Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, and particularly relates to a low-voltage feeder cabinet. Background Art

[0002] A low-voltage feeder cabinet is a device used to distribute the incoming main line of strong electricity or weak electricity to each terminal. After the electrical components installed in the low-voltage feeder cabinet work with power on for a long time, a large amount of heat will be generated. If the heat is not dissipated in time, it is easy to cause equipment failures. However, the heating conditions of each part in the low-voltage feeder cabinet are not the same. The severely heated area will transfer heat to other areas, resulting in the need to dissipate heat from the entire interior of the low-voltage feeder cabinet.

[0003] For example, Chinese Patent No. CN219226939U discloses an independently cooled low-voltage feeder cabinet, including a main cabinet body. A bottom cabinet body is fixedly arranged at the lower end of the main cabinet body, and legs are fixedly arranged at the four corners of the lower end of the bottom cabinet body; A blower and an air suction fan are installed in the bottom cabinet body. The outlet of the blower is communicated with an air supply duct, and the inlet of the air suction fan is communicated with an air suction duct. Both the air supply duct and the air suction duct extend into the main cabinet body. By the operation of the blower, air can be sent into the main cabinet body, and by the operation of the air suction fan, the hot air in the main cabinet body can be sucked out of the main cabinet body, so as to realize the internal and external exchange of air in the main cabinet body and play a role in cooling the main cabinet body; A dehumidification structure can be detachably installed in both the air inlet hood and the air outlet hood. By the dehumidification structure, water vapor in the air can be adsorbed. When encountering humid weather, it can prevent the water vapor contained in the external air from entering the main cabinet body and affecting the normal use of the electrical components in the main cabinet body.

[0004] For the low-voltage feeder cabinet involved in the above patent, its interior is not partitioned. The severely heated area will transfer heat to other areas, resulting in the need to dissipate heat from the entire interior of the low-voltage feeder cabinet. Therefore, we need to propose a low-voltage feeder cabinet. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 5 , the present utility model provides a low-voltage feeder cabinet, including a low-voltage feeder cabinet body 1. A partition grid 2 is fixedly installed in the inner cavity of the low-voltage feeder cabinet body 1. The partition grid 2 divides the interior of the low-voltage feeder cabinet body 1 into several groups of independent areas. A cabinet door 3 is hinged to the front of the low-voltage feeder cabinet body 1. A handle 4 is fixedly installed on the surface of the cabinet door 3. Several groups of temperature sensors 5 are fixedly installed on the back of the cabinet door 3, and each group of temperature sensors 5 corresponds to the corresponding independent area separated by the partition grid 2.

[0024] In this embodiment, the interior of the low-voltage feeder cabinet body 1 is divided into multiple groups of independent areas by the partition grid 2. In this way, for the areas with relatively serious heat generation, the heat will not spread to other areas. The user only needs to focus on cooling the areas with relatively serious heat generation. In this embodiment, several groups of temperature sensors 5 are installed on the back of the cabinet door 3, and each group of temperature sensors 5 corresponds to an independent area, which can monitor the temperature of each area separately. Through the setting of this device, the problem that the part with serious heat generation areas will transfer heat to other areas, resulting in the need to cool the entire interior of the low-voltage feeder cabinet body 1, is solved.

[0025] In this embodiment, a cabinet door 3 is hinged to the front of the mortgaged feeder cabinet body 1. When the cabinet door 3 is closed, the cabinet door 3 can protect the electrical components inside the low-voltage feeder cabinet body 1. Through the setting of the handle 4, it is convenient for the user to open or close the cabinet door 3.

[0026] Preferably, each independent area is provided with an independent heat dissipation component.

A filter plate 9 is fixedly installed in the inner cavity of the heat dissipation slot 8. An air intake component for sucking external air into the low-voltage feeder cabinet body 1 and supplying it to the heat dissipation component is installed on the top of the low-voltage feeder cabinet body 1. The air intake component includes a fan 10 fixedly installed on the top of the low-voltage feeder cabinet body 1. The exhaust end of the fan 10 is connected to a connecting pipe 11. One end of the connecting pipe 11 away from the fan 10 is communicated with a connecting branch pipe 12. The bottom end of the connecting branch pipe 12 penetrates through the low-voltage feeder cabinet body 1 and is connected to the heat dissipation shell 6. A control valve 13 is fixedly connected to the surface of the connecting branch pipe 12. One side of the control valve 13 is connected to an air outlet nozzle 14. Both the control valve 13 and the air outlet nozzle 14 are arranged in the inner cavity of the heat dissipation shell 6.

[0027] Through the combined use of the air intake component and the heat dissipation component, when the temperature in a certain area is too high and heat dissipation is required, the user can open the fan 10 and the corresponding control valve 13. The operation of the fan 10 can suck the relatively low-temperature external air, and inject the air into the corresponding heat dissipation shell 6 through the connecting pipe 11, the connecting branch pipe 12, the corresponding control valve 13 and the air outlet nozzle 14, and spray it into the low-voltage feeder cabinet body 1 through the air outlet holes 7 to perform heat dissipation treatment on this area. The relatively high-temperature air can be discharged to the outside through the heat dissipation slots 8. Through the setting of the filter plate 9, it can prevent external dust or sundries from entering the low-voltage feeder cabinet body 1 through the heat dissipation slots 8.

[0028] Wherein, a through hole 15 is provided on the surface of the partition grid 2 and at the corresponding position of the connecting branch pipe 12.

Through the setting of the through hole 15, an installation space can be provided for the connecting branch pipe 12, and the connecting branch pipe 12 can pass through the partition grid 2 through the through hole 15 and be connected to the heat dissipation shell 6.

[0029] It should be noted that a filter component for filtering the sucked air is provided at the air intake end of the air intake component. The air intake end of the fan 10 is connected to the filter component. The filter component includes a filter shell 16 fixedly installed on the top of the low-voltage feeder cabinet body 1. The air intake end of the fan 10 is communicated with the surface of the filter shell 16. A filter net 17 is fixedly installed in the inner cavity of the filter shell 16.

[0030] In this embodiment, through the setting of the filtering component, the air drawn into the interior of the low-voltage feeder cabinet body 1 can be filtered to prevent external air from entering the interior of the low-voltage feeder cabinet body 1 and adhering to the electrical components inside, causing internal short-circuit problems. The dust or debris carried in the air is filtered and intercepted by the filter screen 17. Through the setting of the filter housing 16, the use position of the filter screen 17 can be installed and fixed so that it is located at the air inlet end of the fan 10.
