Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and in particular to a solid-insulated pole-mounted circuit breaker. Background Technology

[0002] A solid-insulated pole-mounted circuit breaker is an outdoor high-voltage circuit breaker installed on utility poles. Its core feature lies in its "solid-insulated pole" design. A pole refers to the core component of the circuit breaker that carries current and performs opening and closing operations (including the vacuum interrupter, main conductive circuit, and incoming / outgoing terminals). "Solid-insulated" refers to the process of encapsulating these key conductive components and the vacuum interrupter entirely within a solid insulating material such as high-performance epoxy resin. This design completely isolates the live parts from the external environment, forming a sealed, robust, and reliable insulating whole.

[0003] Currently, a Chinese patent discloses a solid-insulated pole-mounted circuit breaker (authorization announcement number CN220420497U). This utility model utilizes three protective covers at the L-shaped movable rotating plate to shield and protect the contacts, improving the safety of the contacts at the pole contact arm of the circuit breaker. Simultaneously, a return spring allows the rubber telescopic seat to further buffer and protect the contacts, preventing them from being exposed and easily damaged. Two positioning blocks can be used to lock and fix it to the left and right sides of the solid-insulated circuit breaker, while the engagement of four U-shaped limiting plates enhances the stability of the solid-insulated circuit breaker, thus facilitating the installation and removal of the solid-insulated circuit breaker and reducing the labor intensity of workers. However, the above method has the following drawbacks in actual use:

[0004] The operating handwheel, double-acting screw, and threaded plate are exposed. When used on utility poles, they are susceptible to corrosion from rain and snow, and dust will accumulate on their surface. Over time, this can cause them to jam and become impossible to install or remove. Utility Model Content

[0005] Therefore, it is necessary to provide a solid-insulated pole-mounted circuit breaker to address the problem that the operating handwheel, bidirectional screw rotating rod, and threaded plate are exposed and will be corroded by rain and snow when used on utility poles, and that dust will cover their surface and cause them to jam over time.

[0006] A solid-insulated pole-mounted circuit breaker includes: a solid-insulated pole-mounted circuit breaker, wherein the bottom of the solid-insulated pole-mounted circuit breaker is provided with an installation mechanism for installing and fixing the solid-insulated pole-mounted circuit breaker; the installation mechanism includes connecting grooves symmetrically opened at the bottom of the solid-insulated pole-mounted circuit breaker, an installation base provided at the bottom of the solid-insulated pole-mounted circuit breaker, sliding grooves symmetrically opened at the top of the installation base, a corresponding locking block slidably connected in the sliding groove, a through groove opened between the two sliding grooves, a connecting frame slidably connected on both sides and fixedly connected to the locking block, and a bidirectional screw threadedly connected to the connecting frame rotatably connected in the through groove, one end of the bidirectional screw being fixedly connected to a turntable.

[0007] In one embodiment, the solid-sealed pole circuit breaker is symmetrically provided with positioning posts at its bottom, and the mounting base is provided with positioning holes corresponding to the positioning posts at its top.

[0008] In one embodiment, the card block is L-shaped, and the top of the card block has rounded corners.

[0009] In one embodiment, the mounting mechanism further includes a limiting hole arranged in a ring on one side of the mounting base, a fixing rod fixedly connected to one side of the turntable, a pull rod slidably connected inside the fixing rod, and the fixing rod rotating along the ring distribution of the limiting hole.

[0010] In one embodiment, a limiting post with the same diameter as the limiting hole is fixedly connected to one end of the pull rod near the limiting hole, and the limiting post is inserted into the limiting hole.

[0011] In one embodiment, a sealing cap is fixedly connected to one end of the fixing rod, and a through hole with the same diameter as the pull rod is opened on the sealing cap. A spring is provided between the sealing cap and the limiting post.

[0012] In one embodiment, a waterproof sealing ring is provided at the connection between the sealing cover and the fixing rod, and a sealing gasket is provided on the top of the mounting base.

[0013] In one embodiment, the mounting base is made of stainless steel plate, and the mounting base has a through mounting hole.

[0014] Beneficial effects

[0015] 1. An installation mechanism is provided. Rotating the turntable drives the bidirectional lead screw to rotate, thereby rotating the connecting frame and causing the locking blocks to move closer together, locking the solid-sealed pole circuit breaker. A sliding groove is located below the solid-sealed pole circuit breaker, protecting the groove and locking blocks from rainwater corrosion. The bidirectional lead screw is housed within a through groove for further protection, preventing jamming that could prevent the solid-sealed pole circuit breaker from being installed or removed.

[0016] 2. Under the action of the spring, the pull rod drives the limit post to insert into the limit hole, thereby locking the turntable and preventing accidental contact with the turntable from causing the solid-sealed pole circuit breaker to be unlocked and fall off. Attached Figure Description

[0030] The following is combined Figures 1-5 This invention describes a solid-sealed pole-mounted circuit breaker.

[0031] In one embodiment, a solid-pole pole-mounted circuit breaker includes: a solid-pole pole-mounted circuit breaker 100, and an installation mechanism 200 for installing and fixing the solid-pole pole-mounted circuit breaker 100 at its bottom; the installation mechanism 200 includes connecting grooves 211 symmetrically opened at the bottom of the solid-pole pole-mounted circuit breaker 100, an installation base 212 at the bottom of the solid-pole pole-mounted circuit breaker 100, sliding grooves 213 symmetrically opened at the top of the installation base 212, a locking block 214 corresponding to the connecting groove 211 slidably connected in the sliding groove 213, a through groove opened between the two sliding grooves 213, a connecting frame fixedly connected to the locking block 214 on both sides slidably connected in the through groove, and a bidirectional screw threadedly connected to the connecting frame rotatably connected in the through groove, with a turntable 215 fixedly connected to one end of the bidirectional screw thread.

