Description

Technical Field

[0001] The invention relates to the technical field of bare wire insulation wrapping, and in particular to a 35kV overhead power transmission line insulation sheet cold pressing and bonding wrapping robot. Background Art

[0002] Overhead transmission lines are power lines erected on the ground and insulated by insulators and air. Overhead lines consist of conductors, overhead ground wires, insulator strings, poles, grounding devices, and other parts. In actual operation, 10kV lines can be insulated by replacing insulated conductors or live insulation coating robots on overhead bare wires, quickly transforming the insulation technology of local areas of the line without being constrained by power supply conditions and the environment, effectively solving the problem of power outages required for insulation transformation. 35kV lines generally use insulation coating robots for operation, and the thickness of the insulation layer must reach more than 4 mm to meet the standards. Due to the complexity of the construction site environment and overhead conductors, the insulation coating robots cannot solve the existing problems in the operation process and quality control, mainly as follows:

[0003] 1. The storage period of insulating coating is too short;

[0004] 2. Low operating efficiency;

[0005] 3. The coating quality cannot be guaranteed. Affected by the sag of the conductor and the weight of the robot, the sag of the conductor is 1-2 meters lower than the running line. The robot coating process increases the up and down slopes, making the robot go up slowly and go down quickly. As a result, the thickness of the coated insulation layer is uneven.

[0006] 4. The curing method of the coating affects the coating quality. At present, most of the domestic insulating coatings are room temperature curing silicone rubber systems. The characteristics of this coating are fast surface drying and the coating cures by absorbing moisture from the outside to the inside. It has outstanding advantages. However, if the insulating glue coating process cannot reach positive pressure, bubbles will remain in the aluminum stranded wire, thereby reducing the insulation level of the insulating layer. This is the main reason why the thickness of the insulating glue coating and its withstand voltage value cannot be linearly related. Summary of the invention
