[0002] With the national goal of "carbon peaking and carbon neutrality," the transformation of the power grid towards smart grids and digital grids is accelerating, and the integration of distributed and renewable energy sources is constantly increasing. This places higher demands on the stability and reliability of the distribution network. In traditional power systems, there are problems such as interface mismatch and equipment incompatibility between primary and secondary equipment, resulting in low operation and maintenance efficiency and long fault handling time. Therefore, the technology of primary and secondary integration has emerged to improve the construction level, operation level, and operation and maintenance quality and efficiency of the distribution network.

[0003] By tightly integrating primary and secondary equipment into a complete system, the size and weight of the equipment are reduced, making it easier to install and transport. It has adaptive integrated local feeder automation functions, which can automatically detect, locate and isolate faults, thereby improving power supply reliability.

[0004] However, the current integrated primary and secondary pole-mounted circuit breaker structure is not compact and reasonable, lacks effective heat dissipation and protection mechanisms, cannot effectively prevent dust and rain, and cannot effectively protect the equipment body. In view of this, we propose an integrated primary and secondary pole-mounted circuit breaker and its structure. Summary of the Invention

[0011] Preferably, the single set of protective cylinders has multiple sets of arc grooves and round holes, and the interiors of the multiple sets of arc grooves and round holes are interconnected, thereby improving the heat dissipation effect.

[0012] Preferably, multiple sets of movable electrode plates and insulating blocks are provided, and the multiple sets of movable electrode plates and insulating blocks are arranged vertically in an alternating manner to prevent short circuits. The cross-sectional area of ​​the movable electrode plate is smaller than that of the insulating block.

[0020] A closing handle is provided on the switch body;

[0021] A switch pointer is provided on the switch body.

[0022] Compared with the prior art, the present invention provides a primary and secondary integrated pole-mounted switch circuit breaker and its structure, which has the following beneficial effects:

[0023] 1. The primary and secondary integrated pole-mounted switch circuit breaker and its structure are equipped with heat dissipation components to better protect the equipment body. When the axial flow fan is started, the heat generated by the power supply components is better discharged from the protective cylinder, arc groove and round hole, and finally discharged from the box through the N-shaped frame, thereby better heat dissipation and thus better protection of the equipment body.

[0024] 2. This primary and secondary integrated pole-mounted switch circuit breaker and its structure, in order to better protect the equipment body while achieving greater energy efficiency, is equipped with control components, in conjunction with rectangular blocks, stops, and bars. When the internal temperature of the enclosure rises, the metal plates bend and deform, thereby cooperating with hinge blocks, hinge rods, and insulating rods to move the movable electrode plates and insulating blocks towards the signal device and fixed electrode plates inside the L-shaped frame. This allows different groups of axial flow fans to be servo-activated according to the internal temperature of the enclosure. At the same time, the difference in cross-sectional area between the movable electrode plates and the insulating blocks generates a damping sensation, thereby ensuring that the movable electrode plates are better positioned inside the fixed electrode plates, thus achieving better protection of the equipment body while achieving greater energy efficiency.

[0025] 3. The primary and secondary integrated pole-mounted switch circuit breaker and its structure are equipped with auxiliary components to better dissipate heat. These components, along with an arc-shaped cover, heat dissipation plate, and heat dissipation holes, not only improve heat dissipation but also prevent external impurities and dust from entering the enclosure. The auxiliary components, along with an electric push rod, rectangular plate, and protrusions, allow the protrusions to clean the heat dissipation holes, thus improving heat dissipation.

[0026] 4. The primary and secondary integrated pole-mounted switch circuit breaker and its structure are equipped with protective components to further protect the equipment body. When the cable passes through the circular sleeve, the airbag deforms in conjunction with the locking block, and works with the sliding rod, circular block, clamping spring and arc strip to better adapt to cables of different outer diameters. At the same time, it prevents external impurities and dust from entering the cabinet, thereby further protecting the equipment body. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1-11 The present invention provides a technical solution:

[0041] A primary and secondary integrated pole-mounted switch circuit breaker and its structure include a housing 1, a mounting bracket 2 fixedly installed at the bottom of the housing 1, a door 3 hinged to the housing 1, a controller 4 fixedly installed inside the housing 1, a base frame 5 fixedly installed inside the housing 1, a switch body 6 fixedly installed on the top of the base frame 5, an insulator 7 fixedly installed on the switch body 6, a side frame 8 fixedly installed on the switch body 6, a top frame 9 fixedly installed inside the side frame 8, and a current transformer 10 fixedly installed inside the top frame 9.

