Abstract

The invention relates to a GIS flange butt joint omni-directional lead-in device and method. The device comprises a positioning assembly and a guide assembly, wherein the positioning assembly is composed of more than three positioning pins, and the guide assembly is composed of more than three flexible guide rods. The positioning pins and the flexible guide rods are matched and used in a one-to-one correspondence mode. One end of each positioning pin is a cylindrical section, and the other end is a conical section. A metal ring is arranged at the end of the conical section, and metal fixing pieces are arranged at the two ends of the flexible guide rod. A G-shaped hook is arranged at the end of one of the metal fixing pieces and is used for being connected with a metal ring on the positioning pin in a hanging mode. Two stop pins are arranged on the two sides of the end of the other metal fixing piece. According to the device and method, the guide rod set and the positioning pin set areutilized, and precise, rapid and safe butt joint of a GIS flange is realized through a three-section introduction process. The device is simple in structure, the method is simple and feasible, and high practical application value is achieved.

Description

technical field [0001] The invention relates to the technical field of installation of GIS combined electrical appliances in substations, in particular to an omnidirectional introduction device and method for GIS flange docking. Background technique [0002] With the development of science and technology, the voltage level of the substation system has been continuously improved, the intelligent control has become more and more accurate, and the capacity of the transformer has been continuously improved. GIS (Gas-Insulated Metal-Enclosed Switchgear). GIS (GAS insulated SWITCHGEAR) is the English abbreviation of gas insulated fully enclosed combined electrical appliances. GIS consists of circuit breakers, isolating switches, grounding switches, transformers, arresters, busbars, connectors and outgoing terminals, etc. These devices or components are all enclosed in a metal grounded shell, and filled with a certain pressure of SF6 insulating gas inside , so it is also called S...
