Abstract
The utility model provides a fully-insulated expulsion fuse, which comprises a porcelain sleeve. A fuse tube is arranged in the porcelain sleeve. The upper and lower ends of the fuse tube are connected with an electrode respectively. An upper connecting line is led out of the electrode connected with the upper end of the fuse tube through an upper binding post arranged at the upper end portion of the porcelain sleeve. A lower connecting line is led out of the electrode connected with the lower end of the fuse tube through a lower binding post transversely arranged at the lower end portion of the porcelain sleeve or on the lower side wall of the porcelain sleeve. The bottom of the porcelain sleeve is at least provided with a dustproof sealing cover. The upper binding post is fixed onto the upper end portion of the porcelain sleeve through a nut-bolt connection structure. The fuse tube is arranged in the inner cavity of the porcelain sleeve at least through a fuse tube bracket and a spring. The included angle formed between the placement position of the fuse tube and a plumb line is in the form of a 15-30 degree camber angle. The lower binding post, for leading out the lower connecting line, is transversely arranged on the lower side wall of the porcelain sleeve. The middle section of the porcelain sleeve is transversely provided with a mounting hoop used for mounting the fuse onto a hardware. The fully-insulated expulsion fuse has the advantages of convenient operation, stable performance, reliable movement and the like.
Description
Technical field
The utility model relates to a kind of distribution line and distribution transformer primary side as protection and carry out equipment throwing, cut all insulation expulsion fuse of the use of operation, belonging to the protective switch of the short circuit technical field of distribution line and distribution transformer.
Background technology
In power distribution network, more than 98% user uses fuse switch at present, and the type fuse exists insufficiency, and protective value is poor; temperature rise; break performance is low, electric and Mechanical Contact face is little, antifouling; antitheft; anti-fault-free comes off, and anti-operation is dangerous, combined floodgate success rate; circuit operation ratio, the problem of the aspects such as arc extinguishing.Even also often there is substandard product selecting of fuse; certain customers even replace fuse with copper wire, aluminum steel; in addition the own inherent characteristic of fuse; fuse can not normally be protected and coordinate with prime switchgear; while often occurring because of user side fault, expand the accident of power failure range, meanwhile, when a line failure; investigation fail operation is also very difficult, is unfavorable for the operational management of power distribution network.Improve the security reliability of power supply although can select automatic circuit to substitute fuse switch with the important user of load greatly to power consumption, most of user is difficult to accept this scheme because automatic circuit is expensive.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of easy to operate, stable performance, all insulation expulsion fuse of reliable in action.
The purpose of this utility model completes by following technical solution, it includes an insulator, the cartridge fuse that upper and lower side is connected with respectively electrode is installed in insulator, the upper connecting terminal that described upper end electrode arranges by insulator upper end leads to upper connecting line, lower end electrode leads to lower connecting line by the lower connecting terminal of horizontally set on insulator bottom or lower sides, and described insulator bottom at least disposes the seal cover of a dustproof use.
Described upper connecting terminal adopts nut bolt syndeton to be fixed on insulator upper end; Described cartridge fuse is at least placed in insulator inner chamber by fusion tube support and spring, and the angle of described cartridge fuse position and the plumb line settled is that flare 15-30 is spent.
On described insulator lower sides, be horizontally arranged with the lower connecting terminal of drawing lower connecting line; Described insulator stage casing is horizontally arranged with one for fuse being installed to the installation anchor ear on gold utensil.
The utlity model has the features such as easy to operate, stable performance, reliable in action.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, the utility model includes an insulator 1 that can play fine insulation effect, the cartridge fuse 2 that upper and lower side is connected with respectively electrode is installed in insulator 1, the upper connecting terminal 4 that described upper end electrode 3 arranges by insulator 1 upper end leads to upper connecting line 5, lower end electrode 6 leads to lower connecting line 8 by the lower connecting terminal 7 of horizontally set on insulator 1 bottom or lower sides, and described insulator 1 bottom at least disposes the seal cover 9 of a dustproof use.
Shown in figure, described upper connecting terminal 4 adopts nut bolt syndeton 10 to be fixed on insulator 1 upper end, in use procedure, user can turn Insulation spanner with a hand-screw, another hand interts by insulating tool or pulls out and unload band electrolytic copper lead-in wire (connecting line), possesses live line working and disconnects lead-in wire condition; Described cartridge fuse 2 is at least placed in insulator 1 inner chamber by fusion tube support and spring 10, and the standard installation pulling force that described fusion tube stand spring 10 awards cartridge fuse 2 is 50N, and this power is not closed a floodgate by fusible link and done the impact of power size; The position that described cartridge fuse 2 is settled and the angle of plumb line are flare 15-30 degree, and it can guarantee that, after fuse failure, cartridge fuse 2 reliably falls.
On described insulator 1 lower sides, be horizontally arranged with the lower connecting terminal 7 of drawing lower connecting line 8; Described insulator 1 stage casing is horizontally arranged with one for fuse being installed to the installation anchor ear 11 on gold utensil.
Claims (3)
