Abstract
The utility model relates to a cable accessory, in particular to a 500kV cable accessory which solves the problems that as for a conventional cable accessory, a partial discharge test can not be performed, insulating gas pressure is required to be monitored, and the product quality is affected due to possible oil leak phenomenon. The 500kV cable accessory comprises an outdoor terminal and a GIS (Gas Insulated Switchgear) terminal, wherein the outdoor terminal comprises a porcelain bushing type sleeve, a support seat is arranged in the sleeve and sleeved with a stress cone; a rubber part is arranged in the GIS terminal and sleeved on a cable; and a metal shielded electrode is embedded in an epoxy sleeve which is sleeved outside the rubber part. The 500kV cable accessory has a reasonable and reliable structural design, can reduce the influence on the quality stability of integrally-mounted terminal product due to cable structure size deviation and the technical level difference of mounting personnel, and improves the product combination property and long-time running stability; and the metal shielded electrode is embedded in the epoxy sleeve, so that the whole stress cone interface and the cable insulating interface are ensured to be stressed uniformly through a spring propping structure, and product mounting adaptability is wide.
Description
Technical field
The utility model relates to electric cable accessories, is specially a kind of 500kV electric cable accessories.
Background technology
Along with fast development of national economy, Chinese Urbanization is near 40%, and the city radius increases fast; Power load is more and more intensive; The radius of electricity supply of transformer station is more and more littler, and a large amount of transformer stations must get into the load center in city, and market increases substantially to the demand of cable thus.In cable system, cable production and technology are relatively ripe, and seriously the lag behind development of cable of the production technology of electric cable accessories needs a large amount of imports.The 500kV electric cable accessories comprises outdoor terminal and GIS terminal (indoor terminal) that links to each other through cable; Outdoor terminal adopts the form of porcelain bushing type tube electric capacity wimble structure more; Quality depends on on-the-spot mounting process fully, can't carry out local discharge test after the installation, the traditional oil-filled terminal of many employings, GIS terminal; Oil-filled terminal structure is simple, but product is once gas leakage, leakage of oil are bigger to electric property influence.
Summary of the invention
The utility model can't carry out local discharge test in order to solve the existing cable annex, need monitor and be prone to insulating gas pressure the problem that oil leakage phenomenon influences product quality takes place, and a kind of 500kV electric cable accessories is provided.
The utility model is to adopt following technical scheme to realize: the 500kV electric cable accessories; Comprise outdoor terminal and GIS terminal, outdoor terminal comprises the porcelain bushing type sleeve pipe, is provided with supporting seat in the porcelain bushing type sleeve pipe; Be with stress cone on the supporting seat; Be provided with the rubber parts that is enclosed within on the cable in the GIS terminal, rubber parts is with epoxy bushing outward, the inner metallic shield electrode that embeds of epoxy bushing.Through changing the sealing means of stress cone structural shape, make that product is easy for installation, the stress cone conductor construction is reliable, sealing is reliable; Epoxy bushing embedded metal bucking electrode; Improve the softness and the elasticity of stress cone elastomeric material; Change the stress cone structure, increase the lifting surface area of stress cone, make flexible rubber stress cone and cable insulation interface stressed more even; More appropriate cable outside diameter tolerance requirement, and then guaranteed the quality requirement of electric cable accessories.
The utility model reasonable in design is reliable, reduces construction of cable dimensional discrepancy and installation personnel difference of technology level, to the complete influence that back end product quality stability is installed, product combination property and long-time running stability is improved; The inner metallic shield electrode that embeds of epoxy bushing makes the spring top clamping structure guarantee that whole stress cone interface and cable insulation interface are stressed more even, and product installation adaptability is big.
