Problems solved by technology

[0002] With the development of power distribution network, a large number of complete switchgears are used in medium and low voltage systems. Due to various factors such as equipment reasons and operating environment, arc fault accidents occur frequently in switchgear electrical equipment, and arc faults on medium and low voltage buses have serious consequences. Rapid development, unpredictable, destructive power, etc., can cause serious consequences such as switchgear, busbar burning or explosion, and operator casualties; Pressure relief measures, resulting in damage to adjacent switchgear as well
