Problems solved by technology

However, if there is no corresponding dual power supply switching device to ensure that the switching between the two power sources is completed within one power frequency cycle, even if the configuration of dual power sources is adopted, it will not be able to achieve continuous power supply in the true sense.

Abstract

The invention discloses a double power switching operation mechanism and an operation method. Current technologies often fail to ensure the completion of switching between a main power supply and a backup power supply within one power frequency period, and often can not provide continuous power supply in reality. According to the invention, the operation mechanism includes: a support 1 which is provided with an excitation coil 2, the excitation coil being provided with an armature 3, the armature 3 being in mechanical connection to a transmission tooth bar 5 through a connection lever 4, the transmission tooth bar engaging a lock gear 6, the lock gear being fixed to the bottom disc 11 of the support through a lower end of a lock gearshaft. According to the invention, the operation mechanism and the operation method are applied to double power supply switching operation in scenarios which require continuous power supply.

Description

technical field [0001] The invention relates to the automatic switching of dual power supply for smart grid, in particular to a dual power switching operating mechanism and an operating method. Background technique [0002] With the advancement of science and technology, industrial production and people's lives have higher and higher requirements for the continuity and reliability of power supply systems. Due to the increasing operating load of the power grid, more and more line faults are caused, and phenomena such as phase loss, undervoltage, and overcurrent occur frequently. Therefore, it is necessary to use two independent dual power supply lines of main and backup to supply power to important users such as airports, firefighting, hospitals, and military, so as to ensure the continuity and reliability of power supply. However, if there is no corresponding dual power supply switching device to ensure that the switching between the two power sources is completed within on...
