Description

Technical Field

[0001] The present invention relates to the technical field of ultra-high voltage circuit breakers, and in particular to an ultra-high voltage circuit breaker. Background Art

[0002] It is the most complex and important electrical appliance in high-voltage equipment. Under the specified conditions of use, it can meet the load current under normal operating conditions. In the case of a short-circuit fault, it can automatically cut off the short-circuit current under the action of the relay protection device. In the high-voltage power supply and distribution system, when the short-circuit current is cut off, a strong arc will be generated. Therefore, the UHV circuit breaker has a reliable arc extinguishing device. The UHV circuit breaker is an electrical appliance that can achieve dual functions of control and protection. It is widely used in power plants, substations, switch stations and power lines of the power system;

[0003] At present, when the circuit breaker is installed on the electric pole, the mounting frame and the circuit breaker are fixedly connected. If the position of the circuit breaker is to be moved, the circuit breaker can only be disassembled, then moved, and finally fixed. Since the circuit breaker is heavy, it is difficult to move, which greatly increases the labor cost. In addition, after moving, it needs to be re-drilled and fixed, which greatly reduces the installation efficiency.

[0004] For this purpose, the utility model with the announcement number CN215869195U specifically discloses a UHV circuit breaker. When in use, the fixing bolts are loosened to loosen the movable seat and the mounting frame. Then, the sliding mechanism is used to slide the fixed seat and the movable seat along the mounting frame, so as to facilitate the movement of the circuit breaker and the circuit breaker terminal to connect with external wires and equipment. Then, the fixing bolts are tightened. In summary, not only the labor cost is saved, but also the installation efficiency is greatly improved.

[0005] During use, the device mainly wraps and fixes the utility pole by connecting the studs in conjunction with the fixing blocks and the supporting blocks. During use, the contact area with the utility pole is small, and the concentrated force can easily cause deformation of the connection. Secondly, due to the heavy size of the equipment, the heavy equipment lifting device is often lifted during installation. During the actual installation process, it is difficult to accurately correspond to the hole positions where the connecting studs are installed, which reduces the installation efficiency of the equipment.

[0006] To this end, a UHV circuit breaker is proposed. Summary of the invention

[0038] The fixing mechanism 3 includes a semicircular card plate 1 31 and a card plate 2 32 of the same size and structure, and connecting ear plates 34 are vertically fixed to the adjacent ends of the card plate 1 31 and the card plate 2 32, and a card box 35 is arranged on the outside of the two connecting ear plates 34, and a connecting groove 38 corresponding to the connecting ear plate 34 is opened in the card box 35, and the card box 35 is plugged into the outside of the connecting ear plate 34 through the connecting groove 38.

[0039] Specifically, an inner lining tooth plate 33 is provided inside the second card plate 32, and a guide column 322 is symmetrically fixed outside the inner lining tooth plate 33, and the guide column 322 passes through the second card plate 32 and is movably connected to the second card plate 32. A movable groove 321 is opened at the outer position of the second card plate 32 corresponding to the inner lining tooth plate 33, and the right-angle plate 5 corresponds to the movable groove 321. Teeth are fixed on the vertical surface of the right-angle plate 5 and the outer surface of the movable groove 321 of the inner lining tooth plate 33, and the right-angle plate 5 and the inner lining tooth plate 33 are meshingly connected.

[0040] By adopting the above technical solution, first, the right-angle plate 5 is screwed and installed and fixed to the base 2, and the vertical surface with teeth on one side of the right-angle plate 5 is engaged with the tooth groove in the movable groove 321 and meshed with the tooth groove at the corresponding position on the surface of the inner lining plate. Then, the base 2 and the second card plate 32 fixed on the base 2 are placed at a suitable height on the surface of the electric pole 6, and then the card plate 1 31 is placed on the other side of the electric pole 6. The card plate 1 31 needs to correspond to the card plate 2 32. Then the user takes the card box 35, and inserts the connecting groove 38 on the surface of the card box 35 and the connecting ear plate 34 fixed at the adjacent ends of the card plate 1 31 and the card plate 2 32 into the connecting groove 38 in the card box 35. At this time, the preliminary fixation of the card plate 1 31 and the card plate 2 32 is completed.

[0041] Specifically, a semicircular docking plate 314 is fixed to the top of the clamp plate 1 31 and the clamp plate 2 32, and a semicircular clamp 1 311 and a clamp 2 312 are respectively arranged on the outside of the docking plate 314, and the clamp 1 311 and the clamp 2 312 form a circular clamp wrapped around the outside of the docking plate 314, and plug-in blocks 315 are fixed to both ends of the clamp 1 311, and plug-in grooves 317 are provided at both ends of the clamp 2 312. The plug-in block 315 is located inside the plug-in groove 317 and is movably connected, and a half groove 1 316 and a half groove 2 318 of a rectangular structure are respectively provided on the lower sides of the adjacent ends of the clamp 1 311 and the clamp 2 312, and a docking block 36 of a rectangular structure is fixed to the top of the card box 35, and the rectangular hole formed by the combination of the half groove 1 316 and the half groove 2 318 matches the docking block 36.

