Description

Technical Field

[0002] In the process of transformation and construction of power grids, my country has long used a large number of rectangular busbars as the main equipment for connecting electrical equipment. However, rectangular busbars have obvious disadvantages: obvious skin effect and serious eddy current loss, accounting for about 20% of the loss of the entire substation system. From a national perspective, the amount of electricity lost due to line loss is very large. Therefore, power grid companies gradually use copper or aluminum metal tubular bare busbars to replace rectangular busbars, which is a big step in reducing losses. However, the use of bare busbars has not improved the power supply safety, and there will still be flashover accidents such as foreign body overlap, animal short circuit, climate temperature change condensation and human electric shock. Therefore, with the urgent need for safe transmission of large capacity and large current, the importance of using solid insulated intelligent busbar system has become increasingly prominent. Smart grid based on this is also a forward-looking trend of current development, and the intelligence of power equipment is an important cornerstone of smart grid. How to realize the intelligent and standardized collection of various monitoring data of solid insulated busbar, facilitate real-time transmission, report the status of transmission lines or conduct patrol inspections, is of great significance for fundamentally avoiding accidents and ensuring the safe and reliable operation of cables.
