Description

Technical Field

[0001] This invention belongs to the field of FTU intelligent controller technology, specifically relating to a pole-mounted FTU intelligent controller. Background Technology

[0002] A pole-mounted FTU, or feeder terminal unit, is a distribution network automation intelligent measurement and control terminal installed on the poles of 10kV distribution network overhead lines, used in conjunction with pole-mounted load switches, circuit breakers, and sectionalizing switches. As the core field unit of the feeder automation system, it undertakes the core functions of distribution network line operation data acquisition, switch status monitoring, and remote control. It is widely deployed at the sectionalizing, connecting, and demarcation switch points of urban and rural distribution network overhead lines, and is a core field measurement and control equipment for improving the reliability of distribution network power supply and promoting intelligent operation and maintenance of distribution networks.

[0003] The communication and power interfaces of existing pole-mounted FTU intelligent controllers are mostly located at the bottom of the equipment housing or on the side facing the ground. Although the interfaces use aviation plugs and have IP65 / IP67 protection ratings, during long-term outdoor operation, the downward or tilted downward layout of the interfaces makes it easy for rainwater, condensation, snowmelt, and ground dust to accumulate and deposit around the interfaces. In addition, the outdoor environment is complex and changeable, with large temperature differences between day and night and strong ultraviolet radiation, which makes the interface seals prone to aging and failure. This leads to corrosion, water ingress, poor contact, or decreased insulation at the interfaces, which in turn causes equipment malfunctions, communication interruptions, or abnormal telemetry and telecontrol data, affecting the reliable operation of the distribution network automation system. Summary of the Invention

[0004] The purpose of this invention is to provide a simple and rationally designed column-mounted FTU intelligent controller in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A column-mounted FTU intelligent controller includes a housing, within which a motherboard is housed. The motherboard integrates a main control module, a power module, an I / O module, and a communication module. An interface panel is installed inside the housing. A wireless module is installed on one side of the housing. A protective device is provided on the surface of the housing. The protective device includes a mounting bracket fixed to the surface of the housing, with a guide rail fixedly connected to the bracket. The bracket secures the guide rail to the housing, ensuring its stability. A slider is slidably connected to the surface of the guide rail, and a mounting bracket is fixedly connected to the surface of the slider. The cooperation between the guide rail and the slider guides the movement direction of the mounting bracket. A clamping plate is fixedly connected to the surface of the housing, and a protective plate is fixedly connected to the mounting bracket. When the protective plate is closed, it cooperates with the clamping plate to block and protect the opening of the housing. A mounting cavity is formed on the side of the protective plate near the clamping plate, and a constraint component is installed in the mounting cavity. The main control module, power module, I / O module, communication module, and wireless module integrated in the housing are all existing technologies and will not be described in detail here.

[0006] As a further optimization of the present invention, the constraint component includes an outer bushing fixed in the mounting cavity. The outer bushing is made of rubber, which ensures both deformation capability and sealing effect. The inner wall of the outer bushing is integrally formed with a flexible inner bushing made of silicone rubber, fluororubber, or other materials to ensure its stability in long-term outdoor use. An exhaust valve and an intake valve communicating with its inner cavity are fixedly connected to the outer bushing. Both the exhaust valve and the intake valve are one-way valves. The design of the exhaust valve and the intake valve facilitates the operator's inflation and deflation operations of the airbag formed by the outer bushing and the flexible inner bushing. The surfaces of the exhaust valve and the intake valve are threaded with a first protective cover to protect the valve ports of the exhaust valve and the intake valve. A magnet is fixedly connected to the surface of the first protective cover. The exhaust valve and the intake valve are existing technologies and will not be described in detail here.

[0007] As a further optimization of the present invention, the surface of the protective plate is provided with a slot adapted to the magnet, and a magnetic absorbing piece is fixedly connected to the inner wall of the slot. The magnet and the magnetic absorbing piece are magnetically connected. After the operator removes the first protective cover, the first protective cover is placed on the protective plate by the magnetic attraction between the magnet and the magnetic absorbing piece to prevent the first protective cover from being lost.

