Description

Technical Field

[0002] Electricity is indispensable to human daily life and work, which is one of the major characteristics of human activities in the new century.

[0003] Therefore, ensuring the safety of power supply and electricity use has always been of great concern to the power sector and industrial and mining enterprises. More than 99% of the electrical equipment widely distributed in the power distribution line, such as high and low voltage switchgear, ring network cabinets, switchgear, box transformers, secondary panel cabinets, etc., use air insulation.

[0004] In the early stages of catastrophic failures of these electrical equipment, the gas state in their relatively closed electrical environment will inevitably change accordingly. For example, overheating and smoldering will produce smoke particles, which will increase the air's light-blocking properties and CO concentration. Increased humidity will lead to increased air ionization. Electric field concentration, surface discharge, local discharge, etc. will cause air ionization, which will increase ozone concentration, etc.

[0005] At present, domestic and foreign research institutions and power technology companies usually use discharge detection to monitor the insulation performance of electrical equipment. There is no technology and equipment that can accurately monitor and evaluate the status of electrical equipment from the perspective of "power environment gas". Existing gas detection devices are difficult to collect data in real time and collect only a single type of gas, so they cannot provide very early warning of electrical equipment failures. Utility Model Content

[0006] The utility model provides a very early power environment data acquisition device, which solves the problem that the existing gas detection device is difficult to collect data in real time and the type of gas collected is single, and the problem of being unable to achieve very early warning of electrical equipment failure.
