Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of moisture-proofing of the bottom of a switch cabinet, in particular to a moisture-proofing device for the bottom of a high- and low-voltage switch cabinet. Background Art
[0002] High and low voltage switchgear is a cabinet that aggregates components and is used in environments and places where electrical appliances and lines are required. Different power systems are installed inside the switchgear, such as disconnectors, circuit breakers and commutation switches. Their function is to protect the components installed inside and to convert power transmission and distribution.
[0003] High and low voltage switchgear is placed on the ground. Generally, in order to prevent the bottom of the cabinet from directly contacting the ground, support feet are added at the lower end. However, during the rainy season in the Jiangnan region, the air in the entire environment is humid, resulting in more water vapor in the cabinet and water accumulation at the bottom of the cabinet. This can easily cause rust between the internal connecting wires and components, resulting in poor contact or short circuit, which in turn affects the use of the entire circuit. Utility Model Content

[0016] Preferably, slots are fixed on the inner walls at both ends of the shell, and the humidity sensor is placed in one of the slots, and a controller is placed in the other slot, and the fan and the humidity sensor are both electrically connected to the controller.
[0017] The humidity sensor and controller are placed in two slots respectively. As the moisture-absorbing cotton absorbs the moisture in the switch cabinet, when the humidity sensor detects that the humidity in the shell is too high, the fan blows air into the shell to discharge the moisture from the switch cabinet.
[0018] The beneficial effects of the utility model are:
[0019] The moisture-absorbing cotton absorbs moisture in the switch cabinet in daily life. When the moisture-absorbing cotton is fully absorbed by the moisture, the humidity sensor detects that the humidity in the shell is too high and transmits the signal to the controller.
