Description

Technical Field

[0001] This utility model relates to the field of transformers, specifically an ice-melting transformer. Background Technology

[0002] An ice-melting transformer is a power device used to solve the problem of icing on transmission lines. By applying a specific voltage to the icy line, it generates a short-circuit current and heats up the line, thereby achieving the purpose of melting ice and ensuring the safe and stable operation of the power grid.

[0003] In existing technologies, the cabinet is usually quite heavy and the weight distribution is uneven. During installation, it is easy for the center of gravity of the cabinet to shift, which may lead to tilting or even overturning. The heat generated by the resistance of the line itself melts the ice. The transformer generates a lot of heat due to frequent current changes. Dust and impurities in the outside air may enter the cabinet with the airflow. Utility Model Content

[0004] The purpose of this utility model is to provide an ice-melting transformer that can prevent the cabinet from tipping over and damaging internal parts during installation, can dissipate heat in time to extend its service life, can prevent dust from entering, ensure the safe and stable operation of the equipment, and reduce maintenance costs, thus solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An ice-melting transformer includes a pad, a first groove at the upper end of the pad, a plurality of limiting tubes fixed to the lower end of the inner wall of the first groove, shock absorbers fixed to the inner wall of the limiting tubes, a rubber pad fixed to the upper end of the limiting tubes, a support plate fixed to the upper end of the plurality of shock absorbers, a fixing block fixed to the upper end of the pad, a second groove at one side of the fixing block, an electric cylinder fixed to the inner wall of the second groove, a baffle fixed to the output end of the electric cylinder, and a ventilation mechanism provided on one side of the pad.

[0007] Preferably, the ventilation mechanism includes a third groove opened on one side of the pad, a plurality of fourth grooves evenly opened on the upper end of the pad, a filter screen fixed to the inner wall of the third groove, and a fan fixed to the inner wall of the third groove.

[0008] It is worth noting that the device is cooled by blowing air from the third tank into the fourth tank using a fan.

[0009] Preferably, the output end of the electric cylinder is located at the upper end of the plurality of fourth grooves, the lower end of the baffle is located at the upper opening of the plurality of fourth grooves, and the width of the baffle is greater than the diameter of the fourth groove.

[0010] It is worth noting that the electric cylinder pushes the baffle to cover the fourth tank, preventing dust from falling into the fourth tank when the fan is not in use.

[0011] Preferably, the fourth groove is L-shaped, and multiple fourth grooves are interconnected, with the fourth groove being interconnected with the third groove.

[0012] It is worth noting that the L-shaped opening directs the airflow to the device for cooling.

[0013] Preferably, the output end of the shock absorber is higher than the upper end of the rubber pad, and the support plate contacts the shock absorber first when it is compressed, with the upper end of the support plate and the upper end of the pad being flush.

[0014] It is worth noting that the support plate compresses the shock absorber for initial cushioning to prevent the device from being too heavy, and then a rubber pad provides secondary cushioning.

[0015] Preferably, the inner wall of the third groove is separated from the lower end of the pad by four centimeters.

[0016] It is important to note that the fan should be prevented from sucking dust from the ground into the fourth tank.

[0017] Preferably, a voltage regulating switch cabinet is slidably installed on the upper end of the support plate.

[0018] It is worth noting that the voltage regulating switchgear has many internal parts, and shock absorbers and rubber pads are used to cushion the impact.

[0019] Preferably, an anti-slip pad is fixed to the lower end of the pad.

