Abstract
The utility model discloses a micro-power consumption and no-noise AC contactor, mainly comprises an electromagnetic system, a movable contact support frame, a retaining spring, a positioning groove, a compression reed, a movable contact, a static contact, etc. The contactor uses action of the retaining spring and the positioning groove, so that the electromagnetic system is powered on once in a moment, and the contactor is on an on-state. Then the electromagnetic system is powered on again, and the contactor is on an off-state. Thus, the contactor eliminates disadvantages that an electromagnetic system of a previous contactor inevitably consumes power when working with an electric appliance, thereby effectively saving electric energy. The contactor is on a mute state when working, so noise pollution is effectively reduced. Using the contactor has positive meaning for saving energy and reducing noise pollution.
Description
Technical field
The utility model relates to control apparatus commonly used in the industrial production, is specifically related to a kind of little power consumption, zero noise A.C. contactor, belongs to the contactor field.
Background technology
The kind of contactor is a lot, and A.C. contactor, D.C. contactor, permanent magnet contactor, relay etc. are arranged, and is mainly used in remote frequent the connection and minute deenergizing or control system.Especially A.C. contactor, consumption is maximum in control apparatus.This contactor spurs many windings point with an electromagnet.During electromagnetic actuation, junction closure, electrical appliance work.Otherwise, the electromagnet dead electricity, electrical appliance quits work.That is to say that [when doing, electromagnet also must be in uses electricity condition when electrical appliance needs two.
As everyone knows, the effect of electromagnet in contactor only is the pulling junction closure, other action: discharge such as contact, electrical appliance quits work etc., does not need electromagnet to go to finish.Electromagnet keeps using electricity condition for a long time with the work of electrical appliance, be a kind of meaningless loss fully, has so just caused the power consumption of electromagnet, 99% all be used in the meaningless loss, greatly wasted the energy, and its noise that produces under the sticking state is larger, two have 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 some mainstream products occurred:
Phase I: 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 the 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 to increase the device of the energy-saving coil of power saving apparatus or transformer and so on newly and the electromagnetic system of A.C. contactor self combines together, reduced the cost of newly-increased power saving apparatus.
Set up outside more than newly-increased economize on electricity series products is and execute, not only increased a new cover in the outside of contactor ' affiliated facility, increased product cost, the auxiliary economize on electricity point that has also taken contactor that has, introduced electronic circuit, increased the complexity of product, and effect is general aspect economize on electricity, reduction noise.
Summary of the invention
The utility model is exactly a kind of little power consumption, the zero noise A.C. contactor that provides for problems such as the meaningless loss that overcomes contactor are too large, noise pollution is serious, it can make only electricity consumption when starting and disconnect of contactor, not electricity consumption under the sticking state, thereby the purpose of realization economize on electricity.
The technical scheme that its technical problem that solves the utility model adopts is: in the bottom of contactor case, E font iron core is installed successively, helical electromagnetic coils, the middle part is equipped with E font armature, the intermediate projections part of iron core and armature, be enclosed within respectively in the helical electromagnetic coils, upside at armature, be connected with the moving contact bracing frame, movable contact is placed in the top of movable contact bracing frame, on the corresponding shell position of movable contact, break is installed, on the top of movable contact bracing frame, be provided with positioning groove, on the corresponding shell position of positioning groove, retainer spring is installed, compress reed, between the upper end of the lower end of movable contact bracing frame and helical electromagnetic coils, back-moving spring is installed, and solenoid is electrically connected with outside by binding post.
Iron core, solenoid, armature, movable contact bracing frame, retainer spring, movable contact, break, back-moving spring etc., all are original members of A.C. contactor, there are electricity, electroless state to control the closure of movable contact, break, off-state by the control solenoid, come the work of control overhead or stop with this.
Former A.C. contactor is by keep load operation to the mode of solenoid power supply always.The utility model is to move up and down, make it and be placed on closure, the off-state that retainer spring in its groove is subjected to displacement to control movable contact, break by what be arranged on positioning groove on the movable contact bracing frame, and comes the work of control overhead or stop with this.That is to say, the utility model is on the basis that does not change former A.C. contactor structure, interaction by mechanical components such as newly-increased positioning groove, retainer springs, just can realize the electromagnetic system energising once, contactor enters on-state, electromagnetic system is switched on once again, and contactor just can enter off-state.That is to say, no matter how long load needs work, electromagnetic system only needs twice of moment energising, all the other times are off-position, so thoroughly eradicated electromagnetic system also drawback of power consumption in vain when load operation, its power savings is fairly obvious, and electromagnetic system is off-position when contactor is worked, so its noise is zero.
