Problems solved by technology
[0004] However, the existing dust-proof sheds are simple in structure, and only fully enclosed fences are built around the GIS to block the invasion of wind and sand, making it difficult for the air dust and air relative humidity in the dust-proof shed to meet the requirements when installing or maintaining the GIS. Operational requirements lead to a high probability of failure of GIS during its later operation, which is likely to affect the stable operation of the substation where GIS is located and the power system
In addition, the dust-proof shed needs to be assembled on-site at the GIS installation and maintenance point, which takes a long time. pose a greater security risk

The invention discloses a dustproof room for GIS installation and maintenance and relates to the technical field of power equipment. The dustproof room is used for improving the installation and maintenance efficiency of a GIS and reducing the probability of a failure of the GIS. The dustproof room comprises a dustproof room main body capable of being carried to a GIS installation and maintenancepoint, wherein GIS placement openings are formed in the dustproof room main body and are provided with removable sealing curtains; a closed GIS installation and maintenance space is formed by the sealing curtains and the dustproof room main body; a plurality of lifting lugs are arranged outside the dustproof room main body; and a hoisting crane for hoisting the GIS, an environment control system for adjusting and controlling the environment of the GIS installation and maintenance space and a power supply lighting system for providing the hosting crane and the environment control system with electricity and lighting the GIS installation and maintenance space are arranged in the dustproof room main body separately. The dustproof room disclosed by the invention is applied to in-string equipment of the GIS.
Description
technical field [0001] The invention relates to the technical field of power equipment, in particular to a dust-proof room for GIS installation and maintenance. Background technique [0002] Gas-insulated switchgear (GIS for short) includes circuit breakers, isolating switches, earthing switches, lightning arresters, voltage transformers, current transformers, cable terminals and other equipment in substations except for transformers, all of which are directly or Indirectly sealed in the pipe tree composed of metal pipes and casings, and each pipe of the pipe tree is filled with a certain pressure of sulfur hexafluoride (SF6) insulating gas, so GIS is also called SF6 fully enclosed combined electrical appliance . [0003] At present, GIS has become one of the important components of substation due to its small footprint, compact structure and reliable operation. However, the reliable operation of GIS is inseparable from the installation and maintenance environment with a h...
