Abstract: The ultra-high and extra-high voltage transformer substations have the high voltage level and the long safe distance with the high vertical height of the equipment, which brings great challenges for the installation and disassembly of the grounding wire. According to the requirement of the installation and disassembly of the grounding wire of ultra-high and extra-high voltage transformer substation, this paper developed a kind of portable pneumatic grounding device, introduced the structure and component design of short-circuit grounding device and calculated its related parameters. This device is successfully applied in the ultra-high and extra-high voltage transformer substations for the equipment to install and remove the grounding wire, with the features such as small volume, light weight, simple operation, safety and reliability and so on, which brings great convenience for the equipment overhaul work.
Key words: ultra-high voltage; extra-high voltage; transformer substation; portable; pneumatic; short-circuit grounding
