Insulating layer coating system for overhead cable transformation

Abstract

The invention discloses an insulating layer coating system for overhead cable transformation, and the system comprises a wrapping frame for clamping a cable and a discharging frame for discharging an insulating material; the wrapping frame comprises an upper frame and a lower frame; one side of the upper frame and one side of the lower frame are hinged with each other through a hinge, and the other side of the upper frame and the other side of the lower frame are connected with each other through a bolt; the upper frame and the lower frame are each provided with an empty groove used for wrapping a cable, one end of each empty groove is provided with a rolling wheel used for driving to move, the other end of each empty groove is provided with a spraying hole used for spraying an insulating material, the spraying holes are communicated with a discharging pipe through corresponding communicating grooves, and the discharging pipe is communicated with a discharging opening in the discharging frame through a communicating pipe. According to the system device, the pressure of gravity on the cable can be reduced, so that the damage to the cable is reduced, and the operation continuity is improved; meanwhile, the air flow speed at the two ends of the wrapping frame can be greatly increased, impurities on the cable can be cleaned, and cooling and solidification of an insulating coating can be accelerated.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance, in particular to an insulating layer coating system used for the reconstruction of overhead cables. Background technique [0002] In order to reduce power supply failures caused by external factors such as trees, birds and foreign objects, and improve the reliability of power supply, overhead insulated wires are gradually being used. Although my country has carried out two large-scale transformations of the rural distribution network, the majority The coverage of overhead insulated conductors in rural distribution networks is still low. The existing bare and leaky power lines may cause dangers such as short circuits due to trees, branches and leaves, and birds or other foreign objects may also cause power failures. In addition, in cold weather, short circuits may occur due to icing. However, if the original bare wires are directly removed and replaced, it will not only take a l...

Problems solved by technology

[0002] In order to reduce power supply failures caused by external factors such as trees, birds and foreign objects, and improve the reliability of power supply, overhead insulated wires are gradually being used. Although my country has carried out two large-scale transformations of the rural distribution network, the majority The coverage of overhead insulated conductors in rural distribution networks is still low

The existing bare and leaky power lines may cause dangers such as short circuits due to trees, branches and leaves, and birds or other foreign objects may also cause power failures. In addition, in cold weather, there may be short circuits caused by icing

However, if the original bare wires are directly removed and replaced, it will not only take a long time and cost a lot, but also greatly affect the surrounding power consumption.
