Description
Affiliated technical field
The utility model relates to the technical field of electrical control, especially a kind of novel pressure regulation change over switch.
Background technology
At present, the pressure regulation conversion of electrical source of power, generally adopt conventional dual-power transfer switch, its product has: biserial composite contact efficient switch type, air break type and contact type, dual-power transfer switch is by motor or the interlocking of electromagnetic system driving device, thereby realizes two kinds of logic states of " dividing-close ", " close-minute ".Though the product that has indicates " divide-minute " function, also can only thread off and open circuit, and can not realize real logic control, and the logic function of change over switch " branch-minute " is very necessary to the security control of voltage regulation of electric power sources.At present, the change over switch price height of forming by two biserial composite contact efficient switchs, and must add the auxiliary protection device.The change over switch volume of being made up of two air circuits is bigger, throws, cuts speed more than 1.5s, slow movement, and its slide fastener is the latch mechanism easy break-down again, mechanical interlocked so in case the accident that will be short-circuited out of control.The change over switch cost of being made up of two contactors is low, can realize electric, mechanical interlocking, and contactor is under the effect of electromagnetic force, contact closure rapidly up to 20-60ms, but since its contact when disjunction, only depend on the tension of spring, so speed is slow, breaking capacity is poor.Experimental results show that; voltage regulation of electric power sources and duplicate supply conversion have very big difference technically; for example; dual-power transfer switch is applied to the quick conversion between load and power supply commonly used and the stand-by power supply; be mainly and guarantee to power to the load continuously; the pressure regulation change over switch then is applied to the switching between the different voltages with same power supply of load; in the process of voltage transitions; the load that has allows to cut off by phased manner and energized; for example: the load motor of voltage controller power source is changed under the state of high speed rotating; its self-generating electric gesture and supply voltage and transformer induction electromotive force superpose and the over-voltage and over-current of generation; very easily make the contact moment electric arc of change over switch; scorification; if in the process of above-mentioned load being implemented pressure regulation, adopt program control; avoid the over-voltage and over-current peak value of moment, just can protect the safety of pressure regulation change over switch effectively.And adopt dual-power transfer switch substitute electric power pressure regulation change over switch, be not desirable selection.
Summary of the invention
The technical problem that solves: the speed in the time of 1, will improving pressure regulation change over switch " closure " with " disjunction ", rather than the speed of raising transfer process only in this way, just can make the fail safe of pressure regulation change over switch and reliability all obtain substantial raising.The logic function of " divide-minute " 2, is set, realizes the program control in the pressure regulation transfer process, accurately avoid the peak value of transient overvoltage and overcurrent, guarantee the safe operation of pressure regulation change over switch.
The purpose of this utility model is exactly to propose a kind of voltage regulation of electric power sources control realization safe, intelligentized programme controlled novel pressure regulation change over switch of making at above-mentioned technical problem.
Its technical scheme that adopts is: comprise that two contactors 1 and contactor 15 symmetries are fixed on the left and right sides of base 8, and be respectively equipped with upper armature cover 12 in the inboard of two contactors, between two contactors, be fixed with the armature 18 of tractive electromagnet 2 and drawing magnetism 2, the below of armature 18 is bracing frames 7, with bracing frame 7 tops is that fulcrum is connected with lever 11, lever 11 left sides, right two ends are respectively charged in the groove 4 of contactor 1 and contactor 15 upper armature cover 12 separately, the axis hole of lever 11 central points is relative with bracing frame 7 upper gland and penetrate the location by fulcrum shaft 9, be set with stage clip 10 on two pull bars 13, suit catch 6 above it, two pull bars 13 pass the hole of lever 11 fulcrum both sides respectively, two holes of the 17 times horizontal ends in the hole of its upper end and armature are relative and penetrate the location by axle 3, the suit spring 14 that rises on the armature 17.The top that also is included in bracing frame 7 is provided with and increases, slows down towards rubber cushion 5, and tractive electromagnet 2 is fixed between contactor 1 and the contactor 15 by bonded adhesives 16.
The invention has the beneficial effects as follows: adopt a tractive electromagnet to drive two contactors of change over switch, improve the breaking speed of probe of contactor, thereby for realizing the logic function of " divide-minute "; Adopt lever machinery, realize the mechanical interlocked of two contactors; Utilize two contactors auxiliary contact separately, electrical interlocks is set.
