The invention discloses an experimental simulation device and method for arc discharge faults of gas-insulated electrical equipment, belonging to the technical field of on-line monitoring of the insulation state of sulfur hexafluoride gas-insulated electrical equipment, through basic circuits, relay control circuit modules, and delay control circuit modules , energy measurement system and gas detection system to simulate the arc fault of gas-insulated electrical equipment, simulate the experimental simulation device of arc discharge fault of gas-insulated electrical equipment through the experimental simulation method of arc discharge fault of gas-insulated electrical equipment, and solve the existing SF 6 The fault simulation laboratory device of gas-insulated electrical equipment cannot effectively simulate arc discharge faults, so it is necessary to construct a perfect SF 6 The fault diagnosis method of electrical equipment and the comprehensive evaluation system of the insulation state have laid a solid experimental foundation, and provide certain technical support for the online monitoring and evaluation of the insulation state of the equipment in the future.
Description
technical field [0001] The present invention belongs to sulfur hexafluoride (SF 6 ) The technical field of on-line monitoring of the insulation state of gas-insulated electrical equipment, in particular to a SF 6 An experimental simulation device and method for arc discharge faults of gas-insulated electrical equipment. Background technique [0002] SF 6 Gas insulated equipment (GIS, GIT, GIL, GCB, etc.) is widely used in the field of high-voltage and ultra-high voltage power transmission and transformation because of its small footprint, safe and reliable operation, small electromagnetic radiation, and long maintenance cycle. It has gradually become the first choice for the construction of modern urban power substations. In addition, the existing open conventional substations in the urban power grid are being gradually transformed and replaced by SF substations. 6 Gas-insulated closed substation. [0003] Thanks to SF 6 Gas-insulated equipment has high operational rel...
