Description
Technical field
The utility model relates to dual-power transfer switch, is specially a kind of dual-power transfer switch.
Background technology
Dual-power transfer switch is the unnecessary loss brought to deal with unexpected power-off at Working Life, but the mains switch conversion device structure of existing dual-power transfer switch is complicated, because the defect of contact design, make dual-power transfer switch physical life low, operating environment requirements is high.
Utility model content
The technical problem that the utility model solves is to provide a kind of technical scheme, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of dual-power transfer switch, comprise wiper arm, mount pad, interlock rotating disk, described mount pad is provided with switch fixing hole and cursor installing hole, described mount pad is provided with interlock rotating disk, and the centre position of described interlock rotating disk is provided with motor shaft installing hole, and described interlock rotating disk both sides are provided with spill moving tooth, described wiper arm one end is provided with fixing hole, centre is provided with switch holddown groove, and the other end is provided with contact block and cursor, and described wiper arm is rotatably connected with the cursor installing hole on mount pad by cursor.
As preferably, the contact block in described wiper arm is arranged between the spill moving tooth of interlock rotating disk.
As preferably, described wiper arm is divided into conventional mains switch wiper arm N and Backup Power Switch wiper arm R.
As preferably, the spill moving tooth at described interlock rotating disk two ends is divided into conventional power end moving tooth N and standby electricity source moving tooth R.
Be provided with motor in the middle of described mount pad, the motor shaft of motor is connected with the motor shaft installing hole of interlock rotating disk, and described motor is connected with controller, and controller, by gathering the signals such as the voltage of conventional mains switch and Backup Power Switch, controls electric machine rotation.
A nearly step, when conventional mains switch and Backup Power Switch all have the signal of telecommunication, controller controls motor and rotates forward, and drives the spill moving tooth of interlock rotating disk to contact with the contact block of wiper arm, keep conventional mains switch to be open mode, Backup Power Switch is closed condition.
A nearly step, when conventional mains switch does not have the signal of telecommunication, when backup circuit breaker has the signal of telecommunication, controller controls motor reversal, drives the spill moving tooth of dynamic interlock rotating disk to contact with the contact block of wiper arm, drives wiper arm to rotate, conventional mains switch is closed, backup circuit breaker power supply opening.
A nearly step, when conventional mains switch and Backup Power Switch do not have the signal of telecommunication, controller does not work.
A kind of dual-power transfer switch described in the utility model, make use of lever principle cleverly, makes the conversion between conventional power supply and stand-by power supply become convenient and swift.
Beneficial effect: the utility model makes twin-power switch conversion equipment obtain great simplification, thus brings convenient for production, installs simple, substantially increases the physical life of twin-power switch simultaneously.

Embodiment
Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
A kind of dual-power transfer switch, comprise wiper arm 2, mount pad 3, interlock rotating disk 4, described mount pad 3 is provided with switch fixing hole 12 and cursor installing hole 11, described mount pad 3 is provided with interlock rotating disk 4, the centre position of described interlock rotating disk 4 is provided with motor shaft installing hole 5, described interlock rotating disk 4 both sides are provided with spill moving tooth 6, described wiper arm 2 one end is provided with fixing hole 7, centre is provided with switch holddown groove 8, the other end is provided with contact block 9 and cursor 10, and described wiper arm 2 is rotatably connected with the cursor installing hole 11 on mount pad 3 by cursor 10.
As preferably, the contact block 9 in described wiper arm 2 is arranged between the spill moving tooth 6 of interlock rotating disk 4.
As preferably, described wiper arm 2 is divided into conventional mains switch wiper arm N and Backup Power Switch wiper arm R.
As preferably, the spill moving tooth 6 at described interlock rotating disk 4 two ends is divided into conventional power end moving tooth N and standby electricity source moving tooth R.
Be provided with motor in the middle of described mount pad 3, the motor shaft of motor is connected with the motor shaft installing hole 5 of interlock rotating disk 4, and described motor is connected with controller, and controller, by gathering the signals such as the voltage of conventional mains switch and Backup Power Switch, controls electric machine rotation.
A nearly step, when conventional mains switch and Backup Power Switch all have the signal of telecommunication, controller controls motor and rotates forward, and drives the interlock spill moving tooth 6 of rotating disk 4 to contact with the contact block 9 of wiper arm 2, keep conventional mains switch to be open mode, Backup Power Switch is closed condition.
A nearly step, when conventional mains switch does not have the signal of telecommunication, when backup circuit breaker has the signal of telecommunication, controller controls motor reversal, drives the dynamic interlock spill moving tooth 6 of rotating disk 4 to contact with the contact block 9 of wiper arm 2, drives wiper arm 2 to rotate, conventional mains switch is closed, backup circuit breaker power supply opening.
A nearly step, when conventional mains switch and Backup Power Switch do not have the signal of telecommunication, controller does not work.
A kind of dual-power transfer switch described in the utility model, make use of lever principle cleverly, makes the conversion between conventional power supply and stand-by power supply become convenient and swift.
