Abstract

The invention provides an expansion method for a sub-box type GIS bus cylinder. The expansion method comprises the steps that SF6 gas in a corresponding gas chamber in an original bus cylinder on a GIS interval to be expanded is recycled; splicing a newly added bus tube at one end, close to the air chamber, of the original bus tube; replacing an adsorbent in an adsorbent gas chamber on the original bus cylinder, and sealing the adsorbent chamber after replacement is completed; and SF6 gas is injected into the corresponding gas chamber on the expanded GIS interval. According to the invention, the working efficiency is improved, the splicing time of the bus cylinder is greatly shortened, the safety coefficient of the working personnel during working is improved, particularly, the time for recovering the production power consumption in advance is ensured, the normal operation of the expanded GIS interval is ensured, and considerable economic benefits are created.

Description

technical field [0001] The invention relates to the technical field of power system equipment installation, in particular to a method for expanding a box-type GIS bus barrel. Background technique [0002] In recent years, with the continuous increase of the power grid load, the existing GIS (gas insulated combined electrical equipment) needs to be upgraded. Expansion is an online transformation. Before the transformation, the power needs to be cut off, which will cause some users to be unable to use electricity and there are various gas chambers in the GIS interval. If it is not handled properly, it will cause gas leakage and affect the safety of the staff. It can be seen from this that, On-line busbar barrel docking operation has high safety risks, many uncertain factors, and the docking time should not be too long, so as not to affect normal production and electricity consumption and cause large economic losses. Contents of the invention [0003] In view of this, the pr...
