Abstract
The utility model relates to an automatic change over switch's electromagnetic drive mechanism, including base, electro-magnet, move the iron core, two electro-magnets set up in the inside both sides of base relatively, move the iron core lower part and wear in the electro-magnet, the base forms and moves the iron core groove of iron core adaptation in the top of electro-magnet, moves the upper portion setting of iron core at the iron core inslot, moves the upper end of iron core and is connected with the extension spring, and the upper end of extension spring is connected on the base. The utility model discloses a base carries out the adaptation to the electro-magnet with moving the iron core, has improved the utilization ratio in space, has reduced the shared space of electromagnetic drive mechanism, has reduced automatic change-over switch electrical apparatus's whole volume.
Description
Technical Field
The utility model relates to an automatic change-over switch's electromagnetic drive mechanism.
Background
The automatic transfer switch electric appliance is used for switching loads of a main standby power supply switching system and a commercial power supply and a generator set in a power distribution network, the automatic transfer switch electric appliance is driven by a motor and also driven by an electromagnet, the response speed of the automatic transfer switch driven by the electromagnet is higher, but the electromagnetic driving mechanism needs two electromagnets to control the opening and closing of a common power supply and the standby power supply respectively, so that the electromagnetic driving mechanism is larger in size, and meanwhile, in order to guide a movable iron core, a guide rod needs to be arranged in the movable iron core in a penetrating mode.
Disclosure of Invention
In view of this, the present invention provides an electromagnetic driving mechanism for an automatic transfer switch, which has a compact structure and stable guiding.
In order to realize above mesh, the utility model discloses an automatic change-over switch's electromagnetic drive mechanism, including base, electro-magnet, move the iron core, two electro-magnets set up in the inside both sides of base relatively, move the iron core lower part and wear in the electro-magnet, the base forms the iron core groove with moving the iron core adaptation in the top of electro-magnet, moves the upper portion setting of iron core at the iron core inslot, moves the upper end of iron core and is connected with the extension spring, and the upper end of extension spring is connected on the base.
The utility model discloses further set up as electromagnetic drive mechanism still includes the push pedal, and push pedal one end is connected on the top of moving the iron core, and the other end extends in opposite directions.
The utility model discloses further set up to the push pedal sets up on the side of the movable iron core outside the iron core groove.
The utility model discloses further set up to the upper end of push pedal forms colludes the ring, and the lower extreme of extension spring is connected on colluding the ring of push pedal, and the extension spring passes through the push pedal and is connected with moving the iron core.
The utility model has the advantages that the movable iron core is guided through the iron core groove arranged on the base, the movable iron core is ensured not to shake outside the electromagnet, the stability of the action is improved, and the input accuracy of the push plate is ensured; move the iron core upper end and adopt the extension spring to reset, need not reset at the inside spring that sets up of electro-magnet, simple structure, convenient assembling, the utility model discloses a base carries out the adaptation to the electro-magnet with moving the iron core, has improved the utilization ratio in space, has reduced the shared space of electromagnetic drive mechanism, has reduced automatic change over switch electrical apparatus's whole volume.
