Abstract

The invention discloses a switch cabinet condensation prevention intelligent detection and control system comprising a cabinet body. The outer surface of the cabinet body is provided with a heat preservation layer. The inner wall of the cabinet body is provided with a condensation generation mechanism. The inner wall of the cabinet body is provided with a first temperature sensor. The cabinet bodyis internally provided with a dew point instrument which is used for detecting the inner air dew point temperature. The outer surface of the electrical equipment in the cabinet body is provided witha second temperature sensor. The cabinet body is internally provided with a drying mechanism which is used for drying the electrical equipment. The cabinet body is internally provided with a PLC. Thecold iron bars of which the temperature is lower than that of the surface of the electrical equipment in the switch cabinet can be provided and the condensation phenomenon is enabled to occur on the surface of the cold iron bars by priority and the condensed drops of water drops into the container filled with the desiccant along the cold iron bars so that the probability of condensation on the electrical equipment in the switch cabinet can be greatly reduced; besides, the electrical equipment can be dried by using the drying mechanism in the cabinet body so as to further avoid the condensationphenomenon on the electrical equipment.

Description

technical field [0001] The invention relates to the field of anti-condensation technology for lighting cabinets, in particular to an intelligent detection and control system for anti-condensation of switch cabinets. Background technique [0002] The switchgear is a very important electrical equipment in the power system. In the power system, the switchgear is responsible for the dual functions of closing and disconnecting the power line and protecting the safety of the system. With the rapid development of electric power towards high voltage, large units, and large capacity, the growing power grid and the popularization and promotion of substation unattended management mode and comprehensive automation, the safe operation of switchgear is becoming more and more important, and the modern power system has a great impact on power quality. The requirements are getting higher and higher, and correspondingly higher requirements are put forward for the reliability of the switchgear...
