[0002] PT cabinet, also known as current transformer cabinet, is a commonly used device in power systems for converting high current into low current for the purpose of measuring, protecting and controlling electrical equipment. PT cabinet usually consists of a large-capacity primary winding and one or more small-capacity primary windings, which are placed in a common housing and connected to a secondary winding and a meter. This secondary winding is usually of low voltage level, such as 10 kV or lower, to reduce interference and errors to the system.

[0003] When inspecting and repairing the equipment, however, since the PT cabinet is usually installed on the ground at a high height and the surrounding environment is relatively complex, it may be necessary to overcome space limitations during maintenance, and when inspecting the PT cabinet, the staff needs to contact high-voltage electrical equipment, which poses certain safety risks. In order to improve safety, the PT trolley is set up. The PT trolley is usually designed for manual operation, and maintenance and repair can be performed without interrupting the operation of the equipment, thereby avoiding personal injury and property loss caused by equipment failure.

DETAILED DESCRIPTION

[0022] The following will be combined with 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.

[0023] like Figures 1 to 12 As shown, the present embodiment proposes an intelligent PT cabinet which is convenient for disassembly and assembly, including a cabinet body 1, wherein the cabinet body 1 includes a busbar room, a trolley room, a control room and a cable room. The cable room is located at the bottom of the cabinet body 1, the trolley room is arranged above the cable room, and the control room is located above the trolley room. A partition 2 is fixedly installed inside the cabinet body 1, one side of the partition 2 is the trolley room, the control room and the cable room, and the other side is the busbar room. A trolley body 3 is arranged in the trolley room, and also includes an intelligent control module 4, a sliding frame 5, a moving component, a positioning component, a control component and an installation component. The intelligent control module 4 is fixedly installed in the control room, the sliding frame 5 is slidably arranged on the upper part of the cable room, and the moving component is installed on the sliding frame 5 for driving the trolley body 3 to move. The moving component includes a slide rail 6 and a roller 7, and the slide rail 6 is fixedly installed on the upper part of the cable room. The slide rail 6 slides with the sliding frame 5, and a plurality of rollers 7 are rotatably installed on both sides of the bottom of the sliding frame 5 at equal distances, and the roller 7 abuts against the top of the cable room.

[0024] Specifically, during operation, the magnitude of current and voltage is measured through the intelligent control module 4. When current flows through the intelligent control module 4, the high voltage is converted into low voltage through the transformer in the PT cabinet, so that we can measure it. Through the setting of the intelligent control module 4, the current and voltage signals are collected to obtain accurate data. The processor in the intelligent control module 4 will process and calculate the collected current and voltage signals to obtain information such as power, frequency, power factor, harmonics, etc. This information is important feedback on the operating status of the power system and is used to monitor the health of the power system and predict potential faults. When maintaining and replacing the equipment in the cabinet 1, it is necessary to move the trolley body 3 out of the cabinet 1 and put the part to be repaired into the cabinet 1. Or the entire system is isolated from the power grid for maintenance and overhaul. At this time, the positioning component is retracted through the control component, and the installation component is reset synchronously, so that the trolley body 3 can be moved out of the trolley room, and the trolley body 3 drives the sliding frame 5 to move. At this time, the roller 7 rotates, and the sliding frame 5 and the slide rail 6 move relative to each other until the trolley body 3 is moved out, and then the overhaul can be started. After the overhaul is completed, the slide frame 5 is placed in the trolley room, and the roller 7 is in contact with the top of the cable room. The setting of the slide rail 6 can ensure that the moving direction of the trolley body 3 does not deviate, thereby improving the installation speed. After the trolley body 3 moves to the installation position, the position of the trolley body 3 can be fixed by the positioning component and the control component.

[0025] like Figures 5 to 8 As shown, the positioning assembly is installed on the sliding frame 5 and is used to fix the position of the moving assembly. The positioning assembly includes a positioning frame 8, a plug-in plate 9, a positioning groove 10 and a positioning portion. The positioning frame 8 is fixedly installed on the partition 2, and the plug-in plate 9 is fixedly installed on the sliding frame 5. The plug-in plate 9 is adapted to the positioning frame 8. Positioning grooves 10 are provided on the upper and lower sides of the plug-in plate 9. The positioning portion is installed on the positioning frame 8 and is used to fix the relative positions of the positioning frame 8 and the plug-in plate 9.

