Description

Technical Field

[0002] An isolating switch is an electrical device used to disconnect or connect an electrical circuit. It is typically used to isolate power sources or equipment to ensure that the circuit can be safely disconnected during maintenance, repair, or emergencies. The isolating switch's automatic tripping mechanism is a device that automatically disconnects the circuit. It is typically used to monitor faults or abnormal conditions in the circuit and automatically disconnect the circuit when necessary. The automatic tripping mechanism can trigger the circuit disconnection based on preset conditions or parameters, such as current overload or short circuit. This protects the circuit and equipment from damage and ensures the safety of personnel.

A push bar mounting groove 742 and a grounding groove 743 are separately provided. The switch knob 71 is rotatably installed in the knob rotating hole 741, and a knob connecting rod 711 is convexly provided on the bottom surface of the switch knob 71. The bottom surface of the knob connecting rod 711 is connected to the middle part of the top surface of the closing linkage piece 23. The middle part of the switch stop push bar 72 is slidably installed in the push bar mounting groove 742, and the switch stop push bar 72 is connected to the outer side of the closing card anti-slip piece 21. The middle part of the grounding conductive piece 73 is installed in the grounding groove 743.

[0041] The shielded switch housing 70 can well shield and isolate the automatic tripping mechanism and the connection circuit to prevent interference from external electromagnetic fields and electrical noise, which may lead to misjudgment and prevent the circuit from being accidentally cut off when it does not need to be disconnected.

[0042] At the same time, a control panel is provided inside the drive motor 52, which can set the thresholds of current, voltage, etc. that need to disconnect the circuit in the control panel to ensure that there will be no malfunction under normal working conditions, and the circuit can be cut off in a timely and accurate manner in the event of a fault.

[0043] For example, in one embodiment: Figure 7 , an eccentric protrusion is provided on one end of the top surface of the torsion spring fixing plate 341, please refer to Figure 5 A cam disc is convexly provided at the bottom end of the interlocking rotating sleeve 63. An opening and closing buckle is provided on the outside of the switch stop push strip 72.

[0044] For example, in one embodiment, when it is necessary to automatically connect the circuit, the drive motor 52 will be started and locked after starting, and the speed will be adjusted by the drive speed regulator 53, so that the drive output wheel 54 rotates. Since the bottom end of the eccentric connecting shaft 55 is installed on the outer edge of the top surface of the drive output wheel 54, and the top end of the eccentric connecting shaft 55 is slidably set in the drive linkage slot 364, when the drive output wheel 54 rotates, it will pull the linkage grounding plate 362 to move. Since the top end of the second energy storage linkage column 313 is penetrated by the eccentric special-shaped cam 34 and the torsion spring fixed One end of the fixed plate 341 is connected, thereby pulling the bottom end of the second energy storage linkage column 313 to move along the energy storage arc-shaped slide groove 314, causing the torsion spring fixed plate 341 to rotate, and causing the eccentric special-shaped cam 34 to rotate accordingly. Since the outer wall of the first abutting wheel 222 abuts against the outer wall of the eccentric special-shaped cam 34, the closing connection bent plate 223 and the closing crank arm 221 will follow the rotation and move, thereby causing the closing linkage piece 23 to follow the movement, causing the knob connecting rod 711 to rotate, causing the switch knob 71 to rotate, and realizing automatic circuit closing connection.

[0045] At the same time, when the torsion spring fixing plate 341 rotates, the torsion spring 33 will be compressed, and the closing linkage arc piece 241 will rotate around the first rotating shaft 122, so that the closing linkage rotating piece 242 will follow the rotation, and the linkage slide 245 will follow the movement, and then the energy storage indicator plate 64 will follow the rotation around the paddle mounting shaft 123, so that the outer wall of the energy storage indicator plate 64 will be against one end of the interlocking plate 62, fixing the interlocking plate 62. At the same time, the energy storage indicator plate 64 can be directly seen through the indicator slot 744 to indicate that power is being supplied and the torsion spring 33 is storing energy and compressing.

[0046] For example, in one embodiment: when it is necessary to manually connect the circuit, the switch knob 71 can be directly twisted, thereby causing the knob connecting rod 711 to move, causing the closing linkage piece 23 to follow and move, and then repeating the above action to achieve automatic circuit closing and connection. Subsequently, the switch stop push bar 72 can be manually pushed to move the switch stop push bar 72 inward until the switch stop push bar 72 opening and closing buckle is locked in the push bar mounting groove 742, thereby causing the closing card anti-slip piece 21 to follow and move, so that the inner side of the closing card anti-slip piece 21 is abutted against the triangular abutting plate 233, thereby locking the closing linkage piece 23 to replace the self-locking function of the drive motor 52.

[0047] For example, in one embodiment, when it is necessary to automatically cut off the circuit, the drive motor 52 will be turned off, so that the self-locking function of the drive motor 52 disappears, and the torsion spring 33 will rebound, so that the eccentric special-shaped cam 34 and the torsion spring fixing plate 341 rotate, and then the eccentric protrusion rotates accordingly, so that the cam plate moves accordingly, so that the interlocking rotating sleeve 63 rotates, and the interlocking plate 62 moves along the interlocking mounting platform 61 toward the end away from the first arc-shaped groove 111, and the energy storage indicator plate 64 rotates in the opposite direction, and the closing connection bent plate 223 and the closing crank arm 221 move in the opposite direction, so that the switch knob 71 rotates to disconnect the circuit. Simultaneously, the rotation of the torsion spring fixing plate 341 causes the second energy storage linkage column 313 to move and reset along the energy storage arcuate slot 314, causing the telescopic rod 42 to follow suit, which in turn causes the rotating crankshaft 41 to rotate accordingly, causing the adjustment gear 43 to rotate accordingly, causing the connecting gear 456 to rotate accordingly, and causing the grounding connection sleeve 452 to rotate accordingly. The top end of the grounding connection sleeve 452 abuts against the inside of the grounding bend 451 and continues to rotate with it, causing the grounding bend 451 to move outward and connect with the grounding conductive sheet 73, thereby discharging the residual current of the automatic trip mechanism. Simultaneously, the rotation of the eccentric shaped cam 34 pushes the third abutting wheel 454, causing the grounding stop bend 453 to rotate about the grounding stop shaft 457, which in turn also drives the rotating crankshaft 41 to rotate, ensuring a smooth grounding operation and instantaneous and accurate circuit disconnection.
