Abstract
The utility model relates to a horizontal drop out fuse, including insulating knob insulator, cartridge fuse and both ends binding post, the fuse setting is in the cartridge fuse, insulating knob insulator and cartridge fuse level are placed, and the head end chuck is connected to the one end of cartridge fuse, and the other end of cartridge fuse is connected with the one end of electrically conductive arm, and the other end of electrically conductive arm links to each other with afterbody suspension hooks, be equipped with contact and reed between electrically conductive arm and the afterbody suspension hooks. Because the cartridge fuse is the horizontality and puts, the pull rod operating angle is very good, personnel's fuse that conveniently pulls open, closes. The utility model discloses the visual inspection of equipment because observation angle well also is convenient for.
Description
Technical field
The utility model relates to a kind of fuse, refers in particular to a kind of horizontal fuse switch.
Background technology
As shown in Figure 1, fuse switch of the prior art generally installs the Zhi Tie of fuse in insulation porcelain knob top and bottom, by the pressing plate of the touch spring of upper end, hanged hook and lower end and shackle, cartridge fuse is fixed on fuse, when there is fuse failure, lower end blocking mechanism will get loose, and be subject to gravity effect, and cartridge fuse upper end will be separated from upper hanged hook, whole cartridge fuse is by centered by following end hook ring, and circular arc swings and is suspended on fuse.Because angle of inclination a during design and installation is 20-30 degree, the installation site of fuse is very high again, when therefore librarian use operation pull bar carries out power transmission operation, very little with the work angle of cartridge fuse, operate when closing the upper contact head of cartridge fuse and require great effort very much, once successfully possibility is very little.Because angle of inclination is little, there is vision dead zone, operating personnel are not easy upper contact head to aim at intermediate plate, and tour personnel also require great effort to contact situation visual inspection very much.
Utility model content
The utility model, for above-mentioned problems of the prior art, provides a kind of horizontal fuse switch, solves in prior art and there is vision dead zone, unhandy problem.
The utility model solves the technical scheme that its technical problem adopts:
Fuse comprises insulation porcelain knob, cartridge fuse and two ends binding post, and fuse is arranged in cartridge fuse; Insulation porcelain knob and cartridge fuse horizontal positioned, one end of cartridge fuse connects head end chuck, and the other end of cartridge fuse is connected with one end of conductive arm, and the other end of conductive arm is connected with rear suspension hook; Contact and reed is provided with between conductive arm and rear suspension hook.
Described conductive arm is L shape, and L shape conductive arm is connected with fixed head by movable rotation-shaft, is provided with spring between fixed head and L shape conductive arm.
Described fuse is connected with L shape conductive arm by set bolt.
Described L shape conductive arm and the below of cartridge fuse are provided with operation ring.
Described insulation porcelain knob is provided with the connecting plate of connection device framework.
The utility model has the advantages of as follows:
Put because cartridge fuse is the level of state, pull bar work angle is very good, and personnel conveniently pull open, close fuse.Because viewing angle is well also convenient to the visual examination of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art fuse switch.
Fig. 2 is the structural representation of the horizontal fuse switch of the utility model.
In figure, 1, insulation porcelain knob, 2, cartridge fuse, 3, binding post, 4, fuse, 5, head end chuck, 6, rear suspension hook, 7, conductive arm, 8, contact, 9, reed, 10, movable rotation-shaft, 11, fixed head, 12, spring, 13, set bolt, 14, operation ring, 15, connecting plate.
Embodiment
Further illustrate this use is novel below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 2, fuse comprises insulation porcelain knob 1, cartridge fuse 2 and two ends binding post 3, and fuse 4 is arranged in cartridge fuse 2; Insulation porcelain knob is provided with the connecting plate 15 of connection device framework, insulation porcelain knob 1 and cartridge fuse 2 horizontal positioned, one end of cartridge fuse 2 connects head end chuck 5, and the other end of cartridge fuse 2 is connected with one end of conductive arm 7, and the other end of conductive arm 7 is connected with rear suspension hook 6; L shape contact 8 and reed 9 is provided with between conductive arm 7 and rear suspension hook 6.
Described conductive arm is L shape, and L shape conductive arm is connected with fixed head 11 by movable rotation-shaft 10, is provided with spring 12 between fixed head 11 and L shape conductive arm; Described fuse 4 is connected with L shape conductive arm 7 by set bolt 13; Described L shape conductive arm and the below of cartridge fuse are provided with semicircle operation ring 14.
When cartridge fuse Internal fuse installs tension, spring contraction, L shape contact withstands cartridge fuse, and cartridge fuse is the level of state.First be hung in hook by afterbody with pull bar, then sandwich in head end chuck by head end cartridge fuse, the contact of afterbody is with to be connected switch jaw contact good, and whole galvanic circle completes.Put because cartridge fuse is the level of state, pull bar work angle is very good, and personnel conveniently pull open, close fuse.Because viewing angle is well also convenient to the visual examination of equipment.During normal condition, electric current is through mains side binding post, flows through fuse, L shape conductive arm, tail contacts and reed, safety clip completes whole loop.When under accident condition during fuse failure, lever mechanical balance is broken, spring release potential energy pushes L shape conductive arm open, power circuit interrupts and head end contact is departed from from chuck and is vertically hung on hanged hook after the landing of whole cartridge fuse mechanism, and operating personnel can take off with pull bar and carry out the operation of replacing fuse.
Protection range of the present utility model is as the criterion with claims, does not limit by specific embodiment.
