Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and more specifically to a capacitor-powered primary-secondary integrated pole-mounted circuit breaker. Background Art

[0002] The capacitor-powered integrated primary and secondary pole-mounted circuit breaker uses capacitor power to supply power to the secondary equipment. The secondary equipment collects and analyzes data to control the on and off of the primary equipment, thereby realizing the protection and control of the power line and ensuring the safe and stable operation of the power system. Among them, the primary equipment is mainly the circuit breaker body. During normal operation, the circuit breaker is in a closed state and the current can pass smoothly. When overload, short circuit and other faults occur in the circuit, the control unit in the secondary equipment will send a trip signal to allow the circuit breaker to quickly trip and cut off the circuit. There is an alternating electric field in the high-voltage line. The capacitor elements in the capacitor power-taking device will accumulate and move charges under the action of this alternating electric field, thereby forming a current, achieving the purpose of obtaining electrical energy from the high-voltage line, and providing working power for the secondary equipment of the pole-mounted circuit breaker, such as the control unit, protection unit, etc., to ensure that these devices can operate normally.

[0003] Existing circuit breakers usually place capacitor elements in the mechanism box. The mechanism box is an important component of the circuit breaker and is used to accommodate components such as the operating mechanism. Placing the capacitor power supply module here facilitates electrical connection with other control and operating components of the circuit breaker to provide a stable power supply. However, the heat dissipation and heat preservation effects of the mechanism box are poor. When the circuit breaker is used in hot summer weather, the high temperature will accelerate the chemical reaction rate inside the capacitor, causing the aging of the insulating medium of the capacitor to accelerate, causing the performance of the capacitor to gradually decline and shorten its life. In addition, when it is in a high temperature environment for a long time, the structure inside the capacitor may become loose or cracked, affecting the performance and life of the capacitor. When used in a low temperature environment in winter, the low temperature will change the dielectric properties inside the capacitor, resulting in a decrease in its ability to store charge. The capacity of the capacitor will usually decrease, causing the capacitor to bear a greater burden when working, indirectly affecting its life. In view of this, we propose a capacitor power supply type primary and secondary integrated pole-mounted circuit breaker. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention designs a module housing, a linkage adjustment component, an inner frame component and an outer frame component. The linkage adjustment component can be used to adjust the first inner frame and the second inner frame to form a separated state or a combined state, and at the same time drive the first outer frame and the second outer frame to form a separated state or a combined state. In the separated state, multiple heat dissipation fins are exposed, which increases the heat dissipation area and can effectively take away the heat generated by the capacitor element inside the module housing. The upper ventilation duct formed by the inner cavity of the first inner frame and the first outer frame is connected, and the lower ventilation duct formed by the inner cavity of the second inner frame and the second outer frame is connected, so that the natural wind from the outside can blow into the multiple heat dissipation fins through the upper ventilation duct and blow out through the lower ventilation duct to take away the heat, or blow in through the lower ventilation duct and blow out through the upper ventilation duct. Natural wind is effectively used to dissipate heat from the module shell. In a combined state, multiple heat dissipation fins are enclosed by the first inner frame and the second inner frame to form a closed state, so that a relatively closed thermal insulation air layer is formed between the multiple heat dissipation fins. At the same time, the first outer frame and the second outer frame respectively form a sealing effect on the upper ventilation duct and the lower ventilation duct, making it difficult for natural wind to enter the interior, thereby isolating the external environment and effectively insulating the module shell. Through the mutual cooperation of the inner frame assembly and the outer frame assembly, the device has a better heat dissipation effect when used in a high temperature environment in summer, and a better thermal insulation effect when used in a low temperature environment in winter, which can greatly avoid the adverse effects of high temperature environment or low temperature environment on capacitor elements, thereby improving the performance and life of the capacitor elements.

[0017] 2. The present invention designs the upper ventilation chamber to have a structure that contracts and narrows from the input end to the output end, and designs the lower ventilation chamber to have a structure that contracts and narrows from the input end to the output end, so that when natural wind blows into the interior from the upper ventilation chamber, or blows into the interior from the lower ventilation chamber, the volume of the wind is gradually compressed. While the wind volume remains unchanged, the flow rate of the natural wind can be increased, the wind force of the natural wind can be increased, and the impact force of the natural wind on the multiple cooling fins can be further increased. While taking away the heat, the dust particles on the surface of the cooling fins can be blown away, avoiding the accumulation of dust particles on the surface of the cooling fins, which easily prevents the heat from being dissipated, thereby further improving the heat dissipation effect and ensuring the cleanliness of the cooling fins.

