Abstract
The invention discloses a double-gas detector for detecting leakage of sulfur hexafluoride gas and oxygen gas. The detector comprises a double-gas detector body, wherein the double-gas detector body comprises a sulfur hexafluoride purity analyzing sensor, an oxygen content analyzing sensor, a wireless transmitting module, a microprocessor and a power module. The double-gas detector is mounted on a telescopic rod capable of adjusting three sections, the length can be arbitrarily adjusted according to needs, and the use is convenient; and the wireless transmitting module is adopted, so wireless data transmission between the double-gas detector and a matched handheld receiver can be realized, and the operation is convenient. The double-gas detector can correct the sensitivity of the detector at any time in a detection process and compare with an online monitoring device through detection data displayed on the handheld receiver on site to discover whether the online monitoring device is in a normal working state or not, so the double-gas detector disclosed by the invention has the characteristics of high sensitivity, stability and reliability and the like.
Description
Technical field
The present invention relates to a kind of Leakage Gas checkout equipment, relate in particular to a kind of portable pair of gas detecting instrument for sulfur hexafluoride gas and oxygen leakage detection.
Background technology
Sulfur hexafluoride gas is widely used in high-voltage switch gear, transformer and fully closed combined electric unit (GIS) etc. high-tension apparatus as a kind of insulating medium of excellence.Due to the aspects such as production, processing and installation of equipment, the leakage that slowly can produce sulfur hexafluoride gas.If can not in time find the leakage situation of gas, in case when leaking the concentration value that reaches certain, sulfur hexafluoride gas is known from experience the serious injury of generation to the people.
This power industry has been formulated many relevant safe operation standards for sulfur hexafluoride gas equipment, wherein emphasized the warning instrument that sulfur hexafluoride gas and oxygen content detect must be installed in the switch gear room that sulfur hexafluoride gas is arranged.Be placed on the ground of switch gear room due to the long device of these detecting instruments, the temperature of air, humidity and foreign gas have a huge impact the sensitivity meeting of on-line monitoring.If these online monitoring alarm devices are in case malfunctioning its due security role that just lost.Personnel's safety still is difficult to be protected.In these more external outdoor or variable environment, be not easy to install online sulfur hexafluoride warning device.
Summary of the invention
Purpose of the present invention, a kind of two gas detecting instruments for sulfur hexafluoride gas and oxygen leakage detection are provided in order to address the above problem exactly, detect the leakage of sulfur hexafluoride gas in portable mode, and then judge that accurately whether high-voltage switch gear, transformer and fully closed combined electric unit (GIS) etc. high-tension apparatus has sulfur hexafluoride gas to leak, and ensures the device of the safe operation of electric system.
