Description

Technical Field

[0001] This application relates to the technical field of vacuum circuit breakers, and in particular to a digitally integrated outdoor high-voltage vacuum circuit breaker. Background Technology

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

[0003] In related technologies, vacuum circuit breakers include a housing with a digital unit plugged into it.

[0004] Because the digital unit is directly exposed to the housing, and vacuum circuit breakers are typically installed outdoors, the digital unit is susceptible to damage from rain. Summary of the Invention

[0005] To address the issue of susceptibility to damage in digital units, this application provides a digitally integrated outdoor high-voltage vacuum circuit breaker.

[0006] This application provides a digitally integrated outdoor high-voltage vacuum circuit breaker, which adopts the following technical solution:

[0007] A digital deep-integrated outdoor high-voltage vacuum circuit breaker includes a housing, a protective base on the housing, a placement slot on the protective base, a plug inside the placement slot, a digital unit on the protective base for inserting the plug, a protective outer shell on the housing for sealing the opening of the placement slot, and fasteners on the protective outer shell for fixing the protective outer shell and the protective base together.

[0008] By adopting the above technical solution, the protective shell is installed on the protective base with fasteners, so that the protective base and protective shell can protect the digital unit, so that the digital unit can be stably fixed to the plug, reducing the damage caused by the outside world to the digital unit and making the digital unit less susceptible to damage from rain; at the same time, the digital unit can convert the measured data into digital signals and transmit the digital signals to the terminal, so that the data transmitted by the digital signals is not easily distorted during the transmission process, making the data obtained by the terminal more accurate.

[0009] Optionally, the placement slot extends to one side of the protective base, and the protective housing has a through hole; when the protective housing is installed on the protective base, the through hole connects to the opening through which the placement slot extends.

[0010] By adopting the above technical solution, the placement slot extends through to one side of the protective base, and the protective shell has a perforation that connects to the opening of the placement slot. This ensures that the digital unit is not completely covered by the protective base and the protective shell, thus guaranteeing the reliability of digital signal transmission and the electromagnetic compatibility of the system.

[0011] Optionally, a waterproof block is provided in the placement slot, and a groove is formed on the waterproof block, with the plug located in the groove.

[0012] By adopting the above technical solution, the plug is placed in the groove, allowing the digitizing unit to be inserted into the plug within the groove. This enables the waterproof block to provide waterproof protection for the digitizing unit, reducing damage to the digitizing unit from moisture.

[0013] Optionally, the digitizing unit has a receiving groove, the receiving groove has an elastic component, the elastic component has a fixing block, the placement groove has a fixing hole for the fixing block to be inserted, and the elastic component drives the fixing block to be inserted into the fixing hole.

[0014] By adopting the above technical solution, the fixed block is moved by the elastic component, allowing the fixed block to be inserted into the fixed hole, thereby fixing the digital unit and the protective base. This ensures that the digital unit is fixed on the protective base, reducing the possibility of the digital unit detaching from the protective base.

[0015] Optionally, the digitizing unit has a receiving hole that connects to the receiving groove, the fixing block has a moving hole, and the wall of the moving hole has a moving inclined surface. The distance between the moving inclined surface and the receiving hole gradually increases along the direction from the digitizing unit to the housing. When the fixing block is disengaged from the fixing hole, the moving hole aligns with the receiving hole. When the fixing block is located inside the fixing hole, the moving inclined surface aligns with the receiving hole.

[0016] By adopting the above technical solution, the distance between the moving inclined plane and the receiving hole gradually increases along the direction from the digitizing unit to the housing. The operator can insert a tool into the receiving hole and let the tool move the fixing block through the moving inclined plane, so that the fixing block can be disengaged from the fixing 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.

[0017] Optionally, the placement slot is provided with a limiting spring, and the limiting spring is provided with a limiting member. The limiting spring drives the limiting member to block the receiving hole; when the digitizing unit is inserted into the plug, the digitizing unit abuts against the limiting member.

[0018] By adopting the above technical solution, the limiting spring drives the limiting component to move, allowing the limiting component to block the receiving hole, preventing external personnel from directly inserting foreign objects into the receiving hole, reducing the possibility of the digital unit and the protective base separating from each other, and allowing the limiting component to more stably protect the digital unit; at the same time, the digital unit abuts against the limiting component, so that the force between the digital unit and the plug can be distributed to the limiting component, reducing the possibility of damage between the plug and the digital unit.

[0019] Optionally, the protective housing is provided with a sealing strip, which is V-shaped and protrudes in a direction away from the ground. The sealing strip abuts against the protective housing and the protective base.

