A cooling and anti-condensation system for an outdoor ring network cabinet and a control method thereof

Abstract

The invention discloses a cooling and anti-condensation system for an outdoor ring network cabinet and a control method thereof, belonging to the technical field of the ring network cabinet. The invention relates to a cooling and anti-condensation system used in an outdoor ring network cabinet and a control method thereof. Through the reasonable arrangement of the inlet and outlet air outlets of the ring-net cabinet, after the pressurization treatment of two blowers with different air inlet directions, the two air currents blown in by the fan intersect in the ring network cabinet. The hot airin the cabinet can be quickly discharged at the upper and lower air outlets to realize the rapid cooling and dehumidification in the ring network cabinet, and meanwhile, the dew point temperature of the air in the ring network cabinet can be reduced to achieve the purpose of anti-condensation in the switch cabinet, so that the air in the ring network cabinet can be dissipated mutually and the airin the ring network cabinet can be dissipated quickly. The continuous pressurization of the fan can make the air pressure in the annular network cabinet appear positive pressure with respect to the atmosphere, so that the air at the gap between the bottom of the annular network cabinet and the cable well can only flow from the top to the bottom, and the humid air from the sealed cable well is prevented from entering the annular network cabinet, thereby achieving the functions of dehumidification and condensation prevention.

Description

technical field [0001] The invention relates to an environment control system and a control method in an outdoor ring network cabinet, and more specifically, to a cooling and anti-condensation system and a control method for an outdoor ring network cabinet. Background technique [0002] Outdoor ring main unit (switchgear) is mainly affected by internal high temperature, humidity and condensation when it is unsheltered. Internal high temperature will cause insulation damage and even cause equipment fires, which will easily reduce the stability of the entire system, or even cause major safety accidents. Condensation and moisture problems will lead to a decrease in internal insulation performance, and various insulation defects will gradually develop into breakdowns and cause accidents. However, the existing methods focus on using external power to solve the heat dissipation, dehumidification and anti-condensation problems of the ring main unit. This method has many factors su...

Problems solved by technology

[0014] The purpose of the present invention is to overcome the shortcomings of the existing outdoor environmental control system in the outdoor ring network cabinet that the efficiency of cooling, dehumidification, and anti-condensation is low, and that it is difficult to simultaneously take into account the three aspects of cooling, dehumidification, and anti-condensation. The cooling and anti-condensation system in the network cabinet and its control method adopt the technical solution of the present invention, through the reasonable arrangement of the air inlet and exhaust outlets of the ring network cabinet, and the interaction of two air inlets with different air inlet directions, the incoming air Through mutual blowing effect, the ring main unit overflows, avoiding the problem of ventilation dead angle, and using two air outlets distributed up and down, the upper air outlet quickly discharges the rising high-temperature air, and the lower air outlet assists in heat dissipation , to achieve rapid cooling and dehumidification in the ring network cabinet, and at the same time achieve the purpose of anti-condensation in the switch cabinet by reducing the dew point temperature of the air in the ring network cabinet; and, using the suction control at the exhaust port, combined with the action of the fan, the exhaust The hot air at the tuyere is quickly discharged, the cooling speed is fast, and the dehumidification effect is good, which effectively prevents condensation inside the ring network cabinet and improves the safety and reliability of the ring network cabinet equipment operation
