Temperature adjustment method of power distribution cabinet

Abstract

The invention discloses a power distribution cabinet and a temperature adjustment method thereof. The power distribution cabinet comprises a cabinet body, a temperature adjustment module, a temperature sensor, a micro-control unit, a display module, a communication module and a storage device, wherein the temperature sensor, the micro-control unit, the display module, the communication module and the storage device are arranged in the cabinet body; the temperature sensor, the display module, the temperature adjustment module, the communication module and the storage module are electrically connected with the micro-control unit separately; the temperature sensor comprises a first temperature sensor group, a second temperature sensor group and a third temperature sensor group; the first temperature sensor group is arranged at the position, close to the bottom surface, of the cabinet body; the third temperature sensor group is arranged at the position, close to the top surface, of the cabinet body; the second temperature sensor group is arranged between the first sensor group and the second sensor group; and the display module comprises normal, warming and alarming three-color background lights. According to the power distribution cabinet, the internal temperature can be accurately displayed and measured, the temperature is intelligently adjusted, and the work stability and reliability of the power distribution cabinet are improved.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a power distribution cabinet capable of intelligently adjusting the temperature inside the cabinet and a temperature adjustment method thereof. Background technique [0002] Power distribution cabinets are widely used in power plants, substations, enterprises and other power users. Due to the particularity of their use, the stable operation of power distribution cabinets is an important guarantee to ensure the safety of power users. [0003] During the use of the power distribution cabinet, due to the long-term working conditions of high voltage and high current at the nodes of the internal contacts and cable headers, the junction of the contacts and the connection of the cable are due to surface oxidation, corrosion, and aging of the contacts. Such reasons lead to an increase in resistance, resulting in an increase in temperature and continuous accumulation of heat, which w...

[0003] During the use of the power distribution cabinet, due to the long-term working conditions of high voltage and high current at the nodes of the internal contacts and cable headers, the junction of the contacts and the connection of the cable are due to surface oxidation, corrosion, and aging of the contacts. The resistance increases due to other reasons, resulting in an increase in temperature and continuous accumulation of heat, which will easily lead to a gradual increase in the temperature of electronic components in the power distribution cabinet, resulting in failure of electronic components and affecting the normal operation of the power distribution cabinet.
