Description

Energy saving dc connector

The utility model belongs to a kind of energy saving ac contactor that plays automatic control action in the electric automatic control link.

Existing general A.C. contactor all is to produce a certain amount of magnetic flux by hot-wire coil, in ferrosilicon core up and down, produce magnetic force attract each other in conjunction with and keep operating state.The reactive power loss that the coil power loss of this contactor and coil attach is all bigger.With the contact electric current of make-and-break is 10 amperes contactor, and its consumed power is about 10 watts.Because having many uses of A.C. contactor, nearly all electrical equipment all can not lack, thereby the energy value that is consumed is very surprising.Therefore, reduce the reactive loss of A.C. contactor, improve the energy-saving effect of A.C. contactor, become countries in the world and pay much attention to, conscientiously Yan Tao problem.

The purpose of this utility model is that a kind of function of design is the same with existing contactor at the defective of existing A.C. contactor, but structure is more reasonable, and hardware cost is lower, the energy saving ac contactor of good energy-conserving effect.

The method that the utility model is finished is that the magnetic action of permanent magnet is introduced in the course of work of A.C. contactor, utilizes the magnetic force that produces and non-consumes energy reaches energy-conservation purpose.

Advantage of the present utility model: simple and reasonable, stable and reliable working performance, easy to install; Utilize portion's line magnetic force of the magnetic force replacement coil generation of permanent magnet cleverly, its power consumption has only between the 25-50% of existing A.C. contactor; Fractional energy savings can be controlled between the 50-75%, and good energy-conserving effect is promoted easily to substitute existing A.C. contactor, and product cost is low, can bring into play good economic benefits and social benefit.

Accompanying drawing 1 is an agent structure schematic diagram of the present utility model, and Fig. 2 is electric control theory figure, and Fig. 3 is the electromagnet coil structure principle chart.

Most preferred embodiment of the present utility model: piece under the ferrosilicon core (5) is installed on the rubber bar (9) of base (10) bottom, permanent magnet (12) is installed on the rubber gasket (11) of base (10) bottom, and piece (4) is positioned at top, and the contact pedestal (1) of base adapted of base on upper end and the ferrosilicon core that actuating mechanism (2) is connected.Back-moving spring (3) lower end of piece is installed on the electromagnet coil (6) on the supporting ferrosilicon core, and electromagnet coil is installed under the ferrosilicon core on the rubber gasket in the piece (7), and magnetite attracts guide card (8) upper end to be fixed on the ferrosilicon core on the piece.When this A.C. contactor is switched on, electromagnet actuating coil (14) energising, between the ferrosilicon core, produce magnetic force, when the tension force that piece overcomes back-moving spring on the ferrosilicon core moves downward and engages with piece under the ferrosilicon core, the lower end that is fixed on the attraction of the magnetite on piece guide card on the ferrosilicon core is attracted by the permanent magnet of bottom, at this moment electromagnet actuating coil outage, electromagnet is kept coil (15) energising, keep the tension force of the magnetic force sum of magnetic force that coil produces and permanent magnet generation greater than back-moving spring, on, the firmly combination of following ferrosilicon pellet, this moment, this A.C. contactor was in running order.The power consumption of keeping coil has only the 25-50% of actuating coil.When keeping coil blackout, the magnetic force that the tension force of its back-moving spring produces greater than permanent magnet, piece resets rapidly on the ferrosilicon core, and the A.C. contactor of this moment is in release condition, finishes a work period.And, the production of the utility model practical electromagnet.

Claims (2)

1, a kind of energy saving ac contactor, comprise the ferrosilicon pellet, electromagnet coil, it is characterized in that piece under the ferrosilicon core (5) is installed in base (10) bottom, permanent magnet (12) is installed in the bottom of base, piece (4) is positioned at top, and the contact pedestal (1) of base adapted of base on upper end and the ferrosilicon core that actuating mechanism (2) is connected, back-moving spring (3) lower end of piece is installed on the electromagnet coil (6) on the supporting ferrosilicon core, electromagnet coil is installed under the ferrosilicon core in the piece, and magnetite attracts guide card (8) upper end to be fixed on the ferrosilicon core on the piece.

2, contactor according to claim 1 is characterized in that electromagnet coil is by actuating coil (14) with keep coil (15) and form.
