Description

Technical Field

[0001] This invention relates to the field of circuit breaker technology, and in particular to a pole-mounted circuit breaker with deep integration of primary and secondary protection. Background Technology

[0002] With the accelerated pace of power grid intelligence, pole-mounted circuit breakers, which deeply integrate primary and secondary circuits, have become core equipment for distribution network automation upgrades due to their high integration and convenient operation and maintenance. However, when traditional circuit breakers operate in humid environments for extended periods, internal condensation remains a critical hidden danger affecting equipment reliability. Condensation droplets adhering to insulation surfaces or metal connections can easily cause partial discharge, insulation degradation, and even short-circuit faults, leading to frequent maintenance and unexpected power outages, severely restricting power supply stability.

[0003] While existing technologies mitigate moisture intrusion through methods such as sealed enclosures and built-in dehumidifiers, they suffer from two major drawbacks: First, static sealing structures are prone to internal condensation under temperature variations, especially outdoor pole-mounted equipment where large day-night temperature differences cause moisture to condense at the top of the enclosure and drip onto critical components, accelerating corrosion and insulation failure. Second, traditional dehumidifiers rely heavily on passive moisture-absorbing materials, requiring regular replacement and maintenance, and cannot continuously block external moisture penetration, resulting in unstable dehumidification effects and difficulty adapting to the high humidity or rainy climates of southern regions. Summary of the Invention

[0004] This invention discloses a primary and secondary deep integration protection pole-mounted circuit breaker, which aims to solve the technical problems of unstable dehumidification effect, water vapor condensing on the top of the housing and dripping onto key components, accelerating corrosion and insulation failure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A primary and secondary deep-integration protective pole-mounted circuit breaker includes a primary and secondary deep-integration pole-mounted circuit breaker body, and further includes: a circuit breaker base, fixed to the bottom end of the primary and secondary deep-integration pole-mounted circuit breaker body; a sealing chamber, wrapped around the outer periphery of the circuit breaker base, and sealed at the connection with the primary and secondary deep-integration pole-mounted circuit breaker body; a base frame, fixedly installed on the inner wall of the bottom end of the sealing chamber, and the circuit breaker base fixedly installed on the top end of the base frame; a dehumidification mechanism connected to the sealing chamber; and an air intake regulating mechanism connected to the dehumidification mechanism; the dehumidification mechanism includes: an air outlet, penetrating... A filter screen is installed on the top inner wall of the sealed chamber and movablely covered outside the air outlet; multiple air inlets are installed on the bottom inner wall of the sealed chamber; multiple air inlet pipes are fixedly connected to the bottom inner wall of the air inlets; an inner limiting ring is fixedly connected to the circumferential inner wall of the air inlet pipe; a mounting bracket has its outer circumferential wall movably attached to the circumferential inner wall of the air inlet pipe, and a hydrophobic membrane is fixedly attached to the inner wall of the mounting bracket, which is movably attached to the bottom end of the inner limiting ring; and an air guide fan has a motor fixedly connected to its center position, and the air guide fan is connected to the tail end of the air inlet pipe through a connecting mechanism. The dehumidification mechanism further includes: a water-blocking enclosure, which is fixedly connected to the top outer wall of the sealed chamber and surrounds the outer periphery of the air outlet; a support frame, which is tightly pressed against the inner wall of the water-blocking enclosure, and the filter screen is fixedly installed on the inner wall of the support frame; and an L-shaped water baffle, which is fixedly connected to one side outer wall of the sealed chamber and blocks the top of the air outlet.

[0006] By incorporating a dehumidification mechanism and establishing an independent cavity around the circuit breaker base through a sealed chamber, external moisture is isolated. Air enters through the bottom inlet and exits through the top outlet. During the intake process, moisture in the air is isolated outside the hydrophobic membrane after passing through it, allowing dry air to enter the sealed chamber. This ensures a relatively dry environment within the sealed chamber. This structure not only provides auxiliary heat dissipation but also prevents moisture from directly intruding into the connections of critical components, effectively reducing the maintenance frequency of the primary and secondary integrated pole-mounted circuit breaker body.

