Abstract

The invention provides an automatic electrical equipment protection screen and cabinet ventilating device. A cabinet door for automatically opening the ventilating device is formed in a protection screen of the automatic electrical equipment protection screen and cabinet ventilating device. The electronic control openable and closable shutter type design is adopted for the cabinet door. When the temperature and humidity in a screen cabinet reach the preset values through the temperature and humidity control, a shutter is started to be opened, a ventilating motor is started, and ventilating and cooling are conducted on a protection device; when the temperature and humidity in the screen cabinet are decreased below the preset values, the ventilating motor is automatically stopped, and the shutter is then automatically closed. The effects of dust prevention, attractiveness and energy conservation are achieved.

Description

Technical field [0001] This set of equipment involves a automatic device that ventilates and cools the screen and cabinets in the safe operation of power, communication and other industries. Background technique [0002] At this stage, most of the protection screen cabinets are widely used at this stage. There are no ventilation devices. They all use the equipment itself to cool the cooling fan. The hot air cannot be discharged from the inside of the screen cabinet. Long -term operation or due to the increase in indoor temperatures.High temperature operation, accelerate the aging of equipment, affect the service life of the equipment, and seriously cause serious consequences of equipment accidents such as overheating and short circuit and fire. Invention content [0003] The purpose of invention: The present invention provides a kind of power equipment protection screen and automatic ventilation device for the cabinet. [0004] Technical solution: The present invention is achiev...
