[0001] The utility model relates to the technical field of power systems, in particular to a voltage transformer cabinet. Background Art
[0002] A voltage transformer is a device used to measure the voltage in a high voltage system and reduce it to a lower safety level. It is also called a voltage transformer or voltage transformer. Voltage transformers are usually used to reduce the voltage of a high voltage system to a low voltage level suitable for use in measuring, protecting and controlling equipment. A voltage transformer cabinet is a device used to install and protect voltage transformers. It is usually made of metal or insulating materials and has appropriate size and structure to accommodate and fix the voltage transformer. The voltage transformer is usually placed in a cabinet. In order to prevent the equipment from getting damp, the voltage transformer is usually placed on a bracket that is separated from the bottom of the cabinet. The voltage transformer releases heat during operation, forming heat accumulation in the cabinet, affecting the overall cabinet ventilation and heat dissipation, and the overall heat dissipation efficiency is low.
[0003] To this end, we propose a voltage transformer cabinet. Utility Model Content

The inner cavity is fixedly connected with an air outlet pipe 42, and the air outlet pipe 42 has multiple air outlets. A support assembly 7 is provided at the bottom of the inner cavity of the voltage transformer cabinet 1. The support assembly 7 includes a support rod 71 fixedly connected to the bottom of the inner cavity of the voltage transformer cabinet 1. The number of support rods 71 is four, and the tops of the four support rods 71 are fixedly connected with a support frame 72. The inner cavity of the support frame 72 is provided with a plurality of heat dissipation holes 73, so that air can circulate at the bottom of the support frame 72. The inner cavity of the support frame 72 is equipped with a voltage transformer 6, and the air outlet end of the air outlet pipe 42 blows toward the side wall of the voltage transformer 6. The gas blown out by the blower 41 can perform preliminary heat dissipation on the voltage transformer 6 through the air outlet pipe 42. By opening a plurality of heat dissipation holes 73 on the support frame 72, the heat at the bottom of the voltage transformer 6 can be better dissipated.
[0025] A heat dissipation component 5 is provided on the voltage transformer cabinet 1, and the heat dissipation component 5 includes a water tank 51 fixedly connected to the top of the voltage transformer cabinet 1, and the inner cavity of the water tank 51 stores coolant.

[0026] The working principle of this utility model:
[0027] During use, when the voltage transformer 6 is running, a large amount of heat will be generated. At this time, the blower 41 is started, and the wind of the blower 41 is blown out through the outlet pipe 42. Since the outlet of the outlet pipe 42 is aligned with the side wall of the voltage transformer 6, under the cooperation of the blower 41 and the outlet pipe 42, the gas blown out by the blower 41 can perform preliminary heat dissipation on the voltage transformer 6. The water pump 52 is started, and the coolant in the inner cavity of the water tank 51 flows into the circulation pipe 53, flows through the side wall of the voltage transformer cabinet 1, and the coolant in the water tank 51 circulates along the circulation pipe 53 for one circle and then flows back to the inner cavity of the water tank 51.

[0028] When in use, through the setting of the support assembly 7, the multiple heat dissipation holes 73 opened on the support frame 72 can make the heat at the bottom of the voltage transformer 6 be better dissipated, so that the bottom of the voltage transformer 6 can be better ventilated and heat-dissipated.
