Abstract

The present invention provides a SF6 online monitoring apparatus accuracy detection system and a method thereof. The system comprises a gas generation apparatus, a gas container, a temperature control box, an offline type SF6 precision measurement instrument and a SF6 gas recovery device, and is characterized in that the gas generation apparatus is a gas dew point generator or standard gas, and is connected with the gas container, the gas container is provided with a thermometer, a pressure gauge and a density monitoring device, and is connected with the SF6 online monitoring device and the offline type SF6 precision measurement instrument, the offline type SF6 precision measurement instrument comprises a cold mirror type SF6 dew point meter and a SF6 decomposition product tester, and the SF6 gas recovery device is provided for detected SF 6 gas recovery. With the present invention, SF6 online monitoring apparatus accuracy detection can be achieved, detection results have traceability and high reliability, effects of the SF6 online monitoring apparatus in an electric power system can be substantially increased, and safety of the electric power system can be improved.

Description

technical field [0001] The invention relates to an online monitoring device for power transmission and transformation equipment in a power system—a detection system and method for the accuracy of the SF6 online monitoring device. The gas container is used to simulate the SF6 power transmission and transformation equipment, and the offline SF6 with higher accuracy is used. A parameter measuring device detects the measurement accuracy of an SF6 on-line monitoring device, and belongs to the technical field of electrician measurement and detection. Background technique [0002] Power transmission and transformation equipment is very important equipment in the power system, and its operating status directly affects the security of the system. The traditional "planned maintenance" in the power system ignores the actual operation status of the equipment, has great blindness and compulsion, and has great defects. In order to discover the early defects of electrical equipment in tim...
