Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage switchgear, and more particularly to an indoor metal-clad high-voltage switchgear. Background Art

[0002] Indoor metal-clad high-voltage switchgear requires circuit breakers to be mounted on a removable trolley during use. This provides excellent interchangeability and facilitates maintenance and overhaul. When circuit breakers need to be replaced or other repairs need to be performed, simply pull out the trolley. Furthermore, this type of switchgear features metal cladding, providing comprehensive safety protection.

[0003] Among existing publicly available technical documents, Chinese patent publication number CN209344617U discloses an indoor metal-clad removable high-voltage switchgear. This high-voltage switchgear primarily features a cable bracket fixed to the right side of a current transformer, a lightning rod positioned on the lower surface of the cable bracket, and a line bushing positioned on the upper surface of the armored cabinet. The device boasts high reliability, a high level of protection, compact size, and ease of maintenance. It also fully seals primary components, ensuring grounding continuity and improving the reliability and stability of the high-voltage switchgear. However, this high-voltage switchgear presents the following issues during use:

[0004] During the trolley operation of the high-voltage switchgear, the circuit breaker must be disconnected from the energized circuit before the trolley can be pulled to separate the circuit breaker. However, some personnel may mistakenly pull the trolley to separate the circuit breaker without disconnecting the circuit. This will cause a high-voltage arc to be generated by directly disconnecting the trolley in the closed state. Such a high-voltage arc will cause safety problems for equipment and personnel. The safety of the high-voltage switchgear is poor. For this reason, an indoor metal-clad high-voltage switchgear is needed. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an indoor metal-clad high-voltage switchgear.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an indoor metal-clad high-voltage switchgear, comprising an armored cabinet body, a trolley slidably connected to the interior of the armored cabinet body, a limit slider fixedly installed on the top of the trolley, a slide frame slidably connected to the inner wall of the limit slider, a double-sided anti-movement mechanism provided inside the slide frame; the double-sided anti-movement mechanism comprises a support frame fixedly arranged inside the slide frame, and a linkage screw is rotatably connected to the inner wall of the support frame, a drive motor is fixedly installed on one end of the support frame, and the drive motor is used to drive the linkage The screw rotates, and the outer wall of the linkage screw is threadedly connected to two articulated sleeve blocks, and the two threads on the outer wall of the linkage screw are opposite and symmetrical; the bottom end of the inner wall of each articulated sleeve block is fixedly connected to a hinge shaft, and the outer wall of each articulated shaft is rotatably connected to a sleeve rod, and a push shaft is rotatably connected to the inside of the sleeve rod and away from the articulated shaft, and a hinge block is fixedly connected to the top of the push shaft; a sleeve plate is fixedly connected to one side of the articulated block; a detection embedded component is provided on the upper surface of the sleeve plate; a wheel linkage anti-movement mechanism is installed under the trolley.

[0007] Preferably, the two hinged sleeves are slidably connected to the inner wall of the support frame, and the outer wall of the hinged sleeve and the inner wall of the support frame are both smooth surfaces; the two threads on the outer wall of the linkage screw are opposite and symmetrically opened, and the interior of each sleeve is rotatably connected to a positioning column, and the two positioning columns are fixedly connected to the sliding frame; a pressure sensor is embedded and fixed on one side of the sleeve, and a safety door is hinged on the outer wall of the armored cabinet, and a controller is fixedly installed on one side of the safety door.

[0008] In this technical solution, the linkage screw is driven to rotate by a driving motor, and the linkage screw rotates inside the support frame. The articulated sleeve drives the articulated shaft to move backward, while the other articulated sleeve moves forward. The sleeve drives the push shaft to move toward the side of the limit slider, and the push shaft drives the articulated block to move toward the side of the limit slider. The sleeve plate drives the pressure sensor to move toward the side of the limit slider, and the sleeve plate rotates counterclockwise on the outer wall of the positioning column, while the other sleeve plate rotates clockwise on the outer wall of the other positioning column. The pressure sensor is squeezed on the side of the limit slider. When the pressure value sensed by the pressure sensor is the same as the pressure value set by the controller, the driving motor is turned off by the controller. The two sleeve plates can limit and prevent the two sides of the limit slider from moving. The electric cylinder pushes the push bar to move right, and the positioning block can move right synchronously. The positioning block is inserted into the positioning hole inside the limit slider, and the positioning block is positioned and plugged into the positioning hole.

