Fig. 1 shows the structural representation of a kind of exemplary embodiment of vacuum circuit-breaker.Fig. 2 shows the structural representation in Fig. 1 after vacuum circuit-breaker assembling.Fig. 3 shows the structural representation of the radiator of vacuum circuit-breaker.See Fig. 1, Fig. 2 and Fig. 3, vacuum circuit-breaker comprises the lower copper Connection Block 30 of a vacuum bubbles 20, and a radiator 10.
Wherein, vacuum bubbles 20 is cylindric.Along the axis of vacuum bubbles 20, it has two axial ends.Lower copper Connection Block 30 is arranged at one end of vacuum bubbles 20, namely descends copper Connection Block 30 to be connected to one of them axial end of vacuum bubbles 20.Lower copper Connection Block 30 has multiple plane along its circumference.
Radiator 10 comprises a contact 12 and multiple heat-dissipating fin 14.Contact 12 has a contact end face 122 and a fixing end face 124, and they are all plane (see Fig. 4).In the shows in schematic form shown in the drawings, contact end face 122 is towards lower copper Connection Block 30, and fixing end face 124 deviates from lower copper Connection Block 30, and contact end face 122 is parallel to fixing end face 124.In a kind of exemplary embodiment of the radiator of vacuum circuit-breaker, radiator is processed by the metallic aluminium with good heat conductive performance, and has carried out anodized in spreader surface, to strengthen radiating effect further and the useful life of prolongation radiator.
Contact end face 122 can fit in the circumferential end faces of lower copper Connection Block 30, and contact end face 122 is contacted with the circumferential end faces face of lower copper Connection Block 30.In a kind of schematically enforcement of the radiator of vacuum circuit-breaker, the area of contact end face 122 is not less than the area of the circumferential end faces of the lower copper Connection Block 30 be in contact with it, thus makes the heat of lower copper Connection Block 30 can be passed to radiator 10 fast.
Heat-dissipating fin 14 is convexly equipped in fixing end face 124.Along the circumference of lower copper Connection Block 30, heat-dissipating fin 14 compartment of terrain is arranged in fixing end face 124.In addition, these heat-dissipating fins 14 are parallel to each other, and extend along the axis of vacuum bubbles 20.In the exemplary embodiment shown in Fig. 3, along the axis of vacuum bubbles 20, the size of heat-dissipating fin 14 is greater than the size of contact 12, thereby increases the area of dissipation of radiator.
Be processed with two the second installing holes 32 for the circumferential end faces connecting radiator 10 in lower copper Connection Block 30, and these two the second installing holes 32 are arranged along the circumferential interval of lower copper Connection Block 30.In the contact 12 of radiator 10, along the circumference of lower copper connector 30, the two ends of contact 12 are respectively equipped with first installing hole 126.Along the circumference of lower copper connector 30, first installing hole 126 is corresponding with second installing hole 32, namely the first installing hole 126 communicates with the second installing hole 32, thus make set bolt can be connected to the first installing hole 126 and the second installing hole 32, make radiator 10 can be fixedly connected on lower copper connector 30.
Fig. 4 is the IV direction view of Fig. 3.See Fig. 3 and Fig. 4, each heat-dissipating fin 14 is connected to fixing end face 124 by their root, and the spacing that their distance from top fixes end face 124 is different, namely on the direction perpendicular to fixing end face 124, there is difference in height in heat-dissipating fin 14, make thus can produce stack effect between each heat-dissipating fin 14, accelerate heat radiation further.
In addition, see Fig. 2 and Fig. 4, along the circumference of lower copper Connection Block 30, the line at the top of adjacent heat radiation fin 14 form the geometric center of figure (in Fig. 4 shown in dotted line), the i.e. geometric center of the envelope of heat-dissipating fin 14, is in the axis of vacuum bubbles 20.By this structural design, the Electric Field Distribution of the vacuum circuit-breaker of radiator evenly can be installed.
By installation of heat radiator on the lower copper Connection Block of vacuum circuit-breaker, effectively can reduce the temperature of lower copper Connection Block, to such an extent as to reduce the temperature of whole vacuum circuit-breaker, thus improve the reliability of hollow circuit breaker really.
Be to be understood that, although this specification describes according to each execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, technical scheme in each execution mode also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
A series of detailed description listed is above only illustrating for feasibility execution mode of the present utility model; they are also not used to limit protection range of the present utility model; allly do not depart from the utility model skill equivalent embodiments of doing of spirit or change; as the combination of feature, segmentation or repetition, all should be included within protection range of the present utility model.
