Abstract
The invention relates to an energy-saving control module for a residual-magnetic contactor. Relays and contactors, which are hereinafter referred to as contactors, have many kinds of energy-saving operating schemes, and the most energy-saving operating scheme is a magnetic latching contactor, because coil current of the magnetic latching contactor under a latching state is zero. Magnetic latching is divided into a permanent magnetic mode and a residual magnetic mode. A permanent-magnetic magnetic latching contactor is internally provided a permanent magnet with fixed polarity, the polarity of voltage applied to a coil is paid attention to in the using process so as to avoid a mistake, if not, a trouble is brought about in use. In addition, an electromagnetic system of the permanent-magnetic magnetic latching contactor must be redesigned; and a residual-magnetic contactor does not need a permanent magnet, and an iron core structure can maintain the status quo, thereby being convenient for carrying out transformation on an existing contactor, and being particularly applicable to transformation of high-capacity contactors with the capacity being above 250A. The energy-saving control module provides a convenient way for solving such problems.
Description
Art: low-voltage electrical apparatus
Background technology: relay, the energy-saving run scheme of catalyst [hereinafter referred to as catalyst] have many kinds, the most energy-conservation no more than magnetic latching contactor, because its coil current is zero in the hold state.Magnetic keeps dividing again magneto and two kinds of forms of residual magnetism type.There is the permanent magnet of a fixed polarity inside magneto magnetic latching contactor, therefore in use it should be noted that the polarity of voltage being added on coil, must not get wrong, otherwise can make troubles to use.And the electromagnetic system of magneto magnetic latching contactor must be from new design；Residual magnetism type contactor can maintain the original state without permanent magnet, core construction, it is simple to transforms existing catalyst, is particularly suited for the transformation of more than 250A Large Copacity catalyst.The present invention is exactly for solving problems offer one approach easily.
Summary of the invention: by a part for the magnetic system of former catalyst, change the retentive material with one fixed width hysteresis curve into, former catalyst has just been transformed into the magnetic system of a residual magnetism type contactor, coordinate special energy-saving control module to be driven again, just constitute a complete energy-conservation remanent magnetism catalyst.The present invention focuses on special energy-saving control module.
Technical scheme: on remanent magnetism contactor coil within energising 100 milliseconds, its coil is filled with strong dc electricity, catalyst adhesive.Owing to containing hard magnetic material in magnetic system, therefore suction produced by its remanent magnetism be enough to make catalyst keep attracting state, it is no longer necessary to additional holding electric current.It should be noted that remanent magnetism catalyst not mind initially and be added in the polarity on coil, reason is that " remanent magnetism ".When circuit power-off or the low numerical value to regulation of voltage, energy-saving control module be just given one with the contrary release voltage of voltage direction applied during adhesive, catalyst release.
Application prospect: the hard magnetic material cost that remanent magnetism Contactor Magnetic System uses is less than silicon steel sheet, and coil copper is fewer than former catalyst, and coil current is zero the most in the hold state, and these three indexs are superior to existing catalyst.Therefore the present invention has certain application prospect.
Accompanying drawing illustrates:
Fig. 1 is the electrical schematic diagram of remanent magnetism catalyst energy-saving control module；
1, after connecing electricity, 220V alternating current DC voltage after C3 blood pressure lowering, BR1 rectification is added on the coil of J1, J1 adhesive.
2, after J1 adhesive, the normally opened point of its J1-2 is that C1 provides charge circuit.Charge circuit includes D1, C1, J2 coil SRS, R3.Owing to charge circuit includes the coil SRS of J2, so J2 is adhesive in charging process, J2 pickup time about 100MS.
3, D3, D4, SCR1, SCR2 constitute full-bridge provides DC high-voltage for contactor coil.When J2 adhesive, SCR1, SCR2 triggering and conducting.Contactor coil JCQ powers up, catalyst adhesive.The normally opened point of J1-1 and D6 complete afterflow, to eliminate electric spark.
4, when cut off the electricity supply or supply voltage low to setting time J1 release.C1 is discharged by the normally closed point of J1-1, the normally closed point of contactor coil JCQ, J1-2, D5, and catalyst discharges.It should be noted that the discharge current direction of JCQ is on the contrary with its operating current direction.
5, ZD1, C2, R2 and C4, R4 are used for regulating time parameter and action parameter.