[0018] 3. In the present invention, when natural wind blows from the upper ventilation chamber to the connection port 1, the natural wind blows the upper part of the fan blade through the upper ventilation chamber, driving the fan blade to rotate, and the fan blade drives another fan blade to rotate synchronously in the same direction through the screw rod, so that the other fan blade can guide the incoming natural wind from the heat dissipation fin area to the lower ventilation chamber. When the natural wind blows from the lower ventilation chamber to the connection port 2, the natural wind blows the lower part of the fan blade through the lower ventilation chamber, driving the fan blade to rotate, and similarly drives another fan blade to rotate, and the other fan blade guides the incoming natural wind from the heat dissipation fin area to the upper ventilation chamber, so that no matter which direction the wind blows in, an effective blowing path can be formed, thereby ensuring the smooth circulation of natural wind, allowing the natural wind to continuously take away internal heat, and further improving the heat dissipation efficiency.

[0019] 4. The present invention allows natural wind to enter from the upper ventilation duct, driving the fan blades to rotate, the fan blades drive the screw to rotate, the screw drives the movable frame to slide forward along the guide rod, and further drives multiple dust scrapers to scrape the outer surfaces of multiple cooling fins respectively, scraping away the dust on the outer surfaces of the cooling fins, keeping the outer surfaces of the cooling fins clean, thereby improving the heat dissipation effect of the cooling fins; when the wind direction changes and natural wind enters from the lower ventilation duct, the fan blades are driven to rotate in the opposite direction, thereby causing the screw to drive the movable frame to slide in the opposite direction along the guide rod, so that the dust scraper can use the wind force of the natural wind to scrape back and forth on the cooling fins, further improving the cleaning effect of the cooling fins.

[0020] 5. The present invention arranges the scraping head of the lower scraper to be a wedge-shaped structure inclined from the inside to the outside toward the frame plate. When the lower scraper scrapes the top of the heat sink fin, the dust on the top of the heat sink fin can gradually move toward the side of the heat sink fin along the inclined angle generated by the wedge-shaped structure of the scraping head of the lower scraper until it moves out of the top of the heat sink fin, thereby avoiding the dust from easily accumulating on the scraping head of the lower scraper and causing poor cleaning effect, and further improving the cleaning ability of the lower scraper on the heat sink fin.

[0045] In an embodiment of the present invention, the inner frame assembly 4 is arranged on the side of the module shell 2, and the outer frame assembly 5 is arranged on the side of the inner frame assembly 4. The top of the module shell 2 is movably connected to the inner frame assembly 4 and the outer frame assembly 5 through the linkage adjustment assembly 3; the side wall of the module shell 2 is detachably connected with an inspection plate 201, and the inspection plate 201 is fixed to the side wall of the module shell 2 by screws, which is convenient for disassembly of the inspection plate 201 and for inspection of the capacitor elements inside the module shell 2. The side wall of the inspection plate 201 is connected with a plurality of heat dissipation fins 202, and the heat dissipation fins 202 are a sheet-like rectangular structure. The plurality of heat dissipation fins 202 are arranged in the inner cavity of the inner frame assembly 4.

[0046] Among them, the inner frame assembly 4 is composed of a first inner frame 41 and a second inner frame 42, and the outer frame assembly 5 is composed of a first outer frame 51 and a second outer frame 52; the linkage adjustment assembly 3 is used to adjust the first inner frame 41 and the second inner frame 42 to form a separated state or a merged state, and at the same time drive the first outer frame 51 and the second outer frame 52 to form a separated state or a merged state; in the separated state, the inner cavities of the first inner frame 41 and the first outer frame 51 are connected to form an upper ventilation duct, and the inner cavities of the second inner frame 42 and the second outer frame 52 are connected to form a lower ventilation duct; in the merged state, the first inner frame 41 and the second inner frame 42 form an enclosure for multiple heat dissipation fins 202, the first outer frame 51 forms a closure for the upper ventilation duct, and the second outer frame 52 forms a closure for the lower ventilation duct.

