Abstract
Description
technical field
[0001] The invention relates to a monitoring system for power transmission and transformation equipment, in particular to an on-line monitoring system for the dielectric loss angle of capacitive equipment. Background technique
[0002] Capacitive equipment is an important power transmission and transformation equipment, mainly including current transformers (TA), bushings, coupling capacitors, capacitive voltage transformers (CVT), etc., accounting for about 40% to 50% of the total substation equipment. It occupies an important position in the substation. Its insulation failure not only affects the safe operation of the entire substation, but also endangers the safety of other equipment and personal safety. At present, the maintenance work of power transmission and transformation equipment in my country is mainly to conduct regular preventive tests in accordance with the requirements of the "Electrical Equipment Preventive Test Regulations", that is, regular...
