Embodiment
Below with reference to accompanying drawing, to upper wire outlet seat and the capable detailed description of pole Zhong of pole of the present utility model.
Embodiment 1
With reference to figure 1, the present embodiment provides a kind of upper wire outlet seat of pole, upper wire outlet seat is fixedly mounted on the upper end of vacuum interrupter in pole, it comprises: base body 10, the wire hole 11 axially arranged along base body 10 and the installation groove 12 be communicated with wire hole, described installation groove 12 is arranged in the top and bottom of base body 10, the described installation groove 12 of upper end is for the pole that is located by connecting, and the described installation groove of upper end is used for being fixedly connected with terminal block.Described base body 10 has the Part I 13 be electrically connected with the quiet end of vacuum interrupter, base body 10 is fixedly attached on pole by Part I 13, in general connected by being flexible coupling between base body 10 and the quiet end of vacuum interrupter, thus play the effect of conduction, when vacuum interrupter conducts, by heat more for release on base body 10, each contact temperature in quiet end and vacuum interrupter is caused to raise, described Part I 13 place be heat gather place, one-body molded on described Part I 13 have Part II 14, described Part II 14 is one-body molded on outer wall to be had for increasing described base body 10 radiator structure 15 long-pending with air contact surfaces, the extension area of described radiator structure 15 is larger, be suitable for the capable heat exchange of external environment Zhong of telling somebody what one's real intentions are with temperature, thus reduce the temperature of pole inside.It should be noted that, existing upper wire outlet seat top is formed with an outlet row, and the body demand fulfillment assembling demand of upper wire outlet seat, therefore be difficult to directly process radiator structure 15 on upper wire outlet seat body, thus adopt split type hard-wired connected mode between radiator structure and upper wire outlet seat, this structure not only cost is higher, and due to heat exchanger effectiveness lower, radiating effect is also undesirable.And the upper wire outlet seat of the present embodiment, by be used for hard-wired Part I 13 in base body 10 and be used for dispelling the heat Part II 14 one-body molded, thus add the efficiency of heat trnasfer, improve radiating effect, secondly, the outlet row of bar-like member is arranged on installation difficulty on base body 10 compared in prior art by the structure installment such as the cooling stand being used for dispelling the heat to upper wire outlet seat on assembly difficulty greatly reduce.Simultaneously because the base body 10 that structure is comparatively complicated is disposable one-body molded, and do not need to process wire outlet seat and cooling stand respectively, effectively save die cost, manufacturing cost is also decreased.
Radiator structure 15 in the present embodiment is described in detail below in conjunction with Fig. 2:
In the present embodiment, described radiator structure 15 comprises the some radiating fins 151 extended along described base body 10 outer wall radial direction, see Fig. 1, two sides of radiating fin 151 are owing to having larger area, the object of heat exchange can be played rapidly, help the temperature reducing a contact in vacuum interrupter, thus ensure that the long-term normal of vacuum interrupter uses.Zhong mono-step, some described radiating fins 151 are along the circumferential spaced set of described outer wall.
And be out of shape as the one of above-mentioned execution mode, the plane of described radiating fin 151 can also be the axis setting of vertical base body 10, and be arranged on the outer wall of base body 10, the radiating fin of this form can play good radiating effect equally, but compared to the execution mode shown in above-mentioned Fig. 1, between this radiating fin 151, the dust in gap is easily piled up, and is difficult to cleaning, can affect radiating effect after dust accretions is too much.
In the present embodiment, some described radiating fins 151 are shaped on base body 10.Radiating groove 152 is formed between adjacent described radiating fin 151, described radiating groove 152 be positioned at the slot bottom width that outermost A/F is greater than described radiating groove 152, the benefit arranged like this is, accumulates in the dust between radiating groove 152, easily move by airflow influence, avoid accumulating.
Zhong mono-step, the bottom land of described radiating groove 152 is at the bottom of deep-slotted chip breaker, thus better avoids dust to accumulate.
In the present embodiment, described radiating fin 151 side outwardly at least comprises one section of curved profile, under onesize installing space, the radiating fin 151 with curved profile can possess larger surface area, effectively avoid in installation process, the technological deficiency that staff easily stabs by the wedge angle of general Rectangle Fin Radiator 151 simultaneously; As a kind of execution mode of radiating fin 151, the described curved profile of radiating fin 151 described in several is spherical in shape around described base body 10, not only maintains higher cooling surface area, also improves coefficient of safety simultaneously.
Embodiment 2
See Fig. 3, the present embodiment provides a kind of pole, and it comprises the upper wire outlet seat being arranged on vacuum interrupter upper end and the lower wire outlet seat 20 being arranged on vacuum extinction lower end, and described upper wire outlet seat is the upper wire outlet seat described in embodiment 1.
In the present embodiment, described lower wire outlet seat 20 is provided with for increasing the described lower wire outlet seat 20 lower wire outlet seat radiator structure 21 long-pending with air contact surfaces, described lower wire outlet seat radiator structure 21 can be the structure of the radiating fin described in embodiment 1 or the lower wire outlet seat of other increases and outdoor air contact area, to play the object reducing each contact temperature of vacuum interrupter, ensure that outdoor vacuum circuit-breaker long-term stability is run.
Obviously, above-described embodiment is only for clearly example being described, the restriction not to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And thus the apparent change of extending out or variation be still among the protection range that the utility model creates.
