In response to the construction requirements of the State Grid Corporation of China for distribution automation, more and more primary and secondary integrated ring network boxes have emerged. The primary and secondary integrated ring network box is a kind of power distribution equipment that integrates the functions of the primary and secondary sides to achieve multiple functions such as power distribution, protection, control and measurement.

[0003] When the ring network box is in use, the electrical equipment inside it will generate heat when working, and the increase in temperature will cause the internal resistance of the electrical equipment to increase, thereby increasing the loss. Therefore, air holes are often opened on the ring network box to exchange heat with the outside world.

[0004] However, when the humidity of the external environment is high, such as around rivers, lakes, or when it rains, the external moisture will enter the ring network box through the air vents, increasing the possibility of short circuit leakage inside the ring network box, affecting the normal operation of the electrical equipment in the ring network box, affecting the service life of the ring network box, and endangering the lives of people around. Summary of the invention
