Problems solved by technology

[0002] According to the installation of the high-voltage part, the existing 10kV pole-mounted transformer station complete set is divided into three installation methods: side-mounted high-voltage cable connection method, side-mounted high-voltage wire connection method and front-mounted high-voltage wire connection method, such as figure 1 , 2 , 3, any installation method must be installed with materials such as high-voltage drop-out fuses, high-voltage arresters, high-voltage post insulators, various types of clamps, high and low-voltage cable conductors, and iron fittings for all components. on the pole, such as Figure 4 As shown, the high-voltage parts (drop-out fuses, arresters, insulators, clamps, wires, etc.) of the above-mentioned methods are relatively scattered, Figure 4 Among them, ① is a dropout fuse, ② is a lightning arrester, ③ is a post insulator, ④ is a grounding wire, ⑤ is a parallel trench clamp, ⑥ is a high-voltage down conductor, ⑦ is a transformer connection line, ⑧ is a transformer, and ⑨ is a comprehensive distribution Electric box; has the following defects:

[0004] 2. Time-consuming and labor-intensive

A set of devices generally takes about 6 people and takes half a day to complete, which takes up a lot of people and takes a long time

[0005] 3. Unsightly

like Image 6 As shown in the scene pictures, there are many high-voltage components. In order to ensure the electrical safety distance between the three phases, the components are installed at a large distance, and it is messy after connecting the high-voltage lines.

[0006] 4. Not safe

High-voltage components are exposed to the air. Long-term wind and sun, strong wind, heavy snow and freezing weather can easily cause aging and damage of high-voltage parts, and high-voltage conductive parts are easy to oxidize. After oxidation, the contact resistance increases, which is easy to cause fire.

[0007] 5. Power transmission operation is prone to accidents

Because the drop-out fuse is used as the switching element for stopping power transmission, the staff needs to use the operating lever on the lower pole to switch the ABC three-phase drop-out fuse in a certain order. If the order is wrong, or the transformer is faulty, etc., It is easy to cause arc discharge or even a short circuit accident. At this time, the operator has no way to escape on the pole, which is very unsafe
