Problems solved by technology
When the traditional 10KV wand is used to operate the drop switch and vacuum switch, due to the influence of the weather and the surrounding communication lines, dense branches or buildings, the operating space of the staff is limited, which often leads to the fall of the fuse tube and the vacuum. The phenomenon of switch decoupling and decoupling not only wastes operating time and damages electrical equipment, but also increases the economic cost of distribution network line operation and maintenance
[0003] The traditional 10kV rod head is fixed, the operation part of the rod head is smooth and there is no locking mechanism, which is the key to the failure of smooth operation. Strong winds, thunderstorms and other bad weather are the main reasons for frequent failures, which have a great influence on the success rate of switch operation. influences

The invention relates to the technical field of power construction, in particular to an insulating rod with an adjustable top part. According to the technical scheme disclosed by the invention, the insulating rod with the adjustable top part comprises a hollow bar, a bending device, a hollow rod head and a line clamping device, wherein the bending device is arranged at the top part of the bar; the hollow rod head is arranged at the upper part of the bending device; the line clamping device is arranged at the side surface of the rod head; a lighting device isarranged at the side surface, close to the line clamping device, of the rod head; and the air pressure regulating device is arranged at the bottom of the bar. Compared with the prior art, the insulating rod has the beneficial effects of being low in processing cost, simple and compact in structure, convenient, effective, rapid and flexible to use and operate, small in occupied space, high in service efficiency, accurate and effective; and manpower and material resources are saved; and the safety of an operator is ensured.
Description
technical field [0001] The invention relates to the technical field of electric power construction, in particular to an adjustable ring rod at the top. Background technique [0002] With the continuous and rapid growth of social economy, industrial power consumption has increased significantly, and the method of voltage transmission is adopted in the process of power transmission to reduce power loss. High-voltage transmission is a method of boosting the output voltage of the generator through a transformer in a power plant and then transmitting it. The reason why this method is used for power transmission is that in the case of the same power transmission power, the higher the voltage, the smaller the current, so that high-voltage power transmission can reduce the current during power transmission, thereby reducing the heat loss caused by the current and reducing the material used for long-distance power transmission. cost. High-voltage power is easy to cause harm to pers...
