Abstract

The utility model relates to an insulator conductor protective device used for GIS. A protection die head jointed with a conductor is installed along the direction in which the outer surface of the conductor extends upwards on an insulator conductor. The protection die head and the conductor are locked and positioned with a fastening bolt in between. An inner concave edge that is in line with the outer edge of the conductor and formed at the position where the protection die head is jointed with the conductor is wrapped at the periphery of the conductor. The conductor protective device can well solve the problem that the conductor is bumped, touched, scraped and even cut by a die during the installation process of the conductor, thus avoiding the scrape metal generated during the installation process of dies, further greatly reducing the possibility that the scrape metal is mixed in an epoxy resin casting piece, and effectively improving the electric safety of the epoxy resin casting piece.

Description

GIS insulator conductor protective device

Technical field:

The utility model belongs to the power transmission and distribution field, relates to a kind of protective device of power transmission and distribution switch element, particularly relates to a kind of GIS insulator conductor protective device.

Background technology:

GIS (Gas Insulated Switchgear) fully closed combined electric unit is with excellent characteristics such as its compact conformation, voltage range be wide, safe and reliable to operation, day by day to the epoch of Towards Higher Voltage and load densification development, presented extremely strong vitality in power industry.The epoxy resins insulation pouring piece is as the crucial insulating element among the GIS, and not only use amount is increasing, and also more and more harsher to the requirement of its electric property, becomes the fundamental that constitutes the GIS insulating reliability.

GIS mostly is to adopt the epoxide resin vacuum pouring technology with the production of epoxy resins insulation pouring piece, have and be mixed with metal impurities in the mould material and influence the bad principal element of poured with epoxy resin spare electric property, pouring piece air entrapment etc., wherein the metal impurities in the mould material are avoiding greatly of insulation pouring spare production, it also is the main reason that causes the pouring piece electric property bad, the source of metal impurities mainly is when adopting vacuum pouring technology to make insulated product, because of the GIS used conductor inserts of epoxy resins insulation pouring piece, adopt good aluminium or the copper material of electric conductivity to make mostly, and the pouring piece cast is used steel material substantially with mould, because both material hardnesses are different, when colliding with, conductor is easily produced chip by scraping, and GIS is big with the insulator product size, need to use big and heavy mould to make, mould need use plant equipment to cooperate with manpower when matched moulds is installed, so a side template very easily collides with and swipes with the conductor that is fixed on the opposite side template when mould is installed, thereby produce the inner chamber after metal fragment falls into matched moulds, thereby sneak into the mould material of perfusion after this, influence the electric property of goods.

For reducing the metal impurities problem that above-mentioned insulation pouring spare exists in making, the inventor has designed GIS with the conductor protective device that uses in the disc insulator manufacture process, and this case produces thus

Summary of the invention:

The purpose of this utility model is to provide a kind of reused conductor protective device in making GIS usefulness disc insulator process; it can farthest reduce in the manufacturing process metal impurities sneaks in the insulation pouring material, guarantees the electrical property of GIS with disc insulator.

For reaching above-mentioned purpose, the utility model adopts following technical scheme:

GIS extends upward direction applying conductor at insulator conductor upper edge conductor outer surface and is provided with a protection die head with insulator conductor protective device, borrows the fastening bolt locking positioning between protection die head and conductor.

Described protection die head applying conductor place forms the iner ledge that matches with the conductor outer rim and is coated on the conductor periphery.

The periphery that described protection die head is not fitted with conductor form slick and sly arc closing in structure in case mould when installing the center hole of a side template can be inserted in easily in the protection die head.

After adopting technique scheme; mould is when installing matched moulds; because the protection die head is equipped with on conductor top; template can directly not contact with the conductor upper surface; and at the protection die head that the conductor upper surface extends is to be made by the material (as polytetrafluoroethylene etc.) that the material suitable with mould hardness or other do not produce electrically-conductive debris; be difficult for being produced metal fragment by the mould scratch; the protection die head also can play guide effect when matched moulds simultaneously; avoid conductor in the mould installation process, to be produced metal fragment by the mould scratch of colliding with; so; after the technical program is implemented; can farthest avoid producing metal fragment in the mould matched moulds process; and then significantly reduce the possibility of pick-up metal chip in the poured with epoxy resin spare, improved the electrical security of poured with epoxy resin spare effectively.
