Maintenance and upkeep of 35kV gas-insulated switchgear
Although the 35kV gas-insulated switchgear has characteristics such as high reliability, long-term stable operation, and resistance to external influences, it will undergo strict quality inspection before leaving the factory after purchasing this type of product. After installation, professional technicians will carry out debugging, but this does not mean that it can be permanently left unchecked and unmaintained after the initial installation and debugging. To extend the service life of the 35kV gas-insulated switchgear as much as possible to reach its theoretical design life, regular inspections and adjustments of the equipment are required during daily use. This not only prevents the equipment from ending its service prematurely but also avoids triggering other accidents. So, to achieve optimal operating conditions, what tasks should be done or focused on during the daily inspection and maintenance of the 35kV gas-insulated switchgear?
Depending on the season and geographical location, focus on the potential impacts of different environmental factors. For example, in spring, in outdoor areas, attention should be paid to whether there are birds nesting above the 35kV gas-insulated switchgear to avoid bird activities contaminating the outer casing, which could lead to short circuits and other issues. In summer, in areas with abundant rainfall, pay attention to the soil structure around the 35kV gas-insulated switchgear. If there are potential geological hazards, activate emergency plans in a timely manner to protect the equipment from possible dangers such as tilting, landslides, and falling rocks, avoiding sudden accidents that could affect the lives and work of nearby residents. Additionally, attention should be paid to clearing water vapor and recording the humidity levels inside the cabinet, as excessive humidity may also pose risks.
Regularly conduct live testing of internal components. Each test's data should be recorded, and if abnormalities are found, report and replace components in a timely manner to avoid accumulating problems that could lead to more serious consequences.
In addition, the SF6 pressure gauge also needs to be checked regularly. When the pressure gauge pointer is not in the green zone, it is necessary to promptly check for leaks to identify the cause of the abnormal pressure and replenish gas in a timely manner.
The above are some special situations that need to be focused on for the daily maintenance of the 35kV ring network cabinet to extend its service life. These tasks can also be applied to other types of gas-insulated ring network cabinets.
