Problems solved by technology

like figure 1 As shown, the traditional ventilation window is a louver structure. Although it can partially play the role of ventilation and protection, only 1 of the louver blades is installed outside the equipment. The louver blade 1 is mainly used for waterproof and insect-proof shelter. The dust cover 2 is not conducive to air circulation

Abstract

The invention relates to an outdoor electrical cabinet which comprises a cabinet body, a cabinet top and a cabinet door, an air inlet is arranged at the bottom of one side wall of the cabinet body, an air outlet is arranged at the top of the opposite side wall of the cabinet body, corrugated sheet type louver ventilating windows are arranged on the air inlet and the air outlet, each corrugated plate type louver ventilating window is formed by a plurality of stacked corrugated sheets, and ventilating channels are formed between adjacent corrugated sheets. A novel ventilating window structure is adopted for guiding hot air to form a ventilating flow, collision, jump, circuity and circling round of air are avoided, buoyancy lift of the air is maintained and improved, the effective ventilating area is increased, and more air is made to enter a range. Air velocity is maintained, through capitalizing on the trend, artificial wind is formed, complete natural ventilation is achieved, ventilating efficiency is improved, the outdoor electrical cabinet is safe, reliable, energy-saving and environment-friendly, and the natural air cooling technology is used for meeting cooling requirements of outdoor electrical equipment.

Description

technical field [0001] The invention relates to an outdoor electrical device, in particular to an outdoor electrical cabinet equipped with ventilation windows, and belongs to the technical field of electrical equipment. Background technique [0002] The temperature rise of electrical equipment has a great impact on its service life and stability. After the conductor is passed through, the current heat effect is generated. As time goes by, the temperature of the conductor surface continues to rise until it becomes stable. The part of the rising temperature that exceeds the temperature of the surrounding air (environmental temperature) is called temperature rise. The temperature rise of the equipment There are many factors, mainly including: heating of electrical components, heating of electrical busbars, heating of electrical contacts, heating caused by electromagnetic eddy currents, etc. At present, the conventional cooling methods for electrical equipment are generally nat...
