Self-breathing outdoor power distribution cabinet and use method thereof

Abstract

The invention relates to the technical field of power distribution cabinets, and discloses a self-breathing outdoor power distribution cabinet. The cabinet comprises a base, a water tank and a water pump, the base is fixedly connected with the ground, a center shaft is movably installed in the center of the interior of the base, a turbine is fixedly connected to the center shaft in a sleeving mode, and a worm is movably installed on the right portion of the base. Through the arrangement of an outer sleeve and an inner sleeve, an installation frame and components on the installation frame are sealed, so external interference is reduced; meanwhile, through the arrangement of a buoyancy device, when the outer sleeve is affected by external high temperature, water in the outer sleeve is heated, then air in the buoyancy device is heated to expand, the water is squeezed out, and water in the outer sleeve is discharged outwards from a water outlet hole, then is restrained by a side baffle plate and slowly flows down from the outer side wall of the outer sleeve, so that a large amount of heat is taken away by utilizing evaporation of the water, the outer wall of the outer sleeve is rapidly cooled, and the influence of external high temperature on components in the power distribution cabinet is avoided.

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a self-breathing outdoor power distribution cabinet and a method for using the same. Background technique [0002] There are a large number of power and communication equipment inside the power distribution cabinet, such as fuses, contactors, frequency converters and other components. When the outdoor temperature is too high, these components will also generate a large amount of The heat, especially the products with frequency converters, generates more heat, which can easily make the internal temperature of the power distribution cabinet reach more than 40 degrees. At the same time, some components are very sensitive to high temperature. Once the internal temperature of the power distribution cabinet When the temperature is higher than 40 degrees for a long time, it will seriously affect the stability and service life of the power distribution equipment.

Problems solved by technology

[0002] There are a large number of power and communication equipment inside the power distribution cabinet, such as fuses, contactors, frequency converters and other components. When the outdoor temperature is too high, these components will also generate a large amount of The heat, especially the products with frequency converters, generates more heat, which can easily make the internal temperature of the power distribution cabinet reach more than 40 degrees. At the same time, some components are very sensitive to high temperature. Once the internal temperature of the power distribution cabinet When the temperature is higher than 40 degrees for a long time, it will seriously affect the stability and service life of the power distribution equipment. It will also cause the components to catch fire and cause a fire. Therefore, it is necessary to conduct deep heat dissipation for the power distribution cabinet. However, there are some shortcomings in the heat dissipation currently used, as follows:

[0003] First, some unsealed cabinets use natural wind for internal cooling, but the natural wind will inevitably carry some dust into the power distribution cabinet and enter the interior of the components, which will affect the internal operation of the components, and The oxygen in the air is heated to accelerate the oxidation of some rubber products in the components, thereby accelerating its aging speed and affecting the use speed of components

[0004] Second, the power distribution cabinets used outdoors are generally sealed, but air conditioners or heat exchangers are generally installed for internal heat dissipation. When the two are running, they not only need to consume a lot of energy, but also need to inhale air from the outside. Air, so that oxygen enters the power distribution cabinet, causing components to age

[0005] Third, the existing power distribution cabinets generally adopt a single-door type. As a result, it is very inconvenient to install components and maintain and repair later, and it is impossible to comprehensively and intuitively check and repair each component and the connecting wires between components. maintenance difficulty
