Abstract
The utility model relates to a lightning-protection fuse used for a transformer, pertaining to a transformer fusing device with lightning protection. The utility model mainly solves the technical difficulties of the prior fusing device such as time and labor consuming, inconvenient installation and maintenance, etc. The technical proposal of the utility model is that the lightning-protection fuse includes an upper static contact, a pressure releasing cap, an upper active contact, a fuse tube, a lower active contact, a lower support, a ceramic bottle and a mounting plate; wherein, the fuse also includes a lightning arrester ; the lightning arrester is arranged in the upper half part of the inner cavity of the ceramic bottle and fixed by epoxide resin; the incoming line of the lightning arrester is connected with the upper side connecting line of the fuse; the grounding line of the lightning arrester is led out of the middle part of the ceramic bottle, connected with the mounting plate and reliably grounded. The fusing device with lightning protection provided by the utility model has the advantages of expenditure saving, convenient installation and maintenance, safety, reliability, etc.
Description
Technical field
The utility model relates to the lightning-arrest fuse of a kind of transformer, and it belongs to a kind of transformer device for fusing with lightning protection function.
Background technology
At present, the device for fusing that transformer uses does not have lightning arrester, for pre-anti-lightning strike also the need connect lightning arrester between fuse and transformer, has so both made the transformer stand very in disorder, and installs that lightning arrester is also time-consuming takes a lot of work.Therefore, existing device for fusing exist time-consumingly take a lot of work, defective such as installation and maintenance inconvenience.
Summary of the invention
The purpose of this utility model be solve existing device for fusing exist time-consumingly take a lot of work, technological difficulties such as installation and maintenance inconvenience and provide a kind of and can reduce expenses, convenient for installation and maintenance and safe and reliable transformer is with lightning-arrest fuse.
The utility model for the technical scheme that solves above-mentioned technological difficulties and adopt is: transformer is with lightning-arrest fuse, it comprises one by upper static contact, pressure releasing cap, goes up the fuse that moving contact, fusion tube, lower moving contact, undersetting, porcelain vase and mounting panel constitute, wherein: it also comprises lightning arrester, lightning arrester is contained in the first half of porcelain vase inner chamber and fixes with epoxy resin, the inlet wire of lightning arrester links to each other with the wiring of fuse upside, and the earth connection of lightning arrester is drawn from the middle part of porcelain vase and is connected and reliable ground with mounting panel.
Described lightning arrester is any one in zinc oxide arrester, valve type arrester or the silica gel lightning arrester.
Because the utility model has adopted technique scheme, lightning arrester is contained in the porcelain vase of fuse, has saved the cross-arm that the installation lightning arrester is used, lead-in wire, screw etc., reduced fee of material, engineering costs such as installation fee, every the about cost saving 600-1000 of transformer unit.Make things convenient for installation, maintenance, the maintenance of fuse equipment, and improved the aesthetic measure of transformer stand greatly.Eliminate mistake and bumped the dangerous accident that the lightning arrester lead-in wire is taken place.Therefore, compare, the utlity model has advantage such as can reduce expenses, convenient for installation and maintenance and safe and reliable with background technology.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in drawings, the lightning-arrest fuse of transformer in the present embodiment, it comprises one by upper static contact 1, pressure releasing cap 2, last moving contact 3, fusion tube 4, lower moving contact 5, undersetting 6, the fuse that porcelain vase (skirt) 7 and mounting panel 8 constitute, wherein: it also comprises zinc oxide arrester 12, zinc oxide arrester 12 is contained in the first half of porcelain vase (skirt) 7 inner chambers and fixes with epoxy resin 11, the inlet wire 9 of zinc oxide arrester 12 links to each other with the wiring of fuse upside, and the earth connection 10 of zinc oxide arrester 12 is drawn from the middle part of porcelain vase (skirt) 7 and is connected and reliable ground with mounting panel 8.
Zinc oxide arrester in the foregoing description can also be in valve type arrester or the silica gel lightning arrester any one.
Claims (2)
