Description
The utility model is a kind of economize on electricity magnetic switch, belongs to appliance switch.
Employed electromagnetic force switch in industrial production at present, all be to make the coil of switch pass to alternating current, with the electromagnetic attraction that electromagnet produced, make electrical contact under certain pressure, contact conducting, for the operation of keeping switch is used, must keep passing to big electric current and consume much electricity, simultaneously because the magnetic force that alternating current produced has periodically strong and weak the variation, so electromagnet also is to tremble with the power of magnetic force to the pressure of electrical contact, thereby cause the contact wearing and tearing of electrical contact very fast, shortened the life-span of switch.
The purpose of this utility model is achieved through the following technical solutions: pull bar 1 is housed in switch case, and dress stage clip 2 on the pull bar 1, moving contact 3 is equipped with in the stage clip bottom, the bottom shock mount 10 of moving contact 3, spring 10 bottoms contact with the switch case standing part.Fixed contact 8 also is housed in the switch case of moving contact 3 relevant positions.Be processed with pull bar shelves 6,7 in the bottom of pull bar 1.Push rod 11 1 ends can contact with very heavy card 9, and the other end is connected with depression bar 26, and extension spring 12 1 ends are connected with very heavy card 9, and extension spring 12 other ends are fixed on the switch case fixed position.Very heavy card 9 is connected with housing by movable axis 5.Extension spring 17 1 ends are connected with depression bar 26, and the other end is connected with the switch case fixed position.Depression bar 26 is contained on the pressure shaft 15, and pressure shaft 15 is fixed on the switch body, sensitive switch 14 be contained in depression bar 26 corresponding housings on.Push rod 16 is contained on the housing, and contacts with sensitive switch 14.Depression bar 20 is connected with depression bar 26 by pressure shaft 18, and eccentric wheel 19 is connected with depression bar 26 by axle, and eccentric rod 22 is connected with eccentric wheel 19, and spring 21 1 ends are connected with depression bar 20, and the other end is connected with eccentric rod 22, and electromagnet 25 is contained on the depression bar 26.Actuating coil 23, operation coil 24 is installed on deciding in the iron 27 of switch case, decides iron 27 and is contained in the switch case, and push rod 4 also is contained in the switch case.
The utility model operation principle such as Fig. 1 are as showing, the part that this figure indicates G is the housing standing part of this switch.
When actuating coil 23 fed electric current, electromagnet 25 sucked decline and by depression bar 20, presses pull bar shelves 6, pull bar 1 is descended, when reducing to certain position, pull bar shelves 7 are collided with very heavy card 9, because very heavy card top is domatic, movable axis 5 is arranged at the bottom, when pull bar 1 descended, very heavy card 9 was swung to the right side, when pull bar shelves 7 are crossed long mouthful of 13 places, very heavy card plane when pull bar 1 continues to descend, because the effect of extension spring 12 pulling force, very heavy card 9 is reposition again.This moment, moving contact 3 was owing to be subjected to the pressure effect of spring 2, be pressed in firmly on the fixed contact 8, make switch in running order, when this moment, pull bar 1 continuation descended, eccentric rod 22 withstands on the push rod 4, eccentric wheel 19 is rotated, though electromagnet 25 declines this moment, but depression bar 20 is because eccentric effect, and pull bar shelves 6 are left in action in the opposite direction, make electromagnet 25 and depression bar 20 break away from the active force that makes progress of pull bar 1, but pull bar 1 and contact 3 are blocked by very heavy card, all can not reset and still in running order.
Because the active force that makes progress of electromagnet moment disengaging pull bar 1 makes it to quicken descending motion, when dropping to the appropriate location, depression bar 26 presses sensitive switch 14 actions, disconnects coil 23, and makes 24 and 23 polyphone energized, moments of 23 outages just electromagnet lose reaction force suddenly and in the high speed descending motion, by means of the coherence effect, though 23 outages, electromagnet still continues to quicken to descend, up to decide iron 27 adhesives, and connect 24, this moment, starting button broke away from operation, can decontrol.
Because 23 and 24 liang of coil polyphones insert power supply, electric current is reduced to keeps a less magnetic flux, but still can make very heavy card 9 can block pull bar 1, make the switch operate as normal, but because the electric energy that electromagnet consumed, have only below 1/5th of the equal switch of general use institute consumed power, thereby can economize on electricity more than 80 percent.This mechanism reduces the wearing and tearing of silver tipped contact because electrical contact is not subjected to the influence of electromagnet vibration, thereby the useful life of having improved switch.
When disconnecting 24, by the effect of spring 17, electromagnet resets, the effect of spring 21, and eccentric rod resets.Because push rod 11 compression rods 26 press, to back down very heavy card 9 and made it to leave pull bar shelves 7, pull bar 1 moving contact 3 was subjected to spring 10 elastic force effects and resetted (also can draw back, but need change a direction) this moment, and switch is in off-position, restarts to treat next time.The electric operation line map of this electromagnetic switch is seen Fig. 2.It among the figure switch sections.
This magnetic switch makes electromagnet when work owing to adopted very heavy card, is not subjected to the pressure of contact, and the reaction force of spring is so have only very little magnetic flux can keep the adhesive electromagnet.When being used to start, because of being the short time, so can make coil adopt high current density, iron core adopts high magnetic flux density, thereby has also dwindled the volume of electromagnet, can save part silicon steel sheet and copper cash.As increasing one group of bridge-type drag flow device, provide DC control supply better.Can make efficient higher.According to above-mentioned gained conclusion, magnetic switch institute consuming electric power is to produce gravitation to satisfy switch work required, overcomes iron core gravity pressure and the required pressure of contact.Being formulated general magnetic switch is:
F＝Ft＋Fc
And this magnetic switch is: F=Ft+Fc-Fc
Ft+Fc-Fc＜Ft+Fc clearly
Fc is the saving part, so have only economizing on electricity more than 80% below 1/10 of Fc according to general magnetic switch Ft.
F=magnetic force sum total
Ft=electromagnet self gravitation
Fc=contact reaction force.
The utlity model has the saving electric energy, the distinguishing feature of long service life.
Now in conjunction with the accompanying drawings the utility model is described in further detail.