[0042] By adopting the above technical solution, a card board 31 is then placed on the other side of the electric pole 6. Card board 31 needs to correspond to card board 2 32. Then the user takes the card box 35, and inserts the connecting groove 38 on the surface of the card box 35 and the connecting ear plate 34 fixed at the adjacent ends of card board 1 31 and card board 2 32 into the connecting groove 38 in the card box 35. At this time, the preliminary fixation of card board 1 31 and card board 2 32 is completed.

[0043] Specifically, a connecting column 37 is fixed on the top of the docking block 36 , and a wedge-shaped groove 319 matching the connecting column 37 is formed at a position corresponding to the connecting column 37 in the plug-in block 315 and the plug-in slot 317 .

[0044] By adopting the above technical solution, the connecting column 37 on the docking block 36 is inserted into the wedge-shaped groove 319. At this time, the clamp 1 311 and the clamp 2 312 cannot be separated, and the circular clamp composed of the clamp 1 311 and the clamp 2 312 wraps the top of the clamp plate 1 31 and the clamp plate 2 32.

[0045] Specifically, the outside of the clamp 1 311 and the clamp 2 312 is provided with an arc-shaped fixing groove 313 , and the other end of the steel wire rope 4 is sleeved and fixed in the fixing groove 313 outside the clamp 1 311 and the clamp 2 312 .

[0046] By adopting the above technical solution, the user can further fix the combined circular clamp by sleeve one end of the steel wire rope 4 into the fixing groove 313 provided on the outer surfaces of the clamp 1 311 and the clamp 2 312 .

[0047] Specifically, a non-slip rubber pad is fixed to the inner wall of the clamp plate 1 31 , a waterproof sealing pad is fixed to the inner walls of the clamp hoop 1 311 and the clamp hoop 2 312 , and one side of the base 2 is fixedly connected to the clamp plate 2 32 .

[0048] By adopting the above technical solution, the anti-skid rubber pad is used to increase the friction between the fixing mechanism 3 and the electric pole 6 to keep the device stable. At the same time, the built-in waterproof sealing pad can reduce the corrosion damage caused by rainwater penetrating into the fixing mechanism 3 and the surface of the electric pole 6 and the inside of the fixing mechanism 3.

[0049] Working principle: First, the right-angle plate 5 is screwed and fixed to the base 2. The vertical surface with teeth on one side of the right-angle plate 5 is engaged with the teeth in the movable groove 321 and the corresponding position of the surface of the inner lining plate. Then the base 2 and the second card plate 32 fixed on the base 2 are placed at a suitable height on the surface of the electric pole 6. Then the card plate 1 31 is placed on the other side of the electric pole 6. The card plate 1 31 needs to correspond to the card plate 2 32. Then the user takes the card box 35 and aligns the connecting groove 38 on the surface of the card box 35 with the adjacent ends of the card plate 1 31 and the card plate 2 32. The connecting ear plate 34 is inserted into the connecting groove 38 in the card box 35. At this time, the initial fixation of the card plate 1 31 and the card plate 2 32 is completed. Then the user takes the clamp 1 311 and the clamp 2 312, and inserts the plug-in block 315 at the adjacent ends of the clamp 1 311 and the clamp 2 312 into the plug-in groove 317, and then wraps the docking plate 314 on the top of the card plate 1 31 and the card plate 2 32, and gently slides downward, so that the rectangular hole formed by the half groove 1 316 and the half groove 2 318 is passively inserted into the docking block 36 on the top of the card box 35, and the docking block 315 is inserted into the docking block 36 on the top of the card box 35. The connecting column 37 on 6 is inserted into the wedge-shaped groove 319, at which time the clamp 1 311 and the clamp 2 312 cannot be separated, and the circular clamp composed of the clamp 1 311 and the clamp 2 312 wraps the top of the clamp 1 31 and the clamp 2 32 to further fix the clamp 1 31 and the clamp 2 32. Then, the user sleeves one end of the wire rope 4 into the fixing groove 313 on the outer surface of the clamp 1 311 and the clamp 2 312 to further fix the combined circular clamp, and the other end of the wire rope 4 is adjusted and fixed to the base 2 through the wire rope 4 tightening device. Then, the lifting equipment lifts the UHV circuit breaker body 1 to the base 2 for installation. When the base plate bears the gravity of the UHV circuit breaker body 1, it can be tightly fixed by pulling the wire rope 4 downward to the clamp, and the force on the base 2 is shared to the electric pole 6 in the opposite direction. At the same time, the bottom of the base 2 is further slightly deformed by the right-angle plate 5 to the inner lining tooth plate 33, and the inner lining tooth plate 33 is displaced by the guide column 322. The teeth on the inner wall of the inner lining tooth plate 33 are plugged into the surface of the electric pole 6 to further maintain the friction resistance between the device and the electric pole 6, thereby maintaining the stability of the device.
