Abstract
The present invention relates to a kind of modified sulfur hexafluoride gas and leak quantitative warning system, comprise Surveillance center, PLC, infrared spectrum detector, pressure transducer, voice audible-visual annunciator, solenoid valve, air interchanger, described Surveillance center is connected with PLC is long-range, and described PLC connects infrared spectrum detector, pressure transducer, voice audible-visual annunciator, solenoid valve, air interchanger respectively.The present invention can the concentration of sulfur hexafluoride in Real-Time Monitoring air, if exceeded standard, and alarm, and take a breath, ensure that the safety of staff in electric apparatus room; Adopt infrared spectrum detector to detect sulfur hexafluoride gas, have that sensitivity is higher, antijamming capability is strong, willing advantage; Control center can pass through solenoid valve, the opening and closing of Long-distance Control sulfur hexafluoride gas bottle.
Description
Technical field
The present invention relates to electrical equipment monitoring technical field, modified sulfur hexafluoride gas leaks quantitative warning system specifically.
Background technology
Sulfur hexafluoride (SF
6) there is good electrical insulation properties and the arc extinction performance of excellence, its electric strength is 2.5 times of nitrogen under same pressure, voltage breakdown is 2.5 times of air, and arc extinguishing ability is 100 times of air, is a kind of UHV (ultra-high voltage) insulating dielectric materials of new generation be better than between air and oil.Because sulfur hexafluoride is with its good insulating property and arc extinction performance, is widely used in isolating switch, high-tension transformer, sealing gland close combined capacitor, hv transmission line, mutual inductor etc.In annual about 8500t sulfur hexafluoride (SF6) gas produced in the whole world, about have over half for power industry.But, owing to being subject to many factors, SF
6electrical equipment easily leaks, and a large amount of leakages can cause indoor ischaemia, likely decomposites multiple toxic gas simultaneously, brings hidden trouble to the safety of staff.Conventional sulfur hexafluoride pick-up unit is gas sensor, although its one-tenth is low, needs sulfur hexafluoride to leak a period of time and just can detect, delay of response.So need a kind of modified sulfur hexafluoride gas badly to leak quantitative warning system to solve the problem.
Summary of the invention
Not enough for above-mentioned prior art, the invention provides a kind of modified sulfur hexafluoride gas and leak quantitative warning system.
Modified sulfur hexafluoride gas provided by the invention leaks quantitative warning system and is achieved through the following technical solutions:
A kind of modified sulfur hexafluoride gas leaks quantitative warning system, it is characterized in that: comprise Surveillance center, PLC, infrared spectrum detector, pressure transducer, voice audible-visual annunciator, solenoid valve, air interchanger, described Surveillance center is connected with PLC is long-range, and described PLC connects infrared spectrum detector, pressure transducer, voice audible-visual annunciator, solenoid valve, air interchanger respectively.
Described pressure transducer is arranged on sulfur hexafluoride gas bottle gas outlet.
Described solenoid valve is for controlling sulfur hexafluoride gas bottle gas flow.
Described air interchanger is arranged sulfur hexafluoride filtration unit.
The invention has the beneficial effects as follows:
1, can the concentration of sulfur hexafluoride in Real-Time Monitoring air, if exceeded standard, and alarm, and take a breath, ensure that the safety of staff in electric apparatus room;
2, infrared spectrum detector is adopted to detect sulfur hexafluoride gas, have highly sensitive, not by impact and the interference of environment, the advantage that the metrical error brought the change of the temperature and humidity of environment is very little, because it adopts the principle initiatively extracting test point gas, the effect brought finds to leak early, and be swift in response, simultaneity factor structure also brings very large convenience to the wiring in engineering construction.
3, control center can pass through solenoid valve, the opening and closing of Long-distance Control sulfur hexafluoride gas bottle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
