Description
Technical field
The utility model relates to a kind of mains switch, especially a kind of twin-power switch.
Background technology
In electric power system, in order to guarantee the safety and reliability of power supply, often need in electric power system, configure stand-by power supply; Switching between stand-by power supply and conventional power supply needs to use twin-power switch.
Current twin-power switch form is varied.The utility model that is CN203119609U as notification number discloses a kind of double power supply automatic transfer switch, and it adopts the form driving power switch of motor and connecting rod; Notification number is that the utility model of CN201011643Y also discloses a kind of double power supply automatic transfer switch, its same form of motor and connecting rod that adopts is carried out driving switch device, but the twin-power switch operating reliability in conventional art is not high, the residing state of mains switch is stable not.
Utility model content
In order to overcome the problems referred to above of the prior art, the utility model provides a kind of twin-power switch, and it utilizes the attraction force acts of permanent magnet and magnetic metal, can improve the operating reliability of whole switch, thereby improves the fail safe of whole electric power system operation.
The scheme that the utility model adopts is: a kind of twin-power switch, comprise switch module and driver module, and described switch module comprises mains switch and mains switch slide block, described mains switch slide block is connected with described mains switch, for activating described mains switch; Described driver module comprises motor, motor gear, shaft gear, rotating shaft, rocking arm and connecting rod, described motor is connected with described motor gear, described motor gear and the engagement of described shaft gear, one end of described rotating shaft is fixedly connected with described rocking arm, described rocking arm and rod hinge connection, connecting rod and mains switch slide block are hinged; Described switch module is respectively arranged with left side permanent magnet and right side permanent magnet in the left and right sides of described mains switch slide block, in mains switch slide block, be provided with magnetic metal; Described motor can drive described rotating shaft, described rocking arm is rotated towards the direction away from described mains switch, and then rocking arm drives mains switch slide block near right side permanent magnet, magnetic metal is subject to the attraction force acts of right side permanent magnet, thereby makes described switch module reliably in the first state; Described motor can also drive described rotating shaft, described rocking arm is rotated towards the direction near described mains switch, and then rocking arm drives mains switch slide block near left side permanent magnet, magnetic metal is subject to the attraction force acts of left side permanent magnet, thereby makes described switch module reliably in the second state.
Adopt such scheme, by left side permanent magnet and right side permanent magnet are set in the left and right sides of mains switch slide block respectively, at connecting rod, with the end that mains switch slide block is connected, magnetic metal is set, improve the operational reliability of whole switch, thereby improved the fail safe of whole electric power system operation.
