As an important part of the ring main unit, the operating mechanism will affect the working performance of the equipment and personal safety. Therefore, the stability of the operating mechanism is particularly important. However, in the southern region, the air humidity is high. The operating mechanism is in a high humidity environment for a long time. The parts will inevitably rust and oxidize. If it needs to be operated at this time, an accident is likely to occur. In addition, in extremely harsh environments, such as highly polluted areas, coastal areas, or flood disasters, the performance and life of the operating mechanism will be seriously affected. Therefore, it is necessary to design a fully enclosed operating mechanism that can cope with various complex and harsh working environments. Summary of the invention
