rotation around the Y axis, and the axial screw 609 is connected to the positioning rod 608 welded on the box body 100. The first spring 601, the baffle 602 and the L-shaped stop plate 604 are combined to form an elastic reset component of the door stop rod 603. Fig.16 , the insulating plug 405 is normally plugged into the converter 404, 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 axial 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. Fig.17 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 a 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.

[0037] Furthermore, the rotating rod 606 is a V-shaped rod; the V-shaped rod can be in line-surface contact with the insulating plug 405. Compared with the point-surface contact between the rotating rod 606 and the insulating plug 405, the line-surface contact between the V-shaped rod and the insulating plug 405 is more stable, improves the retraction accuracy of the door stopper rod 603, effectively avoids the situation where the left door mechanism 200 cannot be closed due to insufficient retraction of the door stopper rod 603, and improves the reliability of the interlocking mechanism 600.

[0038] like Fig.19 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 along the axial direction of 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 being separated from the shell 611. See again Fig.17 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. Fig.16 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 .

[0039] 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 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 in which 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 normally installed, thereby reducing the thickness of the wall of the box body 100 and reducing the weight of the quick-connect emergency power distribution device.

[0040] like Figures 18 to 20As shown, the interlocking mechanism 600 further includes an insulating connecting plate 613; the housing 611 is connected to a 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, a slot is provided on the insulating connecting plate 613, the housing 611 is embedded in the slot, and the insulating connecting plate 613 is fixed to the rotating rod 606 by a pin 614. The insulating connecting plate 613 can play an insulating role, preventing current from being conducted between the converter 404 and the interlocking mechanism 600, and further ensuring the safety of the operation.

[0041] In addition, the plurality of insulating plugs 405 are plugged with the plurality of converters 404 in a one-to-one correspondence; the insulating connecting plate 613 is arranged at the center line position of the plurality of converters 404 arranged in a wave shape along the Y axis; and the plurality of top covers 612 are abutted with the plurality of insulating plugs 405 in a one-to-one correspondence. Specifically, the insulating connecting plate 613 is arranged at the center line position of the plurality of converters 404, so that the top cover 612 arranged thereon can abut with the top end or the bottom end of the insulating plug 405 in a corresponding manner, thereby reducing the volume and weight of the insulating connecting plate 613, and at the same time, the insulating connecting plate 613 does not affect the plugging of the external plug 800 with 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 missing after the operator closes the left box door mechanism 200.

[0042] In one embodiment: After the upper input side switch is turned off, the capacitor coupling power taking device 502 and the charged display 501 lose power, the bolt of the electromagnetic bolt 503 retracts, and the left box door mechanism 200 and the right box door mechanism 300 can be opened through the door lock 204; In the power protection scenario, the high-voltage power supply vehicle arrives at the scene, and the vehicle-mounted high-voltage cable is plugged into the converter 404 of the device through the emergency input side external plug 800; Start the power supply of the high-voltage power supply vehicle, and the power of the high-voltage power supply vehicle is transmitted to the cable plug 403 on the output side of the device, and then transmitted to the cable 700; at this time, the input side is powered by the power supply vehicle, which plays an emergency role after power outage and reduces the power outage time; After the power protection is completed, turn off the power of the high-voltage power supply vehicle, 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, and the end of the door limit rod 603 is stuck between the sliding hole of the left door panel mechanism 200 and 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 limit rod 603 retracts a certain distance; when all three insulating plugs 405 are installed, the door limit 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 box door mechanism 200 can be closed normally; if any insulating plug 405 is not installed or missed during operation, the door limit rod 603 will not be able to close the left box door mechanism 200 due to insufficient retraction distance; after installing 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 is now restored to the upper input side power supply; After the switch on the upper input side is closed, the 10kV fully enclosed and fully insulated quick-connect emergency power distribution device is energized, and the left door mechanism 200 and the right 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 door mechanism 200 and the right door mechanism 300 are normally closed, and the door panel 201 cannot be opened from the outside.
