[0002] Neutral point grounding resistor cabinets are divided into transformer neutral point grounding resistor cabinets and generator neutral point grounding resistor cabinets based on the protection object. When the working environment temperature of the resistor cabinet is high, the heat inside the resistor cabinet will further increase. If the temperature is not reduced, the electrical components will be damaged. The existing heat dissipation method is mostly through air cooling.

[0003] According to the Chinese utility model disclosure CN216388921U, an intelligent heat dissipation type generator neutral point grounding resistor cabinet is disclosed, including a main cabinet, a mounting assembly is provided at the lower end of the main cabinet, and a plurality of heat dissipation slots are provided at the lower left end and the lower right end of the main cabinet. In the utility model, a conveying device is provided on the entire device. When in use, the fixed frame is connected to the middle of the upper end of the main cabinet, and the fan is connected to the inside of the fixed frame, and then the rotating column is connected to the output end of the fan, and the fan blades are connected to the lower part of the outer surface of the rotating column. However, the airflow circulation efficiency in the resistor cabinet with this setting is poor, and the heat dissipation efficiency cannot be well improved. Therefore, in view of this problem, how to design a heat dissipation type transformer neutral point grounding resistor cabinet has become a problem that we currently need to solve. Utility Model Content

By arranging an air supply pipe and a branch pipe, the heat dissipation air entering the air supply pipe and the branch pipe finally flows out from multiple side blowing pipes and upper blowing pipes, and the side blowing pipes on both sides are respectively facing the two sides, and the multiple upper blowing pipes are facing upward, so as to facilitate blowing hot air out from the inside of the cabinet, improve air flow, and further accelerate the heat dissipation efficiency to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat-dissipating transformer neutral point grounding resistance cabinet, comprising a cabinet body, an inner cone is fixedly installed on one side of the cabinet body, a protective cover is fixedly installed on one side of the inner cone, a first motor is fixedly installed inside the protective cover, a cooling fan is fixedly installed on the output end of the first motor, the cooling fan is rotatably connected to the inner side of the protective cover, an air duct is connected to one side of the inner cone, a mounting pipe is fixedly installed on the top of the air duct, a filter cotton board is fixedly installed inside the mounting pipe, the number of the filter cotton boards is set to multiple, and the multiple filter cotton boards are evenly distributed in a linear array about the vertical center line of the mounting pipe, an air supply pipe is fixedly installed on the top of the mounting pipe, and a branch pipe is fixedly installed inside the air supply pipe.

[0006] In a preferred embodiment, the outer side of the branch pipe is connected to a side blowing pipe, and the outer side of the air supply pipe is connected to an upper blowing pipe.

[0009] In a preferred embodiment, a connecting rod is fixedly mounted on the bottom of the top cover, and a baffle is fixedly mounted on the outer side of the connecting rod.

[0010] In a preferred embodiment, the baffle is slidably connected to one side of the cabinet, a limit block is fixedly installed on one side of the cabinet, and the connecting rod is slidably connected inside the limit block.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model sets an air delivery pipe and a branch pipe. When heat dissipation is performed, the first motor is started to rotate the heat dissipation fan, thereby generating cooling air that is transported into the interior of the air guide pipe through the inner cone. The heat dissipation air that enters the air delivery pipe and the branch pipe eventually flows out from a plurality of side blowing pipes and an upper blowing pipe, and the side blowing pipes on both sides face the sides respectively, and the plurality of upper blowing pipes face upward, so that the hot air is blown out from the interior of the cabinet, the air flow is improved, and the heat dissipation efficiency is accelerated;

