Abstract
The utility model discloses an energy saving AC contactor, which is composed of a static contact, a moving contact, an electromagnetic coil, a spring, etc. The utility model is characterized in that two eliminator power supplies with opposite polarities are connected in parallel, two eliminator power supplies are connected with the input end of the electromagnetic coil, and a permanent magnet is adopted by the moving contact. When the static contact and the moving contact, the electromagnetic coil is free from electricity, and the electric energy can be saved. The utility model is suitable for the use in an electric drive system.
Description
The utility model belongs to a kind of A.C. contactor.
A.C. contactor is to use the most general a kind of electrical equipment in the Electric Traction, and it is made up of fixed, moving contact, solenoid and spring etc.Give to be enclosed within the solenoid energising of deciding on the contact, decide to produce on the contact magnetic field, the attraction moving contact with decide contact and contact; When cutting off the power supply to solenoid, magnetic field disappears, and under the effect of spring force, moving contact is done homing action.This shows that coil need be subjected to always when moving, deciding the contact contact.
The purpose of this utility model provides a kind of energy saving ac contactor, it moving, decide contact on contacting, coil can not be subjected to.
The purpose of this utility model is achieved in that it is improved on the basis of existing A.C. contactor, and its improvement is:
1, after two opposite polarity rectifier power source parallel connections, receives the input of solenoid;
2, moving contact adopts permanent magnet.
Operation principle is: press start button, connect one of them rectifier power source, solenoid is subjected to electricity, is deciding to produce a magnetic field opposite with the moving contact magnetic pole on the contact, moving contact overcomes spring force, contact with deciding contact, unclamp start button, the electricity circle is not subjected to, the magnetic field of deciding on the contact disappears, but because moving contact is permanent magnet, so moving contact still inhales reliably and decide on the contact, keeps fixed, moving contact to contact; When the needs moving contact resets, press stop button, connect another rectified current, solenoid is subjected to, because this power supply is opposite with the polarity that starts power supply, therefore deciding to produce a magnetic field identical on the contact, under the effect of magnetic force and spring force with the moving contact magnetic pole, moving contact resets, and unclamps stop button.
The utility model compared with prior art because when the contact of fixed, moving contact, coil is not subjected to electricity, has therefore saved electric energy.
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an electrical schematic diagram of the present utility model.
It is improved on the basis of existing A.C. contactor, and its improvement is:
1, after two opposite polarity rectifier power source D1, the D2 parallel connection, receives the input of solenoid C;
2, moving contact adopts permanent magnet.
Operation principle is: press start button QA, connect one of them rectifier power source D1, solenoid 3 is subjected to electricity, decide on the contact 4 to produce one with the opposite magnetic field of moving contact 1 magnetic pole, moving contact 1 overcomes spring 2 elastic force, contact with deciding contact, unclamp start button QA, the electricity circle is not subjected to, the magnetic field of deciding on the contact disappears, but because moving contact is permanent magnet, so moving contact still inhales reliably and decide on the contact, keeps fixed, moving contact to contact; When the needs moving contact resets, press stop button TA, connect another rectifier power source D2, solenoid is subjected to, because this power supply D2 is opposite with the polarity that starts power supply D1, therefore deciding to produce a magnetic field identical on the contact, under the effect of magnetic force and spring force with the moving contact magnetic pole, moving contact resets, and unclamps stop button.
