The reinforced sheath and fixed plate are integrative-structures, referred to as stiffening device;Anchor ear and terminal plate are integrative-structures, are claimed It is termination;The outside of two parts stiffening device matches two parts termination, and the inner chamber after matching is circle, and circular is interior Footpath is equal to or slightly less than the external diameter of binding post, is an entirety by binding post and stiffening device and termination fastening.
Binding post is arranged on mounting flange, and fixed board diameter matches with the mounting flange of binding post, and mounting flange sets Put on liter dais, fixed plate is fixed by fixture with mounting flange.
Using the utility model, termination matches with stiffening device, and so, downlead is passed by wire clamp, terminal plate The most of load for being delivered to binding post is just delivered on liter dais by bracing means, makes the load being finally applied on binding post Only surplus small part.
The beneficial effects of the utility model are:Can quick in the case where sleeve pipe is not dismantled, conveniently and effectively strengthen Transport the mechanical strength of power station main transformer bushing binding post, reduce and even prevent the hidden danger of prior art, installation operation is simple, when Between short, effect it is obvious.
Brief description of the drawings
Fig. 1 is the utility model embodiment schematic diagram;
Fig. 2 is the utility model embodiment termination and stiffening device structural representation;
In figure:Binding post 1, terminal plate 2, wire clamp 3, downlead 4, liter dais 5, conservator 6, wiring hole 7, anchor ear 8, reinforcement shield Set 9, fixed plate 10, fastener 11.
Specific embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
A kind of extra-high voltage conduit connection post bracing means, comprising binding post 1, terminal plate 2, wire clamp 3, downlead 4, liter dais 5th, conservator 6, wiring hole 7, anchor ear 8, reinforced sheath 9, fixed plate 10, fastener 11, conservator 6 are provided with liter dais 5, rise dais 5 Binding post 1 is provided with, binding post 1 connects wire clamp 3 by terminal plate 2, and wire clamp 3 is connected with downlead 4;Its special feature is:Institute State the outside of binding post 1 and be provided with two reinforced sheaths of semicircle shape 9, by the tight of binding post 1;Two reinforced sheaths of semicircle shape 9 bottom is respectively equipped with two fixed plates 10, and two fixed plates 10 are fixed on liter dais 5 by fastener 11 respectively;Two The outside of the reinforced sheath 9 of semicircle shape is respectively equipped with two anchor ears of semicircle shape 8, and the anchor ear of two semicircle shapes is fastened by bolts Together, two anchor ears of semicircle shape, the reinforced sheath 9 of two semicircle shapes, binding post 1 are tightened together;Two semicircle shapes Anchor ear outside connect terminal plate 2 respectively, terminal plate 2 is provided with wiring hole 7, and wire clamp 3 is fixed on terminal plate 2 by wiring hole 7 On.
The reinforced sheath 9 and fixed plate 10 are integrative-structures, referred to as stiffening device;Anchor ear 8 and terminal plate 2 are one knots Structure, referred to as termination;The outside of two parts stiffening device matches two parts termination, and the inner chamber after matching is circle, circle The internal diameter of shape is equal to or slightly less than the external diameter of binding post 1, and binding post 1 is fastened as one whole with stiffening device and termination Body.
