Description
Technical field
The present invention relates to a kind of mechanical type self-locking catalyst and method of work thereof.
Background technology
In electrical apparatus controlling system, catalyst and relay are the low-voltage electrical apparatuses being widely used, and wherein A.C. contactor is most frequently used.A.C. contactor is mainly used in the electric wiring to bigger load current load and realizes connecting and disjunction control.Existing catalyst is mainly made up of parts such as electric magnet (magnet exciting coil, iron core), contact mechanism (normally opened contact, normally-closed contact, pull bar), arc-control device, back-moving spring and armature.After the magnet exciting coil of catalyst is energized, electric magnet just produces electromagnetism (suction) power.The counteracting force overcoming back-moving spring is made its armature adhesive by this electromagnetic force, band dynamic contact mechanism action and make its normally opened contact Guan Bi and normally-closed contact disconnect, it is achieved the switching of circuit controls.Keep this state, it is necessary to power persistently to the electric magnet of catalyst.When electric magnet dead electricity, electromagnetic force makes its armature discharge much smaller than the opposition of back-moving spring, then the normally opened contact of catalyst and normally-closed contact all reset, the original state of restoring circuit.All kinds of catalysts are similar in structure and principle, and maximum difference is the difference of rated operational current and power thereof, make catalyst have very big difference on volume.
For the on off control of large power-consuming equipment, A.C. contactor requires that contact mechanism has larger space, to allow to flow through bigger rated current；Also persistently to maintain the adhesive of its armature to electric magnet energising, circuit just can be made to keep duty.Owing to the job demand power supply of catalyst maintains, then cause electric energy continued depletion, the serious waste energy, and the problems such as the magnet exciting coil heating of ubiquity electric magnet, then accelerate the insulation ag(e)ing of magnet exciting coil, reduce service life.For A.C. contactor, the power himself consumed is about 30～300W, and China has the A.C. contactor of more than several hundred million using at present.Visible, catalyst (particularly A.C. contactor) is genuine electricity-eating tiger.In order to solve these problems, people have studied for a long period of time, and achieve some achievements.
China Patent Publication No. CN2388703 saving device for alternating current contactor, it is to adopt DC circuit magnetic loop to lock the contact closure condition of A.C. contactor, reaches energy-conservation purpose；Its shortcoming is that DC circuit magnetic loop can produce remanent magnetism, will be likely to occur its moving armature when power is off and static gag bit cannot separate, and reduce the reliability of A.C. contactor switching, even cannot normal operation.
