In power systems, electrical complete sets of equipment mainly undertake the tasks of power transmission and distribution. They can be used to protect power systems from electrical faults such as overload, short circuit, ground fault, etc., and can also be used to achieve remote control and automation of power systems.

[0003] After searching, it is found that there are problems with the electrical complete switchgear in the prior art. There are many lines connected to the electrical equipment in the cabinet.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In a typical implementation of this application, please refer to Figures 1 to 9 , an electrical switchgear for a power distribution system, comprising a cabinet 1, a cabinet door 2 is rotatably connected to one side of the cabinet 1 through a hinge, a mounting frame 3 is fixedly mounted on the top surface of the cabinet 1, a filter screen 4 for filtering dust is fixedly mounted on the top surface of the mounting frame 3, the filter screen 4 can filter dust in the air to reduce dust entering the cabinet 1, and a plurality of support seats 15 are slidably connected to the inside of the cabinet 1 for supporting electrical equipment and lines;

[0030] The movable plate 9 is slidably connected to the inside of the cabinet 1, and is used to drive the support seat 15 to move. The quick maintenance mechanism 7 is arranged inside the cabinet 1, and is used to quickly repair the circuit inside the cabinet 1. The quick maintenance mechanism 7 includes a plurality of Rogowski coils 42, and the plurality of Rogowski coils 42 are respectively fixedly installed on one side of the plurality of support seats 15, and an integrator 43 cooperating with the Rogowski coils 42 is fixedly installed on one side of the support seat 15;

[0031] According to Ohm's law, the current I can be calculated from the voltage V and the resistance R: I = V / R. The line resistance is fixed. Through this formula, the normal threshold range of the current in the line is determined;

[0032] When the line passes through the Rogowski coil 42, due to the change of the current in the line, the Rogowski coil 42 will induce a voltage, and this induced voltage is proportional to the rate of change of the current in the line, thereby generating a voltage signal proportional to the rate of change of the current. The voltage signal induced by the Rogowski coil 42 is then processed by the integrator 43 to achieve accurate measurement of the current in the line.

[0033] An infrared thermometer 44 is fixedly installed on one side of the support base 15, and the infrared thermometer 44 can measure the temperature of the circuit. A plurality of alarms 5 are fixedly installed on one side of the cabinet door 2, and the alarms 5 correspond to the Rogowski coils 42.

[0034] The current size in the circuit is obtained through the Rogowski coil 42 and the integrator 43, and the surface temperature of the circuit is measured by the infrared thermometer 44, and a comprehensive judgment is made to determine whether the circuit is damaged. When the detection results of the Rogowski coil 42 and the integrator 43 exceed the set threshold range, the alarm 5 corresponding to the Rogowski coil 42 and the integrator 43 that detect this result will sound an alarm to alert the staff;

[0035] Two mounting seats 61 are fixedly installed on the inner bottom surface of the cabinet 1, and the interior of the mounting seat 61 is rotatably connected to a synchronous wheel 16 through a bearing, and the outer circumferential wall of the two synchronous wheels 16 is rotatably connected to a synchronous belt 17, and a driving motor 18 for driving the synchronous wheels 16 to rotate is installed on one side of the support seat 15, and one end of the driving shaft of the driving motor 18 passes through one side of the left mounting seat 61 and is fixedly connected to one end of the synchronous wheel 16;

[0036] In addition, the driving motor 18 drives the synchronous wheel 16 to rotate, and the synchronous wheel 16 rotates to drive the movable plate 9 to move through the synchronous belt 17. The movement of the movable plate 9 will drive the support seat 15 to move outward. After the support seat 15 moves outward, the staff does not need to put their hands into the cabinet 1 to repair the line and electrical equipment, which has a larger operating space and improves the maintenance speed.

