Technical Field

[0001] The present application relates to the technical field of vacuum circuit breakers, and in particular to a digital deep-integrated outdoor high-voltage vacuum circuit breaker. Background Art

[0002] A vacuum circuit breaker is a high-voltage switchgear that uses a high vacuum environment as an insulating and arc-extinguishing medium. It is mainly used for the connection, disconnection and fault protection of circuits in power systems. Most vacuum circuit breakers are installed outdoors. Vacuum circuit breakers are usually electrically connected through aviation plug connectors, and electronic information is output through aviation plug connectors. With the development of the times, the transmission of electronic signals has great limitations. Therefore, some vacuum circuit breakers use digital units to convert the measured data into digital signals and then transmit them to the terminal.

[0003] In the related art, a vacuum circuit breaker includes a housing, and a digital unit is plugged into the housing.

[0004] Since the digital unit is directly exposed on the housing and the vacuum circuit breaker is usually installed outdoors, the digital unit is easily damaged by rain. Summary of the Invention

[0005] In order to improve the problem that digital units are easily damaged, the present application provides a digital deep-integrated outdoor high-voltage vacuum circuit breaker.

[0007] By adopting the above technical solution, the protective shell is installed on the protective base through fasteners, so that the protective base and the protective shell can protect the digital unit, so that the digital unit can be stably fixed to the plug, reducing damage to the digital unit caused by the outside world, and making the digital unit less likely to be damaged by rain; at the same time, the digital unit can convert the measured data into a digital signal, and transmit the digital signal to the terminal, so that the data transmitted by the digital signal is not easily distorted during the transmission process, making the data obtained by the terminal more accurate.

[0008] Optionally, the placement slot extends through one side of the protective base, and a through-hole is provided on the protective shell; when the protective shell is mounted on the protective base, the through-hole communicates with the opening through which the placement slot extends.

[0009] By adopting the above technical solution, the placement slot penetrates to one side of the protective base, and a perforation is opened on the protective shell, so that the perforation is connected to the opening through which the placement slot penetrates, so that the digital unit will not be completely covered by the protective base and the protective shell, thereby ensuring the reliability of digital signal transmission and the electromagnetic compatibility of the system.

[0010] Optionally, a waterproof block is provided in the placement groove, a groove is provided on the waterproof block, and the plug is located in the groove.

[0011] By adopting the above technical solution, the plug is set in the groove, so that the digitization unit can be inserted into the plug in the groove, and the waterproof block can provide waterproof protection for the digitization unit, reducing the damage to the digitization unit caused by moisture.

[0012] Optionally, a receiving groove is provided on the digitization unit, an elastic component is provided in the receiving groove, a fixing block is provided on the elastic component, a fixing hole for inserting the fixing block is provided in the placement groove, and the elastic component drives the fixing block to be inserted into the fixing hole.

[0013] By adopting the above technical solution, the elastic component drives the fixed block to move, so that the fixed block can be inserted into the fixing hole, thereby fixing the digitization unit and the protective base, so that the digitization unit can be fixed on the protective base, reducing the possibility of the digitization unit detaching from the protective base.

[0014] Optionally, a receiving hole connected to the receiving groove is provided on the digitization unit, a movable hole is provided on the fixed block, a movable inclined surface is provided on the hole wall of the movable hole, and the distance between the movable inclined surface and the receiving hole gradually increases along the direction from the digitization unit to the shell; when the fixed block is disengaged from the fixed hole, the movable hole is aligned with the receiving hole; when the fixed block is located in the fixed hole, the movable inclined surface is aligned with the receiving hole.

[0015] By adopting the above technical solution, the distance between the movable inclined surface and the accommodating hole is gradually increased along the direction from the digitizing unit to the shell. The staff can insert the tool into the accommodating hole and let the tool drive the fixed block to move through the movable inclined surface, so that the fixed block can be detached from the fixed hole, thereby unlocking the digitizing unit and the protective base, allowing the digitizing unit to be taken out of the placement slot, and realizing the maintenance of the digitizing unit.

