Embodiment 1

[0060] The structure of the GIS provided by this embodiment is as follows figure 1 and figure 2 As shown, the GIS housing 100 is included, and the three-phase GIS conductors 300 are arranged in the GIS housing 100, which are A-phase conductors, B-phase conductors and C-phase conductors respectively, and installation holes are respectively provided on the GIS housing 100 corresponding to the three-phase conductors 200, wherein the first charging display device 101 is respectively installed in the two installation holes 200 corresponding to the A-phase conductor and the B-phase conductor, and the second charging display device 102 is installed in the installation hole 200 corresponding to the C-phase conductor. The display device 101 and the second charging display device 102 are detachably fixed and installed at the openings of the corresponding mounting holes 200 respectively by bolts. The difference between the first charging display device 101 and the second charging displa...

specific Embodiment 2

[0073] The main difference between it and Embodiment 1 is that in Embodiment 1, the ring-shaped sieve frame makes the water adsorption structure a ring-shaped structure, which is convenient to fit outside the signal transmission rod. In this embodiment, the water adsorption structure may also be a plurality of independently distributed cube structures, including a square screen frame, and it is only necessary to arrange an adsorbent inside each screen frame.

specific Embodiment 3

[0075] The main difference between it and Embodiment 1 is that in Embodiment 1, the water adsorption structure adopts a screen frame structure, which facilitates the replacement of the internal adsorbent. In this embodiment, the water adsorption structure may also adopt a flexible mesh bag, and the flexible mesh bag is filled with an adsorbent to ensure effective adsorption and removal of water.

Abstract

The invention relates to an electrified display device for a GIS (Gas Insulated Switchgear) and the GIS. The electrified display device comprises a cover plate, a signal detection structure installed on the cover plate in an insulating mode, and a water adsorption structure; the signal detection structure comprises an electricity taking structure and a cable connecting structure, the electricity taking structure is located on the inner side of the cover plate and used for taking electricity from a corresponding GIS conductor in the GIS shell, and the cable connecting structure is used for being conductively connected with an external cable; the water adsorption structure is detachably and fixedly mounted on the inner side of the cover plate. In the electrified display device, not only is the signal detection structure arranged, but also the water adsorption structure is integrally arranged, so that for the GIS shell, only a single mounting hole is formed for the electrified display device, more mounting holes do not need to be additionally formed, the leakage risk is reduced, and the assembly process is simplified. In fact, after the two functions are integrated, the number of parts is greatly reduced, the part cost is reduced, the production cycle is shortened, the stability of products is improved, and finally benefits are increased for enterprises.

Description

technical field [0001] The invention belongs to the technical field of gas insulated switches, and in particular relates to a charged display device for GIS and the GIS. Background technique [0002] In recent years, as power grid users pay more and more attention to the safe operation of high-voltage switch products, combined electrical products are widely used in power systems due to their small footprint, small size, high reliability, and almost no maintenance. All kinds of protection and detection methods are constantly emerging with combined electrical appliances as the carrier. Due to the compact structure, all kinds of components in combined electrical appliances should be highly concentrated, which is convenient for further reducing the size of combined electrical appliances, improving the actual engineering layout capabilities of combined electrical appliances, reducing manufacturing costs, and ultimately improving market competitiveness. The charging display devic...
