Description

Technical Field

[0001] This application relates to the technical field of vacuum circuit breakers, and in particular to an outdoor vacuum circuit breaker. Background Technology

[0002] A vacuum circuit breaker is a type of high-voltage switchgear. Its working principle is based on the characteristics of an electric arc in a vacuum. When current flows through the contacts, if the contacts separate, an electric arc is formed between them. Because gas molecules are extremely scarce in a vacuum environment, the arc is difficult to sustain and can be extinguished quickly.

[0003] The existing announcement number CN205177698U, entitled "A Permanent Magnet Outdoor Vacuum Circuit Breaker," includes a circuit breaker body, a disconnecting switch, and a switching assembly for opening and closing the circuit breaker body and the disconnecting switch. The switching assembly includes a switch piece, which has a hinged end that is hinged to the circuit breaker body and a connecting end. The connecting end is threadedly connected to or snapped with an abutment. The abutment has an abutment part for abutting against the disconnecting switch. The abutment is connected to the connecting end by threading or snapping. The overall effect is a detachable and fixed connection. When the abutment part on the abutment is severely worn, the operator can directly remove the abutment from the connecting end and replace the abutment. This avoids the drawback of needing to replace the switching assembly on traditional circuit breakers, significantly reduces the time spent on disassembly and assembly, reduces the waste of necessary materials, and lowers the operating cost.

[0004] Regarding the aforementioned technologies, the inventors discovered that the opening and closing method of the vacuum circuit breaker uses a gate plate for opening and closing, with the gate plate end hinged. After prolonged opening and closing, the hinged column wears down, causing the gate plate to have a misalignment during opening and closing, which in turn leads to misalignment when the gate plate is closed, resulting in a decrease in the opening and closing accuracy of the vacuum circuit breaker. Utility Model Content

[0005] In order to overcome the problem that the existing vacuum circuit breaker uses a gate plate for opening and closing, and the gate plate is hinged at the end, the hinged column wears after a long period of opening and closing, which leads to the gate plate having a misalignment when opening and closing, and thus the gate plate closing is misaligned, resulting in a decrease in the opening and closing accuracy of the vacuum circuit breaker, this application provides an outdoor vacuum circuit breaker.

[0006] The outdoor vacuum circuit breaker provided in this application adopts the following technical solution:

[0007] An outdoor vacuum circuit breaker includes a vacuum circuit breaker body, an upper closing component, and a lower closing component. A grounding hole seat is horizontally fixed to the upper part of the vacuum circuit breaker body, and the upper closing component is mounted on the grounding hole seat. The upper closing component includes a conductive plate, which is horizontally assembled on the grounding hole seat. An adjusting screw is horizontally fixed to one end of the conductive plate away from the grounding hole seat. A connecting component is mounted on the adjusting screw. The connecting component includes a screw barrel seat, on which a screw shell is threadedly assembled. A grounding plate is vertically fixed to the top surface of the screw shell, and a connecting cup is vertically assembled to the bottom end of the screw shell. A cup seat is fixed inside the connecting cup. The lower closing component includes a bracket, on which a connecting plate is horizontally mounted. A terminal post is vertically fixed to the top surface of the connecting plate, and the connecting post presses against the cup seat.

[0008] By adopting the above technical solution, during use, the upper bracket of the lower assembly moves vertically, which drives the docking post on the top surface of the docking plate to move vertically. This causes the docking post to insert into the bowl seat of the docking bowl on the upper assembly. Thus, the docking post on the docking component is vertically inserted into the bowl seat of the docking bowl. This insertion and connection method facilitates the quick completion of power connection and disconnection requirements, avoids the problem of deterioration in the opening and closing accuracy of hinged joints, improves the opening and closing accuracy, and reduces the wear of the docking bowl and bowl seat, thereby extending the service life of the docking bowl and bowl seat.

[0009] Optionally, a rod is vertically fixed on the outer wall of the vacuum circuit breaker body, and a screw-hole sliding plate is vertically slidably assembled on the rod, and the screw-hole sliding plate is fixedly connected to the end of the bracket.

[0010] By adopting the above technical solution, a screw-hole sliding plate is vertically slidably assembled on the pole, which drives the bracket to move vertically, so that the docking post on the docking part is vertically inserted into the bowl seat of the docking bowl to perform opening and closing power supply operation.

[0011] Optionally, a mating screw is vertically rotatably connected to the rod frame, and a mating motor is vertically fixed on the bottom surface of the rod frame. The output end of the mating motor is fixed on the bottom end of the mating screw, and the thread of the mating screw is threaded through and assembled in the screw hole slide plate.

[0012] By adopting the above technical solution, the starting motor drives the rotating screw to rotate, and the threaded drive screw hole slide plate slides vertically on the rod frame, which facilitates vertical opening and closing control of power supply.

[0013] Optionally, a ceramic column is vertically installed between the bracket and the mating plate, and bolts are vertically fixed at both ends of the ceramic column. The bolt threads at both ends of the ceramic column are assembled on the adjacent end faces of the bracket and the mating plate.

[0014] By adopting the above technical solution, the bracket and the docking plate are insulated and supported by ceramic columns. The bolts at both ends of the ceramic columns are threaded onto the adjacent end faces of the bracket and the docking plate, connecting the bracket and the docking plate into a whole.

[0015] Optionally, a connecting plate is fixed to the other end of the conductive plate, and the connecting plate is connected to the conductive plate by screws.

[0016] By adopting the above technical solution, the connecting hole plate at the end of the conductive plate is fixedly connected to the conductive plate by screws, which facilitates the electrical connection between the conductive plate and the connecting hole plate.

[0017] Optionally, a screw tube is horizontally fixed at one end of the screw barrel seat, and the screw tube is threadedly assembled onto the adjusting screw.

[0018] By adopting the above technical solution, the threaded assembly of the screw tube on the docking part and the adjusting screw during installation facilitates the lateral adjustment of the distance between the docking part and the vacuum circuit breaker body.

[0019] Optionally, a stud is vertically fixed on the top surface of the mating bowl, and the stud thread is assembled into the screw shell.

[0020] By adopting the above technical solution, the stud on the docking bowl is connected to the threaded assembly of the shell, which facilitates the later disassembly and replacement of the docking bowl.

[0021] Optionally, a bracket is vertically fixed on the screw base, and a spool is vertically fixed through the top surface of the bracket, while a rainproof shell is vertically fixed through the bottom surface of the spool.

[0022] By adopting the above technical solution, the bracket on the screw base guides the cable through the spool, and the rainproof shell on the spool is used to prevent water from wetting the contact plate.

[0023] In summary, this application includes at least one of the following beneficial technical effects: during use, the upper bracket of the lower assembly moves vertically, causing the docking post on the top surface of the docking plate to move vertically, and causing the docking post to insert into the bowl seat of the docking bowl of the upper assembly. Thus, the docking post on the docking piece is vertically inserted into the bowl seat of the docking bowl. The insertion and engagement method facilitates the quick completion of power connection and power disconnection requirements, avoids the problem of deterioration in hinge opening and closing accuracy, improves opening and closing accuracy, and at the same time reduces wear on the docking bowl and bowl seat, thereby increasing the service life of the docking bowl and bowl seat.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses an outdoor vacuum circuit breaker. (Refer to...)
