    • 专利摘要:
    An encased gas-insulated high-tension line is disclosed especially for regions of the line where disturbing arcs can occur so as to melt a grounding casing of the line. A heat and pressure resistant insulative layer prevents an escape of hot and possibly poisonous insulating gases from the casing in the event of a casing melting. The insulative layer is preferably made of an epoxy resin/glass fiber fabric and is wound around arc-endangered areas at fixed arc regions. An additional heat-resistant insertion may be included between the casing and the insulative layer.

    专利说明:

    The invention relates to electrical engineering, in particular to a sealed high-voltage gas-insulated line. A well-known hermetically sealed gas-insulated high-voltage line containing a conductor mounted on n insulators in a housing. In this line, the body consists of an insulating material into which a metal screen of mesh braid or foil is inserted. Metallic. the screen provided for the limitation of the electric field is connected from outside by direct current to the ground bus bars, which are located inside the housing and are rigidly connected to it. The metal grounding busbars are designed in such a way that they can conduct an electric arc for a sufficiently long time or can conduct it to a predetermined burning point in which the electric arc can remain until the high-voltage line Cll is turned off. However, this device is characterized by laboriousness and large dimensions, as well as lack of reliability. Closest to the proposed technical accuracy and the achieved effect is a sealed high-voltage gas-insulated line containing a conductor mounted on the supporting insulators in an earthen metal case having heat-resistant protective elements in the known device. screens installed on the inner side of the case and separated from it by asbestos plates. This causes a large diameter of the hull in arc-hazardous areas and significantly increases the cost of the line. The purpose of the invention is to reduce labor costs, l and manufacturing. The goal is reached. That 3 well-known gas-insulated high-voltage lines are heat-resistant protective elements located on the outer side of the case and each of them is made in the form of a bandage made of thermosetting resin reinforced with glass fiber. At the same time, bandages on the sites of different thermal hazards have different thicknesses. Such an embodiment of the line makes it possible to significantly reduce costs, since the protective elements in this case are not exposed to the base of the electric arc and therefore consist of a heat-resistant material, but not directly shielding the effect of the arc. In this case, the protective elements 1) can be applied to existing lines without dismantling and decommissioning. At the same time, the protective elements give the case an increased cracking strength. FIG. 1 image | Eazhena sealed gas-insulated high-voltage line, longitudinal section; Figures 2 and 3. Parts of the casing walls of an insulated high-voltage line with shells of insulating material in places that are dangerous for an electric arc, longitudinal section, .- /,. . - .. Sealed gas-insulated high-voltage line will contain electrical conductor 1, mounted on supporting insulators 2 in an airtight metal housing made of cylindrical tubes 3 and k, which are hermetically connected by flanges 5 and b. Moreover, between these flanges or in the sealed flange grooves a hermetically sealed insulator 2 is installed. The wall thicknesses of the metal pipes are selected in accordance with the gas pressure, which can reach 10 bar, according to the working conditions. When making the body of aluminum, the wall thickness can be 2-12 mm, while the fused aluminum pipes with a smaller thickness are preferably made of spirally welded aluminum tape. In a dangerous, from the point of view of arcing, areas are located protective heat-resistant elet5 | 7 in the form of a bandage from a thermosetting resin, in particular, from epoxy resin, reinforced with fiberglass (fiberglass or fiberglass plain). Hazardous are, in particular, pipe sections with a reduced diameter or with a reduced wall thickness, or with unstable places, such as passages: insulators, corner sections of conductors 1 or areas with a strong curvature of the conductor and stationary
