Description

Technical Field

[0001] The present invention relates to the technical field of dehumidification for distribution boxes, and more specifically, to a dehumidification device for distribution boxes. Background Art

[0002] Distribution boxes are characterized by small volume, easy installation, special technical performance, fixed position, unique configuration function, unrestricted by site, wide application, stable and reliable operation, high space utilization rate, less floor area and environmental protection effect. They are the control centers for rationally distributing electric energy among various components in the power supply line, the control links for reliably receiving the upper-end power supply and correctly feeding out the load electric energy, and also the key to obtaining whether users are satisfied with the power supply quality. Improving the operation reliability of power distribution boxes is the goal of creating high-quality projects. The uses of distribution boxes are as follows: rationally distributing electric energy, facilitating the opening and closing operations of circuits, having a high safety protection level, being able to intuitively display the conduction state of the circuit. Commonly used distribution boxes are made of wood and metal. Because the metal distribution box has a higher protection level, the metal ones are used more frequently. Classified by structural characteristics and uses, there are fixed panel type switch cabinets, often called switchboards or distribution panels. It is an open-type switch cabinet with a panel shield. It has a protective effect on the front, and the live parts can still be touched on the back and sides. The protection level is low, and it can only be used in industrial and mining enterprises with relatively low requirements for power supply continuity and reliability, for centralized power supply in the substation. The protective (i.e., enclosed) switch cabinet refers to a low-voltage switch cabinet in which all other sides except the installation surface are enclosed. The electrical components such as switches, protection, and monitoring and control in this cabinet are all installed in a closed shell made of steel or insulating material, and can be installed against the wall or away from the wall. There is no need to add isolation measures between each loop in the cabinet, or a grounded metal plate or insulating plate can be used for isolation. Usually, there is a mechanical interlock between the door and the main switch operation. In addition, there is also a protective table type switch cabinet (i.e., control console) with control, measurement, signal and other electrical appliances installed on the panel. The protective switch cabinet is mainly used as a distribution device at the process site. Drawer type switch cabinets. This type of switch cabinet is made of steel plates to form a closed shell, and the electrical components of the incoming and outgoing line circuits are all installed in the extractable drawers, forming a functional unit that can complete a certain type of power supply task. Between the functional unit and the busbar or cable, it is separated by a grounded metal plate or a functional plate made of plastic, forming three areas: the busbar, the functional unit and the cable. There are also isolation measures between each functional unit. The drawer type switch cabinet has high reliability, safety and interchangeability, and is a relatively advanced switch cabinet. Most switch cabinets refer to drawer type switch cabinets. They are applicable to industrial and mining enterprises and high-rise buildings with relatively high requirements for power supply reliability, as centralized control distribution centers. Power and lighting distribution control boxes are mostly vertically installed in a closed manner. Due to different usage occasions, the shell protection levels are also different. They are mainly used as distribution devices at the production sites of industrial and mining enterprises.

[0003] In order to ensure the heat dissipation of the electronic components inside the distribution box, multiple groups of ventilation holes are usually set for ventilation treatment.
