Abstract
The utility model discloses an inclined polar locking type decompression and release alternating current contactor with noiseless and saving electricity. The main electric magnet of the inclined polar is attracted instantly, a minor auxiliary electric magnet is held in a micro electricity mode, and other machines are controlled in a method of power cut and release. The utility model has the advantages of energy saving, high reliability, and large starting torque.
Description
The utility model belongs to a kind of silent power-saving A.C. contactor.
A.C. contactor is a kind of common low-tension device, it is by holding electromagnet electric energy to be converted to the appliance switch that mechanical energy drives contact closure or disconnection, and A.C. contactor in use will consume the electric energy of some, owing to be widely used, long-term charging operation, the accumulative total power consumption is appreciable.Therefore, many people study the power-saving technique of A.C. contactor.With regard to the oblique pole-face of domestic existing (claiming twisting again) and mechanical lock buckle, two kinds of novel contactors of no-voltage trip formula, the former major advantage is that starting torque is big, when number of ampere turns reduces 46% than original system, starting torque is about original 2 times (seeing shown in Figure 3), if keep original moment constant, then can economize on electricity about 40%, joint copper cash about 20%, save silicon steel disc about 10%.Its shortcoming is the noise that brings for fear of because of the charged maintenance of electromagnet, needs oblique pole-face is carried out grinding, and the installing divided magnetic ring, thereby make processed complexization, be unfavorable for producing in batches, and the remanent magnetism gap is difficult for guaranteeing, thereby the popularization of this technology is restricted.The latter's advantage is to realize " little electricity keeps " and economize on electricity, but because of main electromagnet still adopts flat adhesive, so starting torque is littler than oblique pole-face.
The purpose of this utility model is to make A.C. contactor further perfect on the prior art basis, reaches the effect of further economize on electricity material-saving, (simultaneously, bigger starting torque is arranged again, tiltedly pole-face can not need grinding, has cancelled divided magnetic ring and remanent magnetism gap), simplify the main electromagnet processing technology.
The technical solution of the utility model is: the form that adopts oblique pole-face magnetic system to combine with mechanical lock buckle, no-voltage trip formula system:
One, set up two groups of electromagnet, promptly main electromagnetism (rise employ) and secondary electromagnet (keep with) make A.C. contactor realize starting by mechanical mechanism, adhesive, keep operation and cut off the power supply three kinds of states of release.
Two, operation principle is changed into the new operation principle of " instantaneous energising adhesive, little electricity maintenance, outage discharge " by traditional " energising adhesive; charged maintenance, outage discharge ", main electromagnet changes the oblique pole-face of not being with divided magnetic ring into by the original flat pole face with remanent magnetism gap, band divided magnetic ring, has cancelled the remanent magnetism gap.In addition, more reasonable in order to construct, make secondary electromagnet longer to the power arm of vertical rod (15) motion.The utility model has been done improvement to mechanical lock buckle, no-voltage trip mechanism: the downside rather than the upside that secondary electromagnet are arranged on horizon bar (7).
Now in conjunction with the accompanying drawings, the utility model is further described (with reference to Fig. 1, Fig. 2).
Form main electromagnet by (8) initiatively unshakable in one's determination, main fixed core (11) and main coil (10) and promptly play motor magnet.(8) initiatively unshakable in one's determination are fixed on the cantilever (9), and cantilever (9) is fixed in the rotating shaft (5), and (8) initiatively unshakable in one's determination are by cantilever (9) (5) rotation around the shaft.Main fixed core (11) and main coil (10) are fixed on the base plate (13) by main coil frame (12), and base plate (13) is fixed on the mounting panel (16).
By pair moving (19) unshakable in one's determination, secondary fixed core (18) and secondary coil (17) are formed secondary electromagnet and are promptly kept electromagnet.Secondary moving (19) unshakable in one's determination can rotate around vertical rod support (14) by vertical rod (15), and secondary fixed core (18) and secondary coil (17) are fixed on the baffle plate (2) by secondary coil support (4), and baffle plate (2) is fixed on the base plate (13).
The course of work: during energized, main coil (10) and secondary coil (17) are switched on simultaneously, but main electromagnet suction is far longer than secondary electromagnet suction.During the main electromagnet adhesive, driving horizon bar (7) by cantilever (9) and rotating shaft (5) rotates towards the lower left, this moment, the pair of secondary electromagnet was moved (18) unshakable in one's determination under the electromagnetic force effect, move to the upper left side around vertical rod support (14) by vertical rod (15), when pair moving (19) unshakable in one's determination and secondary fixed core (18) adhesive, vertical rod (15) pins horizon bar (7), vertical rod (15) promotes the power supply that limit switch (1) travel switch has cut off main coil (10) simultaneously, makes whole contactor be in mechanical lock buckle, little electricity is kept closed.When outage, secondary electromagnet loses electromagnetic attraction, under the effect of the push rod spring (6) of limit switch (1), horizon bar (7) is threaded off, and makes (8) initiatively unshakable in one's determination to get back to open position under the effect of reaction spring (3).
The utility model is component invention. Oblique pole-face magnetic system and mechanical lock buckle, no-voltage trip formula system are combined, given full play to advantage separately, overcome shortcoming separately. Tiltedly the major advantage of pole-face magnetic system is that the main electromagnet starting torque is big, if keep original suction, then can save part copper cash and silicon steel sheet; Its shortcoming is that oblique pole-face processing technology is complicated, and mechanical lock buckle, no-voltage trip formula system major advantage are energy-conservation, because main electromagnet only need start adhesive, pole-face can not processed again, has cancelled divided magnetic ring and remanent magnetism gap, simplified the manufacturing process of main electromagnet, thereby overcome the shortcoming of the oblique pole-face processed complex of main electromagnet, its shortcoming is to adopt flat pole face, and is littler than oblique pole-face starting torque, combine with oblique pole-face magnetic system, can further save copper cash and silicon steel sheet. So, formed a kind of fairly perfect new A.C. contactor. As social extensive use, have appreciable economize on electricity material-saving and noiseless, the convenient advantage of using, have certain progressive and outstanding practical value than prior art:
More the economize on electricity, material-saving;
2. starting torque is big, reliable operation;
3. obviously reduce electromagnetic noise, improve environment;
4. main electromagnet is not installed divided magnetic ring and remanent magnetism gap, and pole-face unshakable in one's determination need not processing, has simplified manufacturing process.
