Description

Automatic reclosing operation mechanism for dual-power transfer switch

Technical Field

The application belongs to the technical field of low-voltage switches, and particularly relates to an automatic reclosing operation mechanism for a dual-power transfer switch.

Background

Dual power transfer switches are an important device in power systems for automatic switching between a primary power source and a backup power source to ensure continuous supply of power. Such switches are typically composed of two sets of circuit breakers, connected to a main power source and a backup power source, respectively. The two groups of circuit breakers are connected through the interlocking mechanism, so that only one group of circuit breakers is switched on at any time, and the circuit problem possibly caused by simultaneous switching on of two power supplies is avoided. When the main power supply supplies power normally, the breaker of the standby power supply is opened. Once the main power supply has a power failure or other faults, the change-over switch can rapidly act to automatically cut off the circuit breaker of the main power supply and simultaneously start the circuit breaker of the standby power supply so as to ensure that the power supply is not interrupted. The automatic switching function greatly improves the reliability and stability of the power system. In short, the dual power transfer switch monitors the state of the power supply at all times, so as to ensure smooth power supply.

The automatic reclosing operation mechanism is an important component part in the dual-power transfer switch, and the main function of the automatic reclosing operation mechanism is to automatically switch the electric load from the main power supply to the standby power supply after the main power supply fails or is powered off. This process is automated and does not require manual intervention, thereby ensuring the continuity of the power supply. The automatic reclosing operation mechanism has the following functions: 1. monitoring and judging: the operating mechanism continuously monitors the status of the primary power source. The mechanism will immediately initiate the switching procedure upon detection of a mains power failure or power outage. 2. Switching operation: after confirming the failure of the main power supply, the operating mechanism rapidly cuts off the circuit breaker of the main power supply and simultaneously starts the circuit breaker of the standby power supply. This is accomplished by a motor driven mechanical transmission mechanism that ensures that both sets of circuit breakers are not in conduction at the same time. 3. Reclosing process: when the main power supply is recovered to be normal, the automatic reclosing operation mechanism can also perform automatic reclosing operation according to preset conditions and logic judgment, namely, the load is switched back to the main power supply for power supply.

However, the existing dual-power reclosing operation mechanism is positioned between the main power switch group and the standby power switch group, and has slower automatic switching operation and improvement.

The working principle of the embodiment of the application is that: when the standby power switch group 2 performs switching-on action, the linkage rod II 4 drives the interlocking sliding handle II 611 to rotate clockwise (refer to fig. 7), the jump button II 617 is pushed and the lock catch II 613 is driven to rotate clockwise, the poking piece II 615 pokes the jump rod 709 in the breaker sub-body adjacent to the interlocking mechanism 6 in the main power switch group 1 to perform switching-off action, the linkage rod I3 drives the whole main power switch group 1 to perform switching-off action, meanwhile, the linkage rod I3 drives the interlocking sliding handle I603 to rotate anticlockwise, the jump button I609 is pushed to rotate anticlockwise, after the action is completed, the tension spring II 616 controls the lock catch II 613 to reset, and the torsion spring I610 controls the jump button I609 to reset; when the main power switch group 1 performs a switching-on action, the linkage rod I3 drives the interlocking sliding handle I603 to rotate clockwise (refer to fig. 7), the jump buckle I609 is pushed and drives the lock buckle I605 to rotate clockwise, the poking piece I607 pokes the jump rod 709 in the breaker sub-body adjacent to the interlocking mechanism in the standby power switch group 2 to perform a switching-off action, the linkage rod II 4 drives the whole standby power switch group 2 to perform a switching-off action, meanwhile, the linkage rod II 4 drives the interlocking sliding handle II 611 to rotate anticlockwise, the jump buckle II 617 is pushed to rotate anticlockwise, after the action is completed, the tension spring I608 controls the lock buckle I605 to reset, and the torsion spring II 618 controls the jump buckle II 617 to reset.

In the embodiment of the application, the interlocking mechanism is arranged and matched with the first linkage rod 3 and the second linkage rod 4, so that the interlocking linkage of the main power switch group 1 and the standby power switch group 2 is realized, when the main power switch group is switched on, the standby power switch group immediately completes the switching-off action, when the standby power switch group is switched on, the main power switch group immediately completes the switching-off action, the switching-off action feedback is immediate, and the rapidity of double power conversion is improved; through setting up operating device, the motor direct drive main power switch group and stand-by power switch group have improved the degree of automation of dual power conversion.

The invention and its embodiments have been described above schematically, without limitation, and the drawings illustrate only one embodiment of the invention and the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical scheme are not creatively devised without departing from the gist of the present invention, and all the structural manners and the embodiment are considered to be within the protection scope of the present invention.
