SF6 Leak detection calibration service

You may be experiencing the following problems?

With the continuous development of the power system, SF6 electrical equipment is more and more widely used, especially GIS combined electrical equipment because it greatly reduces the floor area and space volume of electrical equipment, easy installation, safe and reliable operation, convenient maintenance and other advantages, in the urbanization construction and pollution more serious places, make the current choice. However, because the proportion of SF6 gas is 5 times that of air, it is easy to gather in the bottom space, and after reaching a certain concentration, if the staff enters the room, it will cause brain hypoxia, suffocate people, and cause a major accident. In addition, under the condition of high temperature and partial discharge, SF6 gas will decompose into toxic substances, which will cause personnel injury. Therefore, the "Electrical safety Work Regulations" (electrical part of power plants and substations) specifically stipulates that the distribution unit room equipped with SF6 equipment must ensure that the SF6 gas concentration is less than 1000ppm, and in addition to the installation of strong ventilation devices, it must also install monitoring equipment such as oxygen meters and SF6 gas density detection and alarm meters. Therefore, in the past 10 years, SF6 gas monitoring equipment and alarm systems installed by major substations in China have mushroomed in large numbers, which is dazzling. But here's the problem:

1, Over the past 10 years, the monitoring data of these monitoring equipment is accurate or not? Who can give users a reliable assessment of the health of these monitoring equipment?

2, as the power grid management, the current grid in the operation of these monitoring equipment is very confident or skeptical? Can you accurately tell me that the monitoring equipment manufacturer selected this year is stronger than the manufacturer selected last year? Who can provide users with a strong basis for judgment.

3, as a power transportation inspection personnel, when you enter the workplace equipped with SF6 equipment, watching many SF6 gas leakage monitoring equipment always show normal data, is your heart very confident, or will you be a little worried?

4, as a monitoring equipment manufacturers, really can be justified with the user to pat the chest to ensure that your product quality and accuracy is no problem? Can anyone vouch for you? Who can provide you with third-party recognition and support?

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

Background analysis: Since the 1960s, SF6 gas has been widely used in power systems for its excellent insulation and arc extinguishing performance, and has become almost the only insulation and arc extinguishing medium used in medium voltage, high voltage and ultra-high voltage switches. Because of the extensive use of SF6 gas, its safety has also been widely concerned. The leakage problem of SF6 gas has aroused enough attention, and the related SF6 gas leak detection instrument has also been concerned by the industry personnel.

Technical analysis: SF6 leak detector can be generally divided into qualitative leak detector and quantitative leak detector, qualitative leak detector is generally low accuracy, easy to carry, cheap; The quantitative leak detector is often used in places with high precision and high frequency of use. The principle of these products is roughly the same, mostly using the corona principle of negative polarity capture, its basic working mode is in the detector hose head there is a micro sensor, the sensor is made of an alloy material, at work can produce about 2000v micro current high voltage, entering the hose end of fluorine molecules in the high pressure state to produce different electrical signals, different concentrations. The strength of the electrical signal is different. At present, there are many varieties of quantitative leak detectors on the market, which can be divided into high-frequency magnetic field ionization, infrared, laser, electron capture detector (ECD), laser light-sound detection principle, and negative ion capture according to the principle.

Analysis of the current situation of leakage detection in China: According to the relevant regulations of the safety management of the State grid industry, the relevant power bureau of the State Grid has carried out real-time online monitoring of SF6 leakage in most of its subordinate SF6 substations since 2000, in order to ensure the personal safety of entering the substation environment, and also facilitate the diagnosis of the severity of leakage of each air compartment. However, up to now, due to the different applications of each substation project and the existence of equipment from different manufacturers, there are great differences in technical principles and technical levels. In addition, usually for testing equipment, the state has relevant standards, the general verification cycle should not exceed two years. Therefore, in order to effectively improve the level of substation safety management, to curb the occurrence of safety accidents. It is necessary to systematically and conveniently conduct a full range of verification, maintenance and maintenance of SF6 leakage monitoring equipment put into operation within the jurisdiction.
