Description of drawings
Fig. 1 is the electromagnetic system structure schematic diagram of present embodiment;
Fig. 2 is the electrical schematic diagram of the electronic element assembly of present embodiment.
Among Fig. 1: 1, coil; 2, conversion equipment; 3, decompression capacitor, 1-a, skeleton, 1-b, skeleton.
Embodiment:
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1, a kind of energy-saving contactor with conversion equipment, comprise shell, iron core, contact, auxiliary contact, arc-extinguish chamber, coil 1, electronic element assembly, coil 1 is made up of two skeleton 1-a, 1-b, one conversion equipment 3 places the centre of two skeleton 1-a, 1-b, and a decompression capacitor 3 is installed in arbitrary skeleton 1-a, 1-b is last and form integral structure.
Referring to Fig. 2; in the electronic element assembly; conversion equipment K, rectifier diode D1, coil CJ and diode D4 are composed in series attraction circuit; decompression capacitor C forms holding circuit; diode D2, coil CJ and diode D3 are composed in series freewheeling circuit; capacitor C 1 and resistance R 1 are composed in series the RC protective circuit or piezo-resistance is connected in parallel on power supply A1, A2 two ends; capacitor C 2 and resistance R 2 are composed in series the RC protective circuit or piezo-resistance is connected in parallel on coil CJ two ends, and discharge resistance R is connected in parallel on decompression capacitor C two ends.Decompression capacitor C is for exchanging the high withstand voltage electric capacity of 800V.During work, when power supply A1 is positive potential, the electric current that then provides provides Rectified alternating current to coil CJ after diode D1 rectification, moving behind certain position when the suction of contactor iron core, conversion equipment K disconnects, and decompression capacitor C seals in the circuit, at this moment diode D2, D3 play the afterflow effect, power supply provides Rectified alternating current through decompression capacitor C to coil CJ, makes the iron core sticking under low-voltage, has reached the purpose of silent power-saving.When power supply A1, A2 two ends dead electricity, the contactor iron core discharges, and resistance R is connected in parallel on power supply A1, A2 two ends by the RC protective circuit that capacitor C 1 and resistance R 1 constitute for decompression capacitor C discharge electricity, prevents line over-voltage; Be connected in parallel on the RC protective circuit that constitutes by capacitor C 2 and resistance R 2 at coil CJ two ends, prevent coil CJ overvoltage; Capacitor C 1 and resistance R 1, capacitor C 2 and resistance R 2 can be replaced by a piezo-resistance.
The technical scheme of present embodiment can be applied to the alternating electromagnet and the various contactor of similar structures.
The utlity model has following characteristics:
1, owing to adopt the mode of Alternating Current Power Supply, dc operation, iron core does not have active loss; The sticking state has adopted decompression capacitor, and making electromagnetic system is capacitive load, improves the line power factor, has obtained significant power savings, reduces noise, and has reduced temperature rise, has prolonged the useful life of contactor.
2, decompression capacitor can adopt and exchange the high withstand voltage electric capacity of 800V, has solved the often breakdown phenomenon of available technology adopting direct current 630V electric capacity.
3, because the attracting process of A.C. contactor is a dynamic process, its dynamic process and closing phase angle have substantial connection.Different closing phase angles, dynamic process are just different.Essence changes if will take place for the energy-saving circuit difference of A.C. contactor, the dynamic characteristic of its electromagnetic system.If parameter designing is unreasonable, under some closing phase angle, phenomenon can appear once not closing a floodgate, and this will have a strong impact on the reliability of contactor work.Adopt the height of the closed average speed of armature of energy-saving run than no energy-saving run.Therefore we know, the armature closing speed increases, and its Impact energy also increases, and whole contactor shook caused contact secondary spring probability when this certainly will strengthen owing to the bounce-back of armature collision or closure.The utility model adopts the dedicated convert device by the design of magnetic system energy saving optimizing, does not take the contactor auxiliary contact, brings convenience for wiring reaches the solenoid of directly replacing former A.C. contactor; And conversion equipment has played the effect of total head attracting state switch transition, keep the sticking state by decompression capacitor, so not only guaranteed the reliable of magnetic system, and improved the contactor operating characteristics and cooperated, the kinetic energy of avoiding closing a floodgate is excessive and cause the transition collision of magnetic system, thereby suppresses the secondary vibrations spring of contact.
In sum, the utility model not only has economize on electricity, material-saving, noiselessness and characteristics easy to use, But also improved the contactor operational reliability, improve service life.
