Description

A small, intelligent pole-mounted circuit breaker for outdoor use Technical Field

[0001] This application relates to the technical field of smart grids, and in particular to a small, intelligent pole-mounted circuit breaker for outdoor use. Background Technology

[0002] Intelligent pole-mounted circuit breakers are core outdoor switching devices in smart grid distribution systems, undertaking critical functions such as line fault detection, isolation, and load control. Their structural design and application directly affect the operational stability and maintenance efficiency of the distribution network. In the current smart grid construction process, outdoor miniature pole-mounted circuit breakers are widely used in the renovation and construction of urban and rural low-voltage distribution lines due to their compact size and ease of operation. These devices typically integrate core components such as the circuit breaker body, control unit, and disconnector, enabling remote or local control of the distribution lines. They are an important foundational hardware for improving the intelligence and automation level of the distribution network.

[0003] The existing outdoor miniature pole-mounted circuit breaker mainly consists of a control box, a circuit breaker body, and three poles, with the poles fixedly mounted on the top surface of the circuit breaker body. To meet installation and maintenance requirements, a fixed support frame is mounted on the bottom of the circuit breaker body, and lifting rings are rotatably connected to the left and right sides for easy lifting and positioning. Several control handles are rotatably mounted on the front of the body for on-site operation by maintenance personnel, while a disconnecting switch is fixed on the rear side to create a clear disconnection point during maintenance. In actual installation, the circuit breaker body and the disconnecting switch are jointly installed on the upper part of the utility pole via crossbars, while the control box is independently fixed to the lower part of the utility pole using clamps. Personnel can monitor and control the operating status of the pole-mounted circuit breaker through the control module inside the control box.

[0004] In the transportation of the aforementioned complete pole-mounted circuit breakers, the circuit breaker body and disconnector switch need to be pre-assembled to avoid precision errors during on-site reassembly. To prevent damage from collisions between the control box and the pre-assembled circuit breaker body and disconnector switch during transportation, existing solutions generally employ separate packaging, where the control box is packaged separately from the other pre-assembled components. While this method reduces the risk of equipment damage, it suffers from significant space utilization issues. It requires more types and quantities of packaging materials, substantially increasing packaging costs, and the redundant packaging volume reduces the load capacity of the transport vehicle, thus increasing the unit transportation cost. Therefore, there is room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide an outdoor miniature intelligent pole-mounted circuit breaker, which solves the problems of low space utilization and high packaging and transportation costs caused by the separate packaging of outdoor miniature complete pole-mounted circuit breakers during transportation in the above-mentioned related technologies.

[0006] This application provides a small, intelligent pole-mounted circuit breaker for outdoor use, employing the following technical solution: A small, intelligent pole-mounted circuit breaker for outdoor use includes a control box, a circuit breaker body, and several poles fixed to the top surface of the circuit breaker body. Support plates are fixed to the left and right edges of the bottom surface of the circuit breaker body, and lifting rings are rotatably connected to the left and right sides. Several control handles are rotatably mounted on the front side of the circuit breaker body, and a disconnecting switch is fixed to the upper part of the back side. A receiving plate is rotatably connected to the lower part of the back side of the circuit breaker body. The receiving plate can be rotated to a horizontal outward receiving state and to a vertical upward storage state. A locking element is provided on the bottom surface of the receiving plate when it is in the receiving state, which limits the position of the receiving plate in the storage state. A positioning element is provided on the bottom surface of the circuit breaker body to limit the position of the receiving plate in the receiving state. A receiving groove is opened on the top surface of the receiving plate when it is in the receiving state for the control box to be placed inside for storage.

[0007] By adopting the above technical solution, during transportation, the receiving plate is rotated to a horizontal receiving state and fixed by positioning components. The control box can be placed into the receiving slot for storage, eliminating the need for separate packaging, significantly improving the utilization rate of transportation space, reducing the amount of packaging materials used, and lowering packaging costs. Simultaneously, it avoids collisions and damage to the control box, circuit breaker body, and disconnector during transportation, ensuring the safety of equipment transportation. During installation and application, the receiving plate can be rotated to a vertical storage state and limited by locking components, without interfering with the normal installation and operation of the equipment. This design balances transportation convenience and installation practicality, effectively solving the problems of low space utilization and high costs associated with existing separate packaging, and improving overall operation and maintenance economy.

[0008] Optionally, the receiving groove is rotatably connected to a cover plate at the inner edge away from the circuit breaker body when the receiving plate is in the receiving state; the cover plate can be rotated to a retracted state inside the receiving groove when the receiving plate is in the storage state, and to a vertically upward limiting state when the receiving plate is in the receiving state; the inner side of the cover plate abuts against the outer side of the control box inside the receiving groove when the receiving plate is in the limiting state.

[0009] By adopting the above technical solution, when the receiving plate is in the receiving state, the cover plate rotates to a vertically upward limiting position, with its inner side abutting against the outer side of the control box inside the receiving groove. This effectively limits the lateral displacement of the control box during transportation, preventing collisions or slippage between the control box and the receiving groove, further improving the stability and safety of the control box during transportation. When storing the receiving plate, the cover plate can be rotated into the receiving groove and stored without occupying extra space or interfering with the storage of the receiving plate or subsequent equipment installation operations. The compact and practical structural design ensures smooth transportation and installation.

[0010] Optionally, the bottom surface of the disconnect switch has two locking slots. The locking element includes two elastic locking rods that are rotatably mounted on the receiving plate and have elastic elongation properties. The rotation surface of the elastic locking rods is parallel to the left and right sides of the circuit breaker body. When the receiving plate is in the retracted state, the elastic locking rods can rotate to a vertically upward locking state, and when the receiving plate is in the receiving state, they can rotate to a vertically downward supporting state. When the elastic locking rod is in the locked state, its upper end can be inserted into the locking slot, and when it is in the supporting state, its lower end surface can be flush with the bottom surface of the supporting plate.

