As optimization technique means: the insulated spacers are symmetrical above and below, bilateral symmetry.Symmetrical structure, so that manufacture It is easy for installation, realize electric insulating quality symmetrically and evenly.
As optimization technique means: the outside of the bus bar coats polyester film.Polyester film good combination property, energy It is enough well adapted for marine climate, stable structure is reliable.
As optimization technique means: multiple bus bars are arranged in parallel in the length direction of shell, and the length of shell is L, Middle L >=200mm.To guarantee the electrical safety distance between bus bar.
As optimization technique means: the width of shell is B, wherein B >=150mm.The size can better ensure that bus bar Between have enough electrical safety distances.
As optimization technique means: the bus bar phase line is not less than 19 millimeters to shell linear distance, and phase line is to phase line Linear distance be not less than 25.4 millimeters, zero curve distance to the ground reaches the opposite mutually and relatively half of distance, to guarantee to charge There is enough electric clearances between body.
As optimization technique means: the phase line in bus bar is not less than 32 millimeters, in bus bar to shell creepage distance Phase line is not less than 50.8 millimeters to the creepage distance between phase line.Increased in size reduces the possibility of breakdown to reach safe distance Property.
As optimization technique means: the bus bar uses the film-insulated encapsulating of PET high temperature resistance polyester, at insulated spacers 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 It is well adapted for marine climate, stable structure is reliable.
In order to guarantee the electrical safety distance between bus bar 2,4 bus bars 2 are set in parallel in the length direction of shell 1 It sets, the length of shell 1 is 200mm.To guarantee the electrical safety distance between bus bar 2.
In order to better ensure that between bus bar 2 there is enough electrical safety distances, the width of shell 1 is 150mm.The ruler Very little can better ensure that has enough electrical safety distances between bus bar 2.
In order to guarantee there is enough electric clearances between electrical body, 2 phase line of bus bar is not less than 19 to 1 linear distance of shell Millimeter, phase line are not less than 25.4 millimeters to the linear distance of phase line, and zero curve distance to the ground reaches opposite mutually and relatively distance Half, to guarantee that there is enough electric clearances between electrical body.
In order to avoid generating water bridge because of condensation, the phase line in bus bar 2 is not less than 32 millimeters to shell creepage distance, bus Phase line in row 2 is not less than 50.8 millimeters to the creepage distance between phase line.Water bridge is generated to avoid because of condensation, is formed conductive Face.
Reliability service in the case where in order to guarantee to have condensation inside bus duct, bus bar 2 are thin using PET high temperature resistance polyester Film insulation encapsulating, uses whole insulating sleeve, and insulating sleeve is all closed on each section of busbar at insulated spacers 3.It keeps away Exempt to have relatively and with respect to phase and climb electric approach, reliability service in the case where to guarantee to have condensation inside bus duct can also be prevented Only erosion of the sell-fog steam of marine climate environment to busbar.
The present invention effectively increases creepage distance, and reduction climbs electric approach, avoids ponding, avoids generating water bridge conduction, reduce Influence of the marine climate to bus duct, can effectively promote the electrical security of air insulation bus-slot.
It is specific embodiments of the present invention that the air insulation bus-slot of marine climate is adapted to shown in figure 1 above, body Reveal substantive distinguishing features of the present invention and progress, shape can be carried out to it under the inspiration of the present invention using needs according to actual The equivalent modifications of shape, structure etc., the column in the protection scope of this programme.
