When after high-tension fuse action, the striker of striker will outwards eject and promote the release lever of fuse switch, makes high-tension fuse realize rotational motion and completes and fall action.When high-tension fuse is after a disjunction is used, rotation upper end cap, take off upper end cover plate, because the seven-star spinous process of the seventh cervical vertebra frame other end is provided with spring, so in the time taking off upper end cover plate, spring can be released firming body laterally because of reinstatement, is convenient to take out firming body and changes, and improves useful life and the resource utilization of equipment.
Further, described seven-star spinous process of the seventh cervical vertebra frame is high-purity type aluminium oxide ceramics seven-star spinous process of the seventh cervical vertebra frame, has extraordinary conductibility, mechanical strength and heat-resisting quantity, improves the overall performance of equipment.
Further, described fuse is fine copper fuse, replaces expensive noble silver, reduces production costs significantly.
The invention has the beneficial effects as follows: be convenient for changing its inner firming body, improve useful life and the resource utilization of equipment, further, improve the performance of integral device.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of high-tension fuse of the present invention;
The mark implication of accompanying drawing is as follows:
1: seven-star spinous process of the seventh cervical vertebra frame; 2: fine copper fuse; 3: quartz sand layer; 4: fusing organ pipe; 5: lower end cover plate; 6: spring; 7: lower endcaps; 8: upper end cap; 9: striker; 10: copper sheet sealing; 11: upper end cover plate; 12: metal cap; 13: brace.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, technical solution of the present invention is described in further detail, can be implemented so that those skilled in the art can better understand the present invention also, but illustrated embodiment is not as a limitation of the invention.
As shown in Figure 1, a kind of high-tension fuse, comprises fusing organ pipe 4 and is arranged on the firming body in fusing organ pipe 4 with removably.Wherein said firming body comprises solid black part in seven-star spinous process of the seventh cervical vertebra frame 1, fuse and quartz sand layer 3(figure), on described seven-star spinous process of the seventh cervical vertebra frame 1, be wound with fuse, the head of described fuse and afterbody are fixed on the metal cap 12 of seven-star spinous process of the seventh cervical vertebra frame 1 one end (being the right-hand member in Fig. 1), such as the head of fuse and afterbody point being welded on metal cap 12, so that electric current is outwards drawn by metal cap 12.
Seven-star spinous process of the seventh cervical vertebra frame 1 can be ceramic seven-star spinous process of the seventh cervical vertebra frame 1, and such as high-purity type aluminium oxide ceramics seven-star spinous process of the seventh cervical vertebra frame 1, aluminium oxide ceramics is divided into two kinds of high-purity type and plain editions, and wherein high-purity type aluminium oxide ceramics is Al
2o
3the ceramic material of content more than 99.9%.Preferred fuse is fine copper fuse 2, replaces expensive noble silver, reduces production costs significantly.Metal cap 12 centers are provided with striker 9, and metal cap 12 both sides are provided with brace 13, and described seven-star spinous process of the seventh cervical vertebra frame 1 outside is solidified with quartz sand layer 3.Seven-star spinous process of the seventh cervical vertebra frame 1, fuse and quartz sand layer 3 are solidified into one, can insert or extract fusing organ pipe 4.
