Description
Technical field
The utility model relates to the electric equipment technical field, particularly a kind of little power consumption energy-saving contactor.
Background technology
The various interchanges of present industrial use, D.C. contactor all adopt electromagnet coil to continue energising generation electromagnetism adhesive and work.Its electromagnet coil power consumption meeting is along with the capacity of contactor increases and increases, report according to interrelated data, nationwide, the total power consumption of the various contactors that using are very surprising, and the annual economic loss that causes to country reaches hundred million yuans of 100-200.Simultaneously, existing contactor in use also can produce harmful noise and vibration.
Summary of the invention
The purpose of this utility model provides little power consumption energy-saving contactor of a kind of reliable operation, noiselessness, friction, DC-AC two-use.
The feature of described little power consumption energy-saving contactor is: contactor is provided with little power consumption electronic switch 1, mechanical type latch nook 2 and trip electromagnet 3.Described little power consumption electronic switch 1 is connected with power supply through contactor closing coil 5, contactor switch knob 4-2 and contactor trip button 4-1; Described mechanical type latch nook 2 is connected with contactor " E " sections core top movable; Described trip electromagnet 3 is fixedlyed connected with contactor " E " sections core top.
Its operation principle is such: after pressing contactor combined floodgate knob 4-2, closing coil 5 energisings, after inhaling the lock electromagnetic actuation, after blocking making electromagnet and form self-locking by mechanical type latch nook 2, closing coil 5 outages, it is extremely low that contactor adopts little power consumption electronic switch to wait for operating current in the operating supervision of work, (about 30 microamperes) its power consumption is only for having the 1/500-1/3000 of contactor now, when pressing trip button 4-1 or having a power failure, contactor discharges it, and to discharge electrocardio can be to finish by the stored electrical equipment of electronic switch capacitor 6 self.
Characteristics of the present utility model and beneficial effect are:
1, mechanical self-latching type is kept adhesive, thus noiselessness, friction.
2, identical with existing contactor function, the energising adhesive, outage or have a power failure to discharge, but different be, the release here is not to rely on the mains supply action, but finishes trip avoidance function by self energy storage capacitor.
3, owing to adopt little power consumption electronic switch control "on" and "off", no matter so size of contactor capacity, be in operation, consumed power all≤6mw, compare with existing contactor, power consumption is its 1/500-1/3000 only, and though be 380V or 220V supply current all less than 30 microamperes, the energy-saving effect highly significant.
4, safe and reliable, in use, as this contactor of an initiating signal (pressing starting button) refusal work of not bothering to see me out.
5, behind grid power blackout, close as drawing by force artificially, forget that again tripping resets after, as long as one the incoming call, this contactor tripping automatically resets.
6,60A above contactor, trip electromagnet can be set separately; What 60A was following just is not provided with trip electromagnet, that is: the adhesive electromagnet is again a trip electromagnet, is the control method difference of self-locking card, and the circuit of electronic switch is also slightly different.
The utility model has also simultaneously that cost is low, reliable operation, work noiselessness, friction, extremely low, the Remarkable Energy Saving advantage of power consumption, is adapted to all industrial electrical equipments control fields.
