[0002] The technology of power distribution cabinet is an important field in the power system. The power distribution cabinet is usually composed of a cabinet, circuit breaker, disconnector, mutual inductor, electric meter, etc. The cabinet is the basis of the power distribution cabinet, which is used to install electrical components and protect the inside of the equipment. The electrical principle of the power distribution cabinet mainly involves the measurement and control of parameters such as current, voltage, power factor, etc. By using mutual inductors, ammeters, voltmeters and other equipment, these electrical parameters can be monitored in real time, and adjusted and controlled as needed. In power engineering, the application of power distribution cabinets is very extensive. They are installed in various power facilities, such as substations, power plants, industrial plants, etc., to distribute electrical energy to various electrical equipment. At the same time, the power distribution cabinet also undertakes important tasks such as protecting circuits and preventing the spread of electrical faults.

Put the quicklime wrapped in a cloth bag on the ventilation partition 706 and the pull-out box The inner surface of 707, the ventilation plate 703 and the ventilation holes 710 at the bottom of the pull-out box 707 increase the contact area between the quicklime and the air, thereby accelerating the dehumidification efficiency. After the quicklime reacts completely with the moisture in the air, the handle 705 can be pulled open to replace the quicklime on the ventilation baffle 706. The quicklime inside the pull-out box 707 is pulled out of the pull-out box 707 to the top of the rectangular groove 708 for replacement through the circular handle 711. When the fan blade 609 rotates to generate airflow, the motor 902 starts to work, driving the active gear 904 to rotate, and the active gear 904 engages with the driven gear 907 to drive the driven gear 907 to rotate. The wind guide plate 1 905 and the wind guide plate 2 908 rotate at the same time, directing the wind to the direction of the rectangular hole 5, accelerating the internal air circulation, and cooperating with the fan blade 609 takes the heat generated by the power element away from the inside of the cabinet 1. When the fan blade 609 stops working, the motor 902 rotates in the opposite direction, returning the air guide plate 1 905 and the air guide plate 2 908 to their initial state, perpendicular to the rectangular hole 2 8, to maintain air circulation inside the cabinet 1, accelerate the reaction of quicklime with moisture in the air inside the cabinet 1, and keep the internal air dry. When the humidity of the external environment is too high, the drive shaft of the servo motor 914 rotates to drive the threaded rod 917 to rotate, and the slider 919 is restricted from rotating by the limit rod 918. The spiral groove of the threaded rod 917 interacts with the internal thread of the slider 919, so that the slider 919 drives the folding fan 921 to move linearly downward to the bottom position of the rectangular groove 3 922, closing the rectangular hole 2 8 to prevent external moisture from entering the cabinet 1.
