Embodiment Construction

[0069] Below in conjunction with accompanying drawing of description, the present invention is further described:

[0070] As attached to the manual figure 1 As shown, the present invention electrically connects the circulation fan and the heater in the cabinet.

[0071] The heater adopts electromagnetic heating, infrared heating or resistance heating; it can be selected according to needs, specifically resistance heating adopts one of resistance wire or resistance coil or quartz tube or ceramic tube.

[0072] The circulation fan is one of two-stage axial flow fan, single-stage axial flow fan or centrifugal cooling fan, and the specific size can be selected according to the size of the chassis and the heater.

[0073] For the switch, humidity switch and / or temperature switch can be selected according to requirements.

[0074] For the switch mode, one or more of the push type, seesaw type, toggle type, rotary type, capacitive touch screen type, resistive touch screen type or ...

Abstract

The invention relates to the field of electric control equipment, in particular to a case dehumidification device used in a humid environment. The problem that the electrical equipment is damaged dueto the fact that the case cannot be dehumidified in a humid environment can be solved, automatic or manual dehumidification of the electrical case is achieved, it is guaranteed that air in the case isdry, and the function of the electrical equipment is effectively protected. The case dehumidification device is provided with an air inlet and an air outlet, a filter screen (filter) is arranged at the air inlet, cold air in the atmosphere is sucked in by the fan and heated by a heater, and then hot air with water vapor is sent back to the atmosphere through the air outlet, so that the purpose ofdehumidification is achieved. The dehumidification device is controlled by a humidity switch and/or a temperature switch, an alternating current is automatically selected when the alternating currentexists, a built-in storage battery is automatically selected to supply power when the alternating current does not exist, and uninterrupted dehumidification is achieved. Before the main circuit boardis connected with a power supply, automatic moisture removal or manual moisture removal can be controlled through the PLC, so that circuits and electronic elements in the case are protected from being damaged by moisture.

Description

technical field [0001] The invention relates to the field of electric control equipment, in particular to a chassis dehumidification device used in a humid environment. Background technique [0002] Tunnels are designed in mountains such as high-speed rail tunnels or high-speed tunnels, or designed underground in cities such as subways, which are very humid in such an environment. When the electrical equipment is working, its own temperature can achieve the general tide-repelling effect; but when the electrical equipment is not working or placed in the tunnel for a long time, it is easy to have condensed water or infiltrate water or moisture in the case. When in use, it will cause short-circuit damage due to moisture. Especially for electronic equipment placed in the tunnel, when the electronic equipment is working, the cooling fan brings dust into the chassis, or the dust enters the chassis through the gap of the chassis, and is covered on the circuit board (because the du...
