Abstract
The invention discloses a direct-current electromagnet capable of maintaining magnetism in a power failure. The direct-current electromagnet comprises a direct-current electromagnet core, and an iron core winding is connected to a direct-current power source through a switch. The direct-current electromagnet is characterized in that two ends of the direct-current power source are parallelly connected with a reverse triggering circuit and a trigger switch, and the direct-current electromagnet core is made of a hard magnetic material.
Description
Technical field
The present invention and a kind of electromagnet, specifically the DC electromagnet of magnetic is protected in a kind of power-off.
Background technology
At present, traditional electrical magnet, when work high above the ground, has a power failure suddenly, will cause electromagnet moment demagnetization to be pounded earthward, causes danger.
Summary of the invention
The technical problem to be solved in the present invention is to provide the DC electromagnet that magnetic is protected in a kind of power-off.
In order to solve the problems of the technologies described above, the DC electromagnet of magnetic is protected in a kind of power-off of the present invention, comprises
Direct solenoid iron core, iron core winding is connected to DC power supply by switch, it is characterized in that, at the two ends of DC power supply reverse circuits for triggering in parallel, and trigger switch, described direct solenoid iron core is hard magnetic material.
Adopt the design's beneficial effect to be: when need are used electromagnet, DC power supply is powered to iron core winding, electromagnet absorption workpiece, during power-off suddenly, so because electromagnetic core is that hard magnetic material continues to keep magnetic, appoint and be so adsorbed on workpiece, can not fall down ground because of power-off electric magnet hurts sb.'s feelings, when need take off electromagnet, stir the trigger switch of reverse circuits for triggering to opposing magnetic field of electromagnet and former magnetic field cancellation, electromagnet just can take off.
Accompanying drawing explanation
Fig. 1 is that the structural representation of the DC electromagnet of magnetic is protected in a kind of power-off of the present invention.
Embodiment
The DC electromagnet of a kind of power-off of the present invention being protected to magnetic below in conjunction with the drawings and specific embodiments is described in further detail.
As shown in the figure, the DC electromagnet of magnetic is protected in a kind of power-off of the present invention, comprise direct solenoid iron core 1, iron core winding 2 is connected to DC power supply 4 by switch 3, it is characterized in that, at the two ends of DC power supply 4 reverse circuits for triggering 5 in parallel, and trigger switch 6, described direct solenoid iron core 1 is hard magnetic material.
