Sulfur hexafluoride gas leak detection alarm apparatus and working method thereof

Abstract

The invention belongs to the technical field of sulfur hexafluoride detection, and aims to solve problems that internal gas is easy to leak when an existing sulfur hexafluoride gas detection device is disassembled and replaced, the internal leaked gas cannot be treated, the interior cannot be ventilated, and the safety performance is poor. The invention provides a sulfur hexafluoride gas leak detection alarm apparatus and a working method thereof particularly; the sulfur hexafluoride gas leak detection alarm apparatus comprises a detection assembly, the detection assembly is installed on a high-voltage electrical cabinet, a sealing anti-leakage assembly and a rapid fixing assembly are installed in the high-voltage electrical cabinet, a gas processing chamber is formed in a gas processing box, and a gas pumping assembly is arranged on the gas processing box. A uniform gas outlet assembly is mounted in the gas processing chamber; according to the invention, the interior of the high-voltage electrical cabinet can be monitored and specific processing operation can be carried out based on data analysis, the safety and the use effect are remarkably improved, the detection device is convenient to replace, internal gas can be effectively prevented from leaking to the outside, and the safety performance is further improved.

Description

technical field [0001] The invention relates to the technical field of sulfur hexafluoride detection, in particular to a sulfur hexafluoride gas leak detector and alarm device and a working method thereof. Background technique [0002] The density of sulfur hexafluoride gas is about 5 times that of air, and it is gaseous at normal temperature and pressure. The molecular structure is arranged in an octahedron, the bonding distance is small, and the bonding energy is high. Insulation is widely used in many electrical equipment for insulation and arc extinguishing, especially in high-voltage equipment; in high-voltage electrical cabinets, because the equipment is high-voltage equipment, it is necessary to use sulfur hexafluoride gas for arc extinguishing and insulation , to protect the safety of equipment and personnel, but sulfur hexafluoride gas will decompose under the action of electric arc, and the decomposition products include hydrogen sulfide, sulfur dioxide and hydroge...

Problems solved by technology

[0005] The purpose of the present invention is to provide a sulfur hexafluoride gas leak detector and its working method, which can not only monitor the high-voltage electrical cabinet, but also make specific processing operations based on data analysis, which significantly improves the safety and use effect , by setting the fast fixing component, it is convenient to install and disassemble the detection device, and it is helpful for the replacement of the detection device. By setting a sealed anti-leakage component, it can not only effectively prevent the internal gas from leaking to the outside during the disassembly process of the detection component, but also ensure During the normal use of the high-voltage electrical cabinet, the internal gas does not leak to the outside, which further improves the safety performance, and solves the problem that the existing sulfur hexafluoride gas detection device is generally fixed on the high-voltage electrical cabinet, and it is difficult to replace the detection device when it is damaged. It is easy to cause internal gas leakage during disassembly and replacement, and the safety performance is poor, and it only has the function of detecting the concentration of sulfur hexafluoride gas. When the internal gas leaks, it cannot process the gas generated inside and ventilate the inside, further reducing In addition to the safety performance, the use effect needs to be improved