[0011] By adopting the above technical solution, when the receiving plate is stored, the elastic locking rod rotates to a vertically upward locking state, with its upper end inserted into the locking slot of the disconnecting switch. This securely locks the receiving plate in its stored state and enhances the installation stability of the disconnecting switch. When the receiving plate is receiving, the elastic locking rod rotates to a vertically downward supporting state, with its lower end flush with the bottom surface of the support plate. This, together with the support plate, provides stable support for the receiving plate, improving the structural reliability of the receiving plate when carrying the control box. The overall design serves two purposes, simplifying the structure while ensuring stability under different operating conditions and improving the overall adaptability of the equipment.

[0012] Optionally, a first bevel is provided at the opening edge of the locking slot.

[0013] By adopting the above technical solution, the first inclined surface can guide the insertion of the elastic locking rod into the locking slot, reduce the difficulty of alignment, and enable the elastic locking rod to be inserted quickly and smoothly, thereby improving the convenience of the receiving plate storage and locking operation.

[0014] Optionally, a second inclined surface is provided at the outer edge of the end of the elastic locking rod away from the receiving plate.

[0015] By adopting the above technical solution, the second inclined surface can guide the insertion of the elastic locking rod into the locking slot, reduce the difficulty of alignment, and enable the elastic locking rod to be inserted quickly and smoothly, thereby improving the convenience of the receiving plate storage and locking operation.

[0016] Optionally, a support notch is provided on the inner side of the support plate, and a locking protrusion is fixed on the outer periphery of the elastic locking rod, with a locking notch provided on the locking protrusion; the positioning member includes a positioning rod rotatably mounted on the adjacent sides of the two support plates in the horizontal direction, the rotation surface of the positioning rod being parallel to the bottom surface of the circuit breaker body; the positioning rod can rotate to a support state within the support notch when the receiving plate is in the retracted state, and can rotate to a positioning state within the locking notch and be fixed when the receiving plate is in the receiving state and the elastic locking rod is in the support state.

[0017] By adopting this technical solution, the positioning rod can switch to the corresponding notch according to the different states of the receiving plate and the elastic locking rod, achieving a dual limiting function. When the receiving plate is retracted, the positioning rod rotates into the support notch, which can enhance the connection stability between the support plate and the circuit breaker body; when the receiving plate is in the receiving state and the elastic locking rod is supported, the positioning rod rotates into the locking notch and is fixed, which can lock the state of the elastic locking rod, thereby stabilizing the receiving structure of the receiving plate. The overall design does not require additional limiting components, simplifying the structure while improving the operational reliability of the equipment under different working conditions.

[0018] Optionally, a third bevel is provided at the opening edge of the locking notch and the support notch.

[0019] By adopting the above technical solution, the third inclined surface can guide the positioning rod into the locking notch or support notch, reduce the difficulty of alignment, enable the positioning rod to be quickly and accurately engaged, and improve the smoothness of the state switching operation.

[0020] Optionally, the outer periphery of the positioning rod is provided with an elastic snap-fit ​​component, and the inner walls of the locking notch and the support notch are provided with positioning grooves for the elastic snap-fit ​​component to snap into.

[0021] By adopting this technical solution, the elastic snap-fit ​​component can snap into the corresponding positioning groove after the positioning rod is rotated into the locking notch or support notch, thereby realizing the snap-fit ​​fixation between the positioning rod and the notch. This effectively prevents the positioning rod from rotating arbitrarily during equipment transportation or operation, ensuring that the positioning rod's limiting effect on the receiving plate and elastic locking rod is stable and reliable, and improving the overall structural robustness of the equipment.

[0022] Optionally, the elastic snap-fit ​​component includes a compression spring and an arc-shaped protrusion. A placement groove is provided on the outer periphery of the positioning rod for the compression spring and the arc-shaped protrusion to be inserted. The compression spring squeezes one side of the arc-shaped protrusion, causing a part of the arc-shaped protrusion to protrude from the opening of the placement groove. The outer surface of the protruding part of the arc-shaped protrusion is an arc surface, and the arc length corresponding to this arc is a minor arc.

[0023] By adopting this technical solution, the compression spring can continuously squeeze the arc-shaped protrusion to make it partially protrude. Combined with the inferior arc-shaped surface design, it can not only ensure that the elastic snap-fit ​​part can be smoothly snapped into the positioning groove to achieve stable positioning, but also allow the arc-shaped protrusion to smoothly retract into the placement groove under the action of external force when the positioning rod switches states, without the need for additional operation, thus improving the convenience of switching the positioning rod states and the structural adaptability.

[0024] Optionally, a fourth inclined surface is provided at the opening edge of the receiving groove.

[0025] By adopting the above technical solution, the fourth inclined surface can guide the control box into the receiving groove, reduce the difficulty of alignment, and enable the control box to be inserted quickly and smoothly, thereby improving the convenience of equipment storage operations before transportation.

[0026] In summary, this application offers the following beneficial technical advantages: During transportation, the receiving plate is rotated to a horizontal receiving state and fixed by positioning components, allowing the control box to be stored within the receiving slot. This eliminates the need for separate packaging, significantly improving transportation space utilization, reducing packaging material usage, and lowering packaging costs. Simultaneously, it prevents damage to the control box from collisions with the circuit breaker body and disconnector during transportation, ensuring equipment transportation safety. During installation and application, the receiving plate can be rotated to a vertical storage state and limited by locking components, without interfering with normal equipment installation and operation.
