A primary and secondary fused pole circuit breaker

Abstract

This invention relates to the field of circuit breaker technology and discloses a primary and secondary integrated pole-mounted circuit breaker, including a mechanism box. An insulating column is fixedly connected to the top of the mechanism box, and a detector is fixedly connected to the side wall of the insulating column. To address the problem of easy wear and rust at the end of the isolating blade, an auxiliary mechanism and a pressure mechanism are set inside the device. When the arc block closes, the main friction points are concentrated on the metal probe, the arc block, the pressure plate, and the bending plate. The two components, the conductive plate and the arc block, are not initially tightly fitted together, but only in contact with each other. As the arc block continues to slide downward, the thrust generated by the spring plate forces the bending plate to push the conductive plate to press tightly against the outer surface of the conductive plate. During this movement, the actual wear points of the conductive plate and the conductive plate are concentrated at the bottom, and the rust points are also mostly concentrated in this area, effectively reducing the rust rate of other parts of the conductive plate.

Description

Technical Field

[0001] This invention relates to the field of circuit breaker technology, specifically to a primary and secondary integrated pole-mounted circuit breaker. Background Technology

[0002] The integrated primary and secondary pole-mounted circuit breaker is the core equipment in the distribution network for realizing circuit on / off control, fault protection and status monitoring. It integrates the on / off execution function of the primary equipment with the measurement, control and communication functions of the secondary equipment. It can accurately respond to the grid dispatching instructions and quickly handle line faults, playing a key role in ensuring the safe and stable operation of the distribution network and improving the reliability of power supply.

[0003] Among them, this type of circuit breaker generally uses an isolating blade to control the circuit on and off. The isolating blade and the conductive block on the insulator are mostly designed to be interlocked, with the end of the isolating blade and the conductive block on the insulator in close contact. In order to ensure the stability of current transmission, the two are in a close contact state during operation. During the closing and opening process, the end of the isolating blade will generate sliding friction with the surface of the conductive block, which can easily cause wear on the surface of the isolating blade and the conductive block, damage to the conductive coating, and corrosion of the worn parts after long-term operation, thereby reducing the conductivity stability. To address the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a primary and secondary integrated pole-mounted circuit breaker, including a mechanism box, an insulating column one fixedly connected to the top of the mechanism box, a detector fixedly connected to the side wall of the insulating column one, an isolating blade rotatably connected to the end of the detector, an insulating column two fixedly connected to the top of the mechanism box, an operating rod rotatably connected to the side wall of the mechanism box, and further including: A limiting mechanism is fixedly installed on the top of the second insulating column; the limiting mechanism includes a connecting plate fixedly connected to the top of the second insulating column, and a conductive plate is fixedly connected to the top of the connecting plate. An auxiliary mechanism is fixedly installed on the top of the connecting plate. The auxiliary mechanism includes a fixed block fixedly connected to the top of the connecting plate, and a rotating plate is rotatably connected to the inner wall of the fixed block. The pressure mechanism is fixedly mounted on the top of the connecting plate; When it is necessary to disconnect the isolating blade and the insulating post, the operator pulls the end of the operating rod downwards, and the internal connecting rod of the equipment will push the isolating blade upwards to complete the basic disconnection process.

[0005] Preferably, the limiting mechanism also includes: An isolation component is fixedly installed at the end of the isolation blade furthest from the detector. Conductive components are fixedly mounted on the side wall of the connecting plate; The side of the conductive plate two closest to the auxiliary mechanism is conductive.

[0006] Preferably, the auxiliary mechanism also includes: The push component is fixedly mounted on the top of the connecting plate; A limiting component is rotatably mounted on the inner wall of the rotating plate; The pushing component will constantly generate a thrust, forcing the rotating plate to rotate in the direction of the conductive plate two.

[0007] Preferably, the pressure mechanism includes: The snap-fit ​​assembly is fixedly mounted on the top of the connecting plate; The latching assembly limits the rotation angle of the rotating plate.

