Description

A device for securing a bottle with electricity from the ground

technical field

The utility model relates to a device for fastening a bottle with electricity charged from the ground, belonging to the technical field of electric tools.

Background technique

Electricity is an energy source that uses electrical energy as power. The primary energy in nature is converted into electricity through mechanical energy devices, and then the electricity is supplied to each user through power transmission, transformation and distribution. The transmission of electric energy, together with substation, distribution and consumption, constitutes the overall function of the power system. Through power transmission, far apart (up to thousands of kilometers) power plants and load centers are connected, so that the development and utilization of electric energy transcend geographical restrictions. Compared with other energy transmissions (such as coal transportation, oil transportation, etc.), power transmission has low loss, high efficiency, flexibility and convenience, easy regulation, and less environmental pollution; power transmission can also connect power plants in different locations to implement peak-to-valley transmission. adjust. Power transmission is an important manifestation of the superiority of electric energy utilization. In modern society, it is an important energy artery.

Power grid construction mainly uses poles or iron towers to build power distribution and transmission lines. When erecting lines, support bottles are required for insulation isolation and support for the lines. The support bottles are often made of porcelain, so the support bottles are also called porcelain bottles. It is a needle-type power porcelain bottle, which is generally made of insulating parts (such as porcelain parts) and metal accessories (such as steel feet, iron caps, flanges, etc.) glued or mechanically clamped. Insulators are widely used in power systems, generally belong to external insulation, and work under atmospheric conditions. Overhead transmission lines, busbars of power plants and substations, and external live conductors of various electrical equipment must be supported by insulators and insulated from the ground (or grounding) or other conductors with potential difference.

The transmission lines on the poles and towers have been affected by strong wind, rainstorm, temperature and other environments for a long time, and the vibration of the wires will cause the screws of the support bottles of the transmission line to loosen, and the fall of the support bottles will cause faults such as line grounding. Check whether it is loose, and fasten the loose bottle in time.

However, the existing insulating operating rod is installed with a device for tightening the bottle support. According to the size of the bottle support bolt, it can be replaced frequently, and the support bottle can be fastened for both high and low voltage lines; the current tightening line support bottle can only be powered off. When the height of the high and low voltage lines changes greatly, the length of the insulating rod cannot be adjusted; holding the rod for a long time consumes physical strength, making it difficult to operate when the force is rotated and tightened; the support bottle with a higher height cannot be observed.
