Description

Technical Field

[0001] This utility model relates to a protective cover, and more particularly to a retractable protective cover. Background Technology

[0002] Currently, the high-voltage side of transformers, PT transformers, and surge arresters are often exposed to complex environments and are susceptible to external factors such as rain and humidity, contact with foreign objects, animal attacks, and ultraviolet aging, which can lead to a decline in insulation performance or mechanical damage.

[0003] Traditional protective covers are mostly made of a single type of insulating material. Although they can provide basic protection, they have the following limitations: high-voltage side equipment, PT transformers, and surge arresters come in a variety of models, and existing protective covers have poor versatility and are difficult to cover the sizes of different equipment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a retractable protective cover suitable for the high-voltage side of transformers, PT transformers, and surge arresters.

[0005] The protective cover of this utility model includes an L-shaped protective cover with an L-shaped break line running through the entire product, separating the product along the break line. There is also a break line on the opposite side of the tail section. A tool insertion point is located on the outer side of the tail section. The head section has a corresponding slot and a cylindrical section that can be inserted into the head of the protective cover. The outer side of this cylindrical section has a protruding structure that engages with the slot in the head section, creating a telescopic structure at the head of the protective cover, making them difficult to separate. Below the cylindrical section, on the side opposite the break line on the protective cover, there is also a break line that runs completely through the product along its length.

[0006] The retractable protective cover described above is made of insulating materials such as PP, PC, and PVC. It features simple manufacturing, low cost, and convenient installation and operation. Attached Figure Description

[0007] Figure 1 This is a schematic diagram of the structure of Embodiment 1 of the present utility model;

[0008] Figure 2 This is a structural schematic diagram of Embodiment 2 of the present invention. Detailed Implementation

[0009] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0010] Example 1:

[0011] like Figure 1 , 2 As shown, this utility model discloses a retractable protective cover, including an L-shaped protective cover 1. The protective cover 1 has an L-shaped first disconnect line 2 running through it, dividing the protective cover 1 along the first disconnect line 2. A second disconnect line 8 is provided on the side opposite to the first disconnect line 2 at the tail end, further dividing it. The second disconnect line 8 extends to the head of the protective cover 1, and has a tool insertion point 3 on the outer side of its tail end. The head end has a corresponding slot 4 and a cylindrical section 5 that can be inserted into the head of the protective cover 1. There is a T-shaped protruding structure 6 on the outer side. The bottom of the T-shaped protruding structure 6 is fixed to the cylindrical body 5. The middle part of the T-shaped protruding structure 6 is slidably set in the slot 4. The protruding parts on both sides of the top of the T-shaped protruding structure 6 are stuck on the outside of the cylindrical body 5. The protruding structure 6 and the slot 4 of its head part cooperate to form a telescopic structure of the cylindrical body 5 at the head of the protective cover 1, and the two are not easy to separate. Below the cylindrical body 5, on the side directly opposite to the first disconnect line 2 on the protective cover 1, there is a third disconnect line 7. The third disconnect line 7 completely penetrates the cylindrical body 5 along the length direction.

[0012] When in use, insert the tool into the locking point 3 to open the protective cover and make it elastically deform. Then, put it on the high-voltage side of the transformer, PT transformer or surge arrester. Then, release the tool to return it to the closed state. The cylindrical body 5 forms a telescopic structure at the head of the protective cover 1, so as to adapt to the high-voltage side of transformers, PT transformers or surge arresters of different sizes and specifications, and has good versatility.

Claims

1. A retractable protective cover, characterized in that: The product includes an L-shaped protective cover with an L-shaped break line running through the entire product, separating it along the break line. There is also a break line on the opposite side of the tail section from the L-shaped break line. A tool insertion point is located on the outer side of the tail section. The head section has a corresponding slot and a cylindrical section that can be inserted into the head of the protective cover. The outer side of this cylindrical section has a convex structure that engages with the slot in the head section, creating a telescopic structure at the head of the protective cover, making them difficult to separate. Below the cylindrical section, on the side opposite the break line on the protective cover, there is another break line that runs the entire length of the product.