[0016] Optionally, a limit spring is provided on the placement groove, a limit piece is provided on the limit spring, and the limit spring drives the limit piece to block the accommodating hole; when the digitization unit is inserted into the plug, the digitization unit abuts against the limit piece.

[0017] By adopting the above technical solution, the limit spring drives the limit part to move, so that the limit part can block the accommodating hole, making it impossible for outsiders to directly insert foreign objects into the accommodating hole, reducing the possibility of separation between the digital unit and the protective base, and allowing the limit part to protect the digital unit more stably; at the same time, the digital unit abuts the limit part, so that the force between the digital unit and the plug can be shared by the limit part, reducing the possibility of damage between the plug and the digital unit.

[0018] Optionally, a sealing strip is provided on the protective shell, the sealing strip is arranged in a V-shape, the sealing strip protrudes in a direction away from the ground, and the sealing strip abuts the protective shell and the protective base.

[0019] By adopting the above technical solution, the sealing strip can abut against the protective shell and the protective base, so that the sealing strip can reduce the possibility of rainwater entering through the gap between the protective shell and the protective base; at the same time, the sealing strip is set in a V-shape, so that the sealing strip bulges away from the ground, so that rainwater can move toward the ground along the V-shape of the sealing strip, reducing the accumulation of rainwater on the sealing strip, so that the sealing strip is not easily damaged by excessive soaking in rainwater.

[0020] Optionally, a rotating bar is rotatably connected to the protective shell, and the sealing strip is slidably connected to the protective shell. One end of the rotating bar is located on the moving path of the limiting member, and the other end of the rotating bar abuts the sealing strip; when the limiting member blocks the accommodating hole, the rotating bar drives the sealing strip to squeeze the protective base.

[0021] By adopting the above technical solution, when the limiting member blocks the accommodating hole, since one end of the rotating bar is located on the moving path of the limiting member, the other end of the rotating bar abuts the sealing strip, and the limiting member drives the rotating bar to rotate, so that the other end of the rotating bar abuts the sealing strip, so that the sealing strip can squeeze the protective base, further increasing the protection of the sealing strip to the protective base and the protective shell.

[0022] Optionally, the limiting component includes a limiting block and a limiting spring, the limiting spring is arranged on the limiting block, the limiting block is arranged on the limiting spring, the limiting spring is bent in the direction away from the placement groove, and a limiting groove for inserting the limiting spring is provided on the protective shell; when the limiting spring is inserted into the limiting groove, the limiting block blocks the accommodating hole, and the sealing strip squeezes the protective base.

[0023] By adopting the above technical solution, the limit block is set on the limit spring, so that the limit block can block the accommodating hole. Since the limit spring is set on the limit block, when the limit block does not block the accommodating hole, the staff still needs to deform the limit spring before inserting the tool into the accommodating hole, reducing the possibility that the limit block fails to block the accommodating hole due to the sliding of the vacuum circuit breaker; the limit spring is inserted into the limit groove, so that the limit spring can be fixed on the protective shell, so that the limit spring can limit the rotating bar, reducing the possibility of the rotating bar rotating on the protective shell, allowing the rotating bar to stably squeeze the sealing strip, and allowing the sealing strip to squeeze the protective base.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The protective shell is installed on the protective base through fasteners, so that the protective base and the protective shell can protect the digital unit, so that the digital unit can be stably fixed to the plug, reducing damage to the digital unit caused by the outside world, and making the digital unit less likely to be damaged by rain; at the same time, the digital unit can convert the measured data into digital signals, and transmit the digital signals to the terminal, making the digital signal transmission faster and more accurate.

[0025] 2. The limit block is set on the limit spring, so that the limit block can block the accommodating hole. Since the limit spring is set on the limit block, when the limit block does not block the accommodating hole, the staff still needs to deform the limit spring to insert the tool into the accommodating hole, reducing the possibility that the limit block fails to block the accommodating hole due to the sliding of the vacuum circuit breaker; the limit spring is inserted into the limit groove, so that the limit spring can be fixed on the protective shell, so that the limit spring can limit the rotating bar, reducing the possibility of the rotating bar rotating on the protective shell, allowing the rotating bar to stably squeeze the sealing strip, and allowing the sealing strip to squeeze the protective base.

