Description
Technical field
The utility model relates to a kind of fuse, and more particularly, it relates to a kind of fuse switch.
Background technology
Fuse switch is made up of following several parts, include post insulator, cartridge fuse, post insulator be fixed with respectively up and down top electrode connecting plate and bottom electrode connecting plate, above top electrode connecting plate, fix successively static contact and rain cover, between static contact and rain cover, be provided with spring, on bottom electrode connecting plate, be fixed with support and with the gudgeon of support assorted and with little spring send out plate, in cartridge fuse, be provided with fuse, the pressure releasing cap that fuse one end arranges by cartridge fuse upper end compresses, the fuse other end on the other side is fixed on bottom electrode connecting plate through sending out plate, fuse is in tension.
In existing product, in the time that fuse switch is in running order, static contact compresses pressure releasing cap under the effect of spring, pressure releasing cap that fuse one end arranges by cartridge fuse upper end compresses, and the other end makes cartridge fuse in normal "on" position through sending out a plate and being fixed on bottom electrode connecting plate in tension.In the time that electric power system is broken down, fault current is by fuse quick-break, after fuse failure, send out plate resets rapidly under the effect of little spring, cartridge fuse and gudgeon lose tension force and under turn over, cartridge fuse is subject to the pressure of static contact upper spring, adds that dead weight effect falls rapidly.In the time that cartridge fuse is installed, the length of fusion tube will be selected moderate, so as not to be in operation there is the misoperation fallen voluntarily or melt fusing after fusion tube can not fall in time, but cartridge fuse length in reality can not regulate long or too short, so go to go again to buy one, time-consuming effort again.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide: a kind of fuse switch, the cartridge fuse length of this fuse switch can regulate, convenient simply again, when noting be used in installation, always changes.
For achieving the above object, the utility model provides following technical scheme: a kind of fuse switch, comprise post insulator, lower moving contact, cartridge fuse, be arranged on top electrode connecting plate and the bottom electrode connecting plate of post insulator two ends for wiring, the static contact being electrically connected with top electrode connecting plate, be arranged on the pressure releasing cap that cartridge fuse upper end is electrically connected with static contact, be arranged on the fuse in cartridge fuse, the pressure releasing cap that described fuse one end arranges by cartridge fuse upper end compresses, the other end on the other side is fixed on bottom electrode connecting plate through the plate of sending out with little spring, described cartridge fuse comprises inner and outer tubes, described outer tube sleeve is established on inner pipe, internal thread on described outer tube wall, described outer wall of inner tube is provided with corresponding external screw thread, on the inwall of described outer tube with respect to inner tube one end, be embedded with the constant force spring that orders about the inversely winding type that inner tube moves outwardly.
The utility model is further set to: described outer wall of inner tube is provided with graduation mark.
The utility model is further set to: on the outer wall of described outer tube with respect to inner tube one end, be rotary with screw, described outer tube is provided with corresponding screwed hole, and described screwed hole runs through outer tube.
The utility model is further set to: described constant force spring comprises fixed head and roll bending, and described roll bending one end is fixed on fixed head.
By adopting technique scheme, installing in the process of cartridge fuse, if think that cartridge fuse length is not moderate, can turn inner tube make cartridge fuse elongated or shorten, so just do not spend and changed again another one cartridge fuse, facilitate simply again; On the inwall of outer tube with respect to inner tube one end, be embedded with the constant force spring that orders about the inversely winding type that inner tube moves outwardly, so just can make inner and outer tubes more firmly link together, thus prevent inner and outer tubes relatively rotate change cartridge fuse length cause being in operation there is the misoperation fallen voluntarily or melt fusing after fusion tube can not fall in time; On the outer wall of outer tube with respect to inner tube one end, be rotary with screw, further make inner and outer tubes more firmly link together, outer wall of inner tube is provided with graduation mark, when cartridge fuse be adjusted to moderate after, can conveniently remember this value, in the time changing next time, cartridge fuse just need not have been debugged again.

Embodiment
Referring to figs. 1 through Fig. 5, the utility model fuse switch embodiment is described further.
A kind of fuse switch, comprise post insulator 9, lower moving contact 8, cartridge fuse 4, be arranged on top electrode connecting plate 1 and the bottom electrode connecting plate 7 of post insulator 9 two ends for wiring, the static contact 10 being electrically connected with top electrode connecting plate 1, be arranged on the pressure releasing cap 11 that cartridge fuse 4 upper ends are electrically connected with static contact 10, be arranged on the fuse 3 in cartridge fuse 4, the pressure releasing cap 11 that described fuse 3 one end arrange by cartridge fuse 4 upper ends compresses, the other end on the other side is fixed on bottom electrode connecting plate 7 through the plate of sending out with little spring, it is characterized in that: described cartridge fuse 4 comprises inner tube 42 and outer tube 41, described outer tube 41 is set in inner tube 42, internal thread on described outer tube 41 inwalls, described inner tube 42 outer walls are provided with corresponding external screw thread, on the inwall of described outer tube 41 with respect to inner tube 42 one end, be embedded with the constant force spring 5 that orders about the inversely winding type that inner tube 42 moves outwardly.
