Description

Technical Field

[0001] The invention belongs to the technical field of circuit breakers, and in particular relates to a circuit breaker with a power-taking capacitor. Background Art

[0002] A pole-mounted circuit breaker is a circuit breaker device installed on an overhead line pole. The pole-mounted circuit breaker can effectively protect the line. When a short circuit occurs in a certain section of the line, the pole-mounted circuit breaker will trip quickly to prevent the impact of the fault from expanding and ensure the normal power supply of other users. For example, the patent with announcement number CN220604562U proposes a primary and secondary integrated digital pole-mounted circuit breaker, which realizes a deep integration of primary and secondary physical spaces, ensuring the miniaturization of the product and the convenience of installation.

[0003] When the circuit breaker is in use, in order to ensure that the circuit breaker can work normally when there is a brief interruption or fluctuation in the power supply, some pole-mounted circuit breakers will be equipped with power-taking capacitors on the surface to provide temporary power to the control circuit of the circuit breaker to keep it in its current state. The power-taking capacitor can also help smooth the ripple and noise in the power supply, improve the power quality, make the voltage input to the circuit breaker control circuit more stable and pure, and reduce interference to the control circuit.

[0004] Since pole-mounted circuit breakers are usually set up outdoors for operation, and the components inside the pole-mounted circuit breakers will generate high temperatures when working, the long-term operation of the power-taking capacitor under high temperature conditions will accelerate the evaporation of the internal electrolyte, leading to drying up. In addition, as the capacitor is used for a long time, the electrolyte will gradually wear out naturally and may eventually dry up. The electrolyte is an important medium for capacitors to store charge. Drying up will cause the amount of charge that the capacitor can store to decrease, so that the actual capacity of the capacitor is lower than the nominal capacity. It is difficult for operators to detect the internal changes of the power-taking capacitor in time, and they cannot replace the power-taking capacitor in time, which affects the performance of the power-taking capacitor.

[0005] In addition, the pole-mounted circuit breaker needs to be used in conjunction with the aviation plug. After the aviation plug is used for a long time, the internal sealing ring may age, crack or deform, resulting in a decrease in the sealing performance. Moisture and impurities can easily enter the plug, causing a short circuit or damage to internal components.

[0048] The lower side wall of the threaded barrel 23 is fixedly connected with a guide slide 52, and the inner wall of the working box 211 is fixedly connected with a guide slide rod 32 that slides with the guide slide 52, which can prevent the threaded barrel 23 from rotating and enable the threaded barrel 23 to move left and right only in the horizontal direction.

[0049] The operating principle of the present invention is now described as follows: insert the plug 261 into the outside of the socket 53, insert the pin 27 inside the plug 261 into the socket 53, then connect the air outlet of the air pump 30 to the lower end of the elbow 31 through a threaded connection, and then send a control signal to the PLC controller 9 through an external button. After receiving the control signal, the PLC controller 9 first controls the external current to be transmitted to the conductive block 37. At this time, the conductive block 37 is in contact with the conductive plate 38, and the conductive plate 38 is electrically connected to the air pump 30. When the external current is transmitted to the conductive block 37, The current will be transmitted to the air pump 30 through the conductive plate 38, so that the air pump 30 starts to work. The air pump 30 transmits the helium in the gas tank 29 to between the insert 261 and the socket 53, so that the gas in the insert 261 is discharged through the exhaust pipe 33. After the air pump 30 has worked for thirty seconds, the PLC controller 9 will control the solenoid valve 34 to close, and the air pressure inside the insert 261 will continue to increase. The helium will enter the air pressure box 352 through the short tube 351, so that the air pressure in the space above the piston plate 36 increases. Under the push of the air pressure, the piston plate 36 will drive the conductive block 37 to move downward together until the conductive block 37 and the conductive block 37 are in contact with each other. When the electric contact block and the trigger plate 42 are in contact, the PLC controller 9 controls the micro electric push rod 39 to drive the trigger switch 40 to move downward to the set position, and then the PLC controller 9 controls the electric contact block and the external power supply to disconnect. When the sealing ring inside the plug 261 loses its sealing performance due to aging, the gas inside the plug 261 is The gas will be discharged along the crack of the sealing ring, and the gas inside the air pressure box 352 will also be discharged, so that the air pressure in the space above the piston plate 36 is reduced. The piston plate 36 will slowly move upward under the elastic force of the spring until the piston plate 36 squeezes the trigger switch 40, and the trigger switch 40 will send an electrical signal to the PLC controller 9. After receiving the electrical signal, the PLC controller 9 will control the buzzer 41 to work, reminding the power personnel that the sealing ring on the inner wall of the plug 261 needs to be replaced. The micro electric push rod 39 can then retract to the initial position under the control of the control switch 43;

[0050] When the solenoid valve 34 is closed, the gas inside the insert 261 will be transported to the vertical cylinder 44 through the horizontal pipe 45, so that the air pressure in the space below the piston seat 46 increases. The piston seat 46, under the push of the air pressure, will drive the positioning pin 47 to move upward, so that the positioning pin 47 passes through the positioning hole 51 and is inserted into the positioning groove 50 on the surface of the limiting plate 49, so as to relatively fix the horizontal cylinder 48 and the limiting plate 49 (after the insert 261 and the socket 53 are plugged in, the limiting plate 49 will be inserted into the horizontal cylinder 48), thereby increasing the connection stability between the insert 261 and the socket 53;

[0051] Then, the two power-taking capacitor bodies 4 are placed in the two installation tubes 501 respectively, and then the cover plate 502 is fixedly connected to the upper surface of the installation tube 501 by bolts, and then the water pump 112 is controlled to work through the externally connected control interface, and the water pump 112 transports the coolant in the water tank 111 to the spiral tube 13 on the right through the delivery pipe 12. At this time, the two first control valves 19 are in an open state, and the two second control valves 20 are in a closed state. When the coolant flows from the spiral tube 13, it will take away the heat generated by the power-taking capacitor body 4 on this side and transport it to the serpentine tube 16, and the heat will be discharged to the surrounding air through the heat dissipation frame 15 arranged outside the serpentine tube 16;

[0052] When the electrolyte inside the power-taking capacitor body 4 dries up due to long-term use, the shell of the power-taking capacitor body 4 will swell due to the imbalance of internal pressure, thereby squeezing the vertical plate 7 on this side, and the vertical plate 7 will move into the horizontal groove 6 to squeeze the push switch 8 in the horizontal groove 6. The push switch 8 will transmit an electrical signal to the PLC controller 9. After receiving the electrical signal, the PLC controller 9 first controls the indicator light 10 on the right to light up, so that the power personnel can replace the power-taking capacitor body 4 on the right in time when they overhaul the equipment later. Then the PLC controller 9 controls the two first control valves 19 to close, and controls the two second control valves 20 to close. Refer to the above According to the above principle, the left power-taking capacitor body 4 will be cooled. At the same time, the PLC controller 9 will also control the servo motor 22 to rotate in the forward direction to the set time. The servo motor 22 will drive the threaded rod 212 to rotate, and the threaded barrel 23 will move through the threaded cooperation. The threaded barrel 23 drives the two metal plates 24 to move through the bracket, so that the metal plate 24 that is in contact with the metal block 25 in the initial state on the right side is removed, and the metal plate 24 on the left side is in contact with the metal block 25. The metal block 25 is connected to the circuit inside the circuit device body, and the metal plate 24 on the left side is connected to the internal circuit of the power-taking capacitor body 4 on the left side, so that the power-taking capacitor body 4 on the left side is connected to the circuit device body to work.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