[0009] Preferably, the detection embedded component includes an electric cylinder fixedly arranged on the upper surface of the sleeve plate;

[0010] A push bar is fixedly installed at the output end of the electric cylinder, and a positioning block is fixedly connected to the top end of the push bar. A positioning hole is opened on one side of the inner wall of the support frame, and the vertical cross-sectional area of ​​the positioning block is smaller than the vertical cross-sectional area of ​​the positioning hole; one end of the sliding frame is fixedly connected to a support bar, and a trolley terminal is provided on one side of the support bar, and the trolley terminal is fixedly connected to the trolley. The outer wall of the trolley terminal is connected to a power terminal, and the power terminal is fixedly connected to the armored cabinet;

[0011] A power probe is fixedly connected to the top of the outer wall of the power terminal, and a current detector is fixedly mounted on the top of the power probe. A battery is fixedly connected to one side of the current detector. The power terminal is plugged into the trolley terminal, and both the trolley terminal and the power terminal are made of copper. The battery and current detector are both fixedly connected to the armored cabinet, and the battery is used to power the current detector.

[0012] In this technical solution, a battery powers the current detector. The current detector's power probe can be connected to the power terminal to energize it. The current detector detects the current. If no current is present, the circuit breaker is closed. This causes the trolley to move the circuit breaker right, which in turn moves the trolley terminal right, separating the trolley terminal from the power terminal. When the current detector detects current, the controller activates the drive motor, achieving the drive motor's driving operation.

[0013] Preferably, the wheel linkage anti-movement mechanism includes a socket plate fixedly mounted under the trolley; one side of the socket plate is fixedly connected to two limit shafts, a roller is rotatably connected to the outer wall of the limit shaft, a slide rail is rotatably connected to the lower outer wall of the roller, a guide frame is fixedly mounted on the bottom end of the slide rail, and the guide frame is fixedly connected to the armored cabinet; the inner wall of the guide frame is rotatably connected to a transmission screw, and a reduction motor is fixedly mounted on one side of the inner wall of the guide frame, the reduction motor is used to drive the transmission screw to rotate, the outer wall of the transmission screw is threadedly connected to two threaded sleeves, and a slide bar is slidably connected to the bottom end of the threaded sleeve, and the slide bar is fixedly connected to the guide frame;

[0014] The upper surface of each threaded sleeve is fixedly connected to a toothed plate, which is meshed and connected to a gear on the upper surface of the toothed plate. The inner wall of the gear is rotatably connected to a positioning shaft, which is fixedly connected to the guide frame. A limit sleeve is fixedly mounted on one side of the gear. A proximity sensor is fixedly mounted on the inner wall of the limit sleeve. A trolley sleeve is fixedly connected to one side of the sleeve plate, and the trolley sleeve is slidably connected to the slide rail. The inner wall of the trolley sleeve is threadedly connected to a trolley screw. A bearing sleeve is rotatably connected to the outer wall of the trolley screw at a position away from the trolley sleeve, and the bearing sleeve is fixedly connected to the slide rail. A circuit breaker is provided above the trolley sleeve, and the circuit breaker is fixedly connected to the trolley. The vertical cross-section of the two toothed plates is L-shaped, and the toothed plates and gears are made of stainless steel. The vertical cross-section of the positioning shaft is circular, and the limit sleeve is rotatably connected to the positioning shaft.

[0015] In this technical solution, the reduction motor drives the transmission screw to rotate, and the transmission screw drives the two threaded sleeves to move right under the action of the thread transmission force, the threaded sleeve drives the tooth plate to move right, the gear rotates counterclockwise on the outer wall of the positioning shaft, and the limit sleeve rotates counterclockwise along the outer wall of the positioning shaft. When the limit sleeve rotates and contacts the outer wall of the roller, the two limit sleeves are used to limit and prevent the two rollers from moving to the right. The proximity sensor approaches the roller and senses the roller through the proximity sensor. When the roller is sensed, the reduction motor is turned off through the controller.

