Abstract

A silent power saver used in combination with an AC contactor.
The power saver can reduce the energy consumption of the alternating current contactor, eliminate noise, occupy no auxiliary contact of the alternating current contactor and be convenient to install. The electronic circuit consists of capacitor step-down circuit, diode rectifier circuit, follow current circuit and SCR delay cut-off circuit, all the electronic elements are sealed in the casing, and only three leading-out wires are set outside the casing and connected to the AC contactor and two ends of power supply separately, or the casing may be set inside the AC contactor to form one new type of contactor.

Description

Power economizer
The utility model relates to a kind of A.C. contactor operating condition that is used to change, the silent running electricity-saving appliance of being made up of electronic component.
Present widely used cJ 10, cJ 12When the ac operation, the energy consumption that short-circuited conducting sleeve produces in energy consumption that is produced in iron core by magnetic hysteresis and eddy current and the magnet accounts for 91% of total energy consumption etc. Series AC Contactor, and the energy consumption of sucking coil accounts for 9%, produces AC noise simultaneously.
In order to reduce above-mentioned energy consumption and to eliminate noise, under the prerequisite that does not change the member of former A.C. contactor own, used known various ac contactor silent operation battery saving arrangement at present.These battery saving arrangements utilize at least one pair of above auxiliary contact of A.C. contactor itself or associated contact, to realize the conversion of A.C. contactor starting with operation.The cJJ series electricity-saving appliance, the WJ that for example show domestic use 2Products such as series electricity-saving appliance, XD-3 quiet electricity economizer.
But, utilize the auxiliary contact of A.C. contactor own after, changed the original wiring of A.C. contactor, make the wiring complexity.Aspect reliability, auxiliary contact are had relatively high expectations, contact bad slightly or cooperate on the time and be taken in, just may damage electricity-saving appliance, make it cisco unity malfunction.
In addition, existing electricity-saving appliance all seems, and volume is bigger, only is applicable to the A.C. contactor that 100A is above.More than these defectives, limited promoting the use of of these electricity-saving appliances.
The purpose of this utility model is achieved in that in a shell, a circuit board with epoxy encapsulation, externally draws three and thoroughly does away with the edge lead.Wherein two are connected with the ac contactor coil two ends, and another root is connected with power supply.When press push button QA, A, the B two ends promptly add 380V or 220V AC power, electric current is through D 3, R 1D 4Add to controllable silicon T 1The G utmost point, controllable silicon is triggering and conducting thereupon, A.C. contactor JC gets electric adhesive, simultaneously capacitor C 2C is worked as in charging 2When voltage reaches certain value, triode BG conducting, controllable silicon T 1The G pole tension descend thereupon, until controllable silicon T 1End, at this moment by capacitor C 1Step-down and for A.C. contactor JC provides holding current, diode D 1, D 2For A.C. contactor JC provides the afterflow path, make A.C. contactor JC be in DC low-voltage, little electric current hold mode.Realized the automatic conversion of A.C. contactor starting, reached the purpose that makes the operation of A.C. contactor energy-saving silencing with operating condition.
The utility model and A.C. contactor are external, because of volume is little, and the A.C. contactor inner space of also can packing into, still wiring routinely of A.C. contactor during use.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is circuit theory diagrams of the present utility model.In the drawings, D 1Fly-wheel diode, D 2Rectifier diode, D 3Rectifier diode, D 4Diac, T 1Controllable silicon, BG triode, R 1Resistor, R 2Resistor, R 3Resistor, R 4Resistor, C 1Capacitor, C 2Electrolytic capacitor, 1 lead-out wire, 2 lead-out wires, 3 lead-out wires, JC ac contactor coil, JC 1A.C. contactor auxiliary contact, TA cut-off push button, QA push button, a-power supply end, B-source end.
Among the figure, be the electricity-saving appliance internal circuit in the frame of broken lines, each electronic component of electricity-saving appliance connects according to circuit diagram in the frame of broken lines among the figure.Empty frame is outward the A.C. contactor external control circuit.