[0008] Preferably, the isolation assembly includes a metal probe fixedly connected to the end of the isolation blade away from the detector, an arc-shaped block fixedly connected to the side wall of the metal probe, and a conductive plate fixedly connected to the end of the metal probe away from the arc-shaped block. The power received by the isolation knife will be transmitted to the position of conductive plate one through the metal probe, and then to the position of the connecting plate through conductive plate two.

[0009] Preferably, the conductive component includes a protrusion fixedly connected to the side wall of the connecting plate; A plastic shell is fixedly connected to the top of the isolation blade near the isolation assembly.

[0010] Preferably, the actuating component includes a spring sheet fixedly connected to the side wall of the rotating plate; The end of the spring sheet away from the rotating plate is fixedly connected to the top of the protruding block, and the spring sheet is always in a compressed state.

[0011] Preferably, the limiting component includes a central shaft fixedly connected to the end of the rotating plate away from the fixed block, a bent plate rotatably connected to the outer wall of the central shaft, a contact plate fixedly connected to the side wall of the bent plate, and a pressure plate fixedly connected to the inclined outer wall of the bent plate. After the isolating knife completes the closing process, the contact plate will be in close contact with the side wall of the metal probe. In addition, the connection between the isolating knife and the detector is not completely tight, and the two can swing slightly. This allows the isolating knife and the isolation assembly to rotate at a small angle.

[0012] Preferably, the buckle assembly includes a limiting block fixedly connected to the top of the connecting plate, and a spring sheet two fixedly connected to the inner wall of the rotating plate; Among them, the end of the spring sheet away from the rotating plate is fixedly connected to the inner wall of the bent plate; Under normal conditions, the sidewall of the limiting block is in contact with the sidewall of the rotating plate.

[0013] The present invention has the following beneficial effects: (1) In view of the problem that the end of the isolation knife is prone to wear and rust, the present invention has an auxiliary mechanism and a pressure mechanism inside the device. When the arc block closes the circuit, the main friction points are concentrated on the metal probe, the arc block, the pressure plate and the bending plate. The two components of the conductive plate and the arc block are not tightly attached to each other at the beginning, but only in contact with each other. As the arc block continues to slide downward, the thrust generated by the spring plate will force the bending plate to push the conductive plate to stick tightly to the outer surface of the conductive plate. During this movement, the actual wear points of the conductive plate and the conductive plate are concentrated at the bottom. The rust points are also concentrated in the shadow area where the friction points are concentrated, which effectively reduces the rusting rate of the other parts of the conductive plate.

[0014] (2) The present invention utilizes the design of the above-mentioned bending plate in the normal state, where the top end is in an outward expansion position. When the isolation blade pushes the isolation component downward, the gap between the top end of the bending plate and the second conductive plate is large. This makes it possible for the larger gap to effectively guide the isolation component to close the circuit breaker if the detector and the isolation blade rust after long-term use, causing the isolation blade to swing at a large angle when closed. Through the above design, the angle of the isolation blade is effectively avoided from changing due to long-term use, which would affect the closing efficiency of ground personnel.

[0015] (3) This invention utilizes the characteristic of the bending plate driving the pressure plate to squeeze the side wall of the arc-shaped block. After the arc-shaped block is fully inserted and the bending plate pushes the conductive plate to press tightly against the side wall of the conductive plate, the pressure plate will apply pressure to the side wall of the arc-shaped block, presenting the following... Figure 11 In this state, the second spring plate is compressed, such as... Figure 10 As shown, the thrust generated by the second spring plate will force the bending plate to rotate counterclockwise around the central shaft. However, the pressure plate is in contact with the inclined side wall of the arc block. This means that the pressure generated by the second spring plate will act on the inclined side of the arc block through the pressure plate, restricting the up and down movement of the arc block. Through the above design, the isolation knife is prevented from being accidentally lifted by non-human external force during operation, ensuring the stable operation of the equipment.

