Description

Technical Field

[0001] The utility model relates to the technical field of power grid operation, and in particular to a power grid operation environment monitoring device. Background Art

[0002] During the operation of the power grid, the gas conditions in the surrounding environment have an important impact on the safe and stable operation of the power grid equipment. For example, places such as substations may cause leakage of gases such as sulfur hexafluoride, and power grids near industrial areas may be corroded by harmful gases such as sulfur dioxide and nitrogen oxides. The existing power grid operation environment gas measurement devices have many shortcomings.

[0003] Most of the existing gas measuring devices are not equipped with an effective filter cleaning structure. In actual operation, dust and impurities in the air will continue to adhere to the filter. Over time, the filter will gradually become clogged, resulting in poor gas circulation and affecting the accuracy and timeliness of gas monitoring. For example, in areas with frequent sandstorms, the filter may be clogged by a large amount of sand and dust in a short period of time, making it impossible for the monitoring device to accurately detect the gas composition and concentration, and unable to promptly detect potential gas leaks or exceeding the standard, posing a hidden danger to the safe operation of power grid equipment.

[0004] Therefore, we make improvements to this and propose a power grid operation environment monitoring device. Utility Model Content
