The cabinet door 230 of the power distribution cabinet 200 rotates relative to the cabinet body 210 under the action of external force, and when the opening 217 of the main body 211 is opened or closed, the filtering bracket 214 can be driven to move relative to the cabinet body 210 through the linkage assembly 250; that is, when the cabinet door 230 rotates to the position of opening 217 relative to the main body 211 under the action of external force, the linkage assembly 250 drives the filter holder 214 to move to the second position relative to the chute 218, and at this time, the first filter plate 242 connected to the filter holder 214 synchronously moves to the outside of the connection between the air inlet duct 213 and the main body 211; when the cabinet door 230 rotates to a position closing the opening 217 relative to the cabinet body 210 under the action of an external force, the linkage assembly 250 drives the filtering bracket 214 to be located at the second position, and at this time, the first filter plate 242 connected with the filtering bracket 214 synchronously moves to the connection position of the air inlet duct 213 and the main body 211. In this way, when the cabinet door 230 is opened, the first filter plate 242 for filtering the airflow conveyed into the installation cavity 215 can be taken out during the installation and maintenance of the power distributor 100 in the power distribution cabinet 200, so that the maintenance of the first filter plate 242 is facilitated.
Therefore, as can be seen from the above, the power distribution cabinet 200 can filter the air flow entering the installation cavity 215 through the first filter plate 242, so as to prevent impurities from entering the installation cavity 215, thereby maintaining the working environment in the installation cavity 215, and after the impurities on the first filter plate 242 are more blocked, the heat can be dissipated through the heat dissipation air duct 216, so as to prevent the air flow mixed with the impurities from entering the installation cavity 215 while ensuring the heat dissipation effect. And, at the in-process of maintaining switch board 200, just can take out first filter plate 242 through opening of cabinet door 230, and then can conveniently observe the user state of first filter plate 242 to maintain it, thereby when guaranteeing this switch board 200's radiating effect, reduce this switch board 200's the maintenance degree of difficulty.
Further, one end of the air inlet duct 213, which is used for being connected with the main body 211, is provided with a notch 263, and the notch 263 and the main body 211 together form a channel for the filter holder 214 to pass through. In the using process, when the cabinet door 230 is opened or closed, the filtering bracket 214 is driven to move, so that the sealing performance of the connection between the air inlet duct 213 and the main body 211 is ensured when the filtering bracket 214 is located at the first position, and therefore, a baffle 264 is arranged on one side of the fixing frame 261 facing the second position, and the baffle 264 is used for being matched with the channel to close the channel when the fixing frame 261 is located at the first position.
In this embodiment, drive link 251 is located within mounting cavity 215. In order to guide the movement of the fixing frame 261 and facilitate the connection with the linkage assembly 250, the main body 211 is provided with a guide groove along the opening path of the sliding groove 218; the fixing frame 261 is provided with a guide protrusion, and the guide protrusion is matched with the guide groove and is used for being hinged with the transmission rod 251.
To improve the heat dissipation effect of the distribution cabinet 200, the distributor mounting bracket 220 is connected to the partition 212 to transfer the heat in the mounting cavity 215 to the heat dissipation air duct 216.
In order to prevent impurities from flowing back into the installation cavity 215 through the exhaust port 219, a second filter plate 266 is disposed at a communication part between the installation cavity 215 and the exhaust port 219.
In order to improve the heat dissipation effect of the heat dissipation air duct 216, the power distribution cabinet 200 includes two partition plates 212, and both the two partition plates 212 are connected to the main body 211 to form the heat dissipation air duct 216 on both sides of the main body 211.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