[0020] By adopting the above technical solution, the sealing strip can abut against the protective shell and the protective base, thereby reducing 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 protrudes in the direction away from the ground, allowing rainwater to move along the V-shape of the sealing strip towards the ground, reducing the accumulation of rainwater at the sealing strip, thus making the sealing strip less likely to be damaged by excessive soaking in rainwater.

[0021] Optionally, a rotating strip is rotatably connected to the protective housing, and a sealing strip is slidably connected to the protective housing. One end of the rotating strip is located on the moving path of the limiting member, and the other end of the rotating strip abuts against the sealing strip. When the limiting member blocks the receiving hole, the rotating strip drives the sealing strip to squeeze the protective base.

[0022] By adopting the above technical solution, when the limiting member blocks the receiving hole, since one end of the rotating strip is located on the moving path of the limiting member and the other end of the rotating strip abuts against the sealing strip, the limiting member drives the rotating strip to rotate, so that the other end of the rotating strip abuts against the sealing strip, allowing the sealing strip to squeeze the protective base, further increasing the protection of the protective base and the protective shell by the sealing strip.

[0023] Optionally, the limiting component includes a limiting block and a limiting spring. The limiting spring is disposed on the limiting block, and the limiting block is disposed on the limiting spring. The limiting spring is bent away from the placement groove. The protective housing has a limiting groove for the limiting spring to be inserted. When the limiting spring is inserted into the limiting groove, the limiting block blocks the receiving hole, and the sealing strip squeezes the protective base.

[0024] By adopting the above technical solution, the limiting block is set on the limiting spring, allowing the limiting block to seal the receiving hole. Since the limiting spring is set on the limiting block, even if the limiting block does not seal the receiving hole, the operator still needs to deform the limiting spring to insert the tool into the receiving hole, reducing the possibility that the limiting block will not seal the receiving hole due to the slippage of the vacuum circuit breaker. By inserting the limiting spring into the limiting groove, the limiting spring can be fixed on the protective shell, thereby limiting the rotating strip, reducing the possibility of the rotating strip rotating on the protective shell, allowing the rotating strip to stably squeeze the sealing strip, and allowing the sealing strip to squeeze the protective base.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The protective housing is fastened to the protective base, which protects the digitizing unit and ensures stable fixation of the digitizing unit to the plug, reducing external damage to the digitizing unit and making it less susceptible to damage from rain. At the same time, the digitizing 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.

[0027] 2. By setting a limiting block on the limiting spring, the limiting block can seal the receiving hole. Since the limiting spring is set on the limiting block, even if the limiting block does not seal the receiving hole, the operator still needs to deform the limiting spring to insert the tool into the receiving hole, reducing the possibility that the limiting block will not seal the receiving hole due to the slippage of the vacuum circuit breaker. By inserting the limiting spring into the limiting groove, the limiting spring can be fixed on the protective shell, thereby limiting the rotating strip, reducing the possibility of the rotating strip rotating on the protective shell, allowing the rotating strip to stably squeeze the sealing strip, and allowing the sealing strip to squeeze the protective base.

[0037] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0038] Example 1

[0039] This embodiment discloses a digitally integrated outdoor high-voltage vacuum circuit breaker. (Refer to...) Figure 1 and Figure 2 A digital deep-integrated outdoor high-voltage vacuum circuit breaker includes a housing 1, a protective base 2 fixedly connected to the housing 1, and a placement groove 21 provided on the protective base 2, the placement groove 21 extending through the protective base 2 towards the ground.

[0040] Reference Figure 3 The housing 1 is equipped with a digitizing unit 11, which can be inserted into a placement slot 21. A waterproof block 22, made of rubber, is fixedly connected to the wall of the placement slot 21. A groove 221 is formed on the surface of the waterproof block 22 facing the ground, and a plug 222 is fixedly connected in the groove 221. The plug 222 and the digitizing unit 11 cooperate to realize the 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 for transmission to the terminal.

[0041] Reference Figure 3The protective base 2 has two placement holes 23 on its surface, both of which 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.

[0042] Reference Figure 4 A receiving groove 12 is formed on the surface of the digitizing unit 11. An elastic component 121, including an elastic spring, is provided on the bottom wall of the receiving groove 12. 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. The elastic spring drives the fixing block 122 to protrude out of the receiving groove 12. The fixing block 122 and the elastic spring can be completely located within the receiving groove 12, so that the digitizing unit 11 can be inserted into the placement groove 21. A fixing hole 231 is formed on the groove wall of the placement groove 21 for the fixing block 122 to be inserted. When the digitizing unit 11 is inserted into the plug 222, the fixing block 122 is located in the fixing hole 231, realizing the mutual fixation of the digitizing unit 11 and the protective base 2.

