Abstract
The invention relates to a quantitative sulfur hexafluoride gas leakage alarm system which comprises a monitoring center, a PLC controller, an electron capture detector, a pressure sensor, a voice sound and light alarm, a solenoid valve and an air-exchange device. The monitoring center is in remote connection with the PLC controller; and the PLC controller is connected with the electron capture detector, the pressure sensor, the voice sound and light alarm, the solenoid valve and the air-exchange device. The system can monitor the concentration of sulfur hexafluoride in the air in real time, and if the concentration of sulfur hexafluoride exceeds standard, the system gives an alarm in time and exchanges air, thereby ensuring safety of work personnel in an electric appliance room; the electron capture detector is utilized to detect the sulfur hexafluoride gas, so that the system has the advantages of high sensitivity of the detector and high practicality; and the control center can remotely control the opening and closing of a sulfur hexafluoride standard gas bottle through the solenoid valve.
Description
Technical field
The present invention relates to electrical equipment monitoring technical field, 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 is easily revealed, and a large amount of leakages can cause indoor ischaemia, likely decomposites multiple toxic gas simultaneously, brings hidden trouble to the safety of staff.So need a kind of 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 sulfur hexafluoride gas and leak quantitative warning system.
Sulfur hexafluoride gas provided by the invention leaks quantitative warning system and is achieved through the following technical solutions:

A kind of sulfur hexafluoride gas as shown in Figure 1 leaks quantitative warning system, it is characterized in that: comprise Surveillance center, PLC, electron capture 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 electron capture detector, pressure transducer, voice audible-visual annunciator, solenoid valve, air interchanger respectively.
Further, described electron capture detector is made up of multiple sub-detecting device of electron capture being laid in electrical equipment other.
Further, described pressure transducer is arranged on sulfur hexafluoride gas bottle gas outlet.
Further, described solenoid valve is for controlling sulfur hexafluoride gas bottle gas flow.
Further, described air interchanger arranges sulfur hexafluoride filtration unit.
Electron capture detector is also a kind of ionization detector, it is a selectively highly sensitive detecting device, it is only to having electronegative material, material as halogen-containing, sulphur, phosphorus, nitrogen has signal, the electronegativity of material is stronger, and namely electronic absorption coefficient is larger, and the sensitivity of detecting device is higher, and the material to electric neutrality (without electronegativity), as the then no signal such as alkane.
The above embodiment only represents embodiments of the present invention, and it describes comparatively concrete and detailed, but can not be interpreted as limitation of the scope of the invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to scope.
