Abstract
The utility model discloses a self-holding electromagnet. The power is instantly switched on. After the utility model is turned on and turned off, the turn-on and turn-off states are still held. The original electromagnet is additionally provided with a self-holding device. The self-holding device is composed of a cylindrical permanent magnet (5) and a cylindrical permanent magnet (2) which is provided with a through hole. The cylindrical permanent magnet (5) and the cylindrical permanent magnet (2) are respectively arranged on the upper part and the lower part of an electromagnet starting coil (4), and the cylindrical permanent magnet (5) and the cylindrical permanent magnet (2) form a whole with the electromagnet starting coil (4). The utility model reduces electric the power consumption, and simultaneously increases the service life. The utility model is suitable for the traction and the braking of various mechanical devices and the connection, and is suitable for controlling the connection and the disconnection of the pipeline valve.
Description
The utility model relates to a kind of electromagnet that is suitable for traction, braking and the control pipeline valve break-make of various mechanical devices.It is relevant with the opening/shutting mode and the conduction time of electromagnet more specifically to say so.
Original technical method of electromagnet is, the electromagnet energising is opened, and outage is closed.Some electromagnetism iron rule is, the hot-wire coil excitation picks up iron core rapidly, and when iron core reached the attracted position, lance made the travel switch action, and hold-in winding makes iron core remain on attracting state with little electric current.Outage back iron core is restoring on the start position from gravity and load effect next time.The shortcoming of its existence is: when electromagnet is switched on for a long time at coil, just can be in attracting state.Electromagnet coil influences useful life because of long-term heating power, again consumed power.
The purpose of this utility model is for overcoming above-mentioned original technical shortcoming.Designed a kind of automatic holding device's of being equipped with electromagnet, i.e. electromagnet moment energising once, the iron core adhesive still keeps attracting state after the outage.Moment switches on once again, and iron core is replied on the original start position, still remains on the original start position after the outage.
Technical solution of the present utility model is to increase by an automatic holding device on electromagnet housing.The automatic holding device forms by garden column type permanent magnet with by the garden column type permanent magnet of through hole.And, install respectively in the upper and lower of electromagnet actuating coil, and form an integral body with it.
The utility model has following advantage and effect: electromagnet is owing to be equipped with the automatic holding device, and actuating coil only needs the moment energising, thereby reduces power consumption, again because coil working time weak point, and do not generate heat, increased the useful life of electromagnet, also have simple in structure, convenience operation.
Introduce the structure of utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is a utility model attracting state front view.
Fig. 2 is the original starting state front view of utility model.
With reference to accompanying drawing, on garden column type electromagnet [1], automatic holding device garden column type permanent magnet [5] is equipped with on the top of actuating coil [4].On electromagnet [1], the garden column type permanent magnet [2] that the automatic holding device has through hole is equipped with in the bottom of actuating coil [4] again.Its garden column type permanent magnet [5] is identical with the magnetic polarity opposite of the garden column type permanent magnet [2] that through hole is arranged.In detail, when giving electromagnet actuating coil [4] moment when passing to direct current, make iron core [3] produce the magnetic field of the direction that is magnetic by coil magnetization, owing to the magnetic pole of the upper magnetic pole of iron core [3] and garden post permanent magnet [5] is that the opposite sex produces attraction, the magnetic pole of the bottom of iron core [3] is the same sex with garden column type permanent magnet [2] polarity of through hole is arranged, and produces repulsive force.Thereby iron core [3] is up moved and adhesive rapidly.After actuating coil [4] outage, iron core [3] is owing to the magnetic force that garden column type permanent magnet [5] is arranged keeps attracting state, and permanent magnetism power can not down be moved iron core [3].So keep attracting state for a long time.When passing in the other direction direct current for actuating coil [4] moment, by coil magnetization, the magnetic pole that the top of iron core [3] is produced is the same sex with the magnetic pole of garden column type permanent magnet [5], and the generation repulsive force.The magnetic pole that the bottom of iron core [3] produces is the opposite sex with the magnetic pole that the garden column type permanent magnet [2] of through hole is arranged, and produces attraction.Thereby make iron core [3] down motional feedback to original start position.Behind the coil blackout, iron core [3] remains on former start position owing to the garden column type permanent magnet magnetic force of through hole is arranged at the bottom, so remain on for a long time on the original start position, waits for action next time.
Claims (2)
1, a kind of self-closing electromagnetic iron is characterized in that on garden column type electromagnet housing [1] automatic holding device being housed.And form an integral body with it.
2, electromagnet according to claim 1 is characterized in that the automatic holding device is garden column type permanent magnet [5] and the garden column type permanent magnet [2] that through hole is arranged, and installs the position, upper and lower at electromagnet actuating coil [4] respectively.
