Abstract
A contactor with an electric energy saving device comprises an iron core, a coil, a contact and an electric energy saving device, is characterized in that the electric energy saving device is provided with a pulse width modulation control circuit. The utility model utilizes pulse width modulation control technology to ensure in the circuit start moment the executive power component of the circuit is in a saturated conductive status. High voltage and large current are input to the coil for the reliable attraction of the iron core. After a period of delay, the conductive angle of the executive power component becomes smaller. The lower voltage and small current is input to the coil to maintain the attraction of the iron core, thus the iron core can keep the attraction status reliably and the contactor runs normally. The utility model is provided with characteristics of electric energy saving and noise elimination.
Description
The utility model relates to the contactor in the low-voltage electrical apparatus field, refers in particular to a kind of contactor that has battery saving arrangement.
In the low-voltage electrical apparatus field, for problems such as the electromagnetic system power consumption that solves A.C. contactor are big, temperature rise, life-span are short, people design some electron type energy-saving damping running gears and reach for the electromagnetic type energy-saving and silencing apparatus, but adopt the contactor that has battery saving arrangement of transformer type or capacitor-type also to have some problems.Supporting always installation electromagnetic type of past, as the mechanical lock button, not only weak effect, and life-span is short, cost is high, is unfavorable for promoting.
The purpose of this utility model is to overcome the existing existing problem of contactor that has battery saving arrangement, and a kind of contactor that has battery saving arrangement is provided, and structurally battery saving arrangement and contactor are integrated for it, and effective, low cost of manufacture.
The solution that the utility model adopts is: a kind of contactor that has battery saving arrangement, comprise iron core, coil, contact, battery saving arrangement, and be characterized in that battery saving arrangement contains a control circuit for pulse-width modulation.
The utility model utilizes pulse width modulation controlled technique guarantee circuit starting moment, make the execution power device in the circuit be in the saturation conduction state, to coil input high voltage, big electric current, make the reliable adhesive of iron core, after time-delay a period of time, carry out the power device angle of flow and diminish, keep the iron core adhesive to coil input low-voltage, little electric current, iron core can be in reliably keeps attracting state, and contactor enters normal operating condition, the characteristics of have economize on electricity, eliminating the noise.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Fig. 1 is the electrical schematic diagram of the battery saving arrangement of present embodiment.
A kind of contactor that has battery saving arrangement, comprise iron core, coil J ↓, contact, battery saving arrangement, battery saving arrangement contains a control circuit for pulse-width modulation, as shown in Figure 1, in this control circuit for pulse-width modulation, power supply is by A ↓ 1, A ↓ 2 two ends input, through resistance R ↓ 1 step-down current limliting, again through diode D ↓ 2, capacitor C ↓ 1, resistance R ↓ 3, resistance R ↓ 4 are to capacitor C ↓ 2 chargings, resistance R ↓ 3 are connected across capacitor C ↓ 1 two ends, when the voltage on capacitor C ↓ 2 rise to diac Db ↓ conducting voltage after, trigger controllable silicon V ↓ full conducting, coil J ↓ have high voltage, big electric current, make the reliable adhesive of iron core, after one section time-delay, this delay time is by resistance R ↓ 1, R ↓ 4, capacitor C ↓ 1 decision, after capacitor C ↓ 1 charging finishes, change the angle of flow, make it with lower voltage, less current supply coil J ↓ enter the maintenance running status, during disjunction, capacitor C ↓ 1 is to resistance R ↓ 3 discharges, diac Db ↓ triggerless voltage, triggering controllable silicon V ↓ end, coil J ↓ dead electricity, this contactor is out of service.
As shown in Figure 1, also connect resistance R ↓ 2 between resistance R ↓ 1 and resistance R ↓ 4, this resistance R ↓ 2 determine sustaining voltage with resistance R ↓ 1, and decision just changes the angle of flow.
As shown in Figure 1, there is a diode D ↓ 1 negative electrode to meet power supply A ↓ 2 ends, anode connecting resistance R ↓ 1, resistance R ↓ 2, diode D ↓ 2 anodes.
As shown in Figure 1, have the negative electrode of diode D ↓ 3 connect power supply A ↓ 1 end, coil J ↓, the anode contact send out a controllable silicon V ↓ anode, coil J ↓ the other end.
As shown in Figure 1, have resistance R ↓ 5 connect the contact of power supply A ↓ 2 ends, the other end send out a diode Db ↓, trigger controllable silicon V ↓ control utmost point.
