[0002] The large-scale power system that emerged in the 20th century is one of the most important achievements in the history of human engineering science. It is a power production and consumption system composed of power generation, transmission, transformation, distribution and power consumption. It converts primary energy in nature into electricity through mechanical energy devices, and then supplies electricity to various users through transmission, transformation and distribution. In the application of power technology, busbars are often used to transmit electricity. When using busbars for transmission, the busbars need to be connected to the transmission equipment. Among them, the common box enclosed busbar can meet the requirements of rainproof, fogproof and dripproof whether installed indoors or outdoors.

[0004] There are still certain deficiencies in the above-mentioned related technologies. For example, when the high-voltage enclosed bus is used in an environment with low humidity, a mobile hot air blower is used in conjunction with an air supply pipe to supply hot air to the bus duct shell, thereby drying the moisture in the bus duct shell. This causes the bus to be in a high-temperature hot air environment, which makes it prone to aging and has a short service life. Therefore, in order to solve such problems, we propose a common-box enclosed busbar with a dehumidification structure. Utility Model Content
