Embodiment:
With reference to Fig. 1, Fig. 2 and Fig. 3, high voltage vacuum interrupter seals the phase post admittedly, the phase post 1 main body inboard of sealing admittedly by insulating material be encapsulated with respectively vacuum interrupter 2, with arc control device 2 tighten together on conducting block 3, the movable conducting block that is connected with arc control device 2 moved ends 4 and conducting block 5 down, 4 of following conducting block 5 and movable conducting blocks are connected with the conduction fingertip, and this conduction fingertip is a helical spring 6.Movable conducting block 4 outer surfaces dash and are milled with annular groove 41, helical spring 6 crouches and is located on the movable conducting block annular groove 41, make each circle all with to enclose the following conducting block 5 chamber walls of box movable conducting block 4 outside inconsistent, the formation conducting bridge, and can descend 51 slips of conducting block 5 inner chambers freely by maintenance activity conducting block 4.In addition, movable conduction annular groove 41 cross sections are the semicircle arcuation, and arc radius is suitable with helical spring 6 radius of spin, makes helical spring 6 neighborings tangent along more parts and annular groove 41, can improve the area of contact point.And with the contacting of following conducting block 5 inner chambers 51, also be subjected to certain compressing distortion because of helical spring 6, it is wideer that its points of tangency becomes, and increases conductive contact surfaces.
As Fig. 1, Fig. 2 and Fig. 3, phase post 1 outer surface is provided with some walings 11 away from lead end one side of upper and lower conducting block 3,5, and remaining surface is provided with horizontal full skirt 12 and draws back the distance of holding with ground.Reinforcement 11 plays reinforcing and increases the mechanical strength of post mutually, overcomes the fault of construction that existing phase post back embeds the strong point, and it is more even that high voltage electric field is distributed.
As Fig. 1, following conducting block 5 is provided with to link up and surrounds inner chamber 51 and outside ventilation hole 52, be shown in dotted line among the figure, and phase post 1 corresponding conducting block ventilation hole 52 down is provided with air duct 13, is beneficial to inner hot gas distribute, and reduces temperature rise.In addition, seal resilient coating 21, then outside it, be cast with insulating material and form phase post 1 main body with elasticity and tolerance high pressure in vacuum interrupter 2 outsides.Can guarantee like this when producing casting process and arc extinguishing and stop up work, because of two kinds of media expansion coefficients not coplanar cause cracking, effectively overcome the influence of factors such as environment, make product reliable, reach non-maintaining purpose.
With reference to Fig. 4 and Fig. 5, helical spring 6 each circle all become skewed crouching to be located on the movable conducting block annular groove 41, because each circle of the spring that tilts all has upright elasticity trend and the radial compression force that rises, keep it closely to electrically contact with following conducting block 5 all the time.Easier being compressed of spring when skewed spring is upright, the resistance of reduction activity conducting block 4 actions greatly.Crouch if be embedded in the annular groove 41 in order to adapt to tilting screw spring 6, movable conducting block annular groove 41 cross sections are major axis semiellipse arcuation, and major axis is suitable with the helical spring radius of spin, and each circle of skewed spring can be matched with it, form double some contact, reach maximum contact area.Annular groove 41 on the described movable conducting block is perpendicular to movable conducting block 4 directions of motion, and 41 one-tenth one of each annular grooves are closed whole.Each annular groove is embedded a helical spring 6, according to different voltage environment, and changeable annular groove 41 and helical spring 6 quantity.Movable conducting block 4 is a circular concentric with the cross section that cooperates that is enclosed in its outer following conducting block 5, this groove structure, and the conduction fingertip that it is embedded also can be ball.If both cooperation cross sections are rectangle, the conduction fingertip of its four sides mating surface also can adopt roller.In any case but, be good with helical spring especially.In addition, annular groove 41 also can become helical structure to be laid in movable conducting block 4 outer surfaces, equally also can reach the purpose that is embedded helical spring 6.
In addition, above-mentioned semicircle arcuation groove, major axis semiellipse arcuation groove are removed, especially are good with the angle groove that helical spring 6 at least can be tangent with two limits of annular groove 41, forms multiple spot and electrically contact in movable conducting block annular groove 41 cross sections.
With reference to Fig. 6, this is a generalized section that the utility model is applied to fixed phase post; Fig. 7 aly applies to rotary pole generalized section with the utility model, can form isolation fracture, expansion circuit breaker, on-load switch function.
In sum, the related helical spring of the utility model conduction fingertip can apply on handcart-type, the fixed and rotary rod structure mutually as the bridge construction that is electrically connected between movable conducting block and following conducting block, can make formal dress and the side post series of pretending.