[0026] Specifically, when installing the trolley body 3, as the trolley body 3 moves, the sliding frame 5 drives the plug-in plate 9 to move until the plug-in plate 9 drives the positioning groove 10 to move to the position of the positioning portion. At this time, through the setting of the positioning portion, the relative position between the plug-in plate 9 and the positioning frame 8 can be fixed, thereby fixing the position of the sliding frame 5.

[0027] The above, such as Figure 7 , Fig. 9As shown, the positioning part includes a positioning plate 11, a first spring 12 and a connecting ear 13. Two positioning plates 11 are slidably installed on the positioning frame 8. The two positioning plates 11 are symmetrically arranged relative to the plug-in board 9, driving the positioning plates 11 to adapt to the positioning groove 10. Multiple first springs 12 are fixedly installed on the two positioning plates 11 at equal distances. The multiple first springs 12 are fixedly connected to the positioning frame 8. Connecting ears 13 are fixedly installed at both ends of the two positioning plates 11, wherein a sliding groove 14 is provided at the position where the positioning frame 8 and the connecting ear 13 are slidably matched, and the sliding groove 14 is adapted to the connecting ear 13.

[0028] Specifically, when the plug-in board 9 enters the positioning frame 8, as the plug-in board 9 moves, the plug-in board 9 contacts the positioning plate 11, at which time the first spring 12 begins to be compressed, and the connecting ear 13 slides along the direction of the slide groove 14 until the positioning groove 10 moves to the installation position. At this time, the positioning plate 11 enters the interior of the positioning groove 10, which can fix the position between the plug-in board 9 and the positioning frame 8.

[0029] like Figure 6 As shown, the control assembly is installed on the sliding frame 5 and is used to control the position of the positioning assembly. The control assembly includes a driving gear 15, a driven gear 16, an intermediate gear 17, a knob 18 and an adjustment part. The driving gear 15 is rotatably installed inside the sliding frame 5. Two driven gears 16 are symmetrically and rotatably installed inside the sliding frame 5. Two intermediate gears 17 are rotatably installed inside the sliding frame 5. The two intermediate gears 17 are respectively meshed with the two driven gears 16, and the two intermediate gears 17 are both meshed with the driving gear 15. The knob 18 is rotatably installed on the sliding frame 5, and the knob 18 is fixedly connected to the driving gear 15. An adjustment part is installed inside the sliding frame 5 to adjust the positions of the two positioning plates 11.

[0030] Specifically, when the trolley body 3 needs to be removed, first hold the knob 18, turn the knob 18 to drive the driving gear 15 to rotate, the driving gear 15 drives the intermediate gear 17 to rotate, the intermediate gear 17 drives the driven gear 16 to rotate, thereby driving the adjustment part to move, and through the cooperation of the adjustment part and the connecting ear 13, the positioning plate 11 can be disengaged from the positioning groove 10, thereby removing the trolley body 3.

[0031] The above, such as Figure 6 , Figure 7 As shown, the adjustment part includes a transmission shaft 19 and an elliptical cam 20. Two transmission shafts 19 are symmetrically and rotatably installed inside the sliding frame 5. The two transmission shafts 19 are respectively fixedly connected to the driven gear 16. The ends of the two transmission shafts 19 away from the driven gear 16 are fixedly installed with elliptical cams 20. The upper and lower sides of the elliptical cams 20 are slidably abutted against the connecting ears 13.

[0032] Specifically, as the driven gear 16 rotates, the driven gear 16 drives the transmission shaft 19 to rotate. Under normal conditions, the distance between the upper and lower ends of the elliptical cam 20 is at the shortest position. At this time, the positioning plate 11 and the positioning groove 10 are in a matching state. As the transmission shaft 19 rotates, the transmission shaft 19 drives the elliptical cam 20 to rotate, and the elliptical cam 20 is rotated 90°. At this time, the elliptical cam 20 is in contact with the bottom of the connecting ear 13. At this time, the distance between the upper and lower ends of the elliptical cam 20 is at the longest position, and the positioning plate 11 is disengaged from the positioning groove 10.

