Abstract
The utility model relates to an energy-saving contactor which is composed of a magnetic core and a control circuit. The utility model is characterized in that the magnetic core is an integral E-shaped hard magnet block, and the control circuit is composed of a rectification circuit, a clamp circuit and a demagnetizing circuit. The energy-saving contactor has the advantages of simple structure, no noise and energy saving; compared with conventional and traditional contactors with the same capacitance, the utility model can save energy by 90%.
Description
The utility model relates to a kind of contactor, belongs to essential electronic element.
Industrial automation control centre extensively adopts the break-make of contactor control main circuit or big capacity circuit at present, these contactors are all by a solenoid, one pair of closed assembly soft magnetic core, form with dynamic and static contact, its operation principle is by producing magnetic field to coil power supply, magnetic core Attraction strap moving contact being switched on or switched off.The shortcoming of this structure is coil energising work for a long time, could keep the magnetic core adhesive.Coil is switched on for a long time, can continue consumed power, and not only power consumption is big, and can cause coil heating, influences useful life.
The purpose of this utility model is to provide a kind of power consumption little for addressing the aforementioned drawbacks, the contactor of long service life.
The technical solution of the utility model is to change existing soft magnetism closed assembly magnetic core into whole Hard Magnetic core, utilizes hard magnetic material energy storage, maintenance, stable magnetic characteristics, by the forward power supply or the energy storage capacitor C of interlock circuit butt joint lashing ring
3Back discharge, magnetic core is magnetized or demagnetize, reach the purpose of control contact, this kind contactor is once magnetizing, the magnetic core saturation magnetization, charging current is ended rapidly, and the time of magnetizing, magnetic core kept adhesive less than 1 second, coil needn't have electric current again, this moment, entire circuit was in hold mode, and power consumption than the little 10-35 of traditional product doubly relies on energy storage capacitor C in the interlock circuit when circuit disconnects
3Discharge, and under the effect of back-moving spring, drive contact and reset, Hard Magnetic can not produce eddy current, so magnetic core needn't be made by closed assembly, has reduced the complexity of manufacturing.
Below in conjunction with accompanying drawing the utility model is described in detail.
Accompanying drawing 1 is a Hard Magnetic cored structure schematic diagram of the present utility model;
Accompanying drawing 2 is the circuit diagram of the utility model control magnetic core motion.
Quiet, moving magnetic core (1) (2) of the present utility model all is whole E font Hard Magnetic piece, dynamic and static magnetic core is connected by tie point (3) (4) and control circuit, when power on circuitry, circuit is powered to contactor coil (L), magnetostatic core (1) is magnetized, and moving magnetic core (2) is attracted two magnetic core adhesives, and relying on Hard Magnetic magnetic energy that core stores up to keep adhesive, coil is consumed power not; When down circuitry, capacitor C