[0008] As a further optimization of the present invention, a sealing gasket is fixedly connected to the side of the clamping plate near the protective plate to improve the sealing effect between the clamping plate and the protective plate, and a sealing plate is fixedly connected to the side of the protective plate near the outer shell to improve the sealing effect between the protective plate and the outer shell.

[0009] As a further optimization of the present invention, the number of guide rails is two, and the two guide rails are symmetrically arranged on the fixed frame. The clamping plate has a storage cavity on the side near the protective plate for storing the outer bushing. When the protective plate is closed, the outer bushing is inserted into the storage cavity to avoid the outer bushing from contacting the end face of the clamping plate, which would prevent the protective plate from closing completely. When the outer bushing is in contact with the cavity wall of the storage cavity, an auxiliary sealing gasket seals the gap between the protective plate and the clamping plate.

[0010] As a further optimization of the present invention, a locking device is provided on the fixed frame. The locking device includes a bracket fixed on the fixed frame, an insert plate fixedly connected to the bracket, and a lock housing fixedly connected to one side of the insert plate. The cooperation between the insert plate and the bracket fixes the lock housing in the designed position. A latch is slidably connected to the inner wall of the lock housing. A cover plate is fixedly connected to one side of the lock housing. A spring is fixedly connected between the cover plate and the latch. The spring applies a preload force to the latch under the restriction of the cover plate to ensure that the latch remains locked when no external force is applied. A limit frame is fixedly connected to the slider. A threaded groove is opened on the surface of the limit frame. A guide bolt is threadedly connected in the threaded groove. A pressure plate is slidably connected to the surface of the guide bolt. The guide bolt guides the movement direction of the pressure plate and constrains the maximum movement distance of the pressure plate to ensure the stability of the pressure plate during movement. A pressure block is fixedly connected to the side of the pressure plate facing the latch. When the operator pushes the pressure plate, the pressure plate and the pressure block press the latch to release the locking state of the latch.

[0011] As a further optimization of the present invention, the locking pin slides through the lock housing, and the end of the locking pin away from the spring is arc-shaped. A through hole is provided on the limiting frame, and the locking pin is inserted into the inner wall of the through hole. After the locking pin is inserted into the through hole, it cooperates with the limiting frame to lock the position of the slider, thereby restricting the position of the protective plate. The inner wall edge of the limiting frame away from the slider is provided with a guide chamfer. The guide chamfer guides the contact position between the limiting frame and the locking pin when the limiting frame moves towards the locking pin, and applies pressure to the locking pin during the movement of the limiting frame, thereby squeezing the locking pin.

[0012] As a further optimization of the present invention, the surface of the protective plate is provided with an inflation device. The inflation device includes a protective shell fixed to the surface of the protective plate, an air pump fixedly connected to the inner bottom wall of the protective shell, a conduit fixedly connected to the air outlet of the air pump, a connector fixedly connected to the air outlet end of the conduit, and a fixed sleeve movably connected to the connector. The fixed sleeve is adapted to the air inlet valve. When the operator inflates the airbag formed by the outer bushing and the flexible inner bushing, the connector is fixed to the air inlet valve through the fixed sleeve to realize the connection between the connector and the air inlet valve. A pressing sleeve is slidably connected to the surface of the protective shell. The pressing sleeve and the protective shell cooperate to form a protective structure to protect the air pump. A squeezing frame is fixedly connected to the inner wall of the pressing sleeve. The squeezing frame abuts against one end of the air pump. When the operator pushes the pressing sleeve, the pressing sleeve cooperates with the squeezing frame to press the air pump, so that the air pump enters the inflation state. The air pump is a manual air pump and is existing technology, which will not be described in detail here.