[0037] A support frame 8 is fixedly installed on the bottom surface of the support seat 15, and a slide rail 3 48 is slidably connected inside the support frame 8. An electric cylinder 47 for driving the slide rail 3 48 to move is fixedly installed on the top surface of the support frame 8. The bottom surface of the telescopic shaft of the electric cylinder 47 is fixedly connected to the top surface of the slide rail 3 48. Two sliders 3 49 are slidably connected to the bottom surface of the slide rail 3 48. Two mounting blocks 50 are fixedly installed on the bottom surface of the slider 3 49. A connecting rod 1 51 is rotatably connected between the two mounting blocks 50 through a rotating shaft. Two positioning blocks 52 are fixedly installed on both sides of the interior of the support frame 8. One end of the connecting rod 1 51 is connected to the two positioning blocks through a rotating shaft. 52 is rotatably connected, a plurality of clamping columns 56 are fixedly installed on the top surface of the movable plate 9, the clamping columns 56 correspond to the support seat 15, a plurality of semi-cylindrical grooves are opened on the outer circumferential wall surface of the clamping columns 56, and two clamping plates 55 are arranged inside the support frame 8, the clamping plates 55 are arc-shaped and have a plurality of semi-cylindrical protrusions on the inner circumferential wall surface, the inner circumferential wall surface of the clamping plates 55 is movably clamped with the outer circumferential wall surface of the clamping columns 56, a base block 54 is fixedly installed on the outer circumferential wall surface of the clamping plates 55, both sides of the base block 54 are rotatably connected with the second connecting rod 53 through the rotating shaft, and one end of the second connecting rod 53 is rotatably connected with one side of the connecting rod 1 51 through the rotating shaft;

[0038] In the above features, when a line on a certain support seat 15 is damaged, the electric cylinder 47 moves to drive the slide rail 3 48 to move downward, and the slide rail 3 48 moves downward so that the slider 3 49 drives the connecting rod 1 51 to rotate inward, and the connecting rod 1 51 rotates inward to drive the connecting rod 2 53 to move inward, and the connecting rod 2 53 moves inward to drive the clamping plate 55 to clamp with the clamping column 56. At this time, the corresponding support seat 15 is connected with the movable plate 9. Subsequently, when the synchronous belt 17 drives the movable plate 9 to move outward, the support seat 15 with the damaged line thereon and the corresponding electrical equipment will also move outward, which is helpful to accurately know which line and electrical equipment are damaged.

[0039] Support holes 58 for supporting the movement of the slide rail 3 48 are provided on both sides of the support frame 8. Movable blocks 59 are fixedly installed on both sides of the slide rail 3 48. The movable blocks 59 are slidably connected to the support holes 58. The support holes 58 and the movable blocks 59 cooperate to limit the movement of the slide rail 3 48.

[0040] Support tubes 57 are fixedly installed on both sides of the support frame 8. The support tube 57 is slidably connected to a second limit bar 60. One side of the second limit bar 60 is fixedly connected to one side of the base block 54. A T-shaped groove is provided on one side of the support tube 57. The second limit bar 60 is also T-shaped. The two cooperate with each other to limit the movement of the clamping plate 55 to prevent the clamping plate 55 from being misplaced.

[0041] A PLC controller is fixedly installed on one side of the cabinet door 2, and the alarm 5, the drive motor 18, the Rogowski coil 42, the integrator 43 and the infrared thermometer 44 are all electrically connected to the PLC controller;

[0042] With the above technical features, through the cabinet 1, the staff can adjust the electrical equipment power distribution system on the support seat 15 inside the cabinet 1 during use, and the lines on the multiple support seats 15 may be short-circuited and damaged during use;

[0043] The normal threshold range of the current in the circuit is obtained by calculation. At the same time, a safe threshold range needs to be set for the temperature of the circuit. The Rogowski coil 42 and the integrator 43 on the support seat 15 can know the magnitude of the current in the circuit. If the current in the circuit on a certain support seat 15 exceeds the threshold range and the temperature detected by the infrared thermometer 44 is also greater than the threshold, the PLC controller will start the electric cylinder 47 inside the support frame 8 on the bottom surface of the support seat 15. The telescopic shaft of the electric cylinder 47 moves downward to drive the slide rail 3 48 to move downward. The downward movement of the slide rail 3 48 drives the movable block 59 to move inside the support hole 58 on the side of the support frame 8. The support hole 58 and the movable block 59 can cooperate to limit the movement of the slide rail 3 48.