[0016] (4) The present invention utilizes the above-mentioned pressure plate to apply pressure to the arc block. When the worker moves the arc block upward, the upward pressure will force the bending plate and the rotating plate to rotate counterclockwise around the fixed block through the pressure plate. At the same time, as the pressure plate and the arc block are released from their constraints, the spring plate two releases its potential energy, forcing the bending plate to rotate counterclockwise around the central shaft, reducing the force of the bending plate on the arc block. Through the above design, the friction between the conductive plate one and the conductive plate two is effectively reduced when the equipment is opened. Attached Figure Description

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.

[0021] Example 1, please refer to Figures 1-8 This invention relates to a primary and secondary integrated pole-mounted circuit breaker, comprising a mechanism box 13, an insulating column 14 fixedly connected to the top of the mechanism box 13, a detector 15 fixedly connected to the side wall of the insulating column 14, an isolating blade 16 rotatably connected to the end of the detector 15, an insulating column 17 fixedly connected to the top of the mechanism box 13, and an operating rod 18 rotatably connected to the side wall of the mechanism box 13, and further comprising: The limiting mechanism 1 is fixedly installed on the top of the insulating column 17; the limiting mechanism 1 includes a connecting plate 121 fixedly connected to the top of the insulating column 17, and a conductive plate 122 is fixedly connected to the top of the connecting plate 121. Auxiliary mechanism 2 is fixedly installed on the top of connecting plate 121. Auxiliary mechanism 2 includes a fixing block 211 fixedly connected to the top of connecting plate 121, and a rotating plate 212 rotatably connected to the inner wall of fixing block 211. Pressure mechanism 3 is fixedly installed on the top of connecting plate 121; When it is necessary to disconnect the isolating knife 16 and the insulating post 17, the operator pulls the end of the operating rod 18 downwards, and the internal connecting rod of the equipment will push the isolating knife 16 upwards to complete the basic disconnection process.

[0022] Restriction Agency 1 also includes: Isolation component 11 is fixedly disposed at the end of isolation blade 16 away from detector 15; Conductive component 12 is fixedly disposed on the side wall of connecting plate 121; The conductive plate 122 has a conductive side near the auxiliary mechanism 2, and the current received by the isolation component 11 will be transmitted to the position of the connecting plate 121 through the conductive plate 122.

[0023] Auxiliary mechanism 2 also includes: Push component 21 is fixedly mounted on the top of connecting plate 121; Limiting component 22 is rotatably disposed on the inner wall of rotating plate 212; Among them, the pushing component 21 will generate a thrust at all times, forcing the rotating plate 212 to rotate in the direction of the conductive plate 122, applying a clamping force to the isolation component 11, forcing the isolation component 11 to be tightly attached to the side wall of the conductive plate 122.

[0024] Pressure mechanism 3 includes: The snap-fit ​​assembly 31 is fixedly mounted on the top of the connecting plate 121; The buckle assembly 31 restricts the rotation angle of the rotating plate 212.

[0025] Example 2, please refer to Figures 4-11 The present invention is a primary and secondary integrated pole-mounted circuit breaker. Based on the first embodiment, the isolation component 11 includes a metal probe 111 fixedly connected to the end of the isolation blade 16 away from the detector 15, an arc-shaped block 112 fixedly connected to the side wall of the metal probe 111, and a conductive plate 113 fixedly connected to the end of the metal probe 111 away from the arc-shaped block 112. The power received by the isolation knife 16 is transmitted through the metal probe 111 to the position of the first conductive plate 113, and through the second conductive plate 122 to the position of the connecting plate 121.

[0026] The conductive component 12 includes a protrusion 123 fixedly connected to the side wall of the connecting plate 121; By utilizing the design of the bending plate 221, which is normally in an outward expansion position at its top end, when the isolating blade 16 pushes the isolating assembly 11 downward, the gap between the top end of the bending plate 221 and the conductive plate 122 is relatively large. This means that after long-term use, if the detector 15 and the isolating blade 16 become rusted, causing the isolating blade 16 to swing at a large angle during closure, the larger gap effectively guides the isolating assembly 11 to close the circuit. Through the above design, it is effectively prevented that the angle of the isolating blade 16 will change due to long-term use, thus avoiding the impact on the closing efficiency of ground personnel.

