Description
Technical field
Basis is practical relates to a kind of device for installing fuse, particularly relates to the detachable holder of a kind of 35KV fusing organ pipe, its fast changeable fuse tube.
Background technology
At present, 35kV fuse is made up of fuse tube, insulator, clamp flange, solid core post insulator and wiring end cap etc.By the method press-fited, the wiring end cap at two ends and fuse tube are fixed in insulator, then with clamp flange, insulator is fixed on solid core post insulator, fuse tube adopts the higher raw material of silicon oxide-containing to make arc-extinguishing medium, the metal wire of application minor diameter does fuse, and when overload current or short circuit current are by fuse tube, fuse fuses immediately, electric arc occurs in several narrow slits in parallel, metallic vapour in electric arc infiltrates in quartz sand, is strongly gone to dissociate, rapidly arc extinction.So this fuse performance is good, cut-offs capacity large.But existing fuse tube adopts clamp flange to fix, and fuse is arranged on open air, affected by environment, fastening bolt corrosion, change fuse tube dismounting difficulty and take longer, have impact on timely power supply.
Domestic more existing open source literature about fuse holder report:
Such as: [patent No.] 201220068584.2, [title] fuse mount pad, [day for announcing] 2012.09.19, [summary] mainly solves the problem that the inconvenient and U-shaped clamping steel wire fatiguability of existing fuse mount pad installation and removal fuse makes clamping force reduce.Comprise articulated elements, two insulated supports and two intermediate plate compositions, intermediate plate is fixed on insulated support, intermediate plate is hinged with the U-shaped clamping steel wire of integral structure, the opening part both sides of intermediate plate extend outward fin, on fin, one end of corresponding U-shaped clamping steel wire is provided with inclined-plane, the outer ledge of fin is provided with semicircular arc locating groove, at least one circle circle of bottom coiled coil of U-shaped clamping steel wire.This fuse mount pad changes the shape of U-shaped clamping steel wire, has the advantages that installation and removal fuse convenience, U-shaped clamping steel wire indefatigability and clamping force are large.Although this mount pad energy quick-replaceable fuse tube, the crystallized ability meeting of mount pad to fuse tube be had a greatly reduced quality because clamping structure of steel wire is tired, the fixed effect that very difficult maintenance is good; Secondly, because mount pad is taked to clamp fixing form, process fuse tube being compressed into clamping steel wire needs comparatively great strength, once dynamics is held bad, then can cause the damage of new fuse tube.
Therefore, existing fusing organ pipe holder technology is still immature, and be mainly reflected in fuse tube dismounting difficulty and fixed effect not lastingly, needs will make further improvement.
Summary of the invention
The purpose of this utility model solves the problems such as fuse tube dismounting difficulty that at present fusing organ pipe holder exists, fixed effect be not lasting, provides a kind of easy accessibility, replace tubes is rapid, fixed effect is lasting detachable holder.
The detachable holder of 35KV fusing organ pipe of the present utility model, comprise base, described base is provided with fuse tube mounting groove, and be provided with the removable cover for clamping fuse tube above mounting groove, removable cover surrounds the retainer plate of fuse tube together with mounting groove; Removable cover two ends are connected with the lug boss of locking mechanism with mounting groove both sides respectively by articulated elements.
Further illustrate as to of the present utility model, described base is trapezoidal, is provided with fixing hole below base; Base passes through on fixing hole insulated support mounted externally.
Further illustrate as to of the present utility model, described articulated elements is a hinge connecting removable cover and lug boss respectively; Described locking mechanism comprises bolt and hold-down nut, and described nut is fixed on another lug boss of mounting groove; Articulated elements is provided with screwed hole, and when installing fuse tube, articulated elements is tightened fixing through screwed hole by bolt.
Further illustrate as to of the present utility model, described bolt is butterfly bolt; Be welded on through articulated elements on the left of removable cover on the lug boss on the mounting groove left side; Described screwed hole is arranged on the right side of removable cover, and screwed hole diameter is 10-14mm; Lug boss on the right of described mounting groove is provided with the nut corresponding with screwed hole and installs, and this nut installing hole is for installing hold-down nut.Adjustment butterfly bolt can realize removable cover to the compression of fuse tube or release.
Further illustrate as to of the present utility model, described removable cover, base, articulated elements, bolt, nut all adopt stainless steel to make; Described removable cover thickness is 2-4mm.
Further illustrate as to of the present utility model, described removable cover is curved, and Open Side Down, the curved opening upwards of mounting groove, and removable cover and mounting groove can be spliced into the retainer plate mated with fuse tube radius just.
Further illustrate as to of the present utility model, described removable cover is of a size of: long 140mm, span 40mm, high 42mm; Described base is of a size of: upper length of side 150mm, lower length of side 165mm, wide 40mm, high 50mm; Described bolt is of a size of: long 35mm, diameter 10mm; Described hold-down nut is of a size of: high 10mm, wide 20mm; Described articulated elements is of a size of: long 10mm, wide 40mm, high 2mm.
The detachable holder of 35KV fusing organ pipe of the present utility model solves the shortcoming and defect of prior art, compared with prior art has following progress:
1, surrounded the retainer plate of fuse tube together with mounting groove by removable cover, such mounting structure mounting or dismounting are more convenient: because removable cover can stir, when safeguarding, unlocked mechanism, opens removable cover, can take out the fuse tube needing to change; When fuse tube is installed, as long as cover and lock removable cover, fuse tube can be fixed.Therefore holder of the present utility model can be changed fast when fuse tube damages, and restores electricity in time.
2, the tightness of removable cover is by locking mechanism controls, and the main working parts of locking mechanism is bolt and hold-down nut, and the fixed effect of bolt is more far better than the U-shaped clamping steel wire of prior art; More what deserves to be explained is, even if having a little distortion along with the prolongation removable cover of useful life, as long as add king-bolt screw degree, fuse tube firmly can be fixed equally, therefore the fixed effect of the utility model holder is better.
3, replace tubes process can not cause the damage of new fuse tube, because the utility model adopts the mode of renovating replace tubes, installation process does not need firmly to extrude fuse tube, reduces the impaired risk of fuse tube.