[0007] In a preferred embodiment, slots are provided through both sides of the sealed chamber, and each slot is covered with an inspection plate. The inspection plate is fixed to the inner wall of the sealed chamber by bolts, and a humidity measuring instrument is fixedly installed on one side of the sealed chamber. The intake adjustment mechanism includes: an annular extension frame, fixedly connected to the inner wall of the bottom end of the intake pipe; and two linear electric guide rails, symmetrically fixedly connected to the outer circumference of the annular extension frame. The intake adjustment mechanism further includes: two sliders, which are movably connected to two linear electric guide rails respectively; and two L-shaped brackets, which are fixedly connected to the bottom outer wall of the two sliders respectively, and the two L-shaped brackets are symmetrically arranged. The intake adjustment mechanism further includes: two arc-shaped extrusion plates, which are respectively fixedly connected to the ends of two L-shaped brackets, and the two arc-shaped extrusion plates are symmetrically arranged; an elastic pipe, which is fixedly connected to the inner wall of the bottom end of the intake pipe, and the two arc-shaped extrusion plates are respectively fixedly attached to the outer circumference of the elastic pipe.

[0008] The ambient humidity can be monitored in real time by the humidity meter. When the humidity is too high in rainy weather, a signal is sent to control the linear electric guide rail to move the slider and reduce the air intake space. By reducing the amount of air entering at one time, the real-time filtration load of the hydrophobic membrane can be reduced, thereby solving the problem of increased membrane air permeability resistance in rainy weather. Thus, while reducing the membrane load, a relatively dry environment can also be ensured in the sealed chamber.

[0009] In a preferred embodiment, the connecting mechanism includes: a sleeve, which is fixedly installed on one side of the outer wall of the air intake pipe, and a damping ring is fixedly embedded in the inner wall of the sleeve; a fan outer frame, on which the air guide fan and the motor are simultaneously installed; and a limiting rod, which is fixedly connected to the top outer wall of the fan outer frame, and the limiting rod is movably inserted into the damping ring. The connecting mechanism further includes: a support rod, fixedly connected to the center of the air guide fan; a silicone scraper, fixedly connected to one side of the outer wall of the support rod, and the silicone scraper is movably attached to the bottom end of the hydrophobic membrane; and a handle, fixedly connected to the bottom outer wall of the fan outer frame. The connecting mechanism further includes: a compression ring, which is fixedly connected to the top outer wall of the fan outer frame and movably compressed against the bottom outer wall of the mounting bracket; a snap-fit ​​bracket, which is fixedly connected to one side outer wall of the fan outer frame; and an outer sleeve, which is fixedly connected to the bottom outer wall of the sealing chamber. The connecting mechanism further includes: an inner sleeve, which is movably fitted to the inner circumferential wall of the outer sleeve; a spring, whose two ends are respectively fixedly connected to the inner walls of the outer sleeve and the inner sleeve; a hinge seat, which is fixedly connected to the bottom outer wall of the inner sleeve; and a hook, which is movably hinged to the hinge seat and simultaneously engaged with the engagement bracket.

[0010] The system incorporates a connecting mechanism, which, through the support rod and silicone scraper, synchronously drives the silicone scraper to rotate, cleaning up adhering dust to ensure breathability during long-term use. Furthermore, the connection structure based on the limiting rod and hook facilitates the disassembly and replacement of the hydrophobic membrane. Correspondingly, the longitudinal limiting of the limiting rod and the upward pull of the spring ensure stable installation of the fan's outer frame. This structure is simple to operate and reduces the difficulty of replacing and maintaining the hydrophobic membrane.

