Abstract
The utility model relates to a high-voltage fuse with the excellent protective performance. For the prior high voltage fuse, the rain-proof effect is poor, the protective performance is low, so the product using performance is influenced, and the high-voltage fuse can solve the above problems. The high-voltage fuse includes a fuse tube, an insulating column, a rain and snow cover, and an acceleration frame. The rain and snow cover is arranged on one end of the insulating column, one end of the fuse tube is arranged in the rain and snow cover, and the other end is connected with the other end of the insulating column via the acceleration frame. The lower end of the rain and snow cover is provided with a wiring board. The wiring board is provided with a groove. The end of the rain and snow cover is arranged in the groove. The end of the wiring board is provided with a bent part which is bent from the end of the rain and snow cover to the upper end face of the rain and snow cover. Because the wiring board of the high-voltage fuse adopts the bent structure, the high-voltage fuse has the rain-proof effect in use, and the protection target is achieved, and consequently the product using performance is effectively improved.
Description
Technical field
The utility model relates to a kind of high-tension fuse, refers in particular to the good high-tension fuse of a kind of barrier propterty.
Background technology
High-tension fuse is mainly used in overload and the short-circuit protection of the electric equipments such as ultra-high-tension power transmission line, voltage transformer, voltage transformer, and when high-tension fuse met with overload or short circuit at circuit, the fuse failure of fusion tube played the effect of protective circuit.Existing high-tension fuse in use, because the right-hand member of sleet lid communicates with the external world, so when running into the rainy day, rainwater easily enters the sleet lid from the external world, thereby affect the contact point between terminal block and fusion tube, cause fusion tube, terminal block to damage, the useful life of having reduced product.
Summary of the invention
For shortcoming and the weak point that overcomes background technology, the utility model provides a kind of barrier propterty good high-tension fuse, solves existing high-tension fuse and has the weak effect that keeps off the rain, and causes barrier propterty low, thereby affects the technical problem of product serviceability.
The technical solution of the utility model is: the high-tension fuse that a kind of barrier propterty is good, comprise fusion tube, insulated column, sleet lid and accelerate frame, described sleet lid is installed on an end of insulated column, described fusion tube one end is installed in the sleet lid, the other end is connected with the other end of insulated column by accelerating frame, the lower end of described sleet lid is equipped with terminal block, described terminal block is provided with groove, the end of described sleet lid is placed in described groove, the end of described terminal block is provided with bending part, the upper surface bending that described bending part covers towards sleet from the end of sleet lid.
Described bending part and terminal block one are formed by connecting.
Described terminal block is made by copper product.
The sidepiece of described sleet lid is provided with catch, and described catch comprises the first catch and the second catch that one connects, described the second catch be positioned at the fusion tube outside and with respect to the lower surface of the first catch to downward-extension.
The utlity model has following beneficial effect: adopt the structure of bending due to the terminal block of this high-tension fuse, can play the effect of keeping off the rain in use, play the purpose of protection, thereby effectively raise the serviceability of product.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure, insulated column 1, fusion tube 2, sleet lid 3, the first catch 31, the second catch 32 accelerate frame 4, terminal block 5, bending part 6.
Embodiment
The below is described further embodiment of the present utility model for accompanying drawing:
shown in figure, the high-tension fuse that a kind of barrier propterty is good, comprise insulated column 1, fusion tube 2, sleet lid 3 and acceleration frame 4, described sleet lid 3 is installed on an end of insulated column 1, described fusion tube 2 one ends are installed in sleet lid 3, the other end is connected with the other end of insulated column 1 by accelerating frame 4, the lower end of described sleet lid 3 is equipped with terminal block 5, described terminal block 5 is provided with groove, the end of described sleet lid is placed in described groove, the end of described terminal block 5 is provided with bending part 6, described bending part 6 covers 3 upper surface bending towards sleet from the end of sleet lid 3.According to such scheme, adopt the structure of bending due to the terminal block of this high-tension fuse, can play the effect of keeping off the rain in use, play the purpose of protection, thereby effectively raise the serviceability of product.
In the utility model, described bending part 6 is formed by connecting with terminal block 5 one.Because this bending part and connecting plate are that one processes, easy to process, terminal block 5 integral body are made by copper product, conduct electricity very well.
In the utility model, the sidepiece of described sleet lid 3 is provided with catch, and described catch comprises the first catch 31 and the second catch 32 that one connects, described the second catch 32 be positioned at fusion tube 2 outsides and with respect to the lower surface of the first catch 31 to downward-extension.Coordinate by the first catch 31 and the second catch 32 catch that forms, protection effect is better.
Embodiment should not be considered as the restriction to utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
