Abstract
The utility model relates to a compound AC high-voltage falling type fuse, composed of a porcelain vase, an upper and a lower hardware connected with both ends of the porcelain vase, and a fusion tube connected with the other side of the upper and the lower hardware. The utility model is characterized in that a hollow cavity is arranged in the porcelain vase. An arrester is arranged in the hollow cavity. The arrester is communicated with an installation supporting plate and the lower hardware. The utility model integrates the fuse and the arrester. The utility model causes the structure of a product to turn into compact and to be simplified. Not only the utility model causes the installation to obtain simplification, and the utility model saves materials, but also the utility model can cause the layout of the power transmission and distribution equipment to be more reasonable.
Description
The utility model relates to a kind of compound ac high-voltage fuse switch that is used for electrical power trans mission/distribution system, and it is the improvement to existing this fuse, makes it have fusing and lightning-arrest dual-use function.
The ac high-voltage fuse switch is a kind of power transmission and distribution element that has been widely used, and it is by porcelain vase, the upper and lower gold utensil that the porcelain vase two ends connect and constitute with the joining fusion tube of upper and lower gold utensil opposite side.In actual use, usually, ac high-voltage fuse switch palpus and Allocation of Lightning Arrester are used, because they are two separate elements, need install and fix respectively and connect with lead, like this, be to install cumbersome complexity on the one hand, mutual on the other hand lead connects not only wastes metal wire rod, and because the intersection laying of lead also often is easy to accidents caused.
Task of the present utility model is to avoid the weak point of above-mentioned existence and provides a kind of to collect fuse and lightning arrester is the compound ac high-voltage fuse switch of one, it can not only make the structure of product and installation procedure obtain simplifying, and can make the layout of equipment for power transmission and distribution more become reasonable.
Task of the present utility model is realized by following scheme: have a porcelain vase 7, the upper and lower side of porcelain vase is connected with gold utensil 12 and following gold utensil 11 respectively, upper and lower gold utensil and other end link by fusion tube 5, side at porcelain vase also is fixedly connected with mounting support plate 8, difference is to be provided with a cavity in porcelain vase 7, install a lightning arrester 10 in the cavity, an end and the mounting support plate 8 of lightning arrester link, and the other end then links with following gold utensil 11.
Press such scheme, the course of work of the present utility model is: under normal circumstances, carry electricity to communicate with equipment for power transmission and distribution through last gold utensil 12, fusion tube 5 and following gold utensil 11; when meeting thunderbolt; then lightning arrester 10 moment conducting through mounting support plate 8 and ground short circuit, plays the protection equipment for power transmission and distribution.Characteristics of the present utility model are under the situation that does not change fuse basic structure and profile, and lightning arrester is arranged at the inner chamber of fuse porcelain vase, make two mutually the discrete components that use of configuration be integrally combined, like this, unite two into one, make product structure become compact and simplify, simultaneously, when mounted, not only can reduce the workload of installation, reduce metal frame and mutual connecting conducting wire, save material, and can avoid the intersection of lead, make the layout of equipment for power transmission and distribution more reasonable.
Fig. 1 is the structure chart of an embodiment of the utility model.
An embodiment of the present utility model as shown in Figure 1, has a porcelain vase 7, the upper end of porcelain vase is fixedly connected with gold utensil 12, last gold utensil is provided with upper static contact 2 and last moving contact 1, the other end of last gold utensil and fusion tube 5 link, be equipped with fuse element 6 in the fusion tube, the other end of fusion tube 5 links with following gold utensil 11, in the middle and lower part of porcelain vase 7, be provided with a cavity, one lightning arrester 10 is installed in the cavity, lightning arrester can be zinc oxide arrester, inserts 9 is filled in the space around lightning arrester, in order to insulation with keep the intensity of porcelain vase, at a side transverse splicing of porcelain vase one mounting support plate 8 is arranged, the upper end that its inserted terminal enters porcelain vase cavity and lightning arrester 10 links, be connected with gold utensil 11 down in the lower end of porcelain vase 7, the lower end of following gold utensil and lightning arrester 10 links, and following gold utensil is provided with down fixed contact 4 and lower moving contact 3, and its movable contact head end and fusion tube 5 link.The also available synthetic material of porcelain vase of the present utility model is made.