[0028] The following is combined with Figure 1-8 This application is described in further detail.

[0029] Example 1 This embodiment discloses a digital deep fusion outdoor high voltage vacuum circuit breaker. Figure 1 and Figure 2 A digital deep-fusion outdoor high-voltage vacuum circuit breaker includes a shell 1, a protective base 2 is fixedly connected to the shell 1, a placement groove 21 is opened on the protective base 2, and the placement groove 21 passes through the protective base 2 toward the ground.

[0030] Reference Figure 3 The housing 1 is provided with a digitizing unit 11, which can be inserted into a placement slot 21. A waterproof block 22 is fixedly connected to the wall of the placement slot 21, and the waterproof block 22 is made of rubber. A groove 221 is provided on the surface of the waterproof block 22 facing the ground, and a plug 222 is fixedly connected to the groove 221. The plug 222 and the digitizing unit 11 cooperate with each other to achieve electrical connection between the digitizing unit 11 and the vacuum circuit breaker. The digitizing unit 11 can process the data measured by the vacuum circuit breaker and convert it into a digital signal to transmit to the terminal.

[0031] Reference Figure 3 The protective base 2 has two placement holes 23 on its surface. Both placement holes 23 are connected to the placement slot 21 and are located on opposite sides of the placement slot 21. When the digitizing unit 11 is inserted into the plug 222, the operator can hold the digitizing unit 11 through the two placement holes 23.

[0032] Reference Figure 4 A receiving groove 12 is provided on the surface of the digitizing unit 11, and an elastic component 121 is provided on the bottom wall of the receiving groove 12. The elastic component 121 includes an elastic spring. One end of the elastic spring is fixedly connected to the bottom wall of the receiving groove 12, and the other end of the elastic spring is fixedly connected to a fixing block 122, and the elastic spring drives the fixing block 122 to protrude from the receiving groove 12. The fixing block 122 and the elastic spring can be completely located in the receiving groove 12, so that the digitizing unit 11 can be inserted into the placement groove 21. A fixing hole 231 for inserting the fixing block 122 is provided on the groove wall of the placement groove 21. When the digitizing unit 11 is inserted into the plug 222, the fixing block 122 is located in the fixing hole 231, thereby realizing the mutual fixation of the digitizing unit 11 and the protective base 2.

[0033] Reference Figure 4 The digitizing unit 11 has a receiving hole 123 on its surface near the ground, connected to the receiving groove 12. The receiving hole 123 is for inserting tools. The fixed block 122 has a movable hole 124 on its surface for inserting tools. A movable inclined surface 125 is provided on the wall of the movable hole 124 near the elastic spring. The distance between the movable inclined surface 125 and the receiving hole 123 gradually increases along the direction from the digitizing unit 11 to the housing 1. When the fixed block 122 is located in the fixing hole 231, the movable hole 124 is aligned with the receiving hole 123. At this time, the staff can insert a tool into the movable hole 124 and the receiving hole 123 to disengage the fixed block 122 from the fixing hole 231, thereby unlocking the digitizing unit 11.

[0034] Reference Figure 4 The protective base 2 is provided with a protective housing 3, which is used to block the opening of the placement slot 21. A through-hole 31 is formed on the surface of the protective housing 3. When the protective housing 3 is mounted on the protective base 2, the through-hole 31 communicates with the opening in the direction through which the placement slot 21 passes, allowing the signal from the digitizing unit 11 to be transmitted through the through-hole 31.

[0035] Reference Figure 1 and Figure 3 The protective housing 3 is provided with a fastener 32 comprising two fastening blocks 321 and fastening bolts 322. The two fastening blocks 321 are fixedly connected to opposite sides of the protective housing 3. The fastening blocks 321 have fastening holes 323 for inserting the fastening bolts 322, and the housing 1 has fastening slots 324 for threading the fastening bolts 322. When the fastening bolts 322 are inserted into the fastening holes 323 and threaded into the fastening slots 324, the protective base 2 and protective housing 3 are fixed to each other, effectively protecting the digitizing unit 11.

