Description
(1) technical field
The utility model relates to a kind of electricity-saving appliance, especially relates to a kind of intelligent electricity-saving device of AC/DC contactor, belongs to the electrical equipment control technical field.
(2) background technology
At present, common contactor on the market generally adopts the mode of direct incoming transport electricity that it is powered.The contactor of this type of mode has the following disadvantages:
(1) lack in poor reliability, useful life: owing to adopt alternating current directly to power, suck when tending to cause contactor because of line voltage is unstable, time inhales pine and even do not inhale, so, can bring great arcing and damage to contacts of contactor, even can therefore strengthen and burn the probability of contactor line bag, thereby shorten the useful life of contactor greatly.
(2) energy consumption height: because contactor carries out adhesive by alternating current warp packet generation magnetic field, alternating current will produce induced current in the loop of closure, it is eddy current, heating will cause eddy current loss in the online bag of eddy current, not only expended electric energy greatly, and high temperature will reduce greatly the useful life of contactor line bag.
(3) noise is big: will produce drone hum when alternating current during by the line bag, form noise pollution.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can prolong contactor useful life greatly, reduces its energy consumption, reduces the intelligent electricity-saving device of AC/DC contactor of its noise.
The purpose of this utility model is achieved in that a kind of intelligent electricity-saving device of AC/DC contactor, include microprocessor, the AC/DC change-over circuit, the low-power consumption holding circuit, the height voltage conversion circuit, output circuit, switch switching circuit, buffer circuit one, voltage detecting circuit, buffer circuit two, power factor correction circuits and surge suppress electric source filter circuit, described alternating current inserts surge and suppresses electric source filter circuit, buffer circuit two and height voltage conversion circuit, described surge suppresses the output access power factor calibration circuit of electric source filter circuit, the output of described power factor correction circuits inserts the AC/DC change-over circuit, the output of described buffer circuit two links to each other with voltage detecting circuit, described AC/DC change-over circuit is respectively to microprocessor, the low-power consumption holding circuit, voltage detecting circuit and switch switching circuit power supply, described voltage detecting circuit links to each other with the input of microprocessor, the output of described microprocessor links to each other with display circuit with key circuit, the control end of described microprocessor links to each other with buffer circuit two, the output of described buffer circuit two links to each other with switch switching circuit with the height voltage conversion circuit, the output of described low-power consumption holding circuit and height voltage conversion circuit, the output of described height voltage conversion circuit inserts output circuit, and the output of described output circuit links to each other with switch switching circuit.
Workflow of the present utility model is:
(1) microprocessor will compare through the voltage of decompression testing circuit input and the magnitude of voltage in default and the microprocessor, when input voltage during greater than predeterminated voltage, microprocessor control height voltage conversion circuit output AC high voltage, open the switch switching circuit simultaneously, alternating current makes contactor be in attracting state;
(2) microprocessor control height voltage conversion circuit switches to the output LOW voltage DC mode after the adhesive of contactor line bag, will keep the attracting state of contactor line bag through the low-voltage DC input contactor line bag of low-power consumption holding circuit output;
(3) after the contactor adhesive, microprocessor compares input voltage and the drop away voltage value of presetting, and when input voltage was lower than drop away voltage, microprocessor was arranged at closed condition with switch switching circuit, made contactor thread off immediately; When input voltage is higher than drop away voltage, microprocessor compares input voltage and the rolling piezoelectric voltage value of presetting again, when finding that input voltage is lower than the rolling piezoelectric voltage, microprocessor picks up counting immediately, if input voltage is lower than default rolling piezoelectric voltage in the default timing period always, microprocessor is the off switch commutation circuit immediately, makes contactor thread off.
The beneficial effects of the utility model are:
(1) utilizes microprocessor that input voltage is controlled, guaranteed the stability of input voltage;
(2) only when starting, use alternating current that the line bag is magnetized, immediately change low-voltage DC over to and keep pattern, significantly reduced the generation of eddy current loss, reduced energy consumption, reduced the caloric value of contactor line bag, prolonged the useful life of contactor; Also stopped the generation of AC noise simultaneously.
