You may have encountered the following problems?With the continuous development of the power system, the application of SF6 electrical equipment is becoming more and more extensive, especially the GIS combined electrical appliances have the advantages of greatly reducing the floor space and space volume of the electrical equipment, convenient installation, safe and reliable operation, and convenient maintenance. Urbanization and more polluted places make it the best choice for now. However, because the specific gravity of SF6 gas is 5 times that of air, it is easy to accumulate in the bottom space. After reaching a certain concentration, if the staff enters the room, it will cause hypoxia to the brain, suffocate people, and cause major accidents. In addition, under the conditions of high temperature and partial discharge, SF6 gas will be decomposed into toxic substances, which will cause personal injury. Therefore, "Electrical Safety Work Regulations" (electrical parts of power plants and substations) specifically stipulates that the power distribution room equipped with SF6 equipment must ensure that the concentration of SF6 gas is less than 1000ppm. Monitoring equipment such as oxygen meter and SF6 gas density detection alarm. Therefore, in the past 10 years, the SF6 gas monitoring equipment and alarm systems installed in major domestic substations have sprung up like mushrooms after a rain, which is dazzling. But the problem also follows:
1. In the past 10 years, are the monitoring data of these monitoring equipment accurate or not? Who can give users a reliable assessment of the operating conditions of these monitoring devices?
2. As the power grid management, do you have great confidence or doubts about the monitoring equipment currently in operation in the power grid? Can you accurately tell me that the monitoring equipment manufacturer chosen this year is stronger than the one chosen last year? Who can provide users with a strong judgment basis.
3. As a power inspection personnel, when you enter a workplace equipped with SF6 equipment, you see that many SF6 gas leakage monitoring devices always display normal data, are you very confident, or are you slightly worried?
4. As a monitoring equipment manufacturer, can you confidently pat your chest with users to ensure that there is no problem with the quality and accuracy of your products? Can anyone vouch for you? Who can provide you with third-party affirmation and support?

Do you know the current status of the SF6 leak detection industry?

Background analysis: Since the 1960s, SF6 gas has been widely used in power systems due to its excellent insulation and arc extinguishing properties, and has almost become the only insulating and arc extinguishing medium used in medium voltage, high voltage and ultra-high voltage switches. . Because of the large-scale use of SF6 gas, its safety has also received widespread attention. The leakage of SF6 gas has attracted enough attention, and the related SF6 gas leak detection instruments have also attracted the attention of industry personnel.

Technical analysis: SF6 leak detectors can generally be divided into qualitative leak detectors and quantitative leak detectors. Qualitative leak detectors generally have low accuracy, are easy to carry and are cheap; while quantitative leak detectors are often used for high accuracy requirements and frequent use. high places. The principle of these products is roughly the same. Most of them use the corona principle to capture negative polarity. The basic working method is that there is a miniature sensor at the head of the detector hose. The sensor is made of an alloy material and can generate about 2000v during operation. The micro-current is high-voltage, and the fluorine molecules entering the hose end generate different electrical signals in the high-voltage state, with different concentrations and different electrical signal strengths. There are many types of quantitative leak detectors on the market. We can generally divide them into high-frequency magnetic field ionization, infrared, laser, electron capture detector (ECD), laser photo-acoustic detection principle, and negative ion capture according to the principle.

Analysis of the current situation of domestic leakage detection operation: According to the relevant regulations of the safety management of the State Grid industry, the relevant power bureaus of the State Grid have carried out real-time online monitoring of SF6 leakage in most of its subordinate SF6 substations since 2000, so as to ensure the personal safety of those who enter the substation environment. It is safe, but also facilitates the diagnosis of the severity of the leakage of each air chamber septum. But up to now, due to the different applications of substation projects and the existence of equipment from different manufacturers, the technical principles and technical levels are quite different. In addition, usually for testing equipment, the country has relevant standards, and the general verification period should not exceed two years. Therefore, in order to effectively improve the safety management level of substations and curb the occurrence of safety accidents. It is necessary to systematically and conveniently carry out a full-scale verification, maintenance and maintenance of the SF6 leakage monitoring equipment put into operation within the jurisdiction.
