Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, and in particular to a disconnector and an automatic tripping mechanism. Background Art

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

The middle part of the grounding conductive sheet 73 is installed in the grounding groove 743.

[0043] 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 without disconnection.

[0044] At the same time, a control panel is provided inside the drive motor 52, and the thresholds of current, voltage, etc. that need to disconnect the circuit can be set 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.

[0045] For example, in one embodiment: See 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 plate is convexly arranged at the bottom end of the interlocking rotating sleeve 63. An opening and closing buckle is arranged on the outer side of the switch stop push strip 72.

[0046] For example, in one embodiment, when the circuit needs to be automatically connected, 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 arranged in the drive linkage slide groove 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 groove 314, and causing the torsion spring fixed plate 341 to rotate, and causing the eccentric special-shaped cam 34 to follow the rotation. 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, and then the closing linkage piece 23 will follow the movement, causing the knob connecting rod 711 to rotate, causing the switch knob 71 to rotate, and realizing automatic circuit closing connection.

[0047] 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 sliding column 245 will follow the movement, and then the energy storage indicating plate 64 will follow the rotation around the paddle mounting shaft 123, so that the outer wall of the energy storage indicating plate 64 will be against one end of the interlocking plate 62 to fix the interlocking plate 62. At the same time, the energy storage indicating plate 64 can be directly seen through the indicating groove 744 to indicate that power is being supplied and the torsion spring 33 is storing energy and compressing.

[0048] For example, in one embodiment: when it is necessary to manually connect the circuit, the switch knob 71 can be directly twisted, thereby making the knob connecting rod 711 move, so that the closing linkage piece 23 moves accordingly, and then repeating the above-mentioned action to realize automatic closing and connection of the circuit. Subsequently, the switch stop push bar 72 can be manually pushed to move the switch stop push bar 72 inward until the opening and closing buckle of the switch stop push bar 72 is locked in the push bar mounting groove 742, thereby making the closing card anti-slip piece 21 move accordingly, so that the inner side of the closing card anti-slip piece 21 abuts against the triangular abutting plate 233, thereby locking the closing linkage piece 23 to replace the self-locking function of the drive motor 52.

[0049] 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, so that 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 away from the end of the first arc-shaped groove 111, and the energy storage indicating 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 cut off the circuit. At the same time, the rotation of the torsion spring fixing plate 341 will cause the second energy storage linkage column 313 to move and reset along the energy storage arc slot 314, so that the telescopic rod 42 moves accordingly, so that the rotating crankshaft 41 rotates accordingly, so that the adjusting gear 43 rotates accordingly, so that the connecting gear 456 rotates accordingly, so that the grounding connection sleeve 452 rotates accordingly, so that the top end of the grounding connection sleeve 452 abuts against the inner side of the grounding bent plate 451 and continues to rotate with it, so that the grounding bent plate 451 moves outward, so that the grounding bent plate 451 is connected to the grounding conductive sheet 73, and the residual electricity of the automatic tripping mechanism is led out. At the same time, the rotation of the eccentric special-shaped cam 34 will push the third abutting wheel 454, so that the grounding stop bent plate 453 rotates around the grounding stop shaft 457, and then it will also push the rotating crankshaft 41 to rotate, so as to ensure the smooth grounding operation and the instantaneousness and accuracy of the circuit cut-off.
