Abstract
The utility model discloses a vacuum high voltage AC circuit breaker, which comprises an operating mechanism; the operating mechanism is connected with a vacuum arc-extinguishing chamber; a supporting device is arranged between the operating mechanism and the vacuum arc-extinguishing chamber. The utility model has the advantages of small size, simple structure, strong breaking capacity, long service life, no explosion risk and convenient maintenance; the utility model can be widely used for controlling or protecting the electrical power transmission and distribution systems of power plants, substations, etc., especially locations needing breaking important load and frequency operation.
Description
The utility model relates to a kind of switch of alternating current.
Existing alternating current switch generally adopts the form of operating mechanism and switch split, and its volume is big, performance is reliable inadequately, operates cumbersome.
The purpose of this utility model is to provide a kind of operating mechanism and switch AC high voltage vacuum breaker integrated, simple in structure.
Technical solution of the present utility model is:
A kind of AC high voltage vacuum breaker comprises operating mechanism, and it with the difference of prior art is: operating mechanism is connected with vacuum interrupter, forms one, adorns bracing or strutting arrangement between operating mechanism and the vacuum interrupter.
Bracing or strutting arrangement is made up of epoxy resins insulation and connected upper and lower leading-out terminal.Vacuum interrupter comprises by a radome and upper and lower two shells that porcelain tube is packaged into, upper and lower two porcelain tubes are contained in respectively on the upper and lower ring flange, dynamic and static contact is welded in respectively on the dynamic and static conducting rod, static conductive rod is contained on the upper flange plate, weldering one ripple bar on the moving conductive rod, the other end of ripple bar is welded on the lower flange.
The utility model is integrated with operating mechanism and switch; volume is little, simple in structure, connecting-disconnecting function is strong, the life-span is long, no explosion hazard, the maintenance between just; be widely used in the control or the protection switch of electrical power trans mission/distribution systems such as power plant, electric substation, the place that is particularly useful for cut-offfing important load and frequent operation.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is the configuration diagram of vacuum interrupter among Fig. 1 embodiment.
A kind of AC high voltage vacuum breaker, comprise operating mechanism 1, operating mechanism 1 links into an integrated entity with vacuum interrupter 2, adorn bracing or strutting arrangement between operating mechanism 1 and the vacuum interrupter 2, bracing or strutting arrangement is epoxy resins insulation 4 and the connected upper and lower leading-out terminal 5,6 that is contained on the mechanism case 3 of operating mechanism, and upper and lower leading-out terminal 5,6 is connected with vacuum interrupter 2.Vacuum interrupter 2 comprises the shell that is packaged into by a radome 7 and upper and lower two porcelain tubes 8,9, upper and lower two porcelain tubes 8,9 are contained in respectively on the upper and lower ring flange 10,11, dynamic and static contact 14,15 is contained in respectively on moving conductive rod 13 and the static conductive rod 12, static conductive rod 12 is contained in upper flange plate 10, weldering one ripple bar 16 on the moving conductive rod 13, the other end of ripple bar 16 is welded on the lower flange 11, forms the cavity of a sealing thus.Be equipped with on the lower wire end 6 and be flexible coupling 17, being flexible coupling 17 is connected with conductive clip 18 on the moving conductive rod 13.Operating mechanism 1 with the form that vacuum interrupter 2 is connected is: in the bottom of moving conductive rod 13 universal bar end bearing 19 is housed, universal bar end bearing 19 links to each other with lever 20 on the lower wire end 6, the switch spindle 21 of operating mechanism 1 is connected with lever 20 by insulated tension pole 22, power is passed to moving conductive rod 13, make that switch closes, separating brake.Operating mechanism can adopt spring energy-storage formula operating mechanism (alternating current-direct current stored energy operation or manual operation) or other conventionally form.
