Abstract
The utility model discloses a mounting flange for a fully-optical current transformer and GIS (geographic information system) combination, which comprises a mounting flange body. The mounting flange body is connected with a GIS gas chamber. The mounting flange is characterized in that three mounting through holes are arranged on the mounting flange body, primary conductors penetrate through the mounting through holes, a groove is disposed on one side of the mounting flange body, a fully-optical current transformer penetrates through the mounting through holes prior to being fixedly mounted in the groove of the mounting flange body, insulating pads are disposed at sealed connection openings of an upper flange cover and the mounting through holes and realize sealing and insulation effect, and induction current of the flange and the upper flange cover in the fully-optical transformer is isolated. The mounting flange meets the requirement of sealing performance when a traditional transformer and a GIS combined electrical appliance are connected and mounted, and the overall volume of the GIS electrical appliance is reduced.
Description
Technical field
The utility model relates to a kind of full optical current mutual inductor mounting flange, the adpting flange of the same GIS of particularly a kind of full optical current mutual inductor (high pressure combined electrical apparatus) aggregate erection formula.
Background technology
Full optical current mutual inductor has volume characteristics little, flexible for installation, and it installs with traditional electromagnetic transformer different.With the GIS aggregate erection time; In order to solve full optical current mutual inductor with GIS combined electrical apparatus butt joint problem; Solve relevant insulation, encapsulation process problem, consider to embody the little advantage of full optical current mutual inductor volume simultaneously, need a kind of connection method that is different from traditional instrument transformer of design.
The utility model content
The utility model technical problem to be solved is, overcomes the shortcoming of prior art, and a kind of full optical current mutual inductor GIS aggregate erection flange is provided, and can make full optical current mutual inductor with the connection of GIS combined electrical apparatus easily.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of full optical current mutual inductor GIS aggregate erection flange; Comprise the mounting flange that links to each other with GIS air chamber one; It is characterized in that: have 3 installation through holes that are used for through Primary Conductor on the mounting flange; Mounting flange one side is provided with groove; Be fixedly mounted in the groove of mounting flange after full optical current mutual inductor passes installation through holes, the flange loam cake is connected sealing part and is provided with insulation cushion and seals and insulate with installation through holes, cuts off flange and flange loam cake at the induced current of optics instrument transformer inside entirely.
Aforesaid full optical current mutual inductor GIS aggregate erection flange, it is characterized in that: said insulation cushion is an epoxy resin board.
Aforesaid full optical current mutual inductor GIS aggregate erection flange, it is characterized in that: the mounting flange outer ledge is provided with secondary optical fiber line outlet, is used to draw the outlet of full optical current mutual inductor secondary optical fiber.
Aforesaid full optical current mutual inductor GIS aggregate erection flange is characterized in that: said insulation cushion is placed in the outer peripheral convex holddown groove of installation through holes in the mounting flange groove.
Aforesaid full optical current mutual inductor GIS aggregate erection flange is characterized in that: between mounting flange and the air chamber one, seal through sealing ring between flange loam cake and the air chamber two.
The beneficial effect of the utility model is: connect through flange between each air chamber of GIS combined electrical apparatus of the utility model; Traditional instrument transformer need be installed in the GIS air chamber; Connect with other air chambers of GIS through the GIS flange then, thereby accomplish the installation of instrument transformer with GIS.According to its characteristics that Secondary Part insulate, volume is little of full optics instrument transformer; The mounting flange of the utility model is transformed traditional mounting flange, full optical current mutual inductor is sunk to flange inside, like this; After the connection of this flange completion GIS air chamber; Also accomplished the installation of full optical current mutual inductor, the sealing property requirement that has existed when having solved traditional instrument transformer with the connection of GIS combined electrical apparatus, and reduced GIS electrical equipment overall volume greatly.
