Abstract
The utility model discloses a sound adsorbing and energy saving winding for a contactor, which is composed of a DC winding, an electricity saver, a travel switch, etc. An AC from an electric network can be rectified into a DC by the electricity saver which is composed of a full wave rectifier and a voltage reduction capacitor to supply the DC for a DC winding, and the AC operation mode of the contactor can be changed into a DC operation mode. The DC of full wave rectification can be supplied for a current winding via a starting circuit, and the DC of voltage reducing rectification can be supplied for a DC winding via a maintaining circuit. The utility model has a good electricity saving effect, and the apparent power and inactivity of the utility model can be greatly cut down. The application of the contactor of the utility model is more reliable, the heat generation, the vibration and the noise of the utility model can be reduced, the service life of the utility model can be correspondingly prolonged, and the cost of the utility model can be reduced.
Description
The utility model relates to the sound-deadening electricity-saving contactor coil that a kind of low-voltage electrical apparatus is used.
Existing A.C. contactor, its sucking coil passes to alternating current, it can directly obtain electric energy from electrical network, except that this is convenient be, the contactor heating of using AC coil is severe, and vibration and noise are also considerably serious, bring the excessive wear of the premature aging of insulation and iron core, armature pole-face thus, AC coil is under the alternating electromagnetism field action besides, and each turn-to-turn produces the active force of pulse type, causes the damage of coil easily.
The purpose of this utility model is to overcome the weak point of AC coil, thereby a kind of contactor coil of sound-deadening electricity-saving is provided.
Technical solution of the present utility model is, a kind of sound-deadening electricity-saving contactor coil, and it is by the direct current winding, and compositions such as electricity-saving appliance and travel switch, electricity-saving appliance comprise full-wave rectifier and decompression capacitor.The alternating current of electrical network is supplied with the direct current winding through the direct current of full-wave rectification.After treating the armature adhesive, the normally-closed contact of travel switch disconnects, and alternating current is through capacitance decompression and add to the direct current winding by rectifier and supply with and keep electric current, makes armature keep attracting state.
Below in conjunction with embodiment and accompanying drawing thereof, the utility model will be further described.
Fig. 1 is the partial cutaway front view of present embodiment.
Fig. 2 is the circuit diagram of present embodiment.
Present embodiment is made up of direct current winding (1), terminals (2), skeleton (3), travel switch (4) and electricity-saving appliance (5).Electricity-saving appliance (5) comprises full-wave rectifier and the decompression capacitor C that D1, D2, D3, D4 and D5, D6, D7, D8 two utmost point villous themedas constitute.K is the normally-closed contact of travel switch (4), and JC-1 is the normally opened contact of holding circuit.
After pressing QA1, start-up circuit is connected.Alternating current is supplied with direct current winding JC through the direct current of full-wave rectification, and under the effect of direct current winding JC, contactor armature is by the iron core adhesive.Armature after the adhesive promotes travel switch (4), and normally-closed contact K is disconnected, and normally opened contact JC-1 closure is so holding circuit is started working.Alternating current is through the capacitor C step-down and add to direct current winding JC by rectifier and supply with and to keep electric current, and holding armature is in attracting state, till QA2 presses.
The utlity model has obvious power savings, its apparent energy and reactive power are equal Greatly reduce. Use contactor of the present utility model, its heating, vibration and noise are all aobvious Work alleviates, and the work of contactor is more reliable, and service life is corresponding prolongation also.
Claims (4)
1, a kind of have a direct current winding, the sound-deadening electricity-saving contactor coil of electricity-saving appliance and travel switch, and the electricity-saving appliance (5) that it is characterized in that having full-wave rectifier and decompression capacitor is a direct current with AC rectification, supplies with direct current winding JC.
2, sound-deadening electricity-saving contactor coil according to claim 1 is characterized in that constituting start-up circuit and holding circuit respectively by the normally-closed contact K and the decompression capacitor C of travel switch (4).
3,, it is characterized in that the direct current of full-wave rectification is supplied with start-up circuit, and the direct current of step-down rectifier is supplied with holding circuit according to claim 1 and the described sound-deadening electricity-saving contactor coil of claim 2.
4, sound-deadening electricity-saving contactor coil according to claim 1 is characterized in that normally closed some K of travel switch (4) and decompression capacitor C are parallel in the circuit.
