Description
Technical field
The present invention relates to a kind of on-line monitoring system and monitoring method of the GIS internal high voltage conductor running temperature based on surface acoustic wave techniques, specifically refer to the on-line monitoring system based on the GIS internal breaker running temperature of surface acoustic wave techniques and monitoring method.
Background technology
Gas-insulated switch (Gas Insulated Switchgear, being called for short GIS) processing technology is strict, advanced technology, SF6 gas is adopted to be insulating medium, there is good connecting-disconnecting function, insulating property and arc extinction performance, and time between overhauls(TBO) length, failure rate is low, the advantage such as maintenance cost is few, floor area is little, be widely used at present in electric system.
But when the internal high voltage conductor contact in GIS device is bad, because contact resistance becomes large, can superheating phenomenon be produced load current flow is out-of-date.The overheated meeting of contact, bus causes insulation ag(e)ing even to puncture, thus causes short circuit, forms major accident, causes huge economic loss.Therefore, need to monitor the maximum temperature of high-pressure conductor.
The disconnector of gas-insulated switch inside, isolating switch and bus are the high-pressure conductor of gas-insulated switch, the maximum temperature value of disconnector often occurs in switch contact place, the maximum temperature value of isolating switch often occurs in the high pressure guide rod outside radome, high pressure guide rod outside radome is referred to as high pressure guide rod, the maximum temperature value of bus often occurs in bus contact place, is judge whether high-pressure conductor occurs the important means of superheating phenomenon to the monitoring of best temperature value.
In electric system, GIS is harsher to inner equipment requirement, and plenum interior does not allow to there is the magazines such as metal tip, burr and dust, and the maintenance of GIS with safeguard more complicated.Conventional art adopts temperature sensor directly to contact high-pressure conductor to the monitoring of high-pressure conductor maximum temperature value to carry out thermometric usually.Traditional temperature sensor needs externally fed or storage battery power supply, and the maintenance of equipment and the replacing of battery be inconvenience all very.So with regard to its way to take power, traditional temperature sensor is worthless.
Surface acoustic wave techniques is a kind of sensor technology of passive and wireless, the temperature sensor of surface acoustic wave techniques is adopted to be referred to as SAW Temperature Sensors, i.e. SAW temperature sensor, this SAW temperature sensor is the temperature sensor of passive and wireless, do not need power supply and connecting line during use, launch radio frequency signal by means of only collector to it and just can trigger its work as pumping signal.SAW temperature sensor has high sensitivity, low-power consumption, zero-emission, the feature such as non-maintaining, and design because SAW temperature sensor adopts hermetically sealed Multicarity to shield, there is extremely strong Electro Magnetic Compatibility and antijamming capability, and be furnished with unique antenna gate suppression undesired signal technology, almost can remove spatial electromagnetic interference completely, realize the on-line temperature monitoring under strong interference environment, the insulating property of existing equipment are not affected after installation, thus the on-line real time monitoring in the totally enclosed type spaces such as GIS device, the parts such as the such as high-pressure conductor of device interior being carried out to temperature is adapted at.
