Using whole insulating sleeve, and on each section of busbar, insulating sleeve is all closed.It avoids climbing electricity relatively and with respect to phase
Approach, reliability service in the case where to guarantee to have condensation inside bus duct, prevented also from the salt fog of marine climate environment
Erosion of the vapour to busbar.
The utility model has the advantages that
1, creepage distance is effectively increased, large distance structure is had effectively achieved, ensure that between bus bar there are enough electricity
Gas safe distance, improves electrical security, it is ensured that the reliability service of bus duct.
2, it the characteristics of big creepage distance, avoids condensation and generates water bridge, form conducting surface.
3, bus bar uses the film-insulated encapsulating of PET high temperature resistance polyester, and whole insulating sleeve is used at insulated spacers,
And insulating sleeve is all closed on each section of busbar.It avoids climbing electric approach relatively and with respect to phase, to guarantee in bus duct
There is reliability service in the case where condensation in inside, prevented also from erosion of the sell-fog steam to busbar of marine climate environment.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
In figure: 1- shell；2- bus bar；3- insulated spacers；The first vertical edge of 301-；302- V-shaped groove；The pinnacle 303-；304-
Second vertical edge.
Specific embodiment
Technical solution of the present invention is described in further detail below in conjunction with Figure of description.
As shown in Figure 1, adapting to the air insulation bus-slot of marine climate, 4 buses including shell 1, in shell 1
2, the insulated spacers 3 between bus bar 2 are arranged, the outside of bus bar 2 coats insulating film, the upper/lower terminal portion of insulated spacers 3
It is equipped with symmetrical V-shaped groove 302, the opening and bus bar 2 of V-shaped groove 302 are opposite.
Ponding in order to prevent, the top of insulated spacers 3 are to be made of two symmetrical slopes, and it is α that two symmetrical slopes, which form angle,
Pinnacle 303, wherein 90 °≤α≤160 °.3 pinnacle 303 of insulated spacers of the angular range, can effectively anti-ponding, pinnacle
303 can effectively increase creepage distance.
In order to realize the large distance structure of insulated spacers 3, it is and mother between the pinnacle 303 and V-shaped groove 302 of insulated spacers 3
Be the second vertical edge 304 to match with bus bar 2 between the first parallel vertical edges 301 of line row 2, upper and lower two V-shaped groove 302, insulate every
The distance between the distance between two second vertical edges 304 of part 3 and two first vertical edges 301 difference are 12mm.Effectively realize insulation every
The large distance structure of part 3, while avoiding generating water bridge.
For the ease of installation, insulated spacers 3 are symmetrical above and below, bilateral symmetry.It manufactures easy for installation, realizes electricity symmetrically and evenly
Gas insulating properties.
In order to adapt to marine climate, the outside of bus bar 2 coats polyester film.Polyester film good combination property, can
