Maintenance Of 35kv Gas Insulated Switchgear

Although the 35kV gas insulated switchgear has the characteristics of high reliability, long-term stable operation, and is not easily affected by the outside world, after purchasing this kind of product, it will undergo strict quality inspection before leaving the factory, and professional technicians will conduct debugging after installation. This does not mean that inspection and maintenance can be permanently omitted after initial installation and commissioning. In order to prolong the service life of the 35kV gas insulated switchgeart as much as possible to achieve the theoretical design life, it is necessary to regularly check and adjust the equipment during daily use, so as to prevent the equipment from ending its use prematurely and avoid other accidents. So in order to achieve the optimal state of use, what should be done or paid attention to in the daily inspection and maintenance of the 35kV gas insulated switchgear?

Depending on the season and geographical location, focus on the possible impact of different environmental factors. For example, in spring, in outdoor areas, you should pay attention to whether there are birds nesting above the 35kV gas insulated switchgear, so as to avoid bird activities contaminating the outer box, which will lead to short circuit and other problems. In areas with abundant rain in summer, pay attention to the exploration of the soil structure around the 35kV gas insulated switchgear. If there is a potential geological disaster, start the emergency plan in time to protect the equipment from possible dangers such as inclination, landslide, rockfall, etc., and avoid sudden accidents. Affect the living and work electricity consumption of surrounding residents. At the same time, attention should be paid to cleaning up water vapor and recording the humidity level in the cabinet. Excessive humidity may also cause danger.

Conduct live testing on internal components on a regular basis. The data of each inspection should be recorded. If abnormality is found, it should be reported and replaced in time, so as not to cause more serious consequences due to the backlog of problems.

In addition, the SF6 barometer also needs to be checked regularly. When the pointer of the pressure gauge is not in the green area, it is necessary to check the leak in time to find out the cause of the abnormal pressure in the gauge, and replenish the gas in time.

The above are the special circumstances that need to be paid attention to. In order to prolong the service life of the 35kV ring main unit, the daily maintenance should be done. These works can also be applied to other types of inflatable ring main units.