[0042] In one embodiment of the present invention, a heat dissipation assembly 11 is provided on the housing 1. The heat dissipation assembly 11 includes an axial flow fan 111. The axial flow fan 111 is fixedly installed inside the base frame 5. A protective cylinder 112 is fixedly installed inside the switch body 6. The axial flow fan 111 is located directly below the protective cylinder 112. The protective cylinder 112 has a vertical arc-shaped groove 113 and a horizontal circular hole 114. A power supply component 115 is snapped into the inside of the protective cylinder 112. An N-shaped bracket 116 is snapped into the side wall of the housing 1. A through hole is opened in the side wall of the housing 1 at the corresponding position of the N-shaped bracket 116. In addition, the insulator 7, the axial flow fan 111, the protective cylinder 112, the power supply component 115, and the N-shaped bracket 114 are also included. The 16 is equipped with three sets of insulators 7, axial flow fans 111, protective cylinders 112, power supply components 115, and N-shaped frames 116 arranged in a linear array at equal intervals, making the layout of the equipment body more compact and reasonable. In addition, the arc grooves 113 and round holes 114 on each set of protective cylinders 112 are arranged in multiple sets, and the internal parts of the multiple sets of arc grooves 113 and round holes 114 are interconnected, thereby improving the heat dissipation effect. When the axial flow fans 111 are started, the heat generated by the power supply components 115 is better discharged from the protective cylinders 112, arc grooves 113 and round holes 114, and finally discharged from the housing 1 through the N-shaped frames 116, thereby improving heat dissipation and thus better protecting the equipment body.

[0043] In one embodiment of the present invention, a control component 12 is provided on the outside of the switch body 6. The control component 12 includes a rectangular block 121. The rectangular block 121 is fixedly installed on the bottom surface inside the housing 1. A metal sheet 122 is fixedly installed on the top of the rectangular block 121. Two sets of metal sheets 122 are provided. The two sets of metal sheets 122 are elastically deformed when heated, and the metal sheets are tightly fitted together. A hinge block 123 is fixedly installed on the top of the metal sheet 122. One end of a hinge rod 124 is hingedly installed inside the hinge block 123. An insulating rod 125 is hingedly installed on the other end of the hinge rod 124. A movable electrode sheet 126 is fixedly installed at the bottom of the insulating rod 125. The movable electrode sheet 126 is fixed on the outside. An insulating block 127 is installed. Additionally, three sets of movable electrode plates 126 and insulating blocks 127 are arranged, with the three sets of movable electrode plates 126 and insulating blocks 127 arranged vertically in an alternating pattern to prevent short circuits. Furthermore, in conjunction with rectangular blocks 121, stop blocks 1211, and stop bars 1212, when the internal temperature of the housing 1 rises, the two sets of metal plates 122 have different coefficients of thermal expansion, causing them to expand or contract at different rates, resulting in bending of the two sets of metal plates 122. This degree of bending is proportional to the temperature; therefore, the temperature can be measured by observing the degree of bending of the two sets of metal plates 122. In conjunction with hinge blocks 123 and hinge rods 124, the insulating rod 125 slides downwards inside the L-shaped frame 128. A fixed installation is mounted on the bottom surface inside the housing 1. The L-shaped frame 128 has an insulating rod 125 slidably mounted inside the top of the frame. The cross-sectional area of ​​the movable electrode plate 126 is smaller than that of the insulating block 127, which is made of rubber. The cross-sectional areas of the insulating rod 125 and the insulating block 127 are matched. A signal device 129 is fixedly mounted inside the L-shaped frame 128, and a fixed electrode plate 1210 is fixedly mounted on the signal device 129. The movable electrode plate 126 is located directly above the groove inside the fixed electrode plate 1210. In addition, there are three sets of signal devices 129, and each set of signal devices 129 has two sets of fixed electrode plates 1210. The axial flow fan 111 and the signal device 129 are electrically connected to the controller 4. A stop block 12 is fixedly mounted on the top of the rectangular block 121. 11. A baffle 1212 is fixedly installed on the outer side of the baffle 1211. Two sets of baffles 1212 are provided, symmetrically arranged at both ends of the metal sheet 122. This allows the metal sheet 122 to move more effectively, causing the movable electrode sheet 126 and the insulating block 127 to move towards the signal device 129 and the fixed electrode sheet 1210 inside the L-shaped frame 128. When the movable electrode sheet 126 enters the interior of the fixed electrode sheet 1210, different sets of axial flow fans 111 can be servo-activated according to the internal temperature of the housing 1. Simultaneously, the difference in cross-sectional area between the movable electrode sheet 126 and the insulating block 127 generates damping, ensuring the movable electrode sheet 126 is better positioned inside the fixed electrode sheet 1210.This results in better protection of the equipment itself while also being more energy-efficient.

[0044] In one embodiment of the present invention, an auxiliary component 13 is provided on the outside of the housing 1. The auxiliary component 13 includes an arc-shaped cover 131. The arc-shaped cover 131 is snapped onto the outside of an N-shaped frame 116. A heat dissipation plate 132 is snapped onto the bottom of the N-shaped frame 116. A through heat dissipation hole 133 is provided on the heat dissipation plate 132. An electric push rod 134 is fixedly installed on the top surface inside the N-shaped frame 116. The electric push rod 134 is electrically connected to a controller 4. The piston end of the bottom of the electric push rod 134 is fixedly connected to the top center of a rectangular plate 135. A protrusion 136 is fixedly installed on the bottom of the plate 135. The protrusion 136 is located directly above the heat dissipation hole 133, which improves the heat dissipation effect. Furthermore, in conjunction with the arc-shaped cover 131, heat dissipation plate 132 and heat dissipation hole 133, it can better dissipate heat, prevent external impurities and dust from entering the cabinet 1, and also provide rain and water protection. With the help of the electric push rod 134, the rectangular plate 135 and the protrusion 136 can move up and down, so that the protrusion 136 can clean the heat dissipation hole 133, thereby improving heat dissipation.

