Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a protective device for the shell of a box-type transformer. Background Art

[0002] A box-type transformer integrates a traditional transformer in a box-type housing, which has the advantages of small volume, light weight, low noise, low loss, and high reliability. The main functions of a box-type transformer include voltage conversion, power transmission, power protection, and power distribution. A box-type transformer can convert a high-voltage DC or AC power supply into a low voltage to meet the power supply requirements of various distribution systems. For example, power electronic devices may need a low voltage to operate, and a box-type transformer can provide appropriate voltage conversion. A box-type transformer has multiple protection functions such as overload protection, short-circuit protection, high-voltage protection, and low-voltage protection, effectively protecting the safety of equipment and personnel and avoiding accidents such as fires, explosions, and electric shocks caused by electrical failures. A protective housing is provided outside the box-type transformer. However, the protective housing of the box-type transformer is relatively weak. After encountering bad weather, it is easy to cause pits on the top of the housing, affecting the use, and it is relatively inconvenient to replace and repair. Moreover, when encountering strong winds, it is easy to cause the top of the protective housing to break off, affecting the use. Summary of the Utility Model

[0025] In the embodiment of the present disclosure, as Figure 3 compared with Figure 4 shown, on both sides of the top end of the protective body 1, uniformly arranged top rod assemblies 101 are respectively fixed. The top rod assembly 101 is a T-shaped shaft structure and is inserted into the inside of the kit 102, which improves the positioning and fixing effect on the kit 102. An outer groove 103 is opened at the middle position on the outer side of the kit 102 for embedding a connection structure 201, so that the connection structure 201 is positioned and connected with the kit 102; the bottom of the protective body 1 is fixedly connected with a base assembly 105. On both sides of the base assembly 105, two positioning grooves 106 are respectively opened. The positioning grooves 106 are circular ring structures.

Then, the lifting rope is controlled to be embedded inside the positioning groove 106 and at the same time is embedded inside the V-shaped groove of the contact block 108, so that the lifting rope stably hoists the protection body 1 to move and displace, and conveniently controls the protection body 1 to move to the installation position. Then, the protection body 1 and the base assembly 105 are fixed and used. Then, the transformer is controlled to be installed and used, so that the protection body 1 and the top piece 2 are used for external protection of the transformer. When encountering bad weather, if encountering hail or falling objects, it can contact the contact piece 204. The contact piece 204 eliminates the impact force of the collision by means of elasticity, improves the protection effect on the top piece 2, and prevents the top piece 2 from being damaged. At the same time, the contact piece 204 can be conveniently replaced through the insertion plate structure 205 and the pressing plate structure 206. If encountering strong winds, when the strong wind pulls the top piece 2, after the top piece 2 is stressed, the force is transmitted to the kit 102 through the connection structure 201. By means of the elasticity of the kit 102, the pulling force and the shaking force are eliminated, and the top piece 2 is prevented from being damaged or detached.
