Description
Technical field
The utility model relates to vacuum contactor, is specifically related to a kind of splitting lock cushioning mechanism of vacuum contactor.
Background technology
But vacuum contactor has the advantages such as noise is little, long service life frequent operation because of it, in fields such as power plant, petrochemical industry, metallurgy, mining industry, be widely used in the control and protection of high-tension motor.
Vacuum contactor can be combined with high-tension fuse and protective relaying device, becomes the high-pressure vacuum contactor-fuse combined electric apparatus with integrated protection characteristic, also claims combined starter, is commonly called as the F-C loop.Short-circuit protection is undertaken by fuse, and high-pressure vacuum contactor is mainly protected the overload of load etc.Our company number is the utility model patent of CN2750535 on October 19th, 2004, Granted publication, disclose a kind of used for vacuum contactor-fuse combined electric appliance, it comprises vacuum contactor, three fuses and a handcart with electromagnetic control assembly of three vacuum interrupters and three vacuum interrupter divide-shut brakes of one group of control.Disclose the structure of vacuum contactor in the literary composition, as depicted in figs. 1 and 2, three vacuum interrupter 41 peripheries of arc control device module 4 respectively are surrounded by the resilient coating 42 of a silicon rubber, then admittedly are enclosed in the arc control device housing 43 of an epoxy resin insulation material.Three vacuum interrupters 41 in the arc control device housing 43 are flat side by side sleeping.The conductive arm 40 that the quiet end 411 of corresponding three vacuum interrupters 41 connects on the arc control device housing 43 links to each other with corresponding lower stationary contact arm in the switch cubicle respectively.Each conductive arm 40 has an entity 401 made of copper, and entity 401 peripheries are established the containment vessel 402 of an epoxy resin insulation material; Entity 401 rear ends connect the quiet end 411 of vacuum interrupter 41, and front end is that Mume flower contact 403 connects corresponding lower stationary contact arm in the switch cubicle.Corresponding three vacuum interrupters 41 respectively extend back the moved end that an annular wall 432 is blocked this vacuum interrupter 41 on the arc control device housing 43.The moved end of each vacuum interrupter 41 is fixed with a connecting rod 412,432 pairs of annular wall on moved end conducting block 413. arc control device housings 43 of termination, moved end intersection suit of connecting rod 412 and this vacuum interrupter 41 behind this vacuum interrupter 41 should moved end conducting block 413 the position leave a via hole 433, be connected to fuse.The electromagnetic control assembly 5 of vacuum contactor comprises the base plate 56 of drive plate 52 that cassette rack 51 that a bottom and rear side open wide, moved end connecting rod 412 that drives three vacuum interrupters 41 move as divide-shut brake together, tripping spring 53, two groups of closing coils of mutually connecting and hold-in winding 54, a control circuit board 55 and a concave character type.Control circuit board 55 provides switching current to two groups of closing coils of mutually connecting and hold-in winding 54 when closing operation, closing coil and hold-in winding attract long-armed 523 upper armatures 524 of drive plate, tripping spring 53 is compressed, the moved end connecting rod 412 of three vacuum interrupters 41 of three sleeve 520 promotions moves forward on drive plate 52 galianconism 521, realizes closing a floodgate.And then control circuit board 55 provides the maintenance electric current to two groups of closing coils of mutually connecting and hold-in winding 54, closing coil and hold-in winding 54 continue to attract long-armed 523 upper armatures 524 of drive plate, tripping spring 53 is kept compressive state, three sleeves 520 are motionless together with moved end connecting rod 412 maintenances of three vacuum interrupters 41 on the galianconism 521 of drive plate 52, keep "on" position.During sub-switching operation, the moved end connecting rod 412 of three vacuum interrupters 41 of three sleeve 520 promotions is mobile backward on the galianconism 521 of drive plate 52, realizes separating brake.
In the vacuum contactor of foregoing description, the bounce-back because of vacuum contactor during to separating brake requires higher, if bounce-back is larger during separating brake, causes easily that the equipment bang is worn, failure of interruption.
The utility model content
Technical problem to be solved in the utility model is, a kind of splitting lock cushioning mechanism of vacuum contactor is provided, and the bounce-back behind the vacuum contactor separating brake is reduced to zero, stops because the bang that bounce-back causes is worn, the failure of interruption accident.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is, a kind of splitting lock cushioning mechanism of vacuum contactor, be arranged in the vacuum contactor, it comprises at least one oil bumper, be arranged between the upper frame and drive plate of electromagnetic control assembly, wherein, the top of this oil bumper is fixedly installed on the upper frame of electromagnetic control assembly, when separating brake, and drive plate bump oil bumper, oil bumper reacts on drive plate, drive plate drives the vacuum interrupter separating brake, makes its mild arrival open position, so that whole separating brake process overshoot and bounce-back can not occur.
Consider cost and buffering effect, preferred, the quantity of oil bumper is two.
The utility model is owing to having increased oily buffer gear, so that the connecting-disconnecting function of contactor improves greatly.By the use of oily buffer gear, overshoot and bounce-back can be reduced to zero.