[0036] The implementation principle of Example 1 is as follows: the staff first inserts the tool into the receiving hole 123, and allows the tool to move the fixing block 122 through the movable inclined surface 125, so that the fixing block 122 disengages from the fixing hole 231, thereby releasing the lock of the digitizing unit 11 and the protective base 2.

[0037] Example 2 Reference Figure 5 and Figure 6 This embodiment differs from Embodiment 1 in that a receiving groove 24 is defined on the surface of the housing 1, and a limit spring 241 is fixedly connected to the bottom wall of the receiving groove 24. A limit member 242 is provided on the surface of the limit spring 241 away from the bottom wall of the receiving groove 24, and the limit spring 241 drives the limit member 242 to protrude out of the receiving groove 24.

[0038] Reference Figure 6 The limiting member 242 includes a limiting block 243 and a limiting spring 244. The limiting block 243 is fixedly connected to the surface of the limiting spring 241 away from the bottom wall of the receiving groove 24, and the limiting spring 244 is fixedly connected to the surface of the limiting block 243 away from the limiting spring 241. The limiting spring 244 can bend toward the ground. The limiting spring 241 drives the limiting block 243 to protrude from the receiving groove 24.

[0039] Reference Figure 5 and Figure 6 When the digitizing unit 11 is inserted into the plug 222, the digitizing unit 11 can abut against the stopper 243. When the staff pushes the stopper 243 to locate in the receiving groove 24, the stopper spring 244 still blocks the receiving hole 123. The staff needs to pull the stopper spring 244 to insert the tool into the receiving hole 123.

[0040] Reference Figure 7 A support frame 33 is fixedly connected to the protective shell 3, and a rotating bar 331 is rotatably connected to the support frame 33. The rotating bar 331 can rotate toward or away from the protective base 2, and the rotation path of one end of the rotating bar 331 intersects with the movement path of the limiting spring 244. A sealing strip 332 is slidably connected to the surface of the protective shell 3, and the sealing strip 332 is arranged in a V shape. The sliding path of the sealing strip 332 intersects with the rotation path of the other end of the rotating bar 331. The sealing strip 332 protrudes away from the ground so that rainwater can flow down along the V-shaped arrangement of the sealing strip 332. A limiting groove 333 is provided on the protective shell 3 for the limiting spring 244 to be inserted. When the limiting spring 244 is inserted into the limiting groove 333, the limiting spring 244 can stably abut the rotating bar 331, allowing the rotating bar 331 to smoothly squeeze the sealing strip 332.

[0041] Reference Figure 7 and Figure 8A rotating bevel 334 is formed on the end of the rotating bar 331 away from the ground. The distance between the rotating bevel 334 and the protective base 2 gradually decreases along the direction from the protective housing 3 to the ground. The rotating bevel 334 is used to abut the sealing strip 332. When the rotating bevel 334 abuts the sealing strip 332, the rotating bevel 334 pushes the sealing strip 332 to deform, allowing the sealing strip 332 to abut the protective base 2, thereby reducing the gap between the protective base 2 and the protective housing 3 and preventing rainwater from entering between the protective base 2 and the protective housing 3.

[0042] Reference Figure 6 、 Figure 7 and Figure 8 When the limiting block 243 blocks the opening of the accommodating hole 123, the limiting spring piece 244 is inserted into the limiting groove 333, allowing the limiting spring piece 244 to drive the rotating bar 331 to rotate, so that the rotating bar 331 can push the sealing strip 332 to move, and the sealing strip 332 can squeeze the protective base 2 and the protective shell 3, so that the sealing strip 332 can stably limit the flow of rainwater between the protective shell 3 and the protective base 2.

[0043] The implementation principle of Example 2 is as follows: the limiting spring 241 pushes the limiting block 243 to move, so that the limiting block 243 blocks the accommodating hole 123, and the limiting spring piece 244 is inserted into the limiting groove 333, so that the limiting spring piece 244 rotates the rotating bar 331, and the rotating bar 331 squeezes the sealing strip 332, so that the sealing strip 332 can limit rainwater from flowing into the gap between the protective base 2 and the protective shell 3.
