Description

Technical Field

[0001] The invention relates to the technical field of emergency repair towers, in particular to an insulating pull rod emergency repair tower. Background Art

[0002] Power repair towers are core infrastructure for power grid emergency response. They are primarily used to quickly replace fallen towers and broken lines caused by natural disasters (such as typhoons and ice storms), external damage, or aging equipment, restoring power supply in the shortest possible time. This is especially true in high-voltage / ultra-high-voltage transmission line repair scenarios.

[0003] Traditional emergency repair towers mainly use lattice-type angle steel towers or integrally hoisted steel tower structures. Angle steel towers require hundreds of components to be bolted together on site one by one. The average tower assembly time exceeds 8 hours, which cannot meet the "golden 6-hour" emergency repair window period after a major accident. Non-standard components cannot be interchanged, and different voltage level lines require multiple sets of tower types. The inventory and transportation costs are high. The tower body requires a pre-cast concrete foundation. The construction period is extended by 2-3 days in soft geological, frozen soil or heavy rain environments. The crossarms and tower columns are directly welded or customized, and lack a modular reinforcement system. Structural deformation is prone to occur under strong wind conditions. Therefore, how to carry out modular emergency repair towers with rapid disassembly and assembly, structural interchangeability, and strong foundation adaptability to fundamentally improve the emergency response capability of the power grid is an urgent problem that needs to be solved by technicians in this field.
