Description

Technical Field

[0001] The utility model relates to the field of circuit breaker equipment, in particular to an insulating component of a circuit breaker. Background Technique

[0002] A circuit breaker is an important switching device in a power system. Circuit breakers are divided into two categories. One is used on high-voltage power poles, and the other is used in large-scale power consumption places such as factories. The circuit breakers used in factories can close, carry, and break the current under normal circuit conditions. At the same time, they can also close, carry, and break the current under abnormal circuit conditions within a specified time. The insulating component plays a crucial role in the power system. Its main function is to ensure the safe operation of power equipment and lines. At the same time, it also plays a protective role for the circuit breaker, preventing faults such as current leakage and short circuits.

[0003] The insulating component of the circuit breaker used in factories is basically composed of multiple insulating columns. The multiple insulating columns are respectively arranged between the circuit breaker substrate and the circuit breaker to prevent direct electrical contact between the circuit breaker and the circuit breaker substrate, so as to ensure that the circuit breaker will not be electrically interfered by the circuit breaker substrate or other adjacent equipment during operation. The circuit breaker substrate refers to the patent with the publication number CN215069836U, and the circuit breaker model is the VS1-24 circuit breaker of Haineng Electric Company. The existing installation method of the insulating column on the circuit breaker substrate is basically through self-tapping screws. The staff uses tools to tighten the self-tapping screws to install the insulating column on the circuit breaker substrate to prevent direct electrical contact between the circuit breaker and the circuit breaker substrate. At the same time, in some small circuit breakers, there is an installation method of using special glue to adhere the insulating column. The method of adhering the insulating column requires the staff to manually hold the insulating column for a certain period of time to ensure that the glue solidifies and ensure the firmness between the insulating column and the circuit breaker substrate. The above two installation methods make the installation process of the insulating column relatively cumbersome, which reduces the work efficiency of the staff to a certain extent.

[0004] Therefore, it is necessary to provide a new insulating component of a circuit breaker to solve the above technical problems. Content of the Utility Model

The outer surfaces of the three support blocks are movably connected to the inner surface of the movable groove. One side of the three support blocks away from the three trapezoidal blocks is respectively fixedly connected to one side of the three arc-shaped blocks.

[0009] Preferably, the jacking component includes a conical column. The conical column is movably arranged inside the conical groove. The bottom of the conical column is fixedly connected to a connecting block. The side of the connecting block away from the conical column is fixedly connected to one side of the power mechanism.

[0010] Preferably, a power ring is movably sleeved on the outer surface of the three support blocks close to one side of the three arc-shaped blocks. The inner surface of the power ring is respectively movably connected to the outer surfaces of the three arc-shaped blocks.

The side of the transmission part away from the power ring is fixedly connected to the side of the power mechanism close to the connecting block.

[0011] Preferably, the transmission part includes a transmission block. One side of the transmission block is fixedly connected to one side of the outer surface of the power ring.

The three trapezoidal blocks 4 are in complete fit with the annular shape of the insulating column 3, completing the limitation of the insulating column 3 and completing the installation of the insulating column 3.,

[0028] The working principle provided by the present utility model is as follows: The staff moves the insulating column 3 towards the three trapezoidal blocks 4. At the same time, the insulating column 3 drives the three trapezoidal blocks 4 to move relatively through the inclined surfaces of the three trapezoidal blocks 4. At the same time, the three trapezoidal blocks 4 drive the three arc-shaped blocks 6 to retract through the three support blocks 8. The three arc-shaped blocks 6 drive the connecting block 10 to move downward through the conical column 9 inside the conical groove 7. At the same time, the connecting block 10 drives the power block 14 to retract through the movable plate. The movable block 13 applies kinetic potential energy to the spring 15, driving the spring 15 to be in a compressed state. When the three trapezoidal blocks 4 completely enter the annular groove 5 of the insulating column 3, the insulating column 3 will release the drive on the three trapezoidal blocks 4. At the same time, the three trapezoidal blocks 4 release the drive on the three arc-shaped blocks 6 through the three support blocks 8. The three arc-shaped blocks 6 release the drive on the movable block 13 through the conical column 9 and the connecting block 10, enabling the movable block 13 to release the kinetic potential energy applied to the spring 15. The spring 15 starts to release kinetic potential energy, and the spring 15 performs an extension movement. The spring 15 drives the power block 14 to extend through the movable block 13. At the same time, the movable block 13 drives the conical column 9 to move through the connecting block 10, causing the conical column 9 located inside the conical groove 7 of the three arc-shaped blocks 6 to move upward, enabling the conical column 9 to drive the three arc-shaped blocks 6 to move in the opposite direction. The three arc-shaped blocks 6 drive the three trapezoidal blocks 4 to move in the opposite direction through the three support blocks 8, causing the three trapezoidal blocks 4 to expand. The three trapezoidal blocks 4 are completely fitted with the annular shape of the insulating column 3, completing the limiting of the insulating column 3. The staff can then complete the installation of the insulating component of the circuit breaker. When it is necessary to disassemble the insulating column 3, the staff applies pressure to the power block 14, causing the power block 14 to drive the movable plate to move downward, causing the movable plate to apply kinetic potential energy to the spring 15, driving the spring 15 to be in a compressed state. The movable plate drives the conical column 9 to move downward through the connecting block 10, releasing the drive of the conical column 9 on the three arc-shaped blocks 6. At the same time, the movable block 13 drives the power ring 11 to move downward through the transmission block 12, enabling the power ring 11 to drive the three arc-shaped blocks 6 to move relatively through the inclined surfaces of the three arc-shaped blocks 6. At the same time, the three arc-shaped blocks 6 drive the three trapezoidal blocks 4 to move to the relative side through the three support blocks 8, causing the three trapezoidal blocks 4 to retract, releasing the fitting of the three trapezoidal blocks 4 with the annular groove 5 of the insulating column 3, releasing the limiting of the insulating column 3. The staff can directly remove the insulating column 3, and the staff can then replace the insulating component of the circuit breaker.