[0043] Reference Figure 4 The digitizing unit 11 has a receiving hole 123 on its surface near the ground, which connects to the receiving groove 12 for inserting tools. The fixing block 122 has a moving hole 124 for inserting tools. A moving inclined surface 125 is formed on the wall of the moving hole 124 near the elastic spring. The distance between the moving inclined surface 125 and the receiving hole 123 gradually increases along the direction from the digitizing unit 11 to the housing 1. When the fixing block 122 is located within the fixing hole 231, the moving hole 124 aligns with the receiving hole 123. At this time, the operator can insert a tool into the moving hole 124 and the receiving hole 123 to disengage the fixing block 122 from the fixing hole 231, thus unlocking the digitizing unit 11.

[0044] Reference Figure 4 The protective base 2 is provided with a protective shell 3, which is used to seal the opening of the placement slot 21, and a through hole 31 is provided on the surface of the protective shell 3. When the protective shell 3 is installed on the protective base 2, the through hole 31 connects to the opening of the placement slot 21 in the through direction, and the signal of the digitizing unit 11 can be transmitted from the through hole 31.

[0045] Reference Figure 1 and Figure 3The protective housing 3 is equipped with fasteners 32, which include 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 the fastening bolts 322 to be inserted into, and the housing 1 has fastening grooves 324 for the fastening bolts 322 to be threaded into the fastening grooves 324. When the fastening bolts 322 are inserted into the fastening holes 323 and threaded into the fastening grooves 324, the protective base 2 and the protective housing 3 are fixed to each other, thus protecting the digital unit 11.

[0046] The implementation principle of Example 1 is as follows: The operator first inserts the tool into the receiving hole 123, and the tool moves the fixing block 122 by moving the inclined plane 125, so that the fixing block 122 is disengaged from the fixing hole 231, thereby releasing the locking of the digital unit 11 and the protective base 2.

[0047] Example 2

[0048] Reference Figure 5 and Figure 6 The difference between this embodiment and Embodiment 1 is that a receiving groove 24 is formed on the surface of the housing 1, and a limiting spring 241 is fixedly connected to the bottom wall of the receiving groove 24. A limiting member 242 is provided on the surface of the limiting spring 241 away from the bottom wall of the receiving groove 24, and the limiting spring 241 drives the limiting member 242 to protrude out of the receiving groove 24.

[0049] 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 be bent towards the ground. The limiting spring 241 drives the limiting block 243 to protrude out of the receiving groove 24.

[0050] 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 limiting block 243. When the operator pushes the limiting block 243 into the receiving groove 24, the limiting spring 244 still blocks the receiving hole 123, and the operator needs to pull the limiting spring 244 to allow the tool to be inserted into the receiving hole 123.

[0051] Reference Figure 7A support frame 33 is fixedly connected inside the protective shell 3. A rotating strip 331 is rotatably connected to the support frame 33. The rotating strip 331 can rotate towards or away from the protective base 2, and the rotation path of one end of the rotating strip 331 intersects the movement path of the limiting spring 244. A sealing strip 332 is slidably connected to the surface of the protective shell 3. The sealing strip 332 is V-shaped. The sliding path of the sealing strip 332 intersects the rotation path of the other end of the rotating strip 331. The sealing strip 332 protrudes away from the ground so that rainwater can flow down along the V-shape 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 against the rotating strip 331, allowing the rotating strip 331 to smoothly compress the sealing strip 332.

[0052] Reference Figure 7 and Figure 8 A rotating inclined surface 334 is provided on the end of the rotating strip 331 away from the ground. The distance between the rotating inclined surface 334 and the protective base 2 gradually decreases along the direction from the protective shell 3 to the ground, and the rotating inclined surface 334 is used to abut against the sealing strip 332. When the rotating inclined surface 334 abuts against the sealing strip 332, the rotating inclined surface 334 pushes the sealing strip 332 to deform, allowing the sealing strip 332 to abut against the protective base 2, thereby reducing the gap between the protective base 2 and the protective shell 3, making it difficult for rainwater to enter between the protective base 2 and the protective shell 3.

[0053] Reference Figure 6 , Figure 7 and Figure 8 When the limiting block 243 blocks the opening of the receiving hole 123, the limiting spring 244 is inserted into the limiting groove 333, causing the limiting spring 244 to drive the rotating bar 331 to rotate, so that the rotating bar 331 can push the sealing bar 332 to move. The sealing bar 332 can squeeze the protective base 2 and the protective shell 3, so that the sealing bar 332 can stably restrict the flow of rainwater between the protective shell 3 and the protective base 2.

[0054] 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 receiving hole 123, and the limiting spring 244 is inserted into the limiting groove 333, so that the limiting spring 244 rotates the rotating bar 331. The rotating bar 331 squeezes the sealing strip 332, so that the sealing strip 332 can restrict rainwater from flowing in from the gap between the protective base 2 and the protective shell 3.
