Humanized enterprise management, rational use of resources, protection of ecological balance, care for society, are the basic quality requirements of modern enterprise managers.

Former CCTV anchor Chai Jing's privately funded documentary on smog, "Under the Dome," was viewed more than 100 million times on the Internet in just two days. This has raised environmental concerns to an unprecedented level.

In the 103-minute film Under the Dome, Chai Jing visited multiple pollution sites to find the root causes of smog, and filmed pollution control experiences in many countries. The survey on smog is considered “ The haze survey conducted by non-organizations and non-journalists with authoritative information sources, three-dimensional information, broad vision, rich means and more sense of action” . At the previous exchange site, Chai Jing comprehensively used four means of public speech, on-site demonstration, video display and network communication to analyze the four major problems of coal burning and fuel oil, which have brought serious air pollution to China.

Through the deepening and upsurge of social awareness of haze, electrical equipment products filled with SF6 gas in power high-voltage equipment have also begun to enter the public's vision. In the last hundred years, the earth's climate is undergoing a significant change with global warming as the main feature. This global warming is caused by both natural climate fluctuations and the greenhouse effect, which is enhanced by human activities. Reducing greenhouse gas emissions and mitigating climate change are the main goals of the United Nations Convention on Climate Change and the Kyoto Protocol. Therefore, our country is facing more and more international pressure to reduce greenhouse gas emissions.

The greenhouse effect means that gases such as carbon dioxide in the atmosphere can heat up the Earth's surface through short-wave radiation from the sun. At the same time, it blocks the Earth's surface from emitting long-wave radiation into space, thus warming the atmosphere. Because of this effect of gases such as carbon dioxide and “ Greenhouse ” The function is similar, so it is called ” Greenhouse effect “ Gases such as carbon dioxide are called “ Greenhouse gases ” .

At present, it has been found that there are six kinds of greenhouse gases emitted by human activities, they are carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, among which three kinds of fluoride. Among them, CO2 has a great influence on the greenhouse effect, accounting for 60%, while the impact of SF6 gas only accounts for 0.1%. However, SF6 gas molecules have potential harm to the greenhouse effect, which is 25,000 times that of a molecule of SF6 gas on the greenhouse effect. At the same time, the life of SF6 gas emitted into the atmosphere is particularly long, about 3400 years. Today, the world emits 5,000 tons of SF6 gas into the atmosphere every year.

In Europe, there has long been considerable attention to the effective control and emission of SF6 gas, but Wevers Testing relies on the rich experience and technology of WINFOSS in Switzerland to develop a series of products for Swiss WINFOSS applications in China into domestic development application products and SF6 professional technical services. Through the re-development of SF6 related products, we have achieved excellent results in SF6 quantitative leak detection, SF6 infrared positioning leak detection, SF6 online leak monitoring system, SF6 recycling and treatment. It satisfies the SF6 gas detection of GIS equipment in the field of high pressure equipment, and makes the gas recovery and purification of GIS equipment achieve better results. Especially in the SF6 gas leakage and control to be more invested, such as SF6 leak online monitoring system, SF6 quantitative leak detector and other Wefus for the correct use of SF6 gas management, reduce SF6 gas emissions, in order to achieve as little as possible emissions requirements, for personal safety and environmental protection cause to make effective contributions.