[0013] As a further optimization of the present invention, the surface of the protective plate is fixedly connected with a threaded post, and the fixing sleeve is threadedly connected to the threaded post. When the operator finishes inflation and removes the connector from the air inlet valve, the connector is fixed to the threaded post by the fixing sleeve to protect the connector. The surface of the protective shell is fixedly connected with a connecting rope, and the other end of the connecting rope is fixedly connected to a second protective cover. The connecting rope allows the operator to hang the second protective cover when removing it to prevent it from being lost. The second protective cover is threadedly connected to the air inlet of the air pump. The second protective cover protects the air inlet of the air pump, blocking the air inlet when it is not in use and preventing external dust and other impurities from entering the air inlet and causing blockage.

[0014] As a further optimization of the present invention, the surface of the protective shell is provided with a U-shaped groove to facilitate the installation of an air pump inside the protective shell by the operator. The connector is connected to the air pump through a conduit so that the air pumped out by the air pump is injected into the connector through the conduit. When the connector is fixed on the air inlet valve, the connector injects air into the air bladder formed by the outer bushing and the flexible inner bushing so as to expand the flexible inner bushing by air.

[0015] The beneficial effects of this invention are as follows: 1. By installing protective devices on the housing, the openings of the housing are covered after the cable connectors on the interface panel are installed. The housing, together with the interface panel and cable connectors, isolates them from the external environment, placing them in a closed chamber. This design can effectively prevent rainwater, condensation, and dust from entering, avoiding problems such as corrosion, water ingress, poor contact, or insulation degradation at the interface. This prevents equipment malfunctions, communication interruptions, or abnormal telemetry and telecontrol data, ensuring the reliable operation of the power distribution network automation system.

[0016] 2. A locking device is installed between the fixed frame and the slider to lock the position of the protective plate when it is opened or closed, ensuring that the protective plate is stably in the corresponding state and preventing the protective effect from being reduced due to shaking; at the same time, when the equipment is installed vertically, the protective plate can form a small platform when locked in the open state, which is convenient for operators to place tools and improve the convenience of maintenance operations.

[0017] 3. An inflation device is installed on the protective plate to inflate the airbag formed by the outer bushing and the flexible inner bushing. The inflation operation can be completed without carrying any tools. In addition, after the cable passes through the airbag, the airbag expands under the action of air pressure, clamping the cable and sealing the gaps between the cables, thereby improving the sealing and protection effect of the protective device.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example: Please refer to Figures 1-11 A column-mounted FTU intelligent controller includes a housing 1, within which a motherboard is housed. The motherboard integrates a main control module, a power module, an I / O module, and a communication module. An interface panel 2 is installed inside the housing 1, and a wireless module 3 is installed on one side of the housing 1. Both the interface panel 2 and the wireless module 3 are electrically connected to the motherboard. A protective device 4 is provided on the surface of the housing 1. The protective device 4 includes a mounting bracket 41 fixed to the surface of the housing 1, with a guide rail 42 fixedly connected to the mounting bracket 41. The mounting bracket 41 secures the guide rail 42 to the housing 1, ensuring the stability of the guide rail 42. A slider is slidably connected to the surface of the guide rail 42. 43. A mounting bracket 44 is fixedly connected to the surface of the slider 43. The guide rail 42 and the slider 43 cooperate to guide the movement direction of the mounting bracket 44. A clamping plate 45 is fixedly connected to the surface of the outer shell 1. A protective plate 47 is fixedly connected to the mounting bracket 44. When the protective plate 47 is closed, it cooperates with the clamping plate 45 to block and protect the opening position of the outer shell 1. A mounting cavity is opened on the side of the protective plate 47 near the clamping plate 45. A constraint component 48 is installed in the mounting cavity. The main control module, power module, I / O module, communication module, interface panel 2, and wireless module 3 integrated in the outer shell 1 are all existing technologies and will not be described in detail here.