[0044] The downward movement of the slide rail 3 48 also causes the slider 3 49 to move inward on the slide rail 3 48. The inward movement of the slider 3 49 causes the connecting rod 1 51 to rotate inward around the positioning block 52 through the mounting block 50. The inward rotation of the connecting rod 1 51 causes the connecting rod 2 53 to rotate inward. The inward rotation of the connecting rod 2 53 causes the base block 54 and the clamping plate 55 to move inward. The inward movement of the base block 54 causes the limit strip 2 60 to move inside the support tube 57. The support tube 57 and the limit strip 2 60 cooperate to limit the movement of the clamping plate 55 to prevent the two clamping plates 55 from being misaligned. The two clamping plates 55 move inward and clamp with the corresponding clamping columns 56 on the movable plate 9. At this time, the support seat 15 with the damaged circuit is connected to the movable plate 9, while the remaining support seat 15 is not connected to the movable plate 9. At the same time, the alarm 5 corresponding to this support seat 15 will sound an alarm to alert the staff.

[0045] In addition, if the current in the circuit measured by the Rogowski coil 42 and the integrator 43 is greater than the threshold range, the electric cylinder 47 will be used to drive the clamping plate 55 to clamp with the corresponding clamping column 56 even if the temperature detected by the infrared thermometer 44 is within the normal threshold range; this phenomenon may be due to the good heat dissipation effect inside the cabinet 1, resulting in the current increase. The temperature may not rise significantly;

[0046] Accordingly, if the infrared thermometer 44 detects that the temperature of a circuit on a certain support seat 15 exceeds the threshold, even if the Rogowski coil 42 and the integrator 43 detect that the current in the circuit is within the normal range, the electric cylinder 47 inside the support frame 8 corresponding to the support seat 15 will drive the base block 54 to clamp the corresponding clamping column 56. This phenomenon may be due to thermal breakdown.

[0047] On the other hand, when any set of the clamping plates 55 and the clamping columns 56 are clamped together, the support seat 15 with the damaged circuit is connected to the movable plate 9, and the PLC controller starts the driving motor 18, and the driving shaft of the driving motor 18 rotates to drive the synchronous wheel 16 to rotate, and the synchronous wheel 16 rotates through the synchronous belt 17 to drive another synchronous wheel 16 to rotate, and the two synchronous wheels 16 rotate through the synchronous belt 17 to drive the movable plate 9 to move outward, and the movable plate 9 moves outward to drive the support seat 15 with the damaged circuit to move outward. After the support seat 15 moves outward, the staff can quickly identify the damaged circuit and electrical equipment. Compared with the prior art, there is no need to identify the circuits one by one. In addition, the support seat 15 and the circuits and electrical equipment thereon move outward, and the staff has more operating space to repair the circuits and electrical equipment, and does not need to put both hands into the cabinet 1 for repair, which is convenient to operate and efficient.

[0048] In this process, the Rogowski coil 42 and the integrator 43 are used to measure the magnitude of the current in the circuit, and the infrared thermometer 44 can measure the temperature of the circuit. Whether the circuit is damaged is determined by combining the current in the circuit and the circuit temperature. In addition, if the circuit has any of the above two situations, it means that the circuit may be damaged and needs to be repaired. The circuit on the support seat 15 is damaged. The two clamping plates 55 under the support seat 15 will be clamped with the clamping column 56, so that the support seat 15 with the damaged circuit is connected to the movable plate 9 and then moved outward by the cooperation of the synchronous wheel 16 and the synchronous belt 17. When the staff is repairing, they can know which circuit and electrical equipment need to be repaired through the position of the support seat 15 and the operating space is larger, so as to achieve the effect of rapid repair of the circuit and electrical equipment inside the cabinet 1, which is helpful for the staff to use the cabinet 1 and the electrical equipment inside to control the power distribution system;

[0049] A slide rail 13 for supporting the sliding of the movable plate 9 is fixedly installed on the inner bottom surface of the cabinet 1, and a slider 14 is fixedly installed on the bottom surface of the movable plate 9. The slider 14 is slidably connected with the slide rail 13. The movement of the movable plate 9 drives the slider 14 to slide along the slide rail 13. The slide rail 13 and the slider 14 support the movement of the movable plate 9.

[0050] Specifically, by setting the movable plate 9, the movement of the movable plate 9 will drive the slider 14 to move along the slide rail 13. The two sets of slide rails 13 and the slider 14 are respectively located on both sides of the movable plate 9, so that the slide rail 13 and the slider 14 can cooperate to support the movement of the movable plate 9, thereby improving the stability of the movable plate 9 when moving.

