Embodiment
For clearer statement the utility model, the utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the utility model structured flowchart, and the utility model provides a kind of novel charged locking device, is made up of voltage conversion device and electromagnetic mechanism, and voltage conversion device is connected with electromagnetic mechanism.Electromagnetic mechanism is made of solenoid and magnet, and solenoid is wound in the outside of magnet, and voltage conversion device is adaptation, under-voltage device or rectifier, and magnet is permanent magnet or electromagnet.
Fig. 2 is the utility model example structure block diagram, and the utility model provides a kind of novel charged locking device, is made up of voltage conversion device and electromagnetic mechanism, and voltage conversion device is connected with electromagnetic mechanism.Electromagnetic mechanism is made of solenoid and magnet, and solenoid is wound in the outside of magnet, and voltage conversion device is adaptation, under-voltage device or rectifier etc., and magnet is permanent magnet or electromagnet.Voltage conversion device is connected with the voltage transformer of outside, and electromagnetic mechanism is connected with the transmission mechanism of outside.The structure of voltage transformer can adopt three single-phase designs or a three-phase design, and transmission mechanism can adopt iron, metal bolt, metal baffle, iron gate or action bars.
The three-phase high voltage of being supplied with by mains side is converted to low pressure and transmits to voltage conversion device by lead through voltage transformer, is converted to two-phase voltage through voltage conversion device, and to meet the use standard of electromagnetic mechanism, electromagnetic mechanism drives transmission mechanism and realizes locking.On the low-pressure side of voltage transformer and the transmission line between the voltage conversion device, be provided with insurance unit and power monitoring lamp, to guarantee the operate as normal of circuit.
Operation principle of the present utility model is: when mains side did not have electricity, because magnet do not produce magnetic field and transmission mechanism can't be held, so operating personnel can operate the ground connection disconnecting link; When mains side was charged, the magnetic field that coil produces held transmission mechanism, thereby transmission mechanism can't be operated the ground connection disconnecting link, with the person, equipment or the accident of power supply of avoiding causing owing to misoperation ground connection disconnecting link.
More than disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection range of the present utility model.
