Description

Technical Field

[0001] This utility model relates to the field of high voltage protection technology for power grids, and specifically provides a pole-mounted circuit breaker with alarm and reminder functions. Background Technology

[0002] Pole-mounted circuit breakers are the most commonly used overcurrent and short-circuit protection switches for 10kV distribution line branches and distribution transformers. Installed on 10kV distribution line branches, pole-mounted circuit breakers can reduce the scope of power outages. Because they have a disconnect point, they function as disconnecting switches, creating a safe working environment for the lines and equipment under maintenance. Pole-mounted circuit breakers are also installed on distribution transformers as the main protection for the transformers. When the current is too high or a short circuit occurs, the pole-mounted circuit breaker trips, generating an electric arc. This arc is extinguished by the vacuum interrupter, and the mechanism then disconnects the circuit, isolating the faulty section of the line or the faulty equipment.

[0003] Because pole-mounted circuit breakers are installed on high-voltage power lines, their installation position is high, making it difficult for patrol personnel to detect whether they have tripped. In other words, faulty pole-mounted circuit breakers are not easily detected due to their limited location.

[0004] Therefore, it is very meaningful to equip pole-mounted circuit breakers with an alert device so that patrolling staff can promptly identify fault points for easy maintenance. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a pole-mounted circuit breaker with alarm and reminder functions to solve the above problems.

[0006] The technical solution provided by this utility model is:

[0007] A pole-mounted circuit breaker with alarm function includes an alarm unit and a central connecting rod. The alarm unit includes an arc-blocking cylinder, a compression spring, a pressure plate, a diamond-faced crystal ball, a push-button switch, an alarm indicator light, and a fixed mounting part.

[0008] The arc-blocking cylinder is fixed to the column-mounted circuit breaker via a fixed mounting part;

[0009] The arc-isolating cylinder is a hollow cylinder with openings at both ends, and its tail end is notched.

[0010] The push-button switch is fixedly installed at the tail end of the arc-isolating cylinder, and the pressure plate is installed at the head end of the arc-isolating cylinder. The outer side of the pressure plate is connected to one end of the central connecting rod, and the other end of the central connecting rod is connected to the tip of the open / close pointer of the column-mounted circuit breaker. The compression spring and the diamond-faced crystal ball are installed inside the arc-isolating cylinder. The tail end of the compression spring is fixed to the tail end of the arc-isolating cylinder, and the head end of the compression spring is placed adjacent to the diamond-faced crystal ball. The other side of the diamond-faced crystal ball is adjacent to the inner side of the pressure plate.

[0011] The pressure plate is adapted to the inner diameter of the cylindrical arc-isolating cylinder and can move inside the arc-isolating cylinder.

[0012] The push-button switch is located at the center of the compression spring, opposite to the center of the diamond-faceted crystal ball;

[0013] The cross-sectional diameter of the central connecting rod is smaller than the inner diameter of the cylindrical arc-isolating cylinder;

[0014] The push-button switch is electrically connected to the alarm indicator light, which is mounted on the hanging bracket of the column-mounted circuit breaker.

[0015] Preferably, the on / off pointer of the column-mounted circuit breaker points from "off" to "on", thereby causing the pressure plate to move a distance within the arc-isolating cylinder that is not less than the distance from the inner center point of the diamond-faceted crystal ball to the push-button switch.

[0016] Preferably, the length of the notch is not less than the radius of the diamond-faceted crystal ball.

[0017] Preferably, the area of ​​the notch in the tail section is 1 / 3 to 2 / 1 of the circumference of the hollow cylinder.

[0018] Preferably, the alarm indicator light and the push-button switch are each equipped with a power supply module.

[0019] Preferably, the other end of the central connecting rod is connected to the tip of the open / close pointer by a rivet.

[0020] Preferably, the middle part of the fixed mounting part is arc-shaped, the arc-isolating cylinder is placed in the arc structure, and the two ends of the fixed mounting part are fixed to the main body of the column-mounted circuit device.

[0021] This utility model provides a pole-mounted circuit breaker with an alarm reminder function. By equipping the pole-mounted circuit breaker with an alarm reminder unit, patrol personnel can easily find fault points and facilitate maintenance after application.

[0022] The alarm unit does not activate when the pole-mounted circuit breaker is functioning normally. When a fault occurs, the open / close pointer turns left, causing the central connecting rod to move to the left, pushing the diamond-faced crystal ball to compress and move the compression spring inside the cylinder. The crystal ball extends out from the notch end of the cylinder. Because the surface of the crystal ball has diamond facets, it sparkles under sunlight. At the same time, the surface of the crystal ball touches and presses a small button switch, activating the self-powered alarm sound indicator light, which flashes a red light and emits a warning sound, providing a strong alarm effect and enabling patrol personnel to quickly locate the fault.

[0029] The present invention will be further explained below with reference to specific implementation schemes, but it is not limited to the present invention.

[0030] like Figures 1 to 5 As shown, this utility model provides a pole-mounted circuit device with alarm reminder function, including an alarm reminder unit 3 and a central connecting rod 4. The alarm reminder unit 3 includes an arc-blocking cylinder 301, a compression spring 302, a pressure plate 303, a diamond-faced crystal ball 305, a push-button switch 306, an alarm indicator light 307, and a fixed mounting part 308.