[0033] like Figures 10 to 12 As shown, the mounting assembly is installed on the trolley body 3 and is used to fix the position of the trolley body 3. The mounting assembly includes a slide 21, a mounting frame 22, a fixing portion, a disassembling portion and a resetting portion. Slides 21 are symmetrically and fixedly installed on both sides of the trolley body 3, and mounting frames 22 are fixedly installed on both sides of the cabinet 1. The two mounting frames 22 are symmetrically arranged, and the mounting frames 22 and the slide 21 are slidably matched. A fixing portion is installed on the two mounting frames 22 for fixing the position of the mounting frames 22 and the slide 21. A disassembling portion is installed on the two mounting frames 22 for disassembling the trolley body 3. Resetting portions are installed inside the two disassembling portions for restoring the position of the fixing portion.

[0034] Specifically, when installing the trolley body 3, the slide 21 moves with the movement of the trolley body 3. At this time, relative sliding occurs between the slide 21 and the mounting frame 22. When the slide 21 moves to the installation position, the relative position between the slide 21 and the mounting frame 22 is automatically fixed under the action of the reset part through the setting of the fixing part. When the trolley body 3 needs to be disassembled, the disassembly part is started, the fixing part is removed, and the trolley body 3 can be removed.

[0035] The above, such as Figures 10 to 12 As shown, the fixed part includes a rotating shaft 23, a rotating frame 24, an abutment block 25 and a fixed groove 26. Two rotating shafts 23 are fixedly and symmetrically installed inside the two mounting frames 22. A rotating frame 24 is rotatably installed on each rotating shaft 23. The two rotating frames 24 on each mounting frame 22 are symmetrically arranged. An abutment block 25 is fixedly installed on one end of each rotating frame 24. Fixed grooves 26 are opened on both sides of the inside of the two slides 21, and the fixed grooves 26 are adapted to the abutment blocks 25.

[0036] Specifically, when installing the trolley body 3, the slide 21 moves with the movement of the trolley body 3. At this time, the slide 21 contacts the abutment block 25 and presses the abutment block 25. The abutment block 25 rotates around the rotating shaft 23 under the action of the rotating frame 24 until the slide 21 drives the fixed groove 26 to move to the installation position. At this time, the rotating frame 24 returns to its original position under the action of the reset part, and the abutment block 25 enters the fixed groove 26, thereby fixing the position between the slide 21 and the mounting frame 22 through the cooperation between the fixed groove 26 and the abutment block 25.

[0037] The above, such as Figures 10 to 12 As shown, the disassembly part includes a movable frame 27, a slider 28, a fixed cylinder 29, a top frame 30, an electric cylinder 31 and a sensor 32. The movable frames 27 are slidably installed inside the two mounting frames 22. The slider 28 is fixedly installed at one end of each rotating frame 24 away from the abutment block 25. The slider 28 is slidably installed on the movable frame 27. The fixed cylinder 29 is fixedly installed on the two mounting frames 22. The top frame 30 is slidably installed on the two fixed cylinders 29. The top frame 30 is fixedly connected to the movable frame 27. The electric cylinder 31 is fixedly installed on the two fixed cylinders 29. The output end of the electric cylinder 31 abuts against the top frame 30. A sensor 32 is fixedly installed on each positioning plate 11.

[0038] Specifically, when the elliptical cam 20 is set to push the connecting ear 13 to move along the slide groove 14 and drive the positioning plate 11 to move, the first spring 12 will be compressed and the sensor 32 will contact the inner wall of the positioning frame 8. The sensor 32 is triggered at this time, wherein a signal transmitter is provided on the sensor 32 and a matching signal receiver is provided on the electric cylinder 31. When the sensor 32 is triggered, a signal is transmitted to the electric cylinder 31. At this time, the electric cylinder 31 is started, and the electric cylinder 31 pushes the top frame 30 and the fixed cylinder 29 to move relative to each other until the top frame 30 drives the moving frame 27 to move. As the moving frame 27 moves, the slider 28 slides on the corresponding moving frame 27, thereby driving the rotating frame 24 to rotate, so that the abutment block 25 can be separated from the fixed groove 26.

[0039] The above, such as Fig.12 As shown, the reset portion includes a second spring 33, an annular groove 34 and an elastic rope 35. The second spring 33 is fixedly installed inside each fixed cylinder 29, and the second spring 33 is fixedly connected to the top frame 30. An annular groove 34 is opened at both ends of each slider 28, and an elastic rope 35 is tensioned between every two adjacent annular grooves 34.

