Description

Technical Field

[0001] The invention belongs to the technical field of overhead installation frames for cables or wires, and relates to a power distribution network frame with an ice-covering monitoring function. Background Art

[0002] A distribution network refers to an electric power network that receives electric energy from a transmission network or a regional power plant and distributes it on-site or in stages according to voltage to various types of users through distribution facilities. It consists of overhead lines, cables, poles, distribution transformers, disconnectors, reactive power compensators and other ancillary facilities, and plays an important role in distributing electric energy in the power network. Existing distribution grids are generally used to install power grids. Once they encounter extreme weather, such as ice disasters, they may cause line breakage. Ice covering transmission lines or equipment will increase their weight, which may cause line or equipment breakage and power outages. Ice accumulation on insulators may also increase the load on insulators, reduce insulation performance, and increase the risk of short circuits in the lines. It will also affect the spacing between conductors. The weight of the ice may reduce the distance between the conductors, causing a short circuit or breakdown between the conductors. It will also affect equipment operation. The impact of ice will hinder the operation of power grid equipment and may cause equipment damage. Therefore, the above problems need to be improved.

[0037] When encountering cold weather and a large amount of ice covers the power grid 25, the tension applied to the tension sensor 21 increases.