[0011] As described above, a primary and secondary deep-integration protective pole-mounted circuit breaker includes a primary and secondary deep-integration pole-mounted circuit breaker body, a circuit breaker base fixed to the bottom end of the primary and secondary deep-integration pole-mounted circuit breaker body; a sealing chamber wrapped around the outer periphery of the circuit breaker base, and the connection between the sealing chamber and the primary and secondary deep-integration pole-mounted circuit breaker body is sealed; a base frame fixedly installed on the inner wall of the bottom end of the sealing chamber, and the circuit breaker base fixedly installed on the top end of the base frame; a dehumidification mechanism connected to the sealing chamber; and an air intake regulating mechanism connected to the dehumidification mechanism; the dehumidification mechanism includes: an air outlet, The device comprises: a top inner wall penetrating the sealed chamber, with a filter screen movably covering the air outlet; multiple air inlets penetrating the bottom inner wall of the sealed chamber; multiple air inlet pipes fixedly connected to the bottom inner wall of each air inlet; an inner limiting ring fixedly connected to the circumferential inner wall of each air inlet pipe; a mounting bracket whose outer circumferential wall movably fits against the circumferential inner wall of each air inlet pipe, with a hydrophobic membrane fixedly fitted to the inner wall of the mounting bracket, and the mounting bracket movably fitting against the bottom of the inner limiting ring; and an air guide fan with a motor fixedly connected to its center, connected to the tail end of each air inlet pipe via a connecting mechanism. This invention provides a primary and secondary deep-integration protective pole-mounted circuit breaker that achieves auxiliary heat dissipation while preventing moisture from directly intruding into the connection points of critical components.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The pole-mounted circuit breaker with primary and secondary deep integration protection disclosed in this invention is mainly applied to scenarios where circuit breakers are used.

[0020] Reference Figures 1-4A primary and secondary deep integration protection pole-mounted circuit breaker includes a primary and secondary deep integration pole-mounted circuit breaker body 1, a circuit breaker base fixed to the bottom of the primary and secondary deep integration pole-mounted circuit breaker body 1, a sealing chamber 3 wrapped around the outer periphery of the circuit breaker base and sealed at the connection with the primary and secondary deep integration pole-mounted circuit breaker body 1, a dehumidification mechanism 2 connected to the sealing chamber 3, an air intake adjustment mechanism 6 connected to the dehumidification mechanism 2, and a base frame 8 fixedly installed at the bottom of the sealing chamber 3. The circuit breaker base is fixedly installed on the top of the base frame 8.

[0021] The sealing chamber 3 has an air outlet 205 extending through its top and multiple air inlets 206 extending through its bottom. The dehumidification mechanism 2 includes a filter 203, multiple air inlets 207, an inner limiting ring 208, a mounting bracket 209, and a guide fan 211. The filter 203 is installed over the air outlet 205. The multiple air inlets 207 are fixedly connected to the multiple air inlets 206, and the inner limiting ring 208 is fixedly connected to the inner circumferential wall of the air inlets 207. The outer circumferential wall of the mounting bracket 209 is movably attached to the inner circumferential wall of the air inlets 207, and a hydrophobic membrane 210 is fixedly attached to the inner wall of the mounting bracket 209. The mounting bracket 209 is movably attached to the bottom of the inner limiting ring 208. The guide fan 211 has a motor 212 fixedly connected to its center position, and the guide fan 211 is connected to the tail end of the air inlets 207 through a connecting mechanism 7.

[0022] An independent cavity is created by sealing chamber 3 around the circuit breaker base, isolating it from external moisture. Air is then introduced through the bottom air inlet 206, supported by the base frame 8, creating a hollow structure at the bottom connection point. Exhaust is then vented through the top air outlet 205. During the air intake process, the airflow is driven by the air guide fan 211. After passing through the hydrophobic membrane 210, the moisture in the air is isolated outside the hydrophobic membrane 210, and dry air enters the sealing chamber 3. With the continuous entry of dry air, the moisture in the sealing chamber 3 is squeezed out through the air outlet 205, thus ensuring a relatively dry state inside the sealing chamber 3. With this structure, auxiliary heat dissipation can be achieved while preventing moisture from directly invading the connection points of critical components, effectively reducing the maintenance frequency of the primary and secondary deep-integration pole-mounted circuit breaker body 1.