[0040] Specifically, during the installation of the trolley body 3, when the rotating frame 24 rotates, the two sliders 28 on the moving frame 27 move in the opposite direction, thereby applying tension to the elastic rope 35, and the second spring 33 is stretched at this time. When the abutment block 25 enters the fixed groove 26, the tension applied to the elastic rope 35 is removed, and the second spring 33 is reset.

[0041] When the trolley body 3 is installed, the cabinet door is opened first, the trolley body 3 is placed in the installation position, and the trolley body 3 is pushed to move. At this time, the trolley body 3 drives the sliding frame 5 to move. At this time, the roller 7 rotates, and the sliding frame 5 and the slide rail 6 move relative to each other, and the sliding frame 5 is placed in the trolley room. At this time, the roller 7 abuts against the top of the cable room. The setting of the slide rail 6 can ensure that the moving direction of the trolley body 3 does not deviate, thereby improving the installation speed. As the trolley body 3 moves, the sliding frame 5 drives the plug-in board 9 to move. When the plug-in board 9 enters the positioning frame 8, as the plug-in board 9 moves, the plug-in board 9 contacts the positioning plate 11. At this time, the first spring 12 begins to be compressed, and the connecting ear 13 slides along the direction of the slide groove 14 until the positioning groove 10 moves to the installation position. At this time, the positioning plate 11 enters the positioning groove 10 to fix the position between the plug-in board 9 and the positioning frame 8.

[0042] At the same time, the slide 21 moves with the movement of the trolley body 3. At this time, relative sliding occurs between the slide 21 and the mounting frame 22. At this time, the slide 21 contacts the abutment block 25 and presses the abutment block 25. The abutment block 25 rotates around the rotating shaft 23 as the center under the action of the rotating frame 24 until the slide 21 drives the fixed groove 26 to move to the installation position. When the abutment block 25 enters the fixed groove 26, the tension applied to the elastic rope 35 is removed, and the second spring 33 is reset. At this time, the rotating frame 24 returns to its original position, and the abutment block 25 enters the fixed groove 26, thereby fixing the position between the slide 21 and the mounting frame 22 through the cooperation of the fixed groove 26 and the abutment block 25, and the trolley body 3 can be installed.

[0043] When maintaining and replacing the equipment in the cabinet 1, it is necessary to move the trolley body 3 out of the cabinet 1, isolate the part or the entire system to be repaired from the power grid, and perform maintenance and repair. When the trolley body 3 needs to be removed, first hold the knob 18, turn the knob 18 to drive the active gear 15 to rotate, the active gear 15 drives the intermediate gear 17 to rotate, and the intermediate gear 17 drives the driven gear 16 to rotate. As the driven gear 16 rotates, the driven gear 16 drives the transmission shaft 19 to rotate. The distance between the upper and lower ends of the elliptical cam 20 under normal conditions is at the shortest position. At this time, the positioning plate 11 and the positioning groove 10 are in a matching state. As the transmission shaft 19 rotates, the transmission shaft 19 drives the elliptical cam 20 to rotate, and the elliptical cam 20 is rotated through 90°. At this time, the elliptical cam 20 abuts against the bottom of the connecting ear 13. At this time, the distance between the upper and lower ends of the elliptical cam 20 is at the longest position, and the positioning plate 11 is disengaged from the positioning groove 10.

[0044] Through the setting of the elliptical cam 20, when the first spring 12 is compressed and the sensor 32 contacts the inner wall of the positioning frame 8, the sensor 32 is triggered at this time, wherein a signal transmitter is arranged on the sensor 32, and a matching signal receiver is arranged on the electric cylinder 31. When the sensor 32 is triggered, a signal is transmitted to the electric cylinder 31, and the electric cylinder 31 is started at this time, and the electric cylinder 31 pushes the top frame 30 and the fixed cylinder 29 to move relative to each other until the top frame 30 drives the mobile frame 27 to move. With the movement of the mobile frame 27, the two sliders 28 on the mobile frame 27 move in the opposite direction, thereby applying tension to the elastic rope 35. The side length of the elastic rope 35 and the second spring 33 are stretched at this time, so that the trolley body 3 can be moved out and maintenance can be started.
