Problems solved by technology
[0002] At present, the vents on the electrical cabinets adopt a straight-through structure. Due to the large wind and sand in the northwest region, during the long-term use of the outdoor electrical cabinets, a large amount of dust will enter the electrical cabinets, often causing contactors and transfer switches to fail. Serious threat to the safe operation of equipment and power grid

Embodiment Construction
[0009] The present invention will be further described below in conjunction with the drawings.
[0010] Such as figure 1 As shown, the present invention includes an electrical cabinet main body 1 and a ventilation duct 2. The vent pipe 2 has a cross structure. The upper end of the vent pipe 2 is an air inlet 3, and a first filter 4 for air intake is provided in the air inlet 3. The left and right sides of the vent pipe 2 are connected to the main body 1 of the electrical cabinet and connected A second filter screen 5 is provided at the place, and is fixed by a nut 6, and the lower end of the ventilation pipe 2 is closed with a plug 7.
[0011] In the present invention, the gap between the air inlet 3 and the first filter screen 4 forms an air inlet channel, and the second filter screen 5 is installed at the junction of the ventilation pipe 2 and the electrical cabinet body 1, and the entire electrical cabinet body 1 is fixed by a nut 3 A plug 7 is installed on the ventilation pip...

The invention relates to an electric cabinet and particularly relates to a ventilating device for an electric cabinet. The ventilating device for the electric cabinet comprises an electric cabinet body and a ventilating pipe and is characterized in that the ventilating pipe is of a cross-shaped structure, the upper end of the ventilating pipe is provided with an air inlet, a first filter screen for air feeding is arranged in the air inlet, the left and right sides of the ventilating pipe are connected with the electric cabinet body, the joints of the two sides and the electric cabinet body are provided with second filter screens which are fixed by screw nuts, and the lower end of the ventilating pipe is closed. Compared with the prior art, the ventilating device can be used for effectively solving the problem that dust enters the electric cabinet, has a good filtering effect and is easy to clean.
Description
Technical field [0001] The invention relates to an electrical cabinet, in particular to a ventilation device for the electrical cabinet. Background technique [0002] At present, the ventilation openings on the electrical cabinets are all straight-through structures. Due to the large wind and sand in the northwest, a large amount of dust will enter the electrical cabinets during long-term use of outdoor electrical cabinets, which often causes contactors and transfer switches to malfunction. Seriously threaten the safe operation of equipment and power grids. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides a ventilation device for an electrical cabinet. [0004] In order to achieve the above objective, the present invention designs a ventilation device for an electrical cabinet, which includes a main body of the electrical cabinet and a vent pipe. The feature is that the vent pipe has a cross structure, the uppe...