[0020] It is worth noting that the anti-slip mat prevents the device from moving.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention places the cabinet on the upper part of a support plate and utilizes multiple shock absorbers connected below the support plate to evenly distribute the weight of the cabinet onto each shock absorber. The shock absorbers themselves have elastic deformation capabilities and can absorb part of the impact force through their own compression, avoiding uneven stress on the support structure caused by concentrated weight, thus reducing the risk of cabinet tipping over at the source. At the same time, they initially buffer the impact force during placement, reducing direct impact on internal parts. The rubber pads have good elasticity and deformation capabilities, which can further absorb the remaining impact force, forming a double buffering mechanism of shock absorbers and rubber pads. This minimizes the impact of cabinet vibration and impact on internal precision parts, ensuring that parts are not damaged during installation. The fourth slot serves as a heat dissipation channel. Normally, it is closed by a baffle to prevent external debris from entering when the equipment is not dissipating heat. When the equipment generates a lot of heat and needs to dissipate heat, the baffle is driven by an electric cylinder to move backward, exposing the slot and creating an air circulation channel between the inside of the cabinet and the outside. The filter screen has a fine pore structure, which can intercept dust particles in the air while ensuring air circulation, preventing them from entering the inside of the cabinet, especially the third slot.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To address the risks of cabinet tilting or even overturning due to the inherent weight and uneven weight distribution in existing technologies, which can easily cause the cabinet's center of gravity to shift during installation, this technical solution utilizes the heat generated by the line's own resistance to melt ice buildup. It also addresses the issues of transformers generating significant heat due to frequent current changes and the potential for dust and impurities from the outside air to enter the cabinet via airflow.

[0031] An ice-melting transformer includes a pad 1. A first groove 2 is formed at the upper end of the pad 1. Multiple limiting tubes 3 are fixed to the lower end of the inner wall of the first groove 2. Shock absorbers 4 are fixed to the inner wall of the limiting tubes 3. A rubber pad 5 is fixed to the upper end of the limiting tubes 3. A support plate 6 is fixed to the upper end of the multiple shock absorbers 4. A fixing block 7 is fixed to the upper end of the pad 1. A second groove 8 is formed on one side of the fixing block 7. An electric cylinder 9 is fixed to the inner wall of the second groove 8. A baffle 10 is fixed to the output end of the electric cylinder 9. A ventilation mechanism 11 is provided on one side of the pad 1. The output end of the shock absorber 4 is higher than the upper end of the rubber pad 5. When the support plate 6 is compressed, it first contacts the shock absorber 4. The upper end of the support plate 6 is flush with the upper end of the pad 1. A voltage regulating switch cabinet is slidably installed on the upper end of the support plate 6. An anti-slip pad is fixed to the lower end of the pad 1.

[0032] The ventilation mechanism 11 includes a third groove 12 opened on one side of the pad 1. Multiple fourth grooves 13 are evenly opened on the upper end of the pad 1. A filter screen 14 is fixed to the inner wall of the third groove 12. A fan 15 is fixed to the inner wall of the third groove 12. The output end of the electric cylinder 9 is located at the upper end of the multiple fourth grooves 13. The lower end of the baffle 10 is located at the upper opening of the multiple fourth grooves 13. The width of the baffle 10 is greater than the diameter of the fourth groove 13. The fourth grooves 13 are L-shaped. The multiple fourth grooves 13 are interconnected. The fourth grooves 13 are interconnected with the third groove 12. There is a four-centimeter gap between the inner wall of the third groove 12 and the lower end of the pad 1.

[0033] Working principle: First, the voltage regulating switch cabinet is placed on the upper end of the support plate 6. The support plate 6 presses down on the shock absorbers 4, and the weight is evenly distributed on the upper end of multiple shock absorbers 4. The weight of the voltage regulating switch cabinet is uneven, which can easily cause it to tip over. When the support plate 6 presses down excessively, the lower end of the support plate 6 will reach the upper end of the rubber pad 5. The rubber pad 5 has a certain deformation capacity, which cushions the support plate 6 again, avoiding collisions and damage to the precision parts inside the cabinet during the installation of the voltage regulating switch cabinet. Since the voltage needs to be changed multiple times to melt the ice on the line, a lot of heat will be generated. If a lot of heat is not dissipated, it will affect the service life of the machine. Therefore, the electric cylinder 9 is opened. The output end of the electric cylinder 9 drives the baffle 10 to move backward. The baffle 10 moves backward, exposing the upper end of multiple fourth slots 13. The fan 15 is turned on, and the air is blown through the fourth slots 13 to cool the machine. The filter screen 14 prevents dust from falling into the interior of the third slot 12.
