Description

Technical Field

[0001] The utility model relates to the technical field of online monitoring devices, in particular to a density micro-water online monitoring device with a gas circulation function. Background Art

[0002] Sulfur hexafluoride high-voltage electrical equipment has been widely used in the power sector, industrial and mining enterprises, and has promoted the rapid development of the power industry. Ensuring the reliable and safe operation of sulfur hexafluoride high-voltage electrical equipment has become one of the important tasks of the power sector. The arc extinguishing medium and insulating medium of sulfur hexafluoride high-voltage electrical equipment are sulfur hexafluoride gas, which cannot leak or exceed the micro-water content. If leakage occurs or the micro-water content exceeds the standard, the reliable and safe operation of sulfur hexafluoride high-voltage electrical equipment cannot be guaranteed. Therefore, it is very necessary to monitor the sulfur hexafluoride gas density and micro-water content of sulfur hexafluoride high-voltage electrical equipment in real time.

[0003] The existing density micro-water online monitoring device cannot realize the circulation of internal gas. The gas micro-water detection is different from the gas pressure detection. In the same gas chamber, the internal pressure is consistent. The density change can be calculated through the change of gas temperature and pressure. However, the micro-water content of the gas in different positions in the same gas chamber is different, and the difference is large. Only by circulating the gas can the micro-water content of the gas be accurately measured. Utility Model Content