[0016] The technical effects and advantages of the present invention are as follows:

[0017] 1. The present invention adopts a bilateral anti-movement mechanism. When the circuit breaker is not closed and the current detector detects current, the driving motor drives the linkage screw to rotate. The two articulated sleeves approach each other under the action of the thread transmission force, and the articulated shaft causes the sleeve rod to move backward. The sleeve rod drives the push shaft to move toward the side of the limit slider. The sleeve plate rotates counterclockwise on the outer wall of the positioning column, and the other sleeve plate rotates clockwise on the outer wall of the other positioning column. When the pressure value sensed by the pressure sensor is the same as the pressure value set by the controller, the driving motor is turned off by the controller, and the two sleeve plates can limit the two sides of the limit slider to prevent movement, thereby avoiding the direct disconnection of the trolley in the closed state, which may cause high-voltage arc, avoid equipment damage and personal injury, and greatly improve the safety of high-voltage switchgear.

[0018] 2. The present invention utilizes a detection embedded component and a current detector powered by a battery. The power probe on the current detector can be connected to the power terminal to energize it. When there is no current, it is known that the circuit breaker is closed. External maintenance personnel can insert the tool into the inner wall of the end of the trolley screw and perform the normal pull-out and separation operation of the trolley. When the current detector detects the current, the drive motor is started by the controller and the electric cylinder is moved at the same time. The electric cylinder pushes the push bar to the right, and the positioning block is inserted into the positioning hole inside the limit slider. The trolley can continue to perform internal limit movement prevention, avoiding the right movement and separation operation of the trolley when the circuit breaker is not closed, and avoiding the high-voltage arc generated by directly disconnecting the trolley in the closed state. The large high-voltage switchgear is safer to use.

[0019] 3. The present invention adopts a wheel linkage anti-movement mechanism. The reduction motor drives the transmission screw to rotate, and the transmission screw drives the two threaded sleeves to move right under the action of the thread transmission force. The tooth plate drives the gear to rotate counterclockwise, the gear drives the limit sleeve to rotate counterclockwise, and the positioning shaft drives the proximity sensor to rotate counterclockwise. The two limit sleeves are used to limit the two rollers to prevent movement, so as to prevent the two rollers on the trolley from moving to the right and rolling in the closed state. This avoids the generation of high-voltage arc and greatly improves the safety of the high-voltage switchgear.

[0020] Based on the interplay of these multiple functions, first, when the current detector detects current, the controller activates the drive motor. Second, two sleeves prevent movement on both sides of the limit slider, and the positioning block is inserted into the positioning hole inside the limit slider. Finally, the two sleeves prevent movement of the two rollers. In summary, when current is detected, multiple anti-movement operations can be implemented, preventing the trolley from being directly disconnected in the closed state, preventing equipment damage and personal injury caused by high-voltage arcs, and significantly improving the safety of high-voltage switchgear.

[0040] The vertical cross-sections of the two tooth plates 37 are both L-shaped, and the tooth plates 37 and the gear 38 are both made of stainless steel. The vertical cross-section of the positioning shaft 39 is circular, and the limiting sleeve 40 is rotationally connected to the positioning shaft 39.

[0041] The working principle of the indoor metal armored high-voltage switchgear of the present invention is as follows:

[0042] First, when the armored cabinet 1 is used, the armored cabinet 1 is reinforced with metal armor, so that the armored cabinet 1 is more stable and firm during outdoor use, and has better resistance to external impact. Then, by closing the safety door 20, the safety door 20 and the armored cabinet 1 are closed. After closing, the circuit breaker 45 can be opened by the controller 21, so that the circuit breaker 45 is connected to the mains power, and the trolley terminal 23 on the trolley 2 is connected to the power terminal 24. The outer wall insulation material of the power terminal 24 is firmly fixed to the armored cabinet 1. After the top of the power terminal 24 is connected, external docking is performed, and power is supplied to the trolley terminal 23 on the trolley 2 through the circuit breaker 45, so that the trolley terminal 23 supplies power to the power terminal 24, realizing high-voltage power supply. At the same time, closing the circuit breaker 45 can cut off the high-voltage circuit.

