Anti-condensation device and method for box-type equipment

Abstract

The invention discloses an anti-condensation device for box-type equipment, and the device comprises: a cabinet body, wherein the inner wall of the upper part of the cabinet body is provided with a super-hydrophobic coating; a drainage assembly which is detachably installed in the cabinet body, wherein the drainage assembly is located under the super-hydrophobic coating, and the length of the upper portion of the drainage assembly is smaller than the width of the cabinet body so that the interior of the cabinet body can be communicated, wherein the upper portion of the drainage assembly is obliquely arranged downwards in the direction from one side of the cabinet body to the other opposite side of the cabinet body, and the lower portion of the drainage assembly partially extends out of thecabinet body. By arranging the super-hydrophobic coating and the drainage assembly, a part of humidity in the cabinet body can be reduced, so that the working time of later dehumidification is effectively shortened, and the effects of reducing energy consumption and remarkably improving the dehumidification efficiency are achieved; through combination of super-hydrophobic coating dehumidificationand heating ventilation dehumidification, a multi-stage dehumidification effect is achieved, so that the humidity in the box-type equipment cabinet can be effectively reduced, and an excellent anti-condensation effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of anti-condensation for electric equipment, and in particular relates to an anti-condensation device and method for box-type equipment. Background technique [0002] Modern power systems have higher and higher requirements for power supply safety and reliability. Box-type electrical equipment such as ring network cabinets, switch cabinets, box-type substations, and cable branch boxes are the core components of the power system, and their safe and stable operation is the key to power supply. The basis for safe and reliable power supply of the system. However, these box-type equipment generally have the problem of condensation caused by the decrease of the external temperature and the high humidity inside the cabinet, and there is also the possibility of condensation adhesion in the structure of each component inside the cabinet of the box-type equipment. [0003] Condensation phenomenon refers to the conden...

Problems solved by technology

[0005] The dehumidifier dehumidification method absorbs moisture in the air through solid or liquid hygroscopic agents to reduce the air humidity to achieve the purpose of anti-condensation, but there is a problem of aging and failure of the hygroscopic agent, which requires frequent replacement, which increases the workload and cannot accurately control the air humidity.

[0006] The condensation dehumidification method uses refrigeration equipment to cool the air temperature below the dew point temperature, so that the water vapor in the air is liquefied into water droplets, which are discharged through the water pipe, thereby reducing the air humidity in the cabinet to achieve the purpose of anti-condensation, but this method has equipment Constitute complex, costly and energy-intensive problems

[0007] The heating dehumidification method uses air heaters and other equipment to heat the air in the cabinet, the air temperature in the cabinet rises, the moisture changes from liquid to gaseous, and is discharged through ventilation, thereby reducing the air humidity in the cabinet and achieving the effect of anti-condensation. Compared with the above two methods, this method is easy to maintain, simple in equipment and low in energy consumption. It is widely used in practice, but the anti-condensation effect cannot meet the requirements.
