Abstract
The utility model belongs to the electric appliance class, and relates to a novel alternating current electromagnet. The utility model is mainly composed of an iron core, an electromagnetic coil, an armature iron, and a bridge rectifier element. The utility model is characterized in that the bridge rectifier element is additionally arranged between the electromagnetic coil and an alternating current power supply; the current which enters the electromagnetic coil is changed from the alternating current into the pulse direct current. The utility model overcomes the influence on the electromagnetism attracting force when the alternating current cross zero point, improves the attracting force of the electromagnet, effectively reduces the material consumption, and reduces the product cost.
Description
The utility model discloses a kind of disconnected type alternating electromagnet, belong to electric type.
For a long time, the alternating electromagnet that people use since when being subjected to zero-crossing of alternating current to the influence of electromagnetic attraction, electromagnetic attraction is not high.Therefore, often in magnetic circuit, adopt to install short-circuited conducting sleeve additional and to add high-power way and satisfy in the use requirement electromagnetic attraction.Small product size is big, the cost height, and often with tedious hum.
The purpose of this utility model, a kind of volume is little, in light weight, cost is low, noiseless novel alternating electromagnet for the user provides exactly, is described as follows in conjunction with the accompanying drawings with the needs that satisfy the user.
Accompanying drawing is novel alternating electromagnet structural representation.
That novel alternating current magnet is used in the used interchange of ac contactor device shown in the accompanying drawing An embodiment of electromagnet can also be traction electromagnet, braking electromagnet.
A kind of novel alternating electromagnet mainly is made up of iron core (1), solenoid (2), armature (3), bridge rectifier element (4), it is characterized in that: a bridge rectifier element (4) is electrically connected with it between solenoid (2) and AC power.
As shown in drawings, make two lead-out wires of the solenoid (2) in the novel alternating electromagnet, be connected on respectively on (5) and (6) point of bridge rectifier element (4), and with two ends, the left and right sides (7), (8) of bridge rectifier element (4), respectively as the terminal that is connected with AC power.
Because the characteristic of alternating current, the suction of former alternating electromagnet fluctuates thereupon.During peak value, the suction maximum, during zero crossing, suction is similar to zero.Therefore we can say that the suction of this electromagnet is a mean value similar to alternating current, efficient is therefore lower.
When (7) of novel alternating electromagnet, when (8) insert an AC power, through bridge rectifier element (4) rectification, make the electric current that enters solenoid (2) become Rectified alternating current by alternating current, changed the phenomenon of former zero-crossing of alternating current, the suction that has overcome former alternating electromagnet with the fluctuation of alternating current fluctuate, electromagnetic attraction is similar to zero drawback when the continuous conversion of polarity of the magnetic field, zero crossing.The electromagnetic attraction that acts on the armature (3) is improved greatly, realized the purpose of the utility model.After the enforcement, will bring many benefits for the user.Simultaneously, also can save great deal of steel and copper material for country.