[0031] The arc-blocking cylinder 301 is fixed to the column-mounted circuit breaker by the fixed mounting part 308;

[0032] The arc-isolating cylinder 301 is a hollow cylinder with openings at both ends, and its tail end is notched.

[0033] The push-button switch 306 is fixedly installed at the tail end of the arc-isolating cylinder 301, and the pressure plate 303 is installed at the head end of the arc-isolating cylinder 301. The outer side of the pressure plate is connected to one end of the central connecting rod 4, and the other end of the central connecting rod 4 is connected to the tip of the open / close pointer 2 of the column-mounted circuit breaker. The compression spring 302 and the diamond-faced crystal ball 305 are installed inside the arc-isolating cylinder 301. The tail end of the compression spring 302 is fixed to the tail end of the arc-isolating cylinder 301, and the head end of the compression spring is placed adjacent to the diamond-faced crystal ball 305. The other side of the diamond-faced crystal ball 305 is adjacent to the inner side of the pressure plate.

[0034] The pressure plate 303 is adapted to the inner diameter of the cylindrical arc-isolating cylinder 301 and can move within the arc-isolating cylinder 301.

[0035] The push-button switch 306 is located at the center of the compression spring 302 and is positioned opposite to the center of the diamond-faceted crystal ball 305.

[0036] The cross-sectional diameter of the central connecting rod 4 is smaller than the inner diameter of the cylindrical arc-isolating cylinder 301;

[0037] The push-button switch 306 is electrically connected to the alarm indicator light 307, which is mounted on the hanging bracket of the pole-mounted circuit breaker.

[0038] The on-pole circuit breaker's open / close pointer 2 moves from "open" to "close", thereby causing the pressure plate 303 to move within the arc-isolating cylinder 301 by a distance not less than the distance between the inner center point of the diamond-faced crystal ball 305 and the push-button switch 306.

[0039] The length of the notch is not less than the radius of the diamond-faceted crystal ball 305. In the alarm state, the diamond-faceted crystal ball 305 is a hemispherical shape. Due to the numerous diamond facets on its surface, it sparkles under sunlight. Simultaneously, a small button switch on the left side of the crystal ball's surface is pressed, activating the self-powered alarm sound indicator 307, which flashes a red light and emits a warning sound, providing a strong alarm reminder and enabling patrol personnel to quickly locate the fault.

[0040] The area of ​​the notch in the tail section is 1 / 3 to 2 / 1 of the circumference of the hollow cylinder. The notch in the cylinder is about half the outer circumference of the crystal ball. The remaining half of the circumference is used to limit the compression spring 302 and the diamond-faced crystal ball 305 to ensure that after the fault is cleared and the circuit is closed, the compression spring 302 rebounds and the diamond-faced crystal ball 305 will not jump out of the cylinder.

[0041] The alarm indicator light 307 and the push-button switch 306 are each equipped with a power supply module.

[0042] The other end of the central connecting rod 4 is connected to the tip of the open / close pointer 2 by a rivet.

[0043] The middle part of the fixed mounting part is arc-shaped, and the arc-isolating cylinder 301 is placed in the arc structure. The two ends of the fixed mounting part are fixed to the main body of the column-mounted circuit device. The diameter of the diamond-faceted crystal ball is larger than the center diameter of the compression spring 302.

[0044] The compression spring 302 is a smaller spring in the prior art and does not require excessive elastic force. As the crystal ball 305 is squeezed, when the compression spring reaches its upper limit of contraction, the inner end of the crystal ball will pass through the center of the compressed compression spring and contact the push button switch 306.

[0045] When the pole-mounted circuit breaker is not faulty, the diamond-faced crystal ball 305 is located inside the cylindrical arc-isolating cylinder 301, where it is not exposed to sunlight or lamplight, so it will not reflect or refract light, i.e., it will not emit light. Moreover, due to the action of the compression spring, even if it is tilted, it will not touch the small push-button switch 306, and will not produce a red alarm light or warning sound.

[0046] When a fault occurs, the trip pointer of the pole-mounted circuit breaker moves from the closed position to the open position. The tip of the trip / close pointer 2 drives the central connecting rod 304 to move, and the pressure plate 303 connected to one end of the central connecting rod 4 moves accordingly. The compression spring 302 contracts under the action of the connecting rod pushing the diamond-faced crystal ball 305. The diamond-faced crystal ball 305 moves to the left along with the compressed compression spring 302 and extends out from the notch end of the cylindrical arc-isolating cylinder 301. Under sunlight or lamplight, the diamond-faced crystal ball 305 reflects and refracts light in multiple directions, and the sparkling effect provides a significant warning effect. Pressing the small push-button switch 306 on the inside of the diamond-faced crystal ball 305 connects the power supply to the alarm sound-activated indicator light 307, which starts flashing a red light and emitting a warning sound, allowing patrolling personnel to quickly find the fault point and carry out repairs.

[0047] The specific embodiments of this utility model are written in a progressive manner, emphasizing the differences between each implementation scheme, and the similar parts can be referred to each other.

[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
