Description

Technical Field

[0001] The utility model mainly relates to the technical field of electric power equipment, and in particular to a detachable conductor device for GIS equipment in a substation. Background Art

[0002] In the high-voltage power transmission and transformation system, substation GIS equipment has been widely used. As one of the main components of GIS equipment, voltage transformers and lightning arresters are widely used. The function of the voltage transformer is to convert high voltage into standard low voltage in proportion to achieve standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment; isolate high voltage to ensure the safety of staff and equipment. The function of the lightning arrester is to effectively protect power equipment and play a protective role when abnormal voltage occurs. However, during the GIS withstand voltage test, the voltage transformer and lightning arrester cannot withstand voltage as a whole. In the absence of an isolation fracture, the voltage transformer and lightning arrester must be removed and then withstand voltage at intervals. After the withstand voltage is completed, they can be installed. However, the above method requires on-site disassembly and assembly, which is a large workload. Utility Model Content
