Description

Technical Field

[0001] The utility model relates to the technical field of nursing equipment, in particular to a grid-connected cabinet for a wind energy converter. Background Technique

[0002] A wind power converter usually consists of three cabinets, namely a grid-connected cabinet, a control cabinet, and a power cabinet. The grid-connected cabinet is used to connect the generator system and the power grid system. The grid-connected cabinet is equipped with complete grid connection and protection devices, which play the role of grid-connected power generation for the generator.

[0003] When the existing grid-connected cabinet of the converter is in use, the heat dissipation of the grid-connected cabinet only relies on the blower to blow air for heat dissipation. The blown air is at room temperature, so the heat dissipation effect of the blown air on the electrical components inside the grid-connected cabinet cannot be guaranteed. At the same time, the air distribution effect inside the existing grid-connected cabinet cannot be guaranteed, so that the low-temperature air cannot be evenly blown into the inner side of the cabinet, affecting the heat dissipation effect. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a grid-connected cabinet for a wind energy converter. By setting an air compressor, an air delivery pipe, an air inlet box, a vortex tube, and an air filter element, the air compressor sends compressed air into the vortex tube through the air delivery pipe. The air blown into the air inlet box from the lower end of the vortex tube has a lower temperature. The low-temperature air enters the cabinet after being filtered by the air filter element, and then effectively cools and dissipates heat from the electrical components inside the cabinet, ensuring the heat dissipation effect of the electrical components, and effectively solving the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A grid-connected cabinet for a wind energy converter, including a cabinet body. On one side surface of the outer part of the cabinet body, an air inlet box is installed. On the upper part of the air inlet box, a vortex tube is installed. The upper end of the vortex tube is connected with an air outlet pipe. On one side of the lower part of the vortex tube, an air delivery pipe is connected. At the end of the air delivery pipe far away from the vortex tube, an air compressor is installed. On the bottom side inside the air inlet box, an air filter element is installed. On the bottom side inside the cabinet body, an air distribution box is installed. On the upper side of the air distribution box, an air outlet baffle is installed.

[0006] Further, on one side surface of the upper part of the cabinet body far away from the air inlet box, a heat dissipation filter screen is installed. One side surface of the cabinet body is connected with a cabinet door through a hinge. On the inner side surface of the cabinet body, a mounting rack is installed.

[0007] Further, the mounting rack is connected with the cabinet body through bolts. The heat dissipation filter screen is connected with the cabinet body through a card slot. The air inlet box is connected with the cabinet body through bolts.

[0008] Further, the air filter element is connected with the air inlet box through a card slot. The air inlet box is connected with the air distribution box through bolts.

[0009] Further, the vortex tube is threadedly connected to the air inlet box, and the upper end of the vortex tube is flange-connected to the air outlet pipe.

[0010] Further, the air supply pipe is flange-connected to the vortex tube, and the air supply pipe is threadedly connected to the air compressor.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. Through the air compressor, air supply pipe, air inlet box, vortex tube and air filter element provided by the present utility model, the air compressor sends compressed air into the vortex tube through the air supply pipe. The air blown into the air inlet box at the lower end of the vortex tube has a lower temperature. The low-temperature air enters the cabinet after being filtered by the air filter element, thereby effectively air-cooling and dissipating heat from the electrical components in the cabinet, ensuring the heat dissipation effect of the electrical components.

[0013] 2. Through the air distribution box and air outlet baffle provided by the present utility model, after the high-pressure air in the air inlet box is blown into the air distribution box, the air outlet baffle is blown into a vertical open state, enabling the air distribution box to evenly blow out the low-temperature air, thereby ensuring the heat dissipation effect of the electrical components in the cabinet.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3, this embodiment provides a technical solution: a wind energy converter grid connection cabinet, including a cabinet body 1, an air inlet box 6 is installed on one side of the outer part of the cabinet body 1, an eddy current tube 5 is installed on the upper part of the air inlet box 6, an air outlet pipe 3 is connected to the upper end of the eddy current tube 5, a air supply pipe 4 is connected to one side of the lower part of the eddy current tube 5, an air compressor 7 is installed at one end of the air supply pipe 4 away from the eddy current tube 5, an air filter element 10 is installed on the inner bottom side of the air inlet box 6, a air distribution box 11 is installed on the inner bottom side of the cabinet body 1, and an air outlet baffle 12 is installed on the upper side of the air distribution box 11.

[0020] As Figures 1-3 shown, the high-pressure gas sent into the air distribution box 11 from the air inlet box 6 can blow the air outlet baffle 12 into a vertical state, so that the low-temperature air blown out by the air distribution box 11 is evenly sent into the inner side of the cabinet body 1, ensuring the heat dissipation effect of the electrical components inside the cabinet body 1. The air filter element 10 can filter the high-pressure gas blown into the inner side of the air inlet box 6 to prevent sundries from entering the inner side of the cabinet body 1.

The air blown out from the upper end of the vortex tube 5 has a higher temperature, and the air blown out from the lower end of the vortex tube 5 has a lower temperature. After the low-temperature air enters the air inlet box 6, it is filtered by the air filter element 10 and then enters the air distribution box 11. After uniform air distribution, it is blown into the inner side of the cabinet body 1, so that the electrical components in the cabinet body 1 are evenly cooled. The high-pressure gas sent from the air inlet box 6 into the air distribution box 11 can blow the air outlet baffle 12 into a vertical state, and then make the low-temperature air blown out from the air distribution box 11 evenly sent into the inner side of the cabinet body 1, ensuring the heat dissipation effect of the electrical components on the inner side of the cabinet body 1.
