Abstract
The utility model discloses a fuse carrier bracket, which comprises a fixed installing part which is used for fixedly installing the fuse carrier bracket per se, two riveting parts which are used for riveting contacts and are arranged at the right side end and the left side end of the fixed installing part, and two cantilever hooks which are downward and obliquely extended from the ends of the two riveting parts. A shaft groove with an upward opening is arranged on each cantilever hook. A guide plate which protrudes towards a direction close to the other cantilever hook is arranged at the bottom part of each cantilever hook. The utility model has the advantages that not only the fuse tube is prevented from directly colliding with the cantilever hooks but also the trunnion and the fuse tube can be guided to rotate.
Description
Technical field
The utility model belongs to the fuse technical field, is specifically related to a kind of fusing carrier support.
Background technology
Fuse is a kind of protection equipment that the protection electric equipment was avoided the short circuit infringement.Its operation principle is when line short or overload, melt in the fuse fusing carrier is dissolved formation electric arc, and at the drop-down long arc of the effect of elastic body, high arc temperature makes the inner aerogenesis medium of fusing carrier resolve into gas simultaneously, in the fusing carrier pipe, set up very high pressure, free metal gas bleed pipe is made arc extinction outward, thereby cut-off short circuit current, fusing carrier falls under the effect of deadweight simultaneously, forms a visible isolation fracture.The history in existing more than 50 year of the development of China's fuse switch, in early days based on imitative Soviet Union product, the mid-1970s has improved many products from grinding, because of product material and design level are limit, manufacture level improves little, the later stage eighties increases along with introducing with exchange of technology, and product has had tremendous development, has possessed world standard substantially.Because the short circuit interruption ability of fuse improves constantly and good and economic, now accepted and be extensive use of by vast power consumer, nearly 2,000,000 of annual demand.
Fuse switch is one of the most frequently used electrical device of distribution system, also is the power product of distribution system use amount maximum.But because its unit value is lower, structure is simple relatively, all is some small-sized manufacturing firm processings basically in China, and product exists shortcomings such as break performance instability, through-current capability is low, the life-span is short, and is not solved well recent decades.
At present, no matter be domestic or external product, the fusing carrier support that is used for fuse switch, gudgeon only is suspended in the axial trough of cantilever hooks of fusing carrier support by a rotating shaft, because axial trough is an opening groove that opening makes progress, rotating shaft is slided in axial trough easily, so when carrying out breaking-closing operating, because dynamics is bigger, the cartridge fuse that links to each other with gudgeon often strikes on the cantilever hooks of fusing carrier support, cause it that deformation takes place, and then gudgeon and the stuck contingency in the fusing carrier support of cartridge fuse take place.
The utility model content
The purpose of this utility model provides a kind of fusing carrier support with guiding mechanism, and this fusing carrier support can prevent that cartridge fuse from directly striking on the cantilever hooks, bootable again gudgeon and cartridge fuse rotation.
The technical scheme that realizes the utility model purpose is: a kind of fusing carrier support comprises the fixed installation portion that self is installed of being used for fixing, is arranged on two caulking parts that are used for riveting dress contact of described fixed installation portion left and right sides end, from two cantilever hooks of the terminal downward-sloping stretching, extension of described two caulking parts; Described each cantilever hooks is provided with the axial trough that opening makes progress; It is characterized in that: the bottom of described each cantilever hooks is provided with the guide plate that protrudes towards near another cantilever hooks direction.
The outer surface of fixed installation portion, caulking part and the cantilever hooks of described fusing carrier support is provided with the reinforcement that protrudes towards lateral direction.
On described caulking part, described reinforcement is along the trough rim setting of described axial trough.
Described fixed installation portion is provided with the fixed installation hole, and described each caulking part is provided with two riveted holes.
The utlity model has positive effect: in the utility model, the bottom of described each cantilever hooks is provided with the guide plate that protrudes towards near another cantilever hooks direction, under the guide effect of these two guide plates, this fusing carrier support can prevent that cartridge fuse from directly striking on the cantilever hooks, bootable again gudgeon and cartridge fuse rotation.
In the utility model, the outer surface of fixed installation portion, caulking part and the cantilever hooks of described fusing carrier support is provided with the reinforcement that protrudes towards lateral direction; This structure can guarantee its useful life and functional reliability keeping cheaply increasing the intensity of cantilever hooks and suspension arm under the prerequisite.