[0032] In this embodiment, the mounting base 212 is installed onto the utility pole using fixing bolts, ensuring the mounting base 212 is horizontal. The solid-state terminal circuit breaker 100 is placed on the mounting base 212, allowing the locking block 214 to enter the connecting groove 211. A rotating turntable 215 drives the bidirectional lead screw to rotate, bringing the two connecting frames closer together and causing the locking block 214 to move towards the connecting groove 211, locking the locking block 214 and the connecting groove 211, thus completing the installation and fixing of the solid-state terminal circuit breaker 100. In rainy or snowy weather, the solid-state terminal circuit breaker 100 is positioned above the mounting base 212, protecting the bidirectional lead screw, connecting frames, and locking block 214 on the mounting base 212 from corrosion and extending their service life.

[0033] like Figure 2 As shown, the bottom of the solid-sealed pole circuit breaker 100 is symmetrically provided with positioning posts 210, and the top of the mounting base 212 is provided with positioning holes 216 corresponding to the positioning posts 210.

[0034] In this embodiment, before locking the solid-state terminal block breaker 100, the positioning post 210 is inserted into the positioning hole 216 to quickly position the solid-state terminal block breaker 100, facilitating its installation and fixation. The positioning post 210 and the positioning hole 216 are tapered to achieve rapid guidance.

[0035] like Figure 3 As shown, the card block 214 is L-shaped, and the top of the card block 214 has rounded corners.

[0036] In this embodiment, the horizontal L-shaped section can hook onto the connecting groove 211 at the bottom of the solid-sealed pole circuit breaker 100, while the vertical section is constrained by the sliding groove 213, forming a bidirectional locking in both horizontal and vertical directions to prevent the solid-sealed pole circuit breaker 100 from coming off under vibration or wind load. Rounded corners eliminate sharp edges to avoid scratching the epoxy resin insulation layer of the circuit breaker housing.

[0037] like Figure 4 As shown, the mounting mechanism 200 also includes a limiting hole 220 arranged in a ring on one side of the mounting base 212, a fixing rod 221 fixedly connected to one side of the turntable 215, a pull rod 222 slidably connected inside the fixing rod 221, and the fixing rod 221 rotates along the ring distribution of the limiting hole 220.

[0038] In this embodiment, after the solid-sealed pole circuit breaker 100 is installed and fixed, one end of the pull rod 222 is inserted into the corresponding limiting hole 220, so that the turntable 215 cannot rotate, thereby avoiding accidental contact with the turntable 215 and causing the solid-sealed pole circuit breaker 100 to loosen, thus improving safety.

[0039] like Figure 4 As shown, a limiting post with the same diameter as the limiting hole 220 is fixedly connected to one end of the pull rod 222 near the limiting hole 220, and the limiting post is inserted into the limiting hole 220.

[0040] In this embodiment, the limiting post is inserted into the limiting hole 220 to prevent the pull rod 222 from moving out of the limiting hole 220 under the influence of vibration or other factors, which would cause the turntable 215 to fail to lock.

[0041] like Figure 4 As shown, a sealing cover 223 is fixedly connected to one end of the fixing rod 221. The sealing cover 223 has a through hole with the same diameter as the pull rod 222. A spring is provided between the sealing cover 223 and the limiting post.

[0042] In this embodiment, the spring compresses the limiting post, causing it to tend to move into the limiting hole 220, further improving the locking effect on the turntable 215 and enhancing safety. When it is necessary to disassemble the solid-sealed pole circuit breaker 100, pull the pull rod 222 outward to move the limiting post out of the limiting hole 220, then rotate the turntable 215 to unlock the solid-sealed pole circuit breaker 100.

[0043] like Figure 1 and Figure 5 As shown, a waterproof sealing ring is provided at the connection between the sealing cover 223 and the fixing rod 221, and a sealing gasket is provided on the top of the mounting base 212.

[0044] In this embodiment, a waterproof sealing ring and a sealing gasket are provided to improve the sealing performance and prevent rainwater from entering the fixing rod 221 and the slide groove 213 through gaps and corroding the parts.

[0045] like Figure 1 As shown, the mounting base 212 is made of stainless steel plate, and the mounting base 212 has mounting holes that penetrate through the mounting base 212.

[0046] In this embodiment, mounting holes are provided to facilitate fixing the mounting base 212 to the utility pole. The mounting base 212 is made of stainless steel plate to improve corrosion resistance and adapt to the outdoor environment.

[0047] Working principle: The mounting base 212 is fixed to the crossarm of the utility pole with U-bolts. After adjusting the level of the base, the solid-state pole circuit breaker 100 is hoisted. After the bottom positioning pin 210 is accurately inserted into the positioning hole 216 and locked, the turntable 215 is rotated clockwise to drive the bidirectional lead screw to rotate, which drives the connecting frame to slide towards the center. This, in turn, pushes the L-shaped locking blocks 214 on both sides to move horizontally along the slide groove 213, so that the horizontal section is embedded in the bottom connecting groove 211 of the solid-state pole circuit breaker 100, forming a mechanical interlock. The limit pin is aligned with the annularly distributed limit holes 220 and released, so that the spring pushes the limit pin into the hole, locking the turntable 215 to prevent accidental contact and rotation, and ensure safety.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