[0045] In one embodiment of the present invention, a protective component 14 is provided inside the side wall of the housing 1. The protective component 14 includes a circular sleeve 141. The circular sleeve 141 is snapped into the side wall of the housing 1. A cable passes through the inner side of the circular sleeve 141. Two sets of circular sleeves 141 are provided. A locking block 142 is fixedly installed inside the circular sleeve 141. An airbag 143 is fixedly installed outside the locking block 142. A sliding rod 144 is slidably installed in the center of the locking block 142. A circular ring block 145 is fixedly installed outside the sliding rod 144. A pressing spring 146 is fixedly installed between the circular ring block 145 and the locking block 142. The pressing spring 146 is sleeved on the outside of the sliding rod 144. In addition, an arc-shaped strip 147 is fixedly installed at the end of the sliding rod 144 away from the locking block 142. The arc-shaped outer wall of the arc-shaped strip 147 slides against the inner side of the airbag 143. The circular sleeve 141 is provided with multiple sets of locking blocks 142, airbags 143, sliding rods 144, circular ring blocks 145, and clamping springs 146. Each set of airbags 143 is provided with multiple sets of arc-shaped strips 147, and the multiple sets of arc-shaped strips 147 are arranged in a circumferential array with the center of the circular cross-section of the sliding rod 144 as the array center. Furthermore, when the cable is passed through the circular sleeve 141, the locking blocks 142 will squeeze the airbags 143, causing the airbags 143 to deform. This, in turn, allows the sliding rods 144 to slide inside the locking blocks 142, and the circular ring blocks 145 to compress and deform the clamping springs 146. This better adapts to cables of different outer diameters, ensuring that there is no gap between the cable and the circular sleeve 141, thereby preventing external impurities and dust from entering the interior of the housing 1, and further protecting the equipment body.

[0046] The primary and secondary integrated pole-mounted switch circuit breaker includes a primary and secondary integrated pole-mounted switch circuit breaker structure, and also includes an insulating pad 15. An insulating pad 15 is snapped between the bottom end of the top frame 9 and the top end of the protective cylinder 112. Multiple sets of insulating pads 15 are provided. A closing handle 16 is provided on the switch body 6, and a switch pointer 17 is provided on the switch body 6.

[0047] Working principle: When the axial flow fan 111 is started, the heat generated by the power supply component 115 is better discharged from the protective cylinder 112, the arc-shaped groove 113, and the round hole 114, and finally discharged from the housing 1 through the N-shaped frame 116, thereby improving heat dissipation and better protecting the equipment body. Furthermore, in conjunction with the rectangular block 121, the baffle 1211, and the baffle strip 1212, when the internal temperature of the housing 1 rises, the two sets of metal sheets 122 have different coefficients of thermal expansion, and they will expand or contract at different rates, causing the two sets of metal sheets 122 to bend. The degree of bending is proportional to the temperature, so the temperature can be measured by observing the degree of bending of the two sets of metal plates 122. This, combined with the hinge block 123 and hinge rod 124, allows the insulating rod 125 to slide downwards inside the L-shaped frame 128. This causes the movable electrode plate 126 and the insulating block 127 to move towards the signal device 129 and the fixed electrode plate 1210 inside the L-shaped frame 128. When the movable electrode plate 126 enters the fixed electrode plate 1210, different sets of axial flow fans 11 can be servo-activated according to the temperature inside the housing 1. 1. Simultaneously, the different cross-sectional areas of the movable electrode plate 126 and the insulating block 127 generate a damping effect, allowing the movable electrode plate 126 to be better positioned inside the fixed electrode plate 1210. This results in better protection of the device body and greater energy efficiency. Furthermore, the combination of the arc-shaped cover 131, heat sink 132, and heat dissipation holes 133 improves heat dissipation while preventing external impurities and dust from entering the housing 1, and also provides rain and water resistance. The electric push rod 134 allows the rectangular plate 135 and the protrusion 136 to move up and down, thereby enabling the protrusion 1... 36 can clean the heat dissipation holes 133, thereby improving heat dissipation. Furthermore, when the cable is passed through the circular sleeve 141, the locking block 142 will compress the air bag 143, causing the air bag 143 to deform. This, in conjunction with the arc strip 147, allows the slide rod 144 to slide inside the locking block 142. The circular block 145, in conjunction with the ring block 145, compresses and deforms the clamping spring 146, thereby better accommodating cables of different outer diameters. This ensures that there is no gap between the cable and the circular sleeve 141, preventing external impurities and dust from entering the housing 1, and further protecting the equipment body.

[0048] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