[0013] 2. The utility model provides a top cover and a baffle. When heat dissipation is not performed, the second motor can be started to cause the top cover to descend and fit the cabinet. At the same time, the connecting rod slides downward on the inner side of the limit block, so that the baffles on both sides descend to close the heat dissipation holes on both sides of the cabinet, thereby preventing dust from entering the interior of the cabinet and causing an increase in dust inside the cabinet.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Refer to the instruction manual Figure 1-4 ,like Figure 1 As shown, a heat dissipation transformer neutral point grounding resistor cabinet according to an embodiment of the utility model comprises a cabinet body 1, as shown Figure 2 As shown, an inner cone 5 is fixedly installed on one side of the cabinet 1, a protective cover 2 is fixedly installed on one side of the inner cone 5, a first motor 3 is fixedly installed inside the protective cover 2, a cooling fan 4 is fixedly installed on the output end of the first motor 3, and the cooling fan 4 is rotatably connected to the inner side of the protective cover 2, an air duct 6 is connected to one side of the inner cone 5, a mounting pipe 7 is fixedly installed on the top of the air duct 6, a filter cotton plate 19 is fixedly installed inside the mounting pipe 7, the number of the filter cotton plates 19 is set to be multiple, and the multiple filter cotton plates 19 are evenly distributed in a linear array about the vertical center line of the mounting pipe 7, an air supply pipe 8 is fixedly installed on the top of the mounting pipe 7, a branch pipe 9 is fixedly installed inside the air supply pipe 8, a side blowing pipe 10 is connected to the outside of the branch pipe 9, and an upper blowing pipe 11 is connected to the outside of the air supply pipe 8.

[0021] It should be noted that, when heat dissipation is performed, the first motor 3 is started to rotate the heat dissipation fan 4, thereby generating cooling air that is transported into the interior of the air duct 6 through the inner cone 5, and transported upward through multiple filter cotton plates 19, and multi-layer filtration is performed through multiple filter cotton plates 19, thereby preventing dust and other impurities from entering the air duct 8. The cooling air that enters the air duct 8 will flow into multiple branch pipes 9, and finally flow out from multiple side blowing pipes 10 and upper blowing pipes 11 to dissipate heat inside the cabinet 1, and the side blowing pipes 10 on both sides are respectively facing the two sides, so as to facilitate blowing hot air out of the interior of the cabinet 1 , improve air flow, and thus speed up heat dissipation efficiency. Multiple upper blowing pipes 11 face upward, so that heat can also be dissipated from the top of the cabinet 1, thereby increasing the space for heat outflow. While dissipating heat, the second motor 12 is started to rotate the lifting screw 13 to rotate the internal threaded tube 14 to rise, and drive the top cover 15 to rise, so that the top cover 15 and the cabinet 1 are separated, and the connecting rod 16 is driven up by the top cover 15, thereby causing the baffle 17 to rise, so that the hot air flow can be dissipated from the top and both sides of the cabinet 1, thereby improving the efficiency of airflow in the cabinet 1, thereby improving the heat dissipation efficiency.

[0022] Further, such as Figure 4 As shown, a second motor 12 is fixedly installed on the top of the cabinet 1, a lifting screw 13 is fixedly installed on the output end of the second motor 12, an outer thread of the lifting screw 13 is connected to an internal thread barrel 14, and a top cover 15 is fixedly installed on the top of the internal thread barrel 14, as shown in FIG. Figure 3 As shown, a connecting rod 16 is fixedly installed at the bottom of the top cover 15, a baffle 17 is fixedly installed on the outer side of the connecting rod 16, the baffle 17 is slidably connected to one side of the cabinet 1, a limit block 18 is fixedly installed on one side of the cabinet 1, and the connecting rod 16 is slidably connected to the inside of the limit block 18.

[0023] It should be noted that, when heat dissipation is not performed, the second motor 12 can be started to cause the top cover 15 to descend and fit into the cabinet 1, and at the same time, the connecting rod 16 slides downward on the inner side of the limit block 18, so that the baffles 17 on both sides descend to close the heat dissipation holes on both sides of the cabinet 1, thereby preventing dust from entering the interior of the cabinet 1 and causing an increase in dust inside the cabinet 1.
