Description

Technical Field

[0001] The utility model relates to the technical field of box-type transformer substations, in particular to a miniaturized box-type transformer substation which is convenient to maintain. Background Art

[0002] A box-type substation, also known as a prefabricated substation, consists of high-voltage switchgear, distribution transformers, and low-voltage distribution equipment, all preassembled in one or more boxes at the factory to form a complete substation. Box-type substations can be fully enclosed or mobile, and are widely used in urban grid construction and renovation, mines, factories, oil and gas fields, and wind power stations. As a new type of complete power transformation and distribution system, they replace existing civil distribution rooms and substations.

[0003] During continuous operation, the internal equipment of the box-type substation will generate a lot of heat, especially for the transformer. Long-term overheating can easily cause the transformer or other internal equipment to malfunction. Therefore, staff are required to frequently perform inspections and maintenance, which leads to certain limitations in the use of the box-type substation. Utility Model Content

[0004] The main purpose of the utility model is to provide a miniaturized box-type transformer that is easy to maintain and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A miniaturized box-type transformer with easy maintenance includes a box-type substation, a transformer is installed on the lower inner wall of the box-type substation, two lighting devices are installed on the front of the upper inner wall of the box-type substation, a controller is installed in the middle of the right end of the box-type substation, a temperature sensor is installed on the upper front end of the controller, a liquid cooling device is installed on the lower right end of the box-type substation, an installation groove is opened on the upper right end of the box-type substation, a ventilation device is installed in the installation groove, a protective ceiling is installed on the upper left and upper right ends of the box-type substation, and box doors are installed on the front and rear ends of the box-type substation.

[0007] Preferably, the liquid cooling device includes a water tank and a heat-conducting housing, a tank cover is installed on the right upper end of the water tank, a water pump is installed on the left upper end of the water tank, a circulating water pipe is installed on the left end of the water pump and the upper left end of the water tank, the circulating water pipe is located in the heat-conducting housing, the heat-conducting housing is installed on the outer surface of the transformer, the water tank is installed on the lower right end of the box-type substation, and the water pump and the controller are electrically connected. The water in the water tank is pumped by the water pump and transported to the circulating water pipe, which is located in the heat-conducting housing, which is installed on the outer surface of the transformer. When the water flows back to the water tank through the circulating water pipe, it can quickly remove the heat in the heat-conducting housing, thereby effectively cooling the transformer.

[0008] Preferably, the ventilation device includes a mounting base, with mounting brackets mounted on the left and right inner walls of the mounting base, and fans mounted on corresponding ends of the mounting brackets. The mounting base is fixedly mounted in the mounting slot, and the two fans are electrically connected to the controller. The fans are activated by the controller to quickly discharge hot air from the box-type substation, further improving the heat dissipation effect of the device.

[0009] Preferably, the lighting device includes two mounting brackets, a lamp holder mounted between the two mounting brackets, a plurality of lamp beads mounted at the lower end of the lamp holder, the two mounting brackets being fixedly mounted on the front of the upper inner wall of the box-type substation, and the lamp holders being electrically connected to a controller. The controller can activate the lamp holders on the lighting device to illuminate, providing maintenance personnel with a better field of view and facilitating equipment maintenance.

[0010] Preferably, the heat-conducting shell is U-shaped and is made of copper.

[0011] Preferably, the temperature sensor is installed on the right inner wall of the box-type substation.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the design of the temperature sensor on the controller, it can detect the temperature inside the box-type substation. When the temperature exceeds the set value, the controller starts the water pump on the liquid cooling device, and the water pump then extracts the water in the water tank and transports it to the circulating water pipe. The circulating water pipe is located in the heat-conducting shell, and the heat-conducting shell is installed on the outer surface of the transformer. The heat-conducting shell is made of copper and has good thermal conductivity. Therefore, the heat-conducting shell can quickly absorb the heat generated by the transformer. When the water flows back to the water tank through the circulating water pipe, it can quickly take away the heat in the heat-conducting shell to effectively dissipate the heat of the transformer. In addition, the controller can also start the fan on the ventilation device, so that the hot air inside the box-type substation can be quickly discharged, further improving the heat dissipation effect of the device and reducing the failure of the internal equipment of the box-type substation due to overheating.

[0014] 2. When the internal equipment of the box-type substation needs repair or maintenance, the controller can start the lamp holder on the lighting device to illuminate, providing maintenance personnel with a better field of view and facilitating their maintenance of the equipment.

[0024] The liquid cooling device 2 comprises a water tank 20 and a heat-conducting outer shell 21. A tank cover 24 is mounted on the upper right side of the water tank 20. A water pump 22 is mounted on the upper left side of the water tank 20. A circulating water pipe 23 is mounted on the left end of the water pump 22 and the upper left end of the water tank 20.

The water tank 20 is mounted on the lower right side of the box-type substation 1. The water pump 22 is electrically connected to the controller 7. The heat-conducting outer shell 21 is U-shaped and made of copper. Water from the water tank 20 is pumped by the water pump 22 and transported to the circulating water pipe 23, which is located within the heat-conducting outer shell 21, which is mounted on the outer surface of the transformer 5.
