Abstract
The utility model discloses a micro-power-consumption zero-noise contactor capable of power failure protection. The contactor is mainly composed of an electromagnet, a movable contact support, a positioning groove, a movable contact, a static contact and a power failure protection system. Due to mutual interaction between a control pin and the positioning groove, an electromagnetic coil is instantaneously electrified for one time to connect the contactor, and the electromagnetic coil is electrified again to disconnect the contactor. Thus, it is effectively avoided the disadvantage that in the prior art, the electromagnetic coil of the contactor inevitably consumes electricity when the electromagnetic coil works together with an electric appliance, so that electric energy can be effectively saved. The contactor works in a noiseless state, thereby effectively reducing noise pollution. Use of the micro-power-consumption zero-noise contactor capable of power failure protection has significance in saving energy and reducing noise pollution.
Description
Technical field
The utility model relates to the conventional control apparatus class in industrial production, is specifically related to a kind of micro-power consumption with loss protecting function, zero noise contactor, belongs to Low Voltage Electrical Apparatus.
Background technology
The kind of contactor is a lot, has A.C. contactor, D.C. contactor, permanent magnet contactor, relay etc., is mainly used in remote frequent connection and minute deenergizing or control system.Especially A.C. contactor, in control apparatus, consumption is maximum.This contactor, pulls many group contacts with an electromagnet.During electromagnetic actuation, junction closure, electrical appliance work.Otherwise, electromagnet dead electricity, electrical appliance quits work.That is to say, when electrical appliance need to be worked, electromagnet is also inevitable in power consumption state.
As everyone knows, the effect of electromagnet in contactor is only to pull junction closure, other action: as contact discharges, electrical appliance quits work etc., does not need electromagnet to go.Electromagnet keeps "on" position for a long time with the work of electrical appliance, a kind of meaningless loss completely, this has just caused the power consumption of electromagnet, more than 99% electric energy all consumes in this meaningless loss, greatly wasted the energy, and it is for a long time under sticking state, and solenoid easily burns.And its noise producing is larger, has directly polluted environment.
For above-mentioned drawback, domestic and international many experts, scholar have carried out a large amount of research, improvement to this, especially, aspect power-saving technique, have experienced three developing stage, and have occurred some mainstream products:
First stage: representative products is economizer of AC. contactor.It has capacitor-type, transformer type and change duty ratio from three kinds of change types.
Second stage: representative products is contactor power saving coil.It has double winding energy-saving coil formula, current-limiting resistance formula energy-saving coil, double winding self-transfer electricity-saving coil and orientation magnetic comersion economizer coil etc.
Phase III: electricity-saving type A.C. contactor.Be that the device of the energy-saving coil of newly-increased power saving apparatus or transformer and so on and the electromagnetic system of A.C. contactor self are combined together, reduced the cost of newly-increased power saving apparatus.
More than newly-increased economize on electricity series products is set up and is executed outside being, and not only in contactor outside, has increased a set of new affiliated facility, has increased product cost, and the auxiliary contact that has also taken contactor having makes troubles to the use of field control circuit.What have has also introduced electronic circuit, has increased the complexity of product, and general in economize on electricity, the effect that reduces aspect noise.
Recently a kind of permanent magnetism type contactor occurring, although there is obvious advantage aspect economize on electricity, it has, and antijamming capability is low, Reliability of Microprocessor is subject to that ectocine is large, poor stability, the many drawbacks of high in cost of production, therefore can't be widely accepted on market.
Summary of the invention
The utility model is exactly the problems such as meaningless loss in order to overcome contactor is too large, noise pollution is serious and a kind of micro-power consumption with loss protecting function, the zero noise contactor that provide.It can make only electricity consumption when starting and disconnect of contactor, and not electricity consumption under sticking state, and while having a power failure suddenly at the scene, can make contactor be automatically converted to off-state, thereby both realize the object of economize on electricity can make again contactor cause safety under nonserviceabling.
The technical solution adopted for the present invention to solve the technical problems is: in the bottom of contactor case, iron core is installed successively, solenoid, middle part is provided with armature, bossing in the middle of it, through armature back-moving spring, intermediate projections part with iron core, be enclosed within respectively in solenoid, the upside of armature, by connector, be connected with movable contact bracing frame, movable contact is placed in the slot on movable contact bracing frame top, on the corresponding shell position of movable contact, break is installed, right side at movable contact bracing frame, be provided with positioning groove, right side, upper end at shell corresponding to positioning groove, loss protecting electromagnet base is installed, thereon, be separately installed with and control pin, control pin back-moving spring, control pin and compress reed, loss protecting solenoid, loss protecting armature, extension spring, loss protecting mechanism outer cover, loss protecting solenoid is electrically connected to outside respectively with solenoid.
Iron core, solenoid, armature, movable contact bracing frame, retainer spring, movable contact, break, back-moving spring etc., all original members of A.C. contactor, by controlling solenoid, there are electricity, electroless state to control the closure of movable contact, break, off-state, with this, control the work of electrical appliance or stop.
Former A.C. contactor be by solenoid power supply, make its always the mode in sticking state maintain electrical appliance work.The present invention be by be arranged on movable contact bracing frame right side positioning groove move up and down, make it and be placed on closure that control pin in electromagnet base lower horizontal hole is subjected to displacement to control movable contact, break, off-state, and control the work of electrical appliance or stop with this.That is to say; the present invention is not changing on the basis of former A.C. contactor structure; the interaction of selling members such as compressing reed, loss protecting electromagnetic system by newly-increased positioning groove, control pin, control pin back-moving spring, control; just can realize solenoid and electromagnetic system energising once; contactor just enters on-state; solenoid and electromagnetic system are switched on once again, and contactor just can enter off-state.That is to say, no matter how long electrical appliance needs work, solenoid only needs twice of moment energising, can realize its function needs, all the other times are off-position, have so thoroughly eradicated contactor also drawback of power consumption in vain when electrical appliance is worked, its power savings is fairly obvious, and solenoid is off-position when contactor is worked, and will become its useful life forever, and to make its noise be zero.
