Abstract
The utility model relates to a seal structure for arrester, including the arrester, sealed barrel, sealed lid and base, the arrester bottom is provided with takes fiery bolt, should take fiery bolt bottom and the coaxial suit of sealed barrel, admittedly, sealed lid is equipped with at the sealed barrel top, the fiery bolt of taking of arrester runs through sealed lid, a plurality of valve blocks are installed at the axial interval in sealed barrel, play sealed effect in the time of as the connection piece with taking the contact of fiery bolt, coaxial cover is equipped with insulating silica gel pad on the sealed barrel outer wall, at the coaxial multilayer silica gel full skirt that is provided with of this insulation silica gel pad, sealed barrel installs the base in the bottom. The utility model discloses an adopt high density insulation resin material preparation insulating cylinder, built -in zinc oxide valve plate, external silicon rubber insulation covers and the silicon rubber full skirt, satisfies the operation of different electric pressure equipment, and seal structure changes with the arrester, carries out the double containment protection, thoroughly stops into tide, repeatedly usable, long -time running.
Description
Technical field
The utility model belongs to field of electrical equipment, relates to lightning arrester, especially a kind of hermetically-sealed construction for lightning arrester.
Background technology
Often send out due to surge arrester failure in recent years and a large amount of lightning arrester all can be had defective when each periodic test, often propping up lightning arrester average price 1700 yuan, cause huge economic loss.Through we study find above-mentioned situation be lightning arrester with roll off the production line link time, lightning arrester is caused to take the hermetically-sealed construction of fiery screw bolt loosening damage lightning arrester owing to repeatedly taking fire, cause lightning-arrest enter damp insulation resistance for a long time and reducing and break down, this just needs the utility model and to change the status quo problem.
Utility model content
The purpose of this utility model is to overcome prior art deficiency, provides a kind of reasonable in design, can avoid repeating to take fire, fiery bolt is taken in twisting etc. to the infringement of lightning arrester hermetically-sealed construction the hermetically-sealed construction for lightning arrester.
The technical solution adopted in the utility model is:
A kind of hermetically-sealed construction for lightning arrester, comprise lightning arrester, sealing bucket, seal cover and pedestal, be provided with bottom lightning arrester and take fiery bolt, this takes fiery stud base and sealing bucket coaxial package, seal cover is fixed with at sealing bucket top, lightning arrester take fiery bolt-through seal cover, in sealing bucket, axially spaced-apart is provided with multiple valve block, as with the brace taking fiery threaded bolt contacts while play the effect of sealing, on sealing bucket outer wall, coaxial sleeve is equipped with Silicon-On-Insulator rubber cushion, multilayer silica gel full skirt is coaxially arranged with at this Silicon-On-Insulator rubber cushion, sealing bottom of the barrel is provided with pedestal.
And described valve block material is zinc oxide.
The utility model advantage and good effect are:
The utility model adopts high density insulating resin material to make insulating cylinder; built-in zinc oxide valve plate, external silicon rubber insulation covers and silicon rubber umbrella skirt, meets different electric pressure equipment and runs; lightning arrester hermetically-sealed construction is changed; implementation double containment is protected, and thoroughly stops into tide, reusable; long-time running; decrease engineering cost, effectively avoid the generation of surge arrester failure, reduce interruption duration.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below by accompanying drawing, the utility model is described in further detail in conjunction with specific embodiments, and following examples are descriptive, is not determinate, can not limit protection range of the present utility model with this.
A kind of hermetically-sealed construction for lightning arrester, comprise lightning arrester, sealing bucket 4, seal cover 2 and pedestal 8, be provided with bottom lightning arrester and take fiery bolt 1, this takes fiery stud base and sealing bucket coaxial package, be provided with along 3 at sealing bucket top and be fixed with seal cover, lightning arrester take fiery bolt-through seal cover, in sealing bucket, axially spaced-apart is provided with multiple zinc oxide valve plate 5, as with the brace taking fiery threaded bolt contacts while play the effect of sealing, on sealing bucket outer wall, coaxial sleeve is equipped with Silicon-On-Insulator rubber cushion 6, multilayer silica gel full skirt 7 is coaxially arranged with at this Silicon-On-Insulator rubber cushion, sealing bottom of the barrel is provided with pedestal.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