[0023] Reference Figure 2In a preferred embodiment, the dehumidification mechanism 2 further includes a water-blocking enclosure 201, a support frame 202, and an L-shaped water-blocking plate 204. The water-blocking enclosure 201 is fixedly connected to the top outer wall of the sealed chamber 3 and surrounds the outer periphery of the air outlet 205. The support frame 202 is tightly pressed against the inner wall of the water-blocking enclosure 201, and the filter screen 203 is fixedly installed on the inner wall of the support frame 202. The L-shaped water-blocking plate 204 is fixedly connected to one side outer wall of the sealed chamber 3 and blocks the top of the air outlet 205. The L-shaped water-blocking plate 204 can prevent rainwater from entering the sealed chamber 3 through the air outlet 205 in rainy weather, while the water-blocking enclosure 201 can prevent rainwater from accumulating at the top of the sealed chamber 3 and entering the sealed chamber 3 as the water level rises, thus ensuring a dry environment inside the sealed chamber 3.

[0024] Reference Figure 4 In a preferred embodiment, the connecting mechanism 7 includes a sleeve 702, a limiting rod 705, and a fan outer frame 708. The sleeve 702 is fixedly installed on one side of the outer wall of the air intake pipe 207, and a damping ring 701 is fixedly embedded in the inner wall of the sleeve 702. The limiting rod 705 is fixedly connected to the top outer wall of the fan outer frame 708, and the limiting rod 705 is movably inserted into the damping ring 701. The fan outer frame 708, the air guide fan 211, and the motor 212 are all installed on the fan outer frame 708.

[0025] Reference Figure 4 , Figure 5 In a preferred embodiment, the connecting mechanism 7 further includes a silicone scraper 703, a support rod 704, a handle 706, a compression ring 707, a snap-fit ​​bracket 709, and an outer sleeve 710; the support rod 704 is fixedly connected to the center of the air guide fan 211; the silicone scraper 703 is fixedly connected to one side of the outer wall of the support rod 704, and the silicone scraper 703 is movably attached to the bottom end of the hydrophobic membrane 210; the handle 706 is fixedly connected to the bottom outer wall of the fan outer frame 708; the compression ring 707 is fixedly connected to the top outer wall of the fan outer frame 708, and is movably compressed against the bottom outer wall of the mounting bracket 209; the snap-fit ​​bracket 709 is fixedly connected to one side of the outer wall of the fan outer frame 708; and the outer sleeve 710 is fixedly connected to the bottom outer wall of the sealing chamber 3.

[0026] Reference Figure 4 , Figure 5 In a preferred embodiment, the connecting mechanism 7 further includes an inner sleeve 712, a spring 711, a hinge seat 713, and a hook 714; the inner sleeve 712 is movably fitted against the inner circumferential wall of the outer sleeve 710; the two ends of the spring 711 are respectively fixedly connected to the inner walls of the outer sleeve 710 and the inner sleeve 712; the hinge seat 713 is fixedly connected to the bottom outer wall of the inner sleeve 712; the hook 714 is movably hinged to the hinge seat 713 and simultaneously engaged with the engagement bracket 709.

[0027] The design incorporates a support rod 704 and a silicone scraper 703. Simultaneously, the motor 212 drives the air-guiding fan 211 to rotate, while the silicone scraper 703 rotates, acting on the bottom of the hydrophobic membrane 210 to clean adhering dust and ensure breathability during long-term use. Furthermore, based on the connection structure of the limiting rod 705 and the hook 714, the hand grip 706 can rotate and raise / lower the fan outer frame 708, allowing the compression ring 707 to disengage from the air intake pipe 207. It can also rotate around the limiting rod 705 as an axis. The hydrophobic membrane 210 can then be disassembled and replaced. Correspondingly, if the hydrophobic membrane 210 needs to be installed, the mounting bracket 209 is inserted directly, and then the fan outer frame 708 is restored. The mounting bracket 209 is clamped and limited by the inner limiting ring 208 and the compression ring 707, and then the hook 714 is pulled down to make it snap into the snap-fit ​​bracket 709. The fan outer frame 708 can be stably installed by the longitudinal limiting rod 705 and the upward pulling of the spring 711. This structure is simple to operate and can reduce the difficulty of replacing and repairing the hydrophobic membrane 210.

