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

Abstract

The invention relates to a high-voltage integrated 10kV pole-mounted transformer table complete device which comprises a cabinet body installed on a transformer, a wire inlet sleeve terminal used for being connected with a high-voltage wire is arranged at the top of the cabinet body, a wiring port and an auxiliary stabilizing mechanism are arranged at the bottom of the cabinet body, and the auxiliary stabilizing mechanism is used for clamping the transformer. A monitoring module for monitoring whether the transformer works or not is also arranged in the cabinet body; a sulfur hexafluoride load switch, a high-voltage lightning arrester and a high-voltage fuse are arranged in the cabinet body, the wire inlet sleeve terminal is connected with the sulfur hexafluoride load switch, the sulfur hexafluoride load switch is connected with the transformer through the high-voltage fuse, the high-voltage lightning arrester is connected to a line between the high-voltage fuse and the sulfur hexafluoride load switch, and the high-voltage fuse is connected with the high-voltage fuse. The high-voltage lightning arrester is used for lightning protection. A complete and independent high-voltage cabinet is formed, no redundant elements and cables are exposed outside, and corrosion and aging of the elements caused by severe environments such as sunshine, strong wind, heavy snow and the like are also avoided.
