SF6 gas on-line monitoring system

Abstract

The invention relates to the technical field of gas monitoring, in particular to an SF6 gas online monitoring system comprising a sulfur hexafluoride gas detector and a monitoring system. A fixed plate is arranged on the surface of the sulfur hexafluoride gas detector; a wall connecting screw is arranged on the surface of the fixed plate, a base plate is arranged on the surface of the sulfur hexafluoride gas detector, a guide groove is formed in the surface of the base plate, a sliding plate is arranged in the guide groove, balls are arranged on the surface of the sliding plate, a telescopic plate is connected to the surface of the guide groove, and the telescopic plate is inserted into the telescopic groove. The beneficial effects of the SF6 gas online monitoring system are that: the sliding type cleaning plate is additionally arranged on the surface of the sulfur hexafluoride gas detector and can slide along the display screen on the surface of the sulfur hexafluoride gas detector toremove ash; telescopic plates are inserted into the upper side and the lower side of the connecting plate on the surface of the cleaning plate to pull the sliding plate, and the extension height of the telescopic plates is adjustable, so that the cleaning plate can be conveniently fixed at different heights.

Description

technical field [0001] The invention relates to the technical field of gas monitoring, in particular to an SF6 gas online monitoring system. Background technique [0002] SF6 is a suffocating agent, which can cause breathing difficulties, wheezing, bluish skin and mucous membranes, and general convulsions at high concentrations. After inhaling the mixed gas of 80% sulfur hexafluoride + 20% oxygen for a few minutes, the human body will experience numbness in the limbs and even suffocate to death. my country stipulates that the allowable concentration of sulfur hexafluoride gas in the air in the operating room should not exceed 6g / m3 or the oxygen content in the air should be greater than 18%; for short-term exposure, the allowable concentration of sulfur hexafluoride gas in the air should not exceed 7.5g / m3. Sulfur hexafluoride is an inert gas in pharmacology, low toxicity but has a suffocating effect on the human body. During life or use, some traces of toxic sulfur-based ...

Problems solved by technology

[0003] In the prior art, the sulfur hexafluoride gas detector is usually installed on the wall. The long-term attachment of the sulfur hexafluoride gas detector to the wall is not only prone to moisture, but also not conducive to the heat dissipation of the backplane of the sulfur hexafluoride gas detector; During long-term use, a large amount of dust and dirt adhere to the display screen surface of the sulfur hexafluoride gas detector, which affects the look and feel of the display screen