[0022] Please see Figure 5 and Figure 6The constraint component 48 includes an outer bushing 481 fixed inside the mounting cavity. The outer bushing 481 is made of rubber, ensuring both deformation capability and sealing effect. A flexible inner bushing 482 is integrally formed on the inner wall of the outer bushing 481. The flexible inner bushing 482 is made of materials such as silicone rubber and fluororubber to ensure its stability during long-term outdoor use. An exhaust valve 483 and an intake valve 484, communicating with the inner cavity, are fixedly connected to the outer bushing 481. All 484 are one-way valves. The exhaust valve 483 and the intake valve 484 are designed to facilitate the operator's inflation and deflation of the air bladder formed by the outer bushing 481 and the flexible inner bushing 482. The surfaces of the exhaust valve 483 and the intake valve 484 are threaded with a first protective cover 485 to protect the valve ports of the exhaust valve 483 and the intake valve 484. A magnet 486 is fixedly connected to the surface of the first protective cover 485. The exhaust valve 483 and the intake valve 484 are existing technologies and will not be described in detail here.

[0023] Please see Figures 4-6 The surface of the protective plate 47 is provided with a slot 410 that is compatible with the magnet 486. A magnetic piece 411 is fixedly connected to the inner wall of the slot 410. The magnet 486 and the magnetic piece 411 are magnetically connected. After the operator removes the first protective cover 485, the first protective cover 485 is placed on the protective plate 47 by the magnetic attraction between the magnet 486 and the magnetic piece 411 to prevent the first protective cover 485 from being lost.

[0024] Please see Figure 3 and Figure 4 A sealing gasket 46 is fixedly connected to the side of the clamping plate 45 near the protective plate 47 to improve the sealing effect between the clamping plate 45 and the protective plate 47. A sealing plate 49 is fixedly connected to the side of the protective plate 47 near the outer shell 1 to improve the sealing effect between the protective plate 47 and the outer shell 1.

[0025] Please see Figure 4 There are two guide rails 42, which are symmetrically arranged on the fixed frame 41. The clamping plate 45 has a storage cavity on the side near the protective plate 47 to store the outer bushing 481. When the protective plate 47 is closed, the outer bushing 481 is inserted into the storage cavity to avoid the outer bushing 481 contacting the end face of the clamping plate 45, which would prevent the protective plate 47 from being completely closed. When the outer bushing 481 is in contact with the cavity wall of the storage cavity, the auxiliary sealing gasket 46 seals the gap between the protective plate 47 and the clamping plate 45.

[0026] Please see Figure 3 , Figure 7 , Figure 8 and Figure 9A locking device 5 is provided on the fixing frame 41. The locking device 5 includes a bracket 51 fixed on the fixing frame 41, a plate 52 fixedly connected to the bracket 51, and a lock housing 53 fixedly connected to one side of the plate 52. The cooperation between the plate 52 and the bracket 51 fixes the lock housing 53 in the designed position. A latch 54 is slidably connected to the inner wall of the lock housing 53. A cover plate 56 is fixedly connected to one side of the lock housing 53. A spring 55 is fixedly connected between the cover plate 56 and the latch 54. The spring 55 applies a preload force to the latch 54 under the restriction of the cover plate 56, ensuring that the latch 54 remains locked when no external force is applied. In the stopped state, a limit frame 57 is fixedly connected to the slider 43. The surface of the limit frame 57 is provided with a threaded groove, and a guide bolt 58 is threadedly connected in the threaded groove. A pressure plate 59 is slidably connected to the surface of the guide bolt 58. The guide bolt 58 guides the movement direction of the pressure plate 59 and constrains the maximum movement distance of the pressure plate 59 to ensure the stability of the pressure plate 59 during movement. A pressure block 510 is fixedly connected to the side of the pressure plate 59 facing the locking pin 54. When the operator pushes the pressure plate 59, the pressure plate 59 cooperates with the pressure block 510 to press the locking pin 54 to release the locking state of the locking pin 54.

