Abstract
The invention is concerned with the great capacity vacuum loading switch, it includes: the moving contact with the moving main contact and the moving arc contact, the fixed contact with the fixed main contact and the fixed arc contact, the main screen cover, the up and down guiding poles, and the ceramic shell. The upwards active guiding pole, with the fixed arc contact on the bottom, is with the downwards active guiding pole; with the moving main contact on the top part active on the up-guiding set; the moving arc contact is on the moving main contact. The invention applies the parallel transfer principle bases on the double fellows' foundation, which uses two pairs of main contacts and arc contacts independently, achieves the single vacuum arc interrupted room bear the weight of the great quantity of rated current and the re/closing short circuit current possible.
Description
Technical field
The present invention relates to a kind of on-load switch that is used in electric power output and the transmission system, is a kind of high capacity vacuum load switch specifically.
Background technology
In common on-load switch vacuum interrupter, be provided with a moving contact and a fixed contact.Cut-off and the rated current of short circuit current are carried by finishing with a pair of contact.The drawback of the vacuum interrupter maximum of this prototype structure is to satisfy to be difficult to have simultaneously the long-term through-current capability of big rated current under the prerequisite that big short circuit current cut-offs in the single vacuum arc control device.
Summary of the invention
The purpose of this invention is to provide a kind of novel vacuum interrupter, it can overcome existing shortcoming in the prior art, the ability that makes single arc control device have the big rated current of carrying simultaneously and cut-off big short circuit current.
The object of the present invention is achieved like this: it comprises dynamic and static contact, main shield cover, upper and lower moving conductive rod, ceramic package, it is characterized in that: moving contact is made up of moving main contact, moving arcing contact, fixed contact is made up of quiet main contact, quiet arc contact, the quiet arc sets of contacts is contained on the moving conductive rod, and last moving conductive rod activity is assembled on the fairlead; Moving main contact is arranged on down the upper end of moving conductive rod, and following moving conductive rod activity is assembled in down on the fairlead, and moving arcing contact is assembled on the moving main contact.
Above-mentioned upper and lower moving conductive rod periphery is provided with bellows and bellows shield cover respectively.
Advantage of the present invention is: on the bi-bellow basis, utilize principle of transfer in parallel, big specified current load and big cut-offfing respectively of short circuit current are finished by two pairs of relatively independent main contacts and arcing contact, realized the ability that the single vacuum arc control device have the big rated current of carrying simultaneously and cut-off big short circuit current by as above designing from practical significance.

Embodiment
See Fig. 1,2, concrete structure of the present invention is as follows: moving contact is made up of moving main contact 13, moving arcing contact 14, and fixed contact is made up of quiet main contact 3, quiet arc contact 15.Quiet arc contact 15 is assembled in the lower end of moving conductive rod 1, and last moving conductive rod 1 activity is assembled on the fairlead 2, in last moving conductive rod 1 periphery bellows 16 and bellows shield cover 17 and quiet main contact 3 is set; Moving main contact 13 is connected in down the upper end of moving conductive rod 11, and following moving conductive rod 11 activities are assembled in down on the fairlead 10, and moving arcing contact 14 is assembled on the moving main contact 13.In following moving conductive rod 11 peripheries bellows 7 and bellows shield cover 8 are set.Dynamic and static arcing contact 14 and 15 vertical each other mutually magnetic field structure of contact terminals, dynamic and static main contact 13 and 3 is used for carrying big rated current, adopts the good fine copper of electric conductivity as contact material.Dynamic and static arcing contact 14 and 15 is used for cut-offfing big short circuit current, and its contact material is a chromiumcopper.Periphery at switch is assembled ceramic packages 5 by the metal sealing ring 4,9 at two ends, and main shield cover 6 is set in ceramic package 5, constitutes vacuum interrupter.One end of following moving conductive rod 11 is connected with operating mechanism by insulated tension pole, and last moving conductive rod 1 end is connected to the energy-stored spring (not shown) after by insulated tension pole.
Operation principle: vacuum interrupter of the present invention is when closing a floodgate, following moving conductive rod 11, moving main contact 13 and moving arcing contact 14 move upward to position A under operating mechanism drives after, moving arcing contact 14 is in contact with one another move upward (the also not contact of dynamic and static main contact this moment) with quiet arc contact 15, and the energy-stored spring energy storage of giving last moving conductive rod 1 end.After dynamic and static arcing contact moves to position B, dynamic and static main contact 13,3 begins contact, and it is reliable closed under the effect of contact pressure, this moment, most of electric current was transferred on dynamic and static main contact 13 and 3 by dynamic and static arcing contact 14 and 15, promptly finished big current load task by dynamic and static main contact 13,3.Dynamic and static arcing contact 14,15 contact earlier at position A place when closing a floodgate is satisfied in upper and lower contact motion, and after continuing together afterwards to move upward to position B, dynamic and static main contact begins contact.Because the main contact electric conductivity is more far better than arcing contact, thus main, arcing contact all reliably the most of current transfer in contact back promptly carry big rated current to main contact by main contact; During separating brake, following moving conductive rod 11 and moving main contact 13 and moving arcing contact 14 begin to do the separating brake motion downwards from position B under spring operating mechanism drives, the energy-stored spring energy of last moving conductive rod 1 end discharges, moving conductive rod 1 and quiet arc contact 15 are moved downward together with moving arcing contact 14, this moment, dynamic and static arcing contact 14,15 still was in conducting state, and dynamic and static main contact 13,3 has separated fully.When the energy of energy-stored spring is 0 (promptly getting back to position A again), quiet arc contact 15 transfixions.And following moving conductive rod 11 and moving arcing contact 14 and moving main contact 13 continue to move downward.At this moment, dynamic and static arcing contact begins to separate, and opens in scope whole, and electric arc burns on dynamic and static arcing contact.This moment, electric arc was extinguished easily owing to the existence in magnetic field.Because main contact separates earlier during separating brake, this moment, arcing contact still was in contact condition, and arcing contact just began to separate after main contact separated certain distance, and then the task of cut-offfing of short circuit current is finished by arcing contact.Arcing contact adopts vertical magnetic structure to increase the control action of magnetic field to electric arc, improves the break performance of whole vacuum interrupter greatly.
