Abstract
Disclosed is a totally enclosed outdoor high voltage fuse, comprising a melt part having self-arc-extinguishing capability, an organic composite insulator wrapping the metal part, and an upper lead assembly and a lower lead assembly which respectively insert into the organic composite insulator and are conducted to the melt part, wherein the melt part is internally provided with an elastic apparatus. In the totally enclosed outdoor high voltage fuse, all the live-line parts are completely enclosed in the insulating material. When the melt part is fused, the elastic apparatus in the melt part starts to move, with the self-arc-extinguishing capability allowing the melt part to rapidly cut off the loop. Meanwhile, the elastic apparatus also drives a red soft end cap at the bottom of the fuse to shed off, thereby displaying the motion state of the fuse. The totally enclosed outdoor high voltage fuse of the utility model can switch on/off the heavy/ light current having various faults, with excellent contact performance, anti-dirty performance, and insulating performance, thereby effectively preventing the faults of accidental short circuits, featuring convenient installation and reliable performance, and being worthwhile for being promoted.
Description
Technical field
The utility model relates to the high-voltage electrical apparatus field, relates in particular to a kind of totally enclosed type outdoor high-voltage fuse.
Background technology
The outdoor type fuse is one of maximum power product of distribution system use amount as the overload of distribution line and power transformer and the usefulness of short-circuit protection.
Because all electrified bodies of most existing outdoor high-voltage fuse all expose in atmosphere, caused thus accidental short circuit fault happens occasionally.In recent years, China adopts expensive imported product in large quantities, though on certain degree, improved reliability of products, the generation that does not fundamentally solve the accidental short circuit fault.Even adopted insulation protective hood; Its effect is equivalent to drape over one's shoulders one deck " coat " to fuse, because the loose and manner of protective cover causes poorly sealed; Sleety weather forms ponding and accumulated snow; Not only do not play good protective action, worsened the service condition of fuse on the contrary, reduced safety in utilization.
The overhead transmission line of China city, town's electrical network has used insulated conductor in large area, and the exposed fuse of electrified body becomes a weak spot.So, study a kind of totally enclosed outdoor fuse, for comprehensive power supply reliability that improves China's power distribution network, have crucial meaning.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art and a kind of totally enclosed type outdoor high-voltage fuse is provided; It is completely enclosed within all live parts in the insulator; Can cut-off the big or small electric current of various faults; Contact performance is good, and the dirty and good insulation preformance of resistant has effectively been avoided the generation of accidental short circuit fault.
The technical scheme that realizes above-mentioned purpose is:
A kind of totally enclosed type outdoor high-voltage fuse; Comprise that one has from the melt parts of arc extinguishing ability and the organic composite insulator of these melt parts of parcel; And insert respectively said organic composite insulator and with said melt parts join the upper conductor assembly and the lower wire assembly of conducting, wherein:
Said organic composite insulator adopts to have insulated tube and the silicon rubber that high-strength polyimide fiber processes and is composited;
Said upper conductor assembly and lower wire assembly skin separately all adopt insulating material.
Above-mentioned totally enclosed type outdoor high-voltage fuse, wherein, the inside of said melt parts is provided with a catapult-launching gear.
Above-mentioned totally enclosed type outdoor high-voltage fuse, wherein, said upper conductor assembly inserts the front end of said organic composite insulator, and the lead of this upper conductor component internal is connected with the front end of said melt parts and conducting; Said lower wire assembly inserts the rear side end of said organic composite insulator, and the lead of this lower wire component internal is connected with the rear end of said melt parts and conducting.
The beneficial effect of the utility model is: the utility model is completely enclosed within all live parts (comprising the melt parts) in the insulating material, when fusing takes place in melt, and through the triggering catapult-launching gear, line disconnection, and make this fuse have tangible breakpoint identification; The utility model can cut-off the big or small electric current of various faults, and contact performance is good, and the dirty and good insulation preformance of resistant has effectively been avoided the generation of short trouble; Simultaneously, the utility model is made simple, and is easy for installation, and dependable performance has excellent popularization and is worth.
Description of drawings
Fig. 1 is the section of structure of the utility model.
Embodiment
To combine accompanying drawing that the utility model is described further below.
See also Fig. 1; A kind of totally enclosed type outdoor high-voltage fuse of the utility model; Comprise that one has from the organic composite insulator 2 of the melt parts of arc extinguishing function 3 with these melt parts 3 of parcel, and insert respectively organic composite insulator 2 and with melt parts 3 join the upper conductor assembly 1 and the lower wire assembly 4 of conducting.
Organic composite insulator 2 adopts to have insulated tube and the silicon rubber that high-strength polyimide fiber processes and is composited; Upper conductor assembly 1 all adopts insulating material with lower wire assembly 4 skin separately, and upper conductor assembly 1 inserts the front end of insulator 2, and this upper conductor assembly 1 inner lead is connected with the front end of melt parts 3 and conducting; Lower wire assembly 4 inserts the rear side end of insulator 2, and these lower wire assembly 4 inner leads are connected with the rear end of melt parts 3 and conducting.
The inside of melt parts 3 is provided with a catapult-launching gear 31.
Red soft end cap 5 can show the operate condition of fuse.
The operation principle of the utility model: the electric wire of both sides is introduced upper conductor assembly 1 and lower wire assembly 4 respectively; Because the outer layer insulation of upper conductor assembly 1 and lower wire assembly 4, the termination of the electric wire of then introducing does not have electrified body to be exposed to the outside in the inside of upper conductor assembly 1 and lower wire assembly 4; All live parts (comprising melt parts 3) are completely enclosed within the insulating material; When fusing takes place in melt, through triggering catapult-launching gear 31, melt parts 3 can be from the arc extinguishing ability with the loop fast shut-off.Simultaneously, the red soft end cap 5 that catapult-launching gear 31 also will drive the fuse bottom comes off, and to show the operate condition of fuse, makes this fuse have tangible breakpoint identification.
In sum, the utility model can cut-off the big or small electric current of various faults, and contact performance is good, and the dirty and good insulation preformance of resistant has effectively been avoided the generation of short trouble; Simultaneously, it makes simple, and is easy for installation, and dependable performance has excellent popularization and is worth.
Above embodiment only supplies to explain the usefulness of the utility model; But not to the restriction of the utility model; The technical staff in relevant technologies field under the situation of spirit that does not break away from the utility model and scope, can also make various conversion or modification; Therefore all technical schemes that are equal to also should belong to the category of the utility model, should be limited each claim.
