Description
Technical field
The utility model relates to electrical equipment, and more particularly, it relates to a kind of vacuum interrupter.
Background technology
In middle/high-voltage electrical appliance field; vacuum switch is the major electrical equipment equipment for control and protection electric power system; and vacuum interrupter is the core component of mesohigh power switch, Main Function is by can blow-out suppress electric current to avoid accident and occur unexpectedly rapidly after managing the excellent insulating properties of interior vacuum and making mesohigh circuitry cuts power supply.
Vacuum interrupter, has another name called vacuum switch tube, is inside provided with conductive mechanism, and conductive mechanism is used for connecting or segmented current.Described conductive mechanism comprises insulation crust, and the upper and lower two ends of insulation crust are respectively equipped with quiet end casing and moved end cover plate, and insulation crust, quiet end casing and moved end cover plate form a confined space; Confined space comprises the static conductive rod be connected with quiet end casing, the moved end cover plate connected successively, prevents turning round fairlead, bellows and the anti-moving conductive rod turned round fairlead inside and be set with, the fixed contact be connected with static conductive rod in addition and the moving contact be connected with moving conductive rod; As shown in Figure 2, one end end face and moving contact one end end face of fixed contact are oppositely arranged, structurally bellows is connected with moving conductive rod, moving conductive rod is by doing upper and lower displacement campaign thus realizing contact between moving contact and fixed contact and be separated, being turned on or off of electric current, and then realize opening or closing of vacuum switch.
Bellows is mainly undertaken and is ensured that moving electrode moves within the specific limits and keeps the function of high vacuum for a long time, and ensures that vacuum interrupter has very high mechanical endurance.Vacuum switch can produce electric arc in the process of open circuit, electric arc can make the dynamic and static contact of vacuum extinction indoor, each part temperatures such as bellows sharply raises and loss, and they are shortened useful life, so must carry out arc extinguishing process in vacuum extinction indoor.
Current vacuum interrupter Problems existing is: bellows is thinner more crisp, and bellows is connected with moving conductive rod, moving conductive rod does translational motion along the plane vertical with the direction of motion and moving conductive rod axle center there occurs skew, this will cause moving conductive rod discontinuity and cause bellows to deform even breaking, and the useful life of bellows is short thus had a strong impact on the life-span of vacuum interrupter.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of Novel vacuum interrupter, and its advantage is that bellows is more durable, thus vacuum interrupter is more lengthened useful life.
For achieving the above object, the utility model provides following technical scheme:
A kind of Novel vacuum interrupter, comprise insulation crust, the upper and lower two ends of insulation crust are respectively equipped with quiet end casing and moved end cover plate, and described insulation crust, quiet end casing and moved end cover plate form a confined space; Described confined space comprises the static conductive rod be connected with quiet end casing, the moved end cover plate connected successively, prevents turning round fairlead, bellows and the anti-moving conductive rod turned round fairlead inside and be set with, the fixed contact be connected with static conductive rod in addition and the moving contact be connected with moving conductive rod; Fixed contact and moving contact are oppositely arranged, and are provided with buffer part in described bellows between adjacent two ripples.
By adopting technique scheme, make to be provided with buffer part between ripple adjacent in bellows, alleviate by moving conductive rod when doing translational motion along the plane vertical with the direction of motion by buffer part, because moving conductive rod axle center offsets, and cause power bellows being applied to bending twisting, avoid the instantaneous consequence causing deformation even to break of bellows, be designed with buffer part bellows can be made more durable so be provided with buffer part between ripple adjacent in bellows, thus vacuum interrupter is more lengthened useful life.
The utility model is set to further: described buffer part is spring, and the two ends of described spring are fixedly connected with adjacent two ripples.
By adopting technique scheme, make buffer part play a good cushioning effect when being subject to impacting to bellows, the effect that alleviates explosion is played to bellows.
The utility model is set to further: adopt vertical seal structure or flat seal structure during described bellows-welding, solder diameter is 0.4mm.
Be provided with between described bellows and moved end cover plate and prevent turning round fairlead, described anti-fairlead internal sleeve of turning round is equipped with and prevents that turning round fairlead mates the moving conductive rod used, and described anti-turning round between fairlead with moved end cover plate is fixedly connected with by pin.
By adopting technique scheme, making to cause moving conductive rod because of discontinuity and causing to avoid bellows and to deform the situation of even breaking, thus extending the life-span of vacuum interrupter of knowing clearly.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