[0027] The pushing component 21 includes a spring sheet 213 fixedly connected to the side wall of the rotating plate 212; To address the issue of easy wear and rust at the end of the isolation blade 16, an auxiliary mechanism 2 and a pressure mechanism 3 are installed inside the equipment. The bending plate 221 under normal conditions is as follows: Figure 9 As shown, when the isolating blade 16 is closed, the bottom slope of the arc block 112 will first contact the top side wall of the bending plate 221. As the isolating blade 16 continues to press downward, the bottom slope of the arc block 112 will push the bending plate 221 and the rotating plate 212 to rotate outward at a small angle around the fixed block 211, so that the spring sheet 213 is deformed under pressure and accumulates potential energy.

[0028] The limiting component 22 includes a central shaft 222 fixedly connected to one end of the rotating plate 212 away from the fixed block 211, a bending plate 221 rotatably connected to the outer wall of the central shaft 222, a contact plate 223 fixedly connected to the side wall of the bending plate 221, and a pressure plate 224 fixedly connected to the inclined outer wall of the bending plate 221. The deformed spring plate 213 presses against the rotating plate 212, causing the bent plate 221 to rotate in the same direction. This forces the pressure plate 224 to press against the top of the arc-shaped block 112, making the sidewall of the conductive plate 113 tightly adhere to the sidewall of the conductive plate 122, thus completing the closing process. Through the design of the auxiliary mechanism 2 pushing the conductive plate 113 to adhere to the outer wall of the conductive plate 122, the main friction points are concentrated on the metal probe 111, the arc-shaped block 112, and the pressure plate 224 when the arc-shaped block 112 is closing. And at the position of the bending plate 221, the two components, the conductive plate 113 and the arc-shaped block 112, which are actually conductive, are not initially tightly bonded together during the bonding process; they are only in contact with each other. As the arc-shaped block 112 continues to slide downwards, the thrust generated by the spring plate 213 forces the bending plate 221 to push the conductive plate 113 tightly against the outer surface of the conductive plate 122. During this movement, the actual wear of the conductive plate 113 and the conductive plate 122 is concentrated at the bottom, such as... Figure 10 The shaded area indicated by K is where most of the rust is concentrated, effectively reducing the rusting rate of the rest of the conductive plate 122.

[0029] The buckle assembly 31 includes a limiting block 312 fixedly connected to the top of the connecting plate 121, and a spring sheet 311 fixedly connected to the inner wall of the rotating plate 212; Utilizing the characteristic of the bending plate 221 driving the pressure plate 224 to compress the side wall of the arc-shaped block 112, after the arc-shaped block 112 is fully inserted and the bending plate 221 pushes the conductive plate one 113 tightly against the side wall of the conductive plate two 122, the pressure plate 224 will then apply pressure to the side wall of the arc-shaped block 112, resulting in the following: Figure 11 The state of position G is such that, in this state, spring plate 311 is in a compressed state, as... Figure 10 As shown, the thrust generated by the second spring plate 311 will force the bending plate 221 to rotate counterclockwise around the central shaft 222. However, the pressure plate 224 is in contact with the inclined side wall of the arc block 112. This causes the pressure generated by the second spring plate 311 to act on the inclined side of the arc block 112 through the pressure plate 224, restricting the up and down movement of the arc block 112. Through the above design, the isolation knife 16 is prevented from being accidentally lifted by non-human external force during operation, ensuring the stable operation of the equipment.