[0047] The present invention designs a module shell 2, a linkage adjustment component 3, an inner frame component 4 and an outer frame component 5. The linkage adjustment component 3 can be used to adjust the first inner frame 41 and the second inner frame 42 to form a separated state or a merged state, and at the same time drive the first outer frame 51 and the second outer frame 52 to form a separated state or a merged state. In the separated state, multiple heat dissipation fins 202 are exposed, which increases the heat dissipation area and can effectively take away the heat generated by the capacitor element inside the module shell 2. The upper ventilation duct formed by the inner cavities of the first inner frame 41 and the first outer frame 51 are connected, and the lower ventilation duct formed by the inner cavities of the second inner frame 42 and the second outer frame 52 are connected, so that the natural wind from the outside can blow into the multiple heat dissipation fins 202 through the upper ventilation duct and blow out through the lower ventilation duct to take away the heat, or blow in through the lower ventilation duct and blow out through the upper ventilation duct, thereby effectively utilizing the natural wind to dissipate the heat of the module shell 2.

[0048] In the combined state, the plurality of heat dissipation fins 202 are enclosed by the first inner frame 41 and the second inner frame 42 to form a closed state, so that a relatively closed heat-insulating air layer is formed between the plurality of heat dissipation fins 202. At the same time, the first outer frame 51 and the second outer frame 52 respectively form a closing effect on the upper ventilation duct and the lower ventilation duct, making it difficult for natural wind to enter the interior, thereby isolating the external environment and effectively insulating the module housing 2. Through the mutual cooperation of the inner frame assembly 4 and the outer frame assembly 5, the device has a better heat dissipation effect when used in a high-temperature environment in summer and a better heat preservation effect when used in a low-temperature environment in winter, and can avoid the adverse effects of high-temperature environment or low-temperature environment on the capacitor element to a great extent.

[0049] As another embodiment of the present invention, the first inner frame 41 and the second inner frame 42 are arranged in a symmetrical structure, the first outer frame 51 is arranged on the side of the first inner frame 41, and the second outer frame 52 is arranged on the side of the second inner frame 42; wherein, the first inner frame 41 and the second inner frame 42 are both concave plate-like structures, the side wall of the first inner frame 41 is provided with a connection port 1 4101, the side wall of the second inner frame 42 is provided with a connection port 2 4201, the first outer frame 51 is provided with an upper ventilation chamber 5101, and the second outer frame 52 is provided with a lower ventilation chamber 5201; the upper ventilation chamber 5101 is an arc-shaped chamber structure, and a protective net 5102 is arranged at the input end of the upper ventilation chamber 5101, and the protective net 5102 can prevent external The dead branches and leaves in the external environment enter the upper ventilation chamber 5101, and the output end of the upper ventilation chamber 5101 is arranged at the upper end of the side wall of the first outer frame 51, and the chamber of the upper ventilation chamber 5101 is contracted and narrowed from the input end to the output end, and an upper ventilation duct is formed when the upper ventilation chamber 5101 is connected with the connecting port 1 4101; the lower ventilation chamber 5201 is an arc-shaped chamber structure, and the input end of the lower ventilation chamber 5201 is arranged with the same structure as the protective net 5102, and the output end of the lower ventilation chamber 5201 is arranged at the lower end of the side wall of the second outer frame 52, and the chamber of the lower ventilation chamber 5201 is contracted and narrowed from the input end to the output end, and a lower ventilation duct is formed when the lower ventilation chamber 5201 is connected with the connecting port 2 4201.

[0050] The present invention designs the upper ventilation chamber 5101 as a structure that shrinks and narrows from the input end to the output end, and designs the lower ventilation chamber 5201 as a structure that shrinks and narrows from the input end to the output end, so that when natural wind blows into the interior from the upper ventilation chamber 5101, or blows into the interior from the lower ventilation chamber 5201, the volume of the wind is gradually compressed. When the wind volume remains unchanged, the flow rate of the natural wind can be increased, the wind force of the natural wind can be increased, and the impact force of the natural wind on the multiple heat dissipation fins 202 can be further increased. While taking away the heat, the dust particles on the surface of the heat dissipation fins 202 can be blown away, avoiding the accumulation of dust particles on the surface of the heat dissipation fins 202, thereby preventing the heat from being easily prevented from dissipating, thereby further improving the heat dissipation effect and ensuring the cleanliness of the heat dissipation fins 202.