[0027] Please see Figure 8 and Figure 9 The locking pin 54 slides through the lock housing 53. The end of the locking pin 54 away from the spring 55 is arc-shaped. A through hole is provided on the limiting frame 57. The locking pin 54 is inserted into the inner wall of the through hole. After the locking pin 54 is inserted into the through hole, it cooperates with the limiting frame 57 to lock the position of the slider 43, thereby restricting the position of the protective plate 47. The inner wall edge of the limiting frame 57 away from the slider 43 is provided with a guide chamfer. The setting of the guide chamfer guides the contact position between the limiting frame 57 and the locking pin 54 when the limiting frame 57 moves towards the locking pin 54, and applies pressure to the locking pin 54 during the movement of the limiting frame 57, thereby squeezing the locking pin 54.

[0028] Please see Figure 3 , Figure 10 and Figure 11An inflation device 6 is provided on the surface of the protective plate 47. The inflation device 6 includes a protective shell 61 fixed to the surface of the protective plate 47. An air pump 62 is fixedly connected to the inner bottom wall of the protective shell 61. A conduit 63 is fixedly connected to the air outlet of the air pump 62. A connector 64 is fixedly connected to the air outlet of the conduit 63. A fixing sleeve 65 is movably connected to the connector 64. The fixing sleeve 65 is adapted to the air inlet valve 484. When the operator inflates the airbag formed by the outer bushing 481 and the flexible inner bushing 482, the connector 64 is fixed to the air inlet valve 484 through the fixing sleeve 65. To achieve the connection between connector 64 and air inlet valve 484, a pressing sleeve 66 is slidably connected to the surface of protective shell 61. The pressing sleeve 66 and protective shell 61 cooperate to form a protective structure to protect air pump 62. A squeezing frame 67 is fixedly connected to the inner wall of pressing sleeve 66. The squeezing frame 67 abuts against one end of air pump 62. When the operator pushes pressing sleeve 66, pressing sleeve 66 cooperates with squeezing frame 67 to press air pump 62, so that air pump 62 enters the inflation state. Among them, air pump 62 is a manual air pump 62 and is existing technology, which will not be described in detail here.

[0029] Please see Figure 3 and Figure 10 A threaded post 68 is fixedly connected to the surface of the protective plate 47. A fixing sleeve 65 is threadedly connected to the threaded post 68. When the operator finishes inflation and removes the connector 64 from the air inlet valve 484, the connector 64 is fixed to the threaded post 68 by the fixing sleeve 65 to protect the connector 64. A connecting rope 69 is fixedly connected to the surface of the protective shell 61. The other end of the connecting rope 69 is fixedly connected to the second protective cover 610. The setting of the connecting rope 69 allows the operator to hang the second protective cover 610 when removing it to prevent the second protective cover 610 from being lost. The second protective cover 610 is threadedly connected to the air inlet of the air pump 62. The second protective cover 610 protects the air inlet of the air pump 62, so that the air inlet is blocked when not in use, preventing external dust and other impurities from entering the air inlet and causing blockage.

[0030] Please see Figure 10 The protective shell 61 has a U-shaped groove on its surface, which makes it convenient for operators to install the air pump 62 inside the protective shell 61. The connector 64 is connected to the air pump 62 through the conduit 63, so that the air pumped out by the air pump 62 is injected into the connector 64 through the conduit 63. When the connector 64 is fixed on the air inlet valve 484, the connector 64 injects air into the air bladder formed by the outer bushing 481 and the flexible inner bushing 482, so that the flexible inner bushing 482 is expanded by air.

[0031] To ensure the stability of the protective device 4, locking device 5, and inflation device 6 in long-term outdoor environments, their parts and structures are made of materials suitable for outdoor environments.

