6Gas belongs to high voltage electric power equip ment service technique field because of the device that effluve decomposes.
Background technology
Along with the development of power industry technologies, SF
6Gas has been used to replace in the past insulating oil material as insulation in the high voltage electric power equip ment and arc-extinguishing medium.So the stability of power equipment and reliability depend on SF fully
6The purity of gas, the stable operation that its analyte composition in the effluve environment and content thereof directly influence power equipment.Grasp high voltage electric power equip ment SF in use
6The situation of change of gas is the necessary link of service equipment safe operation, and this just needs regularly to detect SF
6The situation of change of gas.Prior art is under the situation of outage, directly extracts sample gas and detect from tested high voltage electric power equip ment, thereby seek under the condition of uniform temperature, pressure, humidity, energy SF
6The Changing Pattern of gas is as SF in the sample gas
6The composition of decomposing gas thing and content thereof etc. so that extract sample gas according to this rule in good time rather than regularly, are in time judged the operation conditions of power equipment on the one hand, thereby are got rid of the potential safety hazard of high voltage electric power equip ment, avoid unnecessary power failure on the other hand.
Summary of the invention
The technical matters that prior art exists at first is to guaranteeing handling safety, extract sample gas and must cut off supply network, therefore the power supply of surrounding area is affected, and the electric power facility that is connected with tested high-voltage electrical equipment is all out of service, especially for the urban electricity supply network, this method is restricted.In addition, prior art is to detect in real time, still can not grasp SF at short notice
6The variation of gas in the operation overall process of power equipment.Existing in order to replace from the net power equipment, extracting SF under the effluve
6The measure of decomposing gas sample gas, we have designed SF under the effluve of the utility model
