Abstract

The invention relates to an electric element, in particular to a lockable electromagnet. An electromagnet armature of a device is locked by an auxiliary electromagnet armature or is unlocked when the electromagnet armature is moved. During work doing of the device, an electromagnet coil 2 is not powered on and does not consume electric power and an auxiliary tension electromagnet 6 also does not consume electric power, but an electromagnet still does work, and only in an instant when the electromagnet coil attracts the electromagnet armature to move, a very small amount of electric energy is consumed. Or during work doing, the electromagnet coil 2 is not powered on, and an auxiliary thrust electromagnet 7 only consumes a very small amount of electric energy, and then 16VA of the auxiliary thrust electromagnet 7 replaces 437 VA of the electromagnet coil 2. But the electromagnet still does work, and only in the instant when the electromagnet coil 2 attracts the electromagnet armature 3 to move, a very small amount of electric energy is consumed. The same work is done by using the electromagnets with the same size, over 90 percent of electricity is saved, and energy resources are saved.

Description

A kind of electromagnet that pins

Technical field

The present invention relates to a kind of electric component, especially electromagnet.

Background technology

At present, electromagnet converts electromagnetic energy into the electric component of mechanical energy in automatic control system, can also in elevator, tower crane, contactor, circuit breaker, relay, use very extensive as parts of electrical equipment.Be divided into traction, braking, valve by its effect and use etc., after its operation principle was coil electricity, iron core produced suction, attracted armature motion, drove mechanical device motion acting, work done therebetween coil must continue energising, power consumption is very big, wastes very much electric energy.

Summary of the invention

The technical problem that invention will solve is, the electromagnet of a kind of consumption electric energy seldom is provided, and can replace present widely used electromagnet.

For achieving the above object; Technical scheme that the present invention adopts is: the electromagnet of mainly being made up of iron core, coil, armature that pins; Auxiliary selenoid retort stand and electromagnet armature are in the same side; The direction of motion of auxiliary selenoid retort stand and electromagnet armature is parallel, and subsidiary magnet is installed on the auxiliary selenoid retort stand, and the direction of motion of subsidiary magnet armature is vertical with the direction of motion of electromagnet armature; Electromagnet coil power during the electromagnet armature motion, has by the pinning of subsidiary magnet armature, release two states; When electromagnet armature is lockable, the electromagnet coil no power, electromagnet is work done still; Electromagnet armature is unlocked, when setting back, and not work done of electromagnet.

During the electromagnet armature motion, when assisting pulling force electromagnet armature original position, pin electromagnet armature; When auxiliary pulling force electromagnet armature moves, releasing magnet armature, electromagnet armature sets back.When perhaps electromagnet armature moves, when the augmented thrust electromagnet armature also moves, pin electromagnet armature; When the augmented thrust electromagnet sets back, releasing magnet armature, electromagnet sets back.The position that electromagnet armature is lockable is in recess or the through hole or platform or groove.

Technical scheme of the present invention, non-obvious.The present technique scheme is compared with prior art, can produce tangible beneficial technical effects.The shortcoming of known electromagnet is, electromagnet work done therebetween coil must continue energising, the waste electric energy.And present technique scheme electromagnet coil no power during work done, consumed power not, auxiliary pulling force electromagnet be consumed power not also, but electromagnet still does work, and just attracts the moment of electromagnet armature motion at electromagnet coil, consumes electric energy seldom.Perhaps electromagnet coil no power during work done, the augmented thrust electromagnet only consumes little electrical energy, but electromagnet still does work, and just attracts the moment of electromagnet armature motion at electromagnet coil, consumes electric energy seldom.

Technical scheme of the present invention, non-obvious.Owing to adopted such scheme, during the electromagnet armature motion, have by the structure of the pinning of subsidiary magnet armature, release two states, with onesize electromagnet, same acting, economize on electricity has been practiced thrift the energy more than 90%.Therefore the present invention has outstanding substantive distinguishing features and obvious improvement.