[0028] Reference Figure 1 In a preferred embodiment, slots are provided through both sides of the sealed chamber 3, and each slot is covered with a maintenance plate 4. The maintenance plate 4 is fixed to the inner wall of the sealed chamber 3 by bolts. The maintenance plate 4 can be opened from this position to facilitate the maintenance of the components inside the sealed chamber 3. A humidity measuring instrument 5 is fixedly installed on one side of the sealed chamber 3.

[0029] Reference Figure 3 In a preferred embodiment, the intake adjustment mechanism 6 includes an annular extension frame 606, two linear electric guide rails 601, two sliders 602, and two L-shaped brackets 603. The annular extension frame 606 is fixedly connected to the inner wall of the bottom end of the intake pipe 207, and the two linear electric guide rails 601 are symmetrically fixedly connected to the outer circumferential wall of the annular extension frame 606. The two sliders 602 are movably connected to the two linear electric guide rails 601 respectively. The two L-shaped brackets 603 are fixedly connected to the outer wall of the bottom end of the two sliders 602 respectively, and the two L-shaped brackets 603 are symmetrically arranged.

[0030] Reference Figure 3 In a preferred embodiment, the intake regulating mechanism 6 further includes two arc-shaped extrusion plates 604 and an elastic pipe 605; the two arc-shaped extrusion plates 604 are respectively fixedly connected to the ends of the two L-shaped brackets 603, and the two arc-shaped extrusion plates 604 are symmetrically arranged; the elastic pipe 605 is fixedly connected to the bottom inner wall of the intake pipe 207, and the two arc-shaped extrusion plates 604 are respectively fixedly attached to the outer circumferential wall of the elastic pipe 605.

[0031] The humidity meter 5 can monitor the ambient humidity in real time. When the humidity is too high in rainy weather, a signal is sent to control the linear electric guide rail 601 to move the slider 602, which in turn drives the two arc-shaped extrusion plates 604 to squeeze the elastic pipe 605, reducing the air intake space. At the same speed of the air guide fan 211, the smaller the air intake, the smaller the air volume. By reducing the amount of air entering at one time, the real-time filtration load of the hydrophobic membrane 210 can be reduced, thereby solving the problem of increased membrane air permeability resistance in rainy weather. At the same time, since the humidity in the rainy weather environment is close to saturation, the moisture in the sealed chamber 3 evaporates slowly, and there is no need for a large amount of dry air replacement. Also, based on the slightly positive pressure environment in the sealed chamber 3, the high humidity air outside cannot flow back from the air outlet 205. Thus, while reducing the membrane load, a relatively dry environment in the sealed chamber 3 can also be ensured.

[0032] Working principle: The sealed chamber 3 is enclosed by a ring around the circuit breaker base to create an independent cavity, isolating it from external moisture. Air is introduced through the bottom air inlet 206, supported by the base frame, creating a hollow structure at the bottom connection position, and then vented through the top air outlet 205. During the air intake process, the airflow is driven by the air guide fan 211. After passing through the hydrophobic membrane 210, the moisture in the air is isolated outside the hydrophobic membrane 210, and dry air enters the sealed chamber 3. With the continuous entry of dry air, the moisture in the sealed chamber 3 is squeezed out through the air outlet 205, thus ensuring a relatively dry state inside the sealed chamber 3. With this structure, while achieving auxiliary heat dissipation, it can also prevent moisture from directly invading the connection points of key components, effectively reducing the maintenance frequency of the primary and secondary deep fusion pole-mounted circuit breaker body 1.
