Embodiment
Be described further referring to figs. 1 through 3 pairs of power-actuated twin-power switch embodiments of the utility model electromagnetism.
The power-actuated twin-power switch of a kind of electromagnetism, comprises main power source wire 1, stand-by power supply wire 2, current output terminal 3, switch contact 4, main electromagnet 5, secondary electromagnet 6, main converter 7, secondary rectifier 8, rotating shaft 9, permanent magnet 10, contact hold down gag 11 and conductive contact 12.
As shown in Figure 1, main power source wire 1 is divided into two strands, and wherein one end is installed with leading electrical contact 12, is also provided with contact hold down gag 11 dorsad herein.(this contact hold down gag 11 is holddown spring in this embodiment.) another stock of main power source wire 1 is connected to main converter 7, the AC conversion provided by main power source by main converter 7 is direct current and passes in main electromagnet 5, makes it produce constant magnetic field, a size direction.Stand-by power supply wire 2 is also divided into two strands, and same wherein one end is installed with secondary conductive contact 13, is also provided with contact hold down gag 11 herein.(this contact hold down gag 11 is holddown spring in this embodiment.) another stock of stand-by power supply wire 2 is connected to secondary rectifier 8, the AC conversion provided by stand-by power supply by secondary rectifier 8 is direct current and passes in secondary electromagnet 6, makes it produce constant magnetic field, a size direction.The magnetic field that main electromagnet 5 produces be greater than secondary electromagnet 6 produce magnetic field and the S pole-face opposite of the S pole of main electromagnet 5 and secondary electromagnet 6 be horizontally disposed with.(two electromagnet are made to produce the magnetic force of different size by changing the coil turn that main electromagnet 5 and secondary electromagnet 6 are wound around in the present embodiment, also can for a change size of iron core in coil, change and pass into the means such as the size of current of electromagnet and realize this effect.Setting for the magnetic pole of main electromagnet 5 and secondary electromagnet 6 also can be that the N pole-face opposite of 2 magnet is arranged.）
In the present embodiment, between major and minor electromagnet, be provided with the permanent magnet 10 be connected with rotating shaft 9, the N pole of permanent magnet 10 upper, S pole under.Current output terminal 3 is fixed with at the N pole place of permanent magnet 10, the switch contact 4 that can match with leading electrical contact 12 and secondary conductive contact 13 when (if the N pole-face opposite of two electromagnet is arranged, then the pole orientation of permanent magnet 10 need make corresponding change) is provided with rotation on current output terminal 3.At the dorsal part of leading electrical contact 12, contact hold down gag 11 is installed, same is also provided with contact hold down gag 11 at the dorsal part of secondary conductive contact 13, and this contact hold down gag 11 is holddown spring (contact hold down gag 11 also can have the parts of substrate hold-down function for other) in the present embodiment.
When main power source wire 1 is energized, the magnetic produced due to main electromagnet 5 is greater than the magnetic that secondary electromagnet 6 produces, now permanent magnet 10 will be rotated counterclockwise around rotating shaft 9 by carrying electrical current output 3, until the switch contact 4 on current output terminal 3 contacts with leading electrical contact 12.Namely the effect that main power source is communicated with is completed, as shown in Figure 2.When making main power source road disconnect due to accident, main electromagnet 5 owing to there is no galvanization so lose magnetic, now because stand-by power supply still has electricity, secondary electromagnet 6 still produces magnetic force, permanent magnet 10 is just under the effect of the elastic force of holddown spring and the magnetic force of secondary electromagnet 6, carrying electrical current output 3 turns clockwise, until the switch contact 4 on current output terminal 3 contacts with secondary conductive contact 12, as shown in Figure 3.Namely switch is automatically switched to stand-by power supply function by main power source is completed.
The above is preferred implementation of the present utility model, under not departing from the prerequisite of the utility model principle to those skilled in the art, can also make some modification and improvement, and these also should be considered as this and use novel protection range.