[0030] One specific application of this embodiment is as follows: Before use, the mechanism box 13 is fixedly set in the required position. When it is necessary to disconnect the isolating knife 16 and the insulating column 17, the operator pulls the end of the operating rod 18 downward, and the internal connecting rod of the equipment will push the isolating knife 16 upward to complete the basic disconnection process. To address the issue of easy wear and rust at the end of the isolation blade 16, an auxiliary mechanism 2 and a pressure mechanism 3 are installed inside the equipment. The bending plate 221 under normal conditions is as follows: Figure 9 As shown, when the isolating blade 16 is closed, the bottom slope of the arc-shaped block 112 will first contact the top sidewall of the bent plate 221. As the isolating blade 16 continues to press downward, the bottom slope of the arc-shaped block 112 will push the bent plate 221 and the rotating plate 212 to rotate outward at a small angle around the fixed block 211, causing the spring sheet 213 to be deformed under pressure and accumulate potential energy. Finally, the arc-shaped block 112 will be inserted into the gap between the bent plate 221 and the conductive plate 122, presenting as shown in the figure. Figure 10 As shown, the deformed spring plate 213 presses against the rotating plate 212, causing the bent plate 221 to rotate in the same direction, and forcing the pressure plate 224 to press against the top of the arc-shaped block 112, so that the side wall of the conductive plate 113 is in close contact with the side wall of the conductive plate 122, completing the closing process. Through the design of the auxiliary mechanism 2 pushing the conductive plate 113 to fit against the outer wall of the conductive plate 122, when the arc-shaped block 112 closes, the main friction points are concentrated on the metal probe 111, the arc-shaped block 112, and the pressure plate 224. 4. At the position of the bending plate 221, the two components, the conductive plate 113 and the arc-shaped block 112, which are actually conductive, are not initially tightly bonded together during the bonding process; they are only in contact with each other. As the arc-shaped block 112 continues to slide downwards, the thrust generated by the spring plate 213 forces the bending plate 221 to push the conductive plate 113 tightly against the outer surface of the conductive plate 122. During this movement, the actual wear of the conductive plate 113 and the conductive plate 122 is concentrated at the bottom. Figure 10 The shaded area indicated by K is where friction is concentrated, and rust is also concentrated in this area, effectively reducing the rusting rate of the rest of the conductive plate 122. By utilizing the design of the bending plate 221, which is normally in an outward expansion position at its top end, when the isolation blade 16 pushes the isolation component 11 downward, the gap between the top end of the bending plate 221 and the conductive plate 122 is relatively large. This means that after long-term use, if the detector 15 and the isolation blade 16 become rusted, causing the isolation blade 16 to swing at a large angle during closure, the larger gap effectively guides the isolation component 11 to close the circuit. Through the above design, it is effectively prevented that the angle of the isolation blade 16 will change due to long-term use, thus avoiding the impact on the closing efficiency of ground personnel. Utilizing the characteristic of the bending plate 221 driving the pressure plate 224 to compress the side wall of the arc-shaped block 112, after the arc-shaped block 112 is fully inserted and the bending plate 221 pushes the conductive plate one 113 tightly against the side wall of the conductive plate two 122, the pressure plate 224 will then apply pressure to the side wall of the arc-shaped block 112, resulting in the following: Figure 11 The state of position G is such that, in this state, spring plate 311 is in a compressed state, as... Figure 10 As shown, the thrust generated by the second spring plate 311 will force the bending plate 221 to rotate counterclockwise around the central shaft 222. However, the pressure plate 224 is in contact with the inclined side wall of the arc block 112. This means that the pressure generated by the second spring plate 311 will act on the inclined side of the arc block 112 through the pressure plate 224, restricting the up and down movement of the arc block 112. Through the above design, the isolation knife 16 is prevented from being accidentally lifted by non-human external force during operation, ensuring the stable operation of the equipment. By using the pressure plate 224 to apply pressure to the arc block 112, when the operator moves the arc block 112 upward, the upward pressure will force the bending plate 221 and the rotating plate 212 to rotate counterclockwise around the fixed block 211 through the pressure plate 224. At the same time, as the pressure plate 224 and the arc block 112 are released from their restraints, the spring plate 311 releases its potential energy, forcing the bending plate 221 to rotate counterclockwise around the central shaft 222, reducing the force exerted by the bending plate 221 on the arc block 112. Through the above design, the friction between the conductive plate 113 and the conductive plate 122 is effectively reduced when the equipment is opened.