[0051] A mounting plate 23 is fixedly installed on one side of the support seat 15, and a line entry hole 24 for allowing the line to pass through is opened on one side of the mounting plate 23. A support bar 25 is slidably connected to the bottom surface of the support seat 15. A micro-electric push rod 26 for driving the support bar 25 to move is fixedly installed on the bottom surface of the support seat 15. One end of the telescopic shaft of the micro-electric push rod 26 is fixedly connected to one side of the support bar 25. The micro-electric push rod 26 is electrically connected to the PLC controller. A limiting column 30 for limiting the support bar 25 is fixedly installed on the bottom surface of the support seat 15. The support bar 2 A connecting hole 29 is provided on the top surface of the support seat 15, and the connecting hole 29 is slidably connected to the limiting column 30. The connecting hole 29 and the limiting column 30 cooperate to limit the movement of the support bar 25. Trapezoidal blocks 27 are fixedly installed on both sides of the support bar 25. The bottom surface of the support seat 15 is rotatably connected to a mounting rod 31 through a rotating shaft. One end of the mounting rod 31 is rotatably connected to a roller 2 32 through a rotating shaft. The other end of the mounting rod 31 is rotatably connected to a roller 3 33 for positioning the line through a rotating shaft. The interior of the support bar 25 is rotatably connected to a roller 1 28 through a rotating shaft.

[0052] The staff passes the line through the line entry hole 24 and connects it to the electrical equipment on the support seat 15. The micro electric push rod 26 drives the support bar 25 to move downward. The support bar 25 moves downward and uses the trapezoidal block 27 to make the installation rod 31 and the roller three 33 rotate inward to abut against the outer wall of the line. At this time, the roller one 28 also abuts against the outer wall of the line, thereby positioning the line.

[0053] Specifically, through the cabinet 1, when installing the circuit inside the cabinet 1, the staff will pass the circuit through the wire entry hole 24 on the mounting plate 23 and connect it to the electrical equipment on the support seat 15, and the PLC controller will start the micro electric push rod 26. The telescopic shaft of the micro electric push rod 26 moves outward to drive the support bar 25 to move outward. The outward movement of the support bar 25 will move outward along the limit column 30. The connection hole 29 and the limit column 30 can cooperate to limit the movement of the support bar 25. The outward movement of the support bar 25 will drive The trapezoidal block 27 moves outward, and the outward movement of the trapezoidal block 27 causes the roller 2 32 on the mounting rod 31 to roll along the inclined surface of the trapezoidal block 27. The roller 2 32 on the mounting rod 31 rolls along the inclined surface of the trapezoidal block 27, causing the other end of the mounting rod 31 to rotate inward. The inward rotation of the other end of the mounting rod 31 drives the roller 3 33 to abut against the outer wall of the line. At this time, the roller 1 28 on the support bar 25 also abuts against the outer wall of the line. The roller 1 28 and the roller 3 33 can position the line to avoid the entanglement of the lines and affect the resolution.

[0054] As a preferred implementation in this embodiment, please refer to Figure 1 to Figure 7The top surface of the cabinet 1 is provided with an air inlet 19, and an air inlet fan 20 for air intake is rotatably connected inside the air inlet 19. Two exhaust holes 11 are provided on the inner bottom surface of the cabinet 1, and an exhaust fan 12 for exhaust is rotatably connected inside the exhaust hole 11. The exhaust fan 12 and the air inlet fan 20 are both electrically connected to the PLC controller. The air inlet fan 20 rotates to allow the outside to enter the inside of the cabinet 1 through the air inlet 19. The two exhaust fans 12 rotate to exhaust the air inside the cabinet 1 and take away the heat inside the cabinet 1;

[0055] Specifically, the cabinet 1 is provided, and the electrical equipment inside the cabinet 1 generates heat during use. The air intake fan 20 rotates so that the external air enters the cabinet 1 through the air intake hole 19. At the same time, the exhaust fan 12 rotates so that the air inside the cabinet 1 is discharged through the exhaust hole 11, which takes away the heat inside the cabinet 1, reduces the temperature inside the cabinet 1, and achieves the heat dissipation effect of the cabinet 1.

[0056] A second slide rail 22 for supporting the sliding of the support seat 15 is fixedly installed on one side of the interior of the cabinet 1, and a crossbeam 21 is fixedly installed inside the cabinet 1.

