Description

Technical Field

[0001] The utility model relates to the technical field of dehumidification of distribution boxes, in particular to a dehumidification device for distribution boxes. Background Art

[0002] The distribution box is a total circuit distribution box for all users. It is a low-voltage distribution device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements. When the distribution box is in a basement, outdoors or other humid environments, the requirements for dehumidification inside the distribution box become extremely special. During the long-term operation of the distribution box, it is easily affected by the external environment, causing the humidity of the air inside it to increase. The humid air can easily cause short circuits in its internal electrical components.

[0003] For example, the Chinese patent with publication number CN210224709U proposes a dehumidification device for a distribution box, which includes a distribution box, a dehumidification box is fixedly installed on the top surface of the distribution box, a bearing is fixedly installed on the middle end of the top of the dehumidification box, a follower rod is installed through the inner wall of the bearing, and a follower gear is embedded on the top surface of the follower rod. Since a blower fan blade is installed on the surface of the follower rod, the follower rod can be driven to rotate by rotating the motor, thereby driving the blower fan blade to rotate, and a heating rod is installed at the horizontal position at the bottom end of the blower fan blade, which can be driven by The rotation of the fan blades generates a downward airflow, which quickly transports the heat generated on the surface of the heating rod to the inside of the distribution box, thereby heating and dehumidifying the inside of the distribution box. The heated evaporated moisture flows to the inside of the drainage box under the drive of the downward airflow, thereby ensuring the dryness of the inside of the distribution box. This is more practical and suitable for wide promotion and use. However, in the actual application of this scheme, the heat generated during heating can easily cause the temperature inside the box to rise. Excessive temperature is not conducive to the service life of the electrical components in the box. In order to solve the above problems, we have proposed a dehumidification device for a distribution box. Utility Model Content
