Method for researching influence of epoxy resin on SF6 trace products under discharge condition

Abstract

The invention discloses a method for researching the influence of epoxy resin on SF6 trace products under a discharge condition and belongs to the technical field of electric power. According to the epoxy resin-based SF6 trace product detection method, an isotope-labeled epoxy resin material part is replaced into SF6 gas insulation equipment, after a discharge test is carried out, variety and content change of isotope-containing substances in the SF6 gas trace product are measured by using detection equipment, the research on the SF6 trace product influence of the epoxy resin under the discharge condition is realized. According to the method, a problem that the sources of C, H and O elements in the SF6 trace product are unknown at present is solved, and the influence rule of the epoxy resin material on the SF6 trace product can be directly verified by using an isotopic tracer method. The research method provided by the invention can provide key and reliable data support for research on fault diagnosis and electric life evaluation of the SF6 gas insulation equipment by using a component analysis technology.

Description

technical field [0001] The invention belongs to the technical field of electric power, and relates to an epoxy resin to SF under discharge conditions. 6 Methods for the study of trace product effects. Background technique [0002] SF 6 Gas-insulated equipment is widely used in the power transmission and distribution system of the power grid because of its small footprint, safe and reliable operation, and long maintenance cycle. It plays a decisive role in the safe and stable operation of the power system. Partial discharge, spark discharge, arc discharge are SF 6 Common discharge phenomenon in gas-insulated equipment, which can cause SF 6 The gas decomposes to varying degrees and produces SF 5 , SF 4 , SF 2 And many other low fluoride sulfides. There are solid insulating materials, metal conductor materials and trace moisture and oxygen impurities inside the equipment. Under the action of discharge, SF 6 The low-fluorine sulfur compounds produced by gas decomposition...
