Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of box-type transformer substations, and more specifically, to a box-type transformer substation with a ventilation system. Background Art
[0002] The ventilation structure for box-type substation is a device designed for ventilation and heat dissipation inside box-type substation. This ventilation structure usually includes a box shell, and a fan is installed on the inner wall of the box shell to suck external air into the box shell and dissipate heat inside the box shell. At the same time, a heat dissipation groove is also opened on the inner wall of the box shell, and a dustproof net is installed inside the heat dissipation groove to prevent dust and impurities from being sucked into the box shell. When it rains, rainwater flows along the top cover to the pressing mechanism, pushing the movable plate down, so that the through groove and the heat dissipation groove are staggered, and the heat dissipation groove is blocked by the movable plate, thereby preventing moisture from entering the inside of the box shell on rainy days and affecting the electrical components inside the box shell.
[0003] Citing patent CN116706744B, a ventilation structure for a box-type substation and a box-type substation, the operation of the motor drives the rotation of the output shaft, which in turn drives the fan blades to rotate to ventilate the inside of the substation body. At the same time, the operation of the opening mechanism will drive a number of fan-shaped plates to move, open the fixed cylinder, and achieve communication between the outside world and the substation body, thereby achieving ventilation of the substation body. Although the ventilation structure of the box-type substation is convenient for heat dissipation, when the motor speed is too fast, the extrusion circular plate will quickly push the U-shaped rod, causing the fan-shaped plate to open and close too quickly and the opening and closing amplitude to decrease. This situation will significantly reduce the ventilation efficiency and is not conducive to the heat dissipation inside the substation. This will lead to poor ventilation efficiency, so the above needs to be improved. Utility Model Content
