Technical field
The utility model relates to a kind of A.C. contactor, particularly a kind of intelligent AC contactor.
Background technology
A.C. contactor mainly is made up of electromagnetic system, contact system, arc quenching system and other part.1. electromagnetic system: electromagnetic system comprises solenoid and iron core, is the important component part of contactor, relies on its to drive the closure and the disconnection of contact; 2. contact system: the contact is the operating part of contactor, comprises main contacts and auxiliary contact.The effect of main contacts is to connect and the disjunction major loop, control bigger electric current, and auxiliary contact is in control loop, to satisfy the requirement of various control modes.3. arc quenching system: when arc-control device was used for guaranteeing the contact open circuit, the electric arc of generation extinguished reliably, reduced the damage of electric arc to the contact.4. other parts: insulation crust, spring, short-circuited conducting sleeve, transmission mechanism etc. are arranged.
A.C. contactor is when coil electricity, and static iron core produces electromagnetic attraction, will move the iron core adhesive, because contact system links with moving iron core, therefore moving iron core drives three movable contact springs and moves the closing of contact, thereby energized simultaneously.When coil blackout, suction disappears, and moving iron core interlock part relies on the reaction force of spring and separates, and main contact is disconnected, and cuts off the electricity supply.
A.C. contactor is the most basic control apparatus, is widely used in low-voltage distribution and automation field, and it is easy to use, and is cheap, safeguards simple.But it can not carry out running status indication and man-machine interaction, and its electromagnetism actuating mechanism has brought operation that noise, energy consumption is big, failure rate is high, useful life is low problem are arranged, and easily causes to produce and interrupts, even product rejection, has a strong impact on industrially to carry out smoothly.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of intelligent AC contactor, can indicate running status and realize man-machine interaction, fundamentally eliminate running noises, realize silent running, cut down the consumption of energy greatly, improve service life; On the other hand, can realize the online detection of each operational factor, carry out fault pre-diagnosing and real-time diagnosis,, reduce influence as far as possible producing so that product rejection is avoided in preventive maintenance and maintenance in time.This product has compact conformation, highly versatile, characteristics with low cost simultaneously.
To achieve these goals, the technical solution adopted in the utility model is: a kind of intelligent AC contactor, include power supply 10, power supply 10 links to each other with the power end of control unit 1, control unit 1 is provided with processor MCU 2, the input of processor MCU 2 links to each other with the output of amplifier 3, the input of amplifier 3 links to each other with the output of transducer 4, the AD end of processor MCU 2 connects filtering, the input of reshaper 5, filtering, the input of reshaper 5 links to each other with the output of transducer 6, the input P1 mouth of processor MCU 2 links to each other with the output of input unit 7, the output of processor MCU 2 is connected with alarm unit 8, and the P3 end of processor MCU 2 is connected with display unit 9, and the P3 mouth of the control end of rectification module 11 and MCU2 links to each other, AC power becomes direct current after by rectification module 11, is added on the contactor line bag 12.
The utlity model has following advantage: owing to adopted microprocessor, system can realize man-machine interaction, key parameter in the time of can detecting the A.C. contactor operation automatically, the while can show the parameter of needs, and carries out fault pre-diagnosing and fault real-time diagnosis according to these parameters.System changes the control method of conventional AC contactor, adopts the direct current scheme to control, and has fundamentally eliminated running noises and vibration, greatly reduces energy consumption, has improved useful life.Has compact conformation, with low cost, original relatively A.C. contactor, the characteristics that cost is low.
