Abstract
The invention provides an integrated forward and reverse rotation alternating-current contactor. The integrated forward and reverse rotation alternating-current contactor is characterized in that when a forward rotation starting button is pressed down, a forward rotation coil is powered on, electromagnetic attraction force is generated by a forward rotation static iron core, an armature is attracted down, a main forward rotation contact is closed, an auxiliary forward rotation normally-open contact is closed, and resistance of a contact spring is overcome by an auxiliary forward rotation normally-closed moving contact so that the auxiliary forward rotation normally-closed moving contact can be disconnected from an auxiliary forward rotation normally-closed fixed contact and a motor can be powered on to perform forward rotation; a reverse rotation starting button is pressed down, a reverse rotation coil is powered on, electromagnetic attraction force is generated by a reverse rotation static iron core, the armature is attracted up, a main reverse rotation contact is closed, an auxiliary reverse rotation normally-open contact is closed, and resistance of the contact spring is overcome by an auxiliary reverse rotation normally-closed moving contact so that the auxiliary reverse rotation normally-closed moving contact can be disconnected from an auxiliary reverse rotation normally-closed fixed contact and the motor can be powered on to perform reverse rotation. A stop button is pressed down, the armature returns, the motor is powered off to stop rotating, and the phenomenon that the contacts are burnt by arc light caused when the contacts make contact is avoided through an arc extinguishing chamber. Due to the arrangement, the number of the contactors in use is reduced, the motor is controlled to perform forward and reverse rotation, cost is saved, and maintenance is facilitated.
Description
The military border of the long political affairs of Liu flower Chen Wei
Technical field
The present invention relates to motor controller field, particularly a kind of rotating integral type A.C. contactor.
Background technology
In factory and people's life, utilize motor forward/backward rotation to realize the equipment of controlling innumerable, but the device of control motor forward/backward rotation normally two A.C. contactors is realized, not only to allow people see dazzled for numerous and diverse connection electric wire, and if there is trouble shoot, getting up is also hard brains.
Summary of the invention
The present invention proposes a kind of rotating integral type A.C. contactor, it is characterized in that: when pressing forward start button, forward coil electricity, forward fixed core produces electromagnetic attraction, inhale lower armature, forward main contact is closed, the auxiliary normally open contact of forward is closed, the auxiliary normally closed moving contact of forward overcomes the resistance of contact spring, disconnect with the auxiliary normally closed fixed contact of forward, motor obtains electric forward, press reversion start button, reversion coil electricity, reversion fixed core produces electromagnetic attraction, suct armature, reversion main contact is closed, the auxiliary normally open contact of reversion is closed, the auxiliary normally closed moving contact of reversion overcomes the resistance of contact spring, disconnect with the auxiliary normally closed fixed contact of reversion, motor obtains electric reversion.Press stop button, armature resets, the stall of motor dead electricity, and arc-extinguish chamber avoids contact to produce arc light, the contact of burning.
By above setting, the present invention reduces contactor and uses number, controls motor forward/backward rotation, saves cost, convenient maintenance.
Accompanying drawing explanation
Figure is schematic diagram of the present invention.
In figure 1, the auxiliary normally open contact 2 of main story, armature spring 3, forward fixed core 4, positive switch coil 5, forward main contact 6, the auxiliary normally closed moving contact 7 of forward, the auxiliary normally closed fixed contact 8 of forward, the auxiliary normally closed fixed contact 9 of reversion, the auxiliary normally closed moving contact 10 of reversion, reversion main contact 11, reversion coil 12, reversion fixed core 13, armature 14, the auxiliary normally open contact 15 of reversion, arc-extinguish chamber 16, contact spring A, auxiliary break contact partial enlarged drawing.
Embodiment
As shown in the figure: when pressing forward start button, positive switch coil 4 obtains electric and forward fixed core 3 generation electromagnetic attractions suction lower armature 13 forward main contact 5 closures, forward is assisted normally open contact 1 closure, resistance and the auxiliary normally closed fixed contact 7 of forward that the auxiliary normally closed moving contact 6 of forward overcomes contact spring 16 disconnect, and motor obtains electric forward.Press reversion start button, reversion coil 11 electric and reversion fixed core 12 produces electromagnetic attractions and sucts armature 13, reversion main contact 10 closures, auxiliary normally open contact 14 closures of reversion, the resistance that the auxiliary normally closed moving contact 9 of reversion overcomes contact spring 16 disconnects with the auxiliary normally closed fixed contact 8 of reversion, and motor obtains electric reversion.Press stop button, armature spring 2 makes armature 13 reset under reaction force, and each contact returns to normal, the stall of motor dead electricity.A is auxiliary break contact partial enlarged drawing.
Arc-extinguish chamber 15 avoids contact generation arc light to be burnt in contact.
