Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage power transmission, in particular to a plug-in GIS terminal for high-voltage power transmission. Background Art

[0002] Gas-insulated terminals are cable terminals installed in the gas-insulated part of gas-insulated enclosed switchgear (GIS) with sulfur hexafluoride (SF6) gas as the outer insulation. Gas-insulated terminals are also referred to as GIS terminals. They are essential products for SF6 combined electrical switches to realize cable entry. They are also used to connect cables to transformers. The terminal is filled with SF6 gas or transformer oil on the outside. GIS terminals should adopt a combined structure of prefabricated stress cones and epoxy sleeves. The conical tray with springs presses against the prefabricated stress cones to make them close to the conical wall of the epoxy sleeve. No insulating casting agent is required to be added to the terminal. The sealing performance is reliable, the insulation strength is high, the performance is stable, and it can meet the requirements of GIS switch and transformer operation. The GIS cable terminal and GIS switch should meet the IEC60859 matching size requirements. The long-term working temperature and current carrying capacity of the product can meet the requirements of the matching cable. The existing patent, patent announcement number CN216086122U, discloses a high-voltage cable plug-in GIS terminal anti-disengagement structure, which belongs to the technical field of the electrical industry. The high-voltage electrode is buried in the epoxy insulator, so that the high-voltage electrode and the epoxy insulator become one. The front end support column of the four support components is plugged into the upper load-bearing groove of the conductor outlet terminal, and the rear end clamping screw is threadedly connected with the lateral mounting hole of the high-voltage electrode. The two spring contact fingers are sleeved in the two grooves in the middle of the conductor outlet terminal. The advantages are: novel structure, convenient and fast operation, rigid support for the conductor outlet terminal and other components in the high-voltage cable plug-in GIS terminal, and the possibility of vertical displacement of the high-voltage cable plug-in GIS terminal is eliminated.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: in actual application, it is necessary to plug and unplug the connection. If it is inconvenient to plug and unplug the connection in actual application, it is inconvenient to perform buffering operations in the subsequent actual application, which reduces the convenience of using the terminal and reduces the efficiency of using the terminal. Therefore, we propose a plug-in GIS terminal for high-voltage transmission to solve the above-mentioned problems. Utility Model Content