[0043] Secondly, when the present invention is embedded for detection, the current detector 26 is powered by the battery 27, and the power probe 25 on the current detector 26 can be connected to the power terminal 24 to energize, so that the current is detected by the current detector 26. When there is no current, it is known that the circuit breaker 45 is closed. In this way, the external maintenance personnel can insert the tool into the inner wall of the end of the trolley screw 43. By rotating the trolley screw 43, the trolley screw 43 rotates stably inside the bearing sleeve 44. At the same time, the trolley screw 43 drives the trolley sleeve block 42 to move right under the action of the threaded transmission force, and at the same time, the trolley sleeve block 42 slides to the right at the upper limit of the slide rail 31. At the same time, the trolley sleeve block 42 drives the sleeve plate 28 to move right, and the sleeve plate 28 causes the two limit shafts 29 to move right. The limit shafts 29 roll right along the outer wall of the slide rail 31, and the trolley 2 drives the circuit breaker 45 to move right, and the trolley 2 drives the trolley terminal 23 to move right. The trolley terminal 23 and the power terminal 24 are separated, and the trolley 2 can be moved out from the armored cabinet 1.

[0044] When the current detector 26 detects the current, the drive motor 7 is started through the controller 21 to realize the driving operation of the drive motor 7.

[0045] Then, when the present invention performs bilateral anti-movement, the linkage screw 6 is driven to rotate by the drive motor 7. The linkage screw 6 rotates inside the support frame 5. At the same time, the linkage screw 6 drives the two articulated sleeves 8 to approach each other under the action of the thread transmission force. The articulated sleeve 8 drives the articulated shaft 9 to move backward, while the other articulated sleeve 8 moves forward. The articulated shaft 9 causes the sleeve rod 10 to move backward. The sleeve rod 10 drives the push shaft 11 to move toward the side of the limit slider 3. The push shaft 11 drives the articulated block 12 to move toward the side of the limit slider 3. The articulated block 12 drives the sleeve plate 13 to move toward the side of the limit slider 3. At the same time, the sleeve plate 13 drives the pressure sensor 16 to move toward the side of the limit slider 3. The sleeve plate 13 rotates counterclockwise on the outer wall of the positioning column 14, while the other sleeve plate 13 rotates clockwise on the outer wall of the other positioning column 14. In this way, the two sleeve plates 13 are respectively squeezed on the two side surfaces of the limit slider 3, and the pressure sensor 16 is squeezed on the side surface of the limit slider 3. When the pressure value sensed by the pressure sensor 16 is the same as the pressure value set by the controller 21, the drive motor 7 is turned off by the controller 21.

[0046] The two sleeve plates 13 can limit and prevent movement on both sides of the limit slider 3, and at the same time start the electric cylinder 17, the electric cylinder 17 pushes the push bar 18 to move right, and the push bar 18 makes the positioning block 19 move right, and the positioning block 19 can move right synchronously, and the positioning block 19 is inserted into the positioning hole 15 inside the limit slider 3. By positioning the positioning block 19 and the positioning hole 15, the handcart 2 can continue to be internally limited and prevented from moving, thereby avoiding the handcart 2 from moving by accidental operation.

[0047] Finally, when the present invention performs wheel linkage anti-movement, the controller 21 starts the reduction motor 34, the reduction motor 34 drives the transmission screw 33 to rotate, and the transmission screw 33 drives the two threaded sleeves 35 to move right under the action of the thread transmission force, and the two threaded sleeves 35 slide right on the outer wall of the slide bar 36.

[0048] At the same time, the threaded sleeve 35 drives the toothed plate 37 to move right, and the toothed plate 37 drives the gear 38 to rotate counterclockwise. The gear 38 rotates counterclockwise on the outer wall of the positioning shaft 39, and the gear 38 drives the limit sleeve 40 to rotate counterclockwise. The limit sleeve 40 rotates counterclockwise along the outer wall of the positioning shaft 39, and the positioning shaft 39 drives the proximity sensor 41 to rotate counterclockwise. When the limit sleeve 40 rotates and contacts the outer wall of the roller 30, the two limit sleeves 40 are used to limit the two rollers 30 to prevent them from moving right. The limit sleeves 40 then drive the proximity sensor 41 to rotate counterclockwise. The proximity sensor 41 approaches the roller 30, and the proximity sensor 41 senses the roller 30. When the roller 30 is sensed, the controller 21 turns off the reduction motor 34, thus performing a linkage anti-movement operation on the two rollers 30.
