Problems solved by technology
Both the external environment and the temperature in the internal environment of the power distribution cabinet will affect the actual temperature inside the power distribution cabinet. When the internal temperature of the power distribution cabinet is too high, the temperature of the contacts or joints will rise, and the degree of overheating will continue Intensification will affect the insulation performance and equipment life. In addition, due to the sealed structure of the power distribution cabinet, the temperature of the electronic components in the power distribution cabinet will gradually increase. When the temperature is high, the electronic components in the power distribution cabinet will fail, which will make the power distribution cabinet unable to operate normally

The invention discloses a distribution cabinet temperature automatic control system. A cabinet body is divided by a partition board into a first chamber and a second chamber. The partition board is provided with a ventilation hole, and can be in a variety of shapes. The first chamber is provided with ventilation holes in the sidewall and top thereof. A first collection unit is used for collectingthe external temperature T0 of the environment of the cabinet body. A second collection unit is used for collecting the temperature T in the second chamber. A first adjustment unit is used for adjusting the shape of the partition board. A second adjustment unit is used for adjusting the open or closed state of the ventilation holes in the sidewall and top of the first chamber. A cooling unit is used for cooling a distribution cabinet. A control unit makes the first adjustment unit, the second adjustment unit and the cooling unit act through commands based on T0 and T. On one hand, when the outside temperature is too low, protection measures can be taken to prevent the moisture in the cold air from affecting the healthy environment inside the distribution cabinet. On the other hand, when the temperature inside the distribution cabinet is too high, cooling measures can be taken in time to fully guarantee safe use of the distribution cabinet.
Description
technical field [0001] The invention relates to the technical field of temperature control systems, in particular to an automatic temperature control system for a power distribution cabinet. Background technique [0002] The power distribution cabinet is suitable for power users such as power plants, substations, factories, mines, and enterprises. The stable operation of the power distribution cabinet is an important prerequisite to ensure the normal work of power users. One of the important factors affecting the stable operation of the distribution cabinet is temperature. Both the external environment and the temperature in the internal environment of the power distribution cabinet will affect the actual temperature inside the power distribution cabinet. When the internal temperature of the power distribution cabinet is too high, the temperature of the contacts or joints will rise, and the degree of overheating will continue. Intensification will affect the insulation per...