[0032] It should be noted that, when the line is running, the three-phase voltage, current and switch position signals of the PT / CT secondary side are connected to the interface panel 2 via an aviation plug. The interface panel 2, together with the motherboard and wireless module 3, ensures that the device continues to operate when the mains power fails. When installing the aviation plug, ensure that the protective plate 47 is in the open position. Pull the outer bushing 481 to change the width of the through hole between the outer bushing 481 and the flexible inner bushing 482. After the through hole width increases, pass the aviation plug through the through hole and insert it into the corresponding interface on the interface panel 2. After the aviation plug passes through the through hole, the cable remains in the through hole. After all aviation plugs are installed, press the pressure plate 59. The pressure plate 59 pushes the pressure block 510 and squeezes the locking pin 54. The locking pin 54 compresses the spring 55 and slides out of the through hole. After the locking pin 54 has completely slid out of the through hole, the limit frame 57 is unlocked. Push the limit frame 57. The limit frame 57, together with the slider 43, guide rail 42 and mounting bracket 44, moves the protective plate 47, the constraint assembly 48 and the cable of the aviation plug. When the limit frame 57 has completely moved out of the end of the lock housing 53, release the pressure plate 59. The locking pin 54 stops compressing the spring 55. The spring 55 rebounds and pushes the locking pin 54 to reset. When the protective plate 47 moves into position, it contacts the clamping plate 45 and the sealing gasket 46, and the outer bushing 481 is inserted into the receiving cavity. During the movement, the limiting bracket 57 contacts the locking pin 54 at the other end of the bracket 51. The limiting bracket 57 presses the locking pin 54 through the guide chamfer, and the locking pin 54 compresses the spring 55. The spring 55 is deformed by compression. When the protective plate 47 moves into position, the locking pin 54 coincides with the through hole, the limiting bracket 57 stops applying pressure to the locking pin 54, the locking pin 54 stops compressing the spring 55, the spring 55 loses pressure and rebounds, pushing the locking pin 54 back to its original position. The locking pin 54 is inserted into the through hole and pushes the pressure block 510 out of the through hole. At this time, the protective plate 47 is locked in the closed state. Turn open the first protective valve on the air intake valve 484. After unscrewing the first protective cover 485, place it on the protective plate 47 using the magnet 486 and the magnetic suction piece 411; rotate the fixing sleeve 65 to remove the connector 64 from the threaded post 68, and then install the removed connector 64 on the air inlet valve 484 using the fixing sleeve 65. After completing the operation, open the second protective cover 610 to open the air inlet of the air pump 62, push the pressing sleeve 66, and the pressing sleeve 66 cooperates with the squeezing frame 67 to press the air pump 62. The air pump 62 injects air into the airbag formed by the outer bushing 481 and the flexible inner bushing 482 through the air outlet, the conduit 63 and the connector 64. The flexible inner bushing 482 expands under the action of air to fill and seal the gaps between the cables and clamp the cables. After the inflation operation is completed, disconnect the connector 64 and re-fix the connector 64 to the threaded post 68. After disconnecting the connector 64, remove the first protective cover 485 and reinstall it on the air inlet valve 484. Then, reinstall the second protective cover 610 on the air inlet of the air pump 62. When it is necessary to deflate the airbag and remove the aviation plug, unscrew the first protective cover 485 on the exhaust valve 483, and use a tool to open the valve core of the exhaust valve 483 to release the air.

[0033] After the cable connector 64 on the interface panel 2 is installed, the protective device 4 installed on the housing 1 covers the opening of the housing 1, thus isolating the interface panel 2 and the cable connector 64 from the external environment and placing them in a closed chamber. This design can effectively prevent rainwater, condensation and dust from entering, avoiding problems such as corrosion, water ingress, poor contact or insulation degradation at the interface, preventing equipment malfunction, communication interruption or abnormal telemetry and telecontrol data, and ensuring the reliable operation of the power distribution network automation system.

[0034] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