[0059] When the flame sensor 45 detects flame inside the cabinet 1, the second driving motor 37 drives the screw rod 38 to rotate, the screw rod 38 rotates through the fixed block 39 to drive the rack 36 to move, the rack 36 moves to drive the gear 35 to rotate, the gear 35 rotates to drive the baffle 34 to rotate ninety degrees, and the multiple baffles 34 can close the installation frame 3 at this time, and the air valve 10 will also be closed to prevent external air from entering the interior of the cabinet 1;

[0060] Specifically, through the cabinet 1 that is set, when the equipment inside the cabinet 1 catches fire, the flame sensor 45 detects that a flame appears inside the cabinet 1 and transmits a signal to the PLC controller. After receiving the signal, the PLC controller starts the second drive motor 37. The drive shaft of the second drive motor 37 rotates to drive the screw rod 38 to rotate. The rotation of the screw rod 38 causes the fixed block 39 to move along the screw rod 38. The movement of the fixed block 39 drives the rack 36 to move. The movement of the rack 36 causes multiple gears 35 to rotate. The rotation of the gear 35 causes the baffle 34 to rotate ninety degrees. The baffle 34 rotates ninety degrees to close the installation frame 3. At this time, the PLC controller closes the air valve 10 to isolate the cabinet 1 from the outside air, avoid providing oxygen support for the combustion inside the cabinet 1, extinguish the flame inside the cabinet 1, and avoid affecting other equipment due to the fire of a single cabinet 1.

[0061] A limit strip 40 is fixedly installed between the two bearing seats 6, and a limit hole 41 is provided on one side of the fixed block 39. The limit strip 40 is slidably connected with the limit hole 41. The limit strip 40 and the limit hole 41 cooperate to limit the movement of the fixed block 39;

[0063] Working principle: through the cabinet 1, the circuit inside the cabinet 1 may be damaged after long-term use. The current in the circuit is obtained through the Rogowski coil 42 and the integrator 43, and the surface temperature of the circuit is measured by the infrared thermometer 44. It is comprehensively judged whether the circuit is damaged. When the detection results of the Rogowski coil 42 and the integrator 43 exceed the set threshold range, the alarm 5 corresponding to the Rogowski coil 42 and the integrator 43 that detect this result will sound an alarm to alert the staff;

[0064] Secondly, when a line on a certain support seat 15 is damaged, the electric cylinder 47 moves to drive the slide rail 3 48 to move downward, and the slide rail 3 48 moves downward so that the slider 3 49 drives the connecting rod 1 51 to rotate inward, and the connecting rod 1 51 rotates inward to drive the connecting rod 2 53 to move inward, and the connecting rod 2 53 moves inward to drive the clamping plate 55 to clamp with the clamping column 56. At this time, the corresponding support seat 15 is connected with the movable plate 9. Subsequently, during the process of the synchronous belt 17 driving the movable plate 9 to move outward, the support seat 15 with the damaged line and the corresponding electrical equipment thereon will also move outward, which helps to accurately know which line and electrical equipment are damaged and increases the operating space for repairing the line and electrical equipment. There is no need to put both hands into the cabinet 1 for repair, which is convenient to operate and efficient.

[0065] At the same time, the staff passes the line through the line inlet hole 24 and connects it to the electrical equipment on the support seat 15. The micro electric push rod 26 drives the support bar 25 to move downward. The support bar 25 moves downward and uses the trapezoidal block 27 to make the installation rod 31 and the roller three 33 rotate inward to abut against the outer wall of the line. At this time, the roller one 28 also abuts against the outer wall of the line, thereby positioning the line;

[0066] In addition, the air intake fan 20 rotates to allow the outside to enter the cabinet 1 through the air intake hole 19, and the two exhaust fans 12 rotate to exhaust the air inside the cabinet 1 and take away the heat inside the cabinet 1;

[0067] Finally, when the flame sensor 45 detects flame inside the cabinet 1, the driving motor 2 37 drives the screw rod 38 to rotate, and the rotation of the screw rod 38 drives the rack 36 to move through the fixed block 39. The movement of the rack 36 drives the gear 35 to rotate, and the rotation of the gear 35 drives the baffle 34 to rotate ninety degrees. At this time, multiple baffles 34 can close the installation frame 3, and the air valve 10 will also be closed to prevent external air from entering the interior of the cabinet 1.
